Does a Home Addition Require 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 handy. Just keep in mind you need to think about the heating and cooling requirements of the new room. One of those considerations should cover whether you should upgrade your HVAC system for a home addition in Canada. Our instructions will help you as you begin the process.

Option 1: No Upgrade Necessary

If the home addition involves expanding a room instead of building entirely new rooms, you may not need to upgrade the HVAC system at all. This is usually the instance if your heating and cooling system was too big originally. Book a load calculation from an Expert technician, for example one from Service Experts Heating & Air Conditioning by calling 866-397-3787. This will affect if your present HVAC setup can handle the changes you’ve made to your house.

Option 2: Upgrade Your HVAC System

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

Please note that, along with ductwork or water piping, you might also have to add HVAC equipment to manage the higher load. The ensuing increase in electricity consumption may even require an enhanced electrical panel. If your heating and cooling system is due for a replacement soon, this might be a good solution.

Option 3: Get a Ductless Mini-Split

In place of upgrading your existing unit to cover the extra square footage, you can get a separate one. Ductless mini-splits are perfect for this. They have two parts. There’s a condensing unit that sits on the ground outside, much like an air conditioner. Then there’s the small indoor blower that mounts to the ceiling or wall.

Like a central heat pump, mini-split HVAC systems deliver both heating and cooling for constant comfort from one setup.

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

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