A company bought a tetrafluoroethane reclaimer machine to recapture refrigerant from truck air conditioners during repairs, instead of letting it vent into the atmosphere. Is the machine exempt from Texas sales and use tax because it protects the environment?

Plain-English summary

A company that maintains a fleet of trucks bought a tetrafluoroethane reclaimer machine to use while repairing the trucks' air conditioning systems. The machine hooks up to a truck's A/C unit, pulls out the tetrafluoroethane refrigerant and stores it in an internal tank while repairs are made, then pumps the refrigerant back into the unit afterward — preventing the refrigerant (a pollutant) from escaping into the atmosphere during the repair. The company asked whether the machine's purchase was exempt from Texas sales and use tax, given its environmental-protection function.

The Comptroller's answer was a short, direct no: the purchase of the reclaimer machine is subject to sales tax, because the Tax Code contains no exemption for equipment purchased for use in repairing air conditioning systems — the machine's environmental benefit (keeping refrigerant out of the atmosphere) does not itself create a tax exemption.

What this means for you

Fleet operators and repair shops buying environmental/recovery equipment

Don't assume that equipment serving an environmental-protection purpose (like refrigerant recovery, emissions capture, or similar recycling/reclaiming machines) is automatically tax-exempt. Absent a specific statutory exemption naming that type of equipment or purpose, general repair/maintenance tools remain taxable regardless of their environmental benefit.

Businesses evaluating "green" or environmentally-motivated equipment purchases

The environmental rationale behind buying a piece of equipment is not, by itself, a basis for a sales tax exemption in Texas. You need to identify (and confirm you qualify for) a specific statutory or rule-based exemption — general environmental benefit alone won't get you there.

Accountants and tax professionals

This is a clean, narrow ruling: no statute or rule was cited because none applied — the Comptroller simply confirmed the absence of any applicable exemption for this category of equipment.

Common questions

Q: Is equipment used to recover and protect the environment automatically exempt from Texas sales tax?
A: No. Without a specific statutory exemption for that equipment or purpose, the general environmental benefit does not create a tax exemption.

Q: Is a tetrafluoroethane reclaimer machine used for truck A/C repairs exempt from Texas sales/use tax?
A: No — its purchase is subject to Texas sales tax, per this letter.

Q: Why didn't the Comptroller cite any statute in the ruling?
A: Because there was no applicable exemption to analyze — the ruling simply confirms the absence of one for this type of equipment/purpose.

Q: Can I rely on this letter for my own equipment purchase?
A: No. It's based on the facts presented, and the letter notes the opinion may change on additional or different facts.

Citations and references

No specific statutes or rule numbers were cited in this letter — the Comptroller confirmed no exemption exists in the Tax Code for this type of equipment.

Original ruling text

April 22, 1998

Dear Ms. **:

Thank you for your recent letter which is restated in part with response below.

Our company purchased a tetrafluoroethane reclaimer machine for use while
repairing the air conditioning systems for our fleet of trucks. This machine
hooks up to the system in the air conditioner, pulls the solution from the unit
and stores it in a tank in the machine. After the unit's repairs are made, the
reclaimer pumps the tetrafluoroethane back into the air conditioner unit.
Hence, our environment is protected from the pollutant not escaping into the
atmosphere.

Is this item exempt from Texas sales and use tax?

Response: Purchase of the tetrafluoroethane reclaimer machine is subject to
sales tax. The Tax Code contains no exemption for its purchase for use in
repairing air conditioning systems.

This opinion is rendered based on the facts presented. If there are additional
or different facts, the opinion may change.

You may call me toll free at 1-800-531-5441, ext. 3-4680. The direct line is
