Call (361) 317-6400 and we will tell you current availability. During July and August, every HVAC company in Collin County gets slammed with calls at the same time. The sooner you call after noticing a problem, the better your chances of getting seen quickly. Do not wait until the unit fully dies.

The most common causes are low refrigerant, a dirty evaporator coil, or a failing compressor. In McKinney, dirty coils are very common because the air here carries a lot of dust and pollen in spring. Running the unit continuously without cooling can make the damage worse. Get it looked at before it turns into a bigger repair.

Routine repairs like capacitor or contactor replacements generally do not need a permit in McKinney. Larger work like replacing a compressor or the refrigerant line set may require one depending on scope. A contractor who skips permits on work that requires them is cutting a corner that can cause problems if you sell the house.

Warm air from the vents, strange noises from the outdoor unit, ice on the refrigerant lines, and the unit short-cycling are all warning signs. A lot of homes in Eldorado Parkway and the older parts of McKinney have units that are 15 to 20 years old. At that age, these signs usually mean a part is close to failing.

If the unit is under 10 years old and only one part failed, repair usually makes sense. If it is 15 or more years old and the compressor is gone, replacement often costs less over the next 5 years than keeping the old system alive. We will give you an honest read on which way to go after we inspect it.
