Do I Need to Get a New HVAC System for a Home Addition?

Whether you’re building a second family room, a guest suite or enlarging the kitchen, having extra square footage in your home is sure to prove useful. Just remember to consider the heating and cooling requirements of the new space. One of those considerations should include whether you should upgrade your HVAC system for a home addition in North America. Our instructions will help you as you take the first step in the process.

Option 1: No Upgrade Needed

If the home addition calls for enlarging a space instead of building completely new rooms, you may not need to upgrade the HVAC system at all. This is usually the instance if your heating and cooling equipment was oversized to begin with. Book a load calculation from a professional technician, like one from Service Experts Heating & Air Conditioning by calling 866-397-3787. This will determine if your present HVAC equipment can manage the modifications you’ve made to your home.

Option 2: Upgrade Your HVAC System

Another idea for getting heat and air conditioning into your home addition is to extend the ductwork from your current forced-air unit. If you use radiators or baseboard heating, you can extend hot water piping to the new room.

Bear in mind that, adding ductwork or water piping, you could also have to install HVAC equipment to manage the bigger load. The resulting increase in electricity usage might even call for a new electrical panel. If your heating and cooling system needs to be replaced soon, this might be a good solution.

Option 3: Get a Ductless Mini-Split

Rather than getting a new system to manage the extra square footage, you can get an independent one. Ductless mini-splits are perfect for this. They consist of two parts. There’s a condensing component that is installed on the ground outside, much like an air conditioner. Then there’s the space-saving indoor blower that is installed to the ceiling or wall.

Similar to a central heat pump, mini-split HVAC systems provide both heating and cooling for continuous comfort from a sole piece of equipment.

Since it uses a wall- or ceiling-mounted air handler, you don’t need ductwork. You can even add up to four indoor blowers with one outdoor unit for zoned heating and cooling in distinct spaces in your home. A ductless mini-split might be the ideal HVAC solution for your home addition if:

  • Your present system can’t handle the added room, and you’re not ready to replace every part right away.
  • The old and expanded rooms have differing heating and cooling needs.
  • You want to add air conditioning to your home without installing or adding on to the ductwork.
