Air Duct Cleaning questions, answered by experts

When your HVAC system is loud, a few different causes are possible. If you have loose connections or bolts in the hardware, they can rattle as the system runs and vibrates. If you have an extremely dirty furnace filter, it could cause the system to generate noise. More commonly, an excessively loud HVAC system indicates a malfunction in the system. You may have a blower motor that is close to failing or a compressor that is breaking down. These issues require an immediate inspection.

Excessive humidity in a room often manifests through visible signs like condensation on windows or walls, a musty or damp odor lingering in the air, peeling wallpaper or paint, and the presence of mold or mildew. Experiencing discomfort due to a consistently clammy or sticky feeling can also indicate high humidity levels.

The cost of annual maintenance depends on the type of HVAC system you have. AC service typically costs an average of $200 but ranges from $100 to $550. If your system needs repairs, the price will vary significantly depending on what needs fixing. However, addressing the issues as they arise can prevent further damage to your unit and keep it operating efficiently for much longer.

Figuring out why you have a musty smell in your house is the first step to getting rid of it. Mold or mildew is most likely causing the unpleasant odor. People use these terms interchangeably, but they’re actually different.

Mold is a fungus that loves to grow in moist, humid places. It’s typically black or green and has a raised, uneven texture. Stay vigilant for signs mold may be growing in your home.

You’ll find mildew growing on your shower walls and in your bathroom’s nooks and crannies. It’s a specific type of mold that grows flat. Mildew is usually white, gray, or yellow.

Mold in your air conditioner isn't a good thing, as it can be harmful to your health. If the mold travels through the ductwork or is blown out of the A/C, you and your family can inhale mold spores and develop respiratory illnesses and other problems. Preventing mold from growing in the air conditioner will help protect your health.
