The answer to 'what does maintenance do' is that regular HVAC maintenance is essential for keeping your home's heating, ventilation, and air conditioning system running efficiently and effectively. Maintenance typically involves a thorough inspection, cleaning, and tuning of the various components in your HVAC system, such as the air filters, coils, and blower. This helps to improve indoor air quality, extend the lifespan of your equipment, and reduce energy costs by ensuring your system is operating at peak performance.
Regular maintenance also allows HVAC technicians to identify and address any minor issues before they turn into more serious and costly problems. By catching problems early, you can avoid unexpected breakdowns and the need for expensive repairs down the line.
