Do I Need to Install a New HVAC System for a Home Addition?

Whether you’re building a second family room, a guest suite or expanding the kitchen, having more square footage in your home is sure to be handy. Just don’t forget to think over the heating and cooling necessities of the new room. One of those considerations should cover whether you should upgrade your HVAC system for a home addition in Rochester. Our guidebook will help you as you begin the process.

Option 1: No Upgrade Necessary

If the home addition involves expanding an area as opposed to building entirely new rooms, you may not need to upgrade the HVAC system at all. This is most likely the situation if your heating and cooling equipment was too large to begin with. Schedule a load calculation from a professional technician, such as one from Strogen's Service Experts by calling 603-923-4570. This will decide if your existing HVAC setup can manage the upgrades you’ve made to your home.

Option 2: HVAC System Upgrade

Another idea for delivering heat and air conditioning into your home addition is to lengthen the ductwork from your existing forced-air equipment. If you rely on radiators or baseboard heating, you can lengthen hot water piping to the new area.

Bear in mind that, in addition to ductwork or water piping, you might also have to add HVAC equipment to handle the higher load. The ensuing increase in electricity usage might even call for an electrical panel upgrade. If your heating and cooling system is due for a replacement soon, this might be a good option.

Option 3: Install a Ductless Mini-Split

Instead of installing a new unit to manage the extra square footage, you can put in a stand-alone one. Ductless mini-splits are perfect for this. They use two parts. There’s a condensing component that is installed on a slab near your home, akin to an air conditioner. Then there’s the space-saving indoor blower that is placed against the ceiling or wall.

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

Since it includes a wall- or ceiling-mounted air handler, ductwork isn’t necessary. You can even add up to four indoor units with one outdoor unit for zoned heating and cooling in differing areas in your house. A ductless mini-split may be the right HVAC solution for your home addition if:

  • Your current system can’t absorb the additional space, and you’re not ready to replace it all right away.
  • The old and additional rooms have differing heating and cooling needs.
  • You would like to add air conditioning to your home without installing or extending the ductwork.
