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 additional square footage in your residence is sure to be handy. Just don’t forget to consider the heating and cooling necessities of the new space. One of those points should involve whether you should upgrade your HVAC system for a home addition in the U.S.. Our guide will help you as you take the first step in the process. 

Option 1: No Upgrade Needed 

If the home addition involves growing a space rather than adding entirely new rooms, you may not need to improve the HVAC system at all. This is usually the case if your heating and cooling units were oversized 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 decide if your existing HVAC equipment can take on the changes you’ve made to your residence. 

Option 2: Replace Your HVAC System 

Another idea for bringing heat and air conditioning into your home addition is to lengthen the ductwork from your present forced-air equipment. If you have radiators or baseboard heating, you can lengthen hot water piping to the new space. 

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

Option 3: Install a Ductless Mini-Split 

Rather than installing a new unit to manage the extra area, you can install an independent one. Ductless mini-splits are perfect for this. They consist of two parts. There’s a condensing system that is installed on a slab outside, akin to an air conditioner. Then there’s the small 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 all-season comfort from a sole setup. 

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

  • Your present system can’t absorb the additional area, and you’re not ready to replace every part right away. 
  • The old and expanded rooms have different heating and cooling needs. 
  • You want to add air conditioning to your home without installing or extending the ductwork.
