HVAC

At David White Services, we know that power outages can disrupt more than just your lights. When electric power is interrupted, your HVAC system also stops functioning, often in ways that can cause stress to both your equipment and your comfort.

Read on to understand how outages affect your HVAC and share steps you can take to protect your system.

Effects of Power Outages on HVAC Equipment

When your HVAC system loses power, the following issues may arise:

  • Refrigerant line stress: Sudden shutdowns can lead to refrigerant pressure changes that strain compressors.
  • Frequent cycling: Rapid on-off cycles during intermittent outages may wear down motors and electrical components.
  • Surge damage: Restored power can bring voltage spikes capable of damaging fans, circuit boards, and thermostats.
  • Frozen coils: If cooling stops suddenly, moisture can collect and freeze on coils when power returns.

How to Prepare Your HVAC System for Power Interruptions

Here are proactive measures to protect your equipment and maintain comfort:

  • Install a surge protector: Whole-home surge protectors or HVAC-specific units absorb voltage spikes and safeguard electronics.
  • Use a standby generator: This ensures continuous power during outages, protecting both comfort and system integrity.
  • Enable thermostatic delay: Allow your thermostat to delay system startup after power restoration to reduce compressor stress.
  • Monitor regularly: During power restoration, monitor system performance, listen for unusual sounds, and review thermostat operations.
  • Schedule preventive maintenance: Regular annual inspections by David White Services help identify weak components before an outage strikes.

Recovery Steps After an Outage

  • Wait before powering on: After power returns, wait a few minutes before resetting breakers to allow pressure to stabilize.
  • Reset smart devices: Disconnect and reprogram Wi-Fi thermostats, smart vents, or zoning equipment as needed.
  • Check filters and drains: Inspect air filters and condensation drains, and clean or replace as necessary.
  • Watch for odd behavior: Pay attention to unusual noises or lack of airflow. Contact David White Services if you suspect an issue.
