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.

"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 Trustwell Heating and Cooling install a new system in our home and could not be happier with the experience. Tim provided a fair and competitive price and was clear about what to expect from start to finish. The installation was done professionally, efficiently, and with great attention to detail. The work area was kept clean throughout the process, and our home was treated with care and respect. Everything was explained clearly, and the system was tested thoroughly before completion. It is refreshing to work with a company that delivers both great service and quality workmanship. We would absolutely recommend Trustwell Heating and Cooling to anyone looking for a reliable and honest HVAC installer."
