What is the most efficient setback for my programmable thermostat?

A programmable thermostat helps make it easy for you to save by offering four pre-programmed settings to regulate your home's temperature in both summer and winter - when you are home, asleep, or away. image of a programmable thermostat

The pre-programmed settings that come with programmable thermostats are intended to deliver savings without sacrificing comfort. Depending on your family's schedule, you can see significant savings by sticking with those settings or adjust them as appropriate for your family.

However, these rules change for heat pumps and alternative systems such as geothermal. Fortunately, many of the latest programmable thermostats have smart settings for these alternative systems.

The key is to establish a program that automatically reduces heating and cooling in your home when you don't need as much. Use the programmable thermostat calculator to see what you can save with set-back temperatures that work for your family. The pre-programmed settings for a programmable thermostat are:


The average household spends more than $2,000 a year on energy bills - nearly half of which goes to heating and cooling. Homeowners can save about $180 a year by properly setting their programmable thermostats and maintaining those settings.

How often do I need to tune & clean my furnace?

Echols and the equipment manufacturers recommend yearly checks on your equipment (at a minimum, every 2 years). All equipment needs checked for safety and cleaned routinely.

My throat and nose get very dry at night - is there anything I can do?

Installing a whole house humidifier is the best way to prevent this problem. It will also eliminate static in the house and make the home more comfortable for you.

How often should I change my filters in the furnace?

If you have a standard disposable filter, you should change them monthly. If you have an electronic filter, they must be cleaned monthly for maximum efficiency. If you have an enhanced filter media air cleaner (such as an Aprilaire  Spacegard), the manufacturer recommends yearly changes unless you have unusual circumstances in your home.

Why should I buy a high efficiency furnace?

Cost of operation will be cheaper than a low efficiency furnace. This is a return on your investment. There are many options available with the newer furnaces that not only make operation less expensive, but allow you much greater comfort in your home.

What is Carbon Monoxide (CO)?

CO is produced by the incomplete combustion of fuels- it is odorless, colorless but toxic - all burning applicances have the potential to produce carbon monodide -Carbon monoxide can result from improperly vented or malfunctioning combustion applicances such as furnaces, stoves and water heaters. We recommend using a carbon monoxide detector in your home.

Why should I have a night set back (Programable) thermostat?

The government estimates you can save as much as 10 percent a year on your heating and cooling bills by simply turning the thermostat back 10 to 15 percent for 8 hours during a 24-hour period.  That means that during the heating season, if you turn the heat down when you go to bed at night or leave for work, you save 10 percent.
