We don't just sell equipment, we keep it running at peak efficiency.
Most people only call a heating service repairperson when their heating system breaks down. Yet an ounce of prevention is worth a pound of cure - even with a furnace. The cost of a heating system tune-up varies, but can save 3 to 10 percent on heating costs each heating season.
During the tune-up a service technician should look for two major sources of energy loss in the heating system: incomplete combustion of fuel and high flue gas temperatures. The technician should measure the efficiency of the heating system after the tune-up and provide a copy of the results.
If the combustion gas efficiency is lower than 75% after an inspection, a new heating system may be needed. New system efficiency ratings are typically around 96% and can pay for themselves in energy savings within 10 years.
Combustion Efficiency Testing
- Flue temperature – An excessive flue temperature means too much heat is being produced, thus money is going “up the chimney.”
- Percent carbon dioxide or oxygen – Too little carbon dioxide or oxygen indicates incomplete fuel combustion.
- Smoke number
- Draft – Incorrect airflow limits fuel combustion and uses more energy to move warm air throughout a home.
- Parts Cleaning
A good service technician should take time to clean the following parts of your heating system:
- Combustion chamber
- Heat exchanger surfaces
- Oil line filter
After the initial efficiency test and parts cleaning, the technician should make any final adjustments to the system to keep it running smoothly until the next regular maintenance visit.
The technician should adjust the following:
- Air flow rate
- Fuel flow
- Internal thermostat calibration
Regular heating system check-ups are not only important for efficiency and upkeep, but also for safety. Any fuel-burning appliance that is not maintained properly has the potential to contribute deadly carbon monoxide to a home's air.
