5. Home Evaluation. The contractors should visit your home in order
to properly calculate the correct size and capacity air conditioner
or heat pump you need. Contractors should use a load calculation in
order to do this.
6. Compare estimates. Having more than one contractor visit your
home will allow you to compare the estimates of the contractors. If
one contractor gives you an estimate that is drastically different
from the others, don't be afraid to question them about it. They may
have noticed something another contractor missed.
7. Check for proper license. Make sure that your contractor is
properly licensed. Some states require a license, while others do
not.
8. Get a permit if needed. Call your town clerk to see if you need a
permit for the work you are getting done.
