How to Get an Accurate Quote for a New AC in Arizona

The best way to get an accurate quote for new air conditioning is to speak with an HVAC professional. It also helps to know what you want from your system.   

What Affects the New AC Cost in Phoenix, AZ?

When getting a quote for a new air conditioning (AC) system, there are several important factors and features you should think about.

Type of AC System

Consider the type of AC system that suits your needs. Standard options include central air conditioning, ductless mini-split systems, heat pumps and window units. Each AC option has its own set of pros and cons, so choose a product that meets your requirements, budget, and the structure of your home.


Ensure the AC unit’s cooling capacity matches the size of the space you need to cool. An undersized unit won’t effectively cool the area, while an oversized unit may lead to inefficient operation and excessive energy consumption.
  • Calculate the square footage: Measure the length and width of the rooms or spaces you want to cool. Multiply these dimensions to get the square footage. 
  • Consider insulation: Well-insulated rooms generally require less cooling capacity, while poorly insulated areas may need more. Insulation quality affects the heat transfer between the inside and outside of the room.
  • Determine the cooling load: The cooling load is the amount of cooling required to maintain a suitable temperature in the space. Factors such as the number of windows, orientation to sunlight, and the number of occupants contribute to the cooling load. HVAC professionals use Manual J calculations to estimate this load accurately.

Energy Efficiency

Look for an AC unit with a high energy efficiency rating. Energy-efficient models can help you save on electricity bills over the long run. Check for the SEER (Seasonal Energy Efficiency Ratio) rating, with higher ratings indicating better efficiency.

Brand and Quality

Research reputable AC brands that are known for reliability and durability. Look for ratings from reliable sources to assess the quality and performance of the brands you are considering.


Check the warranty details provided with the AC unit. A longer warranty period demonstrates the manufacturer’s confidence in their product. Confirm that you understand the terms and conditions of the warranty, including any maintenance requirements or limitations.

Installation-Related Costs

Ensure you ask about the installation costs included in the quote. Proper installation is crucial for optimal AC performance, so ensure the quote covers professional installation by qualified technicians.

Additional AC Features

Consider any additional features or functionalities that might enhance your comfort or convenience.
  • Programmable thermostat: A programmable thermostat allows you to schedule temperature adjustments throughout the day, optimizing energy usage and maintaining comfort when you’re home while saving energy when you’re away.
  • Smart thermostat integration: Some AC systems are compatible with smart home technology, allowing you to control and monitor your cooling remotely through a smartphone app or voice commands. This feature offers convenience and energy-saving potential.
  • Energy-saving modes: Look for AC units with energy-saving modes or features like “eco” or “sleep” modes. These settings adjust cooling output and fan speeds to conserve energy while still maintaining a comfortable temperature. Although this won’t lower the initial new AC unit cost in Phoenix, AZ, it will help you save money over time.
  • Variable-speed compressor: AC units equipped with variable-speed compressors can adjust their cooling output based on the current cooling needs. This feature provides more precise temperature control, reduces energy consumption, and offers quieter operation.
  • Zoning capabilities: If you have a larger home with multiple zones or varying cooling needs in different areas, consider AC systems with zoning capabilities. Zoning allows you to control the temperature in each zone, optimizing comfort and energy efficiency.

Professional Reputation

Choose a reputable HVAC company with a track record of providing quality service. Ask for references or seek recommendations from friends, family, or online reviews to ensure you select a reliable contractor.
