AC Installation in Jonesboro, GA
Older Jonesboro houses do not always take a modern system straight out of the box. We are about twenty minutes east of you, over in Henry County.
Replacing an older Jonesboro system
Established housing was built around whatever was normal at the time — smaller returns, longer duct runs, and sometimes an equipment footprint a modern unit simply does not drop into. Pretending otherwise is exactly how somebody ends up with an expensive new system that performs precisely as badly as the old one did, and nobody can work out why.
We would much rather find that on the quote than on install day, with your ceiling open. That means looking at the ducts and the returns and not just the box outside, and telling you honestly if the real answer is more work than a straight swap. It is a worse sales pitch and a much better outcome.
The other thing worth raising early is the electrical. An older house may have a service and a disconnect sized for the equipment of its day, and a modern system does not always match what is already there. That is not a reason to avoid the job — it is a reason to find it during the quote, because "we will sort that out on the day" is precisely how a one-day install turns into a three-day one with an electrician wedged into the middle of it.
When replacing really is the answer
- The compressor is gone and the unit is well past ten years old
- It needs refrigerant every single season
- The repair quote is a serious fraction of a new system
- Upstairs never cools, whatever the thermostat says
- It’s loud, it’s tired, and it costs a fortune to run

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
