Thru Wall Fan

What do you think would be better through the wall a / c or central. a power of good will launch me $ 7200, with new duct work, ect attic fan. adding through wall units probably less than $ 2,000. Finances are tight, but this house is our home for at least 20 years older. Central adds value, but it is worth the cost of the renovation work and it will take for the future value

I prefer to have central air. This adds value to the house. Moreover, the whole house is cool all the time. Not just a few rooms. We must also add the amount it costs to cool the house in both directions in the long run your total cost.

Yeah, central air conditioning is expensive to implement - especially in older homes.

But they are far more effective than the window of an air / c central and saves money on energy bills too. In addition, your home is cooled at the same time and is much quieter.

You can look in the new type of air conditioning units that has room, but a central cooling. He does not need ducting, controls a single room, and I think it is more efficient than window units.

Central air conditioning is money, but most definitely better. And the little building stinks, especially if you have drywall and paint. Have you considered mini-split systems where the condenser is located outside the lines and coolant run into a fan in the house. They are very effective and can also be used to produce heat. These systems are very popular in Asia and Europe. The addition of an attic fan will always help.

Yes, central A / C is so much better than the wall unit.
With wall unit, you'll need to get fans through the cooling air circulated in the house. Listening to them, and tripping over the wear on you quickly.

The central chugs a v. long nice and quiet, cooling and drying air. It is much more efficient too, as the large wall unit will run 4x as much to accomplish the same reduction in temperature. With the Central, there will be no hot spots and cold either.

Wall units "filter should be cleaned several times a season. Central air conditioning will need its filter cleaned or replaced once a season, and outside the unit should be cleaned in the spring, and covered for winter .

$ 7200 is on the low side, talking about their references.
