"Mat and his team are consistently awesome. The first couple years we owned our home we struggled to find a reliable HVAC company to help us. Once we found Home Mechanix we were so relieved, and have never looked back. They’re always prompt, respectful of our home and business (they’ve done work at both), friendly, and happy to explain all work and maintenance. We won’t use anyone else for our HVAC work, period."

"My air conditioner stopped producing cold air Saturday evening, but I noticed so late that I had to wait until Sunday to try to get it fixed. I called the company I typically use for my HVAC and was told it would be $230 for them to even come to my house because it was a weekend. I completely understand a weekend being overtime, but I didn?t want to pay the additional fee so I told them I could wait until Monday to have it fixed. A technician was supposed to call me back to schedule a time for them to come on Monday, but they did not end up returning my call on Sunday. While I waited for the other company to call me back, I looked at Angie?s List to see if there were any highly-ranked companies I could use instead. John Mullen Home Repair was one of the companies I had planned to call Monday, but I noticed the hours said they were still open so I called at 6:00 PM on Sunday, fully expecting to schedule them to come Monday. John answered and said that he was on another job that he expected that to wrap up shortly and that he had another stop to make after that, but he thought he could get to my house around 7:00 PM. At this point it was about 85 degrees in my house with all the windows open, so I agreed to have him come out even if it meant an additional weekend charge. Around 6:45 PM I received a call from an employee of John?s saying he would be at my house in about 15 minutes. In talking to John, it seemed like he was going to be the one who came to my house, but I?m assuming he ended up sending someone else because he would have gotten to my house later than his estimated 7:00 PM. Having had to wait many hours for various service people to show up for their appointments, I was very impressed and pleased that they cared so much about meeting the appointment time. He showed up right around 7:00 PM and almost immediately diagnosed the issue as a blown capacitor. My air conditioner is fairly old and has actually blown a capacitor before, but the previous time it broke I used my typical HVAC company who charged me $250 for the capacitor on top of the labor and additional weekend charge (because of course it broke at the beginning of a 4-day holiday weekend where every day was in the 90s). The guy from John Mullen charged us $100 total for the capacitor and the labor. I was very pleased with that as well, so I mentioned that I?m probably going to replace my AC unit sometime in the next year and would be interested in using John Mullen. He said he noticed that the unit was older and that we could probably just run it until it dies, but explained a few of the newer units they have and the pricing for those. He wasn?t pushy at all and didn?t try to sell me on anything immediately, which I appreciated. To summarize, it took John Mullen Home Repair about 1.5 hours from the time I called them to the time they left my house after fixing my air conditioner, all for $100. I am very happy and would definitely recommend using them."

"They installed our HVAC system two years ago and they service it every 6 months. We have the furnace checked in the winter and the air conditioner checked in the spring. They are very reliable and professional and they do a great job."

"We hired Bactronix to clean the HVAC ducts in our house. Technicians Masson and Shawn arrived on time, did their work unobstrusively and efficiently, and answered all my questions politely and fully. They sent over before and after pictures of the ductwork by e-mail afterwards. Their work has made a positive difference to the air quality in the house, and we appreciate their services."

"The phone rep (Angel) was terrific and professional. The cleaning visit left some things to be desired though. The workers left a mess behind--dirty fingerprints, dirt, and grime underneath and alongside the vents they cleaned, muddy/dirty water on the front porch, etc. They gave a hard sell to convince me to upgrade the cleaning services--bacterial treatment, allergen treatment, etc. They did not wear booties in the house or remove their shoes either--just tracked in dirt from outside all over our floors and carpets. The team did NOT have cameras to inspect the ductwork before and after the job or demonstrate its effectiveness. They used a WATER SPRAY to clean, which I had never heard of before--was expecting brushes and negative pressure/vacuums. I am not crazy about the idea of spraying water inside of my walls, ductwork, etc. and the EPA does not recommend it. The workers said that the ducts will take a few days to dry out. They charged me extra to clean out a couple of HVAC trunks in the house because they were not accessible directly from the vents--then when I asked how they accessed the trunks, they told me that they were able to reach them from the vents after all. Since they do not use cameras, I have no idea if they were actually cleaned, or how they were able to ascertain one way or the other if they reached them, or if they were successful in cleaning them. The price quoted over the phone was very reasonable. When they visited in person though, the up-charges put them right in line with competitors--double cold air returns, HVAC trunks, etc. In hindsight, I would have rather used a more professional and cleaner crew and spent another hundred bucks."
