When the air conditioning stops working on the hottest day of the year it may not be just bad luck. Likely, you did not have an annual check-up to detect problems that could stress the system on the hottest day.
The check-up can begin outside where the external air conditioning components are located. The fins ahould be straight and free of dirt and other debris. The fan is a critical part and it will be taken off and cleaned. Oil should be put in any oil ports that are visible.
The condenser and the condenser coils are located outside, and both of these are sealed which means that only a professional should touch them. The compressor is also located outside. These components are set on a cement slab that should be level, and if it isn’t level then the contractor needs to level it. Trane repair in Bellevue, WA will do this.
The compressor is also located outside with the other outside components. The evaporator is in the furnace plenum and it should be cleaned if it is accessible.
The refrigerant level will be checked and if a leak is suspected, it would be economically wise to find it and fix it. The coolant line insulation will be replaced if it is worn.
The thermostat will be checked to be sure that it is signally the air conditioning system to put out the proper temperature air. The thermostat is a critical part of the system because not only will it control the temperature, but it may be the type that can be set for variable temperatures during a 24 hour cycle.
If the internal components of the air conditioning system are located in the attic, then cleaning the drain port at the beginning of the season is vital. Although the ports are designed to drain outside of the home, if they become clogged the water will begin to drain down the walls resulting in black mold forming.
A S.E.E.R rating should be explained because it will help you understand the age of your air conditioning system. It is a Seasonal Energy Efficiency Rating developed by the U.S. government and equipment manufacturers to indicate an energy usage rating. A S.E.E.R of 6 would indicate it is time to be thinking about a new system.
