Get matched with top heating and air conditioning pros in 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 serviceman, Hunter, was customer-oriented. He explained each step of the process and wore face mask and booties the entire time. He did not know this, but I also was an HVAC repairman for 45 years, but am unable to do certain tasks, due to age. I would have known if he was BSing me (which he did not), but spoke facts and truth only. A good company to do business with."

"Heating system down - supposedly condo crew cleared outdoor vent accesses. Condo crew failed to perform service. Mattioni performed annual check and needed to get shovel from their truck and go out to vent area to clear the problem area. Mattioni gentlemen could not have been nicer.

"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."
