Structured HVAC Maintenance Programs for Commercial Buildings
The most expensive HVAC problem is the one you didn’t prevent. Circulating Air’s maintenance programs give commercial facility managers what they actually need: predictable costs, fewer emergencies, longer equipment life, and a single contractor who knows your building inside and out.
We offer three tiers of ongoing support — from scheduled preventive maintenance to comprehensive service agreements to active energy optimization. Each program is built around your equipment, your budget, and your operational requirements.

Choose the Right Level of Protection
Preventive Maintenance
Scheduled inspections, cleaning, and tune-ups that catch problems before they become emergencies. Our NATE-certified technicians follow manufacturer-recommended protocols for every piece of equipment in your facility. Most commercial facilities see a measurable drop in emergency repair costs within the first year.
Service Agreements
Everything in preventive maintenance, plus priority dispatch, dedicated account management, and preferential pricing on repairs and parts. A service agreement formalizes the relationship — you get a contractor who knows your building, your equipment history, and your operational priorities.
Energy Optimization
Energy Audits
Most commercial buildings waste 15–30% of their HVAC energy spend. An energy audit identifies exactly where the waste is — and what to do about it. We perform ASHRAE-level facility assessments that deliver actionable findings, not just reports.
