"Before using this company, I did my research. They were the best priced, fastest to get an install and responded quickly. I would highly recommend them if you need a heat pump in the Bangor or Ellsworth area! The Install was so simple and didn't take long at all. Nate made sure I understood how to use it and double checked his work on site. I have been building a house and they were by far the easiest contractors to work with. Their price was almost half of what I was quoted elsewhere.. so I will be having 2 more installed coming up! I also love that they will come back whenever needed and will do all the cleanings themselves. I highly recommend them!"

"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."

"It was late at night when we realized our water heater blew and flooded our basement like a swimming pool. We had to find a plumber and fast. we came across SWB he was out here within 30 minutes from our call the job he did was impeccable. He went above and beyond he went and got us a new water heater, installed it, and then stuck around to help us clean up, Since then we’ve used him for several other projects. Every time the professionalism came with him I would highly recommend him 100%."

"Josh did a great job on the roof repair. He did the job when he said he would. He picked up the materials so I didn’t have to. I would hire Josh again and I would recommend him as well."

Heating and Air Conditioning questions, answered by experts

For the most part, you should leave your AC fan in “auto” mode so that it only runs during a heating or cooling cycle. Keeping it in this position uses less energy, which equals lower utility bills. However, there are some situations where it’s better to leave your AC fan on, including if you have allergies or there are lots of people in your home.

Winterizing can still help you save money on energy costs and help prepare your AC for its work next year when you turn it back on. We suggest planning for at least some maintenance, even if winters are mild in your area.

If your home has an existing forced-air heat system, you can add a central air conditioner to it. An HVAC technician can retrofit your forced-air heating system by installing an evaporator coil onto the furnace plenum, the box next to the furnace that draws in air. Once installed, the air conditioning coils use the furnace’s blower to circulate the air.

When deciding whether to repair or replace your air conditioner, several factors should be considered. It is generally worth repairing the unit if it's less than 10 years old, the warranty is still active, and you're dealing with a one-off issue. Most central AC units last about 15 years, while window units last 8 to 10 years. If your unit is approaching or has surpassed the 10-year mark and requires frequent or costly repairs (e.g., over $5,000), replacement is often the more sensible long-term investment. For older, inefficient, or out-of-warranty units experiencing multiple problems, replacing it is typically the better choice.

As a general rule, you should have your HVAC system professionally serviced at least once a year, though it's best to follow the manufacturer's specific recommendations. Many experts suggest twice-yearly maintenance: once in the spring for the cooling system and once in the fall for the heating system. This is especially recommended for older units, systems with recurring issues, or heat pumps that provide both heating and cooling. Regular service, which can cost between $100 and $550, keeps the system running efficiently, helps prevent costly future repairs, and saves money on utility bills.
