Why Is My Furnace Cooling My House in Knoxville, TN?

Obviously, the purpose of your furnace is to keep your home in Knoxville, TN, warm. Feeling it begin to cool your house should therefore provoke immediate action in response. To help you take such action, we’d like to explain why your furnace might have started cooling rather than heating.

Airflow Obstructions

Even if your furnace can produce hot air in abundant quantities, it won’t warm your home unless it can get that air into the right areas. Smooth airflow is absolutely essential for this to happen. Unfortunately, many things threaten to choke off the movement of air through your furnace.

Dirty air filters are easily the greatest of such threats. However, soot buildup in the system’s valves and corroded or malfunctioning parts may also have this effect. Fixing the former problem requires you to clean your filters at least once every three months, and fixing the latter one demands either a round of maintenance or some significant repairs.

Leaky Ductwork

Unless you happen to use a ductless mini-split system in your home, the hot air that your heating system creates will need to pass through a network of ducts before it can reach your home’s interior. If these ducts have holes, warm air will escape, decreasing your furnace’s ability to keep you warm.

Gas Leaks

Do you have a gas furnace? Without natural gas, your furnace won’t be able to generate heat. Therefore, if your furnace has any kind of gas supply issue, be it a gas leak, a blockage or anything else, it’ll expel cool air into your home instead of warm air. Since gas leaks are dangerous, you must leave your home as soon as you notice one and request professional help to handle the problem.

Although natural gas is odorless on its own, it’s common for heating professionals to add the smell of rotten eggs or sulfur to it. This offensive smell will make it easy for you to detect a leak.
