"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.

"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."

"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!"

"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."

Heating and Air Conditioning FAQs, answered by experts

A new HVAC system can increase your home's value by about 5% to 7%, which can translate to an added value of $2,500 to $3,000. The return on investment (ROI) can be around 30%, especially if you upgrade the entire system, including ductwork and insulation. Adding modern features like a smart thermostat can further increase your home’s value by making the heating and cooling systems more efficient and convenient. However, since a new unit can cost $10,000 or more to install, it's important to weigh the upfront cost against the potential increase in home value. For a specific assessment, it's best to consult a local AC installer.

Your AC might not cool after a power outage because of a tripped circuit breaker, blown fuse, or damage to the compressor or capacitor. If you notice your AC not working after a power outage, in most cases, the breaker has tripped or the system has built-in brownout and blackout protection. Reboot the AC by turning it off at the thermostat, resetting the circuit breaker, and waiting 30 minutes to turn the AC on again. 

You will enjoy greater energy efficiency and save on your annual energy bills, with new, modern HVAC systems using 30% to 50% less energy than older models. Upgrading your HVAC system is also a great way to embrace new technology, such as smart thermostats, lighting, fan speed, and humidity from your phone or tablet.

You should clean your air conditioner at least once per year, but you may need to clean your whole HVAC system (including the air ducts) more often. According to the National Air Duct Cleaners Association, you may need to clean them more frequently depending on factors like whether you smoke, have pets, or have allergies.

In some cases, yes, portable air conditioners are worth buying. They’re a relatively affordable option for cooling small spaces. (On average, they cost between $100 and $500 per unit.) Plus, they’re easy to set up, and you can move them around to cool various parts of your home as needed. However, they aren’t the most efficient AC option, and they tend to be noisy.
