"Incredibly professional, always happy to answer questions. Unlike other places that install and you never hear from again, Cam, David, and crew make sure your heat pump stays in tip top shape with yearly cleanings. They even offered to clean a unit that another contractor put in a year prior who refused to come clean it. I got quotes from over 8 different companies for my second heat pump, and Heat Pumps of Maine were a clear step above the rest."

"I could not ask for a better electrician than Noah Parker. He has come through for me big-time on more than one occasion. Noah installed my generator & showed me how to use it; diligently diagnosed & fixed complex electrical problems in my older mobile home; & even fixed my lawnmower! Not only is Noah an expert at his craft. He is utterly kind, patient, trustworthy, fair, & decent. As a clueless first-time homeowner, I am SO grateful for Noah. I highly recommend him."

Heating and Air Conditioning FAQs, answered by experts

While an air conditioner can temporarily run with a dirty filter, it is not recommended as it will not work efficiently. A dirty filter forces the system to work harder to circulate cool air, leading to reduced airflow, increased wear and tear, and higher energy bills. This added strain can cause the air conditioner to overheat or fail prematurely. Furthermore, a clogged filter may allow dust and dirt to accumulate in your ductwork, negatively impacting air quality. It is more cost-effective to clean or replace filters regularly than to pay higher utility bills and risk needing to replace the entire AC unit.

Ideally, an AC system should never need more Freon (a popular refrigerant) because it circulates in a closed loop. However, refrigerant leaks are not uncommon and may occur gradually over 5 to 15 years. If your system has a leak, it will need to be topped up in a process known as an AC recharge. Signs of a refrigerant leak include weakened AC performance, increased humidity in your home, higher utility bills, and a hissing sound from the unit. The cost of an AC recharge will depend on the size and type of your AC unit, as well as the type of refrigerant it uses.

While many states do not have specific licensing requirements for HVAC companies, your local city or county might. It's always a good idea to check local requirements online and use a tool like Angi’s contractor license lookup to confirm that the company you’re considering is licensed. Regardless of licensing, you should always ensure the company you hire is fully insured to avoid potential lawsuits if a technician is injured on your property. Additionally, it is recommended to check if the company holds third-party certifications, such as North American Technician Excellence (NATE) certification or R-410A certification, which qualifies them to work with HVAC refrigerants.

If you know how to identify supply and return ducts, you’ll find that only the supply ducts will have dampers. Although your return ducts can have dampers, it’s not common. If you have one return duct that is pulling in too much air, adding a damper to it can help with overall system performance. However, dampers on return ducts are not a necessary addition for most homes.

A damper motor can last up to 15 years, but it can wear out more quickly than that if you run your HVAC unit a lot. So you might expect a longer life in a colder climate than if you live in a warmer climate.
