Need to get some work done on your AC? Schedule the labor for winter and save.

While the costs of whole house air conditioning units can vary from region to region based on labor costs, you will likely be looking at several hundred dollars to several thousand dollars for a serious repair or replacement air conditioning unit.

If you can manage to limp through the summer with an older unit, you can reap quite significant savings on a large project during the autumn or winter, often to the tune of 400 to 500 dollars.

Even better, you'll be providing people with work during a slow season, and help them make it until next summer.

As a bonus, many manufacturers offer rebates on air conditioning equipment during the winter time to encourage sales, so you might even be able to pocket a little cash.
