Cost Saving Ideas
When it comes to energy, less is more …and there are things a home owner may do to control air conditioning energy costs.
In a typical Phoenix area residence, heating and cooling energy consumption accounts for 50% of the annual power bill. Power costs are a dependant on: Utility rates; System design; System installation; System operation; and System maintenance.
Utility rates are usually the sum of "demand" charges (instantaneous maximum energy requirement) and "energy" charges (kilowatts of power). Most utility companies have "time of use" plans which relate both demand and energy charges to the time at which it is used. Overall power company demand for energy is lower at nights and on weekends when commercial customers are closed. .. this leaves the utility with excess generating and transmission capacity which it can afford to sell at reduced rates. (Sometimes as much as 50% less.)
Utilities have several rate plans for residential customers, so first check with your utility and determine the most advantageous rate plan for your normal living schedules.
Then, plan your activities to take advantage of the rate schedule you select.
By doing laundry doing "off-peak" hours, you can reduce the rate you pay for about 8% of your energy...If you heat water electrically, off-peak laundry reduces the cost on 27% of your energy. If you have a pool, operating the pump during "off-peak" hours reduces the rate on another 6% of your energy.
Sometimes, a single air conditioning system serves both upper and lower levels of a home. Since warm air rises, year 'round the upper levels may always be warmer than the lower levels. Solutions to this is checking air balance (see below), or possibly the installation of ceiling fans to enhance air circulation and level off the temperatures throughout the home.
It is not unusual to find easily correctable defects in the manner in which air conditioning systems are installed. A few to look for include:
Improper Air Balance
The ideal situation is to re-circulate air distribution to each area in proportion to the cooling/heating load of the space. Many contractors improperly balance a system, leading to over conditioning some spaces while under conditioning others. The result is uncomfortable conditions in one area, requiring extra hours of system operation in an attempt to obtain the desired space temperatures.
The cure is to rebalance air flows throughout the home. (In two story homes operating on a single system, this may be difficult to accomplish without some form of zone control.)
Studies by California power companies have found that 20% or more of the energy used to heat and cool a typical residence is lost through duct leakage. Ducts improperly installed or sealed waste energy. The simple solution is to have your contractor perform a duct leak test, and if leakage appears to be above an acceptable minimum, correct the deficiency.
The thermostat installed in the majority of homes may be of the non-programmable variety which many owners use as an "on-off" switch.
Replacing a standard thermostat with a programmable stat can pay for the replacement in relatively short time. Program the stat to provide for temperature set-back if the space is not occupied, and AC unit operating hours are reduced.
Improper system maintenance can significantly contribute to energy costs. Systems overcharged or undercharged, and dirty filters, evaporators, or condensers all contribute to excess energy costs and unnecessary equipment wear. The following graph reproduced from the EPA Energy Star website illustrates the importance of air conditioning system tune up and maintenance.
Per the above chart, it would not be unreasonable to bet that the average home may have an efficiency of 15% due to inadequate maintenance. If that home were 1800 square feet in area equipped with a 4 ton SEER 12 unit, monthly cooling heating bills would be about $100.00.
Were it possible to save $15.00 per month, your maintenance plan would pay for itself in energy savings alone while providing increased comfort.
We have had significant experience with resucing residential energy cooling costs, and welcome the oppertunity to discuss your energy concerns.
