It is recommended to service your HVAC system at least once a year. For best performance, schedule maintenance twice a year—before summer and before winter.

Common signs include unusual noises, weak airflow, uneven temperatures, foul smells, higher electricity bills, and the system taking longer to heat or cool.

A standard HVAC installation typically takes 4–8 hours. Larger or more complex systems may take up to 1–2 days depending on ductwork requirements.

Use a programmable thermostat, clean or replace filters regularly, schedule routine maintenance, ensure proper insulation, and upgrade to energy-efficient units.

If your system is over 10–12 years old, requires frequent repairs, or has poor efficiency, replacing it is often more cost-effective and energy-efficient.
