Don’t Take Heating Maintenance Lying Down.
Lower your utility bills. Catch an unwanted furnace breakdown before it happens. Avoid unsafe furnace or boiler operation. And keep your furnace manufacturer’s warranty active with annual furnace maintenance.
Manufacturers know a furnace can degrade 3% per year.
When components start to degrade your system works harder to produce the same result. Stresses caused by dirt and neglect during the thousands of starts every year cause parts to wear out. Worst yet, your furnace life shortens.
The truth is your furnace is a dirt collector.
- Real dirt you can see and some things you cannot see, but that you definitely need to know about. Dirt compromises how well your system can perform.
- A furnace also forms rust over time, fittings get loose and electrical components weaken after starting thousands of times.
- In fact, 80% of all HVAC repairs could have been prevented with routine heating system maintenance. That’s one reason why manufacturers reserve the right to void your warranty.

Furnace maintenance checklist.
- Blower Door Safety Switch – Prevents the fan blower from operating if the door is opened.
- Fuel System Inspect, Test.
- Gas Valve – Adjusts heating output based on demand.
- Gas Pressure – Measure rated and actual gas pressure.
- Gas Leaks – Inspect for potential threat of fire or explosion.
- Gas Burners – Dirt, rust causes poor combustion, increases monthly utility bill up to 15%. Brush the burner surface to break off hardened pieces of dust and rust while vacuuming.
- Proper Combustion – Must be adequate and from a safe source.
- Combustion Air Inlet – Enables air to reach the burners.
- Combustion Condensation – Water vapor produced during combustion.
- Flame Sensor – Safety control turns gas valve/burner on-off.
- Ignition System – Ignites gas burners; weak part can shut down system.
- Transformer – Power regulation required for safety, efficiency. Changes the voltage of the input power to a different voltage for use within various furnace systems.
- Pressure Switch – Safety control shuts off power to igniter if it senses negative pressure created by the draft inducer motor. Also guards against gas leaks and prevents the furnace from cycling if there’s a mechanical failure. Test for proper operation.
- Heat Anticipator – Fine-tunes the point at which the thermostat turns off the furnace burners. For example, if the furnace is cycling on and off too often this may be the cause. Calibrate to proper setting.
- Electrical Connections – With the furnace starting thousands of times a year, loose wiring can short out the heating system. Inspect for safe operation.
- Thermostat Operation – Can cause breakdown and waste energy. Low-voltage thermostats are powered by a transformer that reduces the incoming line voltage from 120 volts down to a level between 12 and 24 volts, depending on your furnace.
- Blower – Once your furnace heats the air, the blower motor is responsible for turning a fan to circulate that warm air out of the furnace and into your home. Blower ensures your home reaches your thermostat temperature setting.
- Blower Capacitor – Works like a battery. It stores the extra energy needed to kick the blower into action. Check Rated and Actual amps.
- Blower Temperature Sensor Control Safety Switch – Controls when the blower runs or turns off depending on the air temperature within the furnace. A high limit setting turns off the burner if the furnace overheats to dangerous temperatures.
- Blower Motor & Bearings – Can cause no heat. Clean, lubricate.
- Blower Motor Volts-Amperage – check rated and actual amps.
- Blower Wheel, Blower Belt – Can cause motor breakdown. Inspect for any sign of damage.
- Combustion Inducer Blower or Combustion Fan Ventor – Draws air through the furnace’s combustion passageway to improve efficiency and to allow thorough heat transfer. A well maintained combustion inducer blower extends the life of the furnace. Clean, test.
- Air Temperature Rise – Lowest recommended temperature rise and the highest allowed temperature rise through the furnace. This is usually a 30° difference, shown in a range like 50-80° or 45-75 °
- Heat Exchanger – Age can cause cracks leaking deadly CO gases into the air. Critical part of your furnace. Responsible for heating the air, but it can be dangerous if not cared for properly. Inspect heat exchanger for critical cracks, wear.
- Flue Condition/Operation – Removes excess toxic gases thru vent. Inspect.
- Air Stream Seal – Inspect access opening into duct system.
- Return Plenum Sealed – Stop costly air leaks. Inspect.
- Air Filter Type & Condition – Dirty furnace air filter stresses your furnace, wastes energy and cause furnace to shut down. Inspect.
Lastly, if your furnace is dirty what is your duct-work like? Open an air vent. Use a wet, white paper towel and wipe ductwork to see exactly how dirty. We can clean your air ducts too. Call for air duct cleaning and save $100.
