I wanted to clean my evaporator coil. They sent someone for inspection and quote promptly.

What can be improved is implementing some training on teaching their techs not to go ahead and speak with city inspectors without the approval of the owner of the building. I had a tech go ahead and speak with the inspector out of turn on a project he has no clue about or background knowledge and now has caused additional headache. They can also improve when a customer calls and asks to speak with a manager that the dispatch picking up the phone doesn’t tell you “it doesn’t sound like a big deal” when you explain why you want to speak with the manager. It’s not their business to decide what’s a big deal or not and further they can improve by the manager actually calling back to see what happened. Overall what should’ve been a simple and nice experience turned into a terrible headache.

The actual company didn't even come out. It was another company. Seems like a referral service. But at least their prices were 20% higher than any other bids I got.

When I was choosing an HVAC provider to repair my AC unit, I received a very convincing “pitch” from a representative named Joseph who told me about the company’s 1 year warranty and their excellent reputation for service. I was impressed and went with them. Someone else at the company - not Joseph, who I guess is someone who sells not repairs - did the work promptly and for the agreed upon price—so far, so good. Unfortunately, after the repair was completed, there were issues. The unit is much noisier than what it replaced and it is interfering with my sleep every night. I’ve contacted the company multiple times and have heard nothing back regarding my issue. I feel that this company convincingly promised great service and has since ignored a customer who spent over $6,000 and has a legitimate problem. I cannot recommend them given this experience.

I had a great experience with United Heating And Air. They responded fast and were really helpful and professional. They fixed my AC unit the next day after booking them and I can not be more thankful. Some other companies told me it was not fixable but United team was honest and was looking after my best interest without overcharging me for something I did not need. HIGHLY recommend!!
