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

Whether you’re building a second family room, a guest area or expanding the kitchen, having extra square footage in your residence is sure to prove useful. Just keep in mind you need to think about the heating and cooling needs of the new space. One of those factors should cover whether you should upgrade your HVAC system for a home addition in the U.S.. Our instructions will help you as you take the first step in the process.

Option 1: No Upgrade Needed

If the home addition includes expanding a room instead of putting on entirely new rooms, you may not need to enhance the HVAC system at all. This is usually the case if your heating and cooling equipment was too big originally. Book 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 existing HVAC system can manage the changes you’ve made to your home.

Option 2: Upgrade Your HVAC System

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

Be aware that, in addition to ductwork or water piping, you may also have to install HVAC equipment to take care of the bigger load. The ensuing increase in electricity consumption could even call for an electrical panel upgrade. If your heating and cooling system needs to be replaced soon, this might be perfectly acceptable.

Option 3: Get a Ductless Mini-Split

Rather than getting a new unit to cover the added area, you can install a separate one. Ductless mini-splits are perfect for this. They have two parts. There’s a condensing system that is placed on cement outside, akin to an air conditioner. Then there’s the space-saving indoor blower that mounts on the ceiling or wall.

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

Since it has a wall- or ceiling-mounted air handler, zero ductwork is required. You can even link up to four indoor units with one outdoor unit for zoned heating and cooling in differing areas in your home. A ductless mini-split might be the right HVAC system for your home addition if:

    • Your present system can’t take on the extra room, and you’re not ready to replace everything right now.
    • The old and new additions have varying heating and cooling needs.
    • You are looking to add air conditioning to your house without putting in or adding on to the ductwork.
