"?????⭐⭐⭐⭐⭐ I called in LATE on a FRIDAY afternoon. APRIL enthusiastically answered, FIRST ring, & I explained the awful noise from my sump pump. She got me on the next day's schedule. Saturday! I gave her the specs of the unit & she calmly took notes for the technician. Jimmy texted on his way, arrived timely & had all the necessary parts stocked in the truck! He completed the changeout in record time & accepted credit card payment. The entire process couldn't have went any smoother! The new Zoeller unit runs so quiet, I don't hear it at all in the house. After seeing the shooting plume of water, I informed Craig the SM & his followup exceeded my expectations. Great team to work with; excellent service, fair price! Ten Stars!"

Air Duct Cleaning questions, answered by experts

Dirty filters are almost always the cause of poor airflow, so they should be regularly cleaned and then replaced as needed. The fan blades can also get dirty, so they should be cleaned when the unit is turned off. Make sure that the outdoor area around the back of the unit is unobstructed. Trees, shrubs, trash, and other objects could be too close to your unit.

The number of return air vents a house should have depends on its overall square footage. You'll need one supply vent and one return vent for every 100 to 150 square feet of living space. This means that, ideally, there should be at least one return air vent in every room. However, if the room is 100 square feet or larger, it's better to have two or three. A 2,000-square-foot home should have between 13 and 20 return air vents, in total.

Forced air systems should be inspected and maintained by a professional every year. A forced air technician will check the furnace, ductwork, and other key parts of the system to ensure it is operating efficiently and safely. Properly maintaining the system can reduce health risks and prolong its lifespan for years to come.

Vents may blow air even though the air conditioning system is off because of the pressure difference between indoor and outdoor air or drafts from leaky ducts. Check for leaks or drafts in the ductwork or around windows and doors.

The only immediate step you need to take after the air duct cleaning finishes is changing your furnace filter. It’s likely to accumulate some dust and debris during the cleaning process. There’s no need to replace the filter before the cleaning starts, as a dirty air filter won’t affect the cleaning process. Regularly replacing your air filter is one of the best steps you can take to keep your air ducts clean in the months after a pro cleans them. The pro should clean up any mess left behind and reattach all the grates.
