Customer Reviews
Richard Crane
Richard from Klondike was my tech guy that came and repaired my HVAC unit in
my home. Richard went right to work once I walked him into the house and showed him the HVAC unit. He put down protective cover on the floor area and inspected the unit. He was very knowledgeable about my equipment. Found the faulty component right away. After giving me a price to fix the unit he obtained the new part from his truck and made the repair, ran test operation. Problem solved unit back up and operational once again. I then had him perform inspections of the remaining components and perform needed maintenance. He was very careful to explain everything during the process. From phone call to completion of the entire repair, parts replacement and complete inspection the process took just under two hours, fast and very efficient. Can’t ask for more that. Thank you Klondike and thank you Richard.

The Klondike team is great to work with. They installed a new furnace in my attic and a new AC system. They worked hard, fast and were very respectful in my home. I would certainly recommend Klondike.
