What is included in a routine maintenance call?

We are often asked “What is included in a proper routine maintenance or service call?”  It’s hard to convey over the phone, but like any experienced trade, we rely on years of experience to know the sights, sounds, feel and even the smell of your equipment.  But to ensure we cover everything, there are a number of items we check, adjust, or clean to ensure your system is operating efficiently and safely.

The BC Safety Authority regulates the installation of gas equipment in the Province, and they recommend homeowners have all gas fired appliances regularly maintained to operate efficiently and safely.

“Annual servicing recommended Have your home heating devices serviced annually to prevent tragic fires and reduce the risk of carbon monoxide poisoning which can cause death.   Natural gas, propane, oil and wood burning appliances that are not operating correctly produce carbon monoxide an odorless, tasteless toxic gas. Basic symptoms of carbon monoxide poisoning are: headache, nausea, dizziness, shortness of breath and confusion. You may also decide to have a CSA-certified carbon monoxide detector installed in your home for added protection.”  – Source – BC Safety Authority

This is what they recommend a qualified service company should be doing on each regular maintenance call, and as a result it is what we do:

Intermediate or major service levels

Sometimes, as a result of the condition of the equipment, we are required to do more extensive service and that may result in more time and more cost to you.  If we determine the level of service is anything other than routine, we will identify the reason and discuss this with you prior to proceeding.  At all times, we are required to ensure the safe operation of your equipment and we can not allow the continued operation of unsafe equipment or in unsafe conditions.
