Professional Air Conditioning Repair in Dunwoody, GA

Your AC is running but the house is not cooling in Dunwoody. Or it is turning on and off every few minutes without ever getting the temperature down in Dunwoody, GA. Or it stopped running entirely during the hottest stretch of summer and the temperature inside is already climbing in Dunwoody. Whatever the specific symptom, you need the problem identified and fixed today in Dunwoody, GA.

The urgency with AC problems is that most of them get worse with every hour the system operates with the underlying fault in place in Dunwoody. A refrigerant leak that is causing the system to run without reaching setpoint is continuing to lose refrigerant with every operating hour in Dunwoody, GA. A compressor working against low refrigerant is accumulating wear at an accelerated rate that shortens whatever remains of its service life in Dunwoody. A frozen evaporator coil from restricted airflow is building ice that will eventually shut the system down completely if the restriction is not addressed in Dunwoody, GA. An AC symptom that is merely uncomfortable today can become a complete and more expensive system failure by tomorrow in Dunwoody.

Addressing the specific fault when it first produces a symptom is always less expensive than addressing the compounded damage it produces when left to develop in Dunwoody.

MBM diagnoses and repairs air conditioning systems same-day throughout Dunwoody, GA in Dunwoody. Complete system diagnosis before any repair is recommended in Dunwoody, GA. The specific fault identified and explained clearly before any work begins in Dunwoody. Upfront pricing confirmed before the repair starts in Dunwoody, GA. Correct repair with correct parts. System performance verified before we leave in Dunwoody. Call now, we answer fast in Dunwoody, GA.

Why AC Problems Get Worse With Every Hour in Dunwoody, GA

Every major AC failure mode is progressive in Dunwoody. Refrigerant leaks out continuously in Dunwoody, GA. A failing capacitor produces thermal stress on the compressor with every startup attempt in Dunwoody. A frozen coil builds more ice with every operating cycle in Dunwoody, GA. And a compressor working under any abnormal condition accumulates wear faster than under correct operating conditions in Dunwoody. The fault that produces a moderate symptom today produces a more severe symptom and more expensive damage tomorrow in Dunwoody, GA.

Common AC Problems We Fix

Common AC Problems MBM Diagnoses and Repairs in Dunwoody, GA

AC Not Cooling or Blowing Warm Air in Dunwoody

An AC running but blowing warm or room-temperature air has a specific failure in the refrigerant circuit or condenser in Dunwoody, GA. Low refrigerant from a leak is the most common cause in Dunwoody. A failed condenser fan allowing the coil to overheat is another common cause in Dunwoody, GA. A failed compressor is a less common but more significant cause in Dunwoody.

AC Running Constantly Without Reaching Setpoint in Dunwoody, GA

A system running continuously without reaching thermostat setpoint has a cooling capacity problem in Dunwoody. Low refrigerant reducing capacity. A dirty condenser coil reducing efficiency. An undersized system. Or an air distribution problem preventing conditioned air from reaching the thermostat location in Dunwoody, GA.

AC Short Cycling — Turning On and Off Every Few Minutes in Dunwoody

A failing capacitor that cannot sustain the compressor through a full cycle in Dunwoody, GA. An oversized system that cools the thermostat before the rest of the home reaches setpoint in Dunwoody. A refrigerant charge that is incorrect causing safety switches to trip. Or a dirty filter causing the evaporator coil to freeze and trigger freeze protection in Dunwoody, GA.

AC Not Starting at All in Dunwoody, GA

A specific electrical or control fault preventing startup in Dunwoody. Failed capacitor. Tripped breaker. Failed contactor. Failed control board. Thermostat wiring fault in Dunwoody, GA. MBM diagnoses no-start conditions beginning with the most common and least expensive causes in Dunwoody.

AC Making Unusual Noises in Dunwoody

Grinding or squealing from the air handler indicates a failing blower motor bearing in Dunwoody, GA. Rattling from the outdoor unit may indicate debris or a loose component in Dunwoody. Banging or clanking from the compressor indicates an internal compressor fault in Dunwoody, GA. Bubbling or hissing indicates refrigerant escaping through a leak in Dunwoody.

AC Leaking Water in Dunwoody, GA

Water leaking from the indoor air handler typically indicates a clogged condensate drain line in Dunwoody. A clogged drain causes the condensate pan to overflow, producing water damage to the surrounding structure in Dunwoody, GA. MBM clears clogged condensate drains and treats the drain line with biocide to prevent rapid reoccurrence in Dunwoody.

AC Freezing Up in Dunwoody

A frozen evaporator coil indicates either restricted airflow or low refrigerant in Dunwoody, GA. A frozen coil should not be forced to operate. Turn the system to fan-only mode to allow the ice to melt before MBM's technician diagnoses and addresses the underlying cause in Dunwoody. Do not try to chip or break the ice off the coil in Dunwoody, GA.

What Causes AC Failures

What Causes AC Systems to Fail in Dunwoody, GA

Refrigerant Leaks and Low Charge in Dunwoody

Refrigerant does not deplete under normal operation in Dunwoody, GA. Low refrigerant indicates a leak in the refrigerant circuit in Dunwoody. The leak must be found and repaired before refrigerant is added, or the added refrigerant leaks out and the problem recurs in Dunwoody, GA.

