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

Whether you’re building a second family room, a guest suite or growing the kitchen, having extra square footage in your home is sure to be convenient. Just remember to think over the heating and cooling needs of the new space. One of those considerations should involve whether you should upgrade your HVAC system for a home addition in the U.S.. Our guide will help you as you get started with the process. 

Option 1: No Upgrade Necessary 

If the home addition includes growing an area as opposed to adding entirely new rooms, you may not need to upgrade the HVAC system at all. This is usually the situation if your heating and cooling units were too large to begin with. Book a load calculation from a professional technician, like one from Service Experts Heating, Air Conditioning & Plumbing by calling 866-397-3787. This will affect if your current HVAC system can take on the modifications you’ve made to your house. 

Option 2: Upgrade Your HVAC System 

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

Please note that, adding ductwork or water piping, you may also have to install HVAC equipment to handle the bigger load. The ensuing increase in electricity use might even require an electrical panel upgrade. If your heating and cooling system needs to be replaced soon, this may be perfectly acceptable. 

Option 3: Get a Ductless Mini-Split 

Rather than upgrading your existing equipment to cover the extra square footage, you can add a stand-alone one. Ductless mini-splits are perfect for this. They consist of two parts. There’s a condensing system that sits on a slab outdoors, much like an air conditioner. Then there’s the compact indoor blower that mounts to the ceiling or wall. 

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

Since it includes a wall- or ceiling-mounted air handler, no ductwork is required. You can even link 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 ideal HVAC option for your home addition if: 

  • Your existing system can’t handle the added area, and you’re not able to replace it all right away. 
  • The old and new additions have differing heating and cooling needs. 
  • You would like to add air conditioning to your house without getting or adding on to the ductwork.
