Do I Need to Install a New HVAC System for a Home Addition?

Whether you’re putting on a second family room, a guest area or enlarging the kitchen, having more square footage in your residence is sure to prove useful. Just keep in mind you need 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 La Porte. Our guide will help you as you begin the process.

Option 1: No Upgrade Necessary

If the home addition involves expanding an area rather than adding entirely new rooms, you may not need to upgrade the HVAC system at all. This is often the case if your heating and cooling equipment was too large when they were installed. Get a load calculation from a pro technician, such as one from Finch Air Conditioning & Heating by calling 281-407-9478. This will decide if your present HVAC setup can take on the changes you’ve made to your house.

Option 2: Install a New HVAC System

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

Bear in mind that, in addition to ductwork or water piping, you may also have to install HVAC equipment to handle the higher load. The subsequent increase in electricity consumption may even need a new electrical panel. If your heating and cooling system requires a replacement soon, this may be a good option.

Option 3: Install a Ductless Mini-Split

In place of getting a new unit to handle the additional area, you can put in a separate one. Ductless mini-splits are great for this. They have two parts. There’s a condensing component that is placed on a slab outdoors, akin to an air conditioner. Then there’s the compact indoor blower that is installed to the ceiling or wall.

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

Since there’s a wall- or ceiling-mounted air handler, you don’t need ductwork. You can even add up to four indoor air handlers with one outdoor unit for zoned heating and cooling in distinct areas in your house. A ductless mini-split might be the best HVAC solution for your home addition if:

  • Your current system can’t take on the added square footage, and you’re not ready to replace everything right now.
  • The old and additional spaces have different heating and cooling needs.
  • You would like to add air conditioning to your residence without putting in or adding on to the ductwork.
