Top-rated independent heating and cooling across California's Central Valley and the Sierra foothills
Pre-Season Cooling Checks Worth Doing
Every year it happens the same way. March is mild, April is fine, then one week in May the temperature jumps thirty degrees and the AC that worked all last summer blows warm air. We get the calls in a wave. The fix is usually simple, and it is a lot easier to sort out in April than during the first triple-digit stretch.

What the first hot week actually does to your system
Your air conditioner sat unused for six or seven months, then gets asked to run twelve hours a day at outdoor temperatures well above what most equipment is rated to handle comfortably. Capacitors that were weak in October fail under that load. Refrigerant that leaked slowly all winter finally drops low enough to show up as warm air. Condenser coils packed with ag dust and cottonwood fluff cannot reject heat, so pressures climb and the compressor works harder than it should. Nothing about this is dramatic. It is just that heat exposes every marginal part at once, and the parts that were going to fail all fail in the same two weeks across the region.
Which failures spike, and when
Late spring is capacitor season. It is the single most common no-cooling call we run in the first hot stretch, and the symptom is usually a humming outdoor unit with a fan that will not spin. Low refrigerant shows up next, often as an AC that runs constantly and cools a few degrees at best. By mid-summer we shift to drainage problems and clogged condensate lines, blower motors, and contactors burned from cycling hard. Attic package units add their own list, since the unit lives in an oven and the ductwork up there loses cooling before it reaches the room. Thermostat and wiring faults turn up all season.
Checks you can safely do yourself
Start with the thermostat. Fresh batteries, set to cool, fan on auto, and a setpoint a few degrees below the current room temperature. Then check your breaker panel for anything tripped, including the outdoor disconnect breaker. Change the filter if you cannot remember the last time, and put it in with the arrow pointing toward the furnace or air handler. Walk the outside unit and clear weeds, leaves, and cottonwood from around it, giving it a couple of feet of open space on all sides. Last, open the supply vents and pull furniture off the returns. Stop there. Refrigerant, gas, and high voltage are ours to handle.
Signs worth a service call before June
Call us if the AC runs but the house never reaches the setpoint, if the outdoor unit hums without the fan turning, or if you hear a new grinding or screeching. Ice on the refrigerant lines, water stains near an indoor unit, or a breaker that trips more than once all point to something that will not survive a heat wave. If you smell gas at any time of year, leave the building first, then call 911 or your gas utility from outside, then call us. Same for a carbon monoxide alarm. Air conditioning repair booked in spring is a shorter wait than the same repair in July.
What a pre-season visit covers
We check the electrical side first, since that is where most early-summer failures start. Capacitor readings, contactor condition, wiring, and amp draw on the compressor and blower motor. We measure the temperature difference across the coil to see whether the system is actually moving heat the way it should. We wash the condenser coil, which in this region is usually the biggest single improvement, and clear the condensate drain. We look at the filter, the blower wheel, and the duct connections. If we find something on its way out, you hear about it then, with the option to fix it before the weather forces the issue.
Pre-Season Cooling Checks Worth Doing — straight answers
When should I have the AC checked?
Aim for March or April, before the first sustained hot week. Spring scheduling is easier, and any part we find failing can be replaced before you actually need the cooling every day.
My AC worked fine last September. Why would it fail now?
Sitting idle all winter is hard on capacitors and motors, and a slow refrigerant leak keeps leaking whether the system runs or not. Heat exposes weak parts that a mild day never stressed.
Is a maintenance visit worth it if nothing seems wrong?
Usually yes, mainly for coil cleaning and electrical readings. A condenser packed with dust and cottonwood runs hot all summer, and a weak capacitor gives measurable warning before it strands you.
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.
