When it comes to your household's heating and ventilation air conditioning unit, chances are you do not pay it any mind until it starts exhibiting signs of malfunction. Typically, this will occur at the most inopportune times such as when experiencing either extreme hot or cold weather conditions. Here are some of the reasons you may need to enlist the services of a heating contractor.

Clogged air filters

Your HVAC unit does not only work toward heating and cooling the air in your home. It also works toward ensuring there are no impurities in the air that you breathe. As such, the filters will collect dust and grime and will gradually become clogged or blocked. To avoid this, you should schedule the changing of the filters on a regular basis. Not only does this help the HVAC unit work at optimum conditions, but it also ensures that the air in your home remains purified. If your HVAC system has permanent filters, it is pertinent to enlist the services of heating contractor to come clean them out for you occasionally. Having a professional perform this task not only leaves the filters clean but sterile too as the contractors will sanitize the filters and get rid of any bacteria that may start breeding in them.  

Malfunctioning pilot light

A pilot light will be present in an HVAC system that uses gas to operate. If the pilot light has been extinguished, then the unit will not be able to heat your home. On the other hand, it the pilot light is experiencing malfunctions, then you will find that your home is not receiving sufficient heat to suit your needs. A working pilot light will present with a blue flame that is lightly tinged with some yellow. A yellow pilot light indicates that it is on but the heat being produced will not be sufficient for residential heating. If you notice that your pilot light is malfunctioning, it is pertinent to enlist the services of a heating contractor to ensure the problem is fixed before it becomes exacerbated and stops working altogether.

Malfunctioning thermostat

Thermostats will typically be found in electrical HVAC systems. If your thermostat begins to malfunction, chances are your home will be receiving little to no heat. One of the most common reasons for malfunctions is using the wrong thermostat for your specific furnace. Your furnace will determine whether you would need a low line thermostat or would be better off with a millivolt thermostat. A heating contractor can come, determine this for you, and remedy the problem.
