Ductwork Repair and Sealing in Burbank
Leaky attic ducts found, sealed and verified so the cold air reaches the rooms you paid to cool.
Inland Valley summers sit in the high 90s and push past 105 during a Santa Ana event, and the heat holds overnight so a system never gets its usual evening recovery.
What we see most in the Valley
The failures we see most are run capacitors cooked by attic heat, condenser coils packed with Santa Ana dust, and systems that were oversized on replacement and now short cycle.
Much of the Valley is 1950s and 1960s tract housing where the ductwork runs through an uninsulated attic that hits 140 degrees, so duct leakage costs more here than the condenser ever will.
How We Actually Diagnose It
A real diagnosis is a set of measurements, not a look and a guess. We put a manifold gauge set on the system and compare superheat and subcooling against the manufacturer's target for that model, because a system can be low on charge and still blow cold air for a while before it fails outright. We measure the temperature split across the evaporator coil, the delta-T, which sits near 16 to 22 degrees on a healthy system. We check static pressure across the air handler with a manometer, because a crushed return or a restricted filter imitates almost every refrigerant fault there is, and replacing a compressor on a duct problem is an expensive way to fix nothing. We test the run capacitor under load with a multimeter instead of judging it by sight, and we compare compressor amp draw against its rated load. When we open a sealed system for a repair we pull a vacuum down to 500 microns before recharging, because moisture left in a line set is what destroys the next compressor. If a reading is out of spec, we show it to you.
What Changed With Refrigerant
This changed recently and it affects what you can actually buy. Under the EPA's AIM Act rules, manufacturers stopped building R-410A residential equipment on 1 January 2025, and since 1 January 2026 a new R-410A system can no longer be installed at all. New equipment now uses an A2L refrigerant, usually R-454B or R-32, which carries a much lower global warming potential. A2L means mildly flammable, which sounds alarming and is not: the burn velocity is very low, and it changes how the equipment is built and handled rather than how it behaves in your house. None of this makes your existing system illegal. An R-410A system already in place is fine to keep and fine to service, but R-410A supply is tightening and the price per pound climbs every year, which is worth weighing if you are deciding between a large repair and a replacement. If your system is old enough to still run R-22, that one was phased out in 2020 and is genuinely scarce and expensive.
Your Building Climate Zone
For Title 24 purposes we work in California building climate zone 9. Burbank and Glendale are the reference cities for Zone 9, so the assumptions written into the code for a permitted changeout were built around this exact climate. Zones follow the state's reference weather stations rather than city limits, so if your address sits near a boundary the building department's written determination is the one that counts.

What Does AC Repair Cost in Burbank?
Ranges below are typical Los Angeles market figures reported by industry cost guides in 2026, not our quote. Your actual price depends on the part, the system and access, and you get that number from us before any work begins.
In Los Angeles County, most air conditioning repairs land between $339 and $488, with a service call and diagnosis running about $89 to $149. What decides your number is which part failed. A capacitor, the most common cause of a system that will not start, is roughly $175 to $400. A condenser fan motor is $200 to $700. A compressor is $1,200 to $2,800, which is usually the point where replacing the system makes more sense than repairing it. Those are published Los Angeles market ranges rather than our quote: we give you the exact price before any work starts.
| Job | Typical LA range | What moves the number |
|---|---|---|
| Service call and diagnosis | $89 to $149 | Waived or credited by some companies once you approve the repair. |
| Capacitor or contactor | $175 to $400 | The cheapest common failure, and the most frequent cause of a no-start. |
| Condenser fan motor | $200 to $700 | Less when the part is still under manufacturer warranty. |
| Most common repairs overall | $339 to $488 | The typical middle of the market for a straightforward fault. |
| Compressor replacement | $1,200 to $2,800 | Often the point where replacing the system beats repairing it. |
| Condenser replacement | $1,200 to $4,200 | Depends heavily on tonnage and refrigerant type. |
| Ductless mini-split, single zone | $2,000 to $6,500 | Per zone. Multi-zone systems run higher. |
| Ducted heat pump changeout | $8,000 to $18,000+ | Replaces the air conditioner and the furnace with one system, so compare it against doing both. |
| Full system changeout | $11,000 to $20,000+ | LA runs roughly 10 to 20 percent above the state average on labour and permits. |
California costs more than most states for a reason. Title 24 requires a permit and, on most changeouts, HERS verification by an independent rater. Labour is higher here, and older homes often need duct or electrical work the quote has to cover. A contractor who comes in far below these ranges is usually skipping the permit, and that surfaces at resale.
