About E & S Construction Engineers Inc
The company holds contractor license #998235 in the California state contractor registry and has been licensed since 2014, which gives it more than 12 years of experience in the trade. That record matters when a project involves refrigerant handling, gas appliances, or changes to ductwork that affect an entire building.
The company's services include AC Services, Heating Services, Ductwork Services, Heat Pumps, Furnace Services, Thermostat Services, Emergency HVAC, and Maintenance & Tune-up. Typical work includes inspecting and cleaning coils, checking airflow and controls, sealing leaky ducts, installing and calibrating thermostats, and diagnosing urgent breakdowns. Scheduled tune-ups often catch small problems before they become expensive repairs.
California's climate is anything but uniform. Coastal fog, Central Valley heat, and mountain cold each place different demands on equipment, so local knowledge helps. Before choosing a pro, compare several local options, ask for written estimates, and confirm the license number yourself. HVAC Service Fast makes that comparison easier for anyone searching for a trusted HVAC contractor near them.

Local context for Hanover
Buying a new AC or heat pump in California
- California is in the DOE Southwest region: new central air conditioners installed since January 1, 2023 must meet at least 14.3 SEER2 and 11.7 EER2 (13.8 SEER2 and 11.2 EER2 for systems 45,000 BTU/h and larger). Heat pumps must meet 14.3 SEER2 and 7.5 HSPF2 nationwide.
- Since 2025, new systems are built for lower-impact refrigerants such as R-454B or R-32. Ask which refrigerant a quoted system uses and for its AHRI certificate number, which confirms the matched system’s rated efficiency.
