Do I Need to Upgrade My HVAC System for a Home Addition?

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

Option 1: No Upgrade Needed

If the home addition involves enlarging a room as opposed to building totally new rooms, you may not need to enhance the HVAC system at all. This is often the case if your heating and cooling equipment was too large originally. Request a load calculation from an Expert technician, such as 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 idea for delivering heat and air conditioning into your home addition is to extend the ductwork from your existing forced-air equipment. If you use radiators or baseboard heating, you can lengthen hot water piping to the new space.

Please note that, adding ductwork or water piping, you could also have to put in 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 requires a replacement soon, this might be a good solution.

Option 3: Get a Ductless Mini-Split

In place of upgrading your existing equipment to manage the extra square footage, you can put in an independent one. Ductless mini-splits are ideal for this. They have two parts. There’s a condensing unit that sits on a slab outdoors, similar to an air conditioner. Then there’s the compact indoor blower that mounts against the ceiling or wall.

Similar to a central heat pump, mini-split HVAC systems provide both heating and cooling for continuous 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 air handlers 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 take on the additional area, and you’re not able to replace it all right away.
  • The old and new spaces have differing heating and cooling needs.
  • You want to add air conditioning to your residence without putting in or extending the ductwork.
