    I had not been using my A/C heat pump because I thought it was too expensive to repair and older unit. He came by to give me an estimate on referral from a friend.He came in and went to the attic, then worked on the thermostat and then worked on the outside unit.He explained what needed to be repaired and how much the costs were. He made the repairs. Before he left he sure the a/c and heating were both working. He answered all my questions.The heat system has been working great for 3 days now.I am very thankful for his help and hard work.

    Bryan is extremely knowledgeable and truly a master of his craft. Our HVAC decided to stop cooling a late autumn day. Brian and his team were able to properly diagnose the issue (refrigerant leak) and replace the faulty piping. He ran the new piping through our attic and after the day was through, our AC was back working at 100%. Thank you McMaster Mechanical for all you do for our community!

    Kevin was out and serviced my heater yesterday and as always he’s so thorough. He repaired a small gas leak and found the electrical outlet was loose so he replaced that as well. It so nice to find competent and honest people to service items in your house anymore. He’s truly a treasure and I’d recommend him to anyone!
