Honeywell home Thermostat

It’s Spring here in Knoxville, you will likely find yourself changing your thermostat setting from heat to cool and back to heat on the same day. Last week, we had a few days of warm weather that spurred a rash of service calls. Homeowners were turning their HVAC system to cool for the first time in months and found that their system wasn’t reaching the desired temperature. Here are a few tips for for your Spring thermostat setting.

Should my Thermostat be on Auto or On

The auto setting varies in function thermostat to thermostat.

Will Frequently Switching from Heat to Cool Hurt My System

Thermostat Circuitry

Your heating and air system is designed to switch back and forth to maintain home comfort. Generally, it is safe to switch from heat to cool and vice versa on the same day. There is no need to tough it out. If your home is uncomfortably warm, turn your system to cool for a few hours. It shouldn’t be a problem. Just be sure to:

  • Not to shift it back in forth too often.
  • Avoid switching back and forth in the same hour.
  • Allow your unit to complete its current cycle before making the switch
  • Allow the compressor to shut off entirely before changing the thermostat setting and temperature.
  • Pay attention to how your system runs during the switch

How Do I Know Something is Wrong

Watch out for these signs that there may be a problem:

  • The air conditioner/heater fail to meet the thermostat setting
  • Supply vents blowing cold air when the heat is on and vice versa
  • The heating and air conditioning system frequently trips the breaker
  • The unit constantly running whether heating or cooling
  • The unit does not turn on when you think it should
  • Unit is short cycling

Short Cycling

When your heating and air conditioning system engages frequently, but for short intervals, it is called short-cycling. Short-cycling will significantly reduce your system’s efficiency and shorten its lifespan. You can potentially short-cycle your unit if you do not allow it to complete its cycle before switching from heat to cool. If your unit is short-cycling on its own, it is vital you contact a professional HVAC technician as soon as possible.

Maintenance is the Key to HVAC Efficiency and Longevity

If your system is struggling or showing the above signs, it is almost certainly the result of a poorly maintained or aging unit. Short-cycling and other HVAC issues are magnified when heating and air conditioning systems are not properly maintained. Take these few maintenance steps now to ensure your system will be ready for the coming season:

  • Regularly change your air filter.
  • Check for leaks around the unit, indoor and outdoor.
  • Remove debris and maintain proper clearance around the unit.
  • Keep vents open and unobstructed.
  • Clean outdoor unit fan.
