"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. Very honest and great people to work with! I would highly recommend Adams Heating and Cooling Co., Inc. for any HVAC work in the Capital District of New York State!"

"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!!!"

Heating and Air Conditioning FAQs, answered by experts

Running an air conditioner with mold is not safe because it can spread harmful mold spores throughout your home. Exposure to these spores can trigger various health problems, including respiratory issues, allergies, coughing, wheezing, sneezing, itchy eyes, and a sore throat. It may also aggravate asthma in household members. Continued exposure can increase the risk of more serious illnesses like sinus infections, pneumonia, and bronchitis. If you suspect mold in your air conditioner, you should stop using the system until it has been properly cleaned to avoid health risks and further contamination.

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.

Winterizing can still help you save money on energy costs and help prepare your AC for its work next year when you turn it back on. We suggest planning for at least some maintenance, even if winters are mild in your area.

It depends on the size of the space you’re cooling down. If you’re looking for the most affordable way to cool an entire house over a long period of time, then central air will be more cost-effective. But when it comes to cooling down a couple of rooms or one floor, a window unit may be the cheaper option, with both a lower cost to install and less energy used to run.

There are several steps you can take to prevent your AC drain from clogging. This includes cleaning the drain line at least every three months, changing the filter every one to three months, and getting your AC serviced annually. Also, if any problems arise with your AC, hire an HVAC technician to deal with them ASAP.
