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.

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 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.

Exceptional service before, during, and after the work was completed. Stays in constant contact throughout the process! 3rd time I've used this group, and will continue to do so! Thanks again!
I was very pleased with the service provided by Amit. He installed my new hot water heater. He was very informative, professional and explained everything to me. His work was neat and thorough. I would highly recommend him and his company
Called Amit as we wanted to turn our AC on and it hasn't been checked for the season yet . He came within a few hours and gave it the ok. He is friendly and efficient . He really takes care of his customers and has pride in his business. I would recommend this company. They are reliable and care.
We trusted Amit with our home and money...he did not disappoint. Furnace, air conditioner, water heater, humidifier all installed efficiently, in a qualitative manner, and at exceptional value. I would not hesitate to conduct business with him again.
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.
Great overall experience. Professional, follows up, and honest throughout the whole process.
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.
Amit and Team from Nasa Heating & Air-Conditioning Services Ltd removed our water tank and install tankless system. They did very good job . Our family is happy with full process. Job well done!!!!!
The job was done well and on time. Amit was courteous, professional and knowledgeable. He even took the time to follow up with us. I would recommend Nasa Heating & Air Conditioning Services.
Amit came the day I called and got the work done in 1 day. He gave a fair quote and did a great job. He really saved us in a bind and was a pleasure to work with.
