’r 1. Choose the right size of system L for your home. In order to achieve + comfortable cooling and dehumidificaâ€" tion, the system must be correctly sized. _ The size of central air conditioning is measured in tons ( 1ton = 12,000 _ _BTU/HR). The unit "ton" originate _ many years ago and is based on the amount of ice required to achieve the required cooling. The following is a rule of thumb guideline for sizing residential systems. But this is only a guideline â€" skyâ€" _ lights, type of insulation, the number _ and size of south facing windows, proâ€" tective shade trees, etc. can significantly affect the size of system required. Your contractor will make the proper recomâ€" mendation during the site inspection. Another factor the contractor must conâ€" sider is whether the duct system and _ furnace fan can handle the air flow needed for central air conditioning. Alterations may be needed. 2. Choose a unit that is quiet. Certain brands are substantially quieter than others and you don‘t want an angry neighbor calling to complain about the noise. Features to look for which conâ€" tribute to quieter operation are: * A twoâ€"speed fan on the outdoor secâ€" tion, with high speed only being used â€" during exceptionally hot periods (e.g. automatic switch over above 90°F/32°C). * A large diameter fan on the outdoor unit to efficiently expel heat at lower rpm‘s (revolutions per minute). * A separate insulated compartment for | the compressor, to reduce compressor noise. Most manufacturers display sound / rating data, measured in BELS on their product brochures. A value of 7.6 BELS has been set as an Ontario perforâ€" mance standard. BEL ratings can be used to compare one brand to another. A rating of 7.2 or lower is exceptionally quiet and above 7.8 is usually unacceptâ€" able to most municipalities. Proper location of the outdoor unit will also have a big effect on noise level. Avoid locating the unit between two houses less than 15 feet apart, in car ports, and alcoves where two brick walls meet at right angles. If the above locations cannot be avoided, a fiveâ€"foot high fence, solid wood or concrete, will reduce the sound transmitted to neighâ€" bors.

A number of features can contribute to long, reliable equipment life: * A factory sealed refrigerant system installed with precharged lines and quick connect fittings. This prevents leakage of refrigerant and system contaâ€" mination by water or dirt which may occur in systems which use soldered fitâ€" tings. * A low ambient cutout switch turns off the compressor when outdoor temperaâ€" tures fall below 55°F/13°C. Central air conditioning can generally not be used at Thanksgiving or Christmas. Accidental startup could significantly damage the equipment. * To ensure that the outdoor unit remains attractive year after year, look for vinyl coated grilles, polyester paint and corrosion resistant screws. 4. Pick a unit that is inexpensive to operate. Almost all central air condiâ€" tioning equipment is relatively inexpenâ€" sive to operate in Ontario. A system needed to cool a 1,500 sq. ft. (139 sq. m) home (twoâ€"ton system) would cost approximately $120 per year at 82 cents per kilowattâ€"hour. The efficiency of central air condiâ€" tioning equipment is compared using a S.EER. value.

A S.E.ER. value of 9 has been set as a minimum Ontario perâ€" formance standard. Some manufacturâ€" ers offer equipment with S.E.ER. valâ€" ues of 10, 11 or higher. An increase in S.EER. value from 9 to 10 represents an increase in efficiency of approxiâ€" mately 11 per cent, and a reduction in operating cost of approximately 11 per cent. For a homeowner in southern Ontario with a twoâ€"ton system, this would represent a saving of $13.20 per year. 5. Choose equipment that is easy to service. If a unit is hard to work with, you‘re eventually going to pay a serâ€" viceman for extra time.

Choose environmentally friendâ€" ly refrigerant. Almost all major manuâ€" facturers now use a refrigerant known as HCFCâ€"22 in their residential sysâ€" tems. It‘s one of the safest available. Also known as Râ€"22, it has very little effect on our ozone layer. The gases which are not environmentally friendly are those refrigerants which have historâ€" ically been used in cars and refrigeraâ€" tors. In addition, the refrigerant used in residential systems is sealed within the air conditioner for the life of the equipâ€" ment. If repair work is required, conâ€" tractors are now trained to collect and recycle the refrigerant. Even environâ€" mentally friendly refrigerants can no longer be released into the atmosphere. With today‘s central air conditioning technology, homeowners can keep cool and be confident knowing that their purâ€" chase is safe for the environment.
