Ready to Invest in a Whole House Generator?

Ready to invest in a whole house generator? “Is it really worth the extra money” is a question people often ask us. “What about the portable generator I saw yesterday on sale, why won’t that work for me?” is another. 


These are great questions. We hear them every day. Searching the internet for advice doesn’t really answer all of your questions, however.  Here are 3 important things to know before you buy a whole house generator: 

  1. No surprise, central air conditioning and HVAC systems are power hungry units that directly affect size, or capacity of a whole house generator. Generators are measured in kilowatts: 1kW = 1,000 watts. If an A/C unit is 36,000 BTUs that means you need a whole house generator of at least 11kW.
  2. What type of fuel do you need? Whole house generators of up to 22kW run on liquid propane (LP) or natural gas (NG). If you’re thinking of buying a whole house generator that runs on diesel fuel, you’ll need to bring your budget way up for a liquid cooled whole house generator. Meter and gas lines must be the correct size for NG, and both LP and diesel whole house generators need tanks large enough to support continuous operation. Speaking to an expert about your specific situation is always the best way to identify options.
  3. Getting the right switch – known as the Automatic Transfer Switch (ATS) is just as important as selecting the right whole house generator because they work together to restore lost power. Your electrical service panel will tell you if you have a 400, 200 or 100 amp service. Most average sized homes are 200 amp, so you’ll need a 200 amp transfer switch.
