Frequently Asked Questions
Q: Is a bigger furnace or
air conditioner better?
A: No it is not. Bigger is not always better in the
HVAC industry. A larger air conditioner uses more
electricity and costs more to purchase, install and
upkeep. A properly sized unit will provide the most
efficient energy use and most comfort in your home.
When buying a home comfort system, selecting the
right size is crucial. For instance, an air
conditioner that is too large will cool your home
quickly but you still may not feel comfortable. It
will satisfy the thermostat before it can remove
sufficient moisture from the air. However, a system
that is too small just cannot get the job done. As
Trane Comfort Specialists, we can help you determine
the right size system for your home comfort needs.

Q: What are the benefits of
a programmable thermostat?
A: A Programmable thermostat is programmed for when
you leave your house and then return home. The
thermostat turns of the furnace during the hours you
are not home so that energy is not used to keep the
house warm while you are at work. The thermostat
will then turn back on 30 minutes before you come
home so your house is at the perfect temperature
when you are home. These thermostats save up to 15%

Q: Why are furnaces and air
conditioners so noisy?
A: They are not noisy if you install new Trane
components in your system. Old units were not built
with the quality materials that are used today.
Trane also installs sound insulators on the
compressor as well as a weather guard top that not
only reduces noise but increases the life of the
unit by not letting debris get into the system.
Q: When I am on vacation
should I turn off my furnace to save energy?
A: Common settings are 85 degrees in the summer if
you have air conditioning and 60 in the winter if
you will be gone for a couple of days. These
settings will keep most plants alive and will keep
pipes from freezing and bursting in the winter.
Q: Do I run any risk by
accepting the lowest bid?
A: YES! If a bid comes in 5-10% lower than other
companies it is because they are using inferior
products, do not do a quality installation or are
leaving something out of their bid. Many companies
will not pay for permits or schedule the inspector
to come to your house. Lewis Air does all the work for you, you just
need to relax and enjoy the comfort and energy
efficiency of your new system
