HVAC Retrofit Engineering in Menifee, CA

Menifee is a rapidly expanding Inland Empire community with significant residential development, light manufacturing, and distribution facilities supporting the San Jacinto Valley's growing logistics corridor.

What we engineer

Heat-pump and VRF/VRV conversions replacing gas and aging electric systems; dedicated outdoor air systems (DOAS) with energy recovery for humidity control; chiller and boiler plant retrofits; pneumatic-to-DDC controls upgrades; and refrigerant transitions off high-GWP HFCs per the AIM Act phasedown — full mechanical design with load calculations per ACCA Manual N / ASHRAE, ventilation per ASHRAE 62.1, and energy compliance per ASHRAE 90.1 and IECC.

Compliance & incentive stacking

NYC Local Law 97, Boston BERDO, Denver Energize Denver, Washington's Clean Buildings Performance Standard, Maryland BEPS, St. Louis BEPS — we engineer the HVAC retrofits that hit building performance standard targets, and we stack utility rebates (ComEd, Xcel, Mass Save, NYS Clean Heat, Energy Trust of Oregon, Efficiency Maine, Focus on Energy) to cut net project cost.
