AC Tune-up in Highland, CA
- Coil cleaning, not just a filter swap
- Capacitor tested before it strands you in July
- Photos and readings sent with your report
- Booked around your schedule, 7 days a week
Catch the Small Stuff Before a 105 Degree Afternoon Finds It
We Take Readings, Not Guesses
Suction and liquid pressures, superheat, subcooling, amp draw, and temperature split. Those numbers show a system sliding out of spec months before it quits.
A Real Checklist, Every Visit
Twenty plus checks that get written down. You get the report with the actual values, not a green checkmark on a tablet nobody explains.
Cheap Fix Now Beats Emergency Later
A weak capacitor is a small part on a scheduled visit. The same part on a Sunday in August with a hot house is a very different day.
We Remind You Next Spring
One reminder, no nagging. Annual service also keeps most manufacturer warranties valid, which matters if a compressor ever fails.
What People Say After the Truck Leaves
"The tech found a capacitor reading way under spec and showed me the meter. Replaced it right then for a fair price. Best hundred dollars I have spent on this house."
"He spent almost an hour on it. Washed the coil, cleared the drain, checked the pressures, and sent me a report with numbers. Previous company was in and out in fifteen minutes."
"Our upstairs never cooled well. During the tune-up they found the return was choked with dust and a damper half closed. Big difference for a maintenance visit."

Spring slots fill fast once temperatures hit triple digits. One visit, flat rate, and a written report with your system readings.
What a Real AC Tune-up Covers
A tune-up should not be a filter change and a handshake. Out here the two things that kill air conditioners are heat and grit, and both build up quietly. A coil that looks fine from the patio can be packed solid an inch in, and the only sign is a system that runs longer every week until one afternoon it cannot keep up at all. The visit exists to catch that while it is still cheap.
We block out enough time to do it properly, usually around an hour for a single system. Here is what gets done on a residential visit:
- Wash the condenser coil and clear the fins, since dust off the wash and wind out of the canyons loads them faster than most homeowners expect.
- Test the run capacitor against its rated microfarads and check the contactor for pitted or welded points.
- Read refrigerant pressures against outdoor temperature, then calculate superheat and subcooling to confirm the charge is actually right.
- Clear the condensate drain and test the float switch, because a backed up line is what puts a stain on a ceiling in August.
- Check filter, blower wheel, and return airflow, then measure temperature split at the supply and return.
- Meter amp draw on the compressor and fan motor, tighten electrical connections, and inspect the disconnect and whip.
Timing and what we notice locally
The best time for cooling maintenance around here is March through May. Book it then and a weak part gets replaced on a mild day instead of during the first 100 degree stretch. We service a lot of homes up near Crafton Hills and along the Base Line corridor, and those areas take a heavy dust load off the open ground and the wind. A coil cleaning there does more for cooling capacity than anything else we could do in an hour.
The other pattern we see is short cycling in homes with newer oversized systems. The unit blasts, satisfies the thermostat in eight minutes, shuts off, and never runs long enough to pull humidity or even out the temperature between rooms. That is not something a part fixes, but catching it during maintenance means we can talk about airflow, dampers, and thermostat placement before you spend money on the wrong solution.
How the visit runs
- 1
Baseline Before We Touch Anything
The tech records starting pressures, temperature split, and amp draw so we can prove the visit actually improved something.
- 2
Clean the Outdoor Unit
Power off at the disconnect, cabinet opened, coil washed from the inside out, and debris pulled from the base. Landscaping gets moved and put back.
- 3
Test the Electrical Parts
Capacitor, contactor, wiring, and fuses all get checked cold. Anything reading out of spec gets shown to you with the meter on it.
- 4
Handle Airflow and Drainage
Filter, blower, evaporator access, and the condensate line. We flush the drain and confirm the float switch actually trips.
- 5
Recheck and Report
New readings after the cleaning, side by side with the baseline, plus photos of anything that needs watching next year.
What happens if we find a problem
If a part is failing, you get the reading, the price, and a yes or no decision. We do not bundle repairs into the tune-up price or start work without your approval. Small items like a capacitor or a contactor are usually done on the spot so you are not paying for a second trip.
If your system is old enough that maintenance is only buying time, we will say that too. Nobody here earns a bonus for pushing equipment, and a tune-up that quietly turns into a sales pitch is the fastest way to lose a customer. Honest maintenance is how Highland Heating & Air keeps the same homes on the schedule year after year.

AC Tune-up Questions, Answered
It is a flat $100 for a residential system, and that includes the coil cleaning, the full checklist, and the written report. Commercial equipment is quoted separately since rooftop units take longer and often need lift access.
Once a year, ideally in spring before the heat arrives. Systems here run far more hours than the same unit would in a coastal town, and the dust load along the Base Line corridor and out toward Mentone means coils foul faster than the manufacturer schedule assumes.
Plan on about an hour for one system. If we find something that needs cleaning out, like a blower wheel caked with dust, it can run longer. We would rather stay and finish than book too tight and rush.
A dirty condenser coil raises head pressure and makes the compressor work harder for the same cooling, so cleaning it usually shows up on the bill during summer. The bigger win is avoiding a $400 emergency on a Saturday in July.
Small parts like a capacitor or a contactor we can usually handle the same visit, and you approve the price first. Larger repairs get quoted in writing and scheduled. The tune-up fee never turns into a surprise line item.
If you have both cooling and heating, yes. The plan covers a spring cooling visit and a fall heating visit, gives you priority scheduling when the schedule is packed, and discounts the diagnostic if something does break between visits.
