"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 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."

"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

You may never need an AC recharge if there are no leaks. However, if your AC unit has a leak that cannot be patched appropriately, you’ll need an AC recharge every time the freon level drops low enough that it disrupts your system—this could be once every two to three years. It all depends on the size and frequency of the leak.

You should flush your AC drain line once every three months to keep it clear of debris and buildup. Keeping your AC drain line clean prevents clogs, backups, mold growth, and extra wear on your AC unit. If you live in a humid area or have several furry pets, up your cleaning schedule to once a month.

This is a bit of a trick question. Even though the seasons arrive at the same time every year, the weather doesn’t always behave according to the calendar. So, while it’s fair to say that you can expect to turn on your AC starting in late May or early June, it all depends on the outside temperature and how cool you like to keep your home.

AC capacitors have a wide lifespan, ranging from five to 20 years, with an average of about 10 years. Many capacitors will last for the entire life of the air conditioning unit, and most homeowners only need to replace one once. A capacitor should only be replaced if an HVAC professional diagnoses a problem with it. Premature failure can be caused by overheating, power surges, or short circuits. You can help extend the life of your AC capacitor by scheduling regular AC maintenance each year.

As mentioned above, not all HVAC Schrader valves are necessarily the same. While the valve core and pin or spring size on Schrader valves used for HVAC are generally similar, the valves are not all universal and interchangeable. The size of Schrader valves varies depending on whether it's used in an air conditioner, bicycle tire, or motor vehicle tire.
