HVAC Repair South Pasadena, CA

A client in South Pasadena, CA, had issues with their home’s air distribution system, so they called our Pioneers Heating and Air team for help. It had been like that since they installed their AC. Another company had already replaced the faulty parts and rewired the entire board, but with no progress. Upon further inspection, we noted that the zoning control panel received power and all zone dampers opened and closed correctly. And so, we knew that the problem could only be due to an undersized zoning board transformer. We replaced it with the correct size needed to power all dampers, and everything worked properly again. The client was more than happy that our HVAC repair solved their problem.

Sizing a transformer for a zoning system is one of the most neglected parts of designing HVAC zoning systems. While it may not seem like much work when designing your panel and ducting, oversizing or undersizing the transformer can make a real difference in your system. Oversized transformers can be difficult to work with and are a fire hazard. On the other hand, when transformers are undersized, the power that flows through zoning panels can be unstable and cause damage. Eventually, this power surge can cause equipment to malfunction and break down.

How Does a Zone Control System Work?

A zone control system is a type of climate control system. It allows you to individually regulate the temperature and humidity in every room of your house. This system divides the home’s floor area into multiple zones and controls the climate within each one separately. The airflow to each area is managed using dampers, which open and close as needed. Setting the thermostat in each space makes it possible to create perfect temperatures and humidity levels.

Common Problems in Zone Control Systems

Damper Issues

These pieces of mechanical engineering open and close ducts in response to signals sent by the thermostat. Automatic dampers control each zone’s airflow, with the controller determining which parts need more or less air depending on usage. When one room is not active, these devices will remain firmly shut. When dampers do not function properly, it can cause major disruptions in airflow through the ducts. Often, this is due to dirt and dust buildup over time. So to avoid these issues, routine HVAC system maintenance is essential for seasonal efficiency.

Defective Thermostats

Temperature control is critical in any zoning system, and the thermostat is essential. This vital component communicates with the dampers to ensure proper air circulation through ducts. Unfortunately, when the thermostat malfunctions, it can lead to inefficient regulation of temperatures throughout your home. As a result, specific parts of your home may experience uncomfortable temperatures and higher energy expenses.

Control Panel Malfunctions

An essential aspect of zone-control systems is a reliable control panel. It is responsible for interpreting signals sent to duct dampers and communicating with thermostats to ensure conditioned air flows to every zone. However, should something happen to this unit, it could result in certain zones not getting proper ventilation.

Leaky Ducts

Ducts that are not sealed properly can lead to several issues with temperature control and air conditioning. When the ductwork is not sealed tight, it can cause an imbalance in pressure between different parts of the house. That leads to harmful air being pulled into your home, such as carbon monoxide from a gas furnace and moisture from outside. These issues then force your AC system to work harder than necessary.
