HVAC stands for Heating, Ventilation, and Air Conditioning. It’s a system that provides heating and cooling to residential and commercial buildings by controlling the indoor temperature and humidity. The system typically includes components like a furnace, air conditioner, ducts, and a thermostat, which work together to regulate temperature and airflow.

It’s recommended to service your HVAC system at least once a year, ideally in spring for cooling systems and fall for heating systems. Regular maintenance helps prevent breakdowns, improves efficiency, and extends the lifespan of your unit.

With proper maintenance, most HVAC systems last between 10-20 years. Regular servicing, timely repairs, and using high-quality components can help prolong its lifespan.

Signs include strange noises, weak airflow, inconsistent temperatures, higher energy bills, unpleasant odors, or the system frequently cycling on and off. Any of these symptoms can indicate a need for professional inspection and possible repair.

High-efficiency systems use less energy to achieve the same comfort levels, which can lead to significant savings on utility bills. They also reduce carbon footprint, improve indoor air quality, and often qualify for rebates and tax incentives.
