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

Whether you’re putting on a second family room, a guest area or growing the kitchen, having more square footage in your home is sure to be convenient. Just remember to think about the heating and cooling needs of the new area. One of those factors should cover whether you should upgrade your HVAC system for a home addition in the U.S.. Our guide will help you as you begin the process. 

Option 1: No Upgrade Needed 

If the home addition involves expanding an area rather than building completely new rooms, you may not need to improve the HVAC system at all. This is often the instance if your heating and cooling units were oversized when they were installed. Book a load calculation from a pro technician, for example one from Service Experts Heating, Air Conditioning & Plumbing by calling 866-397-3787. This will affect if your present HVAC system can manage the changes you’ve made to your home. 

Option 2: Install a New HVAC System 

Another option for getting heat and air conditioning into your home addition is to extend the ductwork from your existing forced-air unit. If you use radiators or baseboard heating, you can extend hot water piping to the new space. 

Be mindful that, along with ductwork or water piping, you might also have to put in HVAC equipment to take care of the higher load. The resulting increase in electricity consumption may even call for an electrical panel upgrade. If your heating and cooling system needs to be replaced soon, this may be a good solution. 

Option 3: Add a Ductless Mini-Split 

Instead of upgrading your existing equipment to manage the added space, you can put in a separate one. Ductless mini-splits are great for this. They have two parts. There’s a condensing unit that is placed on the ground outdoors, similar to an air conditioner. Then there’s the small indoor blower that is installed against the ceiling or wall. 

Akin to a central heat pump, mini-split HVAC systems provide both heating and cooling for continual comfort from a single system. 

Since it uses a wall- or ceiling-mounted air handler, no ductwork is required. You can even join up to four indoor blowers with one outdoor unit for zoned heating and cooling in different spaces in your home. A ductless mini-split might be the ideal HVAC solution for your home addition if: 

  • Your present system can’t handle the extra room, and you’re not prepared to replace everything today. 
  • The old and expanded rooms have different heating and cooling needs. 
  • You would like to add air conditioning to your residence without putting in or extending the ductwork.
