We have been thrilled with the ongoing service we’ve received from NASA Heating and AC. Amit is always responsive, courteous and extremely professional. He always provides cost effective options, and takes phone calls day and night. When we’ve had emergencies, he’s been there to solve the problem. When we’ve needed new equipment, he’s sourced and installed on time and on budget. In short, NASA is all about service. They are the best.

Tony in Toronto

Best, most informative and thoughtful contractor it has ever been my pleasure to deal with. He planned and thought ahead, saving me untold grief when events might happen in the future( which did occur in one instance). I would very highly recommend NASA heating, and I personally use them at my home and office, even though I am far away.

John in Belleville

Our air conditioning system finally crashed this summer.i called several contractors but finally settled on Mr. Gupta who was eager to assist, competitive in price, extremely knowledgeable and quick to respond to any questions.as well we had installed a new furnace 3 years earlier but there was a problem with its installation which Mr. Gupta brought to my attention.he called back after the job was completed to be assured i was satisfied this does not happen very often these days.i have been a home owner for 35 years very good service.

Bruce in Richmond Hill

Amit was recommended to us by 3 different neighbours who were pleased with his services. He made a special point of doing our work earlier than planned due to the extremely hot weather we were having at the time. This was very much appreciated. We are very pleased with the results.

In the winter of 2019 my tankless water heater froze and broke. Amit promptly came out to replace it with a new standard water heater. Professional, and clean workmanship. Good price, good warranty.

Aliciya

My hot water tank started to leak over the long weekend and when I called NASA Heating and Air conditioning the following business day, Amit was able to provide me a quote for natural gas hot water tank installation over the phone. On top of providing me the quote, he was able to schedule the hot water tank installation the same day.
