Should You Upgrade Your HVAC System for a Home Addition? 

Whether you’re building a second family room, a guest space or expanding the kitchen, having more square footage in your house is sure to prove useful. Just don’t forget to think over the heating and cooling necessities of the new room. One of those factors should include whether you should upgrade your HVAC system for a home addition in the U.S.. Our guidebook will help you as you begin the process. 

Option 1: No Upgrade Necessary 

If the home addition includes enlarging an area as opposed to 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 too big originally. Request a load calculation from a pro technician, such as 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 home. 

Option 2: HVAC System Upgrade 

Another option for getting heat and air conditioning into your home addition is to lengthen the ductwork from your present forced-air system. If you have radiators or baseboard heating, you can add hot water piping to the new area. 

Please note that, adding ductwork or water piping, you could also have to add HVAC equipment to manage the higher load. The ensuing increase in electricity usage might even require an electrical panel upgrade. If your heating and cooling system needs to be replaced soon, this may be a good solution. 

Option 3: Get a Ductless Mini-Split 

In place of upgrading your existing unit to cover the added space, you can get a separate one. Ductless mini-splits are ideal for this. They have two parts. There’s a condensing unit that sits on the ground outdoors, much like an air conditioner. Then there’s the space-saving indoor blower that is placed on the ceiling or wall. 

Similar to a central heat pump, mini-split HVAC systems offer both heating and cooling for constant comfort from a single piece of equipment. 

Since it uses a wall- or ceiling-mounted air handler, ductwork isn’t necessary. 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 could be the right HVAC system for your home addition if: 

  • Your existing system can’t take on the extra area, and you’re not able to replace every part today. 
  • The old and new rooms have varying heating and cooling needs. 
  • You want to add air conditioning to your home without installing or adding on to the ductwork.
