Decatur, GA Leak Detection and Repair: 5 Slab Leak Signs
Estimated Read Time: 12 minutes
A hidden leak under your slab can destroy floors, warp cabinets, and invite mold before you see a drop. If you’re searching for slab leak symptoms, here are the five you must act on fast. Our licensed plumbers use camera inspections and pinpoint locating to stop damage early. Same-day help is available across Atlanta and North Georgia, and we provide upfront options so you can choose the right repair for your home and budget.
Why Slab Leaks Happen in Metro Atlanta
Slab leaks occur when pressurized water lines under your concrete foundation crack, corrode, or separate. In North Georgia, expansive clay soils can shift with seasonal moisture. That movement stresses copper or PEX lines and joints. Older homes that still have original copper lines are especially vulnerable to pitting corrosion.
Common triggers include high water pressure, chemical reactions between copper and the soil, and foundation movement. Minor pinholes can run for weeks before surfacing. By then, water has spread horizontally beneath the slab, soaking subfloor materials and wicking into walls.
Licensed plumbers use non-destructive tools to locate leaks fast. Our team confirms the exact line and depth so repairs are targeted, not guesswork. That keeps demolition to a minimum and reduces time to restore your home.
Symptom 1: Unexplained Water Bill Spikes
If usage jumps without a lifestyle change, suspect a continuous underground leak. Meter checks can confirm it. Shut off every fixture and appliance, then watch the meter. If it moves, water is escaping somewhere.
You may also notice your irrigation is off, yet the bill still rises. Slab leaks can waste hundreds of gallons per day. Catching this early prevents secondary damage like swollen baseboards and delaminated flooring.
What to do next:
- Verify the spike across at least two billing cycles if possible.
- Test the meter with all fixtures off.
- Call a licensed plumber for pressure testing and line isolation.
Symptom 2: Warm or Cold Spots on the Floor
A persistent warm area often points to a hot-water line leak under the slab. On tile or LVP, you may feel a temperature difference with bare feet. Carpet may feel slightly dry on top but warm underneath. A cold spot can happen on chilled lines, especially during heavy AC use.
Why this matters: temperature anomalies are one of the earliest slab leak symptoms. They also help narrow down the search area, which reduces diagnostic time and demolition.
What to do next:
- Note the exact location and size of the area.
- Avoid turning the water on and off repeatedly. Pressure swings can enlarge the leak.
- Schedule professional leak detection to confirm the line and depth.
Symptom 3: Flooring Damage, Buckling, or Hollow Sounds
Slab leaks saturate from the bottom up. Wood and laminate can cup, buckle, or separate. Tile may debond and start to sound hollow when tapped. Grout lines darken. In severe cases, baseboards swell and paint bubbles where moisture wicks into drywall.
These symptoms often appear in kitchens, laundry rooms, and bathrooms where supply lines run beneath the slab. Do not ignore cosmetic changes. They are structural red flags and mold risks if left untreated.
What to do next:
- Photograph the damage for insurance.
- Do not rip out flooring until the leak is located and stopped.
- Ask your plumber to coordinate repair steps with your flooring contractor for a cleaner restoration.
Symptom 4: Running Water Sounds With Fixtures Off
A faint hiss or whoosh in walls or floors can indicate a pressurized line leak. If your home is quiet and you still hear movement, check that toilets are not running and that irrigation and appliances are off. Continuous sound suggests a slab leak or an in-wall supply leak.
Professional tools can isolate zones quickly. Static pressure tests, acoustic listening, and tracer gas can pinpoint exact locations. Fast confirmation helps you avoid expanding damage while reducing exploratory demolition.
What to do next:
- Verify all fixtures and appliances are off.
- Check toilets by adding dye to the tank. If bowls colorize, repair flappers first.
- If sound persists, schedule detection before damage spreads.
Symptom 5: Damp Spots, Musty Odors, or Mold Near the Floor
Moisture that appears along baseboards, at cabinet toe-kicks, or in closet corners often traces back to a slab leak. Odors can show up before visible staining. Elevated humidity may also cause doors to stick and HVAC to run longer.
