Should You Install a New HVAC System for a Home Addition? 

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 consider the heating and cooling necessities of the new space. One of those points should incorporate whether you should upgrade your HVAC system for a home addition in the U.S.. Our guidebook will help you as you get started with the process. 

Option 1: No Upgrade Needed 

If the home addition includes enlarging a space as opposed to putting on totally new rooms, you may not need to upgrade the HVAC system at all. This is most likely the instance if your heating and cooling system was too large to begin with. Request a load calculation from an Expert technician, for example one from Service Experts Heating, Air Conditioning & Plumbing by calling 866-397-3787. This will determine if your existing HVAC setup can manage the modifications you’ve made to your home. 

Option 2: HVAC System Upgrade 

Another solution for getting 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 lengthen hot water piping to the new area. 

Bear in mind that, in addition to ductwork or water piping, you might also have to put in HVAC equipment to handle the increased load. The following increase in electricity consumption could even need an electrical panel upgrade. If your heating and cooling system is due for a replacement soon, this could be a good solution. 

Option 3: Add a Ductless Mini-Split 

In place of getting a new unit to cover the additional area, you can put in an independent one. Ductless mini-splits are ideal for this. They use two parts. There’s a condensing system that is placed on a slab outside, much like an air conditioner. Then there’s the space-saving indoor blower that is installed to the ceiling or wall. 

Akin to a central heat pump, mini-split HVAC systems offer both heating and cooling for constant 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 join up to four indoor air handlers with one outdoor unit for zoned heating and cooling in distinct areas in your home. A ductless mini-split may be the best HVAC system for your home addition if: 

  • Your current system can’t absorb the added space, and you’re not able to replace it all today. 
  • The old and additional spaces have differing heating and cooling needs. 
  • You want to add air conditioning to your residence without getting or lengthening the ductwork.
