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

A frosty expansion valve that isn't blowing out cool air is a sure sign that it’s time to replace it. It might also be time to replace the TXV valve if your AC unit switches off soon after turning on or if you have poor airflow in your home.

A window AC unit is not completely silent. You’ll hear the sound of air blowing, and if you put your ear right up next to the unit, you may hear a slight hiss or gurgle as the refrigerant flows through the system. That said, if your system is making a running water sound, a loud banging sound, a grinding sound, or physically vibrating, you may be facing an issue or malfunction with your AC unit.

Yes. In fact, not only are AC tuneups worth it, but they’re actually necessary to keep your air conditioner in good condition, improve its efficiency, and potentially prevent major damage. Experts recommend getting a tuneup at least once per year. In most cases, you’ll want to schedule it during the spring so that you can address any issues before the hottest months of the year.

Signs that your air conditioner capacitor is bad or failing include a range of symptoms. The AC unit may not turn on at all, or it might struggle to start before shutting down randomly or in the middle of a cooling cycle. You might hear a humming or banging noise when it attempts to start, or the compressor might hum without the unit actually running. Other indicators include a smell or smoke coming from the unit, the blower circulating room-temperature air instead of cold air, and an unexpected increase in your energy bills.

You might notice that your air conditioner isn’t running as effectively as it once did. Specifically, your AC unit could take longer to cool your home, or it might struggle to remove humidity from the air. Higher utility bills and hissing sounds coming out of your AC could also indicate a leak.
