Why Is My House Heating Unevenly?

However, a common problem that many homeowners face at one point or another is uneven heating throughout their homes. If this is a problem that you’re currently experiencing, it’s likely caused by one of the many reasons that we’re going to go over below.

Leaky Ductwork

If you’ve checked over your heating system and everything seems to be working properly, it’s time to check out your air ducts. Leaks tend to develop between the different joints over time as the metal naturally expands and contracts. It’s been estimated that most homes lose up to 30% of their heat through ducting leaks. As the warm air moves throughout your ductwork, it will start to seep out the gaps in your ducting. The rooms that do not heat up as well as others are likely after the gaps. To fix this issue, you’ll need to have a professional come in and seal up your ductwork.

Dirty Air Filter

Your furnace has an air filter that is intended to protect the internal components of your system from collecting unwanted dust and debris over time. As your filter naturally works to remove this debris, it will start to become clogged up and need to be replaced. If you don’t replace the filter regularly, your furnace is going to work twice as hard to try to push air through the clogged filter. This will typically result in uneven heating throughout your home, where the most distant rooms don’t get much heat compared to the ones that are closest to your furnace.

System Short-Cycling

Short cycling is the name given to a heating system that constantly turns on and off without finishing a complete heating cycle. This can lead to uneven heating similar to that of having a dirty air filter. The rooms closest to your furnace will be able to receive the most heat, while those furthest away from it are going to be the coldest. Short cycling can be caused by a number of different issues with your heating system. In this scenario, it’s typically best to call an HVAC professional to evaluate the reason for your system’s short cycling.

Failing Heater

Most furnaces are intended to last for around 15 to 20 years. As they reach the end of their life span, they’ll start to output less heat over time. If you’re starting to experience uneven heating throughout your home, it could simply be that your furnace is reaching the end of its life span, and you’ll need to think about replacing it. Whenever your furnace is about 15 years old, it’s time to start looking into upgrading your system.

Incorrect Heater Size

If you’ve recently moved into a new home or you’ve just upgraded your existing heating system, you may be very upset to find out that it’s not producing heat evenly throughout your entire home. This could be due simply to having an undersized furnace. Your heating system needs to be able to output enough heat to match the size of your home. If your heating system is inadequate for what your heating needs are, it’s not going to be able to throw out enough heat to keep your entire home warm. You’re likely to experience the rooms closest to your furnace being warmer than the rooms further away from it. Unfortunately, in this scenario, you’re going to have to replace your existing heating system with a new one that is bigger and more capable of handling the heat output that your home requires.

Home Design

One cause of uneven household heating has nothing to do with the heater itself. Rather, it has to do with the poor design of a home. It’s well-known that multi-level homes are particularly challenging to heat all of the rooms to the same temperature. The higher floors tend to remain at a higher temperature than the ones on the lower level just because of the natural rising of heat. When you throw in other design components like wall-to-wall windows and vaulted ceilings, they create even more of a challenge for your heating system to keep each room in your home at the same temperature.
