Delta T Services have been carrying out air conditioning repairs in London and Essex for over a decade giving our customers a prompt and efficient service every time.
It is our experience that the vast majority of air conditioning repairs occur as a result of systems which have not been subject to any regular maintenance or servicing. Typically when being used in a residential environment we would normally recommend two service visits per year, but for more critical use, i.e. server rooms, trading floors, retail shops and restaurants, we would normally advise that your air conditioning be serviced four times a year.
If your air conditioner is low on refrigerant, either it was undercharged at installation, or it has a leak. If it leaks, simply adding refrigerant is not a solution and no longer legal under the F-Gas regulations. A trained technician should fix any leak, test the repair, and then charge the system with the correct amount of refrigerant. Remember that the performance and efficiency of your air conditioner is greatest when the refrigerant charge exactly matches the manufacturer's specification, and is neither undercharged nor overcharged. Refrigerant leaks can also be harmful to the environment and damage the ozone layer.
Here are a few of the many causes of an air conditioning system failure.
If you allow filters and air conditioning coils to become dirty, the air conditioner will have to run for longer periods to give the required cooling or heating, this will cost you money in excessive electrical usage, this can also lead to bacterial build up on coils and drain pans and algae blockages in pumps and drain lines.
When the coils and or filters become dirty the internal pressures within the system increase dramatically, in the case of R410A refrigerant the operating pressures can reach in excess of 600 PSI that is equivalent to more than twenty times a car tyre pressure.
This higher pressure means the system components are under a far greater strain than normal; this in itself will give rise to premature failure of compressors, fans, valves and possibly pipe fractures or loss of refrigerant.
Electric Control Failure
The compressor and fan controls can wear out, especially when the air conditioner turns on and off frequently, as is common when a system is oversized short of refrigerant or overcharged.
Because corrosion of wire and terminals is also a problem in many systems, electrical connections and contacts should be checked during maintenance or repair visits for tightness to prevent arcing.
Room air conditioners feature a thermostat sensor, located behind the control panel, which measures the temperature of air coming into the evaporative coil. If the sensor is knocked out of position, the air conditioner could cycle constantly or behave erratically. The sensor should be near the coil but not touching it, this can happen if the evaporator coil freezes up and forms a block of ice forcing the sensor out of position.
When it's humid and the air conditioning system is on cooling mode large amounts of condensate will be produced, if the system has not been maintained the drain lines can become blocked with algae, pumps can become clogged or float switches stuck, this often causes a condensate pump failure and is one of the most common faults on an air conditioning system.
Regular flushing with a bactericide during maintenance prevents this happening in nearly all cases.
If your air conditioner is low on refrigerant, either it was undercharged at installation, or it has a leak. If it leaks, simply adding refrigerant is not a solution. F-Gas regulations state that it is illegal to top up a system that you know has a refrigerant leak, to this end you should fix any leak, pressure test the system, and then charge the system with the correct amount of refrigerant. Remember that the performance and efficiency of your air conditioner is greatest when the refrigerant charge exactly matches the manufacturer's specification, and is neither undercharged nor overcharged. Refrigerant leaks can also be harmful to the environment and are a cause of ozone depletion.
We at Delta T Services are aware just how important air conditioning repairs can be to your business or home. The air conditioners that we supply are as reliable as they are efficient.
Usually regular servicing is enough to keep your air conditioning system running smoothly. If however, your air conditioning suffers a break-down, fault or malfunction, your climate can change rapidly. If your server room air conditioning fails, the life of your equipment can be reduced or its function impaired. Either way, you'll need a swift and efficient repair service to get things back to normal as soon as possible.
So do not delay contact Delta T Services for all your air conditioning repairs in London and Essex.
