Few things are more irritating in the summer months than when your home’s AC unit stops working.
There are several fairly common reasons why it may have stopped, and they’re all fairly simple for a professional to address.
Freon is the refrigerant that air conditioners use to cool the air in your home. If the temperature of the air coming out of your vents or your window unit seems to be fluctuating wildly, this could mean that the Freon canister is leaking.
An HVAC technician will perform a recharge, which means that they’ll refill the canister. Once that’s done, they’ll check the canister for leaks and seal those that are discovered.
Frozen Condenser Coils
If your AC unit isn’t running at all or is only blowing warm air, that can be a result of your outside condenser coils being covered in ice.
Although this can come from low amounts of refrigerant, other likely explanations include a dirty air filter or a blocked air duct.
A technician will figure out the cause, and all of these potential issues are easily fixed.
The AC compressor is what’s used to energize the refrigerant and allow it to do its job. When the compressor’s fan stops working, the AC unit can also stop working.
There’s also a risk of the compressor overheating in a situation like this because it’s receiving too little refrigerant.
Depending on what’s wrong, it can be either fixed or replaced.
If water is coming in through your vents or your window unit, that can simply mean that the outside humidity is very high.
However, it can also mean that your unit’s drip pan or drain lines have been clogged.
In either event, long-term drainage issues can lead to more serious damage of other components.
The technician will check the lines and the pan for algae growth and remove what’s found. They’ll also use anti-algae treatments to keep it from coming back.
If your AC seems to trip the circuit breaker quite often, then there might be an issue with the wiring inside the unit.
This is also true of instances where it just seems to shut off without reason. If you suspect a wiring problem, it should be dealt with as soon as possible since short circuits are a fire hazard.
The contactors are what provide the electrical connection that gets the AC unit up and running. If your unit doesn’t start up right away when you change the thermostat, then it could be time to get the contactors replaced.
An AC technician can provide new ones for you.
Worn-out Evaporator Coils
These are instrumental in providing the necessary air exchanges to keep your home cool. If they stop working and cause hot air to blow inside, then they’ll have to be replaced.
With proper maintenance, however, this can be avoided.
Experts say that a technician should look at these coils every three years.
