Does a Home Addition Call for Upgrading My HVAC System?

Whether you’re adding a second family room, a guest space or growing the kitchen, having additional square footage in your home is sure to be handy. Just remember to consider the heating and cooling needs of the new area. One of those considerations should cover whether you should upgrade your HVAC system for a home addition in Oakville. Our guide will help you as you take the first step in the process.

Option 1: No Upgrade Necessary

If the home addition involves expanding a space as opposed to building completely new rooms, you may not need to enhance the HVAC system at all. This is often the situation if your heating and cooling units were too big when they were installed. Schedule a load calculation from an Expert technician, like one from Abbey Air Service Experts by calling 289-813-5566. This will figure out if your existing HVAC system can handle the changes you’ve made to your residence.

Option 2: Replace Your HVAC System

Another solution for bringing heat and air conditioning into your home addition is to extend the ductwork from your existing forced-air unit. If you rely on radiators or baseboard heating, you can extend hot water piping to the new room.

Be aware that, along with ductwork or water piping, you might also have to install HVAC equipment to manage the higher load. The ensuing increase in electricity use may even need a new electrical panel. If your heating and cooling system is due for a replacement soon, this could be a good option.

Option 3: Install a Ductless Mini-Split

Instead of getting a new system to cover the additional area, you can add a separate one. Ductless mini-splits are great for this. They use two parts. There’s a condensing unit that sits on a slab near your home, similar to an air conditioner. Then there’s the compact indoor blower that is placed on the ceiling or wall.

Like a central heat pump, mini-split HVAC systems offer both heating and cooling for continuous comfort from one system.

Since it includes a wall- or ceiling-mounted air handler, no ductwork is required. You can even add up to four indoor units with one outdoor unit for zoned heating and cooling in differing spaces in your home. A ductless mini-split may be the ideal HVAC option for your home addition if:

  • Your existing system can’t handle the added area, and you’re not prepared to replace every part today.
  • The old and new rooms have varying heating and cooling needs.
  • You would like to add air conditioning to your home without installing or lengthening the ductwork.
