Service 07
The rules changed. We will tell you what applies to your building.
Refrigerants are being phased down, the California energy code was updated again, and equipment you could buy two years ago is no longer manufactured. You do not need to become an expert. You need a contractor who already is.

Scope
What owners and managers ask us
These are the questions we hear most. The honest answer is usually less alarming than the sales pitch.
Do I have to replace my R-410A equipment?
No. Existing systems can stay in service and be repaired. The change affects what new equipment is manufactured.
What about R-22 units?
They can still run, but refrigerant is scarce and costly. We help you plan replacement before a leak forces it.
What refrigerant will a new system use?
Most new equipment uses R-454B or R-32. They are mildly flammable, which changes some installation requirements.
Does my replacement need a permit?
In most California jurisdictions, yes, and the energy code adds its own requirements.
Do I have refrigerant reporting duties?
Larger refrigeration systems can fall under California registration and leak-inspection rules. We tell you if yours does.
Can I mix old and new components?
Rarely. Indoor and outdoor equipment generally needs to be matched to the same refrigerant.
Approach
How we help
Regulations are updated regularly and vary by jurisdiction and equipment type. This page is a general guide. We confirm the current requirements for your specific job before any work starts.
- Equipment assessment. Which of your systems are affected, and how soon it matters.
- Replacement planning. A phased plan that spreads cost across budget years.
- Code-compliant installation. Equipment, controls and ventilation installed to current requirements.
- Permits and inspections. Pulled, scheduled and closed out as part of the job.
- Air balancing and verification. Measured airflow and documented results from an NCI-certified balancer.
- Refrigerant records. Leak repairs and refrigerant use documented for your files.

Questions
Code Compliance & Refrigerant Transition: common questions
Is R-410A banned?
No. New residential and light commercial air conditioning equipment has moved to lower-GWP refrigerants under federal rules, but existing R-410A systems can keep operating and be serviced. Refrigerant for repairs remains available.
Are the new refrigerants safe?
R-454B and R-32 are classified as mildly flammable (A2L). Equipment is designed for them, and installation follows specific rules on charge limits, ventilation and leak detection. Installed correctly, they are safe.
What is Title 24?
It is California's building energy code. For HVAC it sets efficiency, controls, economizer, duct and verification requirements that apply when equipment is installed or replaced.
Will a new system cost more?
New-refrigerant equipment generally costs more than the models it replaced. We give you real numbers and compare them with the cost of keeping the old system running.
