  • I’m very happy with the work they did. If I had to use one word to describe this company, it would be reliable. They keep their word, do what they say they will do, and deliver on their commitments. It’s hard to find that kind of reliability these days. I would definitely recommend them.

    Joseph R.

  • A week ago we got new furnace and AC installed by GPT Mechanical. I waited a week before writing a review to try both heating and cooling. Everything works like a charm. The job was done quickly and neatly. No harm to the utility room and flowerbeds around the AC unit. Prices are lower than in other companies. Thank you, GPT Mechanical !

    Mahyar T.

  • I had my A/C unit replaced and the service was great. Ali was just awesome, he responded so quickly and provided me with a variety of quotes based on the different units available. The price was very reasonable. He went above and beyond by replacing the unit earlier than scheduled because of the heat wave that was hit us. The technician was quick, efficient and courteous. GPT Mechanical was recommended to me by a friend and I am more than happy to recommend them here and to anyone who asks.
