The Cost to Install an HVAC System with Ductwork: What You Should Know

The costs of installing an HVAC system with ductwork can vary greatly depending on the type of system you choose, the size of your home, and other factors. The installation cost is just one part of the final cost to upgrade your home’s heating and cooling. There are a number of additional expenses that you may not have considered. This article will take you through the key considerations when estimating how much it will cost to install an HVAC system with ductwork in your home. Read on to learn more about what these systems involve, how they differ from standard centralized systems, and what expenses you might not anticipate when getting quotes for this project.

What is HVAC with Ductwork?

HVAC stands for “heating, ventilation, and air conditioning”. An HVAC system with ductwork is a central heating and cooling system where the air is blown through ductwork throughout your home. This type of system is commonly used in new construction. Centralized systems are also referred to as “forced air” systems. A ductless mini-split system is an alternative to a central system. This system uses ducts, but they are much smaller than the ducts used in a central system. Mini-splits can be installed almost anywhere in a home and are used in renovations and additions where the ductwork has already been installed. Ductwork is the collection of pipes and wires that delivers the conditioned air throughout your home. It is typically installed inside the walls of your home, although some systems use ducts outside the walls. It is important to factor in the cost of the ductwork when estimating the overall cost of installing an HVAC system with ductwork.

Estimating the cost to install an HVAC system with ductwork

The first step in estimating the cost of an HVAC system with ductwork is to determine the size of system you will need for your home. You can find charts online or in the manufacturer’s installation manual that will tell you the recommended BTU (British Thermal Unit) output for your home based on the climate in your area and the square footage of your home. This number is what you will use to determine the size system you will need. The next step is to find contractors to provide you with quotes for the installation. You can find contractors online or through word of mouth. Make sure that the contractors are licensed and insured. Also, ask the contractors if they have been in business for a while and what the experience of their team members is. The more experienced the contractors are, the more likely they will be able to give you a more accurate estimate.

Standard Centralized HVAC Installation Costs

Expect to pay between $8,500 and $14,000 to install a standard centralized HVAC system in your home. This includes the cost of the HVAC system itself, ductwork, installation, permits, and other related expenses. Centralized systems are a one-time investment, whereas a ductless mini-split system is installed on each level of the home. The price of a standard centralized system installation is comparable to a ductless mini-split system installation, but there are a couple of key differences between the two systems that can impact installation costs. The size of the ductwork needed for a centralized system is often much larger than the ductwork needed for a mini-split system. Centralized systems often need ducts that are several feet in diameter.

Ductless Mini-Split Installation Costs

Expect to pay around $5,000 to $8,000 to install a ductless mini-split system in your home. This includes the cost of the mini-split system itself, ductwork, installation, permits, and other related expenses. Because mini-split systems are typically installed in one part of the home, you don’t need to worry about installing ductwork throughout your entire home. Mini-split systems are installed on each level of the home, but the ductwork is much smaller and requires less materials than a centralized system. The price for this type of installation is comparable to that of a standard centralized system installation, but the difference in the size of the ductwork needed may impact the total cost of the project.

Important Things to Keep in Mind When Estimating Install Costs for HVAC Systems with Ductwork

Keep in mind that the estimates you receive may vary depending on several factors. The contractor you hire will likely want to walk through your home to assess the best way to install the ductwork. This can add a couple of hours to the job. Contractors may also want to run some tests to ensure that the ducts are installed correctly. This testing can add additional costs to the project. Finally, there may be some additional construction costs associated with the installation if your home needs repairs or additional supports to install the ductwork. Overall, keep these things in mind to make sure that you receive accurate quotes and understand what is factored into each estimate you receive.


There are a few factors that can affect the costs of installing an HVAC system with ductwork. The size of the system you choose will impact installation costs. Standard centralized systems require much larger ducts than ductless mini-split systems. You should also consider the costs of any repairs or additions to your house that are required for the installation. Finally, the contractors you hire can have a big impact on the final costs. Make sure that you choose contractors with experience installing systems in your area and who offer a warranty on their work.
