What Is the Average Cost to Have Someone Install an AC Unit?
If you’re a homeowner in San Ramon, CA, and considering air conditioner installation, one of the first questions you’ll likely ask is: How much does it cost to have someone install an AC unit?
The answer depends on several factors, but generally, homeowners in California can expect to pay between $6,000 and $12,000 for a full AC installation, including equipment and labor. However, the total cost can vary significantly depending on your home’s size, the type of system you choose, the complexity of the installation, and the energy efficiency rating of the unit.
Let’s take a deeper look at what drives these costs and what you should expect when hiring a professional HVAC installer.
Key Factors That Influence AC Installation Costs
Type of Air Conditioning Unit
The kind of air conditioning unit you select is one of the biggest factors in determining cost. Here are some of the most common options:
- Central Air Conditioning Systems are ideal for whole-home cooling. They’re the most common type installed in San Ramon homes and tend to fall on the higher end of the price range due to the need for ductwork and more extensive labor.
- Ductless Mini-Split Systems are more affordable for smaller homes or spaces without existing ducts. These systems allow for zone cooling and can be more cost-effective depending on your needs.
- Heat Pumps, which offer both heating and cooling, are popular in California because of their energy efficiency and year-round use. They tend to have a higher upfront cost but offer excellent long-term savings.
Each system varies in terms of equipment cost, installation time, and long-term energy efficiency, which can all affect the final price of your air conditioner installation.
Size of the System (Tonnage)
The size of your AC unit is measured in tons, which refers to its cooling capacity. Larger homes require more powerful units, which come with higher costs. A professional HVAC contractor will perform a load calculation to determine the correct size for your home.
- For example, a 2-ton unit may be sufficient for a 1,200 sq ft home, while a 5-ton unit may be required for a 2,500+ sq ft property.
Installing a system that’s too small or too large can lead to poor performance, energy waste, and premature wear, so proper sizing is crucial for both comfort and cost efficiency.
Energy Efficiency (SEER Rating)
In California, SEER (Seasonal Energy Efficiency Ratio) requirements are higher than in many other states. Higher SEER ratings mean greater energy efficiency—but also a higher upfront cost.
- 14 to 16 SEER units are generally more affordable and meet minimum efficiency standards.
- 17 to 21+ SEER units offer better long-term energy savings and may qualify for utility rebates or tax incentives.
While high-efficiency units come with a larger price tag, they can significantly lower monthly energy bills and reduce your carbon footprint over time.
Ductwork and Electrical Upgrades
If you’re replacing a home AC unit, your existing ductwork may be reusable—but if it’s outdated, leaky, or improperly sized, replacement or repair will add to the cost.
Likewise, your home’s electrical panel may need upgrading to support the new system, especially if it’s older. These upgrades ensure the safe and efficient operation of your air conditioning unit and are common in full system installations.
Labor and Installation Complexity
Labor typically makes up about 30% to 50% of your air conditioner installation cost. More complex jobs—such as installing ductwork in an older home, placing a unit in a difficult-to-reach attic, or removing an existing system—will take longer and cost more.
That’s why it’s essential to work with experienced HVAC contractors near me who can evaluate the job properly and avoid costly mistakes.
What’s Included in the Cost?
A full AC installation typically includes:
- New air conditioning unit
- Thermostat installation
- Labor and tools
- Permit and inspection fees
- Removal and disposal of the old unit (if replacing)
- Ductwork modification or installation (if needed)
- Electrical and refrigerant connections
- System testing and calibration
When you choose a licensed HVAC installer, they’ll handle everything from system sizing to post-installation walkthroughs, ensuring you get a system that works efficiently and reliably.
Is It Worth the Investment?
Absolutely. A new air conditioning unit can significantly improve your home comfort, reduce your utility bills, and add resale value. Whether you’re building a new home, upgrading an older unit, or replacing your AC unit after a breakdown, professional installation is essential.

How Much Does It Cost to Put AC in a 2,000 Sq Ft House?
If you’re a homeowner in San Ramon, CA, with a 2,000 square foot home and you’re thinking about installing air conditioning, you’re likely wondering: “How much will it cost to install AC in my house?”
On average, the cost to install air conditioning in a 2,000 sq ft home ranges between $8,000 and $15,000, depending on the system type, energy efficiency, installation complexity, and whether ductwork already exists. While this is a broad range, understanding what drives the cost can help you make a smart investment in your home’s comfort and efficiency.