If you notice musty smells or recurring damp spots that return after mopping, act now. Long-term moisture invites mold, damages subfloor materials, and lowers indoor air quality.
What to do next:
- Ventilate the area and run a dehumidifier.
- Avoid bleaching porous materials. It does not fix the water source.
- Call a licensed plumber to locate and stop the leak, then address remediation.
How We Diagnose Slab Leaks Without Tearing Up Your Home
Targeted diagnostics save time and money. Here is the approach our licensed team uses:
- Pressure and isolation tests to determine if the hot, cold, or both lines are affected.
- Acoustic listening to detect pressurized water escaping beneath the slab.
- Thermal scanning to confirm temperature anomalies across floors.
- Sewer camera inspections when drain or sewer issues are suspected. A high-resolution camera transmits live footage to locate cracks, breaks, and obstructions. We determine the depth and location before excavation begins.
- Electronic line locating to map routes, minimizing exploratory demolition.
This non-destructive workflow gets you from symptom to solution quickly. Our goal is a precise plan that limits disruption and accelerates restoration.
Repair Options: From Spot Fixes to Reroutes
Every home is different. After detection, we present clear options with upfront pricing:
- Spot repair. We access the exact leak point, replace the damaged section, and restore the slab. Best for isolated failures on accessible, straight runs.
- Overhead or wall reroute. We abandon the leaking under-slab line and run new piping through walls or attic. This avoids cutting the slab and protects against soils that may keep shifting.
- Full or partial repipe. Recommended when multiple leaks or widespread corrosion are present, especially in older copper systems.
We also handle related work such as faucet and sink repairs, toilet repairs, drain cleaning, and water heater leak fixes. If frozen weather strikes, our controlled thawing safely warms pipes without overheating, then we repair any burst sections to current code.
What It Costs and What Affects Price
No two leaks are the same, so pricing reflects your home and the chosen repair path. Influencers include:
- Access. Cabinetry, built-ins, and slab thickness affect labor time.
- Material and age. Older copper may point to reroute or repipe instead of a one-off fix.
- Length of new pipe runs. Reroutes that span rooms cost more than short spot fixes.
- Restoration scope. Flooring and concrete patching vary by material.
We provide free estimates for replacements and financing options for larger projects. You will always see the plan and price before work begins.
Insurance, Documentation, and Code Compliance
Many policies cover access and repair to the failed line, and some help with restoration. Coverage varies, so call your carrier early. We document findings with photos and, when relevant, camera footage for clear claims.
All work is performed by licensed, insured professionals. Our public license numbers are HVAC CN210646 and Master Plumber MP209933. Meeting or exceeding Georgia code protects your home value and safety.
Preventing the Next Slab Leak
While not every leak is preventable, you can lower risk:
- Maintain normal household pressure, ideally 55 to 70 psi. Ask about a pressure-reducing valve if yours is high.
- Insulate vulnerable lines and address foundation drainage to reduce soil movement.
- Replace failing sections proactively in homes with repeated pinhole leaks.
- Schedule camera checks when you have recurring drain backups. Root intrusion or offsets in sewer lines can spread moisture and undermine slabs.
For Atlanta homeowners, watch for seasonal shifts in clay-heavy soil that can stress pipes. Early checks each spring and fall can catch issues before they escalate.

Suwanee AC Repair: AC Runs but Won’t Cool Your Home
Estimated Read Time: 9 minutes
AC running but not cooling your home is one of the most frustrating summer problems in Atlanta. The unit hums, vents push air, yet rooms stay warm. In this guide, you will learn why this happens, what you can safely check today, and when to call a pro for fast relief. If you need help now, our licensed team offers same-day AC repair throughout Atlanta and nearby suburbs.
Quick Checklist: What to Try Before You Call
If your AC is running but not cooling, start with these fast checks:
- Set thermostat to Cool and Auto, not On. Lower setpoint 3 to 5 degrees.
- Replace or clean the air filter. A clogged filter chokes airflow.
- Make sure supply vents are open and return grilles are clear.
- Inspect the outdoor unit. Clear leaves and debris. Ensure the fan spins.
- Check the electrical panel for a tripped breaker.
- Look for ice on indoor or outdoor lines. If present, turn the system Off and the fan On to thaw.
