GMC Air Conditioning Services, LLC

Most critical

I scheduled a maintenance service to clean 4 mini-split units, and they clearly had no idea how to manage even a basic appointment. I called four times just to confirm, and each time it felt like no one knew who was handling my request. Despite that, they never showed up on the scheduled day.

We rescheduled for the next day at 10 AM, but instead the technician randomly showed up at 8:30 AM when I wasn’t even home. Completely unprofessional and disrespectful of agreed timing.

When the work was finally done, it was extremely poor quality. They claimed they would:
• Cover walls to prevent damage
• Properly clean and spray the indoor units
• Clean and flush after spray

None of that was done properly. The technician barely used half a bottle of cleaner across all 4 units, clearly just going through the motions. For the outdoor units, he simply sprayed them with a hose and left, no real cleaning, no attention to detail, and no cleanup afterward.

Only took 40 minutes to clean 4 units ? How's that even possible – terrible job.

I ended up buying a $30 cleaning kit online and did a far better job myself.

To make things worse, I called to complain and was told they’d follow up, but of course, no one ever got back to me.

This company is disorganized, unprofessional, and delivers subpar work. Save yourself the time, money, and frustration, avoid them completely.

Do not rush to use this company or leave a good review!
GMC air company installed my AC 3 years ago and did not finish their contract! Got paid and ran. They will not return my phone calls or do what they were suppose to do, they have very convenient way to avoid you.
You will discover it years later! Be aware. Will be filing complaints and lawsuit.

I won’t recommend this company. Air handler/fan in my 7 years old Carrier’s 2.5 ton a/c was malfunctioning, stopping sometimes for a day but I spent a month to convince GMC that it was a problem. The replacement cost me over $600 after all discounts applied but they installed another old module, not a new part or at least I cannot see new part. However that’s just start of story. UV light stopped working 1 day after this service. GMC offered bulb replacement for $300+ without coming to check. I checked on the issue myself. They incorrectly connected UV light ballast to 240 volts instead of 208 as specified and it fried the ballast, mot the bulb! I admit that the color of hot wires for 240 and 208 was almost similar, red and orange but still why not to check? When I fixed the issue and asked for reimbursement for parts only I got only mile long emails. GMC was original installer of this a/c and UV. I stand for quality of my own service in my business and expect the same from others. But this company doesn’t care. They also try to sell unnecessary replacements. I had two maintenance services from them in span of one year and each time got different recommendations on $200-300 replacements. I don’t trust this company.
