I will do mini split sizing and zoning for your adu, garage or room addition

Sizing a mini split for an ADU, garage or room addition? Guessing by square footage is how people end up with a unit that short cycles in summer or can't keep up in winter.

I'm a mechanical engineer. I run a room by room load calculation for your space, then size the mini split to match it, including how many zones you need and where the indoor units should go.

What you get:

1. Cooling and heating load in BTU per hour
2. Recommended indoor unit and outdoor unit capacity
3. Zoning plan: how many heads and where
4. Heating capacity check at your winter design temperature
5. PDF report you can give to your installer or supplier

Projects I handle: ADUs, converted garages, sunrooms, room additions, basements and home offices.

What I need from you: a floor plan or room sizes, window sizes and direction, insulation if known, your city and ZIP code, and a photo of the space.
