The Bigger the Unit, the Better

AC units are carefully sized to the amount of cubic feet they need to cool. That’s particularly important when purchasing a new AC unit or renovating your house. If an AC unit is rated for a smaller space than you have, it will work too hard to cool the air, wear out more quickly and struggle to meet the demands of the thermostat.

If the AC unit is rated for a larger space than you have, it will constantly turn on and off, wearing itself out and growing undependable over time. Pay attention to capacity and pick the right unit for the space you have.

Better to Let an Air Conditioner Run Until It Quits

The initial cost of replacing your AC unit is high, but that doesn’t mean you should avoid a new purchase. Don’t make the mistake of keeping your old air conditioner long than you should. An old air conditioner will perform poorly, cost you more money in repairs and eventually become more trouble than it’s worth.

If your AC unit is 10 to 12 years old or older, investing in a newer, more efficient version will save you money and aggravation over time.
