Air Conditioning Tips

By Frank G. Ross

Residents of Southern Utah are aware that the summers can get pretty hot.  The soaring temperatures make having some kind of cooling system in place more than a luxury.  Regardless of the type of system, taking care of it will likely extend its life and keep you cool for longer.  There are plenty of things you should be doing that can save you money in the long run including regular maintenance. Here are some suggestions for Central Air Conditioning systems:

Energy Saving Tips

·         Don't locate your air conditioner in direct sunlight-particularly on the south side of your home where it will be forced to work much harder to do its job.

·         Reduce your cooling costs by increasing the thermostat setting by a degree or two. Try setting your thermostat around 76 degrees. Use a programmable thermostat so you can adjust the temperature setting when you're not at home.

·         When you want to achieve rapid temperature change for comfort, don't set the thermostat higher or lower than the desired temperature. That doesn't cool or heat a home any faster-it just makes the system work longer and may ice up the compressor.

·         The use of window air conditioners can be more cost effective than a central cooling system as you only cool down the areas required.

·         Close off the kitchen, bath and other ventilating fans as soon as they've done their job. In just one hour, these exhaust fans can blow away a houseful of costly, cooled air.

·         Keep doors and windows shut whenever cooling. If fresh outdoor air is required, turn off the air conditioning first or use an air exchanger system.

·         Clean or replace the filter at least once a month. Let your electric bill be your regular reminder to clean or change the filter.

·         Turn the power supply to the cooling system off during the winter. Remember to wait 24 hours after breaker is turned back on prior to next season's start-up.

·         Good insulation in your home can more than pay for itself in just a few years, in money saved on air-conditioning and heating operation.

·         Dirty filters cause unnecessary strain and can lead to equipment breakdowns. Air-conditioning servicemen say about half of their trouble calls are traced to dirty filters. I suggest changing or cleaning your filters at least once a month.

·         If your unit is 10 years old or more consider a new, properly sized, high efficiency system.

·         Check your duct system for air leaks and for adequate insulation.

·         Attic temperatures can soar in the summer so good attic ventilation will lower the temperature and reduce cooling requirements inside your home. Be sure not to block off the attic vents by accident or on purpose. The vents are made to help your attic breathe.

·         Seal leaks around doors, windows, electrical receptacles & switches, roof and wall protrusions.

·         You can save money by shading the glass with awnings, solar screens or shutters. Trees and shrubs that shade your home also help to reduce the air-conditioning workload.  Venetian blinds or drapes are helpful as well.

·         Close up your firebox area and fireplace damper during the summer (when not in use) to help prevent cool air from going up the chimney.

If you have questions about your present system or how to improve it, seek further professional advice from an expert such as a qualified and licensed air conditioning contractor.

Maintenance Tips

Regardless of the type or age of your equipment, it is a good idea to make sure that it is operating properly before and during use.

·         Whether you have a window unit, central air unit, or a heat pump, you can do many of the maintenance tasks. These include cleaning coils, replacing filters, lubricating motors, and checking belts.

·         Indoor unit coils should be cleaned periodically with a vacuum cleaner or brush. The outdoor coils should be kept free of grass, leaves, shrubbery and other obstructions.

·         If your air conditioning equipment needs servicing, hire a professional. They can perform the more difficult tasks such as pressure testing, recharging with refrigerant, checking thermostats and sensors, and repairing or replacing electrical and mechanical components.

·         Check your owner's manuals for information about proper start-up and operation of their equipment. Also, make sure that registers and vents are not restricted or blocked by furniture, carpets, rugs or curtains.
