Should You Upgrade Your HVAC System for a Home Addition? 

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

Option 1: No Upgrade Required 

If the home addition calls for enlarging a room rather than building completely new rooms, you may not need to enhance the HVAC system at all. This is often the situation if your heating and cooling equipment was too big when they were installed. Request a load calculation from a pro technician, for example one from Service Experts Heating, Air Conditioning & Plumbing by calling 866-397-3787. This will decide if your existing HVAC setup can manage the modifications you’ve made to your home. 

Option 2: Replace Your HVAC System 

Another idea for delivering 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 space. 

Please note that, along with ductwork or water piping, you could also have to add HVAC equipment to handle the increased load. The subsequent increase in electricity consumption could 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: Get a Ductless Mini-Split 

Instead of upgrading your existing equipment to cover the additional square footage, you can get a freestanding one. Ductless mini-splits are perfect for this. They consist of two parts. There’s a condensing system that sits on the ground outdoors, similar to an air conditioner. Then there’s the compact indoor blower that is placed on the ceiling or wall. 

Akin to a central heat pump, mini-split HVAC systems offer both heating and cooling for continual comfort from a sole setup. 

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

  • Your existing system can’t handle the extra room, and you’re not ready to replace everything today. 
  • The old and expanded spaces have different heating and cooling needs. 
  • You want to add air conditioning to your home without installing or lengthening the ductwork.
