Mark Dattilo's heating and air conditoning

Mark Dattilo’s Heating and Air Conditioning is a local air conditioning contractor serving San Bernardino with repair, replacement, and preventive maintenance for residential and light commercial systems. For faster service, call to ask about same-day appointments, emergency availability, and whether they stock parts for your system’s brand. If you’re considering a new unit, request a written, itemized estimate, ask about energy-efficient options, manufacturer rebates, financing, and warranty coverage, and ensure a proper load calculation is included. To keep your system running smoothly, schedule a preseason tune-up and ask about an annual maintenance plan that includes coil cleaning, filter changes, and priority service.
