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

Whether you’re adding a second family room, a guest suite or growing the kitchen, having additional square footage in your house is sure to prove useful. Just keep in mind you need to consider the heating and cooling requirements of the new space. One of those considerations should cover whether you should upgrade your HVAC system for a home addition in Oklahoma City. Our guidebook will help you as you take the first step in the process.

Option 1: No Upgrade Needed

If the home addition calls for expanding an area rather than putting on totally new rooms, you may not need to upgrade the HVAC system at all. This is usually the case if your heating and cooling system was oversized when they were installed. Schedule a load calculation from a pro technician, for example one from Gordon's Service Experts by calling 405-432-2197. This will decide if your current HVAC equipment can manage the modifications you’ve made to your home.

Option 2: Upgrade Your HVAC System

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

You should know that, in addition to ductwork or water piping, you could also have to install HVAC equipment to handle the higher load. The resulting increase in electricity use could even call for an electrical panel upgrade. If your heating and cooling system needs to be replaced soon, this may be a good solution.

Option 3: Get a Ductless Mini-Split

Rather than getting a new system to manage the additional square footage, you can put in an independent one. Ductless mini-splits are great for this. They consist of two parts. There’s a condensing unit that sits on cement near your home, much like an air conditioner. Then there’s the sleek indoor blower that is placed against the ceiling or wall.

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

Since there’s a wall- or ceiling-mounted air handler, zero ductwork is required. You can even add up to four indoor blowers with one outdoor unit for zoned heating and cooling in differing parts of your home. A ductless mini-split may be the right HVAC option for your home addition if:

  • Your present system can’t handle the extra space, and you’re not able to replace everything right away.
  • The old and expanded spaces have varying heating and cooling needs.
  • You are looking to add air conditioning to your residence without getting or extending the ductwork.
