Buying Central Air Conditioning

If you are building a new home, then buying central air conditioning is practically a given. Central heat and air make a home convenient, comfortable, and even safer. Maintaining the temperature you desire is a simple matter of adjusting the thermostat. If you are remodeling an older home, though, is buying central air conditioning even an option? Wouldn't it be too costly to install?

Actually, it is not that difficult to add central air to an older home, so if you have your heart set on buying central air conditioning, go ahead. The job of installation is considerably easier if there is already a system of central heating ductwork in the home. In that case, the new unit needs to merely be tapped in to the existing ducts.

Buying central air conditioning is not unrealistic, though, even if there is no existing ductwork. The installation will take more time and money, of course, but can be done. If you are having it installed, ask that the technicians be creative with disguising the ductwork. It can go through closets, for example, or have specially designed walls built in to hide it when necessary.

The large outdoor unit
that powers your air conditioning will sit outside in a place where air can flow around it. In a packaged central air system, this contains the condenser, the evaporator, and the compressor. When buying central air conditioning, it will be one of your main expenses. It is generally placed near the house's foundation, or sometimes on the roof.

When buying central air conditioning, consider whether you need to install central heat as well. The packaged central air conditioner sometimes includes a system for heating with electricity or gas. With a system like this, you don't have to have a separate furnace housed somewhere.

The ducts are an important consideration when buying central air conditioning. A good portion of the cool air can escape the ducts if they are not airtight. This results in less efficiency and a higher utility bill. Sealing ducts requires more than simple duct tape. It requires using duct mastic, a substance that can be brushed on. The ducts also need to be cleared of any obstructions.
