How often should I replace my HVAC filter?

Changing your HVAC filter on a regular basis is critical for keeping your system running efficiently and providing high indoor air quality. It is generally advised that you change your filter every 1 to 3 months, depending on the circumstances. For typical houses without pets or allergies, replacing the filter every 90 days is usually adequate. However, if you have dogs, allergies, or someone in your family who suffers from respiratory problems, replace the filter every 30 to 60 days.

Homes with several pets, or in places with high amounts of dust or pollution, may necessitate more regular cleaning. Furthermore, during high consumption seasons such as summer and winter, when your HVAC system is used more frequently, it is recommended that you check the filter more frequently. A blocked filter can limit airflow, forcing your HVAC system to work harder, resulting in increased energy costs and extra wear & strain on the equipment.

Regularly cleaning your filter helps improve indoor air quality by collecting dust, pollen, and other airborne particles, which is especially helpful for allergy sufferers. A clean filter ensures that your HVAC system performs effectively, lasts longer, and keeps your house pleasant all year round.

What may harm your HVAC system?

Several things might cause damage to your HVAC system, resulting in lower efficiency or expensive repairs. One typical concern is forgetting to perform basic maintenance, such as replacing filters or scheduling yearly inspections. Dirty or clogged filters can limit airflow, requiring the system to work harder and potentially causing overheating or mechanical failure.

Improper installation is another key source of harm. If the HVAC system is not properly designed or built, it may result in poor performance, frequent failures, and increased energy costs. Poorly maintained ducting can also cause harm, since leaks or blockages limit airflow and force the system to work harder than necessary.

Overuse is another source of HVAC damage, particularly during severe weather. Running your system continuously without allowing it time to rest can cause wear and tear on components, reducing its lifespan. Refrigerant leaks can potentially cause system damage, resulting in cooling concerns and compressor strain.

Finally, external events such as power surges, bug infestations, or exposure to harsh weather conditions can cause damage to your HVAC system. These problems may be avoided by covering your outside unit in adverse weather and providing proper electrical protection. Regular maintenance and early repairs are critical for avoiding significant damage.
