Preventing HVAC Systems from Power Surges

Ensuring that our homes are comfortable all the time is very important. To combat winter cold and summer heat, heating, ventilation and air conditioning systems also known as HVAC systems are very important. HVAC system is made of several units with the largest being the outdoor cooling unit. It has components such as air delivery devices, motors, boilers, terminals, heaters and chillers. All these components require electricity to function efficiently.


Power surges occur when electrical current is boosted above the optimum level at some point in the power line.


Strong thunderstorm produces lightning. The lightning can cause a chief risk to your HVAC system. Apart from the natural thunderstorm that can cause risks to the system, workers activities can also result to power surges and outages. The effects of surges on HVAC equipments can be detrimental. A power surge can impact negatively on the HVAC system as well as the equipments associated with it.


This calls for surge prevention as the results of the opposite are deadly. Although it’s not possible to control surges, there are precautions to prevent them from harming the HVAC system equipments.


Use Surge Protection


Surge protection is the process of ensuring that excess electricity is buffered if a power surge happens to occur. Whole home surge protection is a mile stone toward protecting the HVAC system and other appliances from damages caused by power surges. This protection is put at the point of entry of the main power line. Additionally power strips with surge protection capability can be used in each outlet. All HVAC equipments should be plugged into one power strip. Make sure that the surge protection in the power is functioning properly.


Make use of Time delay Technology


Power surges can also be caused by a power outage as the grid stabilizes. During stabilization process brief power spikes continue for a few minutes after power is restored to normal. If the HVAC system equipments happens to start instantly upon the reinstatement of power, these spikes could cause unprecedented damages. Using a thermostat with time delay technology will help in preventing the system from turning on instantly after power is restored. The technology will keep the system off for a few minutes, to allow the grid to stabilize before restarting the system.


Turn off the System


This is one of the easiest ways to prevent power surges from harming the HVAC system. Turning off the system at the circuit breaker or thermostat or both before a storm occurs. The HVAC system can be expansively damaged by a power surge if operating at the time when the surge occurs. Thus, turning it off will greatly reduce the damages that could arise If the air conditioning is on operation at the time of storm. It’s also advisable to turn off windows unit or room air conditioners and unplug them so as to prevent any damage by power surges for those who uses only the windows unit.


Upgrade Inadequate Wiring


Electrical systems built before 1980s were not designed to handle large voltage equipments. Some of the visible signs of insufficient wiring include frequent blown fuses, tripped circuit breakers and flickering or dimming light. Upgrading to the current wiring standards with the capacity to support equipment with high voltage consumptions can greatly help in preventing the surges.


Fix Overloaded Circuits


Many newer homes have the problem of overloaded circuits. Having a circuit with many small devices can cause power surges. To prevent HVAC system appliances from suffering from the damage, it’s important to establish a dedicated circuit for each big appliance and to partition rooms with multiple devices into split circuits.
