Thank you so much, Mountain Top Heating, for your prompt attention to my needed furnace repair, in the midst of the cold streak that we are experiencing. Your diagnosis was precise, and your work was excellently done. I plan to be a long-term customer!
I give my service 10 stars! The owner was able to squeeze me in today to replace the Inducer blower motor inside my furnace so I have heat again. Very knowledgeable and quick with the installation. I appreciate the honesty and answering any questions I had in depth. Definitely gained a forever customer!
Fast , friendly service at the best price. Installed a central air unit in just a few hours. Left the place clean. Even read my mind on placement of the unit. Would highly recommend for your HVAC needs
I have been working with mountain top since I moved in my house in 2017. This guy is amazing and he does not disappoint. Never had an issue that he could not fix. I would recommend 10 stars if they had it on this app definitely 100% recommend them.
