"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

The $5,000 rule for HVAC systems helps homeowners decide whether to repair or replace an AC or furnace. Take the quote for the HVAC repair cost and multiply that by the age of the HVAC system. If the total is higher than $5,000, it’s more cost-effective to replace the system. If the total is lower than $5,000, consider repairing the system.

While most air conditioners can last between 10 and 20 years, they will only last this long (or longer) if properly taken care of. Routine maintenance and inspections help keep your AC unit running in tip-top shape but understanding what factors will decrease its lifespan will also help keep your unit running cool.

Some things that shorten your AC’s lifespan include:

  • Extreme outdoor conditions, like high humidity or extensive salt spray 

  • Improper installation

  • Extended run times, either by the unit being too small or the thermostat setting too low

  • Not performing required maintenance

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.

If your AC runs constantly, it could be due to a number of things, including a faulty thermostat, incorrect temperature settings, or broken equipment. Alternatively, you might have an airflow problem (for example, blocked vents or leaky ductwork). Either way, an HVAC pro can identify the specific problem and fix it for you.

Air conditioners and dehumidifiers are actually quite similar, though they perform different jobs. Dehumidifiers reduce moisture in the air, while air conditioners work to cool the home. A good central AC unit will naturally perform a certain level of dehumidification due to its design, but it will not be able to handle excessive levels of moisture.
