Two systems replaced
Two complete systems replaced in Chino Hills. Both installed, commissioned and running normally.
Diagnostic
AC installed 2 years ago — after a new electrical panel, the tenant said no cooling. The electrician blamed the AC. We pulled out thermal imaging and found the real issue immediately. No guessing, no assumptions.
Ventilation
2,400 sq ft home with a poorly designed 5-zone duct system — every zone was uncomfortable and couldn't cool down even after running all day. We redesigned the ductwork and installed a new AC system. The homeowner felt the difference immediately.
