Air conditioner installation cost factors:

The AC system's size

If you're considering a new AC, sizing the system correctly is one of the biggest challenges of the job. Cooper makes sure we get it right by performing a load calculation during your free estimate. What does a perfectly-sized AC get you? Lower energy bills, a longer-lasting system, and better cooling coverage across the home. AC size does impact system cost, but because AC size and home size are correlated to one another, you wouldn't want to try to save money getting a system that's smaller than your home's needs!

The system's efficiency levels

Every air conditioner is rated on its efficiency by what's known as a SEER score. Systems with higher SEER ratings cool your home more efficiently. They also cost more to buy. The trick is to find a system that's both efficient and within your budget. We can help with that.

Ductwork modifications

Even the most efficient AC system won't last long without reliable ductwork. That's why we always say that additions and repairs to ductwork–if necessary–are well worth the investment at the time of the installation.
