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. When their air conditioning system breaks down or develops a fault, many people try to fix it themselves without fully understanding the concepts involved. However, it is possible for you to carry out a basic air conditioner service once you understand the principles, although HVAC repair (heating, ventilation and air conditioning) is best left to the professionals.
The normal home or office air conditioner works by simple physics, and consists of two discrete units: the condenser and the evaporator. In the condenser, Freon gas is put under pressure then 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 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 Aircon Servicing.
Both the evaporator and condenser are sealed units and you cannot carry out any air conditioner repairs to these yourself: you will have to call a trained professional. What you can do is to keep everything clean and all the mesh guards and so on clear of 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.
- System fails to run.
Check the fuses or circuit breakers. If they are fine then check 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.
- No Cooling.
Again, check the thermostat and try lowering it. If that doesn’t work check the condenser air intake. It might be blocked, especially in fall if there lots of leaves flying about. Check the fins of the fan are straight, and if not then straighten them. If nothing works, then call a professional engineer.
- Erratic Cooling
For this and all other faults, all you can really do is to clean the condenser it as far as you can, and if that fails call an engineer. It is not uncommon for units to be blocked by vegetation of one form or another. The condenser will likely be sitting on a concrete pad: make sure that is level, because concrete can sometimes break down and put the condenser and the motor out of the level. That can affect its operation.
The condenser and evaporator are sealed units, which it is why it is so difficult for amateurs to carry out their own air conditioner repair. 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 contract that looks after all of this for you on a regular basis.
Frankly, in spite of those that try to do it themselves, HVAC repair is a job for professionals if you want it done properly. If you try it yourself you not only have the problem of getting into the units, and then the even greater problem of effecting a safe repair, but then you have to put it all back together in a safe fashion .
It is advisable to use a professional air conditioner repair service, but one that first offers you a free estimate. Some charge for the estimate, so you are obliged to pay them whether you accept the estimate or not. You often find that firms that offer a free estimate are both relatively expensive and do a good job. No business can afford to offer free estimates unless they are good at what they do and their prices are very competitive Aircon Chemical Wash Singapore.
Also, make sure they give you a guarantee – for time and any parts that they install. If your current system has to be replaced, also make sure 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 will also be advised to take a 24/7 service deal, because you don’t want to be sweating when your HVAC unit breaks down, and if you are a senior citizen, ask for a discount. You never know your luck!
There is no doubt that having your air conditioner serviced is one of the most important things you can do. Since these items can help to control the temperature in your home, you are going to want to ensure that you have them in their peak working order. That means you are going to need to have a professional that can come out and service these items and help you to handle any problems before they come up as well.
One of the first things you are going to need to consider when you are looking to have your air conditioner serviced is the type of company you are going to need to come out. Depending on how your system is setup, you might need to have either a residential or a commercial company come out. These individuals are going to be trained in dealing with units that are commonly found on these styles of properties.
When the air conditioning service company comes out, they are going to do an inspection of the unit that you have. During their inspection, they are going to look for things like leaks, breaks in the hoses and other items that are going to end up costing you money and items that could potentially cause serious damage to your unit, if they are left unrepaired.
During their service call, the air conditioning service company is going to take the time to clean your unit as well. This will help to prevent the buildup of dust and other items from becoming a problem and affecting the unit. In some cases, they will do a deeper cleaning of things like the cooling coil, in the event that there is a need for such services to be done.
Keep in mind that while they are out there inspecting your unit, it is often a good idea to mention any problems you are noticing as well. This can be simple items like the system is taking longer to cool down or in some cases it is making noises. The individual doing the repair can then check the coolant levels and ensure that there is nothing loose or having problems inside the unit itself.
You will want to be sure that you are having regular air conditioning service done to your unit in an effort to avoid any problems from happening. To begin this process, begin by checking some of the local service companies in your local area and begin to check their pricing structure and what their service call entails as well.
