"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."

Heating and Air Conditioning questions, answered by experts

A dirty AC filter can lower the efficiency of your system, so depending on how dirty it was, you may notice a temperature difference when you clean your filter. You can try other solutions if your AC isn’t blowing as cold as it used to. You can call in a local HVAC tech to make sure everything is running correctly, fix your air seal if it’s a window unit, and clean your coils.

While most air conditioners can last between 10 and 20 years, they will only last this long (or longer) if properly taken care of. Routine maintenance and inspections help keep your AC unit running in tip-top shape but understanding what factors will decrease its lifespan will also help keep your unit running cool.

Some things that shorten your AC’s lifespan include:

  • Extreme outdoor conditions, like high humidity or extensive salt spray 

  • Improper installation

  • Extended run times, either by the unit being too small or the thermostat setting too low

  • Not performing required maintenance

On average, an AC unit lasts between 10 and 20 years. However, the specific lifespan depends on the type of unit, how often it's used, the local climate, and the quality of maintenance. Central AC units typically last 12 to 17 years, while window units have a shorter lifespan of 8 to 10 years. Portable AC units last about 5 to 10 years, and ductless mini-split systems can last up to 20 years. To extend the life of your AC unit, it's important to perform regular maintenance, such as replacing filters, cleaning coils, and scheduling annual professional tune-ups.

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.

No, it's not advisable to only replace the outside AC unit connected to your system. AC units are designed to work as a cohesive system, and older units work differently than newer units. Therefore, replacing only one component can lead to incompatibilities that affect the system’s performance. Replacing one component can void your warranty, costing you money for repairs.
