"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."

Hi, I’m Kaylee! I’m a dependable, hardworking, and detail-oriented cleaner who takes pride in creating clean, comfortable, and welcoming spaces.\n\nI have some experience with vacation rental turnovers, office cleaning, and regularly cleaning and sanitizing a childcare environment. I’m organized, reliable, and comfortable working independently, and I understand how important it is for a vacation rental to be thoroughly cleaned and ready on time for the next guest.\n\nI’m currently growing my independent cleaning business and would love to connect with local vacation rental owners and property managers. \n\nI’m looking forward to building lasting relationships with property owners and providing reliable, consistent service they can count on!

Small jobs welcome

I graduated from Maine Maritime Academy and currently do have a day job but am looking for some side jobs for extra money. I built an addition on my house and found that I have quite a bit of talent in all areas of a house. I’ve installed my own heat pumps in my home, I’ve poured slabs, did all of the plumbing, electrical, insulation, drywall, flooring, trimming, doors etc. I learned a great deal and would like to put that knowledge to use.

Heating and Air Conditioning FAQs, answered by experts

Yes. It's normal for the AC compressor to cycle on and off intermittently in dry mode as it maintains the desired humidity level. The compressor cycles to prevent over-dehumidification and to maintain a comfortable indoor environment. This cycling behavior ensures efficient operation and optimal humidity control, contributing to the overall effectiveness of the dry mode function in your AC system.

It’s never a good idea to run your AC without a filter, even just for a night. The filter defends your HVAC system from the dust, dirt, debris, and other grime in your home. Without a filter, those contaminants are more likely to get inside your system and potentially damage it. 

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.

When faced with HVAC issues, it's best to begin by ensuring the thermostat settings are correct for either heating or cooling. If the system isn't responding, check the thermostat for proper function and power supply. It's also important to examine air filters, as clogged ones can decrease performance. Confirm the power supply to the system by checking the circuit breakers and fuses. If these basic steps fail to resolve the issue, contact an HVAC professional for a more detailed diagnosis and repair.

You should clean your air conditioner at least once per year, but you may need to clean your whole HVAC system (including the air ducts) more often. According to the National Air Duct Cleaners Association, you may need to clean them more frequently depending on factors like whether you smoke, have pets, or have allergies.
