Does a Home Addition Require Upgrading My HVAC System?

Whether you’re putting on a second family room, a guest area or expanding the kitchen, having extra square footage in your home is sure to be convenient. Just keep in mind you need to consider the heating and cooling requirements of the new space. One of those factors should involve whether you should upgrade your HVAC system for a home addition in San Antonio. Our guidebook will help you as you take the first step in the process.

Option 1: No Upgrade Necessary

If the home addition includes growing a space 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 units were oversized when they were installed. Request a load calculation from a pro technician, such as one from Aramendia Plumbing, Heating and Air by calling 210-404-4233. This will decide if your present HVAC equipment can take on the changes you’ve made to your residence.

Option 2: HVAC System Upgrade

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

You should know that, adding ductwork or water piping, you might also have to add HVAC equipment to take care of the higher load. The subsequent increase in electricity usage could even require an enhanced electrical panel. If your heating and cooling system needs to be replaced soon, this might be perfectly acceptable.

Option 3: Add a Ductless Mini-Split

Instead of upgrading your existing system to manage the added space, you can put in a freestanding one. Ductless mini-splits are perfect for this. They have two parts. There’s a condensing system that sits on the ground outside, much like an air conditioner. Then there’s the space-saving indoor blower that mounts to the ceiling or wall.

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

Since there’s 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 different areas in your home. A ductless mini-split may be the best HVAC system for your home addition if:

  • Your existing system can’t absorb the extra space, and you’re not able to replace everything right away.
  • The old and additional additions have varying heating and cooling needs.
  • You want to add air conditioning to your home without putting in or extending the ductwork.
