Is It Necessary to Upgrade My HVAC System for a Home Addition?

Whether you’re building a second family room, a guest area or growing the kitchen, having additional square footage in your residence is sure to be convenient. Just keep in mind you need to think over 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 Hilton Head Island. Our instructions will help you as you begin the process.

Option 1: No Upgrade Required

If the home addition involves enlarging a space rather than putting on completely new rooms, you may not need to improve the HVAC system at all. This is most likely the case if your heating and cooling units were too big when they were installed. Schedule a load calculation from a pro technician, such as one from Epperson Service Experts by calling 843-619-3781. This will decide if your present HVAC setup can manage the changes you’ve made to your house.

Option 2: Upgrade Your HVAC System

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

Bear in mind that, adding ductwork or water piping, you could also have to add HVAC equipment to take care of the bigger load. The ensuing increase in electricity consumption could even require an electrical panel upgrade. If your heating and cooling system needs to be replaced soon, this could be a good option.

Option 3: Install a Ductless Mini-Split

Rather than getting a new system to manage the additional square footage, you can add an independent one. Ductless mini-splits are perfect for this. They consist of two parts. There’s a condensing system that is placed on cement outside, akin to an air conditioner. Then there’s the small indoor blower that is installed on the ceiling or wall.

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

Since there’s a wall- or ceiling-mounted air handler, zero ductwork is required. You can even add up to four indoor units with one outdoor unit for zoned heating and cooling in different areas in your house. A ductless mini-split might be the right HVAC option for your home addition if:

  • Your existing system can’t absorb the additional space, and you’re not prepared to replace everything today.
  • The old and additional rooms have varying heating and cooling needs.
  • You want to add air conditioning to your residence without getting or extending the ductwork.
