How are you everyone?.
If you followed the current affiars news recently there are talks about Air Quality in reference to young life which was lost in Eastern Cape province because the Air Quality was compromised. May their souls rest in peace.
Did you know there are SANS standards of air quality for any space?. Might be commecial Offices, Hospitals, Businesses premises, Domestic rooms etc, there should be enough air change mechanism (ventilation) to sustain life of humans, animals or plants in it.
Air changes is the amount of fresh air supplied into a space against amount air removed. If the amount of fresh air (oxygen )is reduced with less amount of air removed in a space were human and animals are occupied my cause the increase of carbon dioxide wich can cause health complications, to the worst extant death.

"INVETER" Im sure it is a term which is now common to Air Conditioning and also in Refrigeration and you wonder what it is it?
In simple terms the term inveter in electrical means a component that change Direct current (DC) to Alternative current (AC).Thus it is installed with a regulator in Air cons and refrigerators that changes AC to DC (Regulator) then the DC is inverted to low voltage AC and is passed through a Variable Speed Drive (VSD) component so that the low voltage and the Frequency is also varied by VSD depending with the demand of the temperature.
For an example on a Air conditioner which is to cool down to 17°C a room which is 25°C.The vsd will increase hertz hz (frequency) higher to make the compressor run faster to reduce quickly the heat load, once the temperature is close to 17°c the vsd reduce the hz to reduce speed of the compressor to lowest to save energy until it cuts out and starts again under low frequency speed just to maintain the temperature .Keeping the energy demand at low level and saving money.
Therefore it is advisable to invest in " INVETER" Technology for it is green at environment , saves money , low noise decibels and durable .
COLDER HVAC has inveter Air cons and Refrigerators in stock and have qualified technicians to install, service and repairing.

Is it normal to refill gas to my cooling system frequantly in a year?
Most common asked question we get in the industry.Infact a refrigeration circuit is made of metal tubes mostly copper,steel and alminium which sealed to contain gas( freon or refrigerant) by brazing and flaring joints .Usualy most of those sealing points are done and tested by the manufactures and installers and service technicial will do the the flare joints , when done correctly it will contain pressure for ever.
So it should not leak gas so frequantly as asked above.
As COLDER our technician are qualified , trained and do have modern equipments to check leaks , and will fix the leaks.
COLDER we do the best practice.
