Tired of AC Problems That Just Keep Coming Back?

Living with an outdated cooling system in Los Angeles or Ventura County costs more every month and gets worse every summer. Many homes across Thousand Oaks, Calabasas, Woodland Hills, Encino, Sherman Oaks, Camarillo, Oxnard, and Westlake Village still run AC units from the early 2000s, operating at 8-10 SEER while modern systems hit 16+ SEER2.
Common signs your AC needs replacement:
  • Struggles to keep up during hot Los Angeles summers
  • Leaves some rooms freezing while others feel like a sauna
  • Energy bills rising month after month with no clear cause
  • Frequent repairs that only buy you another season
  • System is 12+ years old and using R-22 refrigerant
You deserve a cooling system that works when you need it most. Constant AC failures shouldn’t interrupt your summer. Our AC installation services across Los Angeles and Ventura County help homeowners and property owners replace outdated, inefficient systems with modern SEER2-compliant equipment built for dependable performance, lower operating costs, and lasting comfort.

AC Installation & Replacement: What LA and Ventura County Homeowners Should Know

Installing or replacing an AC system in Los Angeles or Ventura County involves more variables than most homeowners expect. The questions that matter aren’t the same as what works in Arizona or Texas. Here’s what we evaluate during every free estimate:
  • Existing system age and refrigerant type. If your current AC is past 12 years old or uses R-22 refrigerant (phased out since 2020), replacement makes more financial sense than continued repairs. R-22 is increasingly expensive when leaks need recharging and the system is approaching end of life regardless.
  • SEER2 efficiency tier selection. California requires SEER2 compliance (the 2023+ standard) on new installations. We help you choose the right efficiency tier, going from SEER2 14 to SEER2 18+ costs more upfront but produces meaningful summer savings in valley homes that run AC heavily June through September.
  • Electrical panel capacity. Some older homes in the San Fernando Valley, Conejo Valley, and Ventura have 100-amp panels that may not support a high-efficiency AC or heat pump conversion. We assess panel capacity during the estimate and coordinate any upgrades if needed.
  • Ductwork condition. Existing ductwork can usually be reused for a new AC system. We inspect for leaks, insulation gaps, and undersized returns during the estimate. Sometimes ductwork sealing alone improves system performance by 15-20%.
  • AC vs heat pump decision. Most LA and Ventura homes that are replacing an aging AC can also replace their gas furnace at the same time by switching to a heat pump. We’ll show you both AC-only and heat pump options with full cost breakdowns so you can decide based on your priorities.
  • Permit and inspection requirements. LA Department of Building & Safety, Ventura County, and individual city jurisdictions each have specific permit requirements for HVAC installations. We handle the paperwork and coordinate inspections.
For homeowners considering the heat pump option, see our breakdown of heat pump costs in LA and Ventura County and our guide on replacing a furnace with a heat pump.

During your free in-home estimate we provide a written, itemized quote so there are no surprises

How long does AC installation take?

How fast can you schedule installation?

Most AC installations are scheduled within 5-7 business days of your free in-home estimate. During peak summer demand (June through September), we prioritize replacement scenarios where your existing AC has failed and you’re without cooling.

Should I replace my AC with a new AC or upgrade to a heat pump?

If your existing AC is past 12 years old or uses R-22 refrigerant, replacement is usually the smarter long-term move than another repair. The bigger question is AC-only versus heat pump. A heat pump replaces both your AC and gas furnace with one efficient system. For some homes it makes sense; for others, AC-only replacement is the better fit. During your free estimate, we’ll show you both options with real numbers. For more on the heat pump comparison, see our guide on heat pump vs furnace in LA and Ventura County.

What size AC do I need for my home?

We complete a Manual J load calculation that factors in square footage, insulation level, window count and orientation, ceiling height, and your local climate zone. Oversized AC units waste money and cycle inefficiently (short cycling damages compressors). Undersized units run constantly and never cool properly. The right-sized system runs efficiently and lasts longer.

What brands do you install?

We install all major AC and HVAC brands including Carrier, Lennox, Trane, Goodman, American Standard, Bryant, and Rheem. Each brand has different feature sets, efficiency tiers (SEER2 ratings), and warranty terms. During your estimate, we’ll walk you through which brand makes the most sense for your home, budget, and energy goals.

Do you handle permits and inspections?

Yes. We pull all required permits with LA Department of Building & Safety, Ventura County, or your specific city jurisdiction before installation. We also coordinate the final inspection with the city inspector. You don’t navigate the permitting process yourself.

Get My Free Estimate Today

Do you remove and dispose of the old AC unit?

Yes. We handle removal and proper disposal of your old AC system at no extra cost. Refrigerant is recovered and reclaimed per EPA Section 608 requirements (this is part of why working with a licensed and EPA-certified installer matters). Your space is left clean.

Get My Free Estimate Today

Do I need new ductwork for a new AC system?

Not always. We inspect your existing ductwork during the free estimate and only recommend replacement if it will materially improve efficiency, airflow, or comfort. Many existing ductwork systems can be reused with sealing or minor repairs. We don’t sell ductwork replacement you don’t need.

What rebates are available for AC installation in 2026?

As of 2026, SCE utility rebates remain available for qualifying high-efficiency AC installations and heat pump conversions. GoGreen Home Energy Financing is active.
