If you have recently invested in an addition to your home, you could be wondering about the best way to heat and cool the area. You might not want to alter your existing heating and air conditioning system for just one room or small portion of the house, and luckily, you shouldn't have to. Instead, consider these alternative heating and cooling options that can keep this new part of your home nice and comfortable without affecting the rest of your HVAC system.

Consider a Ductless Heating System

One excellent option for heating your home addition is to install a ductless heating system. As the name suggests, no ductwork is necessary; instead, the system is more similar to what is often found in a hotel room. It's great because it allows you to keep the room at a separate temperature than the rest of the house. For example, if your add-on is a guest room, you don't have to worry about heating it with the rest of the house; instead, you can heat it only when you are planning on having a guest over, and your guest can then control the temperature to his or her liking.

Use a Window Unit Air Conditioner

For the summer months, a window unit air conditioner can be a good option for an add-on. The more modern window unit air conditioners can do a great job of cooling a room or other relatively small space, particularly if you purchase a large enough unit. Newer window unit air conditioners also typically have air filters, so they can condition the air much like a central heating and air conditioning system can do. Although it might not be the ideal choice for cooling an entire home -- particularly in an area that experiences high temperatures during the summer months -- it can work well for smaller areas.

Consider a Space Heater

If you aren't yet ready to install a ductless heating pump system, another option is a space heater. Space heaters are typically used for supplemental heat, but if the add-on is small enough or if the temperatures aren't too low in your area during the winter, they can do a surprisingly good job. Plus, you can always move the space heater from room to room, so if you don't need to heat the add-on, you can use it elsewhere in the home.

As you can see, there are various options for heating and cooling your home addition without affecting your existing HVAC unit. These options are good ones to look into if you don't want to tamper with your existing HVAC system.
