A home inspector notes whether or not the unit functions at all, but doesn’t conduct any in-depth tests. Service Champions, a Northern California HVAC company, explains:
Home buyers assume that the home inspector has tested their heating and air conditioning equipment. But the home inspector may simply turn on your furnace and air conditioner to make sure they work…. HVAC systems, like cars,
can work even if there are major problems.
By contrast, preventative maintenance is performed by a licensed HVAC contractor and is geared towards increasing the lifespan and performance of your unit. During maintenance, contractors not only inspect
the unit but also clean filters and coils and make any adjustments necessary. Learn more about preventative maintenance and its benefits here
