Furnace System Check

A routine preseason furnace system check can help prevent an unexpected breakdown this winter. It is very common for a furnace to experience airflow problems, dirty or clogged filters, ignition control issues, and thermostat malfunctions over time.  Furnaces with cracked heat exchangers could potentially be emitting carbon monoxide. As a result, you could experience poor comfort, increased energy costs, unexpected repair expenses or even exposure to dangerous carbon monoxide. Our PreSeason Furnace system check checklist is designed to help you prevent heating problems this season.

During a system check and furnace, all of the components of your unit are checked and serviced so they operate at peak efficiency. Any elements requiring repair or replacement will be brought to your attention.  We are so confident in our Furnace System Check we are offering a Frost Bite Guarantee.  If something happens to your furnace after we perform the tune-up, we will credit the cost of the tune-up towards any repair or breakdown this season.
