Service person arrived within the designated time window and was through and able to diagnose the problem quickly. The repair part was ordered and I will be contacted for scheduling when the part arrives. Service person was very knowledgeable and helpful. Great service job.

Called regarding a click in my furnace. Garry arrived the next day, evaluated and diagnosed the problem. He took the time to explain what was going on and showed me the photos he took. Got the replacement scheduled quickly and efficiently. Highly recommend this company!

Lee was exceptionally kind and very informative; he took the time to explain the issues he noticed during our routine furnace inspection and help me understand what repairs were necessary and why. Not exactly news any homeowner wants to hear but it helped that Lee was a clear and kind communicator.
