How much does AC repair cost in Lubbock?

Most AC repairs in Lubbock range from $150 to $750 depending on the part. Major repairs (compressor, evaporator coil) run higher. We give you an exact flat-rate price before we start. Call Armstrong at (806) 763-2665.

Why is my AC running but not cooling?

Common causes: low refrigerant from a leak, a frozen evaporator coil, a failed compressor, or a dirty condenser. Our techs diagnose the real cause — not just top off refrigerant and leave.

Should I repair or replace my AC unit?

Rule of thumb: if your unit is under 10 years old, repair. If it's 12+ years old and the repair is over $1,500, replacement usually makes more financial sense.

Do you offer same-day AC repair in Lubbock?

Yes. We dispatch same-day in most cases and offer 24/7 emergency AC repair. Call Armstrong at (806) 763-2665.

Why is my AC short-cycling?

Short-cycling is usually caused by an oversized unit, a dirty filter, low refrigerant, or a failing thermostat. It wastes electricity and burns out the compressor — get it looked at quickly.
