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

Whether you’re putting on a second family room, a guest space or expanding the kitchen, having additional square footage in your house is sure to be handy. Just keep in mind you need to think about the heating and cooling needs of the new area. One of those points should involve 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 involves growing an area instead of putting on entirely new rooms, you may not need to improve the HVAC system at all. This is usually the situation if your heating and cooling system was too big when they were installed. Get a load calculation from a pro technician, like one from Service Experts Heating, Air Conditioning & Plumbing by calling 866-397-3787. This will figure out if your present HVAC system can manage the upgrades you’ve made to your house.

Option 2: HVAC System Upgrade

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

Bear in mind that, adding ductwork or water piping, you may also have to put in HVAC equipment to manage the higher load. The ensuing increase in electricity consumption might even need an enhanced electrical panel. 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 upgrading your existing unit to handle the added area, you can get a stand-alone one. Ductless mini-splits are ideal for this. They have two parts. There’s a condensing component that is placed on the ground near your home, akin to an air conditioner. Then there’s the small indoor blower that mounts against the ceiling or wall.

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

Since it includes a wall- or ceiling-mounted air handler, ductwork isn’t necessary. You can even add up to four indoor air handlers with one outdoor unit for zoned heating and cooling in different areas in your house. A ductless mini-split may be the best HVAC system for your home addition if:

    • Your present system can’t absorb the added square footage, and you’re not able to replace every part right now.
    • The old and additional spaces have differing heating and cooling needs.
    • You are looking to add air conditioning to your home without getting or adding on to the ductwork.
