Should You Upgrade Your HVAC System for a Home Addition? 

Whether you’re adding a second family room, a guest area or growing the kitchen, having extra square footage in your residence is sure to be convenient. Just don’t forget to think about the heating and cooling requirements of the new space. One of those factors should cover whether you should upgrade your HVAC system for a home addition in the U.S.. Our instructions will help you as you begin the process. 

Option 1: No Upgrade Required 

If the home addition calls for enlarging an area instead of adding completely new rooms, you may not need to upgrade the HVAC system at all. This is most likely the situation if your heating and cooling system was oversized originally. Get a load calculation from a professional technician, for example one from Service Experts Heating, Air Conditioning & Plumbing by calling 866-397-3787. This will affect if your current HVAC system can handle the upgrades you’ve made to your residence. 

Option 2: Upgrade Your HVAC System 

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

You should know that, along with ductwork or water piping, you could also have to install HVAC equipment to manage the increased load. The following increase in electricity use might even call for a new electrical panel. If your heating and cooling system requires a replacement soon, this may be perfectly acceptable. 

Option 3: Get a Ductless Mini-Split 

Instead of upgrading your existing system to cover the additional space, you can install a freestanding one. Ductless mini-splits are ideal for this. They consist of two parts. There’s a condensing component that is placed on a slab outdoors, akin to an air conditioner. Then there’s the small indoor blower that is installed against the ceiling or wall. 

Similar to a central heat pump, mini-split HVAC systems offer both heating and cooling for continuous comfort from a sole system. 

Since there’s a wall- or ceiling-mounted air handler, no ductwork is required. You can even join up to four indoor units with one outdoor unit for zoned heating and cooling in differing parts of your house. A ductless mini-split may be the ideal HVAC system for your home addition if: 

  • Your current system can’t absorb the added area, and you’re not prepared to replace every part today. 
  • The old and expanded additions have differing heating and cooling needs. 
  • You are looking to add air conditioning to your residence without getting or extending the ductwork.
