How Much Does A New AC Unit Cost with Installation?

May 26, 2025

If you’re sweating buckets in your living room and Googling “How long does AC installation take?” – you’re not alone. It’s one of the most common questions we get at Done Deal A/C & Heating Katy, and for good reason. You want comfort, and you want it fast. But just how fast can that new air conditioner be up and running?

Let’s break it down step-by-step and give you the full picture.

Understanding the AC Installation Process

Pre-Installation Assessment

Before any actual work begins, a technician will swing by to evaluate your home. They’ll look at your old unit (if you have one), check ductwork, take measurements, and recommend the best system for your needs.

Choosing the Right AC Unit

You don’t want a system that’s too small or too powerful. A quick chat with a pro can help you select a model that’s just right in terms of cooling power, energy efficiency, and size.

Average Time Required for AC Installation

Typical Residential Installations

For most single-family homes, installation takes between 4 to 8 hours. That includes removing the old unit, installing the new one, hooking up electrical and ductwork, and testing the system.

Commercial or Complex Installations

For larger systems or tricky layouts (think multi-zone systems or tight crawlspaces), installation could stretch into 1 to 2 days.

Factors That Can Affect Installation Time

Type and Size of the AC System

Installing a ductless mini-split? That could be faster than a central air system. But if you’re upgrading to a more complex system, expect a longer timeline.

Accessibility of the Installation Site

If your unit is going on the roof or in a cramped attic, techs will need more time—and possibly special equipment.

Old System Removal

If your old system is rusted, leaking, or improperly installed, it could slow things down. Sometimes, surprises are hidden under that dusty old condenser!

Permit Approvals and Inspections

In Katy, Texas, local permits might be required. Some jobs need to be inspected before and after installation, depending on the municipality.

Setting Up the New System

Mounting the indoor and outdoor units and securing them properly.

Electrical and Ductwork Connection
