Air Conditioner Repair: What You Need to Know
Before trying to handle ac repair in your house or office, there are specific facets of method you must know about. When their ac system breaks down or develops a fault, many people try to repair it themselves without fully understanding the concepts involved.Thermador refrigerator repair However, it is possible that you should carry out a basic ac service once you understand the principles, although HVAC repair (heating, ventilation and air conditioning) is better left towards the professionals.
The standard office or home air conditioner works by simple physics, and consists of two discrete units: the condenser and the evaporator.Kenmore refrigerator repair In the condenser, Freon gas is put under pressure then passed through a heat exchanger, removing heat in the gas and converting it to some liquid. It is then undergone an expansion valve into the evaporator; the liquid Freon expands and evaporates to some gas, the latent heat needed for next in the environment, that is then cooled (the cooled air then being blown into the room). The gas heated through the higher room air temperature than dates back in to the condenser where the heat is taken away and also the cycle continues.
Both evaporator and condenser are sealed units and you cannot execute any ac repairs to these yourself: you'll have to call a trained professional. You skill would be to keep everything clean and all the mesh guards and so on free from debris. You are able to carry out simple air conditioner service yourself, although not HVAC repair. Here are some basic air conditioner repair, troubleshooting and service tips.
1. System does not run.
Look into 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 when that fails you need a professional HVAC repair engineer.
2. 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 from the fan are straight, and when not then straighten them. If nothing works, then call a professional engineer.
3. Erratic Cooling
For this and all sorts of other faults, all you are able really do would be to clean the condenser it as being far as you can, and when that fails call an engineer. It is not uncommon for units to be blocked by vegetation of 1 form or any other. The condenser will probably be located on a concrete pad: make sure that is level, because concrete can occasionally break up and set the condenser and also the motor from the level. That may affect its operation.
The condenser and evaporator are sealed units, so it is the reason why it's so hard for amateurs to carry out their own air conditioner repair. A blocked or dirty evaporator is the most common problem that you could fix yourself. If you have a normal air conditioner service completed by an expert then you should not experience these problems, except in extreme climate conditions when vegetation and other debris could be blown into the unit.
You can clean the evaporator unit yourself by first taking out the insulation and also the evaporator access plate, but it is much safer and more effective in the long run to possess a professional contract that looks in the end of this for you on a regular basis.
Frankly, regardless of those that attempt to get it done themselves, HVAC repair is a project for professionals if you would like it done properly. If you try it yourself explore have only the issue of getting in to the units, and so the even greater problem of effecting a secure repair, but then you need to put it all together again in a safe fashion.
You should use a professional ac repair shop, only one that first provides you with a free estimate. Some charge for the estimate, which means you are obliged to pay for them whether you accept the estimate or otherwise. You often discover that businesses that offer a free estimate are both relatively expensive and do a good job. No business are able to afford to offer free estimates unless they're good at what they do as well as their costs are very competitive.
Also, make certain they give you a guarantee - for time and any parts they install. If your current system has to be replaced, also make certain they offer you a trade-in deal. They are able to use the parts inside your old equipment, so don't give it to them free. You will also be advised to take a 24/7 service deal, since you don't wish to be sweating whenever your HVAC unit breaks down, so if you're an older person, request a discount. You never know your luck!
