Is It Vital to Get 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 consider the heating and cooling requirements of the new area. One of those factors should incorporate whether you should upgrade your HVAC system for a home addition in Houston. Our guide will help you as you take the first step in the process.

Option 1: No Upgrade Required

If the home addition includes growing a space as opposed to putting on completely new rooms, you may not need to improve the HVAC system at all. This is often the instance if your heating and cooling system was too large to begin with. Get a load calculation from a professional technician, such as one from Service Experts Heating & Air Conditioning by calling (713) 352-7887. This will affect if your current HVAC setup can take on the modifications you’ve made to your home.

Option 2: HVAC System Upgrade

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

Be aware that, in addition to ductwork or water piping, you might also have to add HVAC equipment to manage the increased load. The subsequent increase in electricity use could even require a new electrical panel. If your heating and cooling system requires a replacement soon, this might be a good option.

Option 3: Install a Ductless Mini-Split

In place of getting a new system 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 is installed on a slab near your home, similar to an air conditioner. Then there’s the compact indoor blower that is placed to the ceiling or wall.

Similar to a central heat pump, mini-split HVAC systems provide both heating and cooling for constant comfort from one solution.

Since there’s a wall- or ceiling-mounted air handler, ductwork isn’t necessary. You can even link up to four indoor units with one outdoor unit for zoned heating and cooling in differing 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 additional space, and you’re not prepared to replace every part right away.
  • The old and new rooms have varying heating and cooling needs.
  • You want to add air conditioning to your home without putting in or lengthening the ductwork.
