I just want to thank you for the
outstanding job you did sealing the
duct work on my home. Over the
summer my wife and I noticed a
marked improvement in the volume
of air flowing through our home, and
it was cooler. We can’t wait to see
how much warmer the house will be
this winter (with lower gas bills)

I would be happy to serve as referral
for your future customers. Thank you
again for your help.

Thank you, for finding a solution for
us. Your expertise into Air
Treatment for our CNC machines
working in such a hazardous
environment, we haven't lost a
control board since (do to over
heating and air containments).

You are saving us thousands of
dollars each month. Looking forward
to working with you again in our new
building in Harvard later this year.

My wife and I love our house. Doug
Really knows his art... The building
inspector did not catch things that
Doug had. After you installed
dampers, corrected and sealed the
duct system, the house
temperature is within 1 degree on
all floors (use to be 12 degree
difference).Also there are no more
water stains in the spa room with
the Dehumidifier and Ventilation
system you installed.

               Thank you,

To Whom It May Concern,

I have had the opportunity to work with Doug Krahl and I would recommend him without reservation.
He repaired a leak in our basement ceiling which required removal and replacement of drywall as well as a large air duct. We also had him evaluate
the bedroom above our garage which was cold in the winter.
He provided us with an economical and swift solution to the problem and now the bedroom is warm and more importantly, livable. He always
maintained a professional behavior when in our home. He was timely and courteous. I appreciate and rely on his honest recommendations. This
summer when our air conditioner was not working properly, he provided a quick and easy solution over the phone. I was able to take care of it
myself and have the air conditioner working that day.

I highly recommend Doug to friends and will use his services again in the future. I have provided my contact number to Doug if more information
is needed

Honest and hard working are two
really good words to describe Doug.
He has worked on our furnace at
our home and our auto shop
literally with very little notice and
was there in a min in the dead of
winter. He really cares for his
customer not about the buck he is
making, He is always telling you the
best way to do things to save you
money instead of like most
companies ripping you off. Keep up
the good work American

Doug has an incredible knowledge when it comes to heating and
cooling needs. He stays current with new technology and shares that
with his clients in a very easy to understand way. His pricing is very
fair and you get a great value for the price you pay. Doug is the
definition of going the extra mile for his clients. He has done work
for me and I have had no problems after Doug corrects the problem
he found and my wallet is very appreciative when he is done.
American Temperature Control is the definition of a customer
service based company. Great job Doug!!!!!!

To Whom it May Concern.
When I moved to my present address I contacted Doug and he
came and inspected the complete HVAC system. I felt he did a
very thorough job,so  asked him for a yearly contract to service
and clean both the air conditioner and furnace.

A few days ago Doug came and worked on sealing the air ducts
through out the house, which I believe in the long run will be
beneficial to me from a financial aspect as just with the air
conditioner I see that the cooler air is more evenly distributed and
the air conditioner runs less often and is quieter.

My experience with American Temperature Controls has been
highly satisfactory and  would recommend them to anyone.
