For most homes, central heat and air conditioning can be a better choice than using a window unit air conditioner. However, if you can get a good deal on a small unit, or if you have one from when you needed one in the past, it can be a good idea to keep one of these units on hand. These are a few situations in which a window unit air conditioner can come in handy, even if you have a house-wide central heating and air conditioning unit in your home.
1. It's a Great Back-Up
A window unit air conditioner can be a great back-up unit. If something happens to your HVAC system, you can plug in the window unit air conditioner in a centralized area of your home to get some relief until you can have your unit fixed. If your power goes out due to a summer storm, you can also consider powering one of these smaller units with your generator, since it won't require as much energy as a whole house unit.
2. It Can Help with "Hot Spots" in the Home
Do you have areas of your home that always feel a bit hotter than the rest of the rooms in the house? If so, having a window unit air conditioner can be a great way to make up for this. It's also a good option if one family member in the home prefers cooler temperatures than the rest of the people in the house; for example, if one of your kids likes to have a cooler bedroom, a window unit air conditioner can allow him or her to enjoy this added comfort without causing the rest of the family to have to deal with a change in temperature.
3. It Can Work in Rooms without Air Conditioning
If you add on to your home, you may not want to install a whole new unit that is large enough for your add-on, or you may not want to pay for the duct work and other added expense to tie in that part of your home to your central unit. This might be especially true if the room will not be used very often, such as if it's a spare bedroom or an office. In these situations, a window unit air conditioner can provide AC when it's needed.
As you can see, a window unit air conditioner can be a handy device, so it's not a bad idea to keep one on hand in the home.
