Frequently Asked Questions
Always "auto" in humid climates. Running the fan continuously re-introduces moisture into the living space from the wet evaporator coil. "Auto" lets moisture drain properly and keeps indoor humidity lower.
Oversized AC units cycle off before they remove enough humidity. Ask a repair tech about a variable-speed blower or a dedicated dehumidifier — it is the single biggest comfort upgrade in humid climates.
Common HVAC repairs range from $150 to $750. A diagnostic service call is usually $75–$150. Replacing a capacitor runs $150–$350, a blower motor $350–$700, and a compressor $1,200–$2,500. Refrigerant recharge costs $200–$600 depending on the type. Full system replacement (furnace and AC) averages $7,000–$15,000 depending on system size and efficiency rating.
You should have your HVAC system professionally serviced twice a year: once in spring for air conditioning and once in fall for heating. Annual maintenance includes cleaning coils, checking refrigerant levels, inspecting electrical connections, lubricating moving parts, and testing system performance. Regular maintenance can improve efficiency by 15–25% and extend system life by 5–10 years.
Consider replacement if your system is more than 15 years old, requires frequent repairs (more than twice per year), uses R-22 refrigerant (phased out), or your energy bills are steadily increasing despite maintenance. A good rule of thumb is the $5,000 rule: multiply the age of the system by the repair cost, and if it exceeds $5,000, replacement is usually the better investment.
Common causes include a dirty air filter restricting airflow, low refrigerant from a leak, a frozen evaporator coil, a failing compressor, or a malfunctioning thermostat. Start by checking and replacing your air filter and ensuring all vents are open and unobstructed. If the problem persists, call a technician as refrigerant leaks and compressor issues require professional diagnosis and repair.
