They were fantastic. We got exactly what we asked for. It was done in 2 days. I'd say their price was pretty good, too. Yes, I would recommend them again, again and again.

I thought the bill was too high. The bill was not itemized in regard to material and labor cost.

Gas Boiler or Radiator Heating System Installation
Very much on top of every aspect of the deal. Initial contact, came out for estimate in an hour, and came the next morning to install for an excellent price. Very professional and courteous installers. In a situation that is very stressful, like not having heat, and they turned it into a painless, care-free experience.

Ducts & Vents - Install or Replace
I had an electronic air filter, UV light, and sheet metal on a return duct replaced. Very professional, knowledgeable, courteous, fast and meticulous. Joe was wonderful analysing our needs, estimating the job, and explaining the process. We were going to consider two other bids but stopped at this one because we trusted Joe. All the work was accurate to the estimate provided and the finished work even exceded our expectations. The guys that came out to do the work were excellent. I'd highly recommend Day & Night Heating. They'll be my service company too from now on.

Central A/C - Install
My project was a difficult one that apparently required a lot of work on the back end. I had a total of three companies come out to give me an estimate - after the first visit, I didn't hear back from two of them. A Day and Night worked diligently through the whole process and installed in two days, cleaning up when they were finished. When there was a small problem a few weeks later, they came out the same day I called and fixed it quickly and for free. I would highly recommend.

Gas Heating and Furnace Service
I had to postpone my furnace installation until fall, but this company is the one I am defnitely going to go with. They were quick to come over, give me a proposal, and work with me ( I am physically disabled). They blew away all other prices for comparable units and work. I can only assume their work will be as professional as everything else so far.

Central A/C - Install
They were professional, courteous, and cleaned up every day. The communication was better than I have experienced in the past with other contractors, and their prices were fair. They have to come back to finish a few things after other construction but I am confident they will. I would recommend them to anyone and everyone.

Gas Heating and Furnace Service
Everyone I worked with at A Day & Night was professional, helpful and responsive. The owner, Eddie, answered any and all questions and concerns I had about the product. Jim, the sales rep, didn't try and sell me anything I didn't need. The install team, Sean and Mariuz did a great job on the install, were on time, and courteous.

Bob and his team-mate's performance was professional. They did an extensive radiator repair in good time; cleaned up after, and to date everything is working well. Bob and his assistant made us feel that they were going to take care of business . . . and they did.
