General Disclaimer & No Professional Advice

The sizing recommendations, calculators, guides, and product suggestions on this website are for general informational and educational purposes only. They are based on publicly available industry standards (AHAM, DOE, ACCA Manual J, NEC, etc.) and simplified assumptions that may not reflect your specific situation.

These tools do not constitute professional engineering, HVAC, electrical, plumbing, or installation advice. Sizing appliances involves site-specific factors — including but not limited to local building codes, actual load measurements, insulation values, climate variations, altitude, and safety requirements — that our calculators cannot fully account for.

Incorrect sizing or installation can lead to inefficiency, equipment damage, safety hazards, or code violations. You use this information and any recommendations at your own risk. Always consult a licensed local contractor, electrician, plumber, or professional engineer for your specific situation before purchasing or installing any appliance.

High-Risk Category Warnings

The following appliance categories involve significant safety, code, and installation risks. Extra caution is required:

• Generators: Improper sizing, installation, or operation can cause electrical shock, fire, carbon monoxide poisoning, or damage to connected equipment. Generator installations may require permits, transfer switches, and compliance with local electrical codes (NEC). Always consult a licensed electrician.
• Mini Splits / HVAC: Incorrect sizing leads to poor efficiency, inadequate comfort, or compressor damage. Refrigerant handling and electrical connections require licensed HVAC professionals. A full ACCA Manual J load calculation is recommended for accurate sizing.
• Sump Pumps: Improper sizing or installation can result in basement flooding and property damage. Battery backup, discharge line routing, and local drainage codes should be evaluated by a qualified professional.
• Water Heaters: Gas water heaters require proper venting and gas line sizing. Electric models may require dedicated circuits. Local codes may mandate expansion tanks, seismic strapping, or pressure relief valves.
• Dehumidifiers & Air Purifiers: While lower risk, improper sizing still results in poor performance and energy waste. Ensure proper drainage for dehumidifiers and adequate filter replacement schedules.
