Residential AC Repair Services in Midland, TX
From the $30 capacitor that quietly kills your compressor to a full refrigerant leak repair, GenMech HVAC handles every kind of residential AC failure across Midland and the surrounding Permian Basin.
AC Not Cooling or Weak Cooling
When the AC runs but the house won’t cool, the cause is usually low refrigerant, a failing compressor, or restricted airflow. We diagnose the root cause, not just the symptom.
- Refrigerant pressure check
- Compressor diagnostics
- Airflow & coil inspection
- Capacitor & contactor testing
Refrigerant Leak Detection & Recharge
Low refrigerant means a leak somewhere in the system. We find it with electronic leak detectors and UV dye, repair the leak, and recharge to factory specs. .
- Electronic leak detection
- UV dye tracing
- Line set inspection
- EPA-certified recharge
Compressor & Condenser Repair
The compressor is the heart of your AC. When it fails, repair vs replace is a real conversation. We give you the numbers and let you decide.
- Compressor diagnostics
- Condenser fan motor
- Hard-start kits
- Capacitor replacement
Evaporator Coil & Frozen Coil Repair
Ice on the indoor coil or refrigerant line means airflow or refrigerant trouble. Running the AC frozen damages the compressor, so call before the ice spreads.
- Frozen coil thaw & diagnosis
- Coil cleaning
- Drain line clearing
- Airflow restoration
Thermostat Diagnostics & Replacement
A thermostat that lies to your AC will run up your bill or leave you uncomfortable. We test, calibrate, or replace with a model that matches your system.
- Smart thermostat install
- Wiring & low-voltage repair
- Sensor calibration
- Compatibility check
Capacitor, Contactor & Electrical Repair
Most “AC won’t start” calls come down to a $30 capacitor or a worn contactor. We carry common parts on the truck so most calls finish same visit.
- Capacitor replacement
- Contactor service
- Wiring inspection
- Disconnect & breaker checks
Signs Your AC Needs Service
Most AC failures give you a warning before they leave you in a hot house. If you see any of these signs, call sooner rather than later. Small repairs are always cheaper than emergency ones.
AC blowing warm air. Often refrigerant loss, a failing compressor, or a frozen evaporator coil. The system runs, but warm air comes out of the vents.
Loud or unusual noises. Banging, hissing, or screeching point to loose components, a refrigerant leak, or motor bearing failure. None of these get better on their own.
Ice on the indoor unit or refrigerant line. A frozen system is working against itself. Shut it off and call. Running it frozen risks compressor damage that turns a small repair into a major one.
AC short-cycling. Turning on and off every couple of minutes wears out the compressor and signals thermostat trouble, refrigerant issues, or an oversized system.
Water pooling around the indoor unit. A clogged condensate drain or cracked drain pan can flood floors and ceilings. Easy fix when caught early.
Energy bill jumped without a lifestyle change. A sudden spike usually means your system is working harder due to a failing component, dirty coils, or a refrigerant leak.
