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

Whether you’re adding a second family room, a guest space or enlarging the kitchen, having extra square footage in your home is sure to be handy. Just remember to think about the heating and cooling requirements of the new room. One of those points should incorporate 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 Required 

If the home addition includes expanding a space rather than building entirely new rooms, you may not need to upgrade the HVAC system at all. This is often the instance if your heating and cooling equipment was too large originally. Get a load calculation from an Expert technician, such as one from Service Experts Heating, Air Conditioning & Plumbing by calling 866-397-3787. This will decide if your existing HVAC equipment can take on the changes you’ve made to your home. 

Option 2: Replace Your HVAC System 

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

Please note that, in addition to ductwork or water piping, you could also have to install HVAC equipment to handle the increased load. The subsequent increase in electricity use could even require an electrical panel upgrade. If your heating and cooling system is due for a replacement soon, this may be perfectly acceptable. 

Option 3: Add a Ductless Mini-Split 

Rather than installing a new equipment to cover the added square footage, you can install a stand-alone one. Ductless mini-splits are great for this. They consist of two parts. There’s a condensing unit that sits on a slab outdoors, much like an air conditioner. Then there’s the space-saving indoor blower that mounts on the ceiling or wall. 

Like a central heat pump, mini-split HVAC systems provide both heating and cooling for continual comfort from a single piece of equipment. 

Since it includes a wall- or ceiling-mounted air handler, no ductwork is required. You can even add up to four indoor air handlers with one outdoor unit for zoned heating and cooling in distinct spaces in your home. A ductless mini-split may be the right HVAC system for your home addition if: 

  • Your existing system can’t handle the additional room, and you’re not prepared to replace it all right away. 
  • The old and new spaces have different heating and cooling needs. 
  • You want to add air conditioning to your house without getting or extending the ductwork.
