It’s recommended to have your HVAC system professionally maintained at least once a year. For air conditioners, maintenance is best in the spring before the summer heat hits. For heaters, schedule a maintenance check in the fall to ensure it's ready for winter. Regular maintenance helps avoid costly repairs and improves system efficiency.

If your HVAC system is over 10-15 years old and requires frequent repairs, replacement may be more cost-effective in the long run. Repairs are ideal for minor issues, but if the system is outdated or inefficient, replacement will ensure better energy savings and performance. A qualified technician can help you decide based on your system’s condition.

To improve energy efficiency, ensure that your HVAC system is well-maintained and replace filters regularly. Consider upgrading to a programmable thermostat, sealing leaks around ducts, and scheduling annual inspections. Additionally, investing in a more energy-efficient model can significantly lower utility costs.

Most HVAC systems come with a manufacturer’s warranty that covers specific repairs or parts. The warranty duration varies by brand and model, typically lasting from 5 to 10 years. Be sure to check your system’s warranty details, and if the system is under warranty, you may avoid repair costs by using a certified technician.
