After you get the central unit installed properly, it will be sealed tightly so that energy cannot be wasted. This will help to save you money. Once someone talks about saving money from efficient air cooling systems, the SEER topic usually comes up. SEER stands for seasonal energy efficient ratio. It rates the central air system.
Basically, the higher the A SEER rating the more efficient the air system. You can enjoy saving money while doing your part to help save the environment.
Freon has been the refrigerant used in central units for many years, but this changed in 2010 when Freon was switched out with Puron. Puron is environmentally friendly. These systems will cost a lot to begin with, but keeping up with the Freon systems will end up being very expensive too in the long run.
Freon systems will also be hard to repair since it will start to be hard to find parts for them after they break down. The parts for these older systems will not be manufactured anymore, so finding the right parts will be a challenge. It will probably be a lot cheaper in the long run to go ahead and get the new cooling system.
The expense of a central cooling system usually turns people off. It must be professionally installed and it costs more to purchase a central unit. A central unit does cool your home faster and it is not a bad eye sore like other air conditioning units. Take your time and make the best decision for your needs. You may have to pay more, but it could be the best choice for you. Compare the cost to install central air conditioning with all of the benefits.
