Annual maintenance keeps the HVAC system in your Catalina Foothills, AZ home in high-performance mode. Maintenance includes regularly changing your filters between service visits. Running your unit with a dirty filter can have disastrous consequences. If ignored long enough, a clogged air filter can bring down your whole system. Before that, it can cause problems that require HVAC repair. Be alert for these signs that your filter may need replacement:
The Air Filter Looks Dirty
The frequency of filter changes varies from house to house. Your filter may need changing every two weeks. Your neighbor’s filter may need replacement every six months. How long a filter lasts depends on everything from the number of pets in your home to the type of air filters you use. The best policy is to check your filter monthly and replace it when you can’t see filter material through the dirt.
Utility Bills Are Spiking
Your system has to work extra hard to push heated or cooled air through a dirty filter. That increases energy use and utility bills. Clogs impede system performance too, so your home may feel uncomfortably hot or cold.
There Are Operational Problems
Dirty filters can cause your air conditioner to overheat or to freeze up. Clogged filters restrict the airflow coming through the vents. A blocked filter can also cause your system to run constantly or to frequently cycle on and off.
Indoor Air Quality Seems Off
Filters are designed to capture airborne contaminants that can cause flu-like symptoms and make allergies and respiratory conditions worse. When an HVAC filter is filled to capacity, it can’t prevent dirt, allergens and other airborne toxins from circulating throughout your living space. You may feel ill, or your home may be exceptionally dusty.
