5 Reasons You Need An Annual Furnace Tune-Up - Air Assurance

Top 5 Reasons for Furnace Maintenance Tune Up

Top 5 Reasons to schedule your annual furnace service with Air Assurance and stay ahead of any seasonal breakdowns. Neglect is the number #1 reason why mechanical system fail.

Energy Savings - With the system clean, filter changed, gas pressures set correctly….it can mean the difference in your comfort and the performance on your utility savings during the fall and winter months.

Safe Operation - AC clean and check service is all about efficiencies. But the furnace check is all about safety. Safety from fire. Safety from Carbon Monoxide potentials and more.

Early Detection - You don’t wait until you have a flat tire on the highway to buy new tires right? When you notice the tread wearing and the tire becoming bald it affects performance. Stay ahead of any potential break downs this season.

Optimize Performance - Our technicians will use a combustion analyzer to determine how efficient you furnace is operating….and we can make adjustments to make sure you get the best performance.

Peace of Mind - We check over 25 items during our heating and furnace check to give you comfort and peace of mind.

Furnace Maintenance

The furnace burner is the heart of your central heating system. It’s the component that mixes air with natural gas and produces a clean-burning, high-temperature flame that generates heat for the whole house. A clean, intact furnace burner also ensures maximum fuel efficiency and low operating costs while minimizing the amount of combustion byproducts, including dangerous carbon monoxide. Here are some details about the process:

The Burner Cycle

In a typical gas-fired furnace, heating and burner operation are divided into several stages:

• Signaling for Heat. When the household temperature drops below the thermostat setting, the furnace receives a signal to initiate heating from the system thermostat.

• Fuel Delivery. The furnace fuel valve opens to start the flow of natural gas to the burner. At the same time, air from the furnace air intake blends with gas flow to provide the right mixture for clean, safe ignition and combustion.

• Ignition. The mixture of natural gas and air is ignited at the burner. Ignition may be provided by a pilot light — a small flame that runs continuously — or, more commonly in newer furnaces, by an electric igniter that produces a spark.

• Heat Transfer. Heat produced by the burner enclosed within the combustion chamber is added to the HVAC system's airflow by the heat exchanger. This vital component incorporates air passages to transfer heat efficiently to the airflow while sealing out dangerous gases.

• Heated Air Circulation. Heated air is pulled into the ductwork by the system blower and distributed throughout the house and into each individual room through supply air vents.

• Burner Shutdown. When household temperatures reach the desired setting, the thermostat sends a signal to shut off gas flow until temperatures drop again and the heating cycle repeats.

Furnace Burner Maintenance

Checking the burner is a critical part of annual furnace maintenance by a qualified HVAC contractor. The technician can verify proper burner operation by sampling and analyzing combustion gases. The burner in a gas furnace may require professional cleaning at intervals to support efficient and safe operation.

How Does a Furnace Flame Sensor Work?

Furnace flame sensors are a critical heating safety component. This device verifies that the main furnace-burner flame has ignited properly after the thermostat signals for heat. The electrical signal from the thermostat opens the gas valve and an electronic igniter lights the burner. If every step in this process functions correctly, then the furnace produces heat safely.

However, if something goes wrong and the burner fails to ignite, unburned natural gas could continue to flow, escaping into the house and posing a serious safety hazard due to potential fire or explosion. Read on to learn how flame sensors prevent that from happening to keep you safe.

Flame Sensor Basics

• The flame-sensing rod that reacts to heat extends into the furnace burner. The sensing rod is connected to the furnace's electronic control board.

• The control board receives a signal from the thermostat and opens the main gas valve, then actuates the electronic igniter that lights gas flowing into the burner.

• If the burner flame ignites, heat produced by the flame is detected by the sensing rod. The control board allows the gas valve to remain open, and heat is produced safely.

• If the sensor does not detect the burner flame, the furnace control board shuts off the gas valve immediately.

Potential Flame Sensor Issues

Sensor-detection function can be affected by a number of issues, most of which are related to the age of the component. A frequent telltale symptom of a failing sensor is that the furnace "short cycles." It starts up properly when signaled by the thermostat but then almost immediately shuts down again. The furnace will not continue running beyond a very short time.

Common causes of sensor failure include:

• Cracked, bent, or broken sensor rods

• A dislodged sensor rod

• Carbon residue on the sensor that is degrading heat-sensing capabilities

Annual furnace maintenance by a certified HVAC technician helps prevent sensor problems, as well as detect and diagnose a failing sensor.
