THE ABSOLUTE WORST!
Home Depot jobs out their AC installations to Danisi Energy, which is the ABSOLUTE WORST! They installed mini splits at our house April 2019. They didn't finish covering the ugly black cables on my house exterior, claiming the contract only covered the vertical cables!!! Not the horizontal ones!!! If they ran them under the soffit or down along ground level might have been less noticeable, but they ran smack in the middle of the wall!!! It took calling Home Depot for NINE MONTHS (!) to finally get the ugly black cables covered!
One month later one of the units flooded

Danisi is the best !!!, They came out last night in the cold and cleaned my boiler ( I just had one of those face book fly by nights do it 2 weeks ago) . After my house filled up with smoke I called Danisi after my neighbor said I should call her company, they always respond and she was right!!. Mike came with 20 minutes and said the parts the other company used were wrong , The nozzle was way to big, anyway after about and hour he had it running and safe. I would recommend DanisI to anyone who wants good honest fast service !!

In October I was having issues with my boiler, so of course I called on Danisi. 10 years ago my boiler broke down and I called on Danisi. They were quick to respond to my call. It turned out that I needed a new boiler. They were able to install a new boiler the next day. So last month when I was having issues with my boiler, I called on Danisi. Jay, Mike and Chris were very knowledgeable and helped my family and I out in our time of need. I could never praise them enough for taking the time to explain everything they were doing and not take advantage of us. A major thumbs up for Jay, Mike and Chris

Jason A from Danisi Energy came to us on Saturday for an inspection. He was fantastic. Thorough. Professional. Polite. Friendly. He took his time to look at everything and explained things to us in a way we could really understand!! It was an excellent experience and instills confidence that we have engaged the right company for this service need.

Thank god for Danisi Energy. My heat went out when it was 6 degrees outside. I called the company I have a contract with and they told me couldn't get to me until the next day. I called Danisi, they were there in less than 4 hours and fixed the problem. Needless to say, I am canceling my contract with that Big Oil company I was dealing with and moving it over to Danisi! Thanks Danisi fuel for getting me out of a jam.

NEVER USE THIS COMPANY!!!
For 4 months I have been trying to get my home fixed from the water damage by Danisi Energy. I tried to do the right thing by going through Home Depot services and they chose Danisi Energy to replace my central air conditioner. They company had 3 different crews, for a total of 4 times to do a simple replacement.
Crew one came for initial install, multiple issues
1. Did not pitch the air handler so water began to over flow and you can hear water tapping on my ceiling the next day.
2. Claimed he never heard or saw of a Nest thermostat but during the estimate, I was

If only I could award them no stars I definitely would.
They installed my new central AC & were horrendous from the start. They initially installed ductwork in the center of my living room, cut up my floors, didn't install the filters & had to return to do so after I called to complain that the house wasn't cooling very well. One of the workers stepped through my ceiling & they weren't going to repair the damage!! They even tormented my dogs; who were crated during the installation. I could go on, but I just don't have that much time, sorry.
