Your homes heating system is made up of essentially different components one is the heating sensor or thermostat. This piece measures the temperature inside of the home environment and determines when the temperature needs to be increased.
When the room's temperature decreases the thermostat tells the heater it is time for the blower to turn on. The ignition in the heater creates heat that is distributed while the furnaces blower moves the air throughout the ductwork and distributes it into the house. The cool air in the room is cycled into the return ducts that are placed throughout the house and is warmed. This warm air out, cool air in sequence continues until the temperature in the room is the temperature requested and then sends an indication that the furnace can shut down.
Something to remember is that HVAC furnaces are mechanical systems. This means that they need to be maintained in order to continue to work at optimal performance. It is so important that a tune-up is done by a professional HVAC technician to maintain your heating system.
When a furnace expert is out to complete a tune up on your heating system the first thing they will do is take a look at your furnace. Professional furnace repair technicians will look for soot and residue around the furnace. They will follow this by inspecting the furnaces thermostat by increasing the temperature. This will allow the furnace to ignite and allow the technician to check out the flames within the burner. The technician will check to ensure the flame is steady and burning blue. If the flame is orange, yellow and/or flickering this can be an early indicator that the furnace combustion is not adequate.
The next step your Home Performance Solutions technician will undertake is to turn the thermostat down to let the furnace cool down. They will turn off the circuit breaker to the furnace and continue to examine the interior components. Once the system has cooled the technician will remove the sides of the furnace and suck out the accumulated dust and debris from the system. They will then use a clean, damp cloth to continue to clean the system. A rag can be used to clean the blades of the fans and blowers. While the sides are off this is when oil can be added to the shaft to keep things moving as they should be.
If your furnace has a belt the technician will check to ensure there are no breaks or splits in the belt. They will also ensure the tension on the belt is correct. If there are any cracks within the belt or if the tension has become loose the belt will be replaced. Once all of this has been completed the furnace is ready to be put back together and the circuit breaker can be turned back on.The last thing that the technician will do is put a fresh filter in and remind you that it is good practice to change your furnaces filters once a month during the heating season. It all seems so simple however should be left up to the professionals. A HVAC contractor is licensed and trained to work inside the complex heating system. In the long run it save you money have the professional do the job right the first time instead of coming out to fix your mishap. You won't be sorry and you will make up the expense in the money you save on your monthly heating bills.
