What to Expect When You’re Expecting Commercial Furnace Maintenance

When you have maintenance done on your commercial furnace unit, it should include the following steps:

• SAFETY FIRST! The electrical power to the unit and the unit’s fuel supply should always be turned off before performing any commercial furnace maintenance operations. While the technician will know how to do this, it’s also a good idea to familiarize yourself with these switches and their location and function in case of emergency.
• Clean filters can save your system. Dirty air filters impose needless strain on the heating system and furnace, raise monthly heating bills and can compromise the unit’s operational lifespan. Filters should be checked monthly for cleanness. Pleated filters can be expected to be replaced quarterly unless something is wrong, but permanent filters require monthly cleaning. If your system includes an electronic air cleaner unit, the filter should be cleaned bimonthly. Your furnace filters typically have a slot cover to prevent issues and ensure safety.
• Make sure the thermostat is working properly. The thermostat controls the function of your furnace and should be checked during commercial furnace maintenance in order to maintain a comfortable temperature while keeping energy costs down. Installing a programmable thermostat is another way you can save money on your heating bill.
• Check for obstructions. Vent, exhaust and combustion air pipe obstructions and blockages can cause fire hazards and compromise or prevent proper function of your commercial heat system.
• Check for gas leaks. If you notice an odor of rotten eggs or see damaged or worn connections, you should cut the gas supply immediately. Do not start the furnace until you’ve consulted with a professional HVAC technician. Note: Contacting your local gas company is always a good idea if you smell gas, and some jurisdictions require this by law.
