Are you tired of your central HVAC system not cooling certain rooms effectively? Or maybe you're adding an addition to your home and need an additional cooling solution? In either case, a mini split air conditioner might be the perfect solution for you. But how much does it cost to install one? Let's find out!

Mini Split AC Unit Installation Costs

When it comes to mini split ACs and heat pumps, there are two main types: single zone and multizone systems. Single zone systems are typically used when the central HVAC system doesn't cool certain rooms effectively. On the other hand, multizone systems are commonly installed in new constructions or when replacing a central HVAC system.

One of the major advantages of a ductless mini split system is that it eliminates the cost of ductwork and the potential issues of air loss in leaky ducts. However, the total installed cost will depend on several factors. On average, the installed cost of a single zone mini split AC/heat pump unit ranges from around $6,670. This includes a unit with 12,000 to 36,000 BTU and minimal complications.

For a 3-5 zone system, the average installed cost is between $10,650 and $19,450. The size and type of indoor units play a significant role in determining the cost. Wall-mounted units are the most affordable, while ceiling-mounted units tend to cost the most.

The installed cost of a single zone system usually includes the complete MiniSplit AC unit (indoor air handler and outside condensing unit), refrigerant lineset and wiring, drain, electrical work, mounting hardware, installation supplies, and cleanup. Additionally, the HVAC company will handle permits and inspections.

Overview of Ductless Mini Split Air Conditioner Systems

Most mini split AC-only systems are designed to cool smaller areas of your home or office. However, if you're looking for a heat pump system, you can opt for a multi-zone system with a single outdoor unit and multiple indoor units.

It's worth considering buying a heat pump package with outdoor and indoor units instead of purchasing separate components. This way, you'll have heat included as well. If you're considering multi-zoned units, it's also a good time to compare prices and consider a complete central AC system or a geothermal heat pump system for maximum efficiency.

Ductless mini split air conditioner packages typically include the outdoor condensing unit, indoor evaporator unit, thermostat remote control or wall control. Installation supplies such as refrigerant line set, drain, wiring, and electrical connection are sold separately.

Mini Split AC Cost Factors

Several factors will determine the total cost of your mini split air conditioner installation:

  • Outdoor Unit Size: Ductless AC condensing units range from 9,000 to 42,000 BTUs.
  • Number of Indoor Units: While single-zone systems are common, multizone systems can be individually configured. Each additional indoor unit increases material and labor costs.
  • Type of Indoor Unit: Your options include wall-mounted, ceiling-suspended, ducted, and ceiling cassette units. Costs vary based on the type of unit.
  • Efficiency: The SEER rating determines the efficiency of the system. Higher efficiency units usually come at a higher price.
  • Brand Quality: Premium brands like Samsung, Mitsubishi, Friedrich, Fujitsu, Toshiba/Carrier, Daikin, Trane, LG, and Panasonic tend to cost more than standard-quality brands.
  • Removal and Disposal of Old Equipment: Typically included in estimates, but you can save money if you handle this part yourself.
  • Cost of Living: Prices may vary based on the location.

Additionally, factors such as the location of the installation and the installation difficulty can affect the overall cost.

Cost of AC Equipment and Installation Supplies

As you shop for a mini split air conditioner, you'll come across various costs:

  • Equipment: The retail costs of indoor and outdoor units and controls vary based on the size, quality, and features.
  • Installation Supplies: These include accessories like wiring whip, drain, shut-off, pad for ground installation, rack and hardware for wall installation, and electrical wire or a new circuit and breaker.

Permits, Inspection, and Unit Installation Costs

When it comes to permits and inspection, you can expect to pay around $50 to $200 for an electrical permit. As for labor costs, the installation of a single-zone air conditioner with one outdoor unit and one indoor unit ranges from $1,050 to $2,300. For each additional indoor unit, the installation cost is between $350 and $800.

Factors that can affect the installation cost include the difficulty of the installation, such as working in challenging locations or during busy seasons when demand is high.

DIY or Hire a Pro?

Finally, you might be wondering if you can install the mini split air conditioner yourself. While some brands offer DIY-ready units, most systems require installation by a certified contractor. Handling the installation yourself can void the manufacturer warranty.

However, during the contractors' slow season, you might find a certified installer who is willing to work with you on a DIY-prohibited system. In such cases, you can handle everything that doesn't require a license, and the installer can connect and charge the system.

In conclusion, installing a mini split air conditioner can vary in cost based on several factors. It's important to consider the size, type, and efficiency of the system, as well as the brand and additional installation supplies. Whether you choose to hire a professional or opt for a DIY-ready system, make sure to weigh the costs and benefits before making a decision.

Remember, staying cool and comfortable during the summers is worth the investment!
