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

Whether you’re putting on a second family room, a guest suite or enlarging the kitchen, having extra square footage in your house is sure to be handy. Just remember to think about the heating and cooling necessities of the new area. One of those points should cover whether you should upgrade your HVAC system for a home addition in the U.S.. Our instructions will help you as you get started with the process. 

Option 1: No Upgrade Required 

If the home addition involves growing a space as opposed to putting on entirely new rooms, you may not need to improve the HVAC system at all. This is most likely the situation if your heating and cooling system was too big originally. Request a load calculation from a professional technician, like one from Service Experts Heating, Air Conditioning & Plumbing by calling 866-397-3787. This will figure out if your existing HVAC setup can take on the upgrades you’ve made to your house. 

Option 2: Install a New HVAC System 

Another idea for bringing heat and air conditioning into your home addition is to add on to the ductwork from your existing forced-air system. If you rely on radiators or baseboard heating, you can add hot water piping to the new area. 

Be mindful that, along with ductwork or water piping, you may also have to put in HVAC equipment to handle the increased load. The subsequent increase in electricity consumption might even require a new electrical panel. If your heating and cooling system needs to be replaced soon, this could be perfectly acceptable. 

Option 3: Get a Ductless Mini-Split 

In place of getting a new equipment to manage the added space, you can add a freestanding one. Ductless mini-splits are ideal for this. They have two parts. There’s a condensing system that is placed on the ground outside, akin to an air conditioner. Then there’s the compact indoor blower that is placed to the ceiling or wall. 

Similar to a central heat pump, mini-split HVAC systems offer both heating and cooling for all-season comfort from one piece of equipment. 

Since it has 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 distinct spaces in your residence. A ductless mini-split might be the right HVAC system for your home addition if: 

  • Your existing system can’t absorb the added space, and you’re not able to replace everything today. 
  • The old and new additions have varying heating and cooling needs. 
  • You would like to add air conditioning to your residence without putting in or lengthening the ductwork.
