We review messages related to calculator accuracy, content corrections, and general site feedback.

What to include (so we can help faster)

• Which page/tool: paste the URL of the calculator or page
• What you expected vs what happened: one sentence is fine
• Your inputs: room length/width, ceiling height, climate/region, etc.
• Screenshot (optional): helpful for mobile or formatting issues
• Your device/browser: e.g., iPhone Safari, Android Chrome, Windows Chrome

Tip: If you’re reporting a calculation issue, include the result shown and the units (BTU/hr, tons, kW, etc.).

What we can’t do

While we’re happy to fix errors and improve the calculators, we can’t provide personalized HVAC design, installation instructions, or code/permit guidance for your specific home.

This includes whole-home equipment selection or duct design (Manual J / Manual S / Manual D), electrical, gas, refrigerant, or permit/code compliance advice, diagnosing comfort issues without an on-site assessment, and emergency or safety troubleshooting.

For these situations, please consult a qualified HVAC professional in your area. You can get a free HVAC quote to connect with local contractors.
