Too little refrigerant also risks freezing the evaporator coil inside your home. The first problem with a frozen coil is the airflow restriction it causes, preventing air from circulating back out. The second problem is the water it creates once the ice melts, risking further damage around your AC.
Running your system will a known low refrigerant situation means your system will not be working efficiently either from a heating/cooling perspective and will be less efficient electrically. Bottomline, it is an unwise decision to continue to run your system when you know it has a low refrigerant level.
An air conditioner without enough refrigerant will continue to run as it tries to cool the home — running much longer than it would normally.
If the Freon levels are too low, the clutch will fail to engage which means there's not enough refrigerant for the compressor to pressurize. In other words, your air conditioning system has nothing to work with!
Freon Leak: What Should I Do If My AC Refrigerant Is Leaking? The short answer is: You should turn off your AC unit and unplug it from the power source. If the leak is small, you can try to repair it yourself using a sealant or tape.
When your AC unit is low on refrigerant, it has to work harder to cool your home, which can lead to higher electricity bills and breakdowns. Once diagnosed, call a professional HCAC company to fix the problem. Now let's discuss how to tell if your air conditioner needs freon.
Can you stay in a house with a Freon leak? While a small leak in your AC unit may not pose an immediate danger, it's essential to address the issue promptly. Leaking refrigerant can lead to inefficient cooling and higher utility bills, and prolonged exposure might cause health issues.
Low refrigerant can lead to compressor damage and inefficiencies of the air conditioning unit. When there isn't enough refrigerant in the unit, the evaporator coil becomes much colder than it should be, causing the moisture on its line to freeze up.
While it might be tempting to ignore a slight drop in cooling performance, the risks of running your AC system on low refrigerant are simply not worth it. From compressor damage to frozen evaporator coils, the potential for costly repairs grows with every mile you drive without addressing the issue.
LOW REFRIGERANT
Improper refrigerant fluid levels can also cause an HVAC unit to freeze up. When the refrigerant is low, the coils will be too cold, causing them to freeze. You can hire air conditioning service and repair to check your refrigerant levels and replace them, if necessary.
While the refrigerant in your vehicle can escape even without a leak, it's often not enough to cause significant issues unless you've failed to top up the refrigerant for years. When the lack of refrigerant becomes significant though, it can cause a number of problems, including an overheating driver in the summer sun.
Arguably the largest issue with low refrigerant levels is damage to the compressor. Low refrigerant levels decrease pressure which causes serious damage to your compressor, eventually causing it to collapse. Replacing your compressor is extremely expensive and should be avoided if possible.
If you set the thermostat too low, it strains the AC. This leads to air conditioning malfunctions and costly repairs.
The only way an air conditioner runs out of freon is if there is a leak in the pipes that carry refrigerant from one part of the unit to the other. Freon is not used up: it simply changes state from gas to liquid. Freon should never escape the pipes.
Too little refrigerant also risks freezing the evaporator coil inside your home. The first problem with a frozen coil is the airflow restriction it causes, preventing air from circulating back out. The second problem is the water it creates once the ice melts, risking further damage around your AC.
An AC leak will lead to warmer air from your vents over time. In most cases this can be fixed with a proven stop leak additive to seal up any leaks. When it's time for an AC recharge, turn to AutoZone.
Compressor will not run without freon. The low pressure switch shuts it off.
The clutch relies on the pressure of the system to engage on most vehicles. If the refrigerant is too low or too high, the vehicle may not allow the compressor clutch to engage. Whatever refrigerant is in the system won't be circulated, and your car won't cool.
It's generally a good idea to turn off a broken A/C. Continuing to run the system when it's not functioning properly can cause further damage, increase energy bills, and even lead to more costly repairs.
If you simply need a top off of refrigerant, you can expect to pay anywhere from $160-$375. If you need a repair for the leak itself, you can anticipate a higher bill. For refrigerant leak detection and air conditioning repair you may pay anywhere from $550 to $1,600.
3. System Damage. Operating an air conditioning system with a refrigerant leak could cause considerable damage to the system. The compressor, a key component of your AC, relies on refrigerant to function and cool.
So, what happens if you do just add refrigerant to a leaking AC system, or don't get it fixed once the leak is reported? The EPA will fine you. There is no way to sugarcoat this. The fine can be as high as $37,500 per day.
The answer is that Freon should last forever unless you have a leaking system. Contrary to popular belief, units shouldn't need to be recharged every year. Many customers call our office because their AC system isn't working as it should.
