4 Common HVAC Problems

There are some unique problems with the HVAC systems. As such, whenever you realize an anomaly in the HVAC unit, it is prudent to consult or reach out for professional air conditioning repair san diego When is one supposed to call them? The following are the four most common problems that necessitate working with an HVAC contractor.

No airflowair conditioning

Lack of airflow seems to be the most common problem with various HVAC systems. This can be attributed to two different reasons. The first and easiest to solve is a dirty air filter. As the air flows through the house, it gathers dust and dirt. The filter cleans this gunk out of the air. As more dirt is captured, it becomes hard for air to flow through the filter.

Another problem is a bad fan. The fan is responsible for moving the air through the system and out to the house. If the motor has burned out or there is a faulty wire connection, the fan cannot spin and move the air.

The air may not be cold enough

There is nothing worse than the warm air coming out of the vents in the summer. This can be caused by low amounts of refrigerant in the system. As the air flows over the cooling coils, it is cooled by the coolant. Low levels make it harder to get the air cold enough to make a difference.

Alternatively, the outside temperature is too high for the heat being taken out to dissipate enough. The refrigerant flows through the exterior coils but is still cooler than the ambient temperature outside. The coils can not coil the liquid off enough before heading back to the compressor.

Nothing quite beats the feeling of coming into a warm house in winter time. As with the air conditioner, sometimes the system does not heat the air up enough to create a comfortable temperature. With an electrical system, there may be a bad connection that keeps the heating element from heating up. Or, a flame system may not have enough fuel getting to the burners to keep a steady flame.

Abnormal utility bills

Often, high utility bills are caused by a lack of efficiency in the system. As the HVAC units age, they have to work harder to keep the correct temperature flowing to the rooms. But, lots of energy is consumed in homes that are not sealed or insulated properly. Any cracks in the exterior shell are a great place for warm air to move in during the summer or out in the winter. Lack of insulation in the walls and ceiling allow the heat to radiate through.…
