Tony was very professional and friendly. He explained everything thoroughly and spelled out our options so we could make the best decision for our circumstances. He went above and beyond by assisting us with an unrelated issue. We would definitely call Everest again.

Had them install a mini-split at my house. Installers were very careful to minimize damage to the house (yes there’s always damage when a new appliance).

Furnace Repair

I want to thank Everest Mechanical for adding a filter system to our furnace, honoring the warranty from another company even though they didn’t have to. Everest did the work for free!
Thank you again for your integrity.
