Top-rated independent heating and cooling across California's Central Valley and the Sierra foothills
Furnace Tune-Up
A furnace tune-up is a scheduled inspection and cleaning of your heating system before you lean on it, and we do them for homeowners across California and Nevada. Most people book one in early fall, after the furnace has sat idle through a long cooling season and the burners, blower and flue have collected dust. If your heat came on last winter with a burnt smell, short cycles or weak airflow, that is the signal. Call us and we will get you on the schedule before the first cold snap.

What a furnace tune-up actually involves
We start with the system running so we can see how it behaves, then shut it down and open it up. That means cleaning the burners, checking the ignition or pilot assembly, inspecting the heat exchanger for cracks or scorching, and pulling the blower wheel area clear of dust. We check gas pressure and temperature rise against what the unit is built for, tighten electrical connections, and confirm the flue is drawing properly. Filter gets changed. Then we run a full heating cycle and watch it complete.
What we check and what we replace
Safety controls come first. We test the limit switch, the flame sensor, the pressure switch and the rollout switch, because those are what stop a furnace from becoming a problem. Flame sensors get cleaned or swapped when they read weak. We look at the capacitor and blower motor amp draw, the thermostat calibration, and the condition of the ductwork near the cabinet. On attic and package units we also check the drain and the platform, since heat and cooling share that box in a lot of homes across the region.
How we decide a tune-up is the right call
If your furnace runs but you have not had eyes on it in over a year, a tune-up is the right visit. If it is not lighting at all, cycling off after a minute, or making a grinding noise, that is heating repair and we treat it that way. We will tell you which one you are looking at before we start. And if you ever smell gas, leave the house, call 911 or your gas utility from outside, then call us.

How often should a furnace be tuned up?
Once a year, ideally in fall before you need heat. Systems that share a cabinet with cooling equipment or sit in a hot attic collect more dust and benefit from that yearly look.
Can a tune-up turn into a repair?
Sometimes. If we find a cracked heat exchanger, a failed control or a motor drawing too much current, we stop, explain what we found, and give you the options before doing any work.
What can I check before we arrive?
Thermostat batteries and settings, the breaker for the furnace, your filter, and whether supply vents are open. That covers a fair share of no-heat calls and costs you nothing to look at.
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.
