"They were very responsive and reached out immediately to schedule an appointment that worked for my schedule. Arrived on time and cleaned, serviced, changed filters and showed me how to maintain our system during the year. I will call them again when we need HVAC service or repair."

"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."

"Would absolutely recommend John Mullen and his company. From the first time I called John he was very responsive and professional. I had called multiple other HVAC companies to install a vent through a brick chimney and were having trouble finding someone who would even come take a look to see if they could tackle the project. John didn't hesitate and came out and talked to us to find the right solution. Once we were ready for the job we were able to schedule him within about two weeks and he called the day of to see if they could come a bit earlier than planned. I truly appreciate the quick and professional communication throughout the whole process. The guys that came with him to do the work were also professional and they got the job done quickly. The price we paid was very reasonable for the length of time they spent and the difficult job of drilling out through brick."

"A great company, from the estimate to the install they were on time, informative and very professional. I really think I could not have found a better group of professionals to replace my current heat pump and air handler. Kudos to this company, I highly recommend you give them a shot at your HVAC needs. If their service is as punctual and professional as they have been for the install, I'm not sure you could find a better fit. Thank you Air Systems Mechanical and please say thank you to your team of guys for me who installed my system, they were outstanding! I found my go too for all my HVAC needs."

"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."

"It was trying, but they made sure that the job was finished.
First time, the tech did not have the video equipment to see where the clog was. He said that the sewer pipe was clean.
Second visit, he found a tree root under my driveway, right near the outside drain. He put in a patch job, in the inside sewer line. Everything seemed to be OK. Then the sewer gas came back.
I called and they sent out Paul. Very professional and experienced tech. He found a leak, and traced it to the source, and fixed it. He redid the patch, and was extremely professional!
I would call Sullivan back and ask for Paul. I asked him about the other services, and he told me about the HVAC, and he said that they could install furnaces, annual checks on HVAC.
I appreciate all that was done to make the job done right. I feel that 3 visits is not their norm I just feel that the had a technician here that needed to be shadowing an experienced tech.
Thank you Sullivan.

"Highly recommend Kenders HVAC! Both our furnace and air conditioner broke down at the same time, which was a huge stress, but the team at Kenders handled everything flawlessly. They showed up right on time, gave us a very reasonably priced quote, and managed the entire process from beginning to end in less than a week. Their team was professional, efficient, and left everything spotless. If you want honest, high-quality, and fast service, look no further than Kenders!""

"Excellent service. Professional and quick! 100% would recommend. I live in a 100-year-old home whose ducts had never been cleaned. They managed to get it done quickly and the air feels so much better now. They even cleaned a birds nest from my bathroom extractor! Will be hiring them if I ever need carpet or duct cleaning done in the future."
