The answer to 'how does tune-up work' is a routine maintenance service for your home's heating, ventilation, and air conditioning (HVAC) system. A tune-up involves a comprehensive inspection and cleaning of your HVAC equipment to ensure it's running efficiently and safely. This typically includes checking and adjusting components like the thermostat, air filters, refrigerant levels, electrical connections, and more.
A professional HVAC technician will perform the tune-up, which usually takes 1-2 hours. They'll inspect the entire system, clean and lubricate moving parts, and make any necessary adjustments or repairs. This helps your HVAC system operate at its best, extends its lifespan, and can even improve your home's indoor air quality.
