Your swamp cooler is one of the hardest working appliances in the summer time. In the peak of the summer heat here in Albuquerque and Rio Rancho they are often turned on early in the morning and left to run well into the evening. Swamp cooler maintenance is important to make sure the unit is running efficiently. Regular maintenance by a HVAC professional ensures that the cooler will have a long life span and swamp cooler repairs are kept to a mimimum.
Swamp Cooler Maintenance
Evaporative coolers at the beginning of the season should be cleaned, oiled and checked for problems. Our water here in Albuquerque and Rio Rancho is very hard and a swamp cooler can accumulate a lot of mineral build up inside over the course of a season. This mineral can clog the blower motor, water pump as well as contribute to the rusting of the cooler casing. It also makes the cooler very inefficient.
The motor and bearings need to be oiled at least once a season to ensure that they operate properly. A blower motor that is not oiled properly will eventually seize and burn out the motor. Blower bearings that aren’t oiled will seize up also and can cause expensive damage to the blower shaft and blower wheel.
How does a swamp cooler work?
A swamp cooler works by drawing the hot outside air through a wet pad. The water in the pad evaporates, cooling the air before it is brought into the house. An evaporative cooler will typically cool a house about 10-15 degrees lower than the outside temprature. High humidity can lower the efficiency of the swamp cooler greatly. To operate efficiently most swamp cooler pads need to be changed every season. They absorb a lot of mineral over the course of the season which clogs the openings making the cooling process less efficient.
Our technicians check all other aspects of the evaporative cooler operation including, water lines, float valves, electrical connections, thermostats, switches and ductwork and many more. We will also safely shut down your furnace or boiler system for the off season.
