The ‘click’ sound that a furnace makes when it switches on is satisfying for furnace owners. But all the satisfaction goes down the drain when your furnace does not generate heat, and the house remains dead cold. Now, what can you do?

A malfunctioning furnace is extremely common. You can contact any of the leading HVAC contractors in Severna Park to fix your furnace. If you want to check your furnace yourself, here are some troubleshooting tips that you can checklist before contacting a professional for help:


Your thermostat decides what the house temperature should be. It instructs the furnace of the right temperature, and the house warms. However, if your thermostat does not detect the desired temperature, your home will either remain cold or become scorching hot.

Both situations are problematic for you. There are two solutions to this issue. First, check your current thermostat regularly for its batteries and wirings, and contact your technician accordingly. Second, if you do not have the time to give your current thermostat, install a smart thermostat that will understand your temperature requirements after a few days and control the furnace accordingly.


The breaker supplies the main power to the furnace. Sometimes, the breaker trips due to voltage differences. The tripping of the breaker protects the furnace from damage due to excessive current flow.

Go to the circuit and check the breaker. If it has tripped, you will have to replace it with a new one. Ensure to buy the right size breaker or ask your technician for furnace repair in Severna Park.


Check the furnace switch if the breaker is functioning well, yet the furnace does not light up. The switch should be near the furnace and easy to locate. Ensure that the switch has no breaks or tears on it.

Air filters

Air filters are an extremely important part of the furnace. Filters ensure that the indoor air is free from allergens, bacteria, viruses, dirt, dust, and pet hair. Moreover, air filters create a smooth airflow path from the system to the house and vice versa.

If the air filters are dirty and clogged, the indoor air quality will significantly fall. Also, the system will have to work harder to push the air into the home due to blocked paths. If you do not clean your air filters regularly, they may force the system to break down due to excessive working.

Flame Sensor

As the name suggests, the flame sensor senses the flame and helps in lighting up the furnace. If the flame sensor is faulty or dirty, it will not function properly and cause the whole system to suffer. All you need to do is clean the flame sensor and put it back in its place.
