Do I Need to Upgrade My HVAC System for a Home Addition?

Whether you’re putting on a second family room, a guest suite or growing the kitchen, having extra square footage in your home is sure to be convenient. Just remember to think over the heating and cooling requirements of the new space. One of those considerations should incorporate whether you should upgrade your HVAC system for a home addition in the Niagara Region. Our guidebook will help you as you begin the process.

Option 1: No Upgrade Needed

If the home addition calls for enlarging a space as opposed to building totally new rooms, you may not need to upgrade the HVAC system at all. This is usually the case if your heating and cooling units were too big when they were installed. Get a load calculation from a pro technician, like one from Service Experts Heating & Air Conditioning by calling 289-273-2229. This will decide if your existing HVAC equipment can manage the upgrades you’ve made to your home.

Option 2: Install a New HVAC System

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

Be mindful that, along with ductwork or water piping, you might also have to put in HVAC equipment to take care of the higher load. The following increase in electricity consumption might even call for an enhanced electrical panel. If your heating and cooling system needs to be replaced soon, this may be a good option.

Option 3: Install a Ductless Mini-Split

Rather than installing a new unit to handle the additional square footage, you can get a stand-alone one. Ductless mini-splits are perfect for this. They have two parts. There’s a condensing component that sits on cement outdoors, similar to an air conditioner. Then there’s the compact indoor blower that mounts to the ceiling or wall.

Like a central heat pump, mini-split HVAC systems provide both heating and cooling for continuous comfort from a single setup.

Since it has a wall- or ceiling-mounted air handler, you don’t need ductwork. You can even link up to four indoor air handlers with one outdoor unit for zoned heating and cooling in differing parts of your residence. A ductless mini-split could be the best HVAC system for your home addition if:

  • Your present system can’t absorb the additional room, and you’re not ready to replace every part today.
  • The old and expanded spaces have different heating and cooling needs.
  • You would like to add air conditioning to your house without putting in or extending the ductwork.
