Anatomy of a $5,000 Quote
Homeowners are often shocked when they see a unit online for $1,500 but get a quote for $5,000. Is the contractor ripping you off? Not necessarily. Here is where the money goes in a professional installation:
The Unit
Wholesale cost to pro
Labor (2 Techs)
6-8 Hours @ $150/hr

Overhead & Profit
Insurance, Trucks, Warranty
The “Labor Tax”
Notice that over 50% of the quote is Labor and Overhead. This is the “Gap” that DIY products exploit.

Frequently Asked Cost Questions
Why are mini splits so expensive to install?
It is labor-intensive. A technician must drill through walls, run copper lines, perform a nitrogen pressure test, and vacuum the system. It also requires a licensed electrician for the power.
Can I install it myself to save money?
Yes, but only with specific brands like MrCool DIY. Standard brands (Mitsubishi, Fujitsu) require specialized HVAC tools.
Does Costco have cheaper installation?
Costco partners with local Lennox dealers. While you get a 10-15% “Shop Card” rebate, the upfront quote is often higher than local independent contractors.
Stop Guessing. Start Saving.
The biggest mistake is buying the wrong size. An oversized unit costs more upfront AND wastes electricity.
