Does a Home Addition Call for Upgrading My HVAC System?

Whether you’re building a second family room, a guest space or enlarging the kitchen, having additional square footage in your house is sure to be convenient. Just don’t forget to think about the heating and cooling necessities of the new space. One of those points should include whether you should upgrade your HVAC system for a home addition in Knoxville. Our instructions will help you as you take the first step in the process.

Option 1: No Upgrade Necessary

If the home addition includes growing an area rather than putting on entirely new rooms, you may not need to improve the HVAC system at all. This is usually the case if your heating and cooling equipment was oversized originally. Request a load calculation from an Expert technician, for example one from R & M Climate Control Service Experts by calling 865-229-6176. This will affect if your existing HVAC system can handle the changes you’ve made to your residence.

Option 2: HVAC System Upgrade

Another solution for getting heat and air conditioning into your home addition is to lengthen the ductwork from your present forced-air system. If you rely on radiators or baseboard heating, you can add hot water piping to the new room.

Bear in mind that, in addition to ductwork or water piping, you might also have to add HVAC equipment to handle the bigger load. The following increase in electricity usage may even require an enhanced electrical panel. If your heating and cooling system needs to be replaced soon, this may be a good solution.

Option 3: Get a Ductless Mini-Split

Instead of installing a new system to manage the extra area, you can put in a freestanding one. Ductless mini-splits are ideal for this. They consist of two parts. There’s a condensing component that is installed on cement near your home, much like an air conditioner. Then there’s the space-saving indoor blower that mounts to the ceiling or wall.

Akin to a central heat pump, mini-split HVAC systems provide both heating and cooling for year-round comfort from a single setup.

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

  • Your present system can’t absorb the added space, and you’re not ready to replace everything right away.
  • The old and new spaces have varying heating and cooling needs.
  • You want to add air conditioning to your home without putting in or extending the ductwork.
