Benefits of a furnace inspection
Some HVAC experts say up to 75 percent of no-heat calls in the winter are related to a lack of maintenance. Left unserviced, a furnace can stop working suddenly, leaving your family in the cold.

It can also be a health hazard. Technicians say a furnace inspection can reveal carbon monoxide leaks, which are hard to detect because the gas is colorless and odorless. Carbon monoxide can lead to headaches, dizziness, nausea and even death. An estimated 500 people die each year, and 15,000 people are taken to emergency rooms, because of exposure.
