For many of us, air conditioning is one of the only ways we can survive the long, hot summer days and nights. Unfortunately, when we least expect it, our air conditioner can suffer a fault or breakdown. What you may not be aware of is that dirt and dust increase the risk of problems with your air conditioner. Outside air can contain a number of contaminants including dirt and dust, which can find its way into your system despite the air filters. Therefore, it is important to understand the problems and issues that dust and dirt can cause in your air conditioner.
Clogged Air Filters:
A clogged air filter is one of the most common underlying causes for air conditioning repairs. Clogged filters can compromise the efficiency and performance of your system. The filters in your air conditioner are usually close to the returns air vent, which is where the indoor air is mixed with outside air. The filter is designed to protect the components of your system from debris. Unfortunately, if the filter is not regularly changed or cleaned, the airflow is restricted which makes it difficult for the system to pull in air. Some systems also have a safety cut off feature, which will prevent your air conditioner from running if the filters become clogged. This means that not only do you need to clean the filter, but you will also need to refresh the system before you can enjoy the cooled air.
Motor Problems:
Another common issue due to dirt and dust in your air conditioning system is that the fan motor can develop problems. The system requires a fan to draw warm air from the room and push the cooled air back into the room. This is vital for proper distribution of conditioned air and keeping your home at a comfortable temperature. If the fan motor has become clogged with dirt, dust or other debris, it is likely to stop functioning. Once the motor has ceased to work, the efficiency of your system and the cooling of your home will be compromised.
Duct Problems:
Another area of your air conditioning system that can be adversely affected by dirt and dust is your ductwork. Dirt and debris can accumulate inside the ducts and will collect on vents, blocking the airflow. This is particularly the case after construction work. Dust and dirt inside ducts can encourage the growth of mold, which would allow spores to spread throughout your home. Most HVAC experts recommend having ducts cleaned every few years to remove dust accumulation. Signs that your ducts may need cleaning include dust and lint accumulated around vents and increased allergic reactions in family members.
Although it may seem innocuous, dirt and debris can have a massive impact on your air conditioning system. It can increase the risk of problems developing including compromised performance and efficiency. Over time there is a greater risk of a breakdown, and you could end up paying more on your energy bills. Therefore, it is well worth considering how you can minimize the dust and dirt in your home, to keep your HVAC system operating at peak performance.
