AC Repair in Calabasas, CA, for Hot Summers and Fire-Season Ash
“Installed the new AC quickly same day when mine broke on the hot summer day what a lifesaver!”
David Dorfman, ⭐⭐⭐⭐⭐ Google Review
What Calabasas Summers Do to an Air Conditioner
- Hot, dry afternoons. Average highs in Calabasas run 92°F in July and 93°F in August, and the record is 114°F. Next door in Woodland Hills it reached 121°F on September 6, 2020, the highest reading ever recorded in Los Angeles County. A compressor that runs from late morning into the evening is hardest on the run capacitor and the condenser fan motor, so those parts tend to quit late in the season.
- Attics and rooftops. The city publishes separate permit handouts for furnaces in attics and for rooftop units, which tells you where a lot of Calabasas equipment sits. Both spots run far hotter than the outdoor reading on a 95°F day, and the condensate drain from an attic unit is easy to forget until it clogs and water shows up on a ceiling.
- Wind, dust and ash. Calabasas sits in the foothills of the Santa Monica and Santa Susana mountains. Santa Ana winds push hot, dry air across those hills along with leaves, grit and, in fire season, ash. A packed outdoor coil can’t release heat, so pressures rise, the compressor runs hotter, and the system trips or starts blowing warm air.
Fire Season Leaves Ash in Your Calabasas AC
Calabasas knows fire season firsthand. The Woolsey Fire started on November 8, 2018, crossed the 101 near Calabasas overnight, and went on to burn 96,949 acres and destroy 1,643 structures. On the evening of November 11 the entire city was placed under a mandatory evacuation order. Then on January 9, 2025, the Kenneth Fire broke out near Valley Circle Boulevard, grew to 1,052 acres in Santa Ana winds, and forced evacuations that included Calabasas.
Ash doesn’t stop at the fire line. It drifts for miles, settles on outdoor coils and gets pulled into return filters. An AC that cooled fine before the smoke can start struggling in the days after it clears.
When the smoke clears, start here
- Change the air filter as soon as the air is clear. A filter loaded with ash chokes airflow, and low airflow can freeze the indoor coil.
- Shut the power off at the outdoor disconnect, then rinse loose ash off the outdoor coil with a garden hose on a gentle spray. Skip the pressure washer. It bends the fins.
- If the system still blows warm air, cycles on and off or trips the breaker, call us. We clean the coil and check pressures and the electrical parts, which tells us whether you need a cleaning or a repair.
Larger homes with more than one system
More than half of the homes in Calabasas were built in the 1980s and 1990s, and about two-thirds are detached single-family houses. Many are large. When the city reviewed homes for sale in June 2020, nearly half of the single-family listings had five or more bedrooms. A house that big often cools with two or more systems, and the city’s own HVAC permit worksheet asks how many a property has. When you call, tell us which part of the house is warm so we know which system to start on.
- Water on the ceiling under an attic unit usually means a clogged condensate drain and an overflowing pan. Turn that system off at the thermostat and call us. Drain line cleaning runs $265 – $395, and an overflow safety switch, which shuts the AC off before water reaches the ceiling, is $285.
- One warm wing or floor in a home with two systems usually means one system is down while the other keeps running. Check that zone’s thermostat and filter first, then have us check the refrigerant charge and the indoor coil on the system that serves it.
AC Repair Prices, Up Front
These are our own prices for the repairs we do most often, not industry averages. Every repair starts with a diagnostic, and it’s a $0 diagnostic fee when you approve the repair.
| Repair | Our price |
|---|---|
| Condenser fan motor | $695 – $895 (standard motors; variable-speed priced separately) |
| Condensate drain line cleaning | $265 – $395 |
| Condensate overflow safety switch | $285 |
| Compressor | $3,200 – $4,800 |
You hear the price for your repair after the diagnosis and before any work begins.
Southern California Edison delivers the power in Calabasas and sends the bill. The electricity itself comes from Clean Power Alliance, and the city’s default plan has been 100% Green Power since October 1, 2021. Either way you pay for every hour the AC runs. A system with a dirty coil, a weak capacitor or a low charge runs longer to do the same job, and that shows up on your Edison bill before the system quits.
When a replacement is the better buy
A compressor repair costs roughly a third of a complete heat pump replacement, which runs $11,200 – $15,000 for a 2.5-ton system with a matched air handler. On an older system, compare both numbers before you spend. If another company has already quoted you a replacement, we’ll give you a free second opinion.
A replacement in Calabasas needs a mechanical permit from the City of Calabasas Building and Safety Division, not from the county or LADBS. We pull the permit and schedule the inspection. Your written replacement quote includes the permit, Title 24 / HERS testing, and removal and haul-away of the old equipment. Estimates are free with no obligation.

Calabasas AC Repair Questions
In Calabasas heat the usual causes are a failed capacitor, a dead condenser fan motor, an outdoor coil packed with dust or ash, or a low refrigerant charge. Check the filter and make sure the outdoor fan is spinning. If the fan is still or the air stays warm, turn the system off and call us. Running it that way can take out the compressor.
Ash rarely breaks a part on its own. It clogs the filter and coats the outdoor coil, and the system then runs hot and long until something else gives out. After a smoke event, change the filter and rinse the outdoor coil gently. If cooling doesn’t come back, we clean the coil and check the system.
Every repair starts with a diagnostic, and it’s a $0 diagnostic fee when you approve the repair, because the fee is credited toward the work. You hear the repair price after the diagnosis and before any work begins.
Repairs such as a capacitor, fan motor or drain cleaning generally don’t need a permit. Replacing the equipment does. In Calabasas that’s a mechanical permit from the city’s Building and Safety Division. When we replace a system, we pull the permit and schedule the inspection.
Start with the one that’s failing. We diagnose that system and give you the price before any work begins. If the second system is the same age, it has been through the same summers and the same ash, so it’s worth a look before the next heat wave. Our maintenance plans put both systems on a regular schedule.
Repair it when the fix is small and the system has been dependable. Think about replacing when the compressor has failed, the system runs on R-22 and leaks, or you’ve paid for repairs several summers in a row. We give you the repair price and a free replacement estimate so you can compare. See AC installation in Calabasas.
