"I hired Capital Heating &Cooling for air duct cleaning. The technician, Garrett, was very friendly, explained everything he was going to do, and clean up was great. The one thing I didn’t like was the aggressiveness of their sales team. They continue to text, call, etc. until they hear from you."

"Josiah did a great job on my dryer vent duct work. This ductwork was behind the wall and only accessible from the vents. Everything looked like metal semi-rigged duct work from what could be seen from both ends. I started cleaning the ducts myself then I noticed insulation coming out of the vents instead of dryer lint about midway down the ducting. Thats when I called home advisor and was connected with Wisconsin Natural Air Duct Cleaning. The material hidden in the wall was plastic flex ducting that had began to fail due to age and isn't suited to cleaning anyway (should just be replaced.) Josiah did a great job replacing the plastic with metallic flex ducting. I'll use WNADC again for some future projects."

Air Conditioning questions, answered by experts

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.

They can, but it’s not as common. Window AC units are much smaller than whole-house systems and less likely to develop refrigerant leaks or similar issues. As a result, you will rarely need to add a new refrigerant, limiting overcharging problems. However, it’s still important to leave refrigerant management in the hands of professionals when window units need work.

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.

On average, an AC unit lasts between 10 and 20 years. However, the specific lifespan depends on the type of unit, how often it's used, the local climate, and the quality of maintenance. Central AC units typically last 12 to 17 years, while window units have a shorter lifespan of 8 to 10 years. Portable AC units last about 5 to 10 years, and ductless mini-split systems can last up to 20 years. To extend the life of your AC unit, it's important to perform regular maintenance, such as replacing filters, cleaning coils, and scheduling annual professional tune-ups.

You should clean your air conditioner at least once per year, but you may need to clean your whole HVAC system (including the air ducts) more often. According to the National Air Duct Cleaners Association, you may need to clean them more frequently depending on factors like whether you smoke, have pets, or have allergies.
