Sizing and installing your new Central AC

If you are installing or considering buying a new air conditioning system it is important that the equipment is customized to fit your home since each home has different needs (i.e. size of house, sun exposure, configuration of the house etc.). The installation techniques and sizing of your new system will make a dramatic difference in the function, comfort and energy savings of the new air conditioner. It is critical to hire a highly trained professional to properly install your new air conditioners

Here are the elements your contractor needs to evaluate before installing the system. The information comes from the Energy Star Web Site:

1. Calculation of the size of the equipment- a good contractor will not solely rely on the square footage of your house or assume the original equipment was sized properly. To properly size your homes air conditioning equipment your contractor needs to evaluate how much heat your house loses when it is cold and how much heat it gains when it is hot. The latter being especially important in the Orlando area due to the searing summer heat.

2. Seal and insulate the duct work in attics and crawlspaces- If your new system is going to give you maximum output and save the maximum amount of electricity, it is critical that the system be sealed. Ask your technician to check and seal all of your duct work. A good contractor will be able to test and repair your air ducts. He may find that you need to add or reconfigure your duct system

3. Check and correct airflow

4. Proper refrigerant charging- A recent field study reported that 75% of all installed air conditioning equipment may have the incorrect amount of refrigerant. Incorrect refrigerant levels could result in lower energy efficiency (5%-20%) and cause component failure. There are 3 methods, depending on the manufacturer to verify correct refrigerant levels. Ask your contractor how they verify the correct refrigerant levels. Technicians are required to be certified to handle refrigerant. Make certain yours is.

5. Equipment Placement-For optimal results your contractor will follow manufacturer’s guidelines for placing your equipment. While all homes are different here are some basic rules:

• Indoor equipment should be stored in a conditioned or insulated space.
• Outdoor air compressor should be placed out of the sun and clear of debris.
• Equipment should be installed in a space that is accessible for maintenance.
• Thermostats should not be placed in direct sunlight, drafts doorways, skylights and windows.
