It is cold, and your heating system heating your home properly. Now, you are looking for answers to how to get the heat flowing again. You came to the right place. Start by calling us 24/7 so we can dispatch one of our technicians.
Your heating system works by creating heat and pushing it out into your home. Simple.
It generates heat by burning gas or propane in the combustion chamber. This heat warms up the heat exchanger.
When the heat exchanger reaches the right temperature, the circulating fan turns on. That forces are through the heat exchanger, warming it up. It then pushes the warm air out into your home. At the same time, it draws cooler air from the house back through the return duct to warm it up and keep the cycle going.
Now it is time to start looking at the fixes. There are two primary reasons your heating system is not working. Either there is a lack of airflow through the system, or the system is not producing heat. Here is how to check both. (continue below)
Why Choose DOC Heating & Cooling?
Lack of Furnace Airflow
Low airflow is probably the easiest problem to solve. Even knowing that the solutions can range from simple to complex.
First, double-check your vents, ensure they are open and unobstructed. With the circulating fan turned on at the thermostat, check to see if you are getting much airflow through the duct system.
If not, something is restricting the flow. First, check your filters. Clogged filters are a very common problem and often result in low flow through the system. Include this in your regular furnace maintenance schedule.
If your filters are clear, there may still be something restricting the flow. Any further restrictions are not as easily fixed and are best handled by a properly trained and equipped professionals.
The other airflow problems typically relate to the circulating fan not running or needing cleaning. There may be a restriction in one of your ducts as well, such as excessive dust, something dropped into the vents or even a rodent nest. You could also have a restriction at the heat exchanger lot allowing air to flow through. A professionally trained heating technician should handle both of these furnace repair jobs.
Any of these are best left to a professional to solve.
Furnace Not Producing Heat
If you are getting airflow through the vents, then check the temperature of the air. It may be not heating at all or may not be as warm as you desire.
The very first thing to check is your thermostat. If you have not changed the batteries recently, you may want to try doing so. Be sure the temperature is set appropriately to signal the system to start. The batteries should be a part of your regular furnace maintenance plan.
Starting at the beginning of the process, as many issues could lead to your furnace not heating the air in your home. Another fairly common issue is the pilot light blowing out. This is a small flame that burns all the time so that when it is time for the burner to light, there is a source of heat already ready. There are several reasons why a pilot light could go out, so you want to be sure you find the reason to ensure it will continue to work again in the future.
Some systems do not use a pilot light to light, but rather use an electric ignitor instead. These warm up when it is time to light the burner, allowing the gas to flow and light. These are very delicate and are best left to a professional heating technician to diagnose and replace.
There could also be a fuel flow issue, with a problem with the valve controlling fuel flowing into the combustion chamber. No fuel means no heat.
Also, a little less common is a problem with the exhaust fan. Most systems include sensors to indicate if the exhaust fan is working properly. If not, it will prevent the ignition and burning systems from starting. This safety feature prevents a dangerous buildup of toxic gases in your home.
In addition to these, there is the brain of the system. This includes a control board and a series of sensors, relays, and switches. If one of these malfunctions, it will prevent the system from generating heat.
