Package Unit Systems
All-in-one rooftop & side-yard units — serving Concord and all of Contra Costa County.
Package Unit Systems in Concord & Contra Costa County
Package units put the heating and cooling equipment in a single cabinet outside the building — on the roof or beside the structure — which saves interior space and simplifies service. We install, replace and repair gas-electric and heat pump package systems, including curb adapters, transitions, and the duct connections that make or break their efficiency.
Every visit starts with a real diagnostic and ends with a written price you approve before the work begins. We answer the phone 24 hours a day and provide clear written pricing.
Every job covers the essentials
- Rooftop and ground-mount package unit installation
- Gas-electric and heat pump configurations
- Curb adapters and duct transition fabrication
- Full changeout of aged or failed units
- Economizer and control troubleshooting
- Preventive maintenance agreements available
Four steps from first call to final check
Site Evaluation
We check curb dimensions, structural support, gas, electrical, and duct connections.
Changeout Plan
Crane or lift needs, adapter fabrication, and downtime are scheduled up front.
Set & Connect
Unit set, sealed to the curb, and tied into gas, power, and duct with new transitions.
Startup & Test
Heating and cooling stages, safeties, and controls are all verified under load.
The difference a proper job makes
Diagnostics, sizing and installation quality decide whether a system runs quietly for fifteen years or becomes an annual repair bill.
Fixed the Same Day
We dispatch fast and carry the common failure parts, so most calls are resolved on the first visit rather than after a return trip.
Price Before the Work
You approve a written number before anything begins. No hourly meter, no add-ons discovered halfway through the job.
Measured, Not Guessed
Airflow, static pressure and refrigerant charge are all tested, so the fix addresses the real cause instead of the obvious symptom.
Built to Code
Every installation is completed to current California code and verified under load before we consider the job finished.
Detail-driven from start to finish
Reliable HVAC comes from disciplined habits, not shortcuts. This is the standard we hold ourselves to on every call.
Plain-English Answers
We explain what failed and why, without the jargon or the pressure.
Proper Load Sizing
Equipment is matched to your home, not to a rule of thumb or the last unit installed.
Quality Components
We install parts chosen for service life in a hot inland climate, not the cheapest available.
Respect for the Home
Floors covered, work area cleaned, and old equipment hauled away when we leave.
Verified Performance
Temperature split, airflow and safeties are all confirmed and documented before sign-off.
Current Promotions
Ask about current repair, installation, ductwork and military promotions when you schedule.
