Why Minneapolis Furnaces Leak

Just like any machine, furnaces can run into issues. If your Minneapolis furnace has any ongoing issues, contact your heating and air company, like Twin City Heating and Air. One of the most common issues is water leaking from the furnace. There are many reasons why your furnace could be leaking, but we would not suggest fixing it yourself to avoid any future problems with your furnace. However, you can find out what is wrong. Here are some of the most common problems that cause leaking water.

Condensation Leak

Condensation leaks are the most common issue if a furnace is leaking water. High efficiency furnaces commonly have this problem because they have two heat exchangers. This helps produce more heat, but it will also make more condensation. If the pipes carrying the condensation clog up or leak, the water will leak under the furnace instead of out the floor drain.


Humidifier Leak

A whole home humidifier helps your home not get too dry, but it can also leak if there is a clog or break in the water line. Those are the most common reasons for a leak in the humidifier, but there are others that should be checked out before making a conclusion.

Clogged Filter

Clogged air filters limit the amount of air that can go to the coils. Without warm air going to the coils, they often freeze. Water then leaks out the furnace and onto the floor. This one is easily avoidable if you change the air filter according to the directions with the air filter.

Cracked Heat Exchanger

The heat exchanger is the main part of your furnace, so a crack can mean a lot of issues. This is the most expensive repair and can be a reason to replace your furnace. Be sure to check all other possibilities before resorting to this one.
