No air conditioning unit would function without a refrigerant. It’s a compound that transforms from liquid to gas and back, absorbing heat from the indoor air and releasing it outside in the process. If you have issues with this chemical, you have to get help from a business that offers an air conditioning service Bromley.

But how do you know if it’s time for a refrigerant recharge? Here are seven signs you need to be aware of.

Your AC can’t keep your space as cool as before. If your AC loses its cooling power, you’d definitely have to call for an expert in heating and air Conditioning Sevenoaks. One of the most common culprits behind this is low refrigerant levels. As mentioned, the refrigerant is responsible for absorbing heat from your home. If your place is not cool enough, it means that there’s less refrigerant inside your unit.

Your AC blows warm air. If you go near your unit and you feel hot (or lukewarm) air coming out of it, you’d need to have your refrigerant refilled. Proper inspection is needed, however, because other reasons could also cause this. These include an unclean outside unit, a compressor issue, or an erroneous thermostat fan setting.

Your AC has ice or frost formation. Do you see ice on your refrigerant line? If you ask any air conditioning service Bromley professional, it’s highly likely to be caused by low levels of refrigerant. Low refrigerant means there will be lower pressure inside your AC. Consequently, low pressure means lower temperatures, causing some parts of your unit to freeze.

Your AC clutch fails to engage. When you set your AC to maximum coldness, your AC clutch will produce a clicking sound once it engages upon getting a signal from the pressure switch. If your unit is low on refrigerant, the pressure switch won’t activate. This, your AC clutch will not engage and you won’t hear that familiar sound.

Your AC makes a hissing or a bubbling noise. Speaking of sounds, you have to be alert once you hear a hissing or a bubbling noise. This noise is most probably coming from refrigerant leaking outside your unit. If it’s hissing, the refrigerant leaks in its gaseous state. On the other hand, if it’s bubbling, the refrigerant escapes in liquid form.

You notice visible signs of refrigerant leakage. The abovementioned noises aren’t the only indicator of refrigerant leaks. You also need to get help from a heating and air conditioning Sevenoaks professional once you see a greasy film in any of your AC’s components. Another tell-tale sign is having a pool of refrigerant under your unit. If this won’t be addressed, your AC’s performance will continue to deteriorate, leading to costly repair or, worse, replacement.

Your energy bills keep getting higher. Leaking refrigerant causes your AC to perform inefficiently. Without enough of this compound, your unit won’t be able to cool your space as it should be. This results in a higher energy bill. If your bill keeps getting higher, you have to have your AC inspected. This can also be caused by other issues, like a dirty air filter or an aging system.
