What Happens During a Furnace Repair Appointment?
You can also schedule routine maintenance appointments with Quick Temp technicians. Then we can enter your home and evaluate your system. We will be able to identify minor concerns at this point before they become significant issues. This preventive care can extend the life of your furnace and help it work more efficiently over its entire existence. But what happens during your HVAC repair appointment?
Examination of the System
Your HVAC specialist will examine many aspects, including the cleanliness and operation of your interior and outdoor components. This inspection involves inspecting the heat exchanger, blower motor, and other details. They will also ensure that your pilot light, thermocouple, or hot surface ignitor is clean and working correctly. Finally, they will ensure that your electrical connections, cables, and circuits are in good working order.
Your air conditioning system contains several components that must be cleaned regularly. During your maintenance visit, your HVAC specialist will clean the condenser and evaporator coils. They’ll also change your air filters, clean the fans, and clean the exterior and inside unit cabinets to keep your system running smoothly.
It is natural for your furnace to see wear and strain over time. However, wear and tear loosens screws, stretches belts with time, and de-lubricates components such as ball bearings. Your HVAC specialist will adjust these components and, if necessary, refresh your refrigerant. Finally, they’ll straighten bent fins and lube joints and inspect your thermostat to guarantee it’s detecting the temperature appropriately.
What Are the Parts of a Furnace?
You know that your furnace keeps your Skiatook, OK, house warm when the outside temperature drops, but do you know how it works? A furnace system comprises several components that generate heat and distribute it to indoor living areas. Our skilled HVAC technicians will discuss fundamental furnace terminology with you to help you become more comfortable with the components of a furnace system.
Furnace System Components
In older furnaces, the pilot light runs continuously, ready to ignite the gas when the furnace is turned on to begin heating.
The thermocouple detects a lighted pilot light. When the thermocouple detects a lighted pilot light, an electrical signal is sent to the gas valve, telling it to open for gas flow.
Hot Surface Ignitor
Hot surface ignitors, a newer technology, replace pilot lights in modern furnace types. When the gas supply is turned on, an electrical current is delivered to the ignitor, boosting its temperature and causing combustion to begin.
The flame detector is a safety device that detects heat generated by the hot surface ignitor. If no heat is detected, the gas supply is turned off.
The gas valve
The gas valve is a device that regulates the pressure of natural gas entering your home. It is suitable for use in the furnace. It also holds the flow of gas to the furnace.
The burners of a furnace combine gas and air to create a flame, which serves as the furnace’s heat source.
This component is made out of a long metal tube. The heat exchanger collects harmful gases produced by fuel combustion. While the heat exchanger emits heat into the surrounding air, gases are properly evacuated away from your house.
Motorized draft inducer
The draft inducer motor starts before the gas in the furnace begins to burn. It has to create a vacuum to assist drive hazardous combustion gases out of your home’s vent pipe.
The pressure switch activates the draft inducer motor, which pushes fumes through the vent pipe. The draft inducer motor’s vacuum pushes on the diaphragm of the pressure switch, starting it and allowing gas flow. If the pressure switch does not feel the vacuum, gas is not let into the furnace.
The blower motor must move the heated air produced by the furnace through the duct system and into the house.
Blower Motor Capacitor
This component starts the blower motor and may keep it running at a constant speed.
The Limit Switch
The limit switch monitors furnace temperatures. The limit switch shuts off the gas when the furnace becomes too hot.
How Does a Furnace Work?
In a gas system, the following components of a furnace work together to provide heat:
- The pilot light, which is also known as the ignition system, illuminates the burners within the combustion chamber.
- To generate heat, the burners consume fuel.
- Heat enters the heat exchanger and passes to air, raising the temperature to the setting specified by your thermostat.
- When the air reaches the proper temperature, the blower propels it through the ductwork in your home.
- Warm air escapes from vents and into your living rooms.
How an Electric Furnace Works
DIY: Furnace Air Filter Replacement
You should replace the air filter in your furnace at least once every three months. Ideally, it would be best if you replaced it every 1-2 months. Pleated filters often last a little longer, but they produce a more considerable pressure drop in the system; ensure that your furnace is built to handle this.
Non-pleated filters have a shorter lifespan but do not impede as much airflow. Non-pleated filters are used in many older HVAC systems not built for severe pressure reductions.
First, turn off the electricity to change the air filter in your furnace. Remove the filter access panel from the ducting once the heater has fully turned down. Next, gently remove the old filter, ensuring no dust or dirt falls off or spreads elsewhere.
Remove the old filter and replace it in the filter compartment. If the filter includes arrows, ensure they point in the same direction as the airflow from the furnace.
