How Functional Is Your HVAC System?

Jeff rerouted an existing propane line to a new whole house generator I recently purchased. The work involved cutting and threading black iron pipe as well as installing a drip loop and flexible gas line on the generator. The work was excellent, very professional and neatly done.
I am very pleased.

Jeff has helped us with our furnace and heating three times now and I can't say enough good things about him. He responds to calls quickly, arrives promptly, and is very professional with his work. We had an emergency furnace leak early on Christmas Eve, and not only did he come to fix it, his pricing was very fair. We recommend him highly.

Jeff Mackay provided us with outstanding workmanship. We were under a time constraint and Jeff went above and beyond the call of duty to get everything done on time. Jeff is the gold standard.

Jeff and crew are honest, reasonable, timely and do meticulous work time after time.Never a worry when they do a job!!!

I had Jeff MacKay Mechanical come install a boiler for me and they produced nothing less than quality work. Jeff was very accommodating and made the installation process simple and quick. Him and his team are very friendly, reliable, and prompt with their service, leaving no mess behind. I would highly recommend!

Yesterday our heat stopped working. I called Jeff and within 1hr he was onsite. Jeff was quickly able to diagnose and fix the problem the same day. Jeff was courteous, professional and his pricing was fair.

Jeff was very professional and efficient. He showed up on the day he promised...which is rare for a contractor...finished the job quickly and kept with the quoted price.
