AC Repair FAQs

Should I repair or replace my HVAC system?

Consider replacement if: your system is over 10-15 years old, repairs cost more than 50% of replacement cost, energy bills are rising significantly, you have frequent breakdowns, or your system uses R-22 refrigerant (being phased out). Repair if: the system is under 10 years old, the repair is minor, and efficiency is still good. A professional can help evaluate your specific situation.

What do SEER, AFUE, and HSPF ratings mean?

These ratings measure HVAC efficiency: SEER (Seasonal Energy Efficiency Ratio) rates air conditioners and heat pumps in cooling mode—higher is better, with 14+ being standard and 20+ being high-efficiency. AFUE (Annual Fuel Utilization Efficiency) measures furnace efficiency as a percentage—90%+ is high-efficiency. HSPF (Heating Seasonal Performance Factor) rates heat pump heating efficiency—8+ is good, 10+ is excellent.
