Before trying to transport out ac repair in your house or office, you will find certain facets of air con systems you should know about. When their air con system breaks down or develops a mistake, lots of people try to correct it themselves without fully understanding the concepts involved. However, it’s possible for you to carry out a basic ac service once you understand the principles, although HVAC repair (heating, ventilation and air conditioning) is better left to the professionals.
The standard home or office ac functions simple physics, and includes two discrete units: the condenser and the evaporator. In the condenser, Freon gas is put under great pressure then passed by way of a heat exchanger, removing heat from the gas and converting it to a liquid. It is then passed via an expansion valve in to the evaporator; the liquid Freon expands and evaporates to a gas, the latent heat required for this from the environment, which can be then cooled (the cooled air then being blown in to the room). The gas heated by the bigger room air temperature than dates back in to the condenser where heat is removed and the cycle continues.
The evaporator and condenser are sealed units and you can’t carry out any ac repairs to these yourself: you will need to call a skilled professional. What you are able to do is to help keep everything clean and all of the mesh guards and etc away from debris. You can carry out simple ac service yourself, although not HVAC repair. Here are a few basic ac repair, troubleshooting and service tips.
1. System fails to run.
Check the fuses or circuit breakers. If they’re fine then check that the thermostat isn’t 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 may be blocked, especially in fall if there a lot 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 can really do is to wash the condenser it in terms of 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: be sure that is level HVAC Columbia SC, because concrete can occasionally break up and put the condenser and the motor from the level. That may affect its operation.
The condenser and evaporator are sealed units, which it’s why it’s so problematic for amateurs to transport out their particular ac repair. A blocked or dirty evaporator is the most common problem as possible fix yourself. When you have a typical ac service carried out with a professional then you should not experience these problems, except in extreme weather conditions when vegetation and other debris may be blown in to the unit.
You can clean the evaporator unit yourself by first removing the insulation and the evaporator access plate, but it’s much safer and far better in the future to really have a professional contract that looks after all this for you on a typical basis.
Frankly, in spite of those who try to complete it themselves, HVAC repair is a work for professionals if you want it done properly. If you check it out yourself you not only have the situation of engaging in the units, and then your even greater problem of effecting a secure repair, but you then have to place it all back together in a secure fashion.
It is advisable to employ a professional ac repair service, but the one that first offers you a totally free estimate. Some charge for the estimate, so you are obliged to pay for them whether you accept the estimate or not. You often see that firms that offer a free estimate are both relatively expensive and perform a good job. No business are able to afford to offer free estimates unless they are good at what they do and their prices are very competitive.
Also, make sure they give you a guarantee – for time and any parts which they install. If your current system needs to be replaced, also make sure they give you a trade-in deal. They are able to use the parts in your old equipment, so don’t give it in their mind free. You will also be advised to have a 24/7 service deal, when you don’t want to be sweating whenever your HVAC unit breaks down, and if you are a senior citizen, request a discount. You never know your luck!
