"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!"

Heating and Air Conditioning questions, answered by experts

One of the first signs of mold in an air conditioner is a musty smell. You're likely to notice the smell when the unit runs, from the air coming out of the vents or the unit itself. You may also be able to see mold growing on the unit, such as near the condenser coils or by the fan. In some cases, there may be visible mold by the vents.

You can protect your air conditioner in the winter by turning off the power at the thermostat and performing routine HVAC maintenance in the spring. Regular maintenance, cleaning, and repair of your AC unit helps protect it and extend its life span. If you have a window AC unit, remove it from the window and store it in a dry place during the winter. Window units cannot withstand freezing temperatures. Keeping them in your window also allows cold air to seep into your home.

It depends on how fast an HVAC technician can resolve the issue. First, if there's a refrigerant leak, you’ll want to keep small children and pets out of the house. Next, you’ll want to turn off the AC unit to ensure no more freon enters your home. Finally, you’ll need an AC technician pro to come to your home and fix the leak immediately. Ultimately, it’s best to leave your home if you discover a freon leak—the risk of exposure is very high, and it’s not worth risking your health to stay.

While it is possible to add Freon to your AC unit yourself, it is not recommended. In fact, the U.S. Environmental Protection Agency (EPA) prohibits the handling of Freon without a license. Freon is a dangerous gas that can cause irreversible damage to your AC or yourself if not installed correctly. It is worthwhile to hire a professional to add Freon to your AC.

Common signs of insufficient return air include uneven temperatures, with some parts of your home feeling hotter or colder than others, and noticeable differences in air pressure between rooms. You might also observe that more air is blowing in rooms closer to the AC unit. Leaky air ducts can also be a related issue or clue.
