Modern HVAC systems are among your home’s most complex electrical devices. The system can develop electrical problems, especially during seasons of frequent use or due to poor maintenance. You may find it tempting to resolve the issue yourself if you have some knowledge of your cooling and heating system. But a mistake can cost you more, which is why professional electrical repair services would make a smarter choice.
What you can do is pay attention to your HVAC for the following signs of electrical problems:
1. Circuit Breakers that Frequently Trip
One of the typical signs of an HVAC electrical issue is a breaker which frequently trips. The common cause is an HVAC system that is inappropriately matched to your house’s voltage or faults in your circuit control board. Should you notice any burn or damage marks on the electrical panel, you should call an electrician at once.
2. AC Units that Won’t Turn On or Off
HVAC units that often do not turn off or on point to a problem with the relays. Electrical power cannot transmit to your system’s motors without relays. If your motor does not turn on, the relay might have been forced open. Motors that will not switch off point to relays which have sealed shut or become stuck.
3. Frost Development Inside Your HVAC
Development and accumulation of frost inside your air conditioner is a sign of contactor issues. The contactor is your HVAC unit’s power regulator. If the electrical relay gets stuck in an “on” position, your unit will operate at top capacity for an extended period. This drops the unit’s internal temperatures very low, causing condensation to freeze on the inside.
The numerous wires in your HVAC unit are susceptible to fraying, disconnection, and corrosion among other damage. This might create problems with the electric flow in your system and eventual shutdown. Regular professional maintenance of your unit is essential to prevent this problem.
