If you get the central air conditioner properly installed, then the unit would be firmly sealed and no energy can be squandered, which saves you money. When one talks about saving money with efficient air conditioning systems, the topic of SEER usually comes up. SEER, or Seasonal Energy Efficiency Ratio, rates the air conditioning unit. To keep it easy, the higher the SEER, the more efficient your central conditioning system is, indicating the more money you save, and the more youre saving the environment.
Central air cooling systems have actually been running on Freon for many years, but, this is evidently going to change http://www.bjrefrigeration.com/ . Freon will be replaced with Puron, which is friendlier to the environment. This change is expected to occur no later than the year 2010. Even though the systems would initially cost more, keeping the systems with Freon will cost you much more, as it would be hard to locate the parts if they were to ever break down. Due to the fact that the parts for the older systems would no longer be produced, it would be hard to get them, as they will become quite rare. So in the end, it will most likely save you even more money to get the new cooling system with Freon.
The expense is the one reason many people do not go for central cooling systems. Considering that it needs to be installed first, the cost for the system is more. But, it cools your house quicker, and is not a huge eye sore like the unit air conditioning systems. So you make the decision if you pay a little more, it can give you more benefits.
