How do I choose a licensed, insured HVAC contractor in Ontario?

Ask for the contractor's state license number and verify it through the California contractor registry, then confirm they carry liability and workers' compensation insurance. Requesting written estimates from at least two companies also helps you compare pricing and scope.

What should I check before hiring an HVAC professional?

Confirm the license is active, ask for proof of insurance, and review written estimates that list parts, labor, and warranty terms. Ask whether the technician is trained on your specific equipment brand.

What are signs it is time to call an HVAC professional?
