Clear answers. The right repair.

We find the cause.

Blowing warm air? Leaking water? Making a noise it never made before? We repair air conditioners for homeowners in Roanoke and the towns around it.

We will find out what is wrong, tell you what it takes to fix it, and get your house cool again.

We fix what caused the problem. Otherwise it breaks again.

Professional diagnostics

We test it before we quote it.

An AC can stop cooling for a dozen different reasons. So we test before we quote. Here is what we look at:

  • Refrigerant pressures
  • Supply and return air temperatures
  • Capacitors and contactors
  • Voltage and electrical connections
  • Blower and fan motors
  • Evaporator and outdoor coils
  • Air filters
  • Condensate drains and float switches
  • Thermostats and control boards
  • System error codes

We have found systems shut down by nothing more than a clogged drain tripping a safety switch. Compressors that would not start because of a bad capacitor. Blown fuses traced back to a sensor wire that rubbed through against the metal cabinet.

Common service calls

Common AC problems we repair in Roanoke.

AC Not Cooling or Blowing Warm Air

Most often it is low refrigerant, a dirty coil, or a blocked filter. Sometimes it is the capacitor or the compressor. We check how the system is running before we tell you what it needs.

AC Will Not Turn On

We test the capacitor, the contactor, the fuses, and the float switch. One of those four is usually the answer.

Water Leaking From Your AC

We clear the drain, check the pan and the line, and make sure the water runs off the way it should.

Low Refrigerant or Refrigerant Leaks

Low refrigerant means a leak. We check the pressures and look for where it is going out.

Frozen AC Coils

A frozen coil is a symptom, not the problem. Usually it is airflow or refrigerant. We find out which one.

Blower, Fan, and Motor Problems

We check the voltage, the capacitor, and the wiring before we call a motor bad. Motors are expensive to guess at.

Electrical, Capacitor, and Control Problems

These are the parts that fail most and cost the least to fix. We test them first.
