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.
