The answer to 'what does tune-up do' is a routine HVAC maintenance service that helps ensure your heating and cooling system is operating efficiently and safely. During a tune-up, an HVAC technician will inspect, clean, and adjust various components of your system to improve its performance and extend its lifespan.
Some of the key tasks performed during an HVAC tune-up include checking and cleaning the air filters, inspecting the thermostat, lubricating moving parts, checking refrigerant levels, testing electrical connections, and clearing any debris or buildup. This helps your system run more smoothly, use less energy, and avoid costly breakdowns down the line.
