The answer to 'what is tune-up' is a routine maintenance service for HVAC systems. An HVAC tune-up involves a comprehensive inspection, cleaning, and adjustment of all the components in your heating and cooling system to ensure it is running efficiently and safely. This typically includes checking and replacing air filters, lubricating moving parts, testing electrical connections, and calibrating the thermostat.
Regular tune-ups are recommended once or twice a year, typically in the spring and fall, to prepare your HVAC system for the upcoming season. Tune-ups help extend the lifespan of your equipment, improve indoor air quality, and reduce your energy bills by optimizing system performance.
