The tune-up of the furnace is done when the temperature starts to decrease. Furnace tune-up in Buffalo NY is mostly done by professional contractors. Tune-up of furnace increases comfort and save money by reducing power and gas consumption. Experts recommend to tune-up your furnace once a year for proper functioning. In this article let us discuss some of the things that are done during furnace tune-up.
The air conditioner is tested:
The air conditioner is used to circulate the air in the house. When the air passes the air conditioning unit the refrigerant of the air conditioner cools the air and it is then circulated into the house. The working cycle of the air conditioning unit is disturbed if there is some problem in the unit. In that situation, you can easily identify the problem and fix it with the help of a trained and professional technician.
Calibrate the thermostat:
Poor communication between the thermostat and the furnace may affect the performance of the furnace. If the thermostat setting is not communicated with the furnace unit then the furnace will not work as per our settings. Ensure to calibrate the thermostat to ensure whether the furnace is receiving the communication properly and working as per the settings.
Inspect the gas pipe and valve connection:
If there is leakage or blockage in the gas connection then it may affect the performance of the furnace unit. It is also very dangerous since it may damage and even end up in the death of people. So these elements must be inspected to prevent breakage and damage.
Check the ignition of the furnace:
The fuel for the furnace is provided by burning the gas. To start the burning process the gas needs ignition. If the furnace cannot ignite the gas then the furnace cannot create the heat. So during the furnace tune-up, the technician will check the timing and the force of the ignition process.
The temperature rise of the furnace is checked and also recorded:
The temperature of the furnace depends on various factors like the size of the area in which it is used, the age of the unit and the temperature setting. With all this factor consideration the furnace must achieve the desired temperature at a particular time. The temperature rise is used to identify the performance of the furnace if there is some issue with the temperature rise then it can be identified and also rectified during the tune-up of the furnace.
Clean and adjust the burners for improving the efficiency of the furnace:
Dirt in the furnace can reduce the efficiency of the furnace. So clean and readjust the burner to achieve the maximum efficiency of the furnace.
Clean the flame sensor of the furnace:
The flame sensor in the furnace is used to ensure that only gas is entered into the furnace when the flame is ready to start the ignition process and burn the gas to provide the fuel needed for the furnace to work. If the gas enters the furnace during other times it gets accumulated which is very dangerous. The work of the flame sensor is to switch off the furnace if it doesn’t detect the flame. The flame sensor fails to detect the presence of flame when it is very dirty. So that the flame sensors are cleaned during the tune-up process for the proper functioning of the flame sensor and the furnace.
Check the controls for safety purpose:
Failure or wrong functioning of controls reduces the efficiency of the furnace and also it is very dangerous. So the technician will check all the control and their desired operations.
Check for gas leakage near the furnace:
Gas leakage near the furnace area is very risky and it can even damage the property. So during the furnace tune-up, the technician will check the whole pipe from the start to the end for leakages.
Adjust and lubricate the blowers if needed:
The blower assembly is used to circulate the warm air inside the house. To maintain the efficiency of the furnace the blowers must be adjusted periodically and lubricate the blower parts if needed. The blower is one of the important parts in the furnace and it must be maintained properly.
Test emission of Carbon monoxide:
When carbon products are burnt in the oxygen environment gases like Carbon monoxide is produced. It is very toxic and harmful to the persons who are inhaling it. The filters of the furnace prevent the emission of carbon monoxide. So the filters must be always kept clean and replaced if needed.
Airborne pollutants are blocked from circulation by the air filters during the air circulation process. So it must be cleaned and replaced regularly.
Primary heat exchanger:
Without direct contact between two gas or liquids, the heat from one gas or liquid is transferred to another gas or liquid with the help of the primary heat exchanger. The primary heat exchanger will allow only the heat and not the gas out of the furnace. This process is the primary way of circulating heat in the house.
Secondary heat exchanger:
For better efficiency, the furnace has two heat exchangers in it. The secondary heat exchanger is very small in size and it is very risky when compared with the primary heat exchanger.
Combustion air intake and exhaust pipe:
For burning and ignition oxygen is very necessary. Combustion air intakes allow the oxygen into the furnace to start the burning process. Extra emission during the combustion is collected and sent out through the exhaust pipe into the vents. As part of the furnace tune-up in Buffalo NY, the technician will check the entire process.
The function of the furnace and the communication to the thermostat are done using electricity. So proper functioning of the furnace the electrical connections are checked by the technician during the maintenance process.
Circuit boards, blower assembly, draft inducer assembly, condensate drain line of the furnace and the fan used in the inducer assembly are also checked, cleaned and reinstalled if needed.
