There are a number of heating and air conditioning problems that occur from simple neglect of your systems. For example, air conditioning and heating costs can double without a noticeable reduction in comfort, and this could be due to refrigerant being undercharged by as little as 10%. Refrigerant should never actually have to be replaced. If you find your unit in need of replacement or augmented refrigerant, chances are very high that this is due to a leak. A leak like this needs to be identified and repaired as soon as possible, or else it will cause permanent failure on your equipment and damage the environment.

Approximately 80% of these issues could be solved by regular unit maintenance.


A dirty indoor and outdoor system could increase your electrical usage by 50% or more. Unrepaired small problems can lead to very expensive repairs or premature replacement of equipment. Depending on the current condition of your equipment this service may pay for itself several times over in energy savings alone. Annual safety checks can eliminate dangerous problems.

For warranty coverage, most all manufacturers require the system to be maintained annually by a licensed contractor; and the owners to maintain written records of all annual maintenance. So, when you become WAM (Walker Annual Maintenance) Plan client, you can expect our highly trained and competent technicians to become completely familiar with you and your air conditioning and heating system.
