Whether it's a heat pump or a gas furnace, homeowners rely on their heating system to keep them comfortable during winter. That said, the heating system must be maintained accordingly to ensure it works efficiently when you need it the most.
Repairing or replacing the heating system during winter can be a nightmare for most homeowners. To ensure the heating system works accordingly, heating and cooling experts recommend looking out for the following signs that indicate repair is needed:
1. It Makes Unusual Noises
If your heating system makes banging, screeching, rattling, and other weird noises, it can be a warning sign that something is wrong. Most heating systems will make small sounds when running. However, any loud or unusual sounds should be checked and assessed by heating system professionals.
When you hear unusual noises coming from your heating system, a loose or worn down part can be the likely culprit. It is also possible that a belt needs to be replaced. The sooner the system is checked, the better your chances of fixing the problem before it becomes a costly mess.
2. Your Have Poor Indoor Air Quality
Do you find yourself (and your family members) constantly sneezing or coughing when you are at home? You might need to check your heating system. If the furnace is not working accordingly, it can release dust, allergens, and other harmful contaminants into the air.
Changing your heater's air filter is one effective way to reduce indoor pollutants. However, if you have changed the filter and you don't notice any improvements, you need to have your furnace checked. Service technicians can examine the system to check if there are other problems that need fixing.
3. Constantly Operating or Short Cycling
Short cycling happens when the system keeps turning on and off for brief periods. Short cycling can be caused by a malfunctioning heat exchanger. If your heating system continues to operate for a long time without turning off, it can indicate something is wrong and should be checked by a professional.
4. Abnormal Pilot Light Colors
If you are using a gas-powered furnace, you should check the pilot light if you suspect something is wrong. Ideally, you should see a blue flame. If the flame is orange, yellow, purple, or red, it is a sign that the furnace is not working accordingly.
Often, abnormal pilot light colors are caused by rust (and other harmful compounds) in your furnace. When not removed by professionals right away, it can reduce the heating system's operating efficiency.
5. The Fan is Not Working
If the system's fan is not working, you must check if the thermostat is set correctly. If the answer is yes, you need to check the air filter next. If the air filter has not been replaced in ages, it can prevent the fan from working properly.
You can also check if the breaker switch is off. If not, try turning it off and on. Ensure you don't flip the switch too quickly, as it can cause an electrical fire. It would be best to have a professional check the problem to play safe.
6. You Notice a Burning Smell from the Heating System
Noticing a burning smell is normal when turning on the furnace for the first time. The smell can be attributed to accumulated dirt and dust. Usually, the burning smell will go away in a few minutes.
However, if the burning smell lingers, you need to check your furnace filter as it might need to be replaced. You can also unplug the system and vacuum out the dirt and dust. If the problem remains, it's time to call the professionals.
7. Cool Air Comes Out of the Vents
If you notice cold air coming out of the vents, the problem can be caused by a leaky duct. However, there are other possible causes as well. You can troubleshoot the issue by checking your thermostat. Check if it's set to "Auto" instead of "Fan On." If not set accordingly, the fan can blow unconditioned air.
8. The Boiler is Leaking
Boiler leaks are often caused by problems with the internal components like the pump seals or the pressure valves. If the problem is with the latter, the boiler will have an elevated pressure. The former, on the other hand, occurs when the seal has been worn out.
Leaks found around the pipe can be caused by either improper installation or corrosion. If the system is not installed correctly, there is a chance you will be advised to get a new boiler. In similar cases, it would be best to have the system checked by a professional, as they can provide the best recommendations for your case.
Final Thoughts
If you notice one (or more) of the warning signs above, get in touch with a professional immediately. Early detection and quick action can often prevent costly replacements and help ensure you stay comfortable during the cold months.
