Yes, the EPA requires strict refrigerant logs and documentation under Section 608 of the Clean Air Act.
Why Track Refrigerant Usage? The main purpose of tracking your refrigerant usage is regulatory compliance. All refrigerant regulatory compliance requires some form of refrigerant usage tracking.
The Environmental Protection Agency (EPA) regulates refrigerants primarily to reduce greenhouse gas emissions and protect the ozone layer. Key, up-to-date regulations span the American Innovation and Manufacturing (AIM) Act and Section 608 of the Clean Air Act.
This seemingly technical change has a major practical implication: virtually every commercial HVAC and refrigeration system now requires detailed record-keeping and leak rate monitoring. Under EPA regulations, equipment owners and operators are responsible for refrigerant compliance.
Starting January 1, 2026, the EPA will lower the refrigerant threshold from 50 pounds to 15 pounds for systems containing high-global warming potential (GWP) refrigerants, a change that will significantly expand regulatory oversight and bring many previously exempt systems under federal scrutiny.
The $5,000 rule is a guideline to help homeowners decide whether to repair or replace their HVAC system. You multiply the age of your unit by the cost of the needed repair. If that number exceeds $5,000, replacing your HVAC system is often more cost-effective.
The EPA’s phase-down of the hydrofluorocarbon (HFC) R-410A is actively underway, having officially banned the manufacturing and importing of new residential R-410A air conditioning and heat pump systems in 2025. It is now illegal to install most new R-410A systems, as the industry transitions to lower-GWP alternatives.
Although R32 has a lower global warming potential compared to other common refrigerants, it is still mandatory to recover this refrigerant from end of life air conditioning and refrigeration systems or during maintenance on the refrigeration circuit.
Both 608 and 609 is EPA certified. While the two certifications differ in the type of refrigeration systems covered (automotive vs. stationary) and the specific content of their exams, they both play a vital role in protecting the environment and the public.
Yes, it is strictly illegal to release or "vent" Freon and other refrigerants into the atmosphere. This is regulated federally by the U.S. Environmental Protection Agency (EPA) under the Clean Air Act.
Yes, eligible R-410A equipment can still be legally installed.
This translates into the so-called “Refrigeration Cycle”. In this, the refrigerants are transformed to be able to extract heat from the environment and produce cold. This cycle comprises four stages: compression, condensation, expansion, and evaporation.
Refrigerant can only be sold to technicians certified under the Section 608 or Section 609 technician certification programs, where individuals may only purchase refrigerant consistent with the appliances covered by their certification.
Starting January 1, 2025, the manufacturing or importing of any product in specified sectors that uses a regulated substance with a global warming potential of 700 or greater is prohibited (40 C.F.R. § 84.54(a)). The specified sectors listed include R-410A, the most common refrigerant used in the HVAC industry.
The 3-minute rule is an HVAC safety guideline that requires waiting at least three minutes after turning off an air conditioner before restarting it. This brief pause allows refrigerant pressures inside the system to equalize, preventing severe strain on the compressor and costly electrical or mechanical breakdowns.
If you are referring to the EPA Section 609 test, I believe it is an open book test. 608/609 are easier than the ASE A7 but if you are familiar with none of them are bad. It's more about refrigerant handling than AC repair. It's very very easy if you know how HVAC works.
Yes, you can buy refrigerant with an EPA Section 609 certification, but only for automotive air conditioning (MVAC) systems and in containers of 2 pounds or more.
HVAC Sales
Annual Range: $170K-$200K, Depending on Experience. Top Performers making $300K-$460K.
Getting your EPA 608 certification costs between $10 and $300+, depending on the provider and your study needs. Standalone exam fees range from $30 to $85, while comprehensive packages including study materials, proctoring, and unlimited test attempts typically cost between $80 and $150.
No, R-32 is not obsolete; it is currently one of the primary modern replacements for older, high-global-warming refrigerants like R-410A.
A2L refrigerants, the new refrigerants for 2026, will replace R-410A in new systems. A lot about A2L refrigerants is explained in their name: The “A” means low toxicity. The “2L” is a safety classification, indicating it is mildly flammable.
Yes, R32 requires gauges specifically rated for A2L (mildly flammable) refrigerants and the higher operating pressures associated with R32 systems.
Short answer: Yes. Eligible R410A systems manufactured before January 1, 2025, can still be installed in 2026 under the Technology Transitions Rule issued by the U.S. Environmental Protection Agency. There is no nationwide ban on the installation of compliant R410A equipment.
Yes, you can still buy R-410A equipment. While the production and import of new R-410A systems were banned at the manufacturer level starting January 1, 2025, retailers and contractors are still legally permitted to sell and install existing overstock manufactured before the cutoff date.
One of the primary reasons for the switch from R-134a to 1234YF refrigerant is environmental impact. Traditional refrigerants like R-134a contribute significantly to global warming. While R-134a doesn't harm the ozone layer like older refrigerants (such as R-12), it still has a high Global Warming Potential (GWP).
