When it’s hot outside, there are few things more devastating than returning home after a long day and finding that it’s just as hot inside your house as it is outside. While it’s very likely your first instinct is to call a service repairman and beg them to come out immediately, there are a few things you should do first when you air conditioning system isn’t working. There are some matters that are simple to fix yourself, but others will require a professional.
– Check The Thermostat
This is a quick and easy fix that has the tendency not to cross your mind. It’s not unusual for a setting to get changed by accident, particularly in a home with children. Don’t ever skip the step of checking the thermostat, regardless of how sure you are that it has not been altered.
– Check The Blowers
The blower is the fan that circulates air throughout your house. To make certain it’s working properly, go to the thermostat and turn the fan switch to “on”. If, after 30 seconds or so, the blower has not come on, you will need to contact a professional. If the blower is working, but there’s little to no air coming from the vents, check your filters, coils, and refrigerant levels.
– Check Your Filters And Coils
One of the most common reasons an air conditioner isn’t able to work properly is because the filters and coils are dirty. Make certain that your filters are not clogged with dust, pet fur, and more. If it is, you may choose to clean it out, but your best option is to replace it. (Keep in mind that filters should be changed monthly for the best results.) Also, ensure your coil is not stopped up with leaves or grass clippings. If it is, turn the unit off and clean it out.
– Check The Fuse Or Breakers And Outside Disconnect Switch
Occasionally fuses and breakers can get kicked to an off position, so never skip this step. In older homes, it is not unusual for circuits to become overloaded and cut power to everything on the circuit breaker. Make certain everything is in the “on” position before you begin to panic. If there’s an issue with the breaker becoming overloaded, unplug nonessential items to decrease the amount of work that is required.
– Check Your Refrigerant Levels
This does require that you contact a professional. If your refrigerant levels are low, the pipe that runs from the outside unit to the inside unit will freeze up. It may be as simple a fix as adding more refrigerant, but it could also indicate a possible leak or blockage. In both instances, the repairman will have to pinpoint the exact location and repair the problem before replenishing the refrigerant. Conclusion If your air conditioner unit is not working properly, do not immediately begin to assume that it is in need of costly repairs. Follow the tips above and you may find that your unit can quickly be repaired without the need of outside assistance.
