It's important to remember that, while refrigerant shouldn't run out, it can. The only reason your air conditioner's refrigerant levels might change is if there is a leak in the copper coils or at connection points. This is a serious problem that will keep the AC system from working properly.
No. Freon is a VERY stable molecule and won't break down over time. The only way it can escape from a cooling system is via a leak of some sort.
Most systems need Freon replacement anywhere from once every two to five years from a professional HVAC Contractor. The most significant exception to this rule is when there is a leak in the air conditioning system, which decreases the amount of refrigerant in an AC unit over time.
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.
As mentioned earlier, Freon costs about $125 – $150 per pound. Most homeowners will pay in the range of $200 to $400 for a refill, depending on the type and size of their HVAC unit.
All AC units are designed to keep the refrigerant (Freon) for the life period of the unit which is 15 to 20 years.
First, check your filters and coils for dirt and debris that may be impeding airflow. Once you've cleaned the filters and coils, run the air conditioner with just the fan so that the ice accumulation can melt off. If the AC still doesn't blow cold air, it could be that refrigerant levels are too low.
Under EPA regulations, only a certified professional can recharge your home's HVAC system. You should never try to recharge the A/C yourself, even if you have a home air conditioner recharging kit. The refrigerant used can be harmful to you and the environment if it's not handled properly.
It's important to note that low refrigerant levels don't always mean a leak. We often receive calls at Watkins Heating & Cooling from customers with low Freon who had their HVAC system installed by other companies.
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.
If you suspect a freon leak, head outside to the exterior AC unit. The evaporator coil is in the back of your AC unit and leads directly into your home. If this coil is physically cold and there are visible signs of frost, your refrigerant levels may be leaking. You should then turn your AC unit off completely.
Unless there is an actual hole or crack within the compressor holding the freon, the freon level remains the same. Therefore, an AC will never require a recharge of freon unless without the presence of a leak. The other question that homeowners have is whether they can run an AC when it is low on refrigerant?
Low AC refrigerant can put a strain on the AC compressor, causing it to work under duress. This stress can result in strange noises like grinding or hissing sounds coming from the unit.
There are a number of reasons why your air conditioner might be running but not cooling. It could be an issue with the thermostat, the compressor, or the evaporator coils. Or, it could simply be clogged with dust and debris, which is preventing it from working properly.
Yes, you should turn off your AC if it's not cooling.
Check these issues when the unit won't kick on: Check the thermostat and adjust the settings if it isn't set to Cool and an appropriate temperature setting to call for cooling. Examine the house circuit breakers for the AC unit and reset any tripped breakers. Check the air filter and replace the filter if it's dirty.
Air conditioner Freon refills cost between $100 and $600 for most residential properties, with an average cost of $300. Freon was a brand name that has become a generic term for AC coolant or refrigerant. Most current residential AC systems use R410A refrigerant, while older units may use R22 coolant.
Strain on the Compressor
When the Freon level is low, the ac compressor works harder to maintain the cooling process. This increased workload can lead to compressor overheating and potential damage, resulting in expensive repairs or even the need to replace the compressor entirely.
Most ACs nowadays come shipped from the manufacturer with the exact amount of refrigerant that it will need for the duration of its life. So, unlike a car, your AC won't ever need to “fill up” on refrigerant unless something goes wrong with the system.
The Environmental Protection Agency (EPA) began the phase out of Freon in 1992 when it ordered the ban that took effect in 2020. Because of the long phase-in starting in 2010, new air conditioning, heat pumps, and refrigeration systems stopped using Freon, which is also known as HCFC-22 and R-22.
