Power outages got you sweating? here’s how to keep your ac running with a generator
What To Know
- The output power of a generator must exceed the starting watts of the air conditioner to ensure it can start successfully.
- Choose a generator with a power output that exceeds the starting watts of the air conditioner.
- Calculate the total starting and running watts of all the air conditioners you want to run and compare it to the generator’s power output.
When faced with power outages, the question of “can I run air conditioner with generator” often arises. Air conditioners are essential for maintaining comfort during hot weather, but they also consume a significant amount of electricity. Understanding the compatibility between generators and air conditioners is crucial for ensuring a reliable cooling solution during emergencies.
Understanding Generator Power Requirements
Before determining if you can run an air conditioner with a generator, it’s essential to understand the power requirements of both appliances.
Air Conditioner Power Draw
Air conditioners have two key power ratings:
- Starting Watts (or Amps): The initial surge of power required to start the compressor.
- Running Watts (or Amps): The continuous power needed to operate the air conditioner once it’s running.
Generator Power Output
Generators are rated in watts or kilowatts (kW). The output power of a generator must exceed the starting watts of the air conditioner to ensure it can start successfully.
Can I Run Air Conditioner with Generator?
The answer to this question depends on the specific generator and air conditioner models you have. Here are some general guidelines:
Small Window Units (5,000-8,000 BTU)
- Most small window units can be run with generators rated at 2,500-3,500 watts.
- Ensure the generator’s starting watts exceed the air conditioner’s starting watts.
Central Air Conditioners (12,000-18,000 BTU)
- Central air conditioners require more power and typically need generators rated at 5,000-7,500 watts.
- Consider a higher-wattage generator for older or larger units.
Inverter Generators
- Inverter generators produce a cleaner and more stable power supply, making them ideal for sensitive electronics like air conditioners.
- Choose an inverter generator with a power output that exceeds the air conditioner’s starting watts.
Hard Start Kits and Soft Starters
Some air conditioners, especially older models, may require additional devices to reduce their starting power draw.
- Hard Start Kits: These capacitors store energy and release it during startup, reducing the initial surge of power.
- Soft Starters: Electronic devices that gradually increase the power to the air conditioner, reducing the starting load on the generator.
Safety Precautions
When running an air conditioner with a generator, it’s crucial to follow these safety precautions:
- Use a generator rated for the power requirements of your air conditioner.
- Ensure the generator is properly grounded and connected to the air conditioner.
- Never run the generator indoors or in enclosed spaces.
- Place the generator in a well-ventilated area away from windows and doors.
- Monitor the generator’s fuel level and refill it as needed.
Recommendations: Ensuring Comfort During Power Outages
By understanding the power requirements of your air conditioner and choosing a compatible generator, you can ensure a reliable cooling solution during power outages. Remember to follow safety precautions and consider additional devices like hard start kits or soft starters if necessary. With proper planning and execution, you can maintain a comfortable indoor environment even when the power goes out.
Popular Questions
1. What size generator do I need for my air conditioner?
The generator size depends on the air conditioner‘s starting and running watts. Choose a generator with a power output that exceeds the starting watts of the air conditioner.
2. Can I use an inverter generator for my air conditioner?
Yes, inverter generators are ideal for sensitive electronics like air conditioners. They provide a cleaner and more stable power supply.
3. Do I need a hard start kit or soft starter for my air conditioner?
Older or larger air conditioners may require a hard start kit or soft starter to reduce their starting power draw.
4. How do I connect my air conditioner to a generator?
Use a heavy-duty extension cord rated for the power requirements of the air conditioner. Connect the extension cord to the generator and the air conditioner.
5. Can I run multiple air conditioners on one generator?
It depends on the power output of the generator. Calculate the total starting and running watts of all the air conditioners you want to run and compare it to the generator’s power output.
