Tracy, if the freezer is in a freezing cold garage, it is definitely not using a lot of power in the wintertime. The summer might be different. We went through this 12 years ago when we were converting out house over to solar and wind power. I would highly suggest getting a watt meter instead of guessing and arguing about it, or asking hacks like me online. The most popular model is the Kill-A-Watt. In years past you had to order them online, but I saw one in our local hardware store last week for $29 USD. It looks like a lamp timer, you plug it into the outlet, then plug in the appliance in question, and leave it for a week. It has a digital readout that tells you how many watts it is using currently, and at the end of your week, or month, or whatever period, it tells you how many kilowatthours (kwh) it has used. Then you zero out the meter, and plug something else for a week. Some models even have programmable features where you can punch in your electric rate from your electric bill, and it spits the answer out in dollars and cents.
We clocked all the appliances and lighting in our home and made some interesting discoveries, like how much power our entertainment stand uses even when nothing is turned on, or the aquarium pump, cell phone charges left plugged in 24/7, and so on. There won't be any arguments anymore.
This won't speak for items like furnace blowers and well/sump pumps that don't have a cord on them. If you do have a sump pump with a cord, plug it in as well. But here is a neat thing you can do. Turn off every circuit breaker in your box except for one known circuit, like the bathroom. Now go examine the electric meter on the outside of your house. The disc should be motionless. If it is spinning, and nothing in your bathroom is on, then you might have a short circuit, or a faulty meter. If it is working properly, then plug in a known large power using hand held device, like a hair dryer, or electric heater, and run it on high. While it is running, go look at the meter again with a watch. See how many times the disc goes around in one minute with just that hair dryer going. Let's assume it spins 6 times, and the hair dryer is 1200 watts. You know that the meter turns one time per minute for each 200 watts of use. Now have someone go back to the circuit box and turn on one thing at a time while you watch the meter. See which circuits coming back on make the disc spin fast. I would suspect the furnace if it runs, but your fridge might be suspect if it is an older model, or perhaps you have a plug in appliance malfunctioning, like a curling iron, bad ceiling fan, or who knows. At least this way you might have an idea which circuit is using the most, and can narrow down your search. Good luck Tracy, and take care, Rudydoo