- Verify the condensate drain is not clogged or overflowing.
Homeowner tip: After any change, give the system 15 to 20 minutes to stabilize before rechecking temperatures.
Thermostat and Control Issues
The smallest setting can block cooling. Thermostats on Fan On will blow room temperature air non-stop. Incorrect schedules, dead batteries, or miscalibrated sensors can also undermine cooling.
What to do:
- Set mode to Cool and Fan to Auto.
- Replace batteries. Reboot smart thermostats if needed.
- Move heat-generating lamps or electronics away from the thermostat.
- If the thermostat is older or unreliable, ask about an upgrade. Smart models can improve comfort and efficiency when installed and configured correctly.
When to call: If the display is blank after a battery change, controls short cycle, or the system ignores commands, you likely have a control or low-voltage wiring issue that needs a licensed technician.
Airflow Blockers: Filters, Coils, and Blower
Insufficient airflow is the top reason an AC runs without dropping temperature. Common culprits include dirty filters, matted indoor coils, closed dampers, and weak blower motors.
What to do:
- Replace 1 inch filters every 30 to 60 days in Atlanta’s heavy pollen season.
- Keep 2 feet of clearance around returns and avoid stacking boxes near indoor air handlers.
- Listen for unusual blower sounds like squealing or intermittent surging.
What a pro checks:
- Filter sizing and MERV rating impact on static pressure.
- Evaporator coil cleanliness and temperature drop across the coil.
- Blower wheel balance, speed tap settings, and capacitor health.
If airflow is too low, the coil can freeze. That blocks heat removal and the system may blow warm air even while running.
Low Refrigerant or a Leak
Refrigerant is the lifeblood of your AC. Low charge reduces heat transfer, so the unit runs and runs with little cooling. Signs include long runtimes, warm supply air, hissing at the indoor or outdoor unit, and ice on refrigerant lines.
What to do:
- Do not attempt to add refrigerant yourself. Refrigerant handling requires EPA certification.
- If you see ice, turn cooling Off and run the fan to thaw. This protects the compressor.
What a pro does:
- Finds the leak, repairs it when possible, and weighs in the correct charge.
- Tests superheat or subcool to manufacturer specs.
- Advises on replacement if coils are corroded or the system uses an older refrigerant and repair is not cost effective.
Outdoor Unit Problems: Condenser and Fan
The outdoor condenser must reject heat to the outside air. Dirt, grass clippings, or a stalled fan trap heat in the system.
Symptoms:
- Outdoor fan not spinning or starts then stops.
- Loud humming from the condenser with little or no airflow.
- Hot air at the top of the unit and warm air from indoor vents.
What helps:
- Gently rinse the condenser fins from the inside out after power is off.
- Keep shrubs trimmed at least 18 to 24 inches away.
Pro fixes:
- Replace weak start or run capacitors and test contactors.
- Clean condenser coils and straighten fins for better heat rejection.
Frozen Evaporator Coil
A frozen indoor coil stalls cooling and can overflow the drain when it thaws. Causes include restricted airflow, dirty filters, low refrigerant, weak blower, or closed supply vents.
What to do now:
- Turn the thermostat to Off and Fan to On for several hours to thaw.
- Place a towel near the air handler in case of drips.
- After thawing, try cooling again with a new filter and all vents open.
Call if ice returns. Persistent freeze-ups point to deeper airflow or refrigerant issues that need diagnosis and gauges.
Clogged Condensate Drain or Safety Switch Trip
Your AC removes humidity. That water must drain. Algae in the condensate line can block flow and trip a float switch that shuts cooling while the blower still runs.
What to try:
- Locate the condensate drain near the indoor unit. If there is a cleanout tee, remove the cap and use a small wet-dry vacuum on the outside drain line.
- Pour a cup of diluted white vinegar into the cleanout to slow algae growth.
When to call: If the safety switch keeps tripping or the trap is inaccessible, a technician can flush the line, check the pan, and reroute or rebuild the drain as needed.
Ductwork, Zoning, and Home Insulation Gaps
If only some rooms are warm, the AC may be fine while ducts leak or a zone damper sticks. Attic ducts in Metro Atlanta can reach extreme temperatures, amplifying losses.
