AC Installation in the Inland Empire
Properly sized. Permitted. Done right the first time.
A new central AC system in the Inland Empire typically runs $4,500 to $12,000 installed, depending on system size, efficiency, and whether ductwork modifications are needed. We size every installation using a Manual J load calculation — not a guess, not "match the old unit." Undersized systems run nonstop and never cool the house; oversized systems short-cycle and create humidity problems.
We install central split systems, heat pumps, ductless mini-splits, and package units throughout Riverside County and San Bernardino County. Licensed (CA LIC# 1140776), permit included, manufacturer warranty registered on your behalf. Financing available.
How much does AC installation cost in the Inland Empire? A standard central AC replacement runs $4,500 to $12,000 installed — a 3-ton, 16 SEER2 system for a typical 1,500–2,000 sq ft home falls in the $5,500–$8,000 range. After the IRA tax credit ($600 for qualifying AC systems) and SCE rebates, the net cost is often $500–$1,200 lower.
AC System Types We Install
Every home is different. We match the system type to your home’s ductwork, layout, budget, and efficiency goals.
Central Split System AC
The most common installation type in the Inland Empire. A split system consists of an outdoor condenser/compressor and an indoor air handler or coil connected to your existing furnace. If your home has ductwork in good condition, a central split system delivers whole-home cooling at the best cost per square foot. We size the system using a Manual J load calculation — not a rule of thumb.
Heat Pump Systems
A heat pump delivers both cooling in summer and heating in winter using the same refrigerant cycle. For Inland Empire homeowners replacing aging equipment, a heat pump is worth serious consideration — especially with the federal IRA tax credit of up to $2,000 and SCE rebates for qualifying systems. Heat pumps are highly efficient in the IE's mild winters. We'll give you a full cost-of-ownership comparison vs. a traditional AC + furnace setup.
Ductless Mini-Split
The right choice for room additions, garages, older homes without ductwork, or converted spaces. A ductless system has no duct losses — significant in attic-run ducts where Inland Empire summer heat can raise duct temperatures dramatically. See our dedicated mini-split installation page for details on single-zone and multi-zone options.
Package Units
A packaged unit contains all components (compressor, coil, air handler) in a single outdoor cabinet, connecting to your home via ductwork through the exterior wall or rooftop. Common in certain Inland Empire home styles. All-in-one design simplifies service access and can be a good choice when interior mechanical space is limited.

Our Installation Process
From load calculation to city inspection — here’s what to expect.
Load Calculation & System Selection
We run a Manual J load calculation based on your home's square footage, insulation, orientation, window area, and local climate data. This determines the correct tonnage. We then walk you through equipment options (brand, efficiency rating, features) and provide a written, itemized quote.
Permit & Scheduling
We pull the required city permit. Installation is scheduled once the permit is issued — typically within 1 to 2 weeks. Permit timelines vary by city; we'll give you an accurate estimate for your jurisdiction.
Installation Day
Our crew arrives with the equipment staged and ready. Old equipment is removed and disposed of. New system is installed, linesets are run, electrical connections are made, and refrigerant is charged. The full installation typically takes one day for a standard replacement.
Startup, Testing & City Inspection
We start the system, run it through a full cooling cycle, measure temperature split, verify refrigerant charge, and confirm all controls are working. We schedule the city inspection and walk you through operating the new system. Manufacturer warranty registration is completed on your behalf.
Why Inland Empire Homeowners Choose Water Heater SOS
Proper sizing, every time
We run a Manual J load calculation on every installation — never size by rule of thumb or by matching the old unit. An oversized AC short-cycles and creates humidity problems; an undersized unit runs nonstop and never cools the house.
Licensed and insured
California Contractor License #1140776, C-20 classification. Required by CSLB for all HVAC work in California. We handle the permit and inspection — it's included in your installation quote.
IRA and rebate guidance
We know which systems currently qualify for the IRA tax credit and SCE rebates. We'll tell you the net cost after available incentives — not just the sticker price.
All major brands
Carrier, Trane, Lennox, Rheem, Goodman, York, American Standard, and Bryant. We recommend the brand and model that fits your home and budget — not what's surplus in the warehouse.
