Dryers are work against your AC and furnaces because they exhaust your conditioned air every time they are run. Next time you take out the garage, take a look up and at your walls and you will see your dryer exhaust vent. Remember that great smell of doing laundry? That’s from your dryer exhaust fan. They are one of the highest exhausting appliances you have depending on how big your kitchen exhaust fan is. Dryer will pull anywhere from 100 CFM on the low side to 230 CFM on the high side. This can be potentially a health and safety hazard if you have an attached garage or gas appliances for potential backdraft of carbon monoxide and something your energy auditor will inspect.
An air conditioner is typically sized for 400 sq ft per ton. That means if you have a 1600 sq ft home, your AC should be around 4 tons. However, when the dryer is running, it is undermining your AC system by almost half a ton. So that 4 ton unit actually becomes a 3.5 ton unit with the dryer running.
Dryers typically run off of 240 volts and have a special outlet dedicated just to the dryer. It is best to hire a qualified electrician to add the proper voltage to the garage or outside.
For gas models, be sure the gas line is shut off when you disconnect the dryer and talk to your plumber about tapping into your barbeque gas line for the dryer or water heater line in the garage.
Here are some DIY steps to help you take the leap and the dryer.
I should also note that not using your dryer at all and buying a clothes line or drying rack will save you even more money and a few hours in the desert sun will dry your clothes without fading them.
The average family washes about 400 loads per year and 2.3 kWh/load. That equates to $92 a year for laundry, not including the air conditioning lost from the exhaust vent.
