Regular HVAC maintenance is crucial for several reasons. It helps ensure optimal system performance, energy efficiency, and indoor air quality. Maintenance also prevents potential breakdowns, extends the lifespan of the equipment, and maintains manufacturer warranties. HVAC technicians perform inspections, cleanings, and adjustments to keep systems running smoothly.

Air filters should typically be changed every 1 to 3 months, depending on factors such as the type of filter, the level of indoor air pollutants, and the system usage. HVAC technicians often recommend checking filters monthly and replacing then when they become dirty or clogged. Dirty filters restrict airflow, leading to reduced efficiency and potentially causing strain on the system.

The size of an HVAC system is determined by factors like the square footage of your home, insulation quality, local climate, and number of occupants. HVAC technicians use load calculations to determine the appropriate size for efficient heating and cooling. Oversized systems may short-cycle and waste energy, while undersized systems struggle to maintain comfort. A professional technician can provide accurate sizing recommendations.
