What does AC repair involve?
AC repair covers everything from refrigerant recharges and capacitor replacements to compressor rebuilds and full system diagnostics. Whether it's a central air system, a window unit, or a ductless mini split, if it's not cooling, we fix it.
A failing AC system doesn't just make you uncomfortable. It drives up energy bills, puts stress on your electrical system, and can lead to humidity problems that cause mold growth and structural damage to your home.
Our Western Mass technicians service all major brands including Carrier, Lennox, Trane, Goodman, Rheem, Mitsubishi, and Daikin. We handle both residential and light commercial systems, from newer high-efficiency units to older R-22 systems that need careful attention.
Common AC repairs include replacing capacitors, contactors, fan motors, and compressors. We also handle refrigerant leak detection and repair, electrical troubleshooting, thermostat issues, and frozen evaporator coils.
Signs your AC needs repair
Warm air blowing from vents
If your AC is running but pushing warm or room-temperature air, you could have a refrigerant leak, compressor failure, or a problem with your ductwork. This won't fix itself and usually gets worse.
Weak or reduced airflow
Noticeably less air coming from your vents often points to a clogged filter, blocked ducts, or a failing blower motor. Restricted airflow forces your system to work harder, driving up energy costs.
Unusual noises or vibrations
Grinding, squealing, banging, or buzzing sounds are never normal. They usually indicate loose components, worn bearings, or a failing compressor. Catching these early prevents bigger, more expensive failures.
Water leaking around the unit
Pooling water near your indoor unit typically means a clogged condensate drain line or a frozen evaporator coil that's thawing. Left unaddressed, water damage to floors and walls adds up fast.
Bad odors when the AC runs
Musty or moldy smells suggest biological growth in your ducts or on the evaporator coil. A burning or electrical smell needs immediate attention and likely means a wiring issue or overheating component.
System running constantly without cooling
An AC that never shuts off but can't reach the set temperature is working overtime for nothing. This could be low refrigerant, a dirty condenser coil, or an undersized system struggling in extreme heat.
