Controlling Room Temperature in Your Home

Posted on The Cooler Blog April 29, 2013

Maintaining the inside temperature of your home is an effective way of ensuring the heating costs stay low during the winter. It’s important to maintain your heating system – certain steps can help you troubleshoot problems instantly and maintain constant temperature without straining the A/C system.

Why monitor the temperature of my home?
Similar to gas and electric ovens, heating systems cycle on and off to maintain a steady temperature. A home thermostat operates on a closed control loop: it reads the temperature, assesses whether this number is higher or lower than the set temperature, and boosts or reduces power to match the number. If the temperature in your home rises and falls by even a few degrees throughout the day, the problem could be with your heating system.

Key checkpoints for controlling room temperature:

  • The actual temperature. Our perception of temperature depends on varieties of factors, but you could be over- or under-estimating the temperature in your house. Even if your thermostat has a thermometer, it’s a good idea to place another thermometer in the center of the room to determine the actual temperature.
  • The thermostat. When was the last time you replaced or repaired the home thermostat? If your thermostat is out-of-date, it’s time to replace it for a more modern digital model. A thermostat issue can be diagnosed by a heating and cooling specialist.
  • The furnace defrost cycle. Depending on the location of your home’s furnace, extremely cold temperatures with high humidity can cause frost to form on the heating coils. Your furnace should have a defrost cycle to remove frost from coil piping packages; if frost fails to melt, have a repairman look at your furnace.
  • A balanced system. Your heating water distribution system is said to be “in balance” when the flow measurements for the system match its specifications. An out-of-balance system means that water will be unevenly distributed throughout the house, sending more heat to some rooms and causing the system cycle to be more irregular. Even heat distribution means less energy used, so talk to a specialist about automatic balancing or control valve suppliers that can equip your system with more efficient valves.
  • Windows and doors. Check that all windows and doors are closed and properly sealed around the edges. Sealing caulk is a low-cost solution and it’s also beneficial to check the attic ventilation system.
