"The crew sent was on time, professional, friendly, efficient, clean and organized. The electrician was the first to arrive and installed the new breakers to the panel and installed the wire for the condenser unit and the wall mounted blowers. The crew installed two power head blowers, one for a large sunroom and another for the living room. The heat pumps are nearly silent yet powerful enough to do the entire first floor of our 3000 sq foot home. The entire install was done in one day and we were thrilled with the result. The estimator who came out took pictures and helped decide what the best options were according to our wishes and needs. This is what this company specializes in and they have it down to a science."

"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

Evaporator coils in an HVAC system typically last between 10 and 15 years, which is roughly the same lifespan as the entire AC unit. The longevity of the coils can be affected by usage frequency, environmental conditions, and how well they are maintained. Regular maintenance, such as cleaning and inspections, can extend their durability. If the evaporator coil fails in an older air conditioner, it may be more cost-effective to replace the whole unit rather than just the coil.

When an evaporator coil becomes faulty, it can result in various problems within your HVAC system. These problems could include reduced cooling or heating capabilities due to ice formation and obstructed airflow, along with increased energy consumption and higher bills. Additionally, a damaged coil may lead to refrigerant leaks, which are environmentally harmful and decrease overall system efficiency.

Ultimately, if not addressed right away, a bad evaporator coil can even lead to a complete failure of your HVAC system. That’s why timely repair or replacement is crucial to maintaining your family’s comfort and your HVAC’s efficiency.

Swamp coolers cost approximately 50 percent less to install than central air conditioners and cost less to run. Operation costs depend on the size of the unit and home, your climate, utility rates in your area, and the system’s efficiency. Swamp coolers use 15 to 35 percent less power than air conditioners.

Running a window air conditioner unit costs about $0.06 to $0.88 per hour. Choosing the correct size air conditioner can help it run more efficiently.

Here’s how AC professionals will clean your AC coils:

  1. Unplug the AC unit or turn off the breaker to the unit in your circuit breaker box.

  2. Remove the faceplate.

  3. Spray a vacuum hose attachment or compressed air can to remove debris, dust, dirt, and grime.

  4. Use a soft-bristled fin comb to remove stubborn caked-on debris.

  5. Use the vacuum hose to suck up any extra debris.

  6. Take a coil-safe cleaning solution and spray it onto the coils. Try to choose a no-rinse solution.

  7. Let the solution sit for at least 15 minutes.

  8. Gently wipe away loosened grime and debris with a microfiber cloth.

  9. Reattach the faceplate, plug in your AC system, or turn the breaker back on.
