As long as your home stays warm, you may believe that your central gas heating system is functioning the way that it should. Unless the heat goes out, you may not give a second thought about its condition.
However, even if the unit is able to keep up with your household's demands, there could still be a problem that needs to be fixed by a professional. Below are a couple of signs that there is an issue with your home's heating system of which you may not have been aware.
1. Condensation Suddenly Starts Forming on All Windows in Your Home
One sign that there is an issue with your home's gas furnace is when you start noticing that condensation is forming and remains on all of the windows in your home. This is especially true if you have never had an issue with excess moisture before.
When there is excess moisture caused by your home's furnace, this typically means that the exhaust is not being properly vented out of the system. Usually, this is caused by a blockage either in the chimney or within the furnace itself.
Since the exhaust is not venting properly, it travels back into your house and creates excess moisture. Because this exhaust also contains carbon monoxide, have a repair technician find and fix the problem as soon as possible.
2. System Has Started Running Constantly Without Any Breaks Between Cycles
Another indicator that there is a problem with your home's heating system is when it starts to run constantly. Even when it does shut, it starts back up again within a few minutes.
When your furnace runs constantly with little to no break, this puts a strain on the unit and can cause it to wear out faster than normal. This issue could be caused by a malfunctioning condenser. Or, especially if there is condensation is present, there could be a blockage that is trapping air inside the system, which sends false signals to the condenser and causes it to keep switching on.
If your heating unit is causing condensation to form on all of your home's windows and/or is starting to run constantly, there may be a blockage within the unit that needs to be located and cleared out. Or, the system's condenser may be malfunctioning. In either case, you will need to have someone inspect the system to diagnose the issue. Contact a heater repair service to schedule a time for them to come out and take a look at the furnace.
