Jose resolved a recurring issue with our furnace that stymied another HVAC company for several…read moreheating seasons. Our former service provider tried repeatedly to identify the cause of the error code that would prevent the furnace from starting. They were fully committed to its resolution at no cost to us. Their efforts would be initially successful but then the furnace would stop running again. This season began like previous ones, furnace ran normally for days until it stopped and then would not run reliably. This year, we had contracted our service with Hay's in hope that they might be able to resolve the problem. On the normal maintenance service call, Jose identified a probable cause of the problem and addressed it. For more than a month, the furnace has run reliably (thankfully) and, for the first time, I have a high degree of confidence that the cause was identified and addressed.

I also had Dave look at my upstairs attic furnace and they fixed the shoddy work that my home warranty company performed 1 year earlier.

He looked at it and had to add 2 lbs. to the unit and said it had a slow leak in it, but it did not need replacement just yet, maybe in about 2 or 3 years. Dave was on time and fixed everything that needed to be fix and explained the health of both furnaces and AC units. Good work and trust in a company is hard to come by.

They are super helpful and provide fast solutions (including one time talking us through something over the phone so we were able to resolve an AC problem without a service call). When they replaced our 36 year old HVAC system a few years ago, we signed up for their Comfort Club for the seasonal tune ups and priority appointments. We woke up this morning and discovered that our heat was not working - they were at our house fixing it within a couple of hours. So impressed with the fast service!
