For most residential homes, the total cost to install central air with no existing ductwork usually falls between Rs. 2 lakh to Rs. 7 lakh or more, depending on the house size and tonnage.

What is the Cost to Install Central Air Without Existing Ductwork?

  1. The central AC unit itself can cost around Rs. 50,000 to Rs. 1,50,000+, based on capacity and brand. Large systems (like 11-ton) can cost Rs. 2.3 to Rs. 2.8 lakh for the unit alone.

  2. Duct fabrication and installation is the biggest expense. Dealers may charge Rs. 30,000 to Rs. 45,000+ for a full setup. Labour charge only may range from Rs. 5,000 to Rs. 20,000.

  3. Add Materials and Extras: Copper piping and wiring may cost Rs. 200 to Rs. 400 per foot. Extras include: Core cutting: Rs. 1,500, ODU bracket: Rs. 750 to Rs. 950, Nitrogen testing: Rs. 750 to Rs. 1,100 per unit

Always take 2 to 3 quotes, because layout complexity changes pricing a lot.

We installed a Blue Star central air conditioning at our home and the installation cost us Rs. 1600. But it actually depends on a number of factors like the brand, capacity, location of installation, etc. According to the technician we hired, an average cost to install central air without existing ductwork starts from Rs. 800. 

What is the Cost to Install Central Air with No Existing Ductwork?

A central AC installation will require a different set of considerations, so the pricing usually varies as compared to split AC and window AC installation. Apart from the brand and capacity, I learned there are many other factors that affect the overall cost of installing a central AC. 

The professional mentioned that in India, the range is typically between Rs. 800 to Rs. 5000 or more, depending on these factors. Here are a few more things I learned about the cost of installing central AC.

  1. Sometimes, there are additional charges for extra materials, complicated installation, or any electrical work that may be required.

  2. The cost also varies depending on the service provider, brand, and location.

  3. It’s important to choose the right location for your AC to ensure better airflow and performance. 

That’s all I know about the pricing for central air conditioning. I hope this gives you a fair idea. If you aren’t sure about the cost, contact a professional AC technician who can give you clear pricing details.
