However, buying energy savers is only part of the game. If they system is installed incorrectly, you will waste money and energy. You will need to find the right contractors to handle the right jobs. But how do you find the right person?

Well, ask around is the first step. Ask your relatives, co-workers, friends, and neighbors to find our whether they have worked with a contractor. Or pick up the phone book, and call and ask for licenses and insured contractors. Make sure ask them whether they have installed the same system before. If necessary, ask them for references if the job is big.

Just make sure the select the right person to handle the right job and install the energy saving systems correctly.

When it’s time for a new replacement, choosing one of the correct size (heating and/or cooling output) is critical to getting the best efficiency, comfort, and lowest maintenance and operating costs over the life of the new system. Some national surveys have determined that well over half of all HVAC contractors do not size heating and cooling systems correctly.

The most common sizing mistake is in oversizing. This not only makes the new system more expensive to install, but also forces it to operate inefficiently, break down more often, and cost more to operate. Oversized heating equipment also often creates uncomfortable and large temperature swings in the house. Oversized air conditioners (and heat pumps) do not run long enough to dehumidify the air, which results in the “clammy” feeling and unhealthy mold growth in many air-conditioned houses.
