Syed did a fantastic job with our furnace inspection and thermostat. Extremely polite, professional and knew exactly what he was doing. Give the man a raise or bonus, he deserves it. He is an asset to your company.

I had an emergency last week. During the coldest week so far this year my heat went out. I called several contractors and no one could come out until monday and this was Friday. I was resigned to have to bundle up and use space heaters until Monday. Syed called unexpectedly late friday afternoon and said he was nearby and could come by right away. I was so relieved. He diagnosed the problem quickly had what was needed on his truck and fixed it in less than thirty minutes. HEAT!! He was proficient, polite, professional, and very knowledgeable. He is my new "go to guy" for HVAC issues. Oh, and very fair price. I would definitley recommend.

We had an issue with our HVAC yesterday and Syed came today and checked everything thoroughly. He not only resolved the issue but also provided helpful inputs to take care of HVAC for future. He patiently answered all our queries and was super helpful. I will definitely be using his services in future.
