"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!"

"I was delighted with the help given to us at our home by William Nichols and his small, efficient crew at A-1 Heating and Cooling Enterprises. He is both very knowledgeable and a clear communicator--a most helpful combination for someone like me who knows so little about this technology. Mr. Nichols researched what we needed at our home--a replacement for a failing central AC system and a new portable AC unit for the upstairs. He offered information and choices about equipment within our financial means that would work for us. Thus we knew costs for equipment and service as fully as possible ahead of time. He and his crew came on schedule, with their tools and our new system and new portable unit--prepared to dismantle the old system and install the new one. By the time his crew left our home that day, the new equipment was working fine; all paperwork was signed; our bill was settled. We were encouraged to reach Mr. Nichols with any follow-up questions or concerns. He offers 24-hour emergency service. And when he discovered dangerous black mold in the old system--hidden and worsening for years because of an error made long ago by the original installer--Mr. Nichols removed the cause of the trouble and also referred us to an excellent system cleaning service for our home--with whom we're already following up. I do recommend Mr. Nichols and A-1 Heating & Cooling Enterprises to anyone investigating an improvement--sudden or planned--for a home. We're relieved here at our home--and we're cool."

"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!!!"

"The technician, Steve, called me 25 minutes prior to his arrival. He was extremely knowledgeable about my gas fireplace. He vacuumed all areas. He informed me of the condition of the components. I was prepared to ask him a handful of questions that he was able to answer. My fireplace works very well and I strongly recommend using the Chimney Experts."

"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."

He is easy going and hard working. I will definitely be hiring him again."

Heating and Air Conditioning FAQs, answered by experts

Air conditioners can stop working in the middle of the night for many reasons. Your local power grid might shut down late at night. Power surges can also trip your breakers if too much power is being used in the area at the time. If your AC is connected to a digital thermostat, it gets naturally cooler at night, so the outdoor temperature might dip below the automated setting to turn the cooling system off.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

It all depends on the unit’s SEER (seasonal energy efficiency ratio). A higher SEER rating means better efficiency and lower costs for your energy bills. 

Take a look at the product you’re considering purchasing and compare it to other models to decide which one is affordable upfront but will keep your energy costs low over time.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.

An AC inspection costs anywhere from $75 to $200, while a full HVAC system inspection that includes your furnace ranges from $200 to $450. While there's a cost to a home AC inspection, it can save you hundreds or thousands in the long run by catching problems, avoiding breaks, and saving you money on your utility bills.
