Three of the Most Common Heater Problems

November 24, 2016 Todd Hoffman

Your heater can be broken for several reasons. While this list is not a substitute for a technician, who can give you a definite answer about what is broken and provide heating repair for all the problems listed, here are three of the most common heater problems:


1. One problem that occurs is sometimes on a windy day, air will come down through the flue and cause problems with the pressure switch. A lot of these items need to be reset when they are triggered. Some are manually reset, while others electronically reset.


2. Another problem is called a Flame Sensor. A flame sensor’s job is to always sense the presence of fire when gas is going thought the burners and being burned. If it fails to sense this heat, it sends a signal to stop the flow of burner gas so that it isn’t continually pouring out.


3. Often people will describe the problem with their system as “I hear the system trying to come on but it just won’t.” This can often be traced to having a bad igniter. The job of the igniter is to…you guessed it, ignite the gas. Gas pours over the hot surface of the igniter and combustion happens. Some systems will use a sparker instead of an igniter. The sparker will make a lot of audible clicks. The most common brand that uses this is Rheem.



Another common problem that I want to address is the changing of a clogged filter. If your furnace is not blowing hot air, changing a clogged filter might be the answer. However, if you change your filter and then try to fire your system back up, and it doesn’t turn on, don’t keep trying because you can burn out your safety features by repeatedly trying to fire up the system.


Trying to restart a furnace after it has overheated can damage the components inside the furnace that are meant to protect you. When these items no longer function the way they are meant to, you lose some of that protection. Even if your furnace restarts, if you are concerned about the possibility of damage to your system, you can call us and ask for a safety check up on a working system because of what happened (and then explain what happened before your furnace restarted). Normally a safety check up is $89, but mention this page and get a safety check up for only $49.

One more very important issue involving heaters and heater problems is carbon monoxide leakage. Unlike other problems with your heater, you might not even know that carbon monoxide is leaking. Carbon Monoxide is a very dangerous gas. It is a colorless, odorless, and tasteless poison gas that can be fatal when inhaled.


Carbon Monoxide is produced when burning any type of fuel such as gasoline, propane, oil, wood, charcoal etc. It is the product of incomplete combustion. That doesn’t mean combustion isn’t working. It’s just what happens. Because it is colorless, odorless and tasteless, people don’t always know when they are being poisoned by it and breathing it in.


In Residential HVAC systems that use a Furnace (either by Natural gas or Propane), the furnace will exhaust the carbon monoxide and other items through the vent pipe and shove it outside. When there is a problem with your furnace and the carbon monoxide does not completely exit your home, you can slowly be poisoned. The symptoms will be headaches, dizziness, weakness, chest pain, and confusion. If you breathe in too much of it, it will make you pass out or kill you.


If you want to make sure your heater is working properly, we can come out and check the Furnace combustion and heat exchanger systems for proper operation. We are a licensed Heating repair company in the Dallas & Fort Worth area. 682-214-HVAC(4822).


Carbon Monoxide is a silent killer but it can be stopped by having Texas Discount Air come out to make sure your system is operating correctly. If you have any of these symptoms described above then call now for heating repair service.


What if my system is All-Electric like a Heat Pump:


Great question. If your system is an all electric system like a Heat Pump then you do not have a Carbon Monoxide risk with your HVAC system. Make sure your system is not a dual fuel system. Dual fuel systems let the homeowner decide wether they want to run gas or the Heat Pump. Heat Pumps come with their own set of unique problems and actually have more parts, all told. If you have a Heat Pump system that isn’t working correctly, and you live in the DFW area, call Texas Discount Air @ 682-214-HVAC(4822) for heater repair.
