Disclaimer / Assumption of Risk

Operator: Coldr LLC (“Coldr”).
Effective date: June 3, 2026

This Disclaimer / Assumption of Risk (this “Disclaimer”) is part of, and incorporated into, the Coldr LLC (“Coldr”) Terms of Service. By using the Coldr apps or the websites at coldr.app and app.coldr.app(the “Service”), you agree to it. If you do not agree, do not use the Service. Capitalized terms have the meanings given in the Terms.

1. Coldr is an assistive tool, not a substitute for professional judgment

1.1 Coldr provides guided diagnostics, field calculators (e.g., superheat, subcool, target charge), OEM fault-code lookups, an AI assistant, live Bluetooth instrument readings, and install/service guides. All of this is assistive professional information only. It is not engineering advice, not a certified diagnosis, not a code ruling, and not a substitute for the independent judgment of a licensed or otherwise qualified technician evaluating the actual equipment on site.

1.2 You — the qualified professional — remain solely responsible for every diagnosis, calculation result, charging decision, repair, installation, and safety determination. You must independently verify Coldr’s outputs against the equipment’s nameplate, the manufacturer’s published specifications and procedures, your instruments, and applicable codes before acting. Where Coldr’s output conflicts with manufacturer instructions, a listing/label, an applicable code, or your trained judgment, those control — not Coldr.

1.3 Safety-critical decisions remain yours. Decisions involving refrigerant handling, combustion, fuel gas, electrical work, pressurized systems, confined spaces, working at height, and life-safety controls can cause serious injury, death, property damage, or environmental harm if performed incorrectly. Coldr does not and cannot supervise your work or guarantee a safe outcome.

2. No warranty of accuracy

2.1 Calculations, diagnostic suggestions, fault-code interpretations, equipment and model data, install/service guides, cross-references, live readings, and AI assistant responses may be incomplete, outdated, generalized, or incorrect. Equipment behavior varies by make, model, configuration, environment, and condition.

2.2 The AI assistant is powered by a third-party large-language model (currently Google’s Gemini API) and can produce confident but wrong output (“hallucinations”). Treat AI output as a starting point to verify, never as an authoritative answer.

2.3 Live Bluetooth readings depend on third-party instruments, their calibration, pairing, and signal integrity. Coldr does not certify the accuracy of any instrument and is not responsible for measurement error.

2.4 TO THE FULLEST EXTENT PERMITTED BY LAW, COLDR DISCLAIMS ALL WARRANTIES REGARDING THE ACCURACY, RELIABILITY, COMPLETENESS, OR FITNESS OF ANY OUTPUT, consistent with Section 9 (Disclaimer of Warranties) of the Terms.

3. Your refrigerant-handling obligations — EPA Section 608

3.1 You are solely responsible for complying with Section 608 of the Clean Air Act (42 U.S.C. § 7671g)and the EPA’s implementing regulations at 40 C.F.R. Part 82, Subpart F, governing the maintenance, service, repair, and disposal of equipment that could release refrigerant.

3.2 This includes, without limitation: holding the appropriate EPA Section 608 Technician Certification (Type I, II, III, or Universal) for the equipment you service; following required practices for recovering, recycling, reclaiming, and not knowingly venting refrigerant; using certified recovery equipment; observing leak-repair and recordkeeping requirements; and complying with rules for newer refrigerants, including A2L and other lower-GWP refrigerants and their listed equipment.

3.3 Coldr does not certify you, does not perform recovery, and is not responsible for your refrigerant handling. Any A2L, charge, or refrigerant information in the Service is general reference only and does not relieve you of these obligations.

4. Your Massachusetts licensing obligations

You must hold, keep current, and work within the scope of every license, registration, or certification required for the work you perform, and must work only where you are lawfully permitted to do so. In the Commonwealth of Massachusetts, depending on the work, this may include (without limitation):

• Refrigeration / air-conditioning technicians and contractors — licensed under M.G.L. c. 146 and the related regulations (522 CMR and 528 CMR), administered by the Bureau of Pipefitters & Refrigeration Technicians within the Office of Public Safety and Inspections / Division of Occupational Licensure (DOL).
• Plumbers and gas fitters — licensed under M.G.L. c. 142 (and M.G.L. c. 112, §§ 61–65E) by the Board of State Examiners of Plumbers and Gas Fitters, under 248 CMR (including the Massachusetts Fuel Gas Code, 248 CMR 4.00).
• Electricians — licensed under M.G.L. c. 141 by the Board of State Examiners of Electricians (Certificates A/B/C/D), under the applicable electrical code (527 CMR 12.00 / Massachusetts Electrical Code).
• Sheet metal workers — licensed under M.G.L. c. 112, §§ 237–251, administered by the Board of Examiners of Sheet Metal Workers (board established under M.G.L. c. 13, § 101).

Coldr does not verify your licensure and is not responsible for work you are not licensed to perform.

5. Code and OSHA compliance

5.1 You are responsible for compliance with all applicable building, mechanical, fuel-gas, electrical, and energy codes, including the Massachusetts State Building Code (780 CMR) promulgated under M.G.L. c. 143, §§ 93–100, the Massachusetts Fuel Gas Code and plumbing/gas regulations (248 CMR), the Massachusetts mechanical and electrical codes, and any adopting amendments, together with all local permitting and inspection requirements.

5.2 You are responsible for compliance with all applicable occupational-safety requirements, including the federal Occupational Safety and Health Act and OSHA standards (29 C.F.R.) and any Massachusetts equivalents, including lockout/tagout, electrical safety, personal protective equipment, and confined-space rules.

5.3 Coldr’s guides and outputs do not constitute a code interpretation, a permit, an inspection, or a determination of compliance. The authority having jurisdiction (AHJ), the manufacturer’s instructions, and the adopted codes control.

6. Assumption of risk

You acknowledge that HVAC, refrigeration, gas, and electrical work is inherently hazardous and that relying on any tool — including Coldr — does not eliminate that risk. To the fullest extent permitted by law, you knowingly and voluntarily assume all risks arising from your use of the Service and from the work you perform, including risks of personal injury, death, property and equipment damage, environmental harm, regulatory penalties, and economic loss. You are responsible for verifying conditions, de-energizing and depressurizing systems, and using proper instruments and PPE.

7. Release and limitation

7.1 To the fullest extent permitted by law, you release Coldr and its owners, officers, employees, and contractors from claims arising out of or relating to your reliance on the Service or the work you perform, and you agree that the Limitation of Liability (Section 10) and Indemnification (Section 11) in the Terms apply to the subject matter of this Disclaimer.

7.2 Carve-out (non-waivable rights). Nothing in this Disclaimer limits or excludes any liability that cannot lawfully be limited or excluded under Massachusetts law, including liability for personal injury or death caused by our negligence, liability for fraud, and any non-waivable rights under the Massachusetts Consumer Protection Act, M.G.L. c. 93A. See Section 14 of the Terms. This Disclaimer allocates risk for the assistive, informational nature of the Service; it does not purport to waive what Massachusetts law says cannot be waived.

8. Acknowledgment

By using the Service, you confirm that you are a qualified professional (or working under qualified supervision), that you hold the licenses and certifications required for your work, and that you understand Coldr is an assistive tool whose outputs you will independently verify before acting.
