Frequently Asked Questions
Quick answers to common HVAC questions
In Phoenix, we recommend at least once a year—ideally in spring before the brutal summer heat arrives. The extreme temperatures here put more stress on systems than in milder climates. Regular maintenance catches small issues before they become expensive failures.
Several things can cause this: a dirty air filter restricting airflow, a frozen evaporator coil, low refrigerant, a failing compressor, or a faulty capacitor. Our diagnostic service ($129) identifies the root cause so you know exactly what you're dealing with.
In Phoenix, we recommend checking monthly and changing every 1-3 months depending on the filter type and your home's dust levels. During peak summer when the system runs constantly, filters clog faster. A dirty filter is the #1 cause of preventable A/C problems.
