Programmable thermostats allow you to have the temperature raise and lower automatically at specific times each day. They will reduce your energy bills and increase your comfort (ie. get up to a “warm” bathroom during the winter). If your family follows a fairly regular schedule, a programmable thermostat will pay for itself in a few months.
What about a new humidifier?
Aprilaire humidifiers are great! They reduce dry skin and especially help with dry sinuses. They help reduce colds and allergies. They also help furniture from drying and eliminate shock from static electricity. We have several models available and the investment is surprisingly low.
