Why is One Room Cool While Others are Hot?

Inconsistent cooling in the home is one of the most common reasons homeowners contact us for service. Hot and cold zones around the home are not only an annoyance, they’re a sign that the home’s air delivery system is not operating correctly. Many homeowners will simply close or open vents, or adjust the thermostat well above or below where it should be to maintain a comfortable setting. This wastes energy and can shorten the life of your air conditioner.

Several factors can contribute to uneven cooling, but, fortunately, they can all be fixed. Here are a few things that you can do to address uneven cooling in your home

Have Your Home’s Ductwork Inspected

If airflow to certain parts of the home is imbalanced, you’ll experience uneven cooling in those areas. An airflow imbalance also causes your system to work overtime in order to compensate, which in turn will shorten your system’s life and decrease its efficiency.

In order to create a balanced airflow ABC Southwest will need to inspect and assess the adequacy of your home’s ductwork. If the ducts are not properly sized, it’s important to replace them with correctly sized ones.

Identifying leaks and blockages is also important, as leaks are a major contributor to inefficiency and uneven temperatures. If blockages are identified, they will be removed to restore airflow. Once the underlying causes of the imbalance have been identified, the appropriate repairs or replacement will be made to get your system functioning normally again.

Variable Speed Motors

Variable speed motors provide more even heating and cooling, and allow for more precise control of airflow throughout the home. By moving the air more slowly through the system, variable speed motors can help make a home’s air filtration and moisture control systems more effective. They adjust the system’s output based on the home’s cooling needs. They can also be helpful in situations where uneven cooling is actually desired. If there are rooms in your home that are rarely used, you can save money by keeping them at a slightly higher or lower temperature than the other rooms in your home. This involves “zoning,” which means customizing temperature settings for different areas of the home. In general, variable speed motors are the only systems that allow for zoning within the home.

Ensure Your Air Conditioning System Is Sized Correctly

Just as you’re experiencing discomfort due to uneven temperatures, your system is constantly trying to compensate, which means high utility bills and the potential for costly repairs.

Sometimes, an improperly sized HVAC system may result in uneven cooling. This could be the result of either an incorrect load calculation at the time of the system’s installation or a home’s heating and cooling needs changing over time. For example, it is common that an extra room is added or an area like an attic is converted into living space. If your HVAC system is too small to properly heat or cool your home, uneven temperatures and system failures could result. To determine whether your HVAC system is properly sized, contact ABC Southwest Plumbing & Air Conditioning for an up-to-date load calculation.
