Is It Necessary to Get a New HVAC System for a Home Addition?

Whether you’re building a second family room, a guest suite or expanding the kitchen, having extra square footage in your house is sure to prove useful. Just keep in mind you need to think about the heating and cooling requirements of the new space. One of those factors should include whether you should upgrade your HVAC system for a home addition in Calgary. Our guidebook will help you as you take the first step in the process.

Option 1: No Upgrade Necessary

If the home addition involves enlarging a space instead of building completely new rooms, you may not need to upgrade the HVAC system at all. This is most likely the situation if your heating and cooling equipment was too big to begin with. Get a load calculation from an Expert technician, such as one from A1 Chesney Service Experts by calling 587-315-5271. This will determine if your current HVAC equipment can manage the modifications you’ve made to your residence.

Option 2: Replace Your HVAC System

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

Please note that, along with ductwork or water piping, you may also have to put in HVAC equipment to take care of the bigger load. The subsequent increase in electricity use might even require a new electrical panel. If your heating and cooling system needs to be replaced soon, this might be a good option.

Option 3: Install a Ductless Mini-Split

In place of upgrading your existing unit to cover the additional area, you can install a freestanding one. Ductless mini-splits are ideal for this. They consist of two parts. There’s a condensing unit that is placed on a slab outdoors, akin to an air conditioner. Then there’s the sleek 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 year-round comfort from one solution.

Since it links with a wall- or ceiling-mounted air handler, no ductwork is required. You can even link up to four indoor units with one outdoor unit for zoned heating and cooling in distinct areas in your house. A ductless mini-split could be the right HVAC system for your home addition if:

  • Your existing system can’t take on the extra room, and you’re not ready to replace everything right away.
  • The old and expanded additions have differing heating and cooling needs.
  • You would like to add air conditioning to your house without putting in or extending the ductwork.
