After washing the windows with Windex and wiping everything down with a dry towel, the car was free from odor and looked and smelled clean and fresh! Fantastic Products!!!"

"This was the most money we have ever paid anyone to do anything...ever. The Sheridans had our trust throughout the entire process. They gave an affordable quote and did awesome work. They cleaned up during each stage of the project and always communicated well with me about timing and issues that came up. Our garage dimensions were awkward and not a perfect rectangle by any means - these guys had to craft a kit of workarounds for irregular shapes and curves. Todd and Luke are good human beings with positive attitudes, and care about their integrity and their work. I hope to use them in the future."

Air Duct Cleaning questions, answered by experts

You may occasionally notice less air movement from your home’s furnace and air conditioning system. Cleaning air ducts can help with airflow through the HVAC system. However, quite a bit of dust and debris inside the ducts wouldn’t restrict airflow enough that you could feel it. As a first option, try changing the furnace filter to improve airflow.

There are several signs that your ducts might be clogged, such as encountering more dust in your home, dirty air vent covers, airflow and temperature changes from room to room, noticeable mold growth, and higher energy bills. If you notice these signs, shine a flashlight down your ducts and inspect for clogs or blockages.

You can do simple maintenance to keep it clean and operating in peak condition. Start by replacing the furnace air filters as directed–often, this is once every month or every three. Next, clean your air vents once a month, as they can help you see how much dirty air filters through. If you notice them becoming dirtier, you should have your ducts cleaned. With flexible ducting being more susceptible to tears, you’ll want to hire a pro to do the work for you. 

If you notice increased energy bills, poor airflow, or frequent HVAC system issues, a professional assessment is advisable. Technicians can identify duct leaks or inefficiencies that require updating or maintenance.

Your HVAC manufacturer will give you instructions on how often you should service your system. Have your unit professionally serviced at least once a year when in doubt. 

Heat pump systems are different because they provide heating and cooling solutions for your home. In this case, you should have it serviced at least twice a year.
