Estimates Only - Not a Manual J Calculation

All BTU estimates, capacity recommendations, and sizing figures produced by this site are general estimates based on simplified inputs. They are not a Manual J residential load calculation, which is the industry-standard method used by qualified HVAC professionals.

Manual J accounts for detailed factors - including full building envelope analysis, duct leakage, local design temperatures, infiltration rates, and occupant loads - that this calculator does not collect or model. Before purchasing any HVAC equipment, you should obtain a proper Manual J calculation from a licensed HVAC professional in your area.

No estimate from this site should be used as the sole basis for equipment selection, purchase, or installation.

Not Professional HVAC Advice

The content on this site is for general educational and informational purposes only. Nothing on WhatSizeMiniSplit.com constitutes professional HVAC design advice, licensed contractor recommendations, or an engineering opinion. Results vary based on your specific home, climate, construction, and usage patterns. A qualified HVAC professional should always review your situation before any equipment is purchased or installed.

Not Electrical Advice

Circuit requirements vary by equipment and installation. This site does not provide electrical design guidance. All electrical requirements for HVAC equipment must be confirmed with and performed by a licensed electrician in accordance with local codes.

Not a Contractor Quote

Nothing on this site is a contractor quote, project estimate, or bid of any kind. We do not connect users with contractors, installers, or service providers. Any pricing or cost ranges referenced on this site are general planning-level figures based on publicly available market data and are provided solely for budgeting context - not as a guarantee of actual project cost.

Cost Estimates Are Planning Ranges Only

Where cost figures appear on this site, they represent broad regional planning ranges drawn from publicly available data. Actual costs depend on your local labor market, equipment selection, home characteristics, permit requirements, and contractor pricing. Always obtain multiple quotes from licensed local contractors before budgeting a project.
