Air Conditioning Engineering

Air Conditioning Engineering is an air conditioning contractor in Rancho Cucamonga that helps with AC repair, replacement, and seasonal maintenance. Before you commit, ask for a written, itemized estimate, a proper Manual J load calculation for replacements, and recommendations on SEER2/ENERGY STAR systems plus any local rebates or financing. If you need a repair, confirm the diagnostic fee, whether it’s applied to the job, expected same-day or next-day availability, and the parts-and-labor warranty in writing. For better comfort and efficiency, ask about ductless mini-splits or zoning, smart thermostat integration, and a maintenance plan that offers priority scheduling and tune-up discounts.
