Our AC Maintenance Services: What We Do Step by Step
Here is what an HVAC service technician works through from arrival to final test.
Step 1: Initial System Assessment
Before opening panels, we do a visual walkthrough of the indoor air handler and the outdoor condenser unit. We check for visible damage, unusual wear, and any signs of leakage or rust.
Step 2: Air Filter Inspection
We remove and inspect air filters. If it is clogged, we can replace it. For homes with multiple air handlers or ductless systems, we check the filter at every indoor unit.
Step 3: Evaporator and Condenser Coil Cleaning
We clean both the indoor evaporator and the outdoor condenser coils. We also inspect the condenser fins and straighten any that are bent.
Step 4: Condensate Drain Cleaning and Pan Inspection
The condensate drain removes moisture that the evaporator coil pulls from the air. Over time, algae, mold, and debris can build up inside the drain line. We flush it to clear any blockages and check the condensate pan for cracks, standing water, or algae growth.
Step 5: Refrigerant Level Checks
We check to ensure that the system is charged. If levels are low, we inspect lines and connections for leaks before adding more refrigerant.
Step 6: Electrical Components Inspection
We test the capacitor to rule out hard-start issues that can strain the compressor. We also inspect the contactor and all connections.
Step 7: Blower Motor and Fan Inspection
The blower motor moves air through your ductwork. We inspect motors, blowers, and condenser fans for damage.
Step 8: Ductwork Assessment
Poor ductwork is a common issue in older Altadena homes. We check duct connections at the air handler for leaks and measure static pressure to confirm airflow is normal.
Step 9: Thermostat Calibration
We calibrate the thermostat for accurate temperature readings and test all safety controls. We also service smart thermostats.
Step 10: Final Performance Test
We run the system in cooling mode to confirm it works as expected. A peak functioning system should produce a temperature split of 16 to 22 degrees Fahrenheit across the coil. We record the final readings and walk you through what we did. We also offer tips to prevent future issues.
Why Is Regular AC Maintenance Important in Altadena?
Altadena sits at the base of the San Gabriel Mountains. Here, summer temperatures reach the triple digits. So, AC systems can run for months. That load wears out capacitors, refrigerant lines, and coil surfaces. You slow wear and detect damage early through regular tune-ups.
Also, many Altadena homes were built between the 1940s and 1970s. The ductwork in these old homes often has unsealed joints and undersized returns that restrict airflow.
Finally, a neglected system does not fail all at once. It slowly degrades over time. But the resulting repairs are often more expensive than the annual visit that could have prevented them.
Hear From Dennis: An AC Service Call Case Study
Dennis called us when his AC kept shutting off after about an hour. Water was pooling in the secondary drip pan and hitting the emergency shut-off wire.
Jay, one of our technicians, came out and opened the condenser unit to assess. His first check was the condensate drain line. Even though Dennis had already cleaned part of the drain, Jay flushed the full line with nitrogen and found a blockage inside.
Then Jay noticed something Dennis had not seen. A metal splash guard inside the unit, designed to catch water blow-back from the air moving across the coil, had lifted slightly. Water was getting past the drip pan lip instead of draining into it. Jay used a spent CO2 canister to wedge the guard back down against the pan, sealing the gap.
After the visit, the secondary pan was completely dry. The AC ran smoothly, and the musty smell that came with the unit starting up was gone. Dennis noted the price was very reasonable and that he learned a lot while watching Jay work through the diagnosis.
This is what hands-on, honest AC maintenance looks like. No unnecessary parts replacements, clear explanations, and permanent fixes.
How Much Does AC Maintenance Cost?
A standard residential AC maintenance visit in the Altadena area costs between $75 and $200. The price changes based on the scope of service, system size, and number of indoor units.
A basic tune-up covers only a filter check, a visual inspection, and a refrigerant check. A comprehensive visit at the higher end covers every step, including coil cleaning, drain flushing, capacitor testing, and a full performance test.
If our technician finds a repair need during the visit, they will give you a clear, upfront estimate. You decide whether to proceed.

Frequently Asked Questions
Is Altadena a part of Pasadena?
No. Altadena is located directly north of Pasadena. It has its own area codes (91001 and 91003) and community character. But it is governed by the LA County Board of Supervisors rather than its own city council.
What town is close to Altadena?
Pasadena borders Altadena to the south. La Cañada Flintridge is to the west, and Arcadia and Monrovia are to the east.
How hot does Altadena get in summer?
Summer temperatures in Altadena regularly reach 95 to 100 degrees Fahrenheit. The foothill terrain can trap heat in neighborhoods during peak heat events. July and August are the hottest months.
How long does an AC maintenance visit take in Altadena?
A standard maintenance visit takes between one and two hours. If the system is larger, has multiple zones, or needs repairs, the visit may run longer.
Can I use my AC in Altadena without getting it serviced?
You can run it, but performance drops over time without maintenance. Skipping inspections does not eliminate problems. It delays them until they cost more to fix.
