AC Repair FAQ — Lewisville, TX

It depends on what broke. Replacing a capacitor is a short job with an inexpensive part. Tracking down a refrigerant leak or replacing a contactor takes longer and costs more. A failing compressor on a unit that is more than 12 years old may not be worth repairing at all. Every job is looked at first. Call for a free estimate.

Most common repairs — capacitors, contactors, clogged drain lines, dirty coils — are done in one visit that takes one to two hours. Refrigerant leaks take longer because we have to find the leak before we can fix it. If a part has to be ordered, we will tell you upfront so you can plan.

A frozen AC coil usually means low refrigerant, a dirty air filter, or a blower that is not moving enough air. In Lewisville, heavy dust and pollen from spring storms clog filters faster than people expect. Shut the system off and let it thaw for a few hours, then call us — running it frozen can burn out the compressor.

Warm air usually points to one of four things: a failed capacitor, a refrigerant leak, a dirty condenser coil, or a thermostat problem. The condenser sits outside and takes a beating from summer heat in North Texas — coils caked with cottonwood or grass clippings cannot release heat properly. A quick inspection will narrow it down.

Minor repairs like replacing a capacitor or cleaning a coil do not need a permit. Work that involves changing out refrigerant lines, replacing a full system, or modifying ductwork typically does require one through the City of Lewisville. Any contractor who skips a required permit is putting that liability on you as the homeowner.

A rough guideline: if the repair costs more than half of what a new unit would cost, and the system is already 12 to 15 years old, replacing it often makes more sense. A lot of the original equipment installed in Lewisville subdivisions built in the late 1980s and 1990s is at that age right now. We will give you a straight answer on which direction makes sense after we look at it.
