Do you have plans to add to your home? Before you build a new addition, take a look at what you need to know about AC unit installation.
What Are Your Addition Installation Options?
The easiest and least costly option is to not install or extend the HVAC system into the addition. But this isn't a practical idea. Without cooling, the addition won't just feel hot. Not only does an AC system cool the air, it also dehumidifies it. Failure to adequately dehumidify the indoor air could result in excess dampness and mold or mildew growth.
If your addition needs air conditioning, the top installation options to explore include:
- An extension. An HVAC contractor could extend the ductwork into the addition area. The contractor will need to assess the addition's space and other factors (such as insulation and air leaks) to make sure the AC unit is the right size.
- A new system. What happens if the existing air conditioner isn't the right size match for the addition's extension? You may need to replace the old unit with a newer, larger one.
- A ductless system. A ductless mini-split air conditioner cools by zones (or areas). You won't need to add ducts or worry about the size of the existing AC unit. This system will operate on its own, keeping the addition cool and comfortable.
Now that you know more about your options, it's time to take the next step and select the right cooling system for your home's addition.
How Should You Choose an Air Conditioner for an Addition?
The best time to decide on AC installation is before you begin the construction process. This gives you time to plan for ductwork and other related issues. If you're ready to start planning, but don't know which AC option is right for your addition, consider:
- The existing system. Did you recently install a new air conditioner? An addition that creates a significant size difference in your home may require you to replace a brand-new unit. If you have a new system, a mini-split option may save you money.
- How much use the addition will get. Is the addition a major part of your home? If you'll only use it some of the time, a ductless mini-split zone cooling system is an energy-efficient choice to explore.
- The rest of your home's needs. Is the existing AC unit efficient? If not, a full replacement can cool your home more effectively.
If you're still not sure what type of air conditioner you need for your home's addition, discuss the choices with an HVAC contractor. A qualified professional can help you to select the ideal AC system.
