Before trying to carry out air conditioner repair in your home or office, there are certain aspects of air conditioning systems you should know about. It is common to see users trying to fix their broken down air conditioners without fully knowing the principle of operation. You will see just how simple AC repair can be by learning HVAC repair. HVAC, or heating, ventilation and air conditioning. should be delegated to those who specialize in it. To handle more difficult and complex repairs contact air conditioning repair Minneapolis.
Simple physics work the normal air conditioner at homes and in offices and consists of two discreet units, the condenser and the evaporator. The freon gas in the condenser is under pressure and is put through a designated Heat Exchangers, heat is removed from the gas and is converted to liquid. It is then passed through an expansion valve into the evaporator; the liquid Freon expands and evaporates to a gas, the latent heat needed for this coming from the environment, which is then cooled (the cooled air then being blown into the room). The gas heated by the higher room air temperature than goes back into the condenser where the heat is removed and the cycle continues.
The evaporator and condenser are sealed units that a trained professional must work on. What you can do is to keep everything clean and all the mesh guards and so on clear of debris. You should not do any HVAC repairs, but you can do some basic servicing to your air conditioning system. Here are some basic air conditioner repair, troubleshooting and service tips.
Check the fuses or circuit breakers of the system fails to run. If they are fine, ensure that the thermostat is not set too high. Call a professional HVAC repair person if lowering the unit 5 degrees doesn't fix the problem.
If it is still not cool, try lowering the thermostat. If it still doesn't work the next thing you need to do is check the condenser air intake. It could be obstructed, particularly during Autumn when the leaves are falling. Ensure the fins are nice and straight. When all else fails, it is best to contact a professional engineer.
If your cooling is uneven or erratic, try cleaning the condenser, and if that fails, call in an engineer. Trees and other plants often wind up blocking units. Make sure that the condenser sits on a concrete pad which is perfectly leveled, as the concrete breaks sometimes and disturbs the level of the condenser and motor. That can affect its operation.
Both the condenser and evaporator are sealed units, which makes it hard to be an amateur HVAC tech. A blocked or dirty evaporator is the most common problem that you can fix yourself. If you have a regular air conditioner service carried out by a professional then you should not experience these problems, except in extreme weather conditions when vegetation and other debris can be blown into the unit.
{You can clean the evaporator unit yourself by first removing the insulation and the evaporator access plate, but it is much safer and more effective in the long run to have a professional contractor that looks after all of this for you on a regular basis.}
