What do you do when your furnace breaks down in the middle of a frosty Wisconsin winter? What if you turn your unit on and instead of releasing heat, it blows cold air?

Whether your furnace is fairly new or not, things can go wrong that can lead to no heat situations. You wouldn’t want your heating system to completely fail when you need it most!

While some issues can be resolved by doing a few checks and making a few adjustments, it is still recommended to have an HVAC professional inspect your heating system. A reputable heating company in Menomonee Falls and Brookfield WI, such as New Berlin Heating and Air Conditioning, can help you save time and money while keeping you from spending unwanted time in the cold.

Below are some of the most common reasons why your furnace may not be working as it should.

An Overheating Furnace

A clogged filter causes your furnace to overheat. Dust and filth restrict the airflow, causing your furnace to work harder and run longer to meet your home’s heating needs. This problem cannot be overlooked as recurrent overheating will damage the heat exchanger, which is an expensive component to repair or replace. Replacing the dirty filter with a new one usually solves this issue. Once the airflow to the furnace is clear, it will be less likely to overheat and should work effectively.

A Malfunctioning Thermostat

The thermostat is a good place to start whenever you experience troubles with your heating system. Oftentimes, people assume that their furnace is defective without first taking a look at the thermostat.

Check the thermostat and confirm it is set to “HEAT” and not “COOL” or “OFF”. Also, the fan must be set to “AUTO”. Then, check if the thermostat is set to a temperature high enough to allow the furnace to release heat.

If you fail to pay attention to your thermostat, chances are it will cause the furnace to blow cold air. In checking the thermostat, ensure that your thermostat has fresh batteries installed.

Dust and dirt usually cause the thermostat to show inaccurate temperature readings. If you have an older thermostat and discover that it is dirty, use a paintbrush to clear off the dirt and see if it works again. If you notice any corrosion on the thermostat, remove it with an electronic contact cleaner.

Make sure that the thermostat is free from heat sources, such as cooking appliances and direct sunlight.

Damage to the Ductwork

Your furnace produces heated air which is transported throughout your home via ducts. If you have a leak or any form of damage anywhere within the ductwork, the air that will come out is going to be weak or cool instead of warm.

Small openings such as cracks and leaks may pick up cold air that mixes with heated air, causing your furnace to fail to provide your desired temperature. Heavy damages to the ducts can even result in completely losing heated air.

When it comes to ducts, it is best to have a qualified technician mend the damaged areas. Also, regular maintenance can help preserve your ducts and avoid costly repairs.

Dangers of Dealing with Faulty Gas-fired Furnaces

Leaks within the heating system can cause indoor air to become contaminated. A faulty flue vent can cause the reversal of emissions inwards to the house instead of transferring polluted air outside.

Carbon monoxide and methane emissions can cause serious allergic reactions and certain respiratory diseases, such as asthma.

In addition to these dangers, trying to fix a faulty gas-fired system can lead to electrical shock, explosion and fire. It’s always recommended to have a professional HVAC company work on gas furnaces.
