Top-rated independent heating and cooling across California's Central Valley and the Sierra foothills
HVAC Maintenance — Book a Visit Today
We service and tune up air conditioners, heat pumps and furnaces across California and Nevada, and the right time to book is before the season turns. Most breakdowns we see start small: a filter left in too long, a condenser packed with ag dust and cottonwood fluff, a weak capacitor, a drain line filling with sludge, a blower wheel caked enough to starve airflow. A maintenance visit means we check refrigerant performance, electrical connections and amp draw, clean the coils, clear the condensate path, test the ignition and safety controls on gas equipment, and measure temperature split at the vents. You get a plain list of what we found and what can wait. Call us or book online and we will schedule your AC tune-up or furnace tune-up.

The HVAC maintenance symptoms we hear most
- The AC runs all afternoon and never catches up Dirty coils, low airflow or refrigerant charge falling off
- There is water on the floor or ceiling under the unit Plugged condensate drain or rusted-out drain pan
- The system trips the breaker on hot days High amp draw from a failing capacitor, contactor or compressor
- The furnace lights, runs a minute, then shuts off Dirty flame sensor, blocked flue or a safety limit tripping on heat buildup
- The outdoor unit screeches or rattles when it starts Worn fan motor bearings, loose blade or debris inside the cabinet

How often should HVAC maintenance be done?
Twice a year suits most homes in California and Nevada: a cooling visit in spring and a heating visit in fall. If your system runs long hours through triple-digit summers or sits in a dusty area, we often suggest the cooling check earlier in the season.
What happens during an AC tune-up?
We measure temperature split and airflow, check refrigerant performance, wash the outdoor coil, test capacitors, contactors and amp draw, clear the condensate drain, and inspect the blower wheel and filter. Then we tell you what we found and what it means.
Is a furnace tune-up worth it if the heater seems fine?
Yes, because the parts that fail are the ones you cannot see. We check the heat exchanger, ignition, flame sensor, gas pressure and safety controls. Small heating repair issues caught in fall are far easier than a cold morning with no heat.
Will maintenance keep my system from breaking down?
It reduces the odds and catches wear early, but nothing prevents every failure. What maintenance reliably does is keep airflow and refrigerant performance where they belong, so the equipment is not fighting itself through the worst weeks of summer.
Do you offer seasonal maintenance visits on a schedule?
We do. Seasonal maintenance visits put you on a spring and fall rotation so we reach out instead of you remembering. It also means we already know your equipment, its age and its history when you call for air conditioning repair.
How long does a maintenance visit take?
Plan on about an hour to ninety minutes for a single system in good shape. Attic package units, rooftop equipment, heavy coil cleaning or a system we have not seen before can take longer. We will tell you if we need extra time.
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.
