The Advantage Plan

Service is needed before the start of each cooling season and each heating season. Different maintenance procedures are performed for your cooling system than for your heating system. Because your comfort system works so hard during the year, a number of components need adjustment, calibration, lubrication, and cleaning each year. Your system will still work for a time without maintenance, but not as efficiently.

During an inspection, a number of items are checked. Some of the checks are to identify and stop small problems that could become big problems. Some are to verify safe operation.

When it comes to your family you want dependable air conditioning and heating systems that provide you with value as well as comfort. You can expect both from McWilliams Heating, Cooling and Plumbing because we’re not comfortable until you are! Ask about the Advantage Plan.
