The Problem
When It's Time for a New AC System
Your current AC system is telling you something. Maybe it’s running constantly but barely keeping up. Maybe the repair bills are adding up faster than you’d like. Or maybe it’s 15+ years old and still running on R-22 refrigerant that’s no longer manufactured.
A new system isn’t just a fix — it’s an upgrade. Today’s equipment is significantly more efficient, quieter, and more reliable than what was available even 10 years ago. The right installation pays for itself through lower energy costs, fewer repairs, and better comfort in every room.

What We Do
What We Install
Every installation starts with a Manual J load calculation — the engineering standard for residential HVAC sizing. This ensures your new system matches your home’s actual cooling load, not a quick estimate based on square footage alone.
Central Air Conditioning
Split systems and packaged units from leading manufacturers including Carrier, Trane, Lennox, and Goodman. We install the right brand and model for your home’s needs and your budget.
Ductless Mini-Splits
Ideal for homes without ductwork, room additions, or supplemental cooling. We’re factory-authorized installers for Mitsubishi, Daikin, and Fujitsu.
Heat Pump Systems
Dual-function heating and cooling in a single system. An increasingly smart choice for the Los Angeles climate, where heating demands are moderate and efficiency matters year-round.
System Changeouts & Upgrades
Replacing an existing system with a higher-efficiency unit, including any necessary ductwork modifications, electrical upgrades, or thermostat replacements.

AC Installation — Common Questions
What homeowners ask when replacing an old system or installing AC for the first time.
How much does a new AC system cost?
Residential AC installation in Los Angeles typically ranges from several thousand dollars for a basic replacement to significantly more for a high-efficiency system or a complete ductwork overhaul. The actual cost depends on system type, efficiency rating, home size, and whether ductwork modifications are needed. We provide exact pricing in your free estimate — no ranges or asterisks.
How long does installation take?
A standard system replacement — same type, same location — is typically completed in one day. Installations that involve new ductwork, relocating equipment, or switching system types (such as adding ductless mini-splits) may take 2 to 3 days. We’ll confirm the timeline before work begins.
Should I repair my current system or replace it?
What size AC system do I need?
The right size comes from a Manual J load calculation, not a square footage estimate. We measure your home, assess insulation, window area, orientation, and other factors to determine the exact cooling load. Oversized systems waste energy and create humidity problems. Undersized systems can’t keep up on hot days. Proper sizing is the single biggest factor in long-term performance.
