Solve problems with central heating
1. If the heater fails to start verify the fuses at the main service panel. Look for blown fuses or tripped circuit breakers.
2. If the air flow from the heater isn’t as efficient as it used to be, check the air filters. Any obstruction it the way of the air flow will cause the system to work less efficient. If the filter is too dirty replace it with a new one, or try to clean the old one.
3. Check the compressor unit from outside. There may be something obstructing the air flow such as vegetation growing excessive or some object falling into the unit stopping the fan from rotating. Eliminate any obstructions from the way and check if there are any damaged blades. Damaged blades should not be repaired, but only replaced as they affect the entire performance of the system.
4. Another issue affecting the fan is ice. Check to see if it has frozen and try to add some lubricant to it if you notice it moves hard.
5. Verify the fan belt tension. Look in the owner’s manual for the appropriate slack the belt should have when pressed down. Depending on the result loosen it or tighten it.
7. If you have a gas system, check the pilot light if it still burns. Adjust the flame to maximum if it won’t stay lit. For further problems consult a professional.
