Disclaimer
Please read this before acting on anything you find here.
Information only, not professional advice
ComfortCalc publishes general educational information about heating, cooling, and home comfort. It is not professional, engineering, electrical, or contracting advice, and it is not a substitute for a licensed HVAC technician, electrician, or other qualified professional assessing your specific equipment and situation. Codes, equipment, and conditions vary, and only a professional who inspects your system can tell you what is safe and correct for it.
Safety and assumption of risk
Some of our articles describe repairs and maintenance that involve real hazards, including high-voltage electricity, stored electrical charge in capacitors, gas, refrigerant, and moving parts. These tasks can cause serious injury, death, property damage, or fire if done incorrectly. Certain work, such as handling refrigerant, is also regulated by law and may require certification or a licensed professional. If you choose to act on any information here, you do so entirely at your own risk. When you are not certain you can do a task safely and legally, stop and hire a qualified professional.
No warranty
We work to keep our calculators and content accurate, but we make no warranty, express or implied, about the accuracy, completeness, or fitness for any purpose of anything on this site. Calculator results are estimates for general guidance, not a substitute for a proper load calculation (such as a Manual J) by a professional. Verify anything important before you rely on it.
Limitation of liability
To the fullest extent permitted by law, ComfortCalc and its authors are not liable for any loss, injury, or damage of any kind arising from your use of, or reliance on, this site or its content. Your sole remedy if you are dissatisfied is to stop using the site.
Affiliate disclosure
Some links on this site are affiliate links, including to Amazon, which means we may earn a commission if you buy through them at no extra cost to you. A commission never changes a recommendation. We point to products we believe are a good fit based on research, not on who pays the most.
External links
We sometimes link to other websites for convenience. We do not control and are not responsible for their content, accuracy, or practices.
By using ComfortCalc you agree to this disclaimer. We may update it from time to time, and continued use means you accept the current version.
