Having a home air conditioning system is a necessity for keeping you and your family comfortable during the worst of the summertime heat. Unfortunately, your air conditioner may malfunction from time to time. One of the most frustrating malfunctions is when your air conditioner blows hot air. Below, we’ll address some of the most typical causes so that you can work to repair your system quickly.
One of the most obvious reasons your air conditioner may be blowing hot air is that you set your thermostat to heat instead of cool. If you notice that the air seems to be blowing cold one moment and hot the next, you may have your blower fan on the wrong setting. When your blower fan is set to on, it will run 24/7.
When your air conditioner turns on, it will run and blow cold air. However, when your air conditioner shuts off, it will continue to run and circulate the hot air in your home. This is a simple fix: All you need to do is set your blower fan to auto instead of on.
The air filter inside your AC system is perfect for collecting unwanted debris before it enters the internal components of the indoor air handler unit. However, when your filter gets clogged with debris, it acts more like a wall than a filtration device.
This can cause a restriction in your ducting and make it much harder for your air conditioner to produce an adequate amount of cool air for your home. It will likely feel like the air coming from your vents is very weak and warm. Fortunately, this is another easy fix, as all you need to do is put in a replacement filter to restore the full functionality of your air conditioning system.
For your air conditioner to adequately remove heat from your home, it needs to have a specific amount of refrigerant inside its coils and lines. If there is a leak or a loose fitting allowing your refrigerant to seep out, this can drastically reduce the ability of your refrigerant to remove that heat.
If you suspect that you may have a low refrigerant issue, you’ll need one of our AC repair professionals to further assess the issue. They’ll be able to identify the source of the leak and repair it before recharging your system’s refrigerant level to restore its functionality.
Your air conditioning system has two parts that work to remove heat from your home and transfer it to the air outside: the indoor air handler unit and the outdoor condenser unit. It’s important to note that the outdoor condenser unit typically has its own subpanel box that controls its functioning.
This means that you can shut off the outdoor condenser unit for things like cleaning and maintenance without having to shut off the circuit breaker for the entire system. However, this can be unfortunate when the outdoor subpanel box is shut off and your indoor air handler unit is still running like normal.
You’ll notice warm air in your home but won’t hear the outdoor condenser unit kick on. All you need to do is check the subpanel box and turn it back to its “on” position to restore the functioning of your condenser unit.
One frustrating culprit behind your warm air issue is frozen coils. When there’s a problem with the refrigerant being able to extract heat from the air in your home, it will get super cold and eventually cause ice to form on the surface of the evaporator and condenser coils. In a lot of cases, the reason your refrigerant is unable to extract heat is because the surface of the coil is too dirty.
One of our professionals can thoroughly clean your evaporator and condenser coils if you experience this issue. Our technicians will use a specialized cleaning solution that will be tough on the grime but not damage the integrity of the coils.
