We know Los Angeles neighborhoods the way only a local crew can. A compressor failure in Sherman Oaks on a 95-degree afternoon is a different job than a refrigerant leak in a West Adams bungalow. Same principles, different house, different system, different answer. That’s why we start every call with what’s actually wrong, not what’s easy to sell.

Why Dalton Heating & Air Is Los Angeles’s Preferred AC Repair Company

We’re a Garrison Partners company, held to The Garrison Standard since 2003. That means every repair comes with a written price before work starts, a written guarantee on the repair itself, and a free return visit if the fix doesn’t hold. Marco Benitez runs our Los Angeles operation, and he’s built the crew around one rule: show up inside the stated window and do the job by the book.

Homeowners in Los Angeles deal with a lot of HVAC companies that quote one price on the phone and a different one at the door. We don’t play that game. The price goes in writing first, on every job, without exception. You’ll know the exact number before a single panel comes off your unit.

Our technicians are background-checked and uniformed. You know who’s coming before they arrive. And when you call Dalton Heating & Air, a live person answers – 24 hours a day, 7 days a week. No voicemail queue, no callback window.

AC Not Blowing Cold Air in Los Angeles

AC not blowing cold air is the most common call we get in Los Angeles, and the cause is usually one of three things: a failed capacitor, low refrigerant from a slow leak, or a condenser coil so packed with dust and debris that the system can’t reject heat. Here’s what each one looks like and what it costs to fix.

Capacitor Failure And What It Means

The capacitor is the electrical component that gets your compressor and fan motor started. In Los Angeles’s dry season, dust builds up on electrical contacts and capacitors degrade faster than they do in cleaner air. A bulged or leaking capacitor usually means the outdoor unit hums but won’t start, or it starts and then trips the breaker. Replacing one typically runs $175 – $400 depending on the unit.

Refrigerant Leaks And Recharges

A refrigerant recharge – topping off the cooling fluid your system needs to hit set temperature – only makes sense if the leak is found and sealed first. Refrigerant doesn’t get used up; it leaks. In Los Angeles’s older housing stock, we regularly find slow leaks at the evaporator coil that previous companies just topped off and walked away from. Sealing the leak and recharging properly runs $300 – $765 depending on how much refrigerant the system needs and where the leak is.

AC Maintenance in Los Angeles

AC maintenance in Los Angeles is the cheapest insurance you’ll buy for your system, at $95 – $235 for a full tune-up. Given how much dust, palm debris, and dry-season grit our air carries, a system that skips maintenance for two or three years is usually running at 60 – 70% of its rated capacity. That means higher bills and a shorter life for the compressor.

What a Tune-Up Actually Includes

We don’t just change a filter and call it maintenance. A Dalton tune-up includes testing the capacitor, checking refrigerant charge against the manufacturer’s spec, measuring static pressure, cleaning the condenser coil, and verifying the thermostat is calibrated correctly. You get a written report of what we found and what it means, in plain language. Our technicians are not paid on what they sell, so the report is honest.

When to Schedule It

The best time for AC maintenance in Los Angeles is late spring, before the first real heat wave hits. That’s when systems that sat idle all winter are most likely to fail on startup. If you’re in the Valley – Sherman Oaks, Van Nuys, Encino – you’ll want to schedule earlier than coastal neighborhoods, since your system starts working hard sooner each year.

Trusted Brands We Service in Los Angeles

Our technicians are factory-trained to service nine major HVAC brands, including Los Angeles Trane service, and we stock common parts for Rheem, York, Daikin, and Bryant systems at our Los Angeles shop. That means less waiting on parts and faster turnaround when your AC goes down in July. Whether you’ve got a 2005 Carrier condenser in Sherman Oaks or a newer Daikin mini-split in a Silver Lake condo, we’ve worked on it before.

Common AC Repair Problems We See in Los Angeles Homes

• Oversized systems that short-cycle. Much of Los Angeles’s housing stock sits in mild coastal and basin microclimates, so many AC systems here run fewer hours per year than inland metros. An oversized system cools the house too fast, never pulls enough humidity, and the compressor dies young from constant cycling. Rule-of-thumb sizing instead of a real load calculation is the culprit.
• Condenser coils choked with dust and palm debris. LA’s dry season kicks up fine dust that settles into the coil fins, spiking head pressure and killing cooling capacity on hot afternoons. In neighborhoods with mature palm trees – think Mid-Wilshire or Hancock Park – that fibrous debris cakes onto coils faster than most homeowners realize.
• Capacitors dismissed as “just needs a recharge.” A weak capacitor is often misdiagnosed as a refrigerant issue by less thorough techs. We test the capacitor under load before recommending anything else. In Los Angeles’s heat, a marginal capacitor will fail completely within weeks.
• Evaporator coil leaks on older systems. Homes built before 1990 in Los Angeles often still run R-22 systems, and those coils are reaching the end of their service life. A leaking evaporator coil isn’t a recharge problem – it’s a replacement decision, and we’ll walk you through the honest math on repair versus replace.

The Load Calculation Question Most Los Angeles Homes Never Got

Here’s the thing most Los Angeles homeowners never hear: a proper load calculation changes what you should buy, and it changes what you pay to run it. In Sherman Oaks, we recently looked at a 2005 Carrier condenser that was tripping its breaker every afternoon. Our tech found a bulged run capacitor and a condenser coil packed with five years of valley dust. He tested the cap, replaced it, washed the coil, and verified refrigerant charge and static pressure before calling it fixed. The homeowner had been quoted a full system replacement by another company. At 12 tons of measured capacity need versus the 4-ton unit actually installed, the honest answer was a $340 repair, not an $8,000 install.

That’s the difference a real load calculation makes. Most AC systems in Los Angeles were sold on square-footage rules of thumb, not measured heat-gain calculations. An oversized system short-cycles, leaves rooms clammy, and burns out compressors early. If you’re being quoted a replacement, ask whether the contractor ran a Manual J load calculation. If they didn’t, get a second opinion.

What SEER2 Means on a Los Angeles Utility Bill

SEER2 is the updated efficiency rating for AC systems, and it matters more in Los Angeles than most homeowners realize. A system rated at 16 SEER2 versus 14 SEER2 will use roughly 12% less electricity to produce the same cooling. On a typical Los Angeles summer bill for a 1,800-square-foot home, that can mean $15 – $30 a month during peak season. Over a 15-year system life, that’s real money. But it’s only worth paying more for efficiency if the system is sized correctly. A high-SEER2 unit that’s oversized still short-cycles and still dies young.
