Calabasas homes tend to run bigger than average, from single-story estates off Mulholland Highway to properties with a detached guest house, and a new AC is only as good as the load calculation and zoning behind it. We size every Calabasas installation for the actual property, not a generic square footage guess, and back the work with our installation warranty.
Repairing an aging system is not always the wrong call, but on a larger Calabasas property it can also mask a sizing problem that was never fixed the first time. These are the clearest signs it is time to plan a new installation instead.
A single central unit trying to cool a sprawling single-story home or a property with a detached guest house rarely keeps every room comfortable. That is a sizing and zoning problem, not something a repair visit can fix.
Properties rebuilt since 2018 often have all-new electrical and structural work but were left with a builder-grade HVAC system chosen for cost rather than the home's actual layout. A fresh load calculation usually turns up real gaps.
Detached structures are common on Calabasas lots but were rarely built with ductwork run to them. A dedicated ductless zone is usually a faster, less invasive fix than extending the main system.
Older construction around Old Town Calabasas was often ducted for a smaller cooling load than today's expectations. Undersized returns and trunk lines choke even a correctly sized new condenser.
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.
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.
Calabasas is one of the few cities on our service map where the average home genuinely runs bigger than the equipment most contractors default to. A single-story estate over 3,500 square feet, common in the gated communities off Mulholland Highway, almost never cools evenly off one central unit no matter how large that unit is. We run a full Manual J load calculation and a zone assessment for every installation here, and for a property that size the honest answer is usually a multi-zone system rather than one oversized condenser working overtime.
Age and construction era matter just as much as square footage. Homes near the Leonis Adobe and Old Town Calabasas often have original ductwork that was never sized for modern cooling demand, so a new system paired with undersized returns will underperform regardless of tonnage. Properties rebuilt since the 2018 Woolsey Fire are the opposite case, usually with all-new construction but an HVAC system picked during the rebuild that was never actually load-calculated for the finished home. Either way, we inspect the ductwork and the structure together before quoting equipment, not after.
We walk the property, measure square footage per zone, and run a Manual J calculation, including any detached guest house or pool house that needs its own system.
You get a clear, itemized quote showing the equipment, zoning plan, SEER rating, and total cost before anything is ordered.
We coordinate with your HOA or gate staff ahead of time so scheduled access is never a holdup, then remove old equipment and install to manufacturer and code specifications.
We verify refrigerant charge with digital gauges, test airflow and balance across every zone, and walk you through the new thermostat before we leave.
Final pricing depends on tonnage, zoning, and your home's specific ductwork condition. These are typical ranges for a full installation in Calabasas, where multi-zone systems come up more often than in a typical Valley neighborhood.
| 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 |
| Multi-zone system (3 to 4 zones) | $12,000 – $22,000 |
| Ductless zone for a guest house or pool house | $3,500 – $6,500 |
| High-efficiency upgrade (18+ SEER2) | Add $1,500 – $4,000 |
