Recommended Customer Reviews

quick response. couple hours and a capacitor was replaced and back to cooling on a really hot day. $270 that included service call. not cheap, I know, but in line with other companies. serviceman , Timmothy, was polite and knowledgeable. would call again.

We requested a quote from United, and the technician was extremely rude. When he found out we had requested quotes from multiple companies in order to shop for the best price, he quite literally walked off the job. Awful customer service!

If you want to be scammed then this is the place for you! I had my unit serviced on Feb 2019 and was told the reason why my unit wasn't coming on was due to my motor fan needing to be replaced. I paid the $1600 for the new fan and two weeks later I was without AC. I called United since my fan was covered under a 1 year service warranty. United sent the same tech out and he proceeded to lie and tell me that it wasn't my motor but It had a leak instead! The gentleman had looked at my outside unit countless times! So how do you miss a leak?? Once the tech tells me it would be ANOTHER $1500 for a new line I was done. I told the tech I wasn't interested in anymore dealings with United , so he starts to offer a jug of Freon for $200 to make me feel better. What's the point of adding Freon if I have a leak? I Just had to purchase a new unit so I'm beyond pissed after paying almost $2000 to fix the old unit .... AVOID AVOID AVOID!

Still hot! Came out for a service call, charged $300 for freon, which 24 hours later again it's 79 degrees in the house. Call united back and guess what? There is a leak, which they still haven't found. They are wanting to charge again for Freon because it all leaked out, which it wouldn't have if they would have investigated the complaint the first time and found the leak prior to putting gas in it! Scam company, do not let them just place gas in without first proving they have fixed the leak. I'm so mad, and STILL HOT!

alert! alert! do not hire united heating & air in montgomery al!! if you do you would be very sorry!! two months ago they came to my house to replace a new coil at the attic, and they charged us more than double of the price (even though it was a free replacement unit under manufacture warranty) as compared to the price of other companies in town. two months later, the same ac unit was not cooling again, we got them back to diagnose the problem,. this time they said they found the outside unit was leaking and it cannot be repaired, and we must replace the entire unit for a quoted price between $4350 and $5,600. however, we had another ac and heating company's diagnosis and that it can be repaired at a minimal cost as opposed to united heating pricing. i was sad and truly feel that we have been ripped off by united heating & air despite we are their long time loyal customer in the last 4 years.
