How Dirty Coils Could Lead to the Need For Air Conditioning Repair Service

When your air conditioning turns on its main job is to remove heat from your home and exhaust it outside. If you have a central air conditioning system then you likely have an indoor unit and an outdoor unit that work in unison to accomplish this. Each of these units has in it a series of copper coils that allow for the transfer of heat out of your home. Here at Bob’s Heating and Air Conditioning we offer a full range of air conditioning repair services in Seattle and we wanted to share some of the common issues that can happen if these coils get dirty. Give us a call if your air conditioning system isn’t producing enough cooling or if you’re having any problems with your system.

Seattle Air Conditioning Repairs from Dirty Coils

Your central air conditioning system is often referred to as a “split” system because it has an indoor unit and an outdoor unit. The indoor unit is referred to as the evaporator because it contains the evaporator coils. The outdoor unit is called the condenser because it contains the condensing coils.

In the indoor unit, a large fan pulls in warm air from your home and passes it over the very cold evaporator coils that are filled with a refrigerant. The refrigerant absorbs heat out of the air and is then circulated to the outdoor unit where another fan and the condensing coils exhaust the heat.

You can see now that if either sets of coils get dirty it will restrict the movement of heat between the coils and the air. Here are a few of the most common problems that result from dirty coils.

  • Not enough cooling – Obviously, if the evaporator coils are coated in a layer of dirt and dust they won’t be able to absorb heat out of the air as effectively; and if the condensing coils outside are dirty they won’t be able to effectively exhaust heat from your home.
  • Inefficiency – If it is difficult for your air conditioning system to remove heat from your home then it will have to work harder which reduces the efficiency of your system.
  • Odors – The evaporator coils in your home naturally create condensation and when that mixes with the dust and dirt on them it can allow for the growth of bacteria. This bacteria can produce odors that will seep into your home when your air conditioning operates.