What to look for:
- Closed or stuck dampers on round ducts near the trunk lines.
- Kinks in flex duct or crushed runs after attic work.
- Rooms above garages and bonus rooms that never cool well.
Pro solutions:
- Pressure test for leakage and seal with mastic.
- Diagnose zone control boards and actuators.
- Advise on insulation and airflow balancing for even temperatures.
Electrical, Capacitors, and Breakers
Your system can run the indoor fan even when the compressor or condenser fan is down. That produces airflow with no cooling.
Telltales:
- Indoor fan blows, outdoor unit is silent.
- Breaker trips repeatedly.
- A bulged capacitor or burnt contactor.
What to do:
- Reset a tripped breaker once. If it trips again, stop and call.
- Do not open electrical panels on the unit. The risk of shock is real.
Pros test capacitors, contactors, relays, and wiring. Many of these repairs are fast and cost effective.
Age, Sizing, and Extreme Heat
Even a healthy system struggles during heat waves, and an undersized unit may run non-stop without reaching setpoint. If your system is 12 to 15 years old with frequent repairs, replacement can lower energy bills and improve comfort.
How we assess:
- Load calculation to confirm sizing for your home and insulation levels.
- Duct and static pressure review to match new equipment with your duct system.
- Options that balance first cost with long-term savings, including high-efficiency heat pumps and ductless systems.
What Moncrief Technicians Check on Every AC Repair Visit
You deserve a thorough diagnosis, not guesswork. At your appointment, a licensed technician will:
- Verify thermostat operation and low-voltage controls.
- Measure temperature drop across the evaporator coil.
- Inspect the condenser cabinet and coils.
- Test start and run capacitors.
- Check refrigerant level and look for leaks.
- Evaluate blower performance and wiring assemblies.
- Clear or clean the evaporator drain if needed.
- Confirm breakers and fuses are correct and secure.
These steps mirror our in-house tune-up checklist and help prevent repeat failures.
Prevent Breakdowns with Regular Maintenance
Atlanta pollen and heat are tough on AC systems. Our comprehensive AC tune-ups include full inspection, cleaning, and performance checks to keep cooling reliable.
Benefits you feel:
- Lower energy use and steadier temperatures.
- Fewer mid-season breakdowns.
- Cleaner coils and drains for stronger airflow and dehumidification.
For the best protection, consider our Total Comfort Service Plan. You get two annual tune-ups, priority scheduling, and free parts and labor on covered repairs. Many common repairs cost zero with the plan, including fan motors, circuit boards, and thermostats that would normally cost hundreds.
DIY vs Professional: How to Decide
Do these yourself today:
- Replace the filter and clear return grilles.
- Check breakers and thermostat settings.
- Rinse obvious debris from the outdoor unit after power is off.
Call a professional when:
- You see ice on lines or the system short cycles.
- The outdoor unit is silent or the breaker trips again.
- Humidity is high and vents blow warm for more than 20 minutes.
- You suspect a refrigerant leak or clogged condensate system.
Same-day help is available in Atlanta, Sandy Springs, Roswell, Alpharetta, Marietta, and nearby areas.
Real-World Fixes We See in Atlanta Homes
Here are common solutions that restore cooling quickly:
- Unclog and flush condensate lines that trip float switches.
- Replace failed capacitors so the condenser fan and compressor start reliably.
- Clean heavily matted coils to recover the correct temperature drop.
- Repair small refrigerant leaks and recharge to the right level.
- Rebuild or reroute drains and add cleanout tees to prevent future clogs.
- Balance airflow by opening stuck dampers and correcting kinked flex ducts.
These repairs are fast for a trained tech and can return your home to comfort in one visit.
How to Know if Replacement Makes More Sense
Consider replacement when:
- The system is over 12 years old with multiple recent repairs.
- The compressor is failing or parts are obsolete.
- Your electric bills stay high and humidity control is poor.
What you gain:
- Quieter operation and better dehumidification.
- Lower operating costs.
- Warranty coverage and modern controls.

Frequently Asked Questions
Why is my AC running but not cooling enough at night?
