Harrison W.

I recently had Mainstream inspect my furnace and A/C and their service was nothing short of exceptional. Zach was not only punctual but also incredibly thorough in their inspection process. He took his time to ensure everything was checked and double-checked, leaving no stone unturned. 

Netha M.

Ryan was personable, professional, and extremely knowledgeable of our intricate A/C system. We make it a point to use Mainstream for all of our heating, cooling, and electrical needs. Top notch company that truly stands behind its work.

Shannon B.

They are courteous, responsive and very knowledgeable. The Technician repaired our furnace quickly! We are so grateful and will be using their service in the future!

Brandon E.

Joe was phenomenal. He not only did a thorough inspection of our furnace, he took the time to explain what he was seeing so that I could feel more confident in the overall status of my HVAC system. I will absolutely be sticking with Mainstream .

Laurie R.

Parts for the furnace were way back ordered but Kenny was able to do something to keep our furnace running during all this time. I would recommend Mainstream above and beyond ANY other heating and air conditioning service!

Sheree G.

Mainstream is prompt, professional and courteous. I had my entire HVAC system installed by Mainstream and it’s outstanding.
