The technician discovered that the A/C unit had frozen, and so was not operating; he explained the issues, and suggested that we make sure none of the ducts were blocked and then simply let it thaw so as to not damage the unit. This is what we did, and the problem was successfully resolved.

Air Duct Cleaning questions, answered by experts

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.

Yes. Return air vents are responsible for gathering and pulling in the warmer air. Once they draw it in, your system conditions the air by removing the warmer molecules from it, allowing your air conditioner to dispense the cooler air back into your home. Not only does this create a more comfortable environment for you, but it also keeps your air conditioner from overworking, resulting in lower energy bills.

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.

Yes, a bowl of vinegar can absorb smoke. If you want to use this method to reduce the smoke smell in your house, all you have to do is leave a bowl (or multiple bowls) of white vinegar out overnight. Alternatively, you can use bowls of baking soda, coffee grounds, or activated charcoal.

Yes, rust in ductwork is bad if it’s left untreated. Mild rust can be removed before it causes any significant damage. However, if you ignore rust, it can affect the structural integrity of the ductwork, and you’ll eventually need to replace it entirely. In addition, rust-causing moisture in ducts can also cause mold growth.
