"Gregg showed up on time and arrived well prepared to perform the services I requested. He was friendly and cheerful, and completed the routine maintenance of my furnace and the installation of a new humidifier as I requested. I'll be using Adams Heating & Cooling to perform maintenance on my air conditioner and clean the ducts in my home."

"Not only did I receive a call back in less than 10 minutes when calling after hours, it was the owner who called me back. I was offered an appointment first thing in the morning the very next day or an after hours visit that night. I decided to do the morning appointment and Will was there first thing. He was able to assess and fix my problem in less than 30 minutes and was very transparent and affordable on pricing, and was a good with communication. A-1 Heating and Cooling will now be our HVAC care takers going forward!"

"Don Príncipe and Charles are simply the best plumbers you could hire. I'm 60 years old and have hired many for many reasons. I'm blown away by their quality of work and even more important the people they are. These guys are truly dedicated to helping you and will do whatever it takes. I'm very, very impressed and pleased with what they did for me, it was very complex and difficult work."

"We have an old AC unit and it stopped working so I call around to get some quotes for a new unit. Yancyâ s came and was the only company to take the time and look over the old beat up unit and managed to get it up and running , he could have easily just said itâ s junk and need a new one. The honesty and helpfulness was so good to see !! When the unit does finally go Yancyâ s will be my first and only call. Keep up the good work ð ð »"

Heating and Air Conditioning FAQs, answered by experts

You need to know the square footage of your home first. Multiply that number by 20, which will get you the BTUs (British Thermal Units) needed to cool your home efficiently. Homes up to 1,000 square feet usually need a 1.5-ton unit; homes 1,000 to 1,200 square feet usually need a 1.75-ton unit, and homes 1,200 to 1,400 square feet usually need a 1.9-ton unit. Talk to a local pro for more specific advice on your home. 

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.

If the air coming from your AC unit is cool but never quite cold, there are a few reasons this might be happening. For starters, it could signal that your refrigerant levels are low. If there are no other indications of this particular issue, like hissing noises or frozen refrigerant lines, anything from dirty filters to damaged condenser or evaporator coils could be responsible for the problem.

When faced with HVAC issues, it's best to begin by ensuring the thermostat settings are correct for either heating or cooling. If the system isn't responding, check the thermostat for proper function and power supply. It's also important to examine air filters, as clogged ones can decrease performance. Confirm the power supply to the system by checking the circuit breakers and fuses. If these basic steps fail to resolve the issue, contact an HVAC professional for a more detailed diagnosis and repair.

If you know how to identify supply and return ducts, you’ll find that only the supply ducts will have dampers. Although your return ducts can have dampers, it’s not common. If you have one return duct that is pulling in too much air, adding a damper to it can help with overall system performance. However, dampers on return ducts are not a necessary addition for most homes.
