Javier was amazing! He was very professional, personal and passionate about what he was doing. He not only fixed our problem the same day, but he made our furnace run at a more efficient and effective way and the way it was designed to. He switched the heat to come out into two stages instead of just the one that it had been set at for years. Javier even took the time to explain everything he was doing during the process. Thank you so much Javier and well done!

Sean did an excellent job of replacing our thermostat. He was friendly, professional, and thorough. He made sure everything was running right and he answered all my questions. He was very easy to talk to. Said to just give him a call if we need anything else.

These guys are rockstars! My furnace went down and they had a new one AND a new air conditioner installed and running, in less than 24 hours. Would highly recommend! The whole team was awesome! Thanks to Kevin, Travis, Brandee and Evan.

Alexis came today to change filters on our 2 units. She did maintenance for our last visit when we were having problems with heat. She did not waste time then nor did she today. But what I really appreciate is that she said she would return to change the filters. I used to change the filters, but it’s become too burdensome. Alexis did today exactly what she told me she would do. She also ordered the filters I will need replaced this spring. Brilliant! No one has ordered these ahead before. She is polite, respectful and made sure she was quiet since my grandson was napping. She’s like a ninja…quiet and stealthy while accomplishing tasks with great precision .

Disappointing! I agree with another review left 27 days ago "This company is made up of salesmen first and technicians last."
Firstly, I will say I am in sales so I do understand the principal to lock in clients with valued offers, no harm in that. However, the tech came over, within an hour on a very cold day when my furnace was out (5 star) and took a look at the unit.
He then tells me that I simply need maintenance and he can sign me up on a program where they come out and service I believe twice a year. Detail to the program is irrelevant as I told him I was going to be selling my home and would like to simply understand what needed repaired for today. I then got a strait face and he seemed to not know what to do next.
I had to ask multiple times what needed repaired and the only response I could get was maintenance. I asked what part and was not given a answer. He then said, I tell you what - you will be charged $99 for the service call, albeit there is an offer for new clients to have this waived, of course that was not mentioned and then an additional fee of $240 to repair the furnace. He then said and I quote "I will do a bit more work while down there to make sure you get your moneys worth". What does this even mean??? I have NO IDEA on what was actually repaired. The root cause was a dirty pilot light that simply needed cleaned off.
The invoice states "Minor incidental repair required to restore unit to full operational status." Charge $238 - in total $337. (1 star)
I don't mind paying for service but to not be clear with clients on what they are paying for is absurd. The only reco this person was pursuing as a solve was to enroll in the maintenance program. Had he started off with what the actual issue was, cost to repair that, and then offer up a maintenance option that would have been ideal - train your team how to interact with customers and selling 101.
