FAQ

When should you schedule HVAC maintenance?

Schedule maintenance twice yearly, before cooling and heating seasons begin. Spring and fall tune-ups catch refrigerant leaks, dirty coils, and worn capacitors before they cause breakdowns during peak demand. This timing prevents emergency repairs when systems work hardest.


What happens during an HVAC maintenance visit?

Technicians check refrigerant charge, clean condenser coils, test capacitors, inspect electrical connections, and verify thermostat calibration. Each component affects efficiency and lifespan differently. These checks catch most issues before they cause system failures.


How do you know when your HVAC system needs repair?

Weak airflow, temperature swings beyond three degrees of thermostat setting, frequent cycling, or unusual noises indicate problems. Ice on refrigerant lines or rising utility bills without usage changes also signal needed repairs before complete failure occurs


What affects HVAC repair costs?

System age, refrigerant type, component failure location, and replacement part availability all affect pricing. Compressor or evaporator coil replacement costs significantly more than capacitor or contactor repairs. Systems over twelve years old may warrant replacement instead of major repairs.


Should you repair or replace an aging HVAC system?

If repair costs exceed half the replacement cost and the system is over twelve years old, replacement usually makes financial sense. Frequent repairs, rising energy bills, and R-22 refrigerant systems all favor replacement over continued repairs.


Why does HVAC efficiency drop over time?

Refrigerant slowly leaks through microscopic seal failures, coils accumulate debris that blocks airflow, and capacitors weaken with heat cycles. Without maintenance, efficiency drops five percent annually as these issues compound and components degrade.


What causes uneven heating or cooling in different rooms?

Ductwork leaks, blocked vents, inadequate insulation, or improperly sized equipment create temperature imbalances. Single-zone systems struggle with multi-story homes or additions. Airflow testing identifies whether ductwork modifications or zoning systems solve the problem.


How does changing your air filter improve HVAC performance?

Clean filters allow proper airflow across evaporator coils, preventing ice buildup and compressor strain. Clogged filters force systems to run longer cycles to reach temperature, increasing energy use and shortening equipment lifespan through extended operating hours.


What's the difference between heat pump and furnace heating?

Heat pumps transfer heat from outdoor air indoors using refrigerant, while furnaces burn fuel to generate heat. Heat pumps cost less to operate in mild climates but lose efficiency below freezing. Furnaces provide consistent heat regardless of outdoor temperature.


When do HVAC systems need refrigerant added?

Refrigerant only needs adding when leaks occur-systems don't consume refrigerant during normal operation. Low refrigerant causes ice on lines, weak cooling, and compressor damage. Simply adding refrigerant without fixing leaks wastes money and harms the environment.
