Before trying to carry out air conditioner repair in your home or office, there are certain facets of air con systems you have to know about. When their air con system stops working or develops a mistake, many people try to fix it themselves without fully understanding the concepts involved. However, it is possible for you yourself to carry out a simple air conditioner service once you realize the principles, although HVAC repair (heating, ventilation and air conditioning) is best left to the professionals.
The standard home or office air conditioner functions simple physics, and includes two discrete units: the condenser and the evaporator. In the condenser, Freon gas is put under some pressure then passed by way of a heat exchanger, removing heat from the gas and converting it to a liquid. It is then passed through an expansion valve to the evaporator; the liquid Freon expands and evaporates to a fuel, the latent heat necessary for this from the environment, that is then cooled (the cooled air then being blown to the room). The gas heated by the bigger room air temperature than extends back to the condenser where heat is removed and the cycle continues.
Both evaporator and condenser are sealed units and you can’t carry out any air conditioner repairs to these yourself: you must call a skilled professional. What you are able to do is to help keep everything clean and all the mesh guards and so on free from debris. You can carry out simple air conditioner service yourself, but not HVAC repair. Here are some basic air conditioner repair, troubleshooting and service tips.
1. System fails to run.
Check the fuses or circuit breakers. If they are fine then check heating and air columbia sc that the thermostat is not set too high. Try lowering it by 5 degrees, and if that fails you need a professional HVAC repair engineer.
Again, check the thermostat and try lowering it. If that doesn’t work check the condenser air intake. It could be blocked, especially in fall if there plenty of leaves flying about. Check the fins of the fan are straight, and if not then straighten them. If nothing works, then call a specialist engineer.
With this and other faults, all you are able to do is to clean the condenser it as far as you are able to, and if that fails call an engineer. It is not uncommon for units to be blocked by vegetation of just one form or another. The condenser will probably be sitting on a concrete pad: make sure that is level, because concrete can sometimes break up and put the condenser and the motor from the level. That could affect its operation.
The condenser and evaporator are sealed units, which it is why it is so difficult for amateurs to carry out their particular air conditioner repair. A blocked or dirty evaporator is the most frequent problem as possible fix yourself. When you yourself have a regular air conditioner service carried out by way of a professional then you shouldn’t experience these problems, except in extreme weather conditions when vegetation and other debris can be blown to 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 far better in the future to have a professional contract that looks after all this for you personally on a regular basis.
Frankly, notwithstanding those who try to accomplish it themselves, HVAC repair is a job for professionals if you prefer it done properly. If you test it yourself you not merely have the issue of getting into the units, and then a increased problem of effecting a secure repair, but you then have to place everything back together in a secure fashion.
It is advisable to utilize a professional air conditioner repair service, but one that first offers you a totally free estimate. Some charge for the estimate, so you’re obliged to pay for them whether you accept the estimate or not. You often realize that firms that give you a free estimate are both relatively expensive and execute a good job. No business are able to offer free estimates unless they are good at what they do and their costs are very competitive.
Also, make certain they offer you a guarantee – for time and any parts which they install. If your present system has to be replaced, also make certain they offer you a trade-in deal. They can use the parts in your old equipment, so don’t give it to them free. You is likewise advised to take a 24/7 service deal, since you don’t desire to be sweating when your HVAC unit stops working, and if you are a senior, look for a discount. You never know your luck!
