unsure about how you should handle it, you’ve come to the right place for a
guide on how to fix the issue. Here are some of the most common causes and solutions
to your gas furnace problems.
Checking the thermostat can help you identify the problem
first thing you can do before kicking into panic mode is checking the
thermostat. Usually, if you’re the heater in your gas furnace is not turned on,
the fan will still keep working and you will feel cold air coming through the
vents. Once you check the thermostat, you will notice that that the settings
are slightly different. And so, in the event that the thermostat setting reads
“On”, change it to “Auto” and you should be getting warm air in no time.
However, if the thermostat is on “Auto” and you are not getting warm air from the
air vents, then you will need to try out other solutions.
Clogged air filters and overheating will require ac repair &
gas furnace has a limit switch on it. The switch as a safety precaution in the
event that your gas furnace overheats and you are at risk of starting a fire.
Therefore, once a temperature threshold is reached, the switch turns off the
burners. Similar to the “On” setting on the thermostat, despite the burners,
turned off, the fans in the gas furnace keep on running and so you end up with
air that is not adequately warm.
is often the result of neglect. Due to irregular and improper maintenance of
gas furnaces, their filters and other associated components quickly become very
dirty. Eventually, with the grime building up over time, the airways are
clogged. Because of this, the gas furnace needs to work much harder for
extended periods to provide the same amount of heating it would have it the
airways have not been blocked. Therefore, with the continued stressful operation,
the gas furnace overheats turn off, and you are left with cool air coming
through your vents instead of warm air.
problem can be easily solved with regular AC maintenance & repair. If the
filters fitted into your system are cleaned regularly, or replaced once they
are damaged, they will not clog up the airways and restrict airflow.
Furthermore, vents that are contaminated with stagnant dirt and bacteria can
cause respiratory problems and dust allergies. If family members in your home
are more susceptible to allergens, you might want to play closer attention to
your central ac unit,
and ensure that it gets the proper ac repair services it requires to stay
operational at peak efficiency.

step to remedy your problem.
Ignition issues are common among gas

off, verify if you do indeed have an ignition problem on your hands by checking
the pilot light of your gas furnace. If it is not out, then our problem lies
elsewhere. However, if it is out, you can do two things. First, check the user
manual of the gas furnace and find the instructions that point out how you
should go about relighting it. Follow the instructions carefully and relight
it. Then, wait a few minutes to see if the pilot light goes out again, or stays
lit. If it stays lit, then you are lucky, and your problem is solved. However,
if it goes out, you will need to call in professional help to come and adjust
or even replace the pilot light. It is important to remember that any attempts
at trying to fix the problem on your own without any expertise will likely make
the problem worse than it is, and you might have to end up paying a large some

hire the best AC maintenance & repair professionals you know and have them come look at your system.
another case, if you cannot relight the pilot at all, you should check your gas
supply to ensure that the valve is actually switched on. This is another safety
mechanism to ensure proper operation. The gas supply turns off if you have a
dirty pilot light. Clean it up well yourself, or hire ac repair services to get
the system back to proper gas flow.

heating process and get it away from the gas furnace, thereby reducing the
chances of you ending up with molds in duct. However, with time and irregular maintenance runs, the drains

burners. Therefore, hire professionals right away to come and have a look at
your system, get the drains cleaned out, and get it back in working order.
