Can’t say enough GREAT things about Comfortech. Our relationship initially began a couple of years ago when they replaced a faulty piece of HVAC equipment in my attic. It was covered under a manufacturer’s warranty. A couple of months later, another unit misbehaved & it was David to the rescue. Both times, David &/or his crew were on time, performed the work with minimal interruption to the household, & quickly completed the work with lasting professional results. David’s labor rates & equipment prices are as reasonable as they come & the quality of work is above & beyond any other experience I’ve had PERIOD. I have since recommended David to my own Mother(got a whole house HVAC makeover) &SEVERAL other family members, friends, & any other chance I get to share. With a sea of HVAC technician/installation/service folks from which to choose, Comfortech should now, & forever more, be the only call you make for any HVAC related need. PS– Be sure to use their annual service plan. It’s well worth it. Preventative maintenance, like your auto, is the best thing for the most expensive piece of equipment in or attached to your home.
