What’s Causing the Uneven Heating in Your Home?


You’ve noticed something wrong in your house now that the weather’s colder and you’ve turned your central heating system on. Not all the rooms are getting as warm as they should, and you’ve got family members complaining. A central heater is supposed to provide heat to all of the living spaces, but your heater isn’t living up to that promise.

What’s happening? There are several possibilities, and the remedy may require that you call our technicians for heating repair in Yakima, WA. We deliver timely service and back up our work with a 100% satisfaction guarantee.

The Common Causes of Uneven Heating

Let’s take a look at the most common reasons that your heating system isn’t evenly warming your house.

The heating system is undersized

If this is a new heating system, this is one of the major possibilities to consider. Installing a central heater requires technicians to carefully size it so it puts out enough heat for the house. Failure to do this right, or to do it at all, risks an undersized heater that won’t be able to warm the entire house. This often happens when amateurs do the job. The only way to correct this is to have the heater replaced—and have licensed technicians like ours do the job so you get the right sized system.

The air filter is clogged

The air filter protects the interior of your heating system from dust and dirt. After one to three months, the filter will become so dirty that it will block airflow, leading to a lower volume of heated air getting to the house. You can correct this on your own: just put in a clean filter. We recommend keeping up with regular checks on the filter and changing it every one to three months.

The heating system is short-cycling

Short-cycling is when a heater cuts off its standard heating cycle early, then restarts a short time later and repeats the process. Short-cycling doesn’t give a heating system enough time to distribute heat throughout a house, causing uneven heating. Short-cycling also wastes immense amounts of power and causes components to rapidly wear down, so you’ll want HVAC experts to investigate and solve the problem right away.

The air ducts have leaks

Your heating system may be putting out enough heat, but on the way to several of the rooms that heat might be escaping through holes and gaps in the ducts. Duct leaks are a common HVAC problem, and solving them requires having professionals test the ventilation system, locate the leaks, and use special equipment to seal them. Duct leaks cause numerous other problems, including energy waste and poor IAQ, so don’t delay having them sealed.

The heater is failing

If your heating system is near or past its manufacturer’s life expectancy estimate, then this uneven heating may be a warning sign that the heater is losing its capacity because of age. Although repairs may be able to turn this around, it will only be a temporary patch-up, and the heater will soon start to fail again while racking up higher bills. Our technicians can tell you when it’s best to move on and have a new heater installed.
