"Working with Breathe Cleaner Aire was a fantastic experience. When I made my initial inquiry, Mark called the same day and stated that he was close by and would like to stop over to see the work. He arrived 5 minutes later. Mark noticed from the ground that there was a grate blocking air flow from my dryer roof vent. He said that should be removed. Mark was easy to work with to schedule a time and he actually worked with a few of my neighbors. Mark and Adam arrived on time on the designated date and completed the job in a very short time. Extremely professional, courteous, and went above and beyond to be sure things were clean when they left. They are now my "Go To Company" for any vent cleaning."

Air Conditioning FAQs, answered by experts

A calculation method that your HVAC contractor will use to ensure your system does what it's supposed to is measuring duct output, or its CFM. The calculation requires knowing the cross-sectional area of the ductwork and determining the air speed past any given point within it.

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.

Condensation forms when warmer, outside air combines with cooler air in your ductwork. This can happen when there are leaks in your air ducts, your HVAC system has a dirty air filter, or there’s a lack of insulation around the ducts. To prevent it from happening, replace your HVAC filters as directed. Also, once every five years, hire a local air duct cleaner to clean and inspect them.

A blocked return air vent can cause your HVAC system to work much harder and, therefore, less efficiently. The result is higher utility bills and poorer air quality. A blocked return air vent can also cause unpleasant dust, dander, and odors to linger in your home’s air.

When deciding whether to repair or replace your air conditioner, several factors should be considered. It is generally worth repairing the unit if it's less than 10 years old, the warranty is still active, and you're dealing with a one-off issue. Most central AC units last about 15 years, while window units last 8 to 10 years. If your unit is approaching or has surpassed the 10-year mark and requires frequent or costly repairs (e.g., over $5,000), replacement is often the more sensible long-term investment. For older, inefficient, or out-of-warranty units experiencing multiple problems, replacing it is typically the better choice.
