Tip & How-To about Heating & Cooling

Air Conditioning Tips & Tricks You Must Know!

  • Try setting your thermostat between 72°F and 78°F. Each degree setting below 78°F will increase your energy consumption by approximately 8%. As you can see, that can add up to a lot of money over a year.
  • Inspect and clean both the indoor and outdoor AC/Heating coils. The indoor coil in your air conditioner acts as a magnet for dust because it is constantly wetted during the cooling season. Dirt build-up on the indoor coil is the single most common cause of poor efficiency. The outdoor coil must also be checked periodically for dirt build-up and cleaned if necessary.
  • Check the refrigerant charge. The circulating fluid in your air conditioner is a special refrigerant gas that is put in when the system is installed. If the system is overcharged or undercharged with refrigerant, it will not work properly. You may need a service contractorto check the fluid and adjust it appropriately.
  • Use bath and kitchen fans sparsely when you are running the air conditioning system.
  • Reduce the cooling load by using cost-effective conservation measures. For example, effectively shade east and west windows. When possible, delay heat-generating activities, such as dishwashing or baking, until the evening on hot days.
  • Try to not use a dehumidifier at the same time your air conditioner is operating. The dehumidifier will increase the cooling load and force the air conditioner to work harder, which in turn increases your utility bill.
  • Over most of the cooling season, keep the house closed tight during the day. Don’t let in unwanted heat and humidity. If practical, ventilate at night either naturally or with fans.
Room Air Conditioning Units
  • The unit should be level when installed, so that the inside drainage system and other mechanisms operate efficiently. If possible, install the unit in a shaded spot on your home’s north or east side. Direct sunshine on the unit’s outdoor heat exchanger decreases efficiency by as much as 10%. You can plant trees and shrubs to shade the air conditioner, but do not block the airflow.
  • Set the fan speed on high, except on very humid days. When humidity is high, set the fan speed on low for more comfort. The low speed on humid days will cool your home better and will remove more moisture from the air because of slower air movement through the cooling equipment. Consider using an interior fan in conjunction with your window air conditioner to spread the cooled air more effectively through your home without greatly increasing electricity use.
  • Set your air conditioner’s thermostat as high as comfortably possible in the summer. The less difference between the indoor and outdoor temperatures, the lower your overall cooling bill will be. And don’t set your thermostat at a slighter setting than normal when you turn on your air conditioner. It will not cool your home any faster and could result in excessive cooling and, therefore, unnecessary expense.
  • Don’t place lamps or televisions near your air-conditioner’s thermostat. The thermostat senses heat from these appliances, which can cause the air conditioner to run longer than necessary.
Proper maintenance of your air conditioner will also save energy. Be sure to do the following:
  • At the start of each cooling season, inspect the seal between the air conditioner and the window frame to ensure it makes contact with the unit’s metal case. Moisture can damage this seal, allowing cool air to escape from your house.
  • Check your unit’s air filter once a month and clean or replace filters as necessary. Keeping the filter clean can lower your air conditioner’s energy consumption by 5% to 15%.
  • Occasionally pass a stiff wire through the unit’s drain channels. Clogged drain channels prevent a unit from reducing humidity, and the resulting excess moisture may discolor walls or carpet.
  • *In the winter, either cover your room air conditioner or remove and store it.

The humidistat changes with home but reads about 20% low. Can the read out be adjusted to more accurately reflect the actual conditions?


A common problem is dirt. Dirt can affect the thermostat's calibrationand interfere with its operation. For example, if a thermostat is set to heat for 70 degrees is really maintaining a temperature of 73 degrees, the additional energy use can increase your fuel bill by as much as 7 percent.
Google your make and model #manual, the manual will let you knw if it can be calibrated.

Does using dimmers increase power consumption?


No, I don't know from where you got the idea. Dimmers are actually used to reduce power consumption and thereby being energy efficient. Dimmers actually take advantage of the AC current flowing to it and will rapidly switch on and off the current. This happens so fast that you won't recognize power being on and off. This way dimmer switches save power. But to get the real benefit of a dimmer you must change from incandescent lights to CFL. You can actually expect to save about 25-40% of the energy normally used if you dim the bulb to 50% brightness.

RTH2310b thermostat not heating to temperature set, I turn it off and back on, it runs few minutes then shuts off not heating to temp set on thermostat


All thermostats have a "Differential" setting that causes the thermostat to turn off early as an energy saving feature to blow all the hot air out before the furnace fan shuts down. On some stats, there is a switch on the back for setting this and some have a programming choice for setting this time. Others have no setting but normally start the heat about 2 or 3 degrees below the set-point and shut it off 2 degrees above. In this case it would be called a 5 degree differential. Look for these as described and adjust it up 2 degrees if found. Good luck.

thermostat window ac turns unit on and off 8 degrees above se


the unit may be drawing the cool air it just released back into itself,plus the air close to the unit may be a little cooler than the air in the rest of the room.

Oven temperature only gets to within 20-25 degrees of temp. set


next to last page in your manual


Adjusting Oven Temperature
Oven temperature has been factory calibrated and tested. If
oven consistently over or under cooks food, adjust thermostat.
Oven temperature can be increased or decreased 35°F. To
avoid over adjusting oven, move temperature 5°F each time.
1. Push BAKE pad.
2. Press + pad until an oven temperature greater than 500°F
shows in display.
3. Immediately push and hold, approximately 5 seconds,
BAKE button until “00” appears.
4. Press + or - arrow pad to adjust oven temperature.
• To increase oven temperature (for a hotter oven), Press
pad until a positive number appears in display.
• To decrease oven temperature (for a cooler oven),
Press pad until a negative number appears in display.
5. Press OVEN CANCEL pad to save adjustment.
• Setting is saved if power fails or is disconnected.
