HVAC — Commercial & Residential
Rooftop package units, retail preventative maintenance, and Title-24 compliant climate systems.
The Capital Region's growth corridor — commercial development, metro residential remodels, and our northern anchor for statewide coverage.
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 Sacramento and across Sacramento 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.
Sacramento's older housing stock — the Fab Forties, Land Park, East Sac — rewards contractors who respect original details, while Central Valley heat makes HVAC and envelope work mission-critical. Permits run through the city's Community Development Department, and our retail crews cover the full corridor from the Bay Area to the Valley.
