How to diagnose a furnace problem

If you are having problems with your furnace, there are a few steps you can take to diagnose the issue.

The first thing to do is check the thermostat. If the temperature is off, the thermostat may be defective and need to be replaced.

Next, make sure that the blower motor is working by turning it on and off. If the furnace isn’t blowing cold air, the motor may be broken and will need to be replaced.

Finally, check for power related issues by checking for outlets in various parts of the house, turn on all of the lights in one room and see if they all turn on, and try to start up the furnace from inside.

If you are still experiencing problems, please call our office for a consultation.

How to fix a furnace problem

If you’re having trouble with your furnace, there are a few things you can do to determine the problem.

1. Check for leaks. Inspect the roof, seams, and joints where the metal ductwork meets the wood frame of the furnace. Look for water damage or signs of leakage around fan blades, registers, or other important components.

2. Try diverting heat from other parts of the home by closing off vents near windows and doors. This will force the furnace to work harder and hopefully identify any mechanical problems.

3. If all else fails and you suspect a bad motor, replace it as soon as possible to avoid serious heating problems in your home.

If you’re still having trouble, contact a professional.


If you’re having problems with your furnace, it’s important to take a look at the roof and see if there is any water on it. A problem with the furnace could mean that water is getting into the machine and causing damage.

Other signs that might indicate a problem with your furnace include an unusual smell or noise from the unit, inability to heat up your home, or red flags in the wiring. If you notice any of these signs, it’s important to have a professional come out and check out your furnace for you.
