Fall is here and with that brings cooler weather. Is your furnace ready? When talking about furnace maintenance, standards and procedures vary from company to company. When having your furnace inspected annually by a certified technician, the checklist may include:
- Vent system to be checked for blockage and/or leakage.
- Combustion gases to be analyzed.
- Blower access door to be checked to confirm a tight seal at the furnace.
- Fresh air intake to be checked for blockage.
- Heat exchanger to be inspected for corrosion or rust.
- Burners to be checked for proper ignition.
- Drainage system to be checked for blockage and/or leakage.
- Blower wheel to be checked for debris and cleaned if needed.
- Amp-draw test to be performed.
- Wiring to be checked for corrosion and/or damage.
- Static air pressure checks, gas pressure testing, and temperature rise checks to be performed.
- Filters to be changed. (This should be done by the homeowner more frequently than annually).
Not all HVAC companies or technicians perform all of the above services. When receiving a quote for the maintenance, ask what all the service includes. Furnace manufacturers all recommend annual inspections and maintenance by a qualified technician. They also state in their warranties that damage to the units caused by improper maintenance is not covered under warranty. This does not mean that an annual furnace check-up is required, but it is recommended to avoid the chance of voiding the warranty.
