Consumer Comments for GAC Services

Consumer from POTOMAC, MD

This was for a maintenance visit. I believe that everything was performed properly, but the digital report which I received was not completed nearly as thoroughly as past GAC technicians have done. Tech was well-versed in his trade but had difficulty communicating the information to us. (He was a native English speaker.) The prices for suggested repairs seemed quite high, but the tech did not push to do them on this older system.

Consumer from ROCKVILLE, MD
Jun 11, 2026

High prices for all tasks. THey are 50-100% higher. Wanted almost $900 to install a thermostat.

Do not use for geothermal services. The people are nice, but not technically trained only learned by on - the- job.

What to Do If You Need HVAC Repairs

If you need repairs to heating or air-conditioning equipment, our ratings of local businesses will help you find a good company to perform them.

Choosing New HVAC Equipment and Getting It Installed Properly

How well a new HVAC system performs, and how much it costs, depends heavily on its design and the quality of installation. It’s important to make the right decisions—and there are many to make. You also must make sure to get a fair contract.

HVAC Equipment Features to Consider

If you are installing new equipment, in addition to making choices about energy efficiency, you will need to decide whether to pay extra for various features. Here is a summary of the types of add-ons.

Maintaining Your HVAC Equipment

The most important maintenance task for HVAC systems is something you can do yourself—replacing the air filter. Check your filter monthly. When a filter has a matting of dirt—i.e., it’s difficult to see through when you hold it up to a light—it’s time to replace it.

HVAC Maintenance Contracts Are Usually Bad Buys

Rather than paying for individual maintenance visits and repair jobs, you might consider getting a service contract for air-conditioning and/or heating equipment. Many companies try to persuade customers to enter into such contracts.
