Does a Home Addition Require Upgrading My HVAC System?

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 guidebook will help you as you begin the process.

Option 1: No Upgrade Necessary

If the home addition includes enlarging an area instead of putting on totally new rooms, you may not need to upgrade the HVAC system at all. This is often 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 system can manage the modifications you’ve made to your residence.

Option 2: Upgrade Your HVAC System

Another solution for delivering 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 area.

Bear in mind that, adding ductwork or water piping, you might 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 requires a replacement soon, this could be a good solution.

Option 3: Get a Ductless Mini-Split

Rather than installing a new system to cover 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 system 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.

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

Since there’s a wall- or ceiling-mounted air handler, no ductwork is required. You can even join up to four indoor air handlers with one outdoor unit for zoned heating and cooling in distinct areas in your home. A ductless mini-split might be the ideal HVAC solution for your home addition if:

  • Your current system can’t handle the additional room, and you’re not able to replace every part today.
  • 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.
