Questions and Answers
How often should I change my air filter in Keller to combat our local dust?
In Keller's dusty environment, we recommend checking your standard 1-inch air filter every month and replacing it at least every 90 days. For homes with pets or higher occupancy, changing it monthly is best to maintain airflow, efficiency, and indoor air quality.
Why is cleaning my outdoor AC unit's coils so important for Keller homes?
Our local dust and debris quickly coat the condenser coils, acting like insulation. This forces your AC unit to work harder and longer, driving up energy bills and risking premature failure. Regular professional cleaning restores efficiency and is key to preventing costly repairs.
What are the signs my HVAC system is struggling with Keller's dust and dirt?
Watch for reduced cooling power, longer run times, higher energy bills, and unusual noises like straining or rattling. Ice buildup on refrigerant lines or weak airflow from vents are also clear indicators your system needs attention to address filter or coil issues common here.
