"We hired Breathe Easy Air Duct Cleaning to clean out the dryer vent. He was very prompt in contacting me back and got us right on the schedule. He was on time and very pleasant to work with. He did his job quickly and efficiently. We were so pleased that we want him to do some other jobs for us and we already have it on his schedule."

"They fixed my breaker and installed LED lighting, fire detectors in 3 bedrooms in a 6 hour period. Very professional and they cleaned up perfectly afterwards. They could have rushed through but approached me to ask if I wanted dimmer switches and what color. Great work, old school quality customer service."

"Dillon was a great guy and worked fast and efficient. My house is 50 plus years old and the duct work had never been cleaned. Post the work, the house even smelled better. I am in the middle of a complete remodel and living in the house. I had all 11 vent grilles removed -(saved Dillon a pile of time not having to remove and re-install) and I would have thought a discount would have been in order."

Heating and Air Conditioning questions, answered by experts

Freon will go in the refrigerant lines near the back of your AC unit. Look for small ports with caps on a thin copper line—the Freon goes into those ports. You are best off hiring a licensed HVAC professional who can complete the job safely and correctly.

Whether an HVAC damper should be open or closed depends on the season, the zone it controls, and the temperature in that zone. In the summer, open upstairs dampers and close lower-level dampers to get the most efficient cooling possible. In the winter, do the opposite. Cool air will naturally flow down to lower levels, while warm air will rise. This keeps your system from working harder and helps prevent common AC problems.

Yes, mini-split systems are generally less expensive to run than central air conditioners and are significantly more energy-efficient. Because mini-splits do not rely on ductwork, they avoid the energy loss associated with ducted systems, allowing cooled or heated air to reach its destination more efficiently. Additionally, they offer zoned control, meaning you can run units in individual rooms and turn them off in unoccupied areas. This capability can lead to energy savings of about 30% compared to a central air system, resulting in a lower monthly energy bill.

If there’s a freon leak in your home’s AC unit, it will cause the system to work overtime to cool the house. That issue will result in higher energy bills and it will take much longer for cool air to disperse throughout the home. If your system has a freon leak during the summer, it can make hot days miserable. That’s why it’s important to hire an HVAC professional to resolve a freon leak as quickly as possible.

The American Society of Heating, Refrigerating, and Air-Conditioning Engineers, or ASHRAE, sets the standard guidelines for air changes per hour in homes and businesses. The International Residential Code, or IRC, also sets ACH requirements for residences and bases those requirements off of ASHRAE standards plus climate specifics related to your location.
