Telltale Signs You Need a Heating Repair – Part 2

This is the second part of a two-part article. Be sure to have read the first part before proceeding below.

Signs Your Heating System Needs to Be Repaired

In the previous article, we discussed the most obvious signs that your heating system needs to be repaired. Below are some of the signs that you may have not noticed or that you may not realize are telling you to get your heating system repaired.

7. Switching On and off Intermittently

Most heating systems are programmed to turn off at the point when the room has reached its ideal temperature. However, this cycle should not happen often with short intervals in between.

If you feel like your system is turning off and on again constantly, then it is no longer the thermostat doing its job. Rather, this signifies a malfunction in your system. This is often caused by the exchangers overheating, which will turn off the system and then start up again when they cool down.

8. A Yellow Pilot Light

Pilot lights on your furnace should only be blue to mean that it’s working fine. Any other color like orange, yellow, red, or any other color pilot light means there are too many condensates in your furnace. This will hinder the efficiency of your system, and at the same time, it is also harmful for your health.

9. Decrease in Air Quality

This is often a sign that not many people realize. If your home starts to become stuffy, humid, or hazy all of a sudden, you should immediately call a professional to check your heating system. Brushing it off is not only bad for your heating system, but it could be dangerous to your health.

10. If You Haven’t Gotten Your Heating System Checked in a While

Many people neglect getting their heating system checked, especially if they feel like nothing is wrong. One of the best ways to prevent any major issue is to identify the root of the problem before it gets bigger. It is always best to have your heating system inspected at least twice a year—ideally before you start using it strongly in fall or winter, and after winter when you are using it less frequently.

What Should You Do If Your Heating System Suddenly Stops?

If your home’s heating system suddenly stops working, it can be a stressful and potentially dangerous situation. It’s important to take the right steps to ensure your safety and comfort while you wait for a professional to repair the system. Here are some tips on what to do if your heating system stops working.

1. Check the Thermostat

The first step is to check the thermostat. If the temperature isn’t set correctly, the system won’t turn on. Make sure the thermostat is set to “Heat” and the temperature is set higher than the current room temperature. If the thermostat isn’t the problem, try resetting the circuit breaker.

2. Evaluate the System

If resetting the circuit breaker doesn’t work, it’s time to evaluate the system. Check for broken or loose wires and other signs of wear and tear. If you can’t find the problem, it’s time to call a professional.

3. Call for Professional Help

If the problem is beyond your expertise, it’s time to call a professional. A certified and experienced technician will be able to diagnose the problem and make the necessary repairs.

4. Stay Warm and Safe

Until the technician arrives, you’ll need to find a way to stay warm and safe. Wear multiple layers of clothing and use extra blankets to stay warm. If the temperature drops below freezing, it’s important to take extra precautions to protect your home, including turning off water to the home and disconnecting outdoor hoses.


There are several signs that indicate you may need to get your heating system repaired. These include your heating system making strange noises, not heating your home evenly, or your heating bills suddenly increasing. If you notice any of these signs, it’s important to call a professional to come take a look at your system and make any necessary repairs.