Nighttime humidity can be high in Atlanta, which reduces heat transfer. Check filters and vents. If airflow and charge are low, a pro tune-up can restore capacity.
Can a dirty air filter really stop my AC from cooling?
Yes. A clogged 1 inch filter starves the coil of airflow. That can cause freeze-ups and warm air. Replace filters every 30 to 60 days during pollen season.
How long should my AC run to cool a few degrees?
In hot weather, 15 to 20 minutes per degree is common. If it runs much longer with little change, there may be airflow or refrigerant issues.
Is it safe to hose off my outdoor unit?
Power off first. Use gentle water from inside out to remove debris. Avoid bending fins. Deeper cleaning and electrical tests should be left to a pro.
When should I consider replacement instead of repair?
If your system is over 12 years old, needs major parts, or has rising energy bills and comfort issues, a replacement may save money long term.

Roswell, GA AC Installation Time — What Affects It
Estimated Read Time: 12 minutes
If you are asking how long does AC installation take, you are likely sweating a broken system or planning a proactive upgrade. Most standard replacements wrap up in one day, but the real answer depends on your home, equipment choice, and any add‑ons like ductwork or smart controls. In this guide, we outline exact timelines, what speeds things up, what slows them down, and how Moncrief keeps Atlanta installs on schedule. Bonus: ask about our current $1,000 savings on full system installs.
Typical AC Installation Timelines in Metro Atlanta
Most like‑for‑like replacements take 6 to 10 hours from arrival to cool‑air test. That includes safe removal of the old unit, setting and connecting the new equipment, charging the refrigerant to spec, and commissioning.
Here is a quick reference based on thousands of installs in homes across Atlanta, Sandy Springs, Roswell, Alpharetta, and Marietta:
- Split central AC or heat pump, same location, no duct changes: 1 day.
- System changeout with minor electrical or line‑set work: 1 day, sometimes early Day 2 for finishing.
- Add or replace ductwork in part of the home: 1 to 2 days.
- Full duct redesign or conversion from window units to central air: 2 to 3 days.
- Multi‑zone ductless mini‑split with 2 to 4 heads: 1 to 2 days.
- Large multi‑zone ductless (5+ heads) or complex attic/crawl runs: 2 to 3 days.
Why our times are reliable:
- We send an engineer to evaluate the home before install, so there are no day‑of surprises.
- We remove and dispose of the old system, then install your new one to manufacturer specifications.
- You receive text and email updates before the appointment and a heads‑up when the crew is on the way.
What Affects How Long Your AC Installation Takes
Even straightforward replacements vary. These are the biggest timeline drivers we see in Metro Atlanta homes:
- Equipment type and efficiency
- Higher‑efficiency variable‑speed systems often require more commissioning time.
- Heat pumps with communicating thermostats add setup steps compared to single‑stage AC.
- Location and access
- Tight attics in older bungalows, steep roofs, or low crawl spaces slow down safe equipment placement.
- Condenser pad work or relocating the outdoor unit adds time.
- Refrigerant and line sets
- Reusing an existing line set can be faster if it is the right size, leak‑free, and clean.
- New line sets or long vertical runs take longer to fabricate and pressure test.
- Electrical updates
- New disconnects, breakers, or service whips sometimes add one to two hours.
- Ductwork condition
- Leaky, undersized, or moldy ducts harm performance. Repairs or resizing improve comfort but add hours to days.
- Indoor air quality add‑ons
- UV lights, higher‑MERV filtration, and fresh‑air kits add installation steps.
- Controls and smart home integration
- Smart thermostats and app pairing add configuration time and homeowner training.
- Permit and inspection timing
- Many Metro Atlanta jurisdictions require a mechanical permit for replacement systems. Inspections are typically scheduled within a few business days of the installation.
Central Air vs. Heat Pump vs. Ductless: Timeline Differences
Choosing the right system affects both comfort and your schedule.
- Central air conditioner
- Typical timeline: 1 day for a like‑for‑like changeout.
- Notes: Best for homes with existing ducts in good shape.
- Heat pump
- Typical timeline: 1 day, sometimes early Day 2 for commissioning.
