"Terry Hobbs is a great responsive Project coordinator. The entire Adams team was great! They came out quickly and help diagnose and got me a new furnace at a reasonable price.

"Early Summer our A/C system was not working properly. Kenny and several employees responded promptly and repaired several issues with our system and got it working. They returned with a part they ordered and installed it the next day. All working fine now."

"Integrity, Service, Professionalism & “Technical Know How” - if you are looking for this in a HVAC company – FloBros should be your go to service provider. I’ve worked the Capital District’s Top Tier providers & they fall short where FloBros excels. When I looked to the “big guys” for a simple service request they immediately “blew up” a small request into a new installation. FloBlos was sharp in trouble shooting & to the point in options, I’ve used them multiple times now & will continue to do so in the future. Look no further than FloBros for your HVAC needs!!!"

"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!"

"The owner of the company, Jeremy Morin, was prompt and the furnance was cleaned in a timely manner. Also, he followed up with an email advising me on quotes for a new furnance as well. I will definitely continue my services with this company, and will be referring his business to my family and friends as well. I would like to mention Jeremy is a Veteran as well, and offers discounts to service men and women. Thank you again for a job well done."

Heating and Air Conditioning FAQs, answered by experts

Yes, a dehumidifier and air conditioner can be used simultaneously in a home. A dehumidifier can bolster an air conditioner’s efficiency. Typically, a dehumidifier is used when the air conditioner alone cannot keep a home’s humidity levels at a comfortable indoor humidity level, which should, ideally, be between 30% and 50%.

Many HVAC companies offer free quotes and free estimates for repairs and new HVAC systems. Others offer low-cost quotes or apply the cost of the estimates or diagnostics to your final bill if you hire them. Be aware that some companies advertise free HVAC quotes and recoup the costs by charging more for their services. Free HVAC quotes are never truly free—they cost the company time and effort—so be a good customer. Also understand that you may end up paying for free quotes in another way if you don’t hire a reputable company.

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.

Yes, it’s important to turn off your AC sometimes to give it a break and prevent it from freezing up. If your AC runs all the time, your system’s parts will wear down quicker, which may mean that you need to replace it sooner. Plus, using your AC constantly uses more electricity and leads to higher energy bills.

You should know the main components of an air conditioner: the condenser coils, evaporator coils, drip pan, AC filter, ducts, and refrigerant. Each part plays a key role in the performance and safety of your AC system. When tracking the source of AC issues or odors, it helps to know where to look. Your outdoor unit houses your condenser coils, fan, and compressor. Your indoor unit houses your evaporator coils, drain lines, and filter, and it connects to your ductwork.
