Normal Problems In AC Unit Repair

By Gaynell Blow


Spring is the most appropriate time to diagnose your HVAC system for any possible repair problems as this is the time when you require cooling the most. Unfortunately, we seem to impart less attention to the subject of global warming even if the northern states has already received hot temperature reports in the summer. The older and those with certain medical conditions are at greatest risk when the heat index climbs too high, but such days are a danger to those in all states of health without sufficient cooling measures at home and at work. So, before everything becomes too late, it is best to look at the following problems that everybody has faced:

The Unit Will Not Power On

When the air conditioner simply refuses to turn on, the trouble could be embarrassingly easy or an indication that a replacement is in order. If the unit is being tried for the first time, the HVAC contractors may have made a mistake in installation, or the unit might be defective. If in the late operation, the units can be powered "on" but no longer operates afterwards, it can be wiring problems. The most obvious, and frequently overlooked, trouble is a tripped circuit breaker. Many panicked people have called for air conditioner repair when a fast check of the breakers would save the ac repair man time and the customer's funds.

Circuit Breaker Trips Upon Turning Unit On

When you notice that there has been trips on the circuit breaker, it is time to give HVAC contractor a call to check the problem. Prepare to spend some cash when the breaker itself requires replacement. This is why it is imperative not to choose for inexperienced technicians who could have made mistakes in the installation or in the motor condenser. More pricy yet is a grounded compressor. In these circumstances, early detection so the trouble can be solved in time to enjoy a pleasant temperature in summer's worst humidity and heat. Seeking qualified HVAC contractors to guarantee that installation and grounding are done well in the first place is preferable to avoid the need for air conditioning repair.

Your Unit Operates But, They Are Not Cooling

When ac repair is called for because the system will not cool even though it is running, the causes are widely varied. If you hear humming but the fan inside is not even running, your motor might have gone bad or there could be problems with your wire and capacitor. If it is the other way around (fan is running but the compressor does not), start capacitor might be the cause of the problem or the compressor itself got technical problems. In this issuance, potential HVAC repairs include cleaning the condenser coil, replacing the compressor, and adjusting the refrigerant charge.

Presence Of Water In The House Due To System Leaks

Moisture can be a life threatening to your AC units, this is why you need prompt action when leak seems to exhibit in your units. When left unnoticed or unaddressed, water leaks can cause structural damage and encourage the growth of health-threatening mold and mildew. This issue commonly occurs because your units got problems with the stopped up drain. However, if there is nothing wrong with the drain, it could be that your evaporator coil has rusted. In this case, repair requires more planning and action which can also become very pricey. Lastly, you can let the whole unit be frozen up.

Indications that Refrigerant is Low

Most experts are hired because of low levels of refrigerant in the units. A unit that runs constantly, for example, quite possibly needs to be recharged. Refrigerant problem normally starts when ice starts to show at the condenser or in the lines. Although this issue might also be caused by a dirty evaporator or blower, most contractors find the root of the problem in the lack of cooling chemicals. Recharging of the system and diagnosing of potential leaks are the two most usual approaches to fix the refrigerant issue. However, if you allow the trouble to continue given that there have been a lot of Freon exhausted, compressor trouble will follow.

The above problems with your AC units make HVAC technicians very important. They are those who are capable in replacing and repairing your AC units. When problems are not detected early and addressed properly, the unit is most likely to break down when it is needed most, because that is when it will have to work the hardest. Early diagnosis on potential faulty wiring or clogged drains are simple things but, can already make a difference to your HVAC systems at home. A prompt check in the early warm days of spring will allow any vital ac repair to be handled well before an emergency arises.
