Top-rated independent heating and cooling across California's Central Valley and the Sierra foothills
Zoning Controls
We install and repair zoning controls, the dampers, zone panels and multiple thermostats that let one HVAC system hold different temperatures in different parts of a house. Homeowners across California and Nevada call us when upstairs runs ten degrees hotter than downstairs, when a back bedroom never cools, or when a zone damper has stuck and one area gets nothing. Call us with a rough description of which rooms misbehave and at what time of day, and we will look at the ductwork and controls together.

What a zoning control job involves
Zoning splits your duct system into separate areas, each with its own thermostat and a motorized damper in the branch duct. A zone panel wires it all together and tells the equipment when to run and how hard. On an existing system we usually add dampers in the attic or crawlspace, run thermostat wire to each zone, and mount the panel near the air handler. On a system already zoned, the work is often one failed damper motor, a dead thermostat, or a panel that lost its settings.
What we check and install
We start by measuring what the ducts can actually carry, because zoning a system that is already short on airflow just moves the problem around. We check static pressure, return sizing, damper positions, thermostat wiring and whether the equipment can run at reduced airflow without freezing the coil or short cycling. Then we install dampers sized to each branch, wire the zone panel, set up a thermostat per zone, and confirm each one opens and closes the right damper under real load.
How we decide it is the right call
Zoning makes sense when rooms are genuinely different loads, like a second floor under a hot attic or a west-facing addition, and the duct system has enough capacity to be split. If the real problem is a crushed flex duct, missing return air, or leaking duct in the attic, we say so and fix that first because it is cheaper and works better. We also talk through how many zones you actually need. Two well-planned zones usually beat four cramped ones.

Can zoning be added to my existing AC and furnace?
Often yes, if the ductwork has separate branches we can reach and enough airflow capacity. We inspect the duct layout and equipment first, since some single-speed systems need a bypass or control changes to run safely with zones closed.
Why does one zone stay warm even when its thermostat is calling?
Usually a stuck or failed damper motor, a broken thermostat wire, or a zone panel that lost its configuration. Sometimes the branch duct is simply too small for that area. We test the damper and wiring to tell those apart.
How many thermostats will I have?
One per zone, plus the zone panel that coordinates them. Two-story homes commonly run two. Larger single-story layouts with a hot wing might also use two. More zones means more dampers, wiring and control points to maintain.
How it works
- Step 1
Tell us the symptom
Call or fill in the quote form. We ask what changed, when it started, and what the thermostat reads. That tells us whether to bring parts for a cooling fault or a heating fault.
- Step 2
We diagnose on site
A technician checks the thermostat, the electrical side, airflow through the filter and coil, refrigerant pressures, and the outdoor unit. You get told what failed and why, in plain words, before anything is replaced.
- Step 3
Repair and verify
We make the repair, then run the system and measure the results at the vents. If a part needs ordering, we say so and give you a realistic window instead of a vague promise.

Why homeowners call us
- Built for real valley heatWe work in areas where afternoons sit above 110 degrees and systems run for months without a break. That shapes how we size repairs, check capacitors and contactors, and judge whether a compressor is genuinely done.
- Attic and package unitsPlenty of homes across the region run attic air handlers or rooftop package units instead of a garage furnace and a side-yard condenser. We are used to the access, the duct runs, and the drain issues those setups bring.
- Dust and debris we expectAg dust, cottonwood fluff and grass clippings pack condenser coils and starve a system of airflow. We clean what we find and show you the difference, rather than adding refrigerant to a unit that just could not breathe.
- Heating too, not only ACFurnace repair, heat pump faults and no-heat calls get the same attention as summer work. Ignition problems, cracked or failing components and short cycling all get diagnosed before we recommend anything larger.
