SureFire Mechanical is a professional and top-notch company. I've had trouble finding someone to handle my furnace maintenance: had a few instances of people just not being professionals, leaving me hanging when we had a scheduled appointment, not really doing a thorough job, or leaving me with a furnace that was "sort of" functional. SureFire Mechanical's personnel, on the other hand, are extremely professional. They are easy to make an appointment with (they respond to email or phone), do a thorough job, are willing to explain exactly what they are doing and why, and the owner - Jason - solved problems that in fairness, were not really his issues, but he felt compelled to take them on in order to do a thorough job and leave things in a state that he was comfortable.

With an old furnace - mine is 20 years old - there are so many things that can be serious hazards. Just because these units exist in every house doesn't mean that they are adjusted correctly, serve the owner efficiently, and that they don't introduce risk. I had every sense that Jason takes his company's work very seriously, maintains his own standard for safety and quality, and will stick with a job until it's finished to his satisfaction, including dealing with all the little unpleasant surprises that can come up in dealing with old equipment. ...Oh, and btw, he does this in a good-natured manner, with the wisdom of someone who has been handling these types of jobs for a while, doesn't surprise easily, and doesn't nickel and dime you in doing the work. Anybody would do well to hire these guys.

After buying a house with a complex radiant heating system consisting of 14 zones, I lost heat in two of the zones shortly after moving in. Because of the complexity of the heating system, l wanted to find an HVAC expert that was familiar with such systems. I reached out to Surefire Mechanical (based largely on the many positive reviews that they have on Home Advisor), and Jason and his team showed up promptly. They diagnosed and fixed the problem (two of the circulation pumps had burned out). Further, they noticed that my heating lines were full of rust and other sediment due to the fact that I am on well water and the lines are constantly topped-off with water that is high in sediment, minerals and metals. This was preventing the circulatory pumps from running efficiently and causing them to burn out prematurely. As such, we decided to install a whole house water filter (that I purchased from Amazon), which Jason installed seamlessly. Jason also flushed all of the water in the 14 zones (many of which were becoming clogged) so that the lines contained only filtered water (without the high sediment, minerals and metals content). We have not had any circulation pump issues since, and our water quality has been immensely improved.

In addition to the work above, I have used Surefire Mechanical for several other HVAC needs, including servicing my oil burner and hot water heater, rerouting my plumbing in order to relocate a washer and dryer, fixing a leak in my shower plumbing, and servicing my central air conditioning units.

I highly recommend Jason and Surefire Mechanical for your HVAC needs. After 2+ years of using them, they always show up promptly and fix any problems efficiently.

Overall experience was favorable and pleasant. They were able to quickly assess what was wrong and repair the problem. I highly recommend them!! I used Surefire again on Dec 12, 2017 to resolve an issue with my new Nest Thermostats. They were able to come in and install a Common Power Sharing Wire and resolve my problem. This is the second time I have used them in less than two months. I would highly recommend them!! Courteous and Professional!!!

Called this afternoon, got called back within 10 minutes, appointment this evening. Jason literally pulled up to my house seconds after I got home from work. Total elapsed time from arrival to my heat being on was less than 30 minutes. There was a clogged line in the heater, which Jason just cleared out and got it working. No trying to get me to purchase stuff I don't need, no upcharge for same day. Polite, cleaned up after himself, nice to my dog. Awesome. Highly recommended.
