I installed a new HVAC system in the house that I just purchased. The install was fast especially due to COVID. I did not like the way they covered the pipes for the ductless unit initially, s I called them to come in an d re-do. They fixed some of the issues but not all. I called again and they fixed everything nicely on the third try. Point is, they came in and re-did what I asked. No excuses or trying to skirt the responsibility. They also helped we with tewiring the existing zones.

Would give 0 stars if I could. BUYER BEWARE! Don't waste your time and hard earned money. Installed new Central Air Unit. They have to keep coming back every week to fix things and never fixes the problem, which ends up costing me more money because I have to hire someone else to fix it. Bad attitude from the owner. Never takes responsibility for his work and blames the customer for THEIR own errors. I would NEVER recommend this company to ANYONE.

Called to set up routine appointment. Didn't call back for more than 24 hours. Finally got a call back. Phone manner was rude. Asked for part replacement, and was rudely told to take a picture, or else, no part would be ordered. Described the part, and provided part number in great detail. Service manager wouldn't get on the phone to discuss. Customer Service, a solid F+. Don't even want service based on the conversation.

They are the WORST. Their AC units don't work and they blame us for the problems. Our units have been broken for 5 years and they never fixed them correctly. When they finally did something about it they said our Midea units were no longer in business and we had to have Mitsubishi ones installed. They wanted us to PAY for the new install. The owner was rude, used cuss words and asked if we were going to take him to court. He's not worth my time so we are going with a new and reputable company. I hope custom air goes out of business.
