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

Whether you’re adding a second family room, a guest suite or expanding the kitchen, having more square footage in your home is sure to be convenient. Just don’t forget to think about the heating and cooling needs of the new room. One of those considerations should cover 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 Necessary 

If the home addition includes expanding an area instead of putting on totally new rooms, you may not need to upgrade the HVAC system at all. This is usually the situation if your heating and cooling system was too large when they were installed. Schedule a load calculation from a professional technician, like one from Service Experts Heating, Air Conditioning & Plumbing by calling 866-397-3787. This will determine if your existing HVAC equipment can take on the changes you’ve made to your residence. 

Option 2: Upgrade Your HVAC System 

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

You should know that, along with ductwork or water piping, you might also have to add HVAC equipment to handle the increased load. The ensuing increase in electricity use could even need an electrical panel upgrade. If your heating and cooling system needs to be replaced soon, this could be a good solution. 

Option 3: Install a Ductless Mini-Split 

In place of installing a new equipment to cover the additional space, you can install a separate one. Ductless mini-splits are great for this. They consist of two parts. There’s a condensing system that is placed on a slab outdoors, much like an air conditioner. Then there’s the small indoor blower that is placed to the ceiling or wall. 

Like a central heat pump, mini-split HVAC systems provide both heating and cooling for all-season comfort from a single setup. 

Since it uses 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 distinct spaces in your residence. A ductless mini-split could be the best HVAC option for your home addition if: 

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