Dirty Condenser Coils Cause Problems
Dirty Condenser Coils Increase Power Costs. When the coil becomes fouled with dirt and grime it cannot provide complete or adequate heat transfer, a process that was predicated on a clean coil! The equipment’s compressor senses this, and tries to overcome it by going to a higher system pressure. This consumes greater levels of electricity. For example, a dirty coil could easily consume up to 37% more electricity as compared to a clean coil.
Take a look at a 10 ton air conditioning system operating for an average cooling season of 1,500 hours. When the coils are clean, it will cost approximately $1,650 to operate for the season, given a typical Kw/hr cost and equipment SEER (efficiency). However, when the condenser coil becomes dirty, the six-month cost of operation escalates to $2,268…a 37% increase.
By comparison, if the condenser coil on this unit were kept clean, a savings of $618 could be realized…a savings of about $62 per ton. If you multiply your total building tonnage by $62, you can see what the savings would be. For example, in a typical residential setting, the homeowner could realize a savings in electricity cost of about $248 for the season for a 4 ton system.
As dirt and grime on the condenser coil restrict heat transfer, causing the compressor to work harder, more heat is added to the system and the head pressure could rise by as much as 75%. This would result in a loss of cooling capacity of up to 30%, and our 10 ton system would now only provide 7 tons of cooling…at a higher energy cost and typically on the hottest days of the season.
