I had a great experience with Superior HVAC ! Ian diagnosed the problem with my furnace immediately, explained every step of the repair, and had it running perfectly in no time. The service was top-notch, and their pricing was very reasonable. I’ll definitely be calling them again. Huge thanks to the team!

Our air conditioner pan cracked and we had water everywhere. I call Superior at 8 am and within a hour Daniel came by when he clearly and professionally explained our options. By 8 pm we had our a/c up and running again. I highly recommend Superior HVAC.
