Best heating and air conditioning pros near Thornton, PA

"Great company run by friendly people. Joe and his team know their stuff. Deborah is a pleasure to speak to on the phone. I first called due to some weird behavior with my HVAC and wanted them to come take a look. Before they arrived, the HVAC started working ok again. I called them back and when I told them what was going on, they explained that there was nothing wrong and the weird behavior I explained was actually normal based on what I had my thermostat set to. No visit and no fee required. A lot of other service companies might have urged a visit and charged me the fee. I then hired them for a regular maintenance service contract, and they have been fantastic. Always show up on time.

"I would give MORE stars if I could. Service was excellent. Greg arrived at the appointment time, was clear about what he would do and how he would do it. He was very clean in his work. He removed all duct covers, then began the cleaning. I had some issues with the antibacterial disinfectant (allergies) he would be using. He advised I could research it and let him know. He even allowed me to smell the disinfectant. We did use it and the smell was very mild and dissipated in about a half hour. After cleaning the duct work, he returned all the duct cover and cleaned up his work area. He worked by himself and had the job done in under 3 hours. And the price was fantastic, coming in at over $150.00 and $300.00 less than 2 other bids. If you're looking for duct cleaning for your HVAC system or dryer (he did that, too!), The Duct Pros are where you want to go! Thank you Duct Pros!"

"There was a snag at the beginning when they realized, after beginning to dig, that the AC unit was on top of the oil tank and they'd have to call someone in to move it before digging could continue. That delayed things a few days, but thereafter they did a good job of digging and were very careful with our trees. They also took care not to ruin the lawn with the machinery. The new tank and heater were quickly put in the basement with no problems."

"The install was a smooth process. They were professional and provided guidance on appropriate unit selection for the space. I would certainly rehire WM Henderson Plumbing & Heating for future HVAC projects."

"The technician Adam couldn't have been more professional and helpful. He arrived on time and was very courteous. He quickly was able to assess the problem and repair it. I'd recommend One Hour Heating and Air Conditioning to anyone looking to install or repair their HVAC system."

"My initial contact with Mattioni was to simply schedule a winter check-up on the furnace in our new house. I knew the furnace, a/c, and water heater were all about 11 years old and could be in need of replacement. One month later, I’ve had Mattioni replace all three and also perform some smaller plumbing jobs after the annual healthy home plumbing inspection they offer as part of their contract program (which came free for one year after I had the furnace and a/c installed). They’ve done too much work for me to go into detail on every aspect of every job they did, but, on the whole I have been very impressed with Mattioni. Their customer service, quality, and attention to detail seems top notch. If you’re just comparing prices, they’re probably not the cheapest contractor to use, but if you factor in the quality of the service they’re providing, I think their prices are very good, which is why I rated them A in this regard. As with any big jobs like installing a furnace or water heater, small hiccups can occur - in fact, a week after the furnace was installed and I had the plumbing inspection, a small gas leak was detected. After the hot water heater was installed, one of the fittings in the pipe that leads into the water heater leaked a small amount of water and set off the alarm they installed. In my view, small hiccups like this are to be expected when new installations occur. Where Mattioni really shined was in their response to these problems. In particular, I would recognize Jared C., the plumber who did most of our plumbing work. He noticed the small gas leak and had one of the HVAC techs sent out within several hours to address it. He also returned the late the same day he had installed the hot water heater to correct the small leak that had resulted from a defective fitting. I found his attention to detail and willingness to help my wife troubleshoot over the phone and then return late after a long day and fix the small problem to be exemplary customer service. On the whole, I highly recommend Mattioni. If you’re just interested in finding the contractor with the lowest price, Mattioni is probably not going to be your preferred contractor (although they were willing to match lower quotes I received on the hot water heater install). If you’re looking for an HVAC or plumbing company that has responsive and friendly customer service, technicians that pay attention to detail and treat your house as your own, and will ensure that the job is done both correctly and with a high degree of quality, Mattioni seems to be one of the best I’ve used in my years as a homeowner. They will certainly be my go-to plumber and HVAC company for the foreseeable future."

"We recently had a new system installed by Trustwell Heating and Cooling and could not be happier with the experience. From start to finish, everything was handled with care and professionalism. Tim and his team were on time, respectful of our home, and kept the work area extremely clean throughout the install. The pricing was fair and clearly explained, and the quality of the work really shows. The system is running great and we feel confident it was installed the right way. It is refreshing to work with a company that takes pride in their craftsmanship and truly cares about doing things right. I would highly recommend Trustwell Heating and Cooling for any installation or HVAC work."
