"Just too expensive for what you get. Feels like a big company nickel and dime move. I get having a trip charge. Which was $109. But then to have the tech who was great btw (not his fault), but was tentative about fixing the problem because of creating more damage. Another $160 for a simple diagnostic charge, again without fixing the problem. I already knew the diagnosis. So he basically did a Band-Aid fix (greased the Knob) and still charged me over $280+ for what equated to be 10 minutes of work. It was ridiculously high for the service provided. Next time I?m going to an independent, local guy."

"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!"

"Wood flooring and so much more. Carpets torn out, subfloors repaired, including work at doors and windows. Impeccable attention to detail. No threshholds, smooth perfect and tight seams from room to room and door to door. I love a crew that doesn't have to hide their transitions under a threshhold. Work ethic--- amazing, here on time, every time, every day. Added on recessed ceiling lighting in 2 rooms and ceiling lights in all rooms. Brutal attic work on over 100 degree day. Seamless experience in every way. They clean up the site at the end of every work day. They haul away whatever needs hauled away. They are friendly, talented, welcome input and do what needs to be done to exceed all expectations. (there were none!). I have more jobs scheduled: decking (including relocating propane tanks), house addition, complete renovation of two bathrooms., fencing. My go to crew for everything."

Heating and Air Conditioning FAQs, answered by experts

Deciding whether to replace just the AC coil or the entire system depends on the age of your unit and the overall cost. Replacing a coil is less expensive than a full system replacement, but it can still be a pricey repair. If your HVAC system is relatively new and still under warranty, or if the replacement cost is significantly lower than a new system, replacing the coil can be a worthwhile investment that restores efficiency and extends the unit's life. However, for older systems (nearing the end of their 10-15 year lifespan) or those with extensive damage, it is often more cost-effective to replace the entire AC unit. Mismatched coils in an older system can lead to inefficiency and future breakdowns, so a full replacement ensures optimal performance and avoids further costly repairs.

Capacitors are the most frequent part of an HVAC system to experience failure. These components are crucial for starting the motors that power the fans and compressor, but over time, they may become worn or fail due to electrical surges or regular wear and tear. When capacitors malfunction, HVAC systems may experience decreased heating or cooling efficiency, or even total system failure. Replacement or maintenance of capacitors is a common requirement for the optimal functioning of HVAC systems.

The simplest indicator is how long it’s been since your last tune-up. You should schedule an annual AC tune-up each spring. Beyond that, there are multiple signs that your AC needs a quick check by a professional. These issues include higher-than-average energy bills, decreased air flow from vents, higher indoor temperatures, and an air conditioning unit that stays on all the time or frequently turns on and off.

There are a few ways to reduce your electricity bills if you use window AC units to keep cool. Set the unit temperature at least 1 degree higher than it is currently to reduce costs. Keep the unit clean for it to run efficiently. You may want to hire a window AC specialist near you to inspect the unit once a year and keep it in tip-top shape.

A home AC unit provides anywhere from one-half to five tons of cooling and requires approximately two to four pounds of refrigerant per ton of cooling. At approximately five to 10 minutes to fill one pound of refrigerant, a home that requires three tons of cooling will take about six to 12 pounds of refrigerant and approximately 30 minutes to two hours to completely recharge the unit.
