My name is Beth Finlayson and I am the owner of this electrical business. I run a small business out of Woburn MA and have been in the trade for over a decade now. My company always strives to be prompt, professional, and yet still maintain reasonable rates.

"Beth did a great job installing new motion sensor lights on my property. Her customer service and communication was excellent. We arranged the entire job via text and email. She was very responsive to my questions and gave great advise. I will hire her again the next time I need a licensed electrician."

Heating and Air Conditioning questions, answered by experts

A dirty air conditioning coil can cause your unit to work overtime, leading to reduced efficiency, higher energy use, more wear and tear, and possible ice buildup. If the coils corrode, refrigerant can leak, causing damage, possible mold growth, and an expensive repair bill. By cleaning your AC coils once a year, you’ll have a more efficient unit that’s likely to last longer.

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.

To make the most out of your AC, consider implementing the following best practices: 

  • Choose the right size AC for your home to ensure your unit runs as efficiently as possible.

  • Choose a window with shade, as direct sunlight can cause your AC unit to overheat. 

  • Clean or replace the filter at least every two months. 

  • Inspect the AC’s fan and straighten it if necessary. 

  • Discontinue use immediately if you suspect a malfunction, as running the AC while broken can lead to significant issues. 

  • Turn off (or adjust the temperature) when you leave the house.

Unlike other types of air conditioning, portable units don’t require venting or any other associated parts like hoses. For that reason, they don’t function the same as their counterparts, but will do a similarly good job of cooling down small spaces and won’t require any installation or much maintenance.

You should only run your dehumidifier in warmer months, such as spring and summer, to get the best performance out of your system. The air gets drier when temperatures drop in the winter months, creating less of a need for a dehumidifier. However, when to run a dehumidifier will depend on your local climate.
