If you are getting a central air conditioner, then it may be best for the unit to be placed on the roof. Here are some of the things you should consider before deciding whether it would be best for the unit to be installed on the roof instead of on the side of the house:
1. What is normal for your area
A look around the neighborhood will let you know what is normal for the area. In some areas, it is more common for the unit to be installed along the side of the house. In other areas, it is more common for it to be put on the roof. In most cases, it is a good idea to go with what appears to be the status quo. If your area seems to be split with about an equal amount of units on the sides of houses and on the roofs, then you'll want let the next few considerations help you reach a final decision.
2. How much room is available around the house
Some homes are on large lots where space around the home's exterior is not an issue. However, there are other homes that offer extremely limited space around the exterior of the home. If this is the case in your situation, then installing the unit on the roof means you can have the air conditioning where it'll free up some of your precious space.
3. How much foliage you have around the exterior of the home
Something you need to think about when it comes to the housing unit is ensuring that the unit's vents aren't blocked so they can allow air to come inside. When you have a lot of foliage around all the sides of your home, this poses potential problems because it means a lot of debris can get inside of the AC unit where it can cause a lot of problems in the motor. For example, little twigs can end up causing problems for the fan or for the belts. Also, a lot of dust can be blown right off the leaves into the housing unit.
When you decide to have the air conditioning unit installed on the roof, the installation will likely require the use of a crane that will be used for the lifting of the large unit, so it can be placed on the roof. Contact air conditioner cran lifting services to take care of this for you.
