Air Conditioning Coil Cleaning

Keeping things clean and cool.

How do you clean the air conditioning coil?

Your air conditioning system has two parts – an external cooling unit and an internal evaporator coil. We clean the internal portion. The air conditioning evaporator coils that are right above the furnace in the main warm air plenum. We must clean the air conditioning coils to ensure that the the entire system is clean. If we don’t clean the coils, the dust and debris would blow right back in the ductwork. Additionally, clogged fins can lead to poor air flow (and therefore poor cooling performance), the accumulation of ice, and even damage to the coils.

We do not clean the air conditioning unit outside the home because it is not a part of the duct system. Many manufacturers recommend simply rinsing the external unit with a hose, and using a cover to prevent soiling during the seasons it is not in use.

Where is my AC coil?

Your AC coil is located in the ductrwork above your furnace. Depending on the installer and whether it was put in with a new furnace, or added afterwards, there may be a built in access panel, or we may need to create one.

Can I get my air conditioning coils cleaned without a furnace & duct cleaning?

The short answer: no.

The long answer: We always guarantee our work. Since the entire HVAC system is connected, we have to clean every part of the system including all vents, furnaces, HRV’s, and yes – the air conditioning coils. A complete cleaning prevents dust and debris from returning to the cleaned parts of the system and will prevent frequent visits from us (even though we’d love to see you)!

Alberta Furnace Cleaning Reviews

Andrew led a team total of 3 to clean my furnaces on Sep 4th 2025. The whole cleaning process was very well organized, smoothly completed within 2 hours. They are very professional and use the proper tool to make sure all ducted were properly cleaned.

10 out of 10! I cannot express the detail and outstanding service that the whole team put into this endeavor. From the friendly easy booking over the phone, to my amazing in house cleaning team Ha and Lorenzo. They went above and beyond what was expected and ended up fixing an 8 year old dryer vent issue. It was difficult and those 2 would not give up. I will recommend this company to everyone!

AB Carpet and Furnace cleaned our furnace and vents on Jan 30. Ruzle and Tiq were a great team as they quickly and efficiently cleaned our home. They were respectful and courteous, and I would highly recommend this duo to others. The team arranging the appointment was also wonderful as they made booking the appointment simple, and kept me well informed of the arrival time of the cleaning team. Much appreciated!

I can't say enough about the service I received from Alberta Furnace Cleaning. They came today to clean my furnace vents and my in-house VAC system. My Vents were almost completely clogged with construction materials leftover from when the house was built. We also have two kitties and they contributed to the overall blockage. My furnace is already working at a much more efficient level. Alfredo and Joseph were knowledgeable, polite, and efficient. They left my house and furnace room immaculate before they left. Thank you for the great service!
