FAQ
Frequently Asked Questions
02
Do you offer same-day emergency commercial service?
Yes. We dispatch same-day across both counties for commercial emergencies — failed walk-ins, dead rooftops, leaking refrigeration, and no-cool calls during service hours. Call (909) 239-6364 Monday–Saturday 8AM–6PM.
03
Do you handle preventive maintenance for multi-site portfolios?
Yes. Our preventive maintenance plans cover portfolio-wide service with documented records, NTE budgets, and priority dispatch — designed for property managers, restaurant groups, and grocery operators that need predictable capex.
04
Do you work on both HVAC and refrigeration?
Yes — that's the point of a commercial partner. One crew handles your rooftop AC, walk-ins and reach-ins, kitchen exhaust hoods, and ice machines. Fewer vendors, faster response, one invoice.
05
Are you licensed, bonded, and insured?
Yes. Tech On Call is fully licensed, bonded, and insured for commercial HVAC and refrigeration work across California. Our techs carry EPA Section 608 Universal certification for refrigerant handling on every install, repair, and recovery.
06
