HVAC — Commercial & Residential
Rooftop package units, retail preventative maintenance, and Title-24 compliant climate systems.
Estate contracting for hillside properties, vineyard-adjacent residences, and custom homes in the foothills of the Santa Cruz Mountains.
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 Saratoga and across Santa Clara 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.
Saratoga projects near the Village respect its historic character, while hillside homes fall under the city's hillside development standards — grading limits, view protection, and engineered drainage. From Saratoga Village storefront refreshes to hillside estate rebuilds, we coordinate the review boards so approvals never stall your build.
