What's Different After a Professional AC Installation
Why Inland Empire Homeowners Choose Us for AC Installation
Gardner Plumbing Co. is a licensed HVAC contractor serving Murrieta, Temecula, Menifee, and the greater Inland Empire (CA Contractor's License {{CSLB_C20_LICENSE_TBD}}). Our HVAC team has installed over 500 cooling systems across Riverside County — from single-zone replacements in Canyon Lake to full-home central air builds in new construction in Menifee.

Proper Sizing, First Time
Undersized systems never catch up in July heat. Oversized systems short-cycle and wear out early. We calculate the right tonnage before any equipment is ordered.
Licensed HVAC Technicians
Every technician carries a valid CA HVAC license and passes background verification. All installations meet Riverside County code requirements.
Upfront Installation Pricing
You receive a written quote with equipment and labor broken out before we order anything. The number on the quote matches the number on the invoice.
30+ Years Serving the IE
Three decades in Riverside County means we know local code requirements, utility rebate programs, and which systems hold up best in IE summer conditions.
