There are some things you need to know before you attempt to repair your air conditioner in your house or office. Many people attempt to repair their air conditioners themselves when it breaks down or becomes defective. Although it is possible to perform basic air conditioner maintenance once you have a good understanding of the principles, HVAC repair (heating and ventilation) should be left to professionals.
The basic physics of an air conditioner for home or office is simple. It consists of two separate units: the condenser (or evaporator). The condenser uses Freon gas to create pressure. It then passes through a heat exchanger that removes heat from the gas and converts it into a liquid. The liquid Freon is then passed through an extension valve into the evaporator. It expands and becomes a gas. The environment provides the heat necessary for this process. After cooling, the cooled air is blown into the room. The higher temperature of the room causes the gas to heat. It then goes back into the condenser, where it is removed from the heat.
The condenser and evaporator are sealed units. You cannot repair them yourself. A trained professional will do it for you. You can clean the condenser and condenser and keep all mesh guards, etc. clear of any debris. Simple air conditioner repairs can be done by you, but not HVAC. These are basic tips for air conditioner troubleshooting, repair and maintenance.
1. The system fails to start.
Make sure you check the circuit breakers and fuses. If the fuses or circuit breakers are in good condition, then make sure that the thermostat setting is not too high. If that fails, you can lower the thermostat by 5 degrees.
You can also check the thermostat to see if it is low enough. If this doesn’t work, check the condenser intake. If there are many leaves around, it might become blocked in fall. Make sure the fan’s fins are straightened. If the fan doesn’t work, call a professional engineer.
This fault, as well as all others, can be fixed by cleaning the condenser as best you can. If that fails, call an engineer. Units can become blocked by vegetation. Condenser units will be placed on concrete pads. Make sure the concrete pad is level. Concrete can sometimes crack and cause motor and condenser to fall out of place. It can also affect the operation of the condenser.
It is difficult to repair your air conditioner by yourself because the condenser is sealed and the evaporator is not. The most common problem you can repair yourself is a blocked or dirty condenser. These problems can only be caused by poor maintenance.
Although you can clean the evaporator unit by yourself, it is safer and more efficient to hire a professional contractor who will take care of all the details on a regular basis.
HVAC repair, despite the fact that many people try to do it themselves is best left to professionals. You will not only face the problems of getting in the units and the more difficult task of repairing them safely, but you also have to put the pieces back together in a safe manner.
A professional service is recommended, but it is best to get a free estimate. There may be a charge for an estimate. You will have to pay them regardless of whether or not you accept it. Many times, you will find that companies that provide a free estimate are not only expensive but also do a great job. If they are skilled in their field and have very low prices, no business can afford to provide free estimates.
Make sure you get a guarantee for the time and parts they use. You should also ask for a trade-in offer if your system needs to be replaced. They will accept the parts from your old equipment. Don’t give them anything for free. It is a good idea to get a 24-hour service contract, as you don’t want your HVAC unit to break down. Senior citizens can also ask for a discount. You may be surprised at what your chances are!
