Air Conditioning FAQs

Warm air from your AC usually indicates low refrigerant, a dirty filter, a frozen evaporator coil, or thermostat issues. Start by checking your filter and thermostat settings. If the problem persists, call a professional to diagnose the issue.

Most filters should be changed every 1-3 months. During heavy use (summer), check monthly. Homes with pets, allergies, or high dust may need more frequent changes.

This could indicate low refrigerant, a dirty condenser coil, a failing compressor, or frozen coils. Check that your outdoor unit is running and clear of debris. If the issue continues, professional diagnosis is needed.

AC repairs typically range from $150-$600 for common issues. Major repairs like compressor replacement can cost $1,500-$3,000. We provide upfront pricing before any work begins.

With proper maintenance, air conditioners typically last 15-20 years. Heat pumps generally last 10-15 years. Regular maintenance extends system life.

For the Bay Area climate, we recommend at least 16 SEER for good efficiency. Higher SEER ratings (18-26) provide greater energy savings but cost more upfront.

AC units are designed for outdoor exposure and generally do not need covers. Covers can trap moisture and attract rodents. If you want protection, a top-only cover is acceptable.

Short cycling can indicate an oversized unit, low refrigerant, a dirty filter, or thermostat problems. This wastes energy and wears out your system faster. Professional diagnosis is recommended.
