Common Heating And Air Conditioning Problems

Heating and air conditioning units offer convenience through all the seasons. They make your living area or working area more comfortable by making adjustments to the room temperature to create a conducive area depending on what your current needs are. However, just like any other systems, they are prone to experiencing problems. While you might be able to handle some of the problems easily, you might require the intervention of HVAC professionals for more complex problems.

Blown up fuses – Fuses protect the motor or compressor as far as overheating is concerned. They are located in the evaporator coil and they are the first component that must be checked when a motor is going bad. Your technicians can handle the problems easily and fast.

Worn out contactors – Every unit has a total of three contactors in the condenser fan motor, blower motor and compressor and they make electrical connection during heating or cooling. It is possible for pitting and arcing to form on the contactor creating a problematic electrical current required to start the motor. It is a complex problem that your air conditioning repair provider might need to check into.

Capacitor burn out – It is used in running motors at speeds that are consistent and they are usually rated in microfarads. The start capacitors increase the starting torque of the compressor and when they burn out, they do not function as well. They will need to be replaced to have them running again.

Corroded gas valve – It meters the amount of gas flowing from the gas line to the unit and is only used during the heating season. Corrosion can leave it ineffective and a replacement will be required to have it functioning as usual.

Clogged filters – They are what usually lead to reduced air flow and thereby result in frozen units that won’t function right. Air particles and dirt can clog the filters and you will need to change them once in a while. If you hold the filter up and you can’t see the light passing through it, it is time to have it changed.

Thermostat issues – It is the device that controls the system on what it is supposed to do. In most cases, it is either set wrong or turned off and that is the reason why it does not function. You might want to consider checking your settings or whether it is on before calling in professionals when there is nothing really wrong with your unit.

Clogged drain lines – They can lead to the filling of the drain pan resulting in water leakage which can amount to water damages. Algae or dirt are the main culprits in clogging the lines and they will need to be cleaned out once in a while.

Refrigerant leaks – Unfortunately, leakages occurring in the evaporator coils or condenser are not possible to repair. They can occur as a result of the unit vibration during operation and might call for a total replacement of the unit. Leaks in other areas of the unit can however be taken care of by a qualified technician.

Air Conditioning Problems That Require Professional Services

A lot of people always try to cut back on any expense when they can, and hiring the professional services of an air conditioning technician is most of the time not an exception. With times getting hard today, such mentality is understandable. However, there can be a thin line between economy and compromise. Many people mistake entrusting a major air conditioning repair to a non-professional, sketchy repairman as a practical attempt, when it can actually turn out to be a huge financial mistake in the end.

Sometimes, we just have to know where to stop. We need to know where the boundary between being practical and being unreasonably frugal is. We can apply this in the decisions we make in regards to our air conditioning units. Should the time come that the air conditioning system at home needs to be seen and repaired by a qualified technician, the best thing to do is to make a wise investment by steering clear from futile, even damaging cost-cutting attempts.

While there are minor AC mishaps that can be fixed even by average owners, there are also those that require the skill and expertise of a well-trained and experienced air conditioning repair specialist. These are the problems that should be addressed immediately if total damage is to be avoided.

The following are some of the red flags indicating that your unit needs professional ac repair:

1. The compressor won’t start.
There are a number of reasons that may hinder the compressor from starting, among which is a short or burnt circuit, and a capacitor that has stopped working.

2. The unit has a leak.
Leaks in any unit can lead to a dysfunctional Freon, which is what keeps the cooling effect of the AC up. Low levels of Freon can be damaging especially if neglected for a long time.

3. A tripped breaker.
When the unit was not used for a very long period of time and is suddenly switched on, chances are the breaker will go off or ‘trip’. This is a problem that needs immediate attention and must be resolved promptly.

The aforesaid AC problems are only a few of the more serious ones that require professional help. In order to prevent these from happening, scheduling unit maintenance on a regular basis is the best thing to do. It is also more advisable to have a professional carry out such procedures, as it is easier for them to spot potential problems while they are at it. Meanwhile, those who prefer doing maintenance on their own must be more observant in terms of the functionality of their unit. If the unit starts making strange, whirring sounds, there could be an existing problem. Puddles of water under the unit may have leaked from the unit’s anterior portion and is also a sign to look out for. If you notice that there has been a sudden spurt in your electric bills for the past few months, then perhaps you need to check on the reasons why your ac has been having a higher working time.

In the end, keeping your ac unit to its smooth working condition is a collaborative effort both of the air conditioning company service, and yours.

Avoid These Air Conditioning Problems

When the weather gets warmer, you will want to run your air conditioner. Naturally, you will expect it to work as it should. But, like all items that have moving parts, your air conditioner may develop problems. If you do experience problems, it may be due to one of several common air conditioning problems.

Dirty Air Filter
The most common problem that causes air conditioners to not function properly is a dirty air filter. The air filter is an important part of the HVAC unit as it filters dust, pet hair and other particles that float around your house. The air filter catches these, keeping them from getting to the coils within the air handler. If the filter becomes too dirty, the air handler may freeze up. In this case, you will feel a distinct difference in the air temperature coming from the air conditioning vents. You may even see ice build-up on the coils and evaporator unit. The easiest way to avoid all these possible problems is to change your air conditioning filter at least one time per month.

Low Freon Level
Low freon is another common problem with HVAC units. Freon is necessary for your HVAC system to run. Since it is a gas, it can leak from the HVAC unit over time. You will need to find a licensed air conditioning specialist to add freon to your air conditioning system. It cannot be purchased without an HVAC license.

Thermostat not working properly
If your thermostat isn’t working properly, you won’t get a correct reading of the air temperature in your home. Thermostats are not too expensive. They can be purchased and installed by the homeowner. If you have problems with your thermostat, you may want to consider replacing your current thermostat with a programmable one.

Clogged Drain Line
Another common air conditioner problem is a clogged drain line. Your HVAC unit must drain to work properly. Sometimes, dirt can build-up in the air handler. This prevents the water to drain from the coils. If the HVAC system can’t drain the water, it may freeze-up the unit. Preventative maintenance can keep this from happening. When having your yearly HVAC inspection, be sure the technician checks that their isn’t too much dust and dirt in the pan under the air handler.

The best way to avoid the above common problems with an air conditioner is by having an annual inspection of both your condenser and air handler. Have the coils within the air handler cleaned. Have a qualified service person inspect the entire HVAC unit, including all connectors, wires and freon level.
