The role of your central air conditioner is to maintain comfortable home temperatures. Homeowners sometimes experience uneven temperatures because of inefficient cooling. What’s more, this situation is expensive, inconvenient and frustrating. Read on to learn why your home in Anderson, SC, could be experiencing inefficient cooling. Faulty or Leaky Ductwork The air conditioning system’s ducts distribute cold air to all the rooms in a house. When they have blockages or damage, they reduce air pressure by allowing the conditioned air to leak. This issue further affects the air conditioner’s efficiency, prevents smooth air circulation and makes some rooms feel hotter. Incorrectly Sized HVAC System The size of an HVAC system should correspond to the size of a home. The system won’t have the capacity to distribute cool air and maintain comfortable temperatures throughout your house if it’s too large or small. If your Anderson, SC, home has a big surface area, a small air conditioner might not have a significant impact on the indoor temperatures. The system can also break down because of straining to cool every room. Inadequate Insulation The quality of insulation in your house also affects cooling efficiency. For example, proper insulation keeps the cool air inside the house and prevents warm air from flowing inside. Poorly installed or damaged insulation makes it difficult for the HVAC system to regulate the indoor temperatures, causing uneven cooling. HVAC professionals usually pay attention to the attic when inspecting the status of the house’s insulation. That’s because hot air often escapes through the attic. Clogged Air Filter A clogged or malfunctioning air filter can negatively affect your HVAC system’s capacity to cool all the rooms in the house. It reduces the flow of air into the system and the quantity of air it cools. That’s why homeowners should change the air filters after one to three months or hire HVAC maintenance service technicians to do so. Faulty Thermostat Another reason you’re experiencing uneven cooling in your home could be that the thermostat isn’t registering accurate temperatures. Adjusting the thermostat’s placement or installing a smart thermostat solves this problem. Leaky or Blocked Air Ducts Your HVAC system may not cool the house evenly if the air ducts are leaking and wasting the cooled air from the system. According to the EPA, leaky air ducts can lead to a loss of approximately 30% of cool air in a residential HVAC system. If you suspect this issue in your HVAC system, ensure that you contact an expert to seal the leaks. On the other hand, locked or closed vents prevent a room from receiving adequate air conditioning. The air ducts transmit cold air into the spaces with open vents, meaning that the rooms with blocked vents are always hot. To avoid this uneven cooling, ensure that you have not placed any carpets, furniture or other items on top of the vents. Old Air Conditioner Uneven cooling is a sign that your air conditioning system is past its lifespan and ready for replacement. Most air conditioners last for about 15 years. Systems older than this have a lower capacity to cool the air evenly and maintain comfortable temperatures, especially in the rooms furthest away. It’s uncomfortable to stay in a house with uneven cooling. Our experienced HVAC service technicians can help you prevent uneven cooling in your Anderson, SC, home by ensuring that your air conditioner works flawlessly throughout the season.
