 What
you need to know about air conditioning
In business, having a reliable, cost-efficient
cooling system is not an option, it is a necessity. A commercial
air conditioner is essential to keep your customers comfortable,
employees happy and productive, and equipment cool.
A good cooling system needs to accomplish that while:
- Operating efficiently to keep electricity bills down
- Reliably performing year after year when properly serviced
- Run quietly and be low in maintenance needs
Size
The cooling system must be sized correctly. If it is too small
it will not keep your business cooled sufficiently. And if it is
too large it will cycle (turn on and off) more than necessary,
wasting electricity and potentially straining the compressor.
At Air 1 Heating we determine the optimal system size for your
business by carefully evaluating your cooling requirements. This
can include:
- If you have appliances that generate heat
- Your business’ insulation, the floor
space
- Your window dimensions and exposure
- The local climate and direction your business faces
Efficiency
When deciding between air conditioners with similar features, capacities,
and prices, energy efficiency should be the deciding factor.
Energy efficient units may be higher priced, but cost less to
operate, and can return back the extra initial cost many times
during their lifetime.
The SEER rating (Seasonal Energy Efficiency Rating) is the BTU
(British Thermal Unit) of cooling output during a typical cooling-season
divided by the total electric energy input in watt-hours (W-h)
during the same period. This is expressed by the formula: SEER
= BTU ÷ W-h. The higher the SEER
rating of a unit, the more energy efficient it is. Considerable
energy savings can be obtained from more efficient systems. For
example by upgrading from a SEER 9 to SEER 13 system, the power
consumption is reduced by 30%. This can result in a substantial
annual energy savings depending on your usage rate and the cost
of electricity.
Installation
Having a properly engineered and carefully installed system is
very important. An air conditioner installed improperly, such as
the ducts not properly insulated, will waste energy, even one with
a very high efficiency rating.
Cost
At Air 1 Heating we understand each business environment requires
special attention to cost control while focusing on keeping customers
and employees comfortable. When comparing different installation
estimates on cost consider the following. There are four
costs that make up the total cost of
owning and operating an air conditioning system.
Initial Investment: Without
being properly informed, it is easy to look at the initial cost
on estimates you have been provided and just choose an installer
based on it. However,
what actually needs to be considered is the lifetime cost of
the system, as this deciding factor will cost you more money
in the end.
Operating Cost: The operating cost of the
system is what you will be paying to the utility
company for the next ten or more years. Here are
some of the items that will affect your operating
cost:
- Equipment selected and equipment’s
ratings
- Installation material used and installation procedures
- Installer training and skill level and experience of the
installers
- Supervision of the job
- Condition and sizing of the present
or replaced ductwork
Many business owners for example assume choosing a 13 SEER air
conditioning system results in a 13 SEER system installed. This
is not always the case. It would be fairly easy for a contractor
to install 13 SEER equipment, but deliver a 10 SEER system. Numerous
areas affect the system during installation. Is the refrigerant
copper properly sized? Is the refrigerant copper soldered so it
does not leak? Is the refrigerant charge exactly correct? Is the
air properly filtered? Are there any air leaks in the ductwork?
Is the ductwork properly sized?
Repair and Maintenance Cost: Many of the areas
that affect the operating cost also affect the repair and maintenance
cost. The experience and skill level of the installers play a
large part in the repair and maintenance cost. An example is
an installer that allows dirt and moisture to get into the open
refrigerant piping; this can result later in a failed compressor.
Future Replacement Cost: Any air conditioning system,
regardless of the equipment chosen and how well it is installed,
will eventually need to be replaced. The difference, of course, is
how long the system will operate before needing replacement. For
example, a system properly engineered and carefully installed may
last for 15 years, whereas another system may last only nine years.
