Regardless of what brand of furnace do you have at your home the most important thing you need to do is understand how it works. No one can fix his problems if he is not even familiar with the principles of the unit. We share here general and furnace repair solutions. You need to look for the following problems and take appropriate measures in order to fix your Furnace (heater). Whether you have a gas Furnace or a standard gas heater, chances are that you have a problem with it. In many cases, you can fix these problems yourself by knowing how your furnace is performing and what common problems you are likely to encounter. This blog post will cover the most common furnace problems and how to fix them quickly. For some furnace issues, you may need professional help.
1. Check your thermostat and make sure it’s on
This may sound silly, but check the thermostat to make sure it is set to “heat” and that it is set at least a couple of degrees above room temperature. You might be surprised how many service calls are made without verification!
Here are some of the thermostat checks you need to do yourself:
Also, check the battery on the thermostat. You may need to replace the batteries in the thermostat. If the thermostat in your home runs on batteries, change them at least once a year or as needed. Some thermostats are connected directly to the furnace and don’t require batteries, while others use batteries. How does it work for you? Occasionally, for those using batteries, the low battery symbol flashes when they need to be replaced.
2. Check and replace the furnace filter if needed.
This is a simple but important part of furnace maintenance. Another of the most common reasons a furnace is not working is a clogged filter. It is also the easiest maintenance job.
Replacing the furnace filter regularly is a quick and easy task that goes a long way in protecting the HVAC system and improving indoor air quality.
Dirty or clogged air filters reduce airflow, making a furnace work harder to circulate. In some cases, a clogged filter may damage the limit switch, which controls the fan.
Test your filter – you can tell if it’s time to change it by lifting it up into the light. If the light does not penetrate, the filter must be replaced. A dusty and dirty smell from the vents when the fan is turned on is another good sign that you should replace the furnace filter.
Change filter – make sure your furnace is turned off. Air should not come out. Check the direction your filter is pointing.
3. Is the furnace switch/breaker switched on?
In case, if your furnace has recently undergone repairs or maintenance work and it doesn’t work for some reason, you can check to see if it has been turned on again. All furnaces have a power switch. Just locate the standard wall switch next to it and check if it’s on or off.
You can also check your furnace circuit breaker or fuse that may have been tripped. Finally, make sure that the front panel covering the fan motor is securely fastened – underneath you will find a push switch that must be turned on fully for your to turn on.
4. The furnace blower runs continuously.
When the blower doesn’t shut off, this is usually an issue with the limit switch. The limit switch tells the blower it is time to shut off. If the blower does not stop, you will need to call a certified HVAC contractor to replace the switch.
5. The furnace is not generating enough heat.
It is possible that the furnace is undersized, and cannot generate enough heat to properly heat the rooms. This also may be caused by dirty or clogged air filters.
6. The furnace is blowing cold air.
Usually, this means the pilot light is out, or the electric ignition is malfunctioning. If the ignition or pilot light is working correctly, you will need to call a professional HVAC for furnace repair.
7. Your furnace is not blowing air at all.
Your furnace’s job is to generate heat, if not. You should try the following steps to fix the problem. First, check to see if the circuit breaker or fuse has blown. … If this does not solve the problem, there may be a problem with the circuit breaker or the wiring. In case if you are unable to fix the issue contact Vese Heating & Cooling for professional furnace repair.
8. The furnace is noisy.
Most furnaces make noise during operation. However, it is important to pay attention to the noise generated by your unit. If you hear rumbling, rattling, or squeaking when the furnace runs, that is not normal.
Grinding sound – This could indicate that the ball bearings are worn and need to be repaired. Turn off the furnace and ask for help to get the job done.
Knocking or rattling sounds – these sounds indicate that something is wrong with your furnace. These can be exposed panels or bolts that need to be tightened. After making these adjustments, the problem should be resolved.
Squealing sounds – This could mean there is a problem with the belt. It may be worn out or in need of replacement. Call a technician to troubleshoot problems.
Let’s say you notice some other unusual sounds. Avoid trying to fix it yourself and seek help from a technician.
9. The pilot light or electric ignition doesn’t light.
The gas furnace can be operated with a pilot light or newer units are typically electronically controlled, eliminating the need for a constant flame.
A faulty ignition system will reduce the furnace’s ability to properly heat the home. Many newer ignition systems are powered by electricity rather than a standing test lamp.
Actions you can take yourself in case if the furnace doesn’t start.
- Turn the furnace power off and on again (the ignition may need to be reset).
- In case if this didn’t work then contact your service representative.
