When one talks about saving money with efficient a/c systems, the topic of SEER normally comes up. SEER, or Seasonal Energy Efficiency Ratio, rates the air conditioning unit. To keep it easy, the greater the SEER, the more efficient your central conditioning system is, meaning the more money you save, and the more youre helping the environment Their Site .
Central air cooling systems have been running on Freon for a long time, but, this is apparently going to change. Freon will be replaced with Puron, which is friendlier to the environment. This change is supposed to happen 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 made, it would be hard to get them, as they will become very rare. So in the end, it will probably save you more money to get the brand-new cooling system with Freon.
The expense is the one reason many individuals do not go for central cooling systems. Since it has to be set up first, the cost for the system is more. However, it cools your house quicker, and is not a huge eye sore like the unit a/c systems. So you make the choice if you pay a little more, it can give you more benefits.