Let’s break down the key factors that influence the cost of air conditioner installation for a house this size.
Type of Air Conditioning Unit
One of the most significant cost drivers is the type of air conditioning unit you choose. For a 2,000 square foot home, you’ll typically need a system with a cooling capacity between 3.5 and 5 tons.
Central Air Conditioning
- Cost Range: $8,000 – $13,000
- This is the most common choice for whole-home cooling. It requires ductwork and is typically paired with a furnace in a split system.
- If your home already has ducts in good condition, this is often the most cost-effective option for a large home.
Ductless Mini-Split System
- Cost Range: $10,000 – $15,000 (for multiple indoor zones)
- Ideal for homes without existing ductwork or for homeowners who want zoned temperature control.
- Installation is more flexible, but multiple indoor units are required to cool a full 2,000 sq ft space effectively.
Heat Pump System
- Cost Range: $11,000 – $15,000
- Offers both heating and cooling, making it an energy-efficient choice for year-round comfort.
- Often eligible for rebates and tax credits due to energy savings.
Whether you’re replacing a home AC unit or starting from scratch, your HVAC contractor will recommend the right system for your home’s size and layout.
Energy Efficiency and SEER Rating
In California, energy efficiency plays a huge role in system pricing. All systems are rated using the Seasonal Energy Efficiency Ratio (SEER). Higher SEER ratings mean lower utility bills, but higher upfront costs.
- 14–16 SEER units: Standard efficiency, more affordable upfront
- 17–21+ SEER units: Premium efficiency, higher initial investment but long-term savings
For a 2,000 sq ft home, choosing a higher-SEER unit might raise your initial installation cost by $1,000 to $2,500, but it can save you hundreds per year in energy bills.
Ductwork Condition and Configuration
Do you already have ductwork? Is it in good shape? This can significantly impact the final cost of your AC installation.
- New Ductwork Installation: $2,000 – $5,000
- Minor Duct Repairs or Sealing: $500 – $1,500
If your current ductwork is leaky, poorly insulated, or improperly sized, your HVAC contractor may recommend replacing or repairing it to ensure your new air conditioning unit performs efficiently.
Labor and Installation Complexity
Labor typically accounts for 30% to 50% of your total installation cost. Factors that affect labor pricing include:
- Accessibility of installation area (attic, crawlspace, etc.)
- Electrical upgrades required
- Permit processing and inspections
- Removal of old equipment (if replacing AC unit)
Every home is unique, which is why hiring experienced HVAC contractors near me is key to ensuring accurate pricing and proper installation.
Permits and Inspections in California
In San Ramon, and throughout California, you’ll need permits for most air conditioner installations. These ensure compliance with Title 24 energy efficiency codes and safety regulations.
- Permit Costs: Typically range from $250 to $500 depending on the project scope.
- At Refreshed Heating & Cooling, we handle all permitting and inspections so you don’t have to worry about the paperwork.
The Value of Investing in Quality Installation
While the cost to put AC in a 2,000 sq ft home can feel significant, the benefits far outweigh the expense. A properly installed air conditioning unit will:
- Deliver consistent, comfortable indoor temperatures
- Reduce energy usage and monthly utility bills
- Improve indoor air quality and humidity control
- Increase the resale value of your home
If you’re replacing an air conditioner that’s over 10–15 years old, you’ll also benefit from improved efficiency, quieter operation, and fewer repairs.
Do I Need a Permit to Install an Air Conditioner in California?
Yes, in most California cities, including San Ramon, a permit is required to install or replace an air conditioner. This ensures the system complies with energy efficiency codes and safety standards. Working with a licensed HVAC contractor like Refreshed Heating & Cooling ensures this process is handled properly and legally.
Permits Typically Cover:
- Mechanical installation
- Electrical connections
- Structural modifications (if any)
- Title 24 energy compliance
We take care of the entire permitting process for you—filing, scheduling inspections, and ensuring your system is fully code-compliant.
Is It Time to Replace Your Existing Air Conditioner?

- Your unit is 10–15 years old or older
- Frequent breakdowns or costly repairs
- Higher energy bills
- Uneven cooling or poor airflow
- Loud noises or unpleasant odors
