PAST CLIENT EXPERIENCES SPEAK VOLUMES:

Karl totally saved us when our water heater died. I called him, told him the situation and left for work. When I got home, it was like nothing ever happened except that we had a new water heater and hot water again. He is very professional and fair in his prices. It's so nice to have someone you can trust when things like this happen. Thank you Karl! ​
-Dr. Brian Godines, owner, Eyecon Optometry
Karl installed a heat pump and furnace for us and now we enjoy reliable heat and are able to cool off the house as well. Karl did a great job!
- Gabe O.
Karl Christensen stands out among his peers in the industry. Karl shows up on time, doesn’t do unnecessary “add ons” and really knows his stuff. I don’t just refer him to my clients, I use Karl too and couldn’t be happier.
-Mark Kirshner, Windermere Real Estate
Legacy One has always come through when I have a client who also has HVAC needs. It's nice to know I can partner with Legacy One and have my clients taken good care of with no hard upsells or useless accessories pushed on them. Reliable, honest and hard-working.
-Frederick Brindle, Owner, Edmonds Plumbing LLC
Hats off to Karl Christensen with Legacy One Heating and Air. I had an old ugly fire place that I wanted to do a DIY stone work facade on. However, there was no way I was going to install a new Gas Fireplace DIY. Karl saw my idea and was able to install a great gas insert that matched the exact look I was going for while providing a heat source for the family to enjoy.
