Here are the five most common problems
Improper, haphazard or uncertified A/C wiring is dangerous and a potential fire hazard. Bad wiring often prevents the system from getting power, or can trip the circuit breaker.
4. Low refrigerant
Refrigerant is the chemical that cools the air. Low refrigerant may indicate a leak or problem with the refrigerant system. If your air conditioning system needs to be recharged with refrigerant, typically that means there is a leak. All refrigerant leaks should be located and repaired immediately under the F-Gas regulations.
It is illegal to knowingly discharge refrigerant into the atmosphere!
The outside fan is responsible for transferring the heat from your home to the outside air. If the fan on the outside unit doesn’t run, proper heat transfer is not taking place and the air conditioning compressor may overheat and trip the safety overload. Worse yet, it may cause internal damage to the compressor.
This typically indicates lack of power, contactor problems or even a faulty thermostat; it is not uncommon for someone to have switched off the outdoor isolator to your unit.
A frozen coil often indicates a problem with the airflow, such as restrictions caused by dirty air filters or blocked return air duct work. Frozen indoor coils could also be caused by low refrigerant; a common sign of this may be water dripping from your air conditioning unit, especially if it has no condensate pump fitted.

Server Room Air Conditioning
Server Rooms are a critical part of any business if your air conditioning fails it poses a hazard to your computer systems, and ultimately the functionality of your business, most components are tested to 30°c above this limit there is a strong chance of a failure occurring.
Rapid response and urgent repairs are invaluable to these environments Delta T Services appreciates the urgency of these situations and responds accordingly to fulfil your needs.
Many of the most common causes of failure are due to lack of regular maintenance which can lead to expensive component failure.
These repairs are often preventable with regular maintenance from our skilled engineering staff.
Poorly maintained equipment can use up to 50% more electricity to run than regularly maintained systems. With energy prices’ ever fluctuating it makes sound economic sense to keep your air conditioning and ventilation equipment operating at maximum potential.
With the emergence of the latest inverter technologies in the air conditioning market place it can often make a better financial decision to replace older non-inverter R22 equipment rather than a costly repair, In a majority of cases replacement technology can be used to simply replace the indoor and outdoor units utilising the existing pipe work, drains and cabling.
This method can be very economically viable when compared to such a costly repair as say a compressor change with PCB’S and capacitors.
Our engineers will always offer you the most cost effective solution to your repairs, whatever they may be. It is well worth remembering that new heat pump air conditioning installations into domestic properties qualify for a reduced VAT rate of 5%
This can represent a large saving if the repair costs are quite high for your system.
Is the company you use F-Gas registered? In accordance with the Fluorinated Greenhouse Gases Regulations 2009 No.261. Any company or person working on refrigerated air conditioning should hold an F- Gas certificate Delta T Services certificate number is
