Located above
your furnace is the evaporative coil, also known as the “air conditioning
coil. The evaporative coil is made up of tiny fins that absorb heat and
cool the air. These fins are so close that the coils can essentially
become a filter, screening out and collecting dust from the air. Debris
acts as an insulator preventing effective heat transfer, dramatically
reducing the efficiency of the coil. The evaporative coil must be kept
clean so that air can pass freely through the coil fins throughout the
heating and cooling seasons. 
Located outside
of your home is the condensing coil. The condensing coil is also made
up of tiny fins, which expel the heat that the evaporative coil has absorbed.
The condensing coil must also be kept clean. Maintenance:
Maintenance is essential. The lack of routine maintenance can gradually decrease the 15 SEER unit that you bought a few years ago to a 13 SEER unit today. The good news is that it is easy to restore the air conditioner coils and recover efficiency. Using specialized tools and cleaning agents, Ductworks, Inc. can remove impacted debris and restore your airflow to top working order
- Have the air ducts cleaned prior to the installation of air conditioning.
- Remember to buy good filters and change regularly during the cooling season.
- Clean the condenser coils every year.
- Maintain scheduled maintenance with your air conditioning contractor.
Installing A/C?
If you are installing air conditioning, it is crucial step that air ducts be cleaned prior to the installation. When the evaporative coil is installed it should be noted that the process of installation will disrupt and loosen dust settled in the ducts. Since there can be an appreciable amount of surface area inside the ductwork, considerable amounts of dust is accumulated. Cleaning the air ducts prior to installation will prevent the dust from being drawn into the new coils.
