1- Thermostat: Make sure it's ON (Furnace not turning on)

Some times the problem may be caused by just simple situations. Check the thermostat to assure it is set on "heat". The set must be at least five degrees above room temperature.

Here are some few thermostat checkpoints:

A: Checking the battery if your home's thermostat unit runs on batteries. It is a good idea to change the batteries once a year.

Other thermostats are wired to the house’s electrical system and don't use batteries.

B: Double-check the programmable mode to make sure the date and time are correct and it is not on timer mode.

C: Open up the thermostat cover and make sure no dust or debris has sealed it.

D: Verify that the thermostat is set to "Heat" Then, try moving the temperature degree arrow up and down to see any noticeable change.

 

2- Try to Reset Furnace Circuit Breaker (Furnace does not work)

There is a chance that a circuit breaker or fuse was tripped or blown.

In your home’s breaker panel look for the circuit that controls the furnace. Turn off and on the breaker once or check the fuse and keep it in the "On" position.

 

 

3- Gas Line Problem  

In front of the furnace, follow the gas line and make sure is not shut off.

By checking the hot water tank and see if it is working you can make sure if may have a gas supply issue.

If you smelling gas make sure you proceed with caution. Leave the room and contact your local gas company immediately.

 

4- Check and Change Your old Filter (Furnace is not making enough heat)

In the cases of poor-performing furnace and situations that furnace is working but not making enough heat in the home, you need to make sure the air filter is clean.

How to Check and Change Furnace Old Filter

One of the simplest and easiest ways to maintain the air quality and air force of your furnace is changing the filter.

  • Locate the filter - Most commonplace of filter location is between the furnace and air intake vent.
  • Inspect the filter - Check the filter and make sure if you can see the light through it. A weak airflow also may indicate a dusty filter and its time to change.
  • Replace the filter - Turn off your furnace. Make sure you check the airflow arrows on the filter before replacing it.

 

 

5- Inspect Your Vents around the house

Examine all the vents around the house to ensure nothing is covering or blocking them. Also, you may need to check the return air vent to make sure it is not blocked.

Furniture or toys may be preventing the openings of vents, stopping heat flow.

 

6- Watch the Burner Flames

You may need to regularly check your burners to make sure they are free from debris and contamination. Make sure burners are clean and the way to do this is to look at the flames. They should be blue and even.

In the cases that flames are yellow, probably burners are dirty. You can clean the burners with a vacuum cleaner. Turn the power and the gas off first before you do the vacuum.

It is a very good idea to maintain and service your furnace yearly and the best and safest to do this is to ask a licensed technician to take care of it. You can rely on Alliance Energy Source licensed technician's deep understanding of how your furnace works to service your furnace or boiler.

 

 

7- Furnace Blower Works Continuously 

A continually operating furnace that doesn't turn off indicates the furnace needs repair. Make sure the thermostat is not set to “continuous fan”.

Turn down the temperature to see if it makes any difference. If it doesn't work call your local HVAC service technician.

 

8- Furnace Does Not Blow Air 

There is a small inspection window on the furnace. Look into it and make sure the blower is clear of any debris.

Second check the green and red flashing lights. Green means furnace is okay and if you see the red light you need to call for service. In the case of no light, the furnace problem may be caused by one of the following: thermostat, the run capacitor, the blower motor, furnace control board or transformer.

 

9- Check and Clean Debris from Intake & Exhaust Vents

Some furnace uses intake vents from outside of the house. Clean them regularly and make sure nothing is blocking the intake or exhaust.

In the wintertime, ice may be clogging one of the pipes, clean them and if still not working call for service.

Furnaces are designed to work for many years, but running forever. If your furnace unit has passed the manufacturer’s warranty period, it might be the time to replace your heating system.
