Tired of AC Problems That Never Stay Fixed?

AC failures during a Los Angeles summer aren’t an inconvenience; they’re an emergency. From Thousand Oaks to Encino to Oxnard, the calls we get most often are the same: blowing warm air, no airflow, a unit that suddenly clicks off and won’t restart, or a breaker tripping every time the system kicks on. Most of these are diagnosed during the first visit, often resolved that day if parts are on the truck.
  • AC blowing warm air or no air at all (refrigerant leak, compressor issue, frozen evaporator coil, or capacitor failure)
  • Unit clicks on then immediately shuts off (failing capacitor, contactor problem, or thermostat fault, usually fixable in a single visit)
  • Frequent breaker trips when AC runs (overloaded compressor, electrical short, or undersized circuit, all diagnosable in 30 minutes)
  • One room hot, another freezing (zone damper failure, ductwork leak, blower motor issue, or refrigerant charge problem)
  • Outdoor unit running but indoor unit dead (blower motor, control board, or transformer, common on systems 8+ years old)
Don’t wait for a small fault to become a full system replacement. Same-day diagnostics across LA and Ventura County, written quotes before work begins, and no recurring charges for repairs we should have caught the first time. Call early for the fastest available appointment in most service areas.

Our AC Repair Services

Same-day diagnosis across most AC and HVAC systems whenever scheduling allows. Our EPA Section 608 certification means we handle every refrigerant type currently in use, from legacy R-22 to modern A2L refrigerants.
What We Fix:
  • Central air conditioning systems (split-system condensers and air handlers)
  • Central AC (ducted) and ductless mini-split systems
  • Heat pump cooling failures (refrigerant, defrost board, reversing valve issues)
  • Thermostat and airflow problems (smart thermostat compatibility issues, low airflow diagnosis)
  • Refrigerant leaks (R-22 phase-out scenarios, R-410A leak detection, A2L refrigerant handling)
  • Capacitor, contactor, and fan motor failures (the three most common AC repair causes)
  • Compressor faults (hard-start kit installation or full compressor replacement)
  • High and low voltage electrical issues (transformer, control board, wiring)
How We Work
  • Full system diagnostics before any repair quote, typically 30-45 minutes
  • Upfront written pricing before any work begins, no surprise charges
  • Clean workspace with boot covers indoors and debris removal outdoors
  • Post-repair performance testing to verify cooling output, refrigerant pressure, and amp draw before sign-off
We service most major brands, including Carrier, Lennox, Trane, Goodman, American Standard, Bryant, Rheem, and Daikin. We stand behind our workmanship. If a component we just replaced fails shortly after our visit, contact us and we come back at no diagnostic fee.

Our Promise:
  • Licensed and Certified: CSLB License #1135270, EPA Section 608 certified. Critical for AC repair since refrigerant handling without EPA certification is a federal violation, not optional.

  • Fast Same-Day Diagnosis: When you call, we work to get a technician to your home the same day in most cases. If parts are on the truck, most common repairs are completed during that visit. If parts need to be ordered, we give you a clear timeline upfront so you’re never left guessing.
  • $450 Flat-Rate Repairs: Most common AC repairs (capacitor, contactor, fan motor, thermostat, control board) are completed at our flat $450 repair rate. Major repairs (compressor replacement, refrigerant work) are quoted separately with written pricing before any work starts.
  • $75 Diagnostic Fee, Waived with Repair: Proceed with the repair and the $75 is waived, you only pay the flat $450 repair cost. Decline the repair and the $75 covers the technician’s time and travel.
  • Transparent Pricing: Written quote before any repair starts, no surprise charges, no upsells. You see the diagnostic finding and the cost before authorizing the work.
  • Diagnostic Honesty: If your AC is past the point where repair makes financial sense, we tell you. We don’t sell repairs that won’t last another season.

What LA & Ventura Homeowners Should Know About AC Repair

Not every AC failure needs a full system replacement, but not every failure is worth repairing either. Here’s the framework we use during diagnostics in LA and Ventura County.
  • The age threshold: If your unit is 10-12 years old and the repair quote is over $1,500, replacement usually wins on a 5-year TCO basis. Under 10 years, repair is almost always the right call. We give you the numbers, not a sales pitch.
  • The 2026 refrigerant transition: All new residential AC systems installed after January 2026 must use low-GWP A2L refrigerants like R-454B, replacing R-410A. If your unit is R-410A and needs major repair, we walk you through what that means for parts availability and future servicing cost.
  • The capacitor + contactor reality: These two parts cause roughly 60% of AC failures we see in the valley heat. Both are covered under our flat $450 repair rate, completed within the same visit. If another company quoted you $5,000+ for a ‘failed AC’ and the diagnostic notes mention capacitor or contactor, get a second opinion before you sign anything.
  • Compressor failures: A full compressor replacement on an older system runs $1,800 to $3,500 depending on size and refrigerant. If the rest of the system is past 10 years, this is usually the point where replacement makes more sense than continued repair.
  • Refrigerant leak detection: Slow leaks are common in systems 8+ years old. We use electronic leak detection and UV dye to find them. Topping off without finding the leak is a stopgap that costs the same money every season.
  • When same-day isn’t possible: Some repairs require parts that aren’t on the truck (specialty control boards, hard-to-source compressor replacements). In those cases we get the system stable, source the part the same day, and complete the repair within 24-48 hours.
If you’re weighing repair vs replacement, our breakdown of AC installation in LA and Ventura County and the heat pump cost guide for 2026 cover the replacement-side numbers. During your diagnostic visit we walk you through both scenarios.

