One of the best ways for home and business owners to boost energy savings, longevity of their HVAC unit and reduce humidity is to have a programmable thermostat.   You can reduce the risk of having HVAC service performed on your unit during the hottest times of the year with the use of a dependable, programmable thermostat.

Which is Best

  • A thermostat that is ON means the fan runs 24/7 even when the home is already at a comfortable temperature.
  • Auto means the fan will automatically turn on only when the temperature inside goes above or below the ideal set temperature.  Once the home reaches the ideal temperature the thermostat tells the system to turn off.

Using the ON setting has several disadvantages that can cost you money in the future with HVAC service:

  • Increased energy bill
  • Air filter clogs quicker
  • Blower fan breakdowns occur more often resulting in more HVAC repairs

Energy Savings

Programmable thermostats reduce the risk of wasted energy due to human error.  You can program the settings to work with your home’s heating and cooling system effortlessly.  According to ENERGY STAR, if you set your temperature back 7° to 10° for 8 hours you can save up to $180 on your yearly energy bill.  If your unit isn’t saving you money, an HVAC service call can locate what is making your system run harder and longer.  

Life Expectancy

A programmable thermostat can also increase the life expectancy of your HVAC unit.  With the unit set higher, the system doesn’t have to work as hard to maintain a lower temperature.  When an air conditioner has to constantly run to keep the home cool, it can wear down the compressor and lead to expensive HVAC repairs.  

Humidity

Some programmable thermostats on the market offer control of the humidity in your home.  The thermostat lets the HVAC unit know that even though the temperature inside is set to a comfortable degree, the humidity is still too high in the home.  The air conditioner will then kick on in order to control the humidity inside. HVAC repair will be necessary if humidity goes unchecked inside your home.

Investing in a good thermostat can offer you many benefits with your heating and air system.  Contact Edwards Heating & Air and see the different thermostat options available.
