"My husband owned his own A/C business for a long time....he said everything on here is the PROPER way to do this.....do it yourself, will make unit not work so hard and you save $ by not paying the A/C company!" Our electric bill rose to $430 two years ago and a simple A/C cleaning lowered it to $150."
The appliance repairman told me using the self-cleaning feature takes years off the life of an oven. The best oven cleaner! Cover bottom of oven with baking soda, then pour vinegar so it's all wet. Let sit around 20 minutes or so then wipe all of it out with damp cloth or sponge. I leave my oven door open too. After drying you may see some white residue, wipe again. Good to know
