If you’ve ever walked from one room in your house into another and felt a major temperature difference, you’re not alone. Many homeowners in the greater Greenville, SC area struggle with rooms hotter than others — especially during the spring and summer months when air conditioning systems are working their hardest.
Uneven temperatures throughout your home aren’t just uncomfortable, they can also be a sign that something isn’t working properly within your HVAC system. If left unaddressed, these issues can lead to higher energy bills and unnecessary strain on your equipment. Below are the most common reasons you may have rooms hotter than others in your Greenville home, and what you can do about it.
Blocked Air Filters
One of the simplest and most overlooked causes of rooms hotter than others is a clogged air filter. Your HVAC air filter is designed to trap dust, dirt, and debris before they enter your system. Over time, the filter becomes full, which restricts airflow. When airflow is reduced, certain rooms may not receive enough cooled air, resulting in noticeable temperature differences. If you haven’t checked your air filter recently, start there. Replacing your filter every 1–3 months can dramatically improve airflow and help eliminate uneven cooling issues.
Clogged or Leaky Air Ducts
Your ductwork is responsible for delivering conditioned air to every room in your home. If there are leaks, gaps, or blockages in the ducts, cooled air may never reach certain areas, leaving some rooms hotter than others. Dust can build up overtime in your ductwork which gradually forms blockages. In addition to poor airflow caused by blocked air ducts, your ductwork can also leak which diverts airflow in your home. Either problem can be detected by the professionals here at Eastergard HVAC with an inspection of your ductwork.
Signs of duct problems include:
-
Weak airflow from vents
-
Whistling sounds in walls or ceilings
-
Higher-than-normal energy bills
-
Certain rooms consistently warmer than others
A professional duct inspection can identify leaks or restrictions and restore proper airflow throughout your home.
Blocked or Closed Air Vents
Sometimes the solution is simpler than you think. Furniture, rugs, curtains, or décor items placed in front of vents can restrict airflow and cause rooms hotter than others in your house. Additionally, closed or partially closed dampers inside your duct system can reduce airflow to specific areas. The air vents and registers throughout your Greenville, SC home output the cooled air circulated by the AC unit and if something is too close to them, it can block the opening which results in poor airflow. In addition to furniture blocking your vents and registers, your dampers can also be obstructed and if closed, they can also decrease the airflow in your home resulting in decreased comfort and an increase in energy usage from your HVAC system.
Incompatible HVAC System & Ductwork
If you consistently experience rooms hotter than others, even after addressing filters, vents, and ducts, your HVAC system itself may be the issue. An improperly sized HVAC system or incompatible ductwork can impact the airflow in your Greenville, SC home. If your ductwork is too large, your AC unit can struggle to maintain the necessary pressure and if too small, airflow will be restricted.
