How often should I schedule HVAC maintenance?
Heating and Air-Conditioning Equipment manufacturers universally recommend biannual preventive HVAC maintenance. It is suggested that one maintenance visit is performed prior to the Heating Season and another prior to the Air-Conditioning Season. Most equipment manufacturers require these regular check-ups to maintain the warranties on compressors and heaters for the duration of the warranty period.
