Frequently Asked Questions

Can staff change commercial HVAC filters?

Yes — filter changes are safe for trained staff on accessible units. For rooftop units without safe roof access, keep it on the PM contract.

How often should we clean condenser coils?

Once a year at minimum. Restaurants and businesses near freeways or landscaping should go twice a year — grease and pollen destroy coil efficiency.