Dirty or Blocked Condenser Coils in Dunwoody, GA

A condenser coil coated in dirt and debris reduces its ability to reject heat in Dunwoody. The system runs at elevated head pressure, reducing efficiency and increasing compressor wear in Dunwoody, GA. MBM cleans condenser coils using appropriate products that restore performance without damaging the coil fins in Dunwoody.

Failed Capacitors and Contactors in Dunwoody

Capacitors provide the electrical boost that starts the compressor and condenser fan motor in Dunwoody, GA. A failing or failed capacitor causes the compressor or fan to struggle to start or fail to start entirely in Dunwoody. Capacitor failure is one of the most common AC repair situations in Dunwoody, GA.

Compressor Failure in Dunwoody, GA

The compressor is the most expensive single component in the AC system in Dunwoody. Compressor failure typically results from long-term operation under abnormal conditions including low refrigerant, dirty condenser coils, or failed capacitors in Dunwoody, GA. A failed compressor requires replacement in Dunwoody.

Electrical and Control Board Faults in Dunwoody

Modern AC systems rely on electronic control boards that manage compressor staging, fan operation, and safety shutdowns in Dunwoody, GA. A failed control board can produce a wide range of symptoms depending on which function it was managing in Dunwoody.

Clogged Condensate Drain Line in Dunwoody, GA

The drain pan and line accumulate algae, mold, and debris that eventually produces a blockage in Dunwoody. A clogged condensate drain causes the pan to overflow and water to leak from the air handler in Dunwoody, GA. MBM clears clogged drains and treats the line to prevent rapid reoccurrence in Dunwoody.

FAQ

Air Conditioning Repair FAQs in Dunwoody, GA

The most common causes in Dunwoody are low refrigerant from a leak reducing cooling capacity, a dirty condenser coil reducing heat rejection efficiency, and a failed condenser fan motor allowing the condenser to overheat in Dunwoody, GA. A compressor that is operating but not pumping refrigerant efficiently is a less common but more significant cause in Dunwoody.
A frozen evaporator coil indicates either restricted airflow preventing adequate heat exchange at the coil or low refrigerant causing the coil temperature to drop below freezing in Dunwoody. Turn the system to fan-only mode to allow the ice to melt before calling for service in Dunwoody, GA. Do not try to chip or break the ice off the coil in Dunwoody.
Short cycling has several possible causes in Dunwoody including a failing capacitor, a refrigerant charge that is incorrect causing safety switch trips, a frozen evaporator coil triggering freeze protection shutdown, and an oversized system that satisfies the thermostat before completing a full cooling cycle in Dunwoody, GA.
Indicators of low refrigerant in Dunwoody include the system running continuously without reaching setpoint, warm air from supply registers, ice on the refrigerant lines near the air handler, and hissing sounds from the refrigerant circuit in Dunwoody, GA. Refrigerant level can only be reliably assessed with pressure gauges connected to the refrigerant circuit in Dunwoody.
A capacitor provides the high-voltage boost needed to start the compressor and condenser fan motors in Dunwoody. A failing capacitor causes the motors to struggle to start, producing a humming sound and excessive heat in the motor in Dunwoody, GA. A failed capacitor causes the motor to fail to start entirely in Dunwoody.
Water dripping from the indoor air handler typically indicates a clogged condensate drain line in Dunwoody. The condensate pan overflows when the drain cannot remove the water the evaporator coil is extracting from the air in Dunwoody, GA. A cracked or damaged condensate pan is a less common cause in Dunwoody.
Most common AC repairs including capacitor replacement, contactor replacement, and condensate drain clearing take one to two hours in Dunwoody. More complex repairs including refrigerant leak location and repair, control board replacement, and evaporator coil replacement take two to four hours or more in Dunwoody, GA.
It depends on the specific noise in Dunwoody. A mild rattling or vibration may be safe to operate temporarily while repair is arranged in Dunwoody, GA. A grinding, banging, or clanking sound from the compressor indicates an internal mechanical fault that can cause rapid compressor failure if continued in Dunwoody. A hissing sound indicating a refrigerant leak should prompt stopping the system and calling for service in Dunwoody, GA.
There is no absolute age cutoff in Dunwoody. The decision depends on the repair cost, the system's age, and its overall condition in Dunwoody, GA. If the repair cost exceeds 50 percent of the cost of a comparable new system and the existing system is more than 10 to 12 years old, replacement warrants serious consideration in Dunwoody.
Yes. A severely restricted air filter reduces the airflow through the evaporator coil below the minimum needed for correct operation in Dunwoody. The coil drops below freezing and ice builds on the coil surface in Dunwoody, GA. The ice buildup progressively blocks all airflow and eventually causes the system to shut down completely in Dunwoody.
Air conditioning repair costs in Dunwoody range from $100 to $350 for minor repairs including condensate drain clearing and capacitor replacement, $300 to $700 for moderate repairs, and $800 to $2,500 and above for major repairs including evaporator coil and compressor replacement in Dunwoody, GA. All pricing confirmed upfront before work begins in Dunwoody.
Yes. Every MBM air conditioning repair is guaranteed in Dunwoody. If the repair does not produce the expected result within the guarantee period, we return and address it at no additional charge in Dunwoody, GA.
