Is It Required to Install a New HVAC System for a Home Addition?

Whether you’re adding a second family room, a guest suite or growing the kitchen, having more square footage in your home is sure to be convenient. Just keep in mind you need to consider the heating and cooling necessities of the new space. One of those points should involve whether you should upgrade your HVAC system for a home addition in Nashville. Our guide will help you as you begin the process.

Option 1: No Upgrade Needed

If the home addition includes expanding a room instead of building entirely new rooms, you may not need to improve the HVAC system at all. This is often the instance if your heating and cooling equipment was too large when they were installed. Request a load calculation from an Expert technician, like one from Donelson Air Service Experts by calling 615-953-9885. This will decide if your existing HVAC equipment can take on the upgrades you’ve made to your home.

Option 2: Install a New HVAC System

Another solution for delivering heat and air conditioning into your home addition is to extend the ductwork from your present forced-air equipment. If you have radiators or baseboard heating, you can add hot water piping to the new area.

Bear in mind that, along with ductwork or water piping, you might also have to add HVAC equipment to take care of the increased load. The following increase in electricity use may even need a new electrical panel. If your heating and cooling system needs to be replaced soon, this could be perfectly acceptable.

Option 3: Add a Ductless Mini-Split

Rather than installing a new unit to manage the added space, you can put in an independent one. Ductless mini-splits are great for this. They have two parts. There’s a condensing unit that sits on cement outdoors, akin to an air conditioner. Then there’s the compact indoor blower that is placed to the ceiling or wall.

Like a central heat pump, mini-split HVAC systems provide both heating and cooling for year-round comfort from one system.

Since it has a wall- or ceiling-mounted air handler, ductwork isn’t necessary. You can even link up to four indoor blowers with one outdoor unit for zoned heating and cooling in distinct parts of your residence. A ductless mini-split might be the right HVAC option for your home addition if:

  • Your current system can’t absorb the extra room, and you’re not prepared to replace it all right away.
  • The old and new additions have different heating and cooling needs.
  • You would like to add air conditioning to your house without putting in or adding on to the ductwork.
