A furnace is an important part of your heating and cooling system, more specifically the heating part. Furnace repair and maintenance is as much important as AC maintenance & repair. So, taking it Furnace maintenance and repair is not something to take for granted.

Here are some tips on Furnace repair and maintenance from HVAC specialists –


Tips on Furnace repair & maintenance

1.      Keep track of the performance

If and when the furnace repair is needed, you know what will be helpful to the HVAC technicians? The performance log of your furnace. That’s why it is suggested to keep track of the repairs you went through.

For example, if the blower fan has troubled before and it is troubling again, the AC repair or Furnace repair guys will be more efficient in their jobs if you can provide him the details of previous maintenance issues. So, keep track of the performance and notify the HVAC system technicians about them.


2.      Regular inspection of Pilot Light or Electric Ignition

By regularly checking you can prevent heat loss since these faulty components can have an adverse impact on the performance. Note that, flickering or yellow pilot light indicates that the Carbon Monoxide level is high in your Gas Furnace.


3.      Check the alarms & detectors every once in a while

Since Carbon monoxide is colorless and odorless, there is no solid way to detect carbon monoxide without any detection device. For alarms and detectors like these Carbon Monoxide ones, regular checkups are absolutely necessary for furnaces.


4.      Turn off the exhaust fans in Bath, Kitchen and Other rooms

Many people leave the exhaust fans open without any good reason. They think leaving them turned on helps the environment in the house. But they don’t realize the truth.

When you leave the exhaust fans turned on, the heat is compromised. So, when you are done with cooking, turn off the exhaust fan. Same goes for the bathroom exhaust fans. Don’t keep it on for more than 20 minutes after you are done using the kitchen and bathroom.


5.      Look out for odd smell and disturbing noises

One very common way to know if the furnace is broken or not is by observing the sound it makes. When you notice the rattling sound, high pitch noise, it is an indication that it’s time you got your furnace checked up. Besides the noise, the smell can give you a hint. If you smell a rotten egg type smell, this means the gas is leaking from the gas furnace.


6.      Keep the chimney clean

A clogged chimney is a sign of disaster. Not only does it make heating and air conditioning less efficient but also cause the Carbon Monoxide level to rise. Remember, your furnace flue ventilates the toxic gases. That’s why it is an absolute must that the chimney is clean & free from all types of obstructions like bird nests, squirrels mess or the heavy deposits of soot. 


7.      Check the safety features

Every once in awhile, deliberately trip over the safety limits so that you can check they are working properly. This way, you will be prepared for the actual emergency.


8.      Lubricate all the moving parts

It is important that all the moving parts of your furnace are moving without any restriction. That’s why they should be properly lubricated from time to time.


9.      Check the electric wires and panels

One of the major problem people face regarding their furnaces is the wiring malfunction or electrical panel faults.


10. Clean & check the gas burners

Clean components equal clean and fresh air. That’s why the gas burner of your gas furnace should be cleaned or checked regularly.


11. Check the pilot assembly

While you at the gas burner it is also suggested you check the pilot assembly for better performance and longevity of your heating system.


12. Clean & check the thermocouple or the flame source

The thermocouple or the flame source that actually ignites the furnace should also be checked. This way, you are not wasting your time fixing it when you actually need the heated air.
