Generally, HVAC service costs may include a combination of labor, materials, and any applicable fees.  It’s recommended to obtain quotes from multiple HVAC companies to compare prices and ensure you’re getting a fair deal.


What is included in an HVAC maintenance visit?
An HVAC maintenance visit typically includes a thorough inspection and servicing of your heating and cooling system to ensure it’s running efficiently and reliably. This may involve tasks such as cleaning or replacing air filters, lubricating moving parts, checking and adjusting thermostat settings, inspecting ductwork for leaks, testing system controls, and verifying refrigerant levels for proper cooling performance.
