As summer temperatures rise across the Denver metropolitan area, more homeowners in Littleton are turning to professional air conditioning installation services to stay cool and comfortable. If you’re considering a new AC installation, it’s important to understand the average HVAC installation costs, what impacts pricing, and what kind of system best fits your home, space, and budget.
Whether you’re upgrading your outdated central air conditioning or looking into a modern mini split installation, this guide will help you estimate your expenses and know what to expect from reputable HVAC contractors like Roots HVAC.
Average Cost of AC Installation in Littleton, CO
For homeowners in Littleton, the average cost for air conditioner installation typically ranges from $4,700 to $6,500. However, several factors can push that number higher or lower.
Basic Central AC Installation
- Standard single-stage unit: $6,500–$9,200
- Central air conditioner installation for smaller homes or spaces with existing ductwork falls here.
High-Efficiency & Multi-Stage Systems
- Two-stage or variable-speed units: $9,500–$12,200+
- These units come with higher SEER (Seasonal Energy Efficiency Ratio) ratings, improving your home’s energy efficiency and indoor air quality, while reducing long-term electricity usage.
Full HVAC Replacement
- For both a furnace and AC installation, expect between $9,800 and $13,400. Upgrading both at once often saves on labor and can increase your home’s total efficiency.
Mini Split & Ductless Systems
- 1-zone mini split AC installation: $3,600–$6,500
- Multi-zone mini splits: $8,800–$26,000+
- Great for homes without existing central heating or for room-specific climate control.
Factors That Affect the Price
-
Size of Your Home
Larger homes require more powerful cooling systems, which impacts installation costs and system size (measured in square feet and BTUs).
-
Ductwork Modifications
If your current ductwork is outdated, leaky, or missing entirely, this will increase the price. In some cases, ductless air conditioner installation like a mini split may be more practical.
-
Efficiency Ratings
A higher SEER rating means better performance and energy savings, but with a higher upfront expense. ENERGY STAR® certified units offer great long-term value.
-
Labor & Permits
Skilled HVAC technicians, local permit requirements, and additional services like electrical upgrades or plumbing adjustments may impact your final invoice.
-
Extra Features
Add-ons such as a humidifier, dehumidifier, smart thermostat, or air filter system to boost your home’s indoor air quality will increase costs but add year-round comfort.
How to Save on AC Installation
- Check for rebates from local utility companies or tax credits for installing high-efficiency equipment.
- Opt for an extended warranty or maintenance plan to protect your investment.
- Ask about financing options to spread out the cost over time.
- Partner with a reputable installation company like Roots HVAC that offers transparent pricing, customer satisfaction guarantees, and high-quality repair services if needed.

For central AC installation, most jobs are completed in 1–2 days. Mini split air conditioner installation or projects involving ductwork or electrical upgrades may take longer. - Should I install a mini split or a central air system?
