HVAC systems should be serviced at least once a year. Cooling systems are best checked in the spring, and heating systems in the fall. Regular maintenance ensures efficiency, reduces the likelihood of breakdowns, and extends the life of your equipment.

With proper maintenance, HVAC systems typically last 15-20 years. However, factors such as the system’s quality, frequency of use, and the level of maintenance it receives can significantly impact its lifespan.

The right size depends on your home’s square footage, insulation, and climate. An undersized system won’t heat or cool efficiently, while an oversized one can waste energy. A professional load calculation is essential for accurate sizing.

Signs include unusual noises like banging or hissing, weak or inconsistent airflow, uneven temperatures, unpleasant odors, or a sudden spike in energy bills. Addressing these issues early can prevent more extensive and costly repairs.

Yes. Upgrading to a high-efficiency system reduces energy consumption, lowers utility bills, and often qualifies for rebates or incentives, making it a cost-effective investment over time.
