Keep your home’s heating and cooling system running smoothly
Maintaining your furnace and air conditioner is an important step toward maximizing energy efficiency in your home, and can also prolong the life of the various components in your heating and cooling system.
Furnace Maintenance
Make sure you’re ready for winter by scheduling a clean-and-check with us. Annual service can improve your furnace’s efficiency by up to 10%. To ensure that your heating system is operating safely, we check for evidence of dangerous carbon monoxide emissions and other problems. A thorough cleaning of your heating equipment also improves the circulated air quality within your home.
Our 20-point annual clean-and-check for natural gas furnaces includes:
- Remove burners and pilot assembly. Clean and inspect for cracks and rust.
- Check thermocouple and replace, if needed.
- Clean flue passages, check flue pipe for rust holes and good seal at chimney.
- Check draft and chimney passages for obstruction.
- Inspect heat exchanger for cracks and holes.
- Vacuum combustion chambers.
- Inspect exposed wiring and connections.
- Inspect and test blower assembly.
- Replace air filter (if supplied by customer).
- Vacuum blower compartment.
- Relight and adjust pilot height, check pilot and main burner safety. Cycle on burner and check and adjust flame pattern. Check high-limit operation.
- Level wall thermostat and check calibration.
- Cycle furnace to check for normal operation.
Air Conditioner Maintenance
Most people want to beat the heat when summer arrives. You can count on us to keep your home comfortable. Failing to properly maintain your air conditioner can decrease its energy efficiency by as much as 30%. It’s important to have your air conditioner professionally cleaned and your refrigerant level checked each year. With Nicor Home Services, you’ll be able to operate your air conditioner more efficiently, reducing the amount of electricity you use.
We also use a comprehensive checklist to perform air conditioner maintenance. The list includes:
- Start system, check suction and discharge pressures.
- Inspect and clean condenser coil. Replenish up to 2 lbs. of refrigerant (if needed) at a reduced or no cost.
- Lubricate fan motor, if applicable. Check for bearing wear.
- Remove electrical control panel and inspect all exposed connections. Check connections to compressor terminals.
- Inspect exposed tubing for kinks or oil leaks.
- Check blower operation.
- Replace filter (customer supplied).
- Blow out condensate drain line.
- Check for oil leaks at exposed evaporator fittings.
- Start system and recheck pressures and check amp draw.
