Complete HVAC Solutions for Trenton & Quinte West

Would 100% recommend Brandon, I called him in a panic with a newborn and a heat pump system that wasn't cooling our house in the middle of August, after another company gave us a ridiculous quote. He got it done for half and came the same day I called. Thank you so much.

Realized my furnace went dead and made the call, had a technician in in a few hours and they found the issue had the part ordered and was installed the next day, professional kind and quick 10 out of 10 would use again.

We are new to our home, and weren't sure who to call for an outage with our home heating and cooling system. We found Johnston mechanical through an online search, and are very glad we we contacted them. They were honest, dependable, and fixed up our system in a professional manner. I highly recommend this business to others!

Johnston Mechanical HVAC installed a radiant natural gas heater in my garage. They were professional, punctual, competitively priced and had a clean job site. Additionally, he took the time to answer my questions and explain the process. Would recommend

While searching for a new HVAC repair and service firm, we were pleasantly surprised when we found this company. Their response time was very punctual and the level of service we received was second to none. We had the opportunity to meet the owner Brandon Johnston and found both him and his team to be very friendly and professional. We know that our home heating and air conditioning needs are in good hands with Johnston mechanical.

Look no further if you need help with your HVAC system! Brandon came very highly recommended by our next door neighbor when we had our air conditioning break this past summer and he was quick to reply, very professional, and perfectly pleasant not to mention efficient in getting our AC back up and running better than before. We are so grateful he was able to come by on such short notice and have the furnace fixed and running so quickly.
