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

Whether you’re building a second family room, a guest space or enlarging the kitchen, having additional square footage in your home is sure to be convenient. Just don’t forget to think about the heating and cooling necessities of the new area. One of those points should involve whether you should upgrade your HVAC system for a home addition in Tempe. Our guidebook will help you as you get started with the process.

Option 1: No Upgrade Necessary

If the home addition involves enlarging a room instead of putting on totally new rooms, you may not need to improve the HVAC system at all. This is usually the case if your heating and cooling equipment was too large originally. Request a load calculation from an Expert technician, for example one from Bob Brown Service Experts by calling 623-243-4517. This will decide if your present HVAC setup can handle the modifications you’ve made to your home.

Option 2: Install a New HVAC System

Another solution for delivering heat and air conditioning into your home addition is to lengthen the ductwork from your existing forced-air equipment. If you rely on radiators or baseboard heating, you can extend hot water piping to the new space.

You should know that, adding ductwork or water piping, you might also have to add HVAC equipment to handle the bigger load. The subsequent increase in electricity usage might even need an electrical panel upgrade. If your heating and cooling system needs to be replaced soon, this might be a good solution.

Option 3: Get a Ductless Mini-Split

In place of upgrading your existing unit to cover the extra square footage, you can put in an independent one. Ductless mini-splits are great for this. They use two parts. There’s a condensing unit that sits on cement near your home, akin to an air conditioner. Then there’s the compact indoor blower that mounts against the ceiling or wall.

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

Since it links with a wall- or ceiling-mounted air handler, ductwork isn’t necessary. You can even link 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 right HVAC option for your home addition if:

  • Your existing system can’t absorb the added area, and you’re not ready to replace it all today.
  • The old and new spaces have varying heating and cooling needs.
  • You want to add air conditioning to your house without getting or extending the ductwork.
