The Main Causes of a Broken HVAC Unit

Aug 21, 2015

Major Causes Of Broken HVAC Units

HVAC is a complex system that is responsible for heating, ventilation and air conditioning at home. It provides a fresh and relaxed environment that is comfortable and conducive. However, all this can be interrupted if there is a flaw in the system.

The following are the 5 major causes of a broken HVAC unit.

1. Broken Thermostat

A broken thermostat causes extreme temperatures in the affected home. An easy way to confirm that yours is broken is by changing the setting to the opposite effect. If it is set to produce heat, then change it to cooling.

If there is no change after some minutes, then it is faulty. Some of the reasons that cause the problem include loose wires and screws, blown fuse or poor quality batteries among others.

2. Imbalanced Dampers

Dampers are located in the air vents to control airflow from one home to next. When the dampers are imbalanced, then a room will heat or cool faster compared to another.

As a result, one is forced to endure harsh temperatures and excess moisture that leads to the growth of mold and mildew.

To fix the problem, the dampers should be adjusted to obtain the required balance so that all rooms receive equal cooling or heating.

3. Leaking Refrigerant

For one to receive cool air in their home, then the cooling unit is essential. A typical condenser unit must have a liquid refrigerant to generate cool air. If the system has less liquid refrigerant, then the produced air will not be as cool as it should be.

High temperatures will be experienced and if the issue is ignored, the condenser is overworked causing more problems later.

4. Dirty Filters

Dirty filters can cause massive problems to your Greenwood HVAC system forcing you to spend more on repair. It is important that you use the appropriate filter that is compatible with your system.

You can always seek expert advice from a professional to show the right filter, how to remove and replace it. Temporary filters should be replaced monthly especially during peak seasons. If you have permanent ones, then it is recommended that you clean them every month.

If your Greenwood home filter is dirty, all that passes through is contaminated. This means that the air you breathe is harmful. You may also experience reduced airflow, which leads to difficulty in breathing.

5. Tripped Circuit Breaker

The circuit breakers in HVAC rarely trip unless there is a serious problem. Although if the furnace or the condenser is faulty then check the breaker. The issue can be solved by flipping the switch off then on again.

If the situation is recurrent, then you should consult with a specialist. The tripping means that the breaker is preventing high voltage or temperatures that can damage wires and eventually cause a fire.
