How do I choose a contractor?

Some states require contractors to be licensed.  Check with your state government, and if the

state requires licensing of air conditioning contractors then make sure the contractor you use
has a license.

Make sure the contractor pulls a permit.  A good contractor will have no objections to pulling
a permit, and with a permit you will have the benefit of a city or county inspection.  If a
contractor tells you that you do not need a permit, check with the local building dept.

This is a big purchase, so I recommend you get at least three estimates.  This may take a little
work but it will be well worth it.

Before the contractor you choose begins work make sure you get it in writing.  Be sure you get
the warranty in writing, not just for parts but also for labor.   Usually, the parts are warranted by
the manufacturer while the labor is warranted (if any) by the contractor.

And, don't forget!  Dirt is the biggest enemy of your air conditioner, and a good air filter is the best friend!  Giving your air conditioning system an efficient, high MERV rating air filter is the best thing you can do for your air conditioner.  A good air filter will extend the life of your air conditioner because the important parts, like the blower assembly, the cooling coil, and other  inner parts will stay cleaner, operate more efficiently and last longer.

And, as a side benefit of having a good air filter, your family and you will enjoy breathing much healthier indoor air.  Air that will be free of dustmites, mold, mildew, dust, pet dander, etc. etc.
