"Sean Gilhooly was excellent! He was able to repair my Fujitsu ductless mini splits when other companies said the entire AC would have to be replaced. Sean saved me from having to spent over $10,000! He was able to find the leak in the refrigerant pipping, replace the part, test the system, and put new refrigerant in the system. He was efficient and reasonably priced. If I have a need for AC service in the future, Sean will be the guy I call. I highly recommend FinMar Comfort, LC for AC needs!"

"Way beyond my expectations! Professional on every level from covering their shoes every time they went in and out, thorough problem investigation, courteous and great explanations throughout the process, reasonable and fair prices, solid install and equipment. What's more, even long after I paid in full, they continued to go to bat for me with National Grid who identified a problem on their end and promised repeatedly to fix it but as of this comment, has not yet done so. 6 stars for Mr. Electric if I could!"

"Excellent Service! I highly recommend the Capitol Region Plumbing and Heating Services LLC! Avi, and Sean came to my home immediately when I needed their help with bathroom plumbing and a water pump system. They were courteous, knowledgeable, and thoroughly evaluated the problems. Their excellent assessment and quality of work were evident as I looked at their pictures of before and after replacements of PVC pipes for main sewer lines, sink and shower drains, and water lines for the toilet. Also, Avi and Sean installed a new well pump and pressure tank system. They even came to my home on a holiday to assure me that I'd have water. As true professionals, Avi, and Sean are efficient, punctual, and reputable. Their work ethic is commendable and gracious manners are exceptional. This was an incredible plumbing service that everyone expects and appreciates!"

"Pete and Isaiah did a wonderful job. They were here close to 6 hours dealing with duct work and dryer vents in my old (1840) house. Also cleaned the airconditioner condenser. They educated me about all the tasks they were working on, responded to my questions and showed me the result of cleaning they had done. I feel really good about the work they did and heartily recommend Duct Kings. Dottie"

"We had a new furnace combi installed in our basement and We were exceptionally impressed with Kevin and Aaron and the 2 other gentlemen who helped. They were considerate and cleaned up after each work day. We engaged in a little conversation and both these guys were so nice! They went out of their way to do things right."

Heating and Air Conditioning FAQs, answered by experts

AC capacitors have a wide lifespan, ranging from five to 20 years, with an average of about 10 years. Many capacitors will last for the entire life of the air conditioning unit, and most homeowners only need to replace one once. A capacitor should only be replaced if an HVAC professional diagnoses a problem with it. Premature failure can be caused by overheating, power surges, or short circuits. You can help extend the life of your AC capacitor by scheduling regular AC maintenance each year.

While personal preferences widely vary, sleep experts say the best temperature for sleeping is between 60 and 67 degrees Fahrenheit rather than 78. If you do choose to sleep with your AC unit tuned to 78 degrees, you might want to use only a sheet or light blanket rather than a comforter. You might also consider installing a window unit in your bedroom so that you can be cooler in bed without wasting energy cooling the whole house.

You can air condition your Arizona room by extending your home’s existing HVAC system or adding a ductless mini-split system. Arizona rooms that have full windows rather than screens only are a better choice for air conditioning—screens will let the cold air out as fast as the air conditioner can make it. 

When first installed, flex ducts shouldn’t cause airflow problems in your home. However, because flex ducts aren’t the sturdiest and require extra support, they lose their durability over time and begin to sag, which can inhibit airflow down the road. Also, if your flex ducts aren’t tight enough, your HVAC could work twice as hard for the same air pressure. If you’re worried about the airflow in your home, a rigid duct may be your best bet.

No, it's not advisable to only replace the outside AC unit connected to your system. AC units are designed to work as a cohesive system, and older units work differently than newer units. Therefore, replacing only one component can lead to incompatibilities that affect the system’s performance. Replacing one component can void your warranty, costing you money for repairs.
