Air Conditioners – Deciding Between Room and Central Air Systems
Most homes have air conditioning and home ventilation to deal with the blistering heat of the summer. If you are looking to renovate your home or trying to move into a new one, you might have to make some air conditioning decisions. Read on to find out more about the difference between central and room air conditioners today.
Room Air Conditioner
When you are choosing your air conditioner, you need to consider the area size that you want to cool and dehumidify. You also want to keep your budget in mind.
Room air conditioners usually fit into a window. Some can also be installed into a wall. It is a room unit because that is all it can really cool. This type of air conditioner plugs into an electrical outlet and will not need any special wiring. Larger wall units will require its own circuit, which will require hiring an electrician and a contractor for installation.
A home ventilation system works by sucking in hot outside air and provides HRV moisture control solutions. Through a complicated process, it will then blow in cool air into your room. If you buy too small of a unit, you will have to pay high utility bills to keep it running. Even then, you won’t feel very cool. Units that are too large will cool inefficiently with high humidity levels. This will make you feel cold and clammy.
Evaluate the air conditioner’s power by looking at the British thermal units (BTUs) the device has. The more BTUs mean higher prices and better cooling. Smallest units are around 5,000 BTUs, which only cool around 150 square feet. The largest ones have around 20,000 BTUs, which are able to handle more than 1,100 square feet.
Use online charts to find out how many BTUs are right for your room.
Central Air Conditioner
A central air conditioner will cool your entire house at once. Cooled air is brought into each room then returned back for cooling again. Just like room air conditioners, these are also measured in BTUs per hour. Ask a contractor to calculate your home’s heat gain based on the home design.
Making a Decision
Room air conditioners will cost a few hundred while a central air system can easily go into the thousands. It really depends on your situation. If you are renting or if you only want to cool specific rooms, room air conditioners are better.
If you own your home, it might be better with central air. Make the right decision after conducting proper research.
