Air Conditioner Repair: Everything You Need to Know


Before attempting to carry out air conditioner repair in your house or office, there are particular aspects of air conditioning systems you should know about. When their ac system breaks down or develops a mistake, many men and women try to fix it themselves without fully understanding the concepts involved. However, AC Repair Kennesaw is possible that you carry out a basic air conditioner service as soon as you understand the principles, although HVAC fix (heating, ventilation and air conditioning) is best left to the professionals.


The normal house or office air purifier functions by simple physics, and consists of two different components: the condenser and the evaporator. In the condenser, Freon gas is put under strain subsequently passed through a heat exchanger, removing heat from the gas and converting it to a liquid. It is then passed through an expansion valve into the evaporator; the liquid Freon expands and expands to a gas, the atmosphere heat needed for this coming from the environment, which is subsequently chilled (the chilled air then being blown into the room). The gas heated by the greater room air temperature than goes back into the condenser in which the heat is removed and the cycle continues.

Both the evaporator and condenser are sealed components and you cannot carry out any air conditioner repairs to yourself: you’ll need to telephone a trained practitioner. Everything you could do is to keep everything clean and all of the mesh guards and so on clear of debris. You can carry out simple air conditioner service yourself, but not HVAC restoration. Below are some fundamental air conditioner repair, cleaning and support tips.

1. System fails to run.

Check the fuses or circuit breakers. If they are fine then check that the thermostat isn’t set too large. Try lowering it by 5 degrees, and if this fails you need an expert HVAC repair engineer.

2. No Cooling.

Again, check the thermostat and try trimming it. If this doesn’t work check the condenser air consumption. It may be obstructed, particularly in autumn if there lots of leaves flying about. Check the fins of the fan are straight, and should not straighten them. If nothing works, then phone a professional engineer.

3. Erratic Cooling

With this and all other flaws, all you can do is to clean the condenser it as much as possible, and if this fails call an engineer. It is not uncommon for units to be blocked by plant of one kind or another. The condenser will likely be sitting on a concrete pad: make sure that is flat, because concrete can sometimes break down and place the condenser and the motor from the level. That can affect its performance.

The condenser and evaporator are sealed units, which it is why it’s really difficult for amateurs to carry out their particular air conditioner repair. A blocked or dirty evaporator is the most common problem that you can fix yourself. In case you have a regular air conditioner service carried out by a specialist then you shouldn’t experience these issues, except in extreme weather conditions if vegetation and other debris can be blown into the unit.

You are able to wash the evaporator unit yourself by removing the insulation and the evaporator access plate, however it is much safer and more successful in the long run to have an expert contract that looks after all of this for you on a regular basis.

Frankly, in spite of those that try to do themselves, HVAC fix is a job for professionals should you need it done correctly. Should you attempt it yourself you don’t only have the problem of getting to the units, then the greater difficulty of having a secure fix, but you have to put it all back together in a safe fashion.
