Magic-Pak Coil Cleaning

The condensing coil in your Magic-Pak® units should be cleaned once per year to ensure safe and efficient operation. All Climate Mechanical can tailor the cleaning to meet your needs – from cleaning in place to a complete pull out. We will make appropriate recommendations based on the condition of the units, how well they have been maintained and how long it has been since the last cleaning. 

Thru wall unit coils

On the outside of a standard Magic-Pak unit there are two protective grills. The upper grill is made up of louvers at a downward angle to prevent water from entering the unit as well as to keep the critters out. The lower grill has rectangular slots that protect the condenser coil from hail damage and allow uniform aesthetics. This protective grill also prevents service personal from cleaning the condenser coils from the outside of the building because the grills are only removable when the units are moved forward in the wall sleeve.

Your air conditioning system has two kinds of coils. The evaporator coils are in the air handling facing inside where the filter is located. Air flows across these coils to cool and dehumidify the air inside your home. The condensing coils are in the condensing unit facing the outside of the unit. These coils are filled with refrigerant that alternates between a gas and a liquid form to transfer the heat in your home to the outside air.

 

How A/C coils become dirty

Both the evaporator and condenser coils have a tendency to attract dirt and debris. This is primarily because their surfaces are almost always damp from water condensation. In addition, the cooling fins can serve as perfect places for dirt to collect. Dust is far and away the most common contaminant you’ll find on coils. Even inside your home, there’s always plenty of dust and pollen to coat the evaporator coils. Regularly replacing air filters can help, but over time the A/C coils will inevitably become dirty.

Coil Cleaning

Dramatically reduce the downtime of your HVAC system with routine coil cleaning. How so? An air-conditioning system operating with dirty coils can use up to 37% more energy than a system that operates with clean coils. The cooling capacity of a system without clean coils is also reduced by up to 30%.  It’s important to include coil cleaning as part of routine HVAC maintenance.  If an AC unit requires less energy to operate, it will save money on energy bills, increase the life of your HVAC system and give you a higher return on investment.

 Why Is Coil Cleaning Important?

HVAC coil cleaning is also particularly important to maintain proper air-quality. Mold and bacteria may accumulate inside the system.  The only way to remove it is with a physical cleaning.

The air contains dirt, dust, moisture, pollen, and a myriad of contaminants. These dirty, grimy toxins are absorbed by the coils as air flows through them. As a result, the coils become a breeding ground for bacteria and mold, which can greatly threaten the indoor air quality in addition to making the unit less efficient.

A dirty coil can also reduce air flow causing a change in the coil temperature. This change may cause damage to the compressor.

Reduce Energy Bills

In addition to increasing your AC unit’s lifespan, it can reduce your monthly energy costs. Routine maintenance can even significantly lower your energy bill. In fact, the American Society of Heating, Refrigeration & Air Conditioning Engineers conducted a study that found you can save 10% to 25% of the average operation cost for up to 15 years of service life on your air-conditioning unit or 25% to 55% after 15 years of operation by maintaining coil cleanliness and efficient air cleaners.
