Furnace Inspections

We test and evaluate all heating systems

First | Previous Picture | Next Picture | Last | Inspection Gallery

When we run a furnace there are a lot of things we look at besides if it gets warm. All combustion appliances are inspected for proper venting of exhaust gases. We use sensitive equipment that can detect among other things exhaust leaks, propane, natural gas and other gasses. A few of the other things we check are

filters
age, estimated lifespan
burners
heat exchangers
