Good To Know

Commercial maintenance FAQs

What clients ask before putting their plant on a program.

How often should commercial air conditioning be serviced?

Most commercial plant should be serviced quarterly, with filters checked more often in dusty or high-traffic sites. We build the schedule around your equipment, environment and compliance obligations rather than a one-size-fits-all calendar.

Do you provide service reports and compliance records?

Yes — every visit is documented with what was checked, what was found and what's recommended. You get an asset register and a paper trail your landlord, insurer or auditor will actually accept.

What about refrigerant leaks and compliance?

We're licensed to handle refrigerants, and leak checks are part of every maintenance visit. Catching a slow leak early protects your compressor — the most expensive part of the system — and keeps you compliant.

Can you take over maintenance from another contractor?

Easily. We start with a site audit and asset register so you know exactly what you have and what condition it's in, then propose a schedule and price. Most handovers are seamless within one visit.
