A Guide to Heating and Air
Conditioning
Modern offices and homes have sophisticated
plumbing and mechanical systems to deliver cooling, heating and
ventilation services. Efficiency of room air-conditioner is
measured by SEER, which is BTU/hr output divided by watts of
electricity the unit uses. This gives you the idea of how much
heat you get out from the unit compared to electricity being
put into it. Higher the value of SEER, lesser the electricity
being consumed by air conditioner.
Heating and Air Conditioning
Tips
When the air-conditioner is on, make sure to
shut off the bath, kitchen and ventilating fans after they have
finished their job to increase their efficiency. The most
common substance that is used in residential air-conditioners
is Freon and it is illegal and punishable to vent it to the
open air.
When you want a rapid temperature change, it
is advisable to not set the thermostat higher or lower than
desired temperature. This will not change temperature any
faster but will only make the system work longer.
Cooling efficiency of heat pump is measured
by SEER rating. Heating Seasonal Performance Factor (HSPF)
measures the heating efficiency of heat pump. HSPF of at least
8 and SEER of 12 or higher is considered high efficiency.
While cleaning the heating and air
conditioning system, do not try to clean the condenser coil
without turning off the power.
Hiring A
Heating And Air Conditioning Professional
Most of the homeowners feel that hiring a
professional for the heating and air conditioning is a painful
process. But there are few simple things that must be kept in
mind to so that you get a professional and experienced
contractor without getting cheated in the entire process.
The first and most important thing you must
do to hire heating and air conditioning professional is to
check the qualification and credentials. Legitimate
professionals will happily share this information but if the
person is reluctant to share any background, it is better not
to hire one.
Ask for the certificate of insurance and
make sure that the material used by the contractor is of good
quality. Always be cautious of the heating and air conditioning
contractors who ask for substantial down payments or ask for
the checks made out to someone other than the name of the firm
on invoice or contract.
It is advisable to insist on the waiver of
lien from all the subcontractors who will be supplying labour
and materials for the heating and air conditioning unit. If
your contractor does not pay the subcontractors, they might
enforce a mechanic’s lien against your property preventing you
from selling it.
