Heating Installation in Locust Grove, GA

If you are replacing heat in Locust Grove, there is a fair chance it is the builder’s original heat pump. That makes this a chance to fix the first decision instead of repeating it.

Installing heat at the fast-growing end of Henry County

A lot of Locust Grove is new build, and new build gets the system that met code at the lowest price on the day the house was signed off. It heats. It heats until the day it does not, and then you find out it was never sized for the rooms you use or the windows that face west.

The replacement can correct that. We will tell you what the house needs, what that costs, and what you would be paying extra for that you would never notice. We are fifteen minutes up I-75 when you want to talk it through.

Ask what the ductwork is doing. In new build the duct is usually where the budget went to die — undersized returns, flex with a kink folded in. Replace the equipment and leave that in place and you have bought a better box with all the same cold-room complaints. Now and then the honest fix is a duct modification, not a bigger unit.

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
