What's changed for HVAC in 2025 and 2026
New refrigerants. Since January 1, 2025, new residential air conditioners and heat pumps use lower-GWP refrigerants such as R-454B. Your existing R-410A system can still be repaired, but the new refrigerants aren't a drop-in swap, so a replacement means a matched outdoor unit and indoor coil.
SEER2 efficiency. In the Southwest, new split air conditioners and heat pumps have to meet SEER2 minimums, so today's systems use less power than the units many valley homes were built with.
Permits and testing. Under California's Title 24 Energy Code, replacing an outdoor unit, air handler or coil usually requires a permit, duct leakage testing and third-party verification. We'll walk you through what your job needs.
Rebates. Programs change often. The federal 25C heat pump tax credit ended for systems installed after December 31, 2025, so we'll help you check current SCE, SDG&E and state programs before you buy.
Is a heat pump right for your home?
With hot summers and mild winters, Temecula-area homes are a strong fit for heat pumps, especially homes on propane or all-electric power.
Frequently asked questions
Do you charge extra for nights or weekends?
No. Code Blue provides 24/7/365 service with no extra fees for evening or weekend calls.
Do you offer free estimates?
Yes. We offer free estimates on new systems and free second opinions if another company has quoted you a repair or replacement.
What brands do you work on?
All major makes and models, including Rheem, Trane, Carrier, Lennox, Goodman, Amana, American Standard, Mitsubishi Electric, Daikin, LG and Fujitsu.
Are your technicians paid on commission?
No. Our full-time technicians are paid hourly, not on commission, so their recommendations aren't driven by sales. They're NATE-certified and background-checked, and we don't use subcontractors.
Can my old R-410A air conditioner still be repaired?
Yes. Existing R-410A systems can still be serviced and recharged. Since 2025, new equipment uses lower-GWP refrigerants like R-454B, which is not a drop-in replacement. We'll explain whether a repair or a matched replacement makes more sense for you.
Do you offer financing?
Yes. We offer financing through multiple lending options for qualified customers. Ask us when you schedule your estimate.
