HVAC Marketing in the Inland Empire: permitted AC and furnace replacement estimates in California's big inland metro

The Inland Empire is a metro of nearly 4.8 million people where seven in ten homes heat with gas. Riverside and San Bernardino counties hold close to a million owner-occupied homes, most of them built from the 1980s to the 2000s. Summer arrives late and stays into October. And in California, a changeout is a permitted job with field testing, which shapes how the ads should read.

Why is the Inland Empire an AC plus furnace market?

Because 70.9% of occupied homes in the metro heat with utility gas and only 21.4% with electricity. That is the reverse of Florida or much of Arizona. Most replacement jobs here are a condenser, coil and gas furnace, not a heat pump swap, so the lead offer is a full AC and furnace changeout.

The climate explains why both halves wear out. NOAA's 1991 to 2020 normals for Riverside Municipal Airport show 100.5 days a year at 90°F or more and 21.7 at 100°F or more, with a July normal high of 93.3°F. Winter is mild, with a January normal low of 43.6°F and 3.5 freezing nights, but 1,386 heating degree days still keep furnaces running.

Which Inland Empire homes are replacement age?

Most of them. Across the metro, 534,201 of 977,126 owner homes (54.7%) were built from 1980 to 2009, and another 32.9% before 1980. Only 12.4% were built in 2010 or later. The two counties differ: Riverside County is newer and more owner-occupied; San Bernardino County is older.

Four in ten San Bernardino County owner homes predate 1980, and in the City of Riverside it is six in ten. Those estimates can turn into duct replacement conversations, which in California brings its own testing rules. Riverside County's 1990s and 2000s tracts are the bigger pool of straightforward system changeouts.

What California rules change an Inland Empire changeout?

Permits, HERS testing and licensing. The California Energy Commission says HERS testing may be mandatory depending on the work, and properly permitted work triggers any testing needed. The CEC also says a contractor should explain permit requirements to the homeowner, with HERS testing part of that discussion.

What that looks like locally: the City of Colton's HVAC permit handout lets the owner or a licensed C-20 contractor (or a B contractor under the multi-trade rule) pull the permit, and requires a CF1R alteration form at application, and CF2R and CF3R forms at final inspection. For a changeout of the condenser, coil or air handler it lists duct leakage, airflow and refrigerant charge checks, with exemptions such as a duct system with less than 40 linear feet in unconditioned space. Colton's handout was written for the 2019 code; your own permit office sets the current list.

For marketing, this is a feature, not a hurdle:

• Ads say "permitted install." The homeowner learns up front that the job includes a permit and testing, so your price is judged against other permitted bids, not a cash swap.
• The qualifier asks about ducts. Homes with long duct runs in unconditioned space are more likely to need leakage testing and sealing, so the estimate is priced with that in mind.
• Your license goes on the landing page. The CSLB C-20 classification covers warm-air heating, ventilating and air-conditioning systems with their ducts and controls.

Which rebates can Inland Empire ads use?

A gas furnace rebate across most of the metro, and a city rebate in Riverside. Southern California Edison delivers power across central, coastal and Southern California, and its rebates page says the statewide Comfortably CA program does not offer direct customer incentives. We found no current SCE central AC or heat pump rebate.

What we could verify:

• SoCalGas furnace rebate (2026). ENERGY STAR gas furnaces qualify at $1.40 per kBtuh (92 to 94% AFUE), $10 per kBtuh (95 to 96%) and $25 per kBtuh (97% or higher). A licensed contractor must install it, proof of permit closure is required before payment, and applications must be postmarked by December 31, 2026. At 80,000 BTU/h, the top tier works out to $2,000.
• Riverside Public Utilities. For RPU electric customers only: $150 per ton for central AC at 15.2 to 15.9 SEER, $250 per ton at 16 SEER or greater, and $750 per ton for electric heat pumps at 15.2 SEER or greater. The condenser and evaporator coil must match, and the application is due within 90 days of purchase.
• State heat pump incentives. TECH Clean California's single-family heat pump HVAC incentives have been reserved statewide since November 14, 2025. We keep them out of ads.

The RPU heat pump rebate is large enough to change the offer inside Riverside city limits: a 4-ton heat pump works out to $3,000. So city of Riverside homes get their own ad set that leads with a heat pump option, while the rest of the metro leads with AC plus furnace and the SoCalGas tier.

How would we draw the Inland Empire ad map?

By where your trucks already go. The metro reached 4,769,007 people in 2025, up 3.6% since 2020, with Riverside County up 5.2% and San Bernardino County up 1.9%. Builders pulled 9,977 single-family permits across the metro in 2025, but only 160 in the City of Riverside.

A metro this size cannot be covered well at $4,000 a month. We start with one corridor: for example, Riverside, Corona and Jurupa Valley, or Rancho Cucamonga, Ontario, Fontana and Chino, or Temecula, Murrieta and Menifee. The territory is still yours for the whole metro. Riverside's climate normals do not describe the High Desert or the Coachella Valley, so if you serve those areas we plan from their own stations.

When does the Inland Empire cooling season peak?

Late. Riverside averages 12.1 days at 90°F or more in June, then 23.8 in July, 25.2 in August, 18.9 in September and 9.0 in October. That puts the strongest Google months from July to September, with October still warm enough for replacement searches.

Each lead answers six questions (home type, current system and age, replacement or repair, timing, budget, owner or renter) before it reaches your calendar. In the Inland Empire the qualifier also asks the gas and power company, so rebate wording only reaches homes that can use it.

Here a booked estimate means a qualified homeowner scheduled for an in-home visit at a set time on your calendar. These are planning assumptions, not California data. Lead costs in a metro next to Los Angeles may run higher than our assumption, and your first month replaces these numbers.

Is the Inland Empire territory open?

Yes. The Inland Empire is open, one contractor per service line across Riverside and San Bernardino counties. Your account would be run by Sam (audit, strategy, media buying) and his brother Alan (onboarding, CRM, operations). We are based in Sydney, work Pacific Time hours, and have no California office, staff or clients.

You keep ownership of the ad accounts, the landing page on your domain and the CRM where every lead sits. See the HVAC Profit Machine, AC replacement leads, pricing, or book a strategy call.
