When a power outage hits, most people think about food in the fridge or losing Wi-Fi, but your HVAC system needs attention, too. Whether it’s summer heat or winter chill, sudden power loss can stress your heating and cooling equipment. The good news? With a little planning and a few smart moves, you can safeguard your HVAC system and avoid costly repairs once the power returns. The team at Tom’s Heating has put together some easy things you can do to prevent stressing out your Carrier® home comfort HVAC equipment.
Install a Surge Protector for Your HVAC System
Just like you protect your computer with a surge protector, your HVAC system needs the same kind of defense. A whole-home surge protector installed at the electrical panel shields all major appliances, including your furnace and air conditioner, from voltage spikes. This is especially useful when the power comes back on and surges through the system.
For added protection, ask your HVAC professional about dedicated surge protectors designed specifically for heating and cooling equipment. These work in tandem with your main panel to provide a buffer between your unit and damaging electrical fluctuations.
Shut It Down During the Outage
If you lose power, one of the first things you should do is turn off your HVAC system at the thermostat. This simple step helps prevent your system from kicking back on suddenly when the power is restored. It reduces the load on the system and lowers the chance of short cycling or mechanical stress.
Once the lights are back and power seems stable, wait a few minutes before turning the HVAC system back on. Let your other major appliances power up gradually first, then restart your heating or cooling. This gives your system a smoother start and avoids overloading your home’s electrical panel.
Use a Backup Power Source if Possible
If you live in an area where outages are frequent or prolonged, a backup generator can be a worthwhile investment. A standby generator connected to your home’s electrical system can keep essential equipment, including your HVAC system, running smoothly even when the grid goes dark.
Be sure the generator is properly sized to handle the load. Running an HVAC system requires a significant amount of power, and not all portable generators are up to the task. An HVAC technician or licensed electrician can help determine what size generator you’ll need for emergency use. Give us a call if you would like to explore what generator will power your HVAC system.
Keep Vents and Filters Clear
Power outages sometimes come with severe weather, wind, snow, or heavy rain. These elements can clog exterior vents or block airflow, especially if branches or debris pile up near your outdoor unit. After the storm passes, take a quick walk around your system. Make sure nothing is covering the intake or exhaust vents, and clear away leaves or snow that may restrict airflow.
Also, check your air filter. If your system tries to restart with a dirty filter, it could work harder than it needs to, leading to overheating or poor performance. A clean filter helps your system get back on track faster after downtime.
Stay Ahead with Preventive Maintenance
The best protection against damage from a power outage? A well-maintained HVAC system. Regular inspections ensure that wires are intact, parts are lubricated, and components are up to the task. During a seasonal tune-up, your technician can spot issues that might make your system more vulnerable during an outage.
Even if you haven’t had problems yet, a power outage can bring hidden weaknesses to the surface. Catching them early helps avoid larger issues later
