When Is Uneven Heating Caused By A Broken Heater?

Is your home heating unevenly? It might be a quick fix, or it might be a sign you need heater repair.

Bad Airflow

One of the common causes of uneven heating in a home is blocked or restricted airflow within the HVAC system. When airflow is impeded, it disrupts the proper distribution of warm air throughout the space. Some areas may receive less warm air, resulting in noticeable temperature differences. This issue can arise due to several factors, such as dirty or clogged air filters, closed or obstructed vents, or problems with the ductwork. 

In some cases, you can restore your airflow by simply changing or cleaning your airflow or moving furniture and other obstructions away from your vents. If you can't find an easy fix a heater repair contractor will need to inspect your heating system for potential problems in your ductwork or with your heater's blower fan. There can also be other problems that are reducing your heating power making your heater unable to heat your entire home evenly.

Thermostat Issues

Uneven heating can also be caused by thermostat issues such as malfunctions or poor calibration. When the thermostat isn't functioning properly and doesn't accurately read the temperature in your home, it may lead to the system turning off prematurely or failing to activate when needed.

Older thermostats can also fail over time. Electronic components might wear out or get damaged by vibrations in your home. Moisture also could have gotten into your thermostat. Your heater repair contractor can change out the thermostat and check for wiring problems or other issues that might have caused it to go bad.

Imbalanced Dampers

Many newer homes have dampers that help direct the airflow around your home. The dampers can allow you to have different temperatures in different rooms or simply make it easier for your heater to evenly heat even the farthest areas of your home. Some dampers are manual, while others are electronic and work automatically.

Dampers can fail when parts wear out over time, when they get clogged with dust or other debris, or if they get damaged by rodents that got into your ductwork. Damper repairs are especially difficult because the dampers are deep inside your heating system and hard to access. A heating repair contractor can use special tools to find out which damper is causing the problem to avoid unnecessarily tearing out other areas of your home during repairs.
