Understanding the factors that affect the cost of your new mini split AC unit

1. Capacity & size

The size of the space you intend to cool or heat will determine the size and capacity of the mini-split system you need, measured in British Thermal Units (BTUs). A system with a higher BTU capacity will usually cost more than one with a lower capacity.

2. Features & functionality

Additional features like programmable thermostats, remote control options, and heating capabilities can also affect the unit’s price. Higher-end models may offer advanced filtration systems, humidity control, or smart home compatibility, raising the cost but providing added convenience and functionality.

3. Brand & quality

The brand and model of the mini-split can significantly affect the price. Premium brands often come with advanced features, higher efficiency ratings, and longer warranties, but they also come with a higher price tag.

4. Number of zones

The number of indoor units or “zones” you want to cool or heat will influence the overall cost. More zones mean more indoor and outdoor units, increasing the price accordingly.

Frequently asked questions about Mini Split AC installation in Phoenix

The cooler months (December to March) are generally the best time to install a new AC unit in Phoenix. In winter, air conditioning contractors in Phoenix experience lower demand. This may result in lower ac replacement costs.

Indeed, the majority of AC units are accompanied by a manufacturer's warranty. Generally, you'll encounter two kinds of warranties: one from the manufacturer that covers component defects, and another for labor that ensures quality workmanship during installation. Combined, these warranties aim to provide comprehensive protection for your new ac unit, covering everything from parts to the installation process.

The duration required to set up an AC unit can differ due to a variety of elements such as the model of the unit, the nature of the installation, the size of your home, and the unit's location. Generally speaking, an air conditioner installation can be completed within a 4 to 8-hour timeframe. However, some projects may necessitate additional time based on their complexity.

A new air conditioning installation in Phoenix, offers many benefits:

  • improved energy efficiency
  • lower electricity bills
  • enhanced comfort
  • better indoor air quality
  • reduced environmental impact

Newer models often incorporate advanced features and technologies. This comes with more precise and advanced temperature control.

Yes, we offer AC financing in Phoenix for our customers. Apply for AC financing in 3 simple steps and receive flexible payment terms with our financing partner Synchrony.

Selecting the appropriate AC unit for your home is crucial for maximizing your investment. Various elements come into play when making your choice, such as your home's square footage, the quality of insulation, your local climate, and the state of your ductwork. To identify the ideal size and model for your specific needs, you can either consult an HVAC expert or utilize online tools and resources.

SEER, or Seasonal Energy Efficiency Ratio (occasionally referred to as Seasonal Energy Efficiency Rating), quantifies an air conditioner's efficiency by evaluating its cooling output relative to its energy consumption. The higher the SEER number, the greater the efficiency—meaning the unit cools your home effectively while utilizing less energy.

Finding 'the best AC installation service' in Phoenix is more granular than one might think. The big and established companies oftentimes come with compromises due to their size.


The first step to to find a reputable and professional AC contractor in Phoenix: Start by asking for recommendations from friends, family, or colleagues. Ask the ones who have recently purchased or installed a new AC unit.

Additionally, online platforms can provide valuable insights, too. Scan the contractors' reputation and customer reviews. Here re some platforms you could use for your research:

  • Google Maps
  • Yelp
  • Angies List
  • Better Business Bureau

Narrow down your options to two or three contractors.


Request detailed estimates from each to compare their offerings. Avoid estimates and quotes over the phone. There is no such thing as a one-size-fits-all solution to a new ac unit. A reliable ac contractor will come out and assess your specific needs. In this assessment they should ask you questions like:

  • How old is your current system?
  • How long are you planning to stay in your home? (Gives direction which system/investment makes sense for the customer)
  • Are there any warm spots in the home?
  • Is power usage a concern to you? (Taking possible solar power into consideration)

These questions show their genuine interest in finding the best system for you.Rather than trying to make the most money off of you.
