How Much Does AC Installation Cost in Colorado?

If you're a Colorado homeowner planning for summer, you’ve likely wondered: how much does AC installation cost? For most homes, the average falls between $3,000 and $6,200, but the exact price depends on your system, home size, and installation complexity. An HVAC installation technician can help you estimate costs based on key factors like the unit’s size, its placement, and your current setup.

What Impacts the Cost of AC Installation?

Several variables go into the price of an AC install, including:

  • Home size: Bigger homes need more powerful systems, and sometimes more ductwork.
  • Type of AC system: Central air, ductless mini-splits, and heat pumps all come with different price tags. Consider the actual size of the unit, because larger units will be more expensive. 
  • Energy efficiency: Higher Seasonal Energy Efficiency Rating (SEER) ratings cost more upfront, but they save on energy bills over time.
  • Existing ductwork: If your home does not have ducts, or if they need repairs, costs may increase.
  • Installation complexity: Accessibility, labor hours, layout, and any needed electrical upgrades can raise labor costs.

Comparing System Types

While it’s increasingly less common, some Colorado homes have a gas furnace but no central AC. Fortunately, in these situations, AC can usually be added to your existing system. On the other hand, if your home uses a boiler or lacks ductwork, a ductless mini-split might be the best fit. Most window AC units are DIY-friendly, but for more complicated installations such as through-the-wall units, you can hire a professional to help, often costing between $100 to $300. 

Here’s a quick look at average equipment and installation costs:

  • Central AC: $6,000 - $13,000
  • Mini-split: $7,000 - $22,000
  • Window Unit: $200 - $750

Warranties

Warranties are another cost factor to keep in mind. Most AC systems include one, but coverage varies by brand. Some offer basic protection, while others include extended coverage for an added fee.

A stronger warranty may cost more upfront, but can offer you peace of mind and save you money on future repairs. If you're unsure what's best, your HVAC contractor can help you choose the right fit for your home and budget.

A few extras can affect the total cost of AC installation:

  • Variable speeds (one-stage, two-stage, and variable speeds all have different costs.)
  • Smart thermostats
  • Safety features
  • Weather or hail covers for protection
  • Noise reduction features
  • Local permits and labor rates

Be sure to ask your contractor for a detailed quote that covers these items so there are no surprises later.

Tips for Keeping AC Installation Costs in Check

To keep AC installation costs manageable, look into local rebates or off-season deals, which can lower your overall price. Financing options like payment plans can also help spread out the cost. Be sure to compare quotes and ask questions, but be sure to stick with licensed, insured contractors familiar with Colorado homes. A little planning goes a long way toward getting a reliable system that fits your budget.

Why the Right Technician Matters

Choosing the right HVAC professional is just as important as picking the right AC unit. A rushed or inexperienced install can lead to higher energy bills, frequent repairs, or a shortened system lifespan. It’s worth going with experienced, reputable professionals, even if the cost is initially higher. Paying a bit more for a qualified tech often saves you money in the long run.