Financing for Major Repairs and Replacement Options

Most AC repairs are straightforward and paid at completion. Major repairs (compressor replacement, full evaporator coil swap, control board on larger commercial units) can run $1,500 to $4,000 and may make financing worth considering, especially if the system is approaching the age where replacement is the smarter long-term move.
  • Flexible Payment Plans: Approved lender partners with terms designed for major HVAC work. Quick approvals, paperwork handled for you.
  • GoGreen Home Energy Financing for Replacements: If your repair quote suggests replacement makes more sense, the state-backed GoGreen program offers reduced-rate financing for qualifying California homeowners on new SEER2-compliant systems (3.58% to 9.48% APR for standard borrowers, 0% to 2% for LIDAC-qualifying low-to-moderate income households up to $30,000).
  • 2026 California Rebate Programs: Active rebates for AC and heat pump replacements include SCE utility rebates. We confirm what’s available for your specific scenario during the diagnostic visit.

Our Repair Promise

What most AC repair companies in LA call a ‘service guarantee’ is fine print and asterisks. Here’s what we actually commit to on every repair we do.
  • Diagnostic Honesty: If your AC is past the point where repair makes financial sense, we say so on the first visit, not after multiple service calls. We don’t sell repairs that won’t last another season just to bill another diagnostic fee next month.
  • Flat-Rate Pricing, No Hourly Surprises: Common repairs at our $450 flat rate, regardless of which component failed. Major repairs (refrigerant work, compressor replacement) quoted separately with the exact number before work starts. No hourly billing that creeps up during the visit. No “while we’re in there” upsells.
  • No Commission, No Upsells: Our technicians are mechanics, not commissioned “Comfort Advisors” with iPads. They diagnose the problem, quote the fix, and let you decide. If a $450 repair solves the issue, that’s what we charge. Never a $5,000+ replacement push when the actual problem is a capacitor or contactor.
  • Workmanship Backed by the Owner: If a component we just replaced fails shortly after our visit, contact us. We come back, no diagnostic fee on workmanship callbacks. Russ Teaca (CSLB Qualifier #1135270) personally stands behind every repair done by our team. No call center, no “your case has been escalated” runaround.

How much does AC repair cost in Los Angeles and Ventura County?

Most common AC repairs (capacitor, contactor, fan motor, thermostat, and control board issues) are completed at our flat $450 repair rate, parts and labor included. Major repairs are quoted separately: refrigerant recharges on R-22 systems run $400-$1,200, and full compressor replacements run $1,800-$3,500. You get a written quote with the exact number before any work starts.

Schedule My Repair

Do you charge a diagnostic fee?

Yes. We charge a $75 diagnostic fee for the on-site visit and full system assessment. If you proceed with the repair, the $75 is waived — you only pay the flat $450 repair cost. If you decline the repair, the $75 covers the technician’s time and travel.

Schedule My Repair

What brands and system types do you repair?

We repair all major HVAC brands including Carrier, Lennox, Trane, Goodman, American Standard, Bryant, Rheem, and Daikin. System types include central air conditioning, ducted and ductless mini-splits, and heat pumps in cooling mode.

Schedule My Repair

My AC is using R-22 refrigerant. Should I repair or replace it?

R-22 was federally phased out in 2020 and is now expensive when leaks need recharging. If your R-22 system needs a recharge and is 12+ years old, replacement with a modern SEER2-compliant system is usually the better long-term call. We give you the math during the diagnostic visit so you can decide.

Schedule My Repair

What if the same problem comes back after the repair?

We stand behind our workmanship. If the same component we just replaced fails again shortly after our repair, contact us and we’ll come back and make it right. We don’t offer a formal extended labor warranty on repairs (because additional components can fail independently after any repair), but if our work isn’t holding, we make it right.

Schedule My Repair

Can you handle emergency or after-hours AC repair?

We provide AC repair during standard business hours with same-day diagnosis in most cases. For genuine emergency or after-hours situations (full system failure during a heat wave, vulnerable family members, etc.), call as early as possible and we’ll do our best to accommodate. We don’t operate a 24/7 dispatch line.

Can regular maintenance prevent these repair calls?

My AC is old. How do I know if it’s worth repairing or replacing?

General rule: under 10 years and the repair is under $1,500, repair almost always wins. Over 12 years and the repair is over $1,500, replacement usually wins on 5-year TCO. Between those two thresholds, it’s case-by-case based on refrigerant type, system efficiency, and your plans for the property. We walk you through the numbers during the diagnostic visit. For replacement context, see our AC installation page or our heat pump cost guide for 2026.
