Did you know that nearly 70% of Americans own their home? Whether you own your home or are renting a property, keeping up with maintenance is critical. AC repair and HVAC maintenance are some of the most important details to focus on.

But how do you know when maintenance might mean a new AC installation? One way to keep your air running cleanly is to conduct regular air duct cleaning.

If you’re curious about the benefits of cleaning air ducts, we’re happy to help. Read on to learn how to know when it’s time to clean your ducts.

Regular Maintenance

The first way to know how to clean your air ducts is simple: time. Your air ducts should be cleaned at a minimum schedule.

Events may happen that require you to clean your ducts more frequently. Otherwise, you should clean your ducts at least every three years.

Some factors may alter this number. For example, smokers or pet owners may have pollutants get into their ducts. If you fit either of these demographics, you should clean your ducts more frequently.

Changing Homes

Have you recently purchased or moved to a new property? It’s difficult to know how the previous tenants kept up with maintenance.

If possible, speak with the previous tenants and see when the last maintenance was. Did they have the vents cleaned a few months ago? You should be in the clear to avoid another air duct cleaning.

Are they unsure of when the last time was? You can safely assume it’s time to clean them again.

Visible Mold

Vents are hotbeds for mold, particularly in the summer. Changes in temperature can cause condensation, which will help mold grow.

If you spot mold on your vents, it’s likely grown through your air ducts. You should schedule an inspection or contact the National Air Duct Cleaners Association for input. There’s a good chance it’s time to have your vents and air ducts cleaned.


Have you noticed pests around your home? Rats, mice, and insects like cockroaches or ants often use vents to travel.

While in your vent, they also may leave dander, waste, and dirt. The vents then push this material through your home when the air comes on. Handle the infestation and have your ducts cleaned.

Allergy-Like Symptoms

Finally, allergy-like symptoms imply a heightened amount of dust and dander in the air. If you’ve been coughing, sneezing, or having irritated eyes, it may be from dirty vents.

Should you experience these symptoms for a prolonged period, have your vents inspected. If they are in need of cleaning, having them serviced may improve your health.

HVAC Maintenance and AC Installation

HVAC systems are complex and often slip our attention. After a new AC installation, it’s important to keep up with maintenance so you don’t need expensive AC repair services. Keep your ducts inspected and maintained to prevent dust, dander, and damage.