- Notes: Provides efficient heating and cooling, popular for year‑round comfort and utility savings.
- Ductless mini‑split
- Typical timeline: 1 to 2 days depending on number of zones.
- Notes: Ideal for additions, sunrooms, finished basements, and homes without ducts. Minimal wall cuts and quick comfort.
In humid Atlanta summers and during heavy spring pollen, ductless units shine because you can zone rooms independently and filter air closer to the source.
The Moncrief Installation Process, Step by Step
Your time matters. Our process removes guesswork and shortens the path to cold air.
- Free on‑site consultation and load evaluation
- An experienced engineer evaluates your home, discusses comfort issues, and matches equipment to your size and budget.
- Transparent proposal and financing options
- You receive upfront pricing, rebates if available, and flexible financing upon approval.
- Scheduling and notifications
- You get an email and text confirmation. On install day, you receive a call and text when the team is on the way.
- Safe removal and site protection
- We carefully remove and dispose of the old system and protect floors and work areas.
- Precise installation to manufacturer specs
- We set the new equipment, braze or connect line sets, pull a vacuum, and charge to spec. As a Trane Authorized Dealer, we follow strict commissioning steps.
- Duct, airflow, and safety checks
- We verify airflow and temperature split, inspect electrical connections, and confirm condensate drainage.
- Thermostat setup and homeowner walkthrough
- We connect and program your thermostat, show you the app, and review filter changes and best practices.
- Post‑install follow‑up and one‑year maintenance plan
- All new installs include equipment warranties and a complimentary one‑year maintenance plan. We schedule tune‑ups and check in after the job.
How to Keep Your Install to One Day
Follow these tips to shorten timeline risk and avoid rescheduling in busy season:
- Finalize your equipment choice before the crew arrives so materials are staged.
- Clear a 3‑ to 4‑foot path to the indoor unit, attic access, and electrical panel.
- Move cars for driveway or curb access to speed unloading.
- Confirm thermostat location and Wi‑Fi password if pairing a smart stat.
- Tell us about any recent electrical or remodel work so we can prep permits and materials.
- Consider duct repairs now rather than later. Fixing airflow on install day prevents callbacks and discomfort.
When Installations Take Longer Than a Day
There are good reasons to invest extra time:
- Major duct upgrades
- If rooms are hot upstairs or stuffy over garages, undersized returns or leaky boots are common. A small duct redesign can transform comfort and noise.
- System relocation
- Moving air handlers out of tight crawl spaces can boost serviceability and reduce future labor costs.
- Complex homes and historic properties
- In older craftsman homes or renovated spaces, matching equipment to unique layouts and insulation levels takes more planning and precision.
- Multi‑zone ductless
- Running lines to several rooms and setting multiple indoor heads is precise work worth doing right.
Longer installs do not mean delays in comfort. We stage temporary cooling options when needed and plan multi‑day work to minimize disruption.
What We Check Before We Leave
A fast install is good. A correctly commissioned system is better. Our crews complete a detailed checklist so your new AC performs on day one and year five:
- Refrigerant levels, superheat, and subcool targets matched to manufacturer data.
- Static pressure and airflow verified across the system.
- Thermostat calibration and mode testing for cool, heat, and fan.
- Safety checks on electrical, drain pan float switches, and condensate flow.
- Clean work area, old system hauled away, and a homeowner orientation.
These steps are why many homeowners notice quieter operation, faster cooldowns, and lower humidity after upgrade.
Post‑Install: How Maintenance Protects Your Time and System
The first year is on us. Your complimentary one‑year maintenance plan includes a seasonal tune‑up with full system inspection, cleaning, airflow and safety checks, and performance adjustments. Staying on schedule protects warranties and reduces surprise downtime in July heat.
Our Total Comfort Service Plan options can extend coverage with twice‑yearly tune‑ups, priority scheduling, guaranteed same‑day service, and plans that include parts and labor. If something goes wrong, you are first in line and covered per plan terms.
Local Factors Atlanta Homeowners Should Know
- Summer heat and humidity
- Expect crews to start early to beat midday attic temperatures. Good planning avoids heat‑related delays.
