If you feel that your electric bills have been too high lately, you might be thinking about replacing your air conditioner. However, there are some ways that you can dramatically increase the efficiency of your AC without buying a new unit. For instance, your insulation could be the root of your problems. More specifically, your home might be made out of some materials that are very poor insulators, such as metal.
One of the most common reasons for an inefficient air conditioner actually has very little to do with the appliance at all. Instead, you might have some bad insulation on your hands. Insulation can naturally wear down over time, or your house might simply be made of materials that are very bad insulators. The first thing that you should check is whether or not your home has a lot of metal components on the exterior.
Metal Conducts Heat
If you have metal in either your doors or your roof, then you might have found your problem. Metal is a great conductor, which means that it can conduct heat into your house during hot summer days. On top of that, metal roofs and doors can become quite dangerous to touch, which can lead to quite a bit of discomfort if you need to open up a metal door that is exposed to the sunlight.
The biggest problems will come from areas of your house that have a lot of surface area and act as good conductors. This is usually going to mean your roof and your garage door, both of which are capable of conducting a ton of heat.
Garage Doors and Roofs
If you do have a metal roof, then changing the material or adding an extra layer of insulation to the interior might be a good idea. If you live in an urban environment, then a green roof can be particularly appealing, both as a way to reduce the amount of heat that enters your building and to reduce your environmental impact.
If you have a metal garage door that is directly exposed to the sun frequently, then you might want to consider an overhang or some other protective structure that could prevent the door from heating up so much. Getting a replacement is also an option, with composite and wood garage doors being much better at insulating your home. Composite will generally be cheaper and require less maintenance, but the aesthetic of an authentic wooden door can be quite appealing to many homeowners.
If you survey your home and find that you don't have a problem with heat-conducting materials, contact a company like Metro Air because perhaps it is time to get your AC fixed.
