How to Predict a Boiler, Furnace or Air Conditioning Failure

Every mechanical system, like a furnace, boiler, air conditioning, HVAC and heating system are made from small mechanical parts that move and coordinate with each other, controlling, cooling and pushing and compressing on the same or a different schedule all to provide you with a conversion of energy from one form gas, electric or steam to a different form such as hot air, hot water or cold air.

It is the nature of every machine that runs, moving and non-moving parts a getting old and every different manufacturer has a time period until maintenance and repair starts to be needed.  Parts may be a blower, thermostat, thermo-coupling, regulator, contactor, capacitor, switch, main board, sensor, transformer, resistor, motor, fan, valve and other electronic devices.  All these have a different  time period and a lifetime and it depends on the number of hours that you run the boiler, central air or cooling system, the maintenance you have performed, and the pressure the system is under will determine the condition and lifetime and the amount of repairs that will need to be done.

There is No Smoke Without Fire.

  • Moving mechanical parts are well manufactured in today’s world with precision technology.  The first sign that something is going to break is when something makes an unusual noise or vibrates in an abnormal way.
  • Systems under low pressure, or in case of a hot air central air heating and cooling system the air pressure is not strong enough or is coming slow from the diffuser exits walls and ceilings, are also a sign that something will break down soon.
  • A system that is running constantly with no stopping, on and off, it may be a simple thermostat problem or it might be a bigger problem as the heat or cool air is not enough or exposed to the room well enough so the room temperature in your home or even another area, like a living room, dining room or kitchen or in your building, it may feel cold in the winter or not cool enough in the summer.
  • Lights that are dim or blinking.  Look at the light bulbs every time the your cooling or heating system turns on or off, that might be another sign of overload or other possibilities such as a breaker problem or problem within the electrical high voltage unit.
  • Water that is leaking from any of those systems.  Look for a marks, water marks on the ceiling or the floor, walls or in the central air systems and boiler or furnace within the body and heat exchange and pipes, a hot water boiler or steam boiler with no water will create damage in the boiler and crack the boiler and the only way to repair it is to install a new boiler.
  • A longer than normal delay in starting, more than 5 minutes shows electrical problems within the compressor or heat pump in air conditioning, or an electrical problem in the boiler or furnace that needs to be fixed immediately before the boiler or furnace will stop working completely.
  • Anytime you touch a device and you feel an electrical spark, that is not only a problem that is very dangerous.  Any motor, blowers, air handlers, compressors, heat pumps, should be grounded and well protected from a surge.

If you are not an air conditioning technician, as most people are not, just give us a call and we would be happy to fix these problems before the system shuts down and you need to deal with emergency air condition or heating repair.  Please feel free to call us 24/7 or in an emergency with any questions or for any advice.
