A new AC is only as good as the load calculation behind it, and in a city where elevation swings the real cooling need more than the citywide average suggests, that matters more than most places. We size every Agoura Hills installation for the actual property, not a generic "mild city" guess, and back the work with our installation warranty.
Repairing an aging system is not always the wrong call, but on a property that was sized off the wrong assumption from the start, a repair only delays the real fix. These are the clearest signs it is time to plan a new installation.
If a previous system was sized off a general "Agoura Hills is mild" estimate but your property sits low near the freeway rather than up in the hills, it may have been undersized from day one. A real load calculation catches this the second time around.
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.
Homes near the Reyes Adobe historic district often run ductwork that predates modern insulation and cooling standards. A new condenser paired with undersized returns still underperforms, no matter the tonnage.
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.
Detached guest houses on canyon and lakeside lots are common but rarely built with ductwork run to them. A dedicated ductless zone is usually simpler than extending the main system across a long, terrain-driven run.
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.
Agoura Hills is one of the trickier cities on our service map to size correctly, precisely because it runs cooler than the inland Valley on average. That citywide number tempts a lazy estimate, but a property down near the 101 corridor sees meaningfully more direct heat than a home higher into the hills near Ladyface Mountain, and sizing off the average rather than the specific lot is exactly how a new system ends up undersized before it is even installed. We run a full Manual J load calculation for every installation and factor in elevation and sun exposure, not just square footage.
Terrain changes the installation itself, not just the tonnage. Canyon and lakeside properties around Malibou Lake often need longer refrigerant line runs given the lot layout, and a detached guest structure typically calls for its own ductless zone rather than an extended run from the main system. Older homes near the Reyes Adobe historic district add a different consideration, since original ductwork here rarely matches modern static pressure requirements, so we evaluate duct condition before recommending equipment rather than after it is already on order.
We measure the home, inspect existing ductwork, and run a Manual J calculation that accounts for your property's actual elevation and sun exposure, not a citywide average.
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 Agoura Hills, including canyon and lakeside properties.
| 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 |
| Ductless zone for a guest structure | $3,500 – $6,500 |
| High-efficiency upgrade (18+ SEER2) | Add $1,500 – $4,000 |
| New or replacement ductwork | $2,000 – $6,000 |
