ficient heating and air conditioning you come to expect of your central air con-
ditioning.
Something not entirely new to the market but an added perk are variable
speed air handlers, which pretty much operate the same as the standard but have
an added bonus: a variable-speed blower that can cool (or heat depending on if
you have an added heating coil) in varying speeds throughout the home instead
of an on/off stronger flow that is expected of the standard air handler.
Thermostat
Nowadays there are many advancements, programmable digital thermo-
stats are completely digital versus the old fashioned thermostat with a side
switch dial indicating the temperature. Larger homes and commercial property
can require a variety of thermostats throughout the home or building, so each
temperature can be different in various areas at the same time. For example, if
someone builds a wine room, the room needs to always be between 50-60 de-
grees. There would need to be a specifically programmed thermostat with that
temperature programmed in. Any air conditioning company or air conditioning
contractor can come in and install a digital thermostat specifically for this purpose.
Digital thermostats are easy to program and offer numerous features, all
to provide the very best in heating and air conditioning. And the controversy
about how these programmable thermostats are too difficult to program is a
myth - technology has created them for a reason: all come with manuals and
your air conditioning company can show you how they work.
Some programmable thermostats can be programmed up to seven days in
advance. It can show the time of day and even adjust
to daylight savings time.
You can also purchase remotes that can control the temperature in any room
from your favorite arm chair. Prices can start from $50 and can go up to $200,
depending on your specific needs.
Digital thermostats use either a relay or a semi-conduct device called a
triac that acts as a switch to control the air conditioning unit. Some even come
with touch screens to serve the utmost in convenience. All thermostats contain a
thermometer to control temperatures.
