# Heating And Cooling The 2-Story Addition You're Planning To Build > If you're already considering options for heating and cooling your 2-story addition, you’re on the right track. Here are the essentials. ![heating and cooling 2-story addition, Boston, Massachusetts](https://bc.rodenhiser.com/wp-content/uploads/2013/02/heating-an-addition.jpg "heating an addition")If you are already considering options for heating and cooling your planned second-story addition, you’re on the right track. Whether you choose to overhaul your entire home-comfort system, or if simply extending or augmenting your current system is the leading solution, you'll want to ensure long-term satisfaction, home comfort and energy efficiency by carefully exploring all of your choices. ![heating and cooling 2-story addition, Boston, Massachusetts](https://bc.rodenhiser.com/wp-content/uploads/2013/02/heating-an-addition.jpg "heating an addition") Ensure your HVAC installer calculates the home's heat gain/loss before proceeding, as well as that of the new addition. Knowing how much heating and cooling is required is an essential step in matching the right-sized furnace and air conditioner, and will help illuminate the most practical installation course for you to take. **System overhaul** If the heat gain/loss calculation reveals that your existing system doesn't have the capacity to accommodate the new space, and your existing system isn't very efficient, an overhaul may be in order. Evaluate the selection of [high-efficiency systems](https://bc.rodenhiser.com/rodenhiser-blog/upgrading-your-furnace-compare-the-afue-ratings-but-run-the-numbers-too.html) available, which will provide comfortable heating and cooling for the existing home and the addition, while ensuring energy savings. **Extending your system** If extending your current heating and cooling systems is a practical option, you may be advised to install a [zoning system](https://bc.rodenhiser.com/rodenhiser-blog/create-optimal-home-zoning-system.html), along with the plans to extend ductwork. A two-story home is a prime candidate for a zoning system, which is a network of automatic duct dampers that provide customized temperatures to each section of rooms (zones) in your home, ensuring everyone is happy, comfortable and content. **Using a separate system** If your current heating and cooling system is relatively new, but can not meet the extra heating and cooling loads required of the new addition, you could install a new system independent of the existing HVAC system. [Ductless mini splits](https://bc.rodenhiser.com/rodenhiser-blog/ductless-mini-split.html) are ideal in these situations. You’ll save living space and installation costs, since you won’t need to install bulky ductwork. However, you’ll need to ask your HVAC pro if a ductless system can provide enough heat to meet the heating demand during winter.
