HVAC Replacement Cost

How much does it cost to replace a central air conditioning unit?

Most likely you started wondering, how much does  an ac compressor replacement cost? And now you are wondering how about the cost for an air conditioning installation? 

 Installation prices can vary depending on many things, the national average cost is between $4,800 – $10,000 for a mid-efficiency system.

So what makes the price vary so much? Things like energy source, mid-efficiency and high-efficiency, warranties and quality of the installation are some of the things to take in count. The some time to read our system guid to find our what option fits you budget and needs.

  • Are you replacing your current system to upgrade or because it no longer works?
  • What it due to a dirty blower wheel?
  • Dirty Evaporator Coil?
  • What are some things you would like to change from your current system?
  • Do you have cold/hot spots throughout the house?
  • Are you looking to save energy?
  • How is the air quality in your home? 
  • How is the humidity?
  • Is the air too dry in the winter?
  • Did your current system lost efficiency due to dust en air leaks?

Make a list some of some key points that are important to you and add them as part of your interview with are experts. A lot of times you will hear that it’s not always about the box, it also has to do with how you install it.

Sometimes higher end systems cost more money upfront, but in return they will save you more money also in the long term, as opposed to investing in a basic system that will save you money upfront, and that’s it. 


  • How is the condition of your hvac ductwork?
  • How is the ductwork insulation?
  • Are they sealed from end to end?
  • What is the R value?
  • Do you have enough ductwork? Older systems were sized for 350 cfms/ton of air, newer system push 400 cfms/ton. We have seen some drastic examples that compare to putting a Ferrari motor on a Honda Civic.
  • What type of filter do you currently have?

The thermostat

A digital thermostat is a must, they are more reliable and accurate, nowadays smart thermostats are a trend and to some people, a tool. They are programmable, you can control them through phone apps and some also learn as you adjust them, so they eventually program themselves. Smart thermostats can read percentage of humidity in your home besides temperature, this is an option that can definitely increase the comfort in your home tremendously. They can be paired with other smart home devices, light switches, cameras, smoke detectors and much more.


Indoor heating system

Furnace or Air Handler, this depends if your heater uses gas or electricity.

Gas furnaces

Years ago, furnaces used to be single speed systems only, meaning that they are either on or off. They were commonly known as 80% furnaces, meaning that about 80% of the fuel was used to heat your home, the other 20% was wasted. 

New furnaces have 2 or 3 stages, so your furnace can run at a lower power and fuel consumption and still heat your home while you save money. They also have different options regarding the blower motor, which is the motor that moves the air in your home. Motors can be single-speed, variable speed, or ECM motors. To sum all of this up, you should consider 80%, 90%, and 95% furnaces when looking to upgrade.

Air Handlers

Air handlers are used in homes with no gas or where a customer prefers to use electric heat or a heat pump. Air handlers come with single-speed blower motors, variable speed, and ECM motors. An electric heater is added to air handlers which can be used as the primary heating source or as a backup heater if the air handler is paired with a heat pump. The Air handler plus Heat pump combination is an option to consider when you want to save money while heating your home. As an example: a 1500sqft home can use approximately 9.68 kilowatts per hour; a heat pump for the same house uses an average of 3.2 kilowatts.

The Condenser or Heat pump

Most of the time, the most common term you will hear when looking for a new condenser is SEER. Condensers go from 14 up to 20 plus SEER in energy efficiency; you will also hear about watt consumption and stages. To simplify this, when replacing your condenser, you should look into single stage, 2 stage, and Variable capacity systems when you are considering comfort and energy savings as an end goal.

2 stage condensers or heat pumps are designed to run primarily in low stage; this uses less energy and enables the air conditioner system to run longer, as it dehumidifies and cools your home better. 

Variable capacity systems have more than 2 speeds or stages, allowing them to run longer, sometimes up to a 30% capacity. Like 2 stage systems, the purpose of lower speeds is to save energy, lower humidity, and cool a home with more even temperatures. Variable speed condensers use DC high energy-efficient motors controlled by what the smart thermostat reads in your home. These systems come equipped with indoor and outdoor sensors that report temperatures, pressures, energy consumption, and much more, allowing them to adjust as needed in order to provide comfort and energy savings.
