With soaring temperature outside and high humidity, the happiest time is when you get back home, turn on the air con, and doze off. But it’s a common complaint of many aircon users that their cooling is not up to the mark when they need it the most. various reason rang from air filters issues to trip circuit breakers, from condenser related problems to problems in Heating, Ventilation, and Air Con (aka HVAC); the most common reason for less cooling is gas related issues in the compressor. In this Articles, we will demystify complex term and help you get an insights into the roles gas play in cooling your room and how by followings a few simple steps you can ensure complete peace of mind in so far as getting the desired cooling is concerned.

The Role of Gas in Air Conditioning



AC gas, also known as Refrigerant, is a liquid used in air conditioning systems. It absorbs heat and humidity from the room and throws it out in atmosphere. A refrigerant change its state from liquid to gas and gas to liquid depending on its requirement. Till the 1990, harmful CFC (aka Freon) was used in air con. From 1990 onward, it was replaced by HCFC or Hydro chlorofluorocarbon, although the presence of chlorine in HCFC based cooling systems made it hardly any better than CFC based systems. Recently, air con manufacturers have invented another refrigerant called Hydro Fluoro Carbon or HFC. This new set of refrigerants are proven to not deplete ozone layer and thus somewhat reduce the harmful effect of global warming due to use of air con. But the best innovation in this fields has been Hydrocarbon or HC based refrigerant. Being Halogen free, this refrigerant is way better than the existing refrigerant available in the market.  

Reason 1 – To save yourself from spiraling cost of refrigerant


Majority of air con use HCFC based refrigerant. Because of its ozone layer depleting characteristic, many developed nations have decided to phase out its use by 2020. Hence, if you still possess an air con system which uses HCFC, getting the gas recharged in case of a leak can cost a fortune as most HVAC contractors only get a limited supply of HCFC refrigerants. Air con gas may leak for various reasons like acid rain, toxic fumes, proximity to coastal region, and poor fitting. In order to ensure that your AC stays on prime of its health, call an HVAC contractor to tune-up your system to diagnose and aircon repair any potential leaks. During tune-up, ask your HVAC contractor to pay special attentions to Dryer Joints, Accumulator Joints, Stainer Joint, Stopper Filter, Capillary Valve, and Condenser Coil.

Reason 2 – To save up on electricity bills


Due to refrigerant leak or low refrigerant, an air con unit doesn’t cool properly. An incorrectly wired thermostat accelerate the problem by triggering both heating and cooling system at the same time. Insufficient refrigerant struggle to remove heat from your room as the system has to work vigorously to gratify the need of the thermostat. Prolonged use of aircon without aircon maintenance reduces the life cycle of the coils as well as the line sets which further aggravates the pressure on the refrigerant. Hence, whenever you find that with the same kind of air con usage, your electricity bill is most, it’s time to conduct a check. In order to saved yourself from escalating electricity cost, it’s prudent to call an HVAC professional to refill the refrigerant or aircon repair any leak. You must be a bit careful at the time of choosing any air con professional. Just make sure the person you are calling has a good experiences in dealing with air cons.

Reason 3 – To save your air conditioning unit from water leakage


In case of low gas in air con unit, vaporization often remains incomplete. Due to incomplete vaporization, aircon water leakage takes place. Aircon Water leakage may also happen due to congested drain pipe, old drain pan, dysfunctional condensate pump, and unclean air filters. But most often than not, the main culprit behind all water leakage problems is refrigerant, since low level of refrigerant reduced the Air pressure in the system leading the coil to melt.

Reason 4 – To get the best out of the aircon servicing your technician offers


An air con is more of a utility than a luxury. And in order to maintain your air con for a longer period of time, you must take proper care of it. Ideally after every three months, you could schedule a service of your aircon service in singapore. And if after inspection, the technician find that the gas level in your aircon has dropped by more than 10%; then it’s high time that you aircon gas top-up .

Reason 5 – To increase the running time 


Be it a 24 x 7 office or a house with ailing people, there are places which can never think about turning off its air con. More usage means most load on the compressor; enhanced load on the compressor means more gas consumption. Also, in automatic air con, the compressor turns off when the room temperature attains the set temperature. But, sometime, the compressor turns off even when the temperature is nowhere near the set temperature. This is a common problems associated with low gas. Hence, it’s good to top up gas at frequent interval to achieved desired cooling.
