Does a Home Addition Mean I Need to Upgrade My HVAC System?

Whether you’re adding a second family room, a guest area or enlarging the kitchen, having extra square footage in your house is sure to be handy. Just remember to think over the heating and cooling necessities of the new area. One of those points should involve whether you should upgrade your HVAC system for a home addition in Boise. Our guide will help you as you get started with the process.

Option 1: No Upgrade Necessary

If the home addition involves enlarging a room instead of building entirely new rooms, you may not need to enhance the HVAC system at all. This is most likely the instance if your heating and cooling equipment was oversized to begin with. Get a load calculation from an Expert technician, for example one from TML Service Experts by calling 208-488-4892. This will decide if your present HVAC system can take on the changes you’ve made to your house.

Option 2: HVAC System Upgrade

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

Bear in mind that, along with ductwork or water piping, you may also have to add HVAC equipment to take care of the bigger load. The following increase in electricity use may even call for an electrical panel upgrade. If your heating and cooling system needs to be replaced soon, this might be perfectly acceptable.

Option 3: Add a Ductless Mini-Split

Rather than upgrading your existing unit to handle the additional square footage, you can put in an independent one. Ductless mini-splits are ideal for this. They consist of two parts. There’s a condensing system that is placed on the ground outside, akin to an air conditioner. Then there’s the space-saving indoor blower that is installed against the ceiling or wall.

Akin to a central heat pump, mini-split HVAC systems deliver both heating and cooling for continuous comfort from a sole piece of equipment.

Since there’s a wall- or ceiling-mounted air handler, you don’t need ductwork. You can even add up to four indoor blowers with one outdoor unit for zoned heating and cooling in differing parts of your house. A ductless mini-split may be the right HVAC option for your home addition if:

  • Your existing system can’t absorb the additional space, and you’re not able to replace everything right away.
  • The old and expanded spaces have differing heating and cooling needs.
  • You want to add air conditioning to your home without installing or lengthening the ductwork.
