Heating Installation in Fayetteville, GA

Fayetteville heating installs split between correcting builder-grade heat pumps and fitting modern equipment into older Fayette County houses. We are about 25 minutes east.

New heat, two Fayetteville problems

In the newer subdivisions the original heat pump is often the same box the builder put on every lot that month. It meets code. It does not necessarily meet the upstairs, the west glass, or how you actually live in the house. The replacement can correct that instead of cloning it.

On older Fayetteville streets the problem is fit: returns, electrical, a furnace closet that was framed around a different machine. We would rather say “this is more than a swap” on the quote than discover it with the old unit already on the truck.

Either way: diagnose the house, quote the system it needs, stay nearby when year three has a question. Twenty-five minutes from Stockbridge is local enough that the relationship is the product, not just the cabinet.

When a new heating system is the honest call

  • The heat pump compressor is gone and the unit is well past ten years old
  • Emergency heat has been carrying the house and the bill shows it
  • The furnace heat exchanger is cracked or the cabinet is rusting through
  • It needs a major repair every winter
  • One floor never gets warm, no matter what the thermostat says

McGrath Mechanical is my go to choice for HVAC repairs and installation. As a property manager of properties all over the Atlanta area, I need a reliable HVAC source that will show up, diagnose the problem correctly, tell me the truth and make the repair at a reasonable cost. McGrath does exactly that! New system installations are efficient and affordable as well. I highly recommend James at McGrath Mechanical!

If he says he will be there then he will. James is fast, reliable, and gets the job done. I thought I needed a new unit but that wasn’t the problem. After about 30 minutes he had us up and running again. Any questions I had he was able to give me an answer. Highly recommend
