It is hot, the cooling bills are high, and your home or building feels warm. Here are a few easy and inexpensive things you can do to improve cooling and reduce air-conditioning costs (number 9 may surprise you):

  1. Attractive woman covered with sweatOne of the most important things that you can do to keep your home, building, condo, or co-op cool is make sure that windows and skylights are closed when the air-conditioner is running.  You would be surprised to find how many windows are left slightly open in an average building on hot, humid days. Children and cleaning staff may open windows and not close them.
  2. Make sure that the heat is not on in any part of the building. This means the thermostats must all be in cooling mode and/or set to approximately the same temperature. This is a common problem in commercial buildings with multiple heating/cooling zones. Cool air blowing on a heating thermostat may cause the heat to come on.
  3. Be sure that all electric space heaters are shut off. In many offices, staff members run electric space heaters because the office is cold. This causes the cooling to run more, and the space heater to run more. The end result is higher electric bills. Find out why the office space is cold, and fix it.
  4. If you have an outdoor air-conditioning compressor, make sure that it is not blocked by landscaping. Many people plant bushes to hide air-conditioning compressors. As these bushes grow, they block airflow around the compressor. This prevents the compressor from functioning properly. Make sure there is good airflow around all air-conditioning compressors.
  5. Have all outdoor air-conditioning compressors serviced at least once per year. Internal passages become blocked, reducing efficiency. This is especially a problem when landscapers use blowers in the vicinity of the compressors.
  6. Central air-conditioning compressorThe cooler you make a room, the harder it is for the air-conditioning system to dehumidify the air. Depending on the system and temperature, a room may be less comfortable if you lower the temperature too much.
  7. Make sure inside air-conditioning ducts are not blocked by furniture, curtains, etc. The proper operation of an air-conditioning system depends on good airflow throughout the building.
  8. Filters may become clogged, and reduce air-conditioner efficiency. Proper operation of an air-conditioning system requires good airflow. Depending on how much you use the air-conditioner, you may need the change the filter every month. Pets and children going in and out can track in dust and other contaminants that clog filters.
  9. Wear light, comfortable clothing where possible.
  10. Too much filtration can reduce airflow, and result in poor cooling and inefficient operation. Many people buy expensive air-conditioner filters that promise to remove all sorts of contaminants. These filters can reduce the airflow and make the air-conditioning system function poorly. You may be better off using a separate air filtration system.

Listen to all government and weather service advisories. Excessive heat can cause health issues.  If you have health issues, get medical advice as to how the warm weather will affect you. For more information:
