"It was covered under warranty. They actually installed our HVAC and it just wasn't cooling and it was a real simple thing that he was able to fix me up with. I have know them and used them for a long time. They are always prompt. They are very professional in what they do. They pick up after themselves. Very helpful in the information that he provides and making sure that any issues we are dealing with, he takes care of."

"All Comfort Today was impressive from the beginning to the end of my project. Bryan Swords canned to my home first and gave me a detailed assessment of my current AC system. Not only did he provide a replacement quote, he also got me two considerable rebates. He provided a detailed package that would replace my zone system and showed me how it would save money. Brian followed up with me to answer questions and came to my house again. The team of installers were professional, clean, and thorough. I am extremely happy with my selection of All Comfort Today, LLC for installing my new Lennox System."

"We purchased a new Clayton home in late 2023 and everything seemed good at first. After several times over a year of having HVAC techs from Clayton come out for a cooling issue, eventually the warranty ran out on the AC. Then we had another supposedly reputable HVAC company come out and said it was a lot of issues outside and would cost almost $2000 for a repair that may or may not work. We went thru Angis list and got in touch with Quality Air. The tech came out and went thru our system and located the issue inside that was never installed from the Clayton homes store. Nathan had our system up and running and has been cooling excellent ever since. Before, our system had a very hard time keeping up with the selected temp.. but now we sit in cool comfort and it has never ran so great. Thank you Nathan, and thank you Quality Air!!"

Heating and Air Conditioning questions, answered by experts

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.

Most HVAC companies recommend against setting your AC below 70 as it could freeze up the system and cause more problems. Regardless of how hot it is outside, there is generally a 20 degree difference between the outside and inside temperatures, so even if it’s 100 degrees outside, your AC will likely not be able to cool your home to 70 degrees.

Ideally, an AC system should never need more Freon (a popular refrigerant) because it circulates in a closed loop. However, refrigerant leaks are not uncommon and may occur gradually over 5 to 15 years. If your system has a leak, it will need to be topped up in a process known as an AC recharge. Signs of a refrigerant leak include weakened AC performance, increased humidity in your home, higher utility bills, and a hissing sound from the unit. The cost of an AC recharge will depend on the size and type of your AC unit, as well as the type of refrigerant it uses.

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. 

Most HVAC surge protectors last about three to five years, depending on how often your home experiences blackouts or brownouts. If your unit is susceptible to more frequent electrical surges, consider replacing your surge protector every two years. Consult your HVAC professional to determine when and how often to replace your HVAC surge protectors.
