Can I perform HVAC maintenance myself or should I hire a professional?

You can change filters and clear outdoor debris yourself, but hire a professional for full HVAC maintenance. We recommend service twice a year before cooling and heating seasons. A pro inspects flues, tests burner ignition, checks electrical connections, cleans heat exchangers, lubricates parts, calibrates thermostats, and tests for carbon monoxide and gas leaks. Maintenance visits are documented online and help keep warranties in effect. Priority Service Plans add priority scheduling and up to 15% member discounts for HVAC in Arlington and Woodbridge.
