How to write an AC installation estimate
A mini-split installation has many variables: line set length, height, condensate drain routing, whether a dedicated circuit is needed. If they're not in the estimate, they show up as surprises on installation day.
What to measure on site
- Line set length between the indoor and outdoor units.
- Where the outdoor unit goes and whether you need a bracket, pad or work at height.
- Condensate drain route.
- Whether the electrical service can handle the unit or a dedicated circuit is needed.
- Wall penetration: material and thickness.
What to include in the line items
- Standard installation, with the line set length included.
- Additional line set, per foot or meter.
- Outdoor unit bracket or pad.
- Dedicated circuit, if needed.
- Additional refrigerant charge, if the length requires it.
- Installation warranty (separate from the manufacturer's warranty).

Frequently asked questions
Should I include the price of the unit?
If you sell it, list it separately under Equipment so the client can compare. If the client buys it, say so in the notes.
How do I quote extra line set?
State how much line set the standard installation includes and a price per additional foot or meter. That way the estimate stays valid even if the distance changes a little.
