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.

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.
