H.V.A.C. Parts Direct To the Homeowner!
Before we show you OUR installations
we want to show you some used equipment a homeowner supplied and asked
us to install in a home he just bought!
Below is an evaporator coil that the man just cut loose with a
hacksaw. The copper chips have now entered the refrigerant tubing and will
probably cause a compressor failure very soon. Additionally, the refrigerant was
most likely just released to the atmosphere, a Federal Clean Air Act violation!
That is also a VERY good way of being blinded as Freon is under high pressure (
250 lbs. ).
Below is a close up of the copper chips. We will need to
cut the tubing back with tubing cutters in an effort to remove most of
the chips. We will also have to install filter dryers in both copper
lines to catch trash and any moisture since these lines were left open
during a rain storm. We offer no warranty on this installation!
Below we have cut the smaller line with the tubing
cutter and are cutting the suction
line (
larger line ).
Below is the outdoor unit. As you can see the
refrigerant lines are pointing straight up and unsealed. How much water
has gotten into the system during the rain storm?? We will evacuate the
system to try to boil off any moisture. We hope the dryers will catch
the rest of the moisture!
Note the condenser coil below. It is filthy and needs to
be cleaned with coil detergent and washed out with high pressure.
Below is one of our ac installations.

To the owner (s) of Sheridanhvac.com,
I would like to thank you for a job well done on installing 2 Trane Air
Conditioners, 2 Electronic Air Cleaners, and 1 humidifier on my house on
April of 2002. The job is neatly and cleanly done. I am very pleased with
the professionalism of the technicians who did the installations. I was
always informed of what is going to be done, the status and the progress
during the installation. Besides, your price is very competitive and your
service is among the best. I will certainly recommend your service to my
friends and neighbors.
Thanks again for an excellent work.

