True Expertise for Your Commercial Heating & Cooling
Commercial systems aren't just larger residential units—they require specialized training, heavy-duty load management, and a deep understanding of complex zoning. If your AC goes down during a July heatwave, you risk losing inventory, driving away customers, and grinding employee productivity to a halt.
When you invest in commercial HVAC in Fresno, you need true experts who understand those high stakes. Our commercial technicians accurately diagnose complex issues and design heavy-duty systems built specifically to handle the brutal Central Valley heat, keeping your operations running smoothly.
The Grandmark Advantage: Fully Integrated Roof & HVAC Systems
Most commercial heating and cooling units sit directly on top of your building. This creates a massive headache for property managers: when a leak appears around the unit, the roofer blames the AC guy, and the AC guy blames the roofer.
You never have to deal with that finger-pointing again.
Because we are dual-licensed experts in both trades, we provide a fully integrated approach. When we install, repair, or service your rooftop packaged units, we guarantee the structural integrity of the roof beneath it remains flawless. We protect the entire envelope of your building from the inside out.
Comprehensive Recurring Services (HVAC + Roof Maintenance)
The secret to avoiding massive capital expenditures is keeping your equipment running efficiently for as long as possible. We offer customized recurring service agreements designed to protect your bottom line.
But our maintenance plans go a massive step further than standard commercial HVAC in Fresno. Our recurring services include both HVAC and roofing maintenance in a single visit:
-
Coils & Filters: Inspecting and cleaning your HVAC components for maximum airflow.
-
Electrical Testing: Testing electrical draws to catch failing parts before a catastrophic breakdown.
-
Membrane & Flashing Checks: Inspecting the roof seals around your HVAC curbs to prevent water intrusion.
-
Drain Clearance: Clearing debris from your rooftop drains to ensure proper water flow year-round.
One call. One trusted company. Total peace of mind for your property.
Upgrade Your Equipment With PG&E On-Bill Financing
Replacing an aging, inefficient system is a major investment, but it doesn't have to drain your operating capital.
We proudly help our commercial clients utilize PG&E On-Bill Financing (OBF). This program allows eligible businesses to upgrade their equipment with absolutely zero out-of-pocket costs.
-
0% Interest: Finance your new, energy-efficient equipment with zero interest.
-
No Upfront Capital: Keep your cash flow intact for your business operations.
-
Pay Through Your Utility Bill: Your repayment is added directly to your monthly PG&E bill, often offset by the massive energy savings generated by your new system.
