I emailed him and he said he will come by once he is back. Emailed him couple of time after with no response. Finally on 2/5 I emailed him asking if he is still interested in the project, he said he can stop by today 2/10. When I emailed yesterday to confirm, he said he is not available for foreseable future and they are an HVAC company and don't do just plumbing installs. Very unprofessional and wasted a lot of my time.

There are three rental properties that fed off that same well. I was scared that our tenants would be hugely inconvenienced with lack of water for days. This was NOT the case at all.

He even went above and beyond by providing accurate documentation to help with the insurance claim. Thank you Cota & Cota!

Had to wait months for them to come out and when they finally did, the guy they sent couldn't even identify the heating ducts correctly! Ridiculous. They installed one damper and changed a belt on the furnace fan and called it a day. They charged me a lot for this and didn't even address my original problem. I tried and tried to get them to come back and they just gave me the run around. Said they would come back several times but never showed up. This has been going on for a year and I'm totally disgusted by their incompetence and complete disregard for my time and money. They didn't even have the decency to let me know that this simple job was too much for them to handle. They're absolutely terrible. Worst experience with a contractor in an area where I've found that people have integrity and take pride in their work. Not these guys. Avoid at all cost

James, the owner, told us he had registered our system for warranty, and also told us twice that he had filed a warranty claim for the head (Gree only takes claims through installers). He hadn't. The local distributor kindly promised to do that for us, in January. James took weeks to answer emails, *until we used the word 'lawyer.'* My husband said that besides lying, James didn't seem to know what he was doing, so we got a second opinion hoping to get the heat pump functioning before summer 2024, more than a year later. Another contractor examined the work, and found many issues like connections, wires, voltage, refrigerant. We will be paying this new company whatever it takes to get the system functional. UPDATE: We were delighted that it only took refrigeration and electrician visits, and $1,000 to get our heat pump working! The diagnosis was wrong wires, connections - basically everything done incorrectly. I can say one of the two heat pumps James installed, even though it is not the size we agreed on and is in an awkward place, was working. In the fall we reached behind that compressor to clean leaves, and the wiring fell off! James couldn't even screw on a wire properly! We also found that he had used 110v wires where 220v wiring was needed. tldr, James at Unity was incompetent, took weeks to respond, and wasn't truthful. Strongly caution against using Unity.