- Pollen season
- Spring tree pollen can coat coils and filters. We protect equipment during install and advise on filter upgrades.
- Permits and inspections
- Local jurisdictions across Fulton, DeKalb, Cobb, and Gwinnett typically require a mechanical permit for replacements. We handle the paperwork and coordinate inspections.
- Home styles
- From mid‑century ranches in Sandy Springs to brick two‑stories in Alpharetta and crawl spaces in Marietta, access and duct layouts vary. We tailor timelines to fit your home.
Signs Your Install Was Done Right
- Even temperatures room to room, with strong airflow.
- Quiet starts and stops without harsh bursts of air.
- Thermostat holds set point without long run times.
- Humidity control improves, especially on muggy days.
- Utility bills trend down compared to your old system.
If you do not experience this, call us. Our priority support resolves issues quickly, and maintenance customers receive guaranteed same‑day service.

Yes—water filtration systems need regular maintenance to keep water quality high and flow steady. The most common task is replacing or cleaning prefilters and carbon media as they load up with sediment and captured chemicals. Many systems also benefit from periodic sanitizing of housings, flushing of tanks, and a quick check of valves, fittings, and leak detectors. A simple before-and-after pressure check across the filter can reveal clogging long before you taste a change. Our licensed plumbers service these systems across the Atlanta area, including homes in Canton.
Watch for these signs it’s time for service:
- Drop in water pressure at several fixtures
- Taste or odor returning after clear improvement
- Cloudy water or fine grit collecting in sinks
- Filter housing discoloration or any moisture at fittings
If you’re unsure of the right interval for your system, book a quick inspection and water test before problems build.

Drain cleaning for a clogged drain is priced after an on‑site diagnosis, and Moncrief provides upfront pricing before any work begins. Most clogs are simple obstructions near the fixture, but costs rise when the blockage is deeper in the line or the main sewer is involved. If the repair totals over $250, you can use our $50 OFF emergency repair offer (must mention when scheduling; expires 11/30/2025; not valid with other offers or prior services). We handle clogged drains for homeowners in and around Kennesaw every day.
What most affects price:
- Multiple fixtures backing up usually means a main‑line clearance, not a simple trap clean.
- Tooling needed (hand auger vs larger machine or hydro‑jetting) and any camera inspection.
- Access challenges, such as no outdoor cleanout or work in a crawlspace/roof vent.
- After‑hours or weekend emergency timing.
Shut off water to the affected fixture and avoid chemical drain cleaners until a tech inspects the line.

There isn’t a single universal “most common” AC repair, but technicians most often fix wear‑and‑tear electrical parts, airflow blockages, or drainage problems that shut the system down. The usual cause is age and heat stress on components, followed by dirt buildup that restricts cooling.
Common repairs we handle include:
- Replacing start/run capacitors when the outdoor fan or compressor won’t start
- Clearing a clogged condensate drain to stop leaks and AC shutdowns
- Restoring proper thermostat control when the system short cycles or won’t cool
- Repairing blower issues or addressing low refrigerant after finding and fixing a leak
Our North Metro team sees these across central ACs, heat pumps, and ductless systems, and a quick diagnostic visit confirms the exact fix before any work begins. A humming outdoor unit with a non‑spinning fan often points to a weak capacitor rather than a failed motor.
If you notice warm air, water around the indoor unit, or repeated shutdowns, turn the system off and schedule a professional diagnosis.

The most common slab leak symptoms in a home are unexplained water use, warm or damp flooring, and the sound of running water when all fixtures are off. Most people first notice a higher water bill or a warm spot on the floor from a hot‑water line under the slab. A slab leak is a pressurized water line leaking beneath the concrete, and it can wash out soil, loosen flooring, and invite mold if ignored. Our licensed and insured technicians routinely address these issues for homes in and around Alpharet.
Watch for these specific signs:
- Sudden spike in your water bill or a water meter that moves with all fixtures off
- Warm spots on tile or hardwood, damp carpet, or musty odors
- Hearing water running inside walls or under floors
- New foundation cracks or a small area of floor lifting
If you suspect a slab leak, shut off the main water valve and avoid using electrical appliances near wet areas.
