 Trustindex verifies that the original source of the review is Google. Coldstream Mechanical supplied and installed our gas furnace and heat pump 2 years ago. We are very happy with that decision.  We recently had them back for an inspection and service on the furnace as well as 2 gas fireplaces.  Also a good experience. We recommend Coldstream Mechanical for install projects and we will continue to have them return for service in the future

 Trustindex verifies that the original source of the review is Google. We recently had our hot water tank replaced by Coldstream Mechanical and were very pleased with the entire experience. Stephanie the office manager, was easy to work with, friendly, and made the scheduling process simple. She was able to get us booked in promptly, which we really appreciated.

The installation was completed professionally and efficiently, and everything was explained clearly along the way. The team arrived on time, did quality work, and left the area clean when they were finished.

Overall, we had a great experience with Coldstream Mechanical and would not hesitate to recommend them to anyone needing plumbing or heating services
