02Building types we design for
Seven sectors.
All under one roof.
We design HVAC for seven building types: office space, warehouses, mixed-use, senior assisted living, multi-family, retail and places of worship. From rooftop units on a retail center to a multi-zone VRF system for senior living, we've engineered and installed HVAC across every major commercial and multi-family building type. Our overview of the four commercial HVAC system types compares how each works and where it fits. Offices that fight over one thermostat get commercial zoning.

05Repair & maintenance
Commercial HVAC repair
and maintenance.
We repair and maintain the rooftop units and split systems already running on Sacramento-area commercial buildings, including equipment another contractor installed. Not every call is a new build.
Repair
Rooftop package units and split systems up to 25 tons, diagnosed on site and quoted before any work starts. One job from our records: a refrigerant circuit repair on an existing 7.5-ton Trane split system serving a Sacramento business.
When a unit is past repair, the same crew plans the replacement: we recently replaced a rooftop unit on a Sacramento building and added a supply grille to the plenum while it was open. Our guide to when a rooftop unit should be replaced covers the signs and what replacement day involves.
Planned maintenance
Visits on a fixed calendar set to the building, not a template. A Folsom business has had us on three visits a year since 2023, and we changed the rooftop unit filters for a Sacramento business on a recurring schedule for years. Each visit covers:
- Filters replaced, coils inspected and cleaned
- Refrigerant pressures and service valves checked
- Capacitors, contactors and compressor electrical tested
- Blower motor, bearings and fan blades inspected
- Thermostat and safety controls verified
06Service approach
We reasonably replace.
We do not upsell.
We replace only when it is reasonable and never upsell: diagnostics are flat-fee, the repair cost is quoted before we start, and if we can't identify the issue, there's no charge. If you decide not to proceed, a flat $89 diagnostic fee applies. Forthright pricing, never a surprise. For replacement budgets, our commercial HVAC replacement cost guide shows what real Sacramento jobs invoiced and what drives the number.
Upgrading equipment? SMUD offers energy-efficiency and electrification incentives for Sacramento businesses, including HVAC and heat pump upgrades through its Business Solutions and Rebates programs. We'll flag what your project may qualify for and build it into the bid. Our 2026 guide to SMUD commercial and multifamily HVAC rebates lists the per-ton amounts and the application steps.
