"Jeremiah and his crew did a fantastic job. They arrived on time, worked very hard in the small hot attic space, did not waste time and were very professional.

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

Evaporator coils last between 10 and 15 years before they need to be replaced—as long as you stay up-to-date with routine maintenance. This is roughly the same life span as most AC units. So, if you have an older air conditioner and the evaporator coil goes out, it might be more cost-effective to replace the whole unit rather than just the coil.

Dirty filters are almost always the cause of poor airflow, so they should be regularly cleaned and then replaced as needed. The fan blades can also get dirty, so they should be cleaned when the unit is turned off. Make sure that the outdoor area around the back of the unit is unobstructed. Trees, shrubs, trash, and other objects could be too close to your unit.

Signs of a damaged evaporator coil include warm air from vents, frequent starts and stops without proper cooling, failure to turn on, refrigerant leaks, and unusual noises. If you suspect issues with your AC system or its components, it’s best to call an AC repair technician for proper diagnosis and repairs.

Turning off your AC may temporarily stop your unit from leaking water unless the leak is from a thawing coil that continues to thaw after the system is shut off. Regardless, it helps to discontinue use of the unit if it has a leak in order to figure out what’s causing the issue.

When your AC contactor goes bad, you might hear chattering or buzzing noises coming from your air conditioner. You may also notice that your AC is running but isn’t cooling your home. In some cases, your air conditioner might not even turn on at all. There could also be physical damage, discoloration, or corrosion around the contactor.
