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

Whether you’re adding a second family room, a guest suite or growing the kitchen, having additional square footage in your home is sure to prove useful. Just keep in mind you need to think over the heating and cooling necessities of the new room. One of those points should include 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 Necessary 

If the home addition calls for growing an area instead of building completely new rooms, you may not need to improve the HVAC system at all. This is most likely the case if your heating and cooling units were oversized 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 determine if your current HVAC setup can handle the upgrades you’ve made to your residence. 

Option 2: HVAC System Upgrade 

Another option for getting 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. 

Please note that, along with ductwork or water piping, you could also have to put in HVAC equipment to manage the bigger load. The subsequent increase in electricity consumption might even call for an electrical panel upgrade. If your heating and cooling system requires a replacement soon, this might be perfectly acceptable. 

Option 3: Add a Ductless Mini-Split 

In place of upgrading your existing system to handle 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 component that sits on cement outdoors, much like an air conditioner. Then there’s the small indoor blower that mounts on the ceiling or wall. 

Similar to a central heat pump, mini-split HVAC systems provide both heating and cooling for year-round comfort from one system. 

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 different spaces in your home. A ductless mini-split may be the right HVAC system for your home addition if: 

  • Your present system can’t handle the added square footage, and you’re not prepared to replace it all right away. 
  • The old and expanded spaces have differing heating and cooling needs. 
  • You want to add air conditioning to your home without getting or extending the ductwork.
