Should You Upgrade Your HVAC System for a Home Addition? 

Whether you’re putting on a second family room, a guest suite or growing the kitchen, having extra square footage in your residence is sure to be convenient. Just don’t forget to think over the heating and cooling requirements of the new space. One of those considerations should cover whether you should upgrade your HVAC system for a home addition in the U.S.. Our guidebook will help you as you get started with the process. 

Option 1: No Upgrade Required 

If the home addition includes enlarging an area rather than adding completely new rooms, you may not need to enhance the HVAC system at all. This is often the instance if your heating and cooling equipment was oversized originally. Schedule a load calculation from a pro technician, like one from Service Experts Heating, Air Conditioning & Plumbing by calling 866-397-3787. This will decide if your current HVAC system can manage the changes you’ve made to your house. 

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 current forced-air equipment. If you rely on radiators or baseboard heating, you can extend hot water piping to the new area. 

Please note that, along with ductwork or water piping, you could also have to add HVAC equipment to take care of the increased load. The resulting increase in electricity consumption could even need a new electrical panel. If your heating and cooling system requires a replacement soon, this might be perfectly acceptable. 

Option 3: Get a Ductless Mini-Split 

In place of getting a new unit to manage the additional space, you can add an independent one. Ductless mini-splits are perfect for this. They have two parts. There’s a condensing component that sits on cement near your home, much like an air conditioner. Then there’s the small indoor blower that mounts against the ceiling or wall. 

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

Since it includes 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 distinct parts of your home. A ductless mini-split may be the best HVAC solution for your home addition if: 

  • Your current system can’t handle the additional room, and you’re not ready to replace every part right now. 
  • The old and new rooms have varying heating and cooling needs. 
  • You would like to add air conditioning to your house without installing or extending the ductwork.
