HVAC — Commercial & Residential
Rooftop package units, retail preventative maintenance, and Title-24 compliant climate systems.
High-income residential remodeling minutes from Sand Hill Road — venture-capital discretion with builder-grade accountability.
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 Menlo Park and across San Mateo 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.
Menlo Park runs from Allied Arts and Sharon Heights estates to Belle Haven infill — with flood-zone considerations near the Bay and a building department that expects complete submittals. We deliver estate remodels, retail work along Santa Cruz Avenue and El Camino Real, and ADUs engineered to the city's standards.