Fork lift loading one of our trucks to go to job. The time it takes us get
to the job site often depends how busy the Trane warehouse is.
This customer also wanted (2) Electronic air cleaners and an Aprilaire 600
Humidifier installed. He had (1) furnace in the basement and (1) furnace in the
attic. Pictured is the air cleaner being installed on the basement furnace. Note
that we had to remove the return drop ( vertical duct work in left foreground)
to mount the electronic air cleaner. Later we will have to make an offset in the
return duct work, overhead, to re-mount the vertical return drop and cut a new
hole. Note the electronic air cleaner cells and pre filters over our
technician's right shoulder against the wall. They slide into the air cleaner
housing and should be washed and dried in your dishwasher every 2 months or so
with powdered dishwashing detergent.
Since the furnace had no air conditioning we have to remove the sheet metal
plenum sitting on top of the furnace to make room for the new evaporator coil.
This will involve altering some sheet metal since the evaporator coil is not as
wide as the existing furnace. ( Existing furnace was originally sized too big
for home in the first place since there are (2) furnaces in the 3,000 square
foot home. )
This installation called for (2) 2 1/2 ton condensers using (3) ton evaporator
coils. By over sizing the coils 1/2 ton you gain efficiency, but of course this
costs a bit more up front! The new Variable speed TXV ( Thermal Expansion Valve ) 410A evaporator coil (all
joints are sealed against air leakage) is now installed on top of the furnace.
Note how tall the coil is. ( up to 33" tall ). Many of our competitors
don't over size the coil or install this Variable speed TXV version because it costs
more money,
but you won't get a true 13 S.E.E.R. rating without it and probably won't get
your energy rebate from the utility company either! When getting quotes from
other companies, be sure they are doing the job the same way or YOU will
be the loser in the long run. In some basements you may
not be able to fit this huge coil in because of low ceilings.
Note the copper fittings. (2) refrigerant lines will need to be sweated in to
these fittings and run to the out door condenser. The attic unit already had
it's refrigerant lines and drain lines run into the basement by the home
builder's HVAC people. If they hadn't done this we would have had to run the
refrigerant lines and drains as well as thermostat wiring up the out side of the
home and into the attic. A metal box would have to be made to cover them. If the
basement ceiling was finished this would have meant cutting sheet rock, most
likely. Obviously, this would have ran the job cost WAY up! Before putting up
basement sheet rock, be sure you can add ac later! Call your HVAC Service company
first! Also there will be a 3/4" P.V.C. drain line run to the floor
drain. We will tie the humidifier drain into this same line with a tee.
One of the new Trane 13 S.E.E.R. 2 1/2 ton condensers. Dirt will need to be
imported to level the ground so the equipment pad can be set. Also note the main
electrical panel at the far left of the picture. (2) (230) volt circuit breakers have to be added and we will need to run wiring in weather proof
(sealtite) to each condenser. We will do this by coming out of the bottom of the
panel then going back into the basement and then out to each condenser into a
dis connect box for each condenser.
The condenser has been set on an equipment pad. The refrigerant lines are
sweated into the evaporator coil at the furnace and the condenser we are wiring
up the 230 volt power that we ran from the main electrical panel. Soon we will
"evacuate" the refrigerant lines to remove any non-condensable
(moisture) from the system. Freon and moisture forms acid which will destroy
your system!
Inside the dis connect box.
Wiring, evacuation and dis connect box is complete and hole in home has been
caulked. Now we have to run more sealtite from the box back into the basement
and out of the main electrical panel to house our 230 volt wiring. Note the
grille on the right. This is for combustion air to the basement furnace. (2)
ducts are run from this grille to supply air for proper combustion. Worth
noting here, is a condenser should not block these grilles or be near a dryer
vent as lint will get sucked into the condenser coil.
The (2) condensers are installed and the electrical has been run to the breaker
box. The units have been charged with the new 410A refrigerant. In the
foreground is the dryer vent. Code says the dryer vent can't be within (10) feet
of the combustion air grille. Also the ac units have to be at least (4) feet
from the main electrical meter/panel. Note the yellow E.P.A. sticker on the back
of the unit being blown by the running condenser fan. All equipment comes with
this sticker which displays the S.E.E.R. for the unit. It can't be re moved by
any body but the homeowner. These units are VERY quiet! Trane has units all the way to 18
S.E.E.R. See
our Trane Ratings button on the home page or by clicking on the link back to
Trane Ratings at the bottom of this page for more details. The 13 S.E.E.R. is
what most of our clients seem to be choosing.
Front view of the condensers. These units have a (10) year warranty and we
give (5) years on labor if we install Trane equipment. The pads will be
straightened for aesthetics. The client is going to put gravel around them so
mud doesn't slash up into the coils.
June 2002 13 SEER add on air conditioning and an Aprilaire
Humidifier
To the folks at Sheridan Mechanical,
WOW! Thanks alot!
Not only did you spell out everything up front, answer all of my
questions, display you expertise and work ethic during the installation
of my 13 SEER TRANE 2 1/2 ton AC and new humidifier, but you hunted out
an existing gas leak in my furnace for me.
I can't say enough about your service!
Initially I was impressed with how you explained everything, but you
didn't try to sell me something I didn't want or need. Our AC works like
a champ... my only problem now is daring to go outside on those
sweltering days. Do you guys do lawn-mowing?
Sheridan Mechanical is permanently in our book for trusted mechanical
furnace and AC services!
Sincerely,
RB Edwards
Pictured below is the installation the client gave us the testimonial
above including a 13 S.E.E.R. coil but we have also
installed an Aprilaire 600
humidifier. The humidifier is the large white box on the return drop (
right side of furnace ). Note the ductwork that must be run from the humidifier
to the supply trunk. These humidifiers are called by-pass humidifiers because
the ductwork routes return air through the evaporative pad and back to the
supply trunk. Also note the P.V.C. drain line at the bottom of the humidifier.
This drain line lets the humidifier flush itself of nasty minerals on each
cycle! This is a piece of equipment and not just a hang on, cheap unit. He also
had a gas leak in the furnace which we repaired at no charge as a "thank
you" to him for giving us the job! 
Below is the client's 13 S.E.E.R. A/C unit. This unit carries
a 10 year warranty on all parts from Trane and 5 years labor from us. The
refrigerant is the new 410A.
Below
is a Trane XL90 furnace with an Aprilaire 600 Humidifier that we installed
4-24-03
NOTE: Notice the purple material on the pipes. This is a primer which is applied
to the pipe and fittings first, then P.V.C. glue is applied. A twisting motion
is used to seat them together. They are then held tightly together for about 30
seconds, as a hydraulic action will try to push them apart otherwise. 
Below

is the decorative termination kit available from Trane that dresses up the
installation if so desired.
