HVAC — Commercial & Residential
Rooftop package units, retail preventative maintenance, and Title-24 compliant climate systems.
The Tri-Valley's premier suburb — upscale residential remodels, corporate office improvements, and retail maintenance programs.
JMG services and installs commercial HVAC for retail portfolios — the same rapid-response discipline trusted by national brands like Starbucks — with after-hours crews that never disrupt business hours.
In Pleasanton and across Alameda County, JMG delivers hvac under California Contractor's License #1007864 — permitted, inspected, and personally overseen by owner Jerry Guinn. For residential clients, we design high-efficiency heat-pump systems, zoning, and smart controls that keep luxury homes silent, comfortable, and energy-compliant.
Pleasanton's neighborhoods — from Vintage Hills to Ruby Hill — come with HOAs and design guidelines we satisfy before demo day. Vineyard-corridor estates, family-kitchen remodels, and retail work along Stoneridge and downtown Main Street all run through the city's permit center, which we manage end to end.
