Whether you are along the flatter Ventura Boulevard corridor or higher toward the Topanga foothills, a new AC is only as good as the installation behind it. We size every Tarzana system with a real load calculation, not a square footage guess, and back the work with our installation warranty.
Repairing an aging system is not always the wrong call, but sometimes a new install is the smarter financial decision. These are the clearest signs it is time to stop repairing and start planning a replacement.
Most residential AC systems are built to last 12 to 15 years. Past that mark, efficiency drops and the odds of a major component failure rise sharply, even with regular maintenance.
If you have called for repairs more than twice in the last two summers, or a single repair quote is approaching half the cost of a new system, replacement usually saves money over time.
An aging or undersized system loses efficiency gradually. If your cooling bills have crept up without a change in habits, the system is likely working harder than it should to do the same job.
R-22 was phased out of production in 2020. If your system still uses it, refrigerant for a leak repair is expensive and getting harder to source, and replacement is often the more practical route.
Some rooms cold, others warm, no matter the thermostat setting, often means the system was undersized or poorly matched to the home from the start, not just a maintenance issue.
A system that short cycles or runs nearly nonstop is either the wrong size for the home or losing efficiency fast. Either way, a proper load calculation on a new install usually resolves it for good.
Tarzana was developed on a genuine elevation split, and the original 1920s Tarzana Tract sales brochures even marketed it, promising buyers "high elevation" and "cool, liveable surroundings." That split is still real today: homes along the flatter Ventura Boulevard corridor sit lower and see more direct afternoon sun, while properties higher toward the Topanga foothills to the south catch more airflow but face different exposure. We run a full Manual J load calculation for every installation built around where the home actually sits, not a single Valley-wide average.
Property type changes the installation itself, not just the tonnage. Older buildings along the commercial Ventura Boulevard corridor often need a full duct evaluation before new equipment goes in, while a home higher toward the foothills may need a different unit placement or longer line set given the terrain. We plan for that during the initial site visit, not after the equipment is already on order.
We measure the home, inspect existing ductwork, and run a Manual J calculation to determine the correct tonnage for your specific property.
You get a clear, itemized quote showing the equipment, SEER rating, and total cost before anything is ordered.
Old equipment is removed, new line sets are brazed, and the system is installed to manufacturer and code specifications, typically in a single day.
We verify refrigerant charge with digital gauges, test airflow at every vent, and walk you through the new thermostat before we leave.
Final pricing depends on tonnage, SEER rating, and your home's specific ductwork condition. These are typical ranges for a full installation in Tarzana.
| System Type | Typical Range |
|---|---|
| 2 to 2.5 ton, standard SEER2 | $5,500 – $8,500 |
| 3 to 3.5 ton, standard SEER2 | $6,500 – $9,500 |
| 4 to 5 ton, standard SEER2 | $8,000 – $12,000 |
| High-efficiency upgrade (18+ SEER2) | Add $1,500 – $4,000 |
| New or replacement ductwork | $2,000 – $6,000 |
