Yes there was a mistake, The guy at the parts counter got something wrong.
His manager got the right price and it was reasonable. Im glad I posted because when he told me that I asked him to double...
We condemned the heat exchanger in a 13 yr old 10 ton Voyager. I called Trane parts to get a price to send a quote to our customer, They want over
$10,000 for it. I cant believe what Im hearing....
I would use the process of elimination. Maybe its the in the economiser and
trips on cool mornings. Have you checked economiser operation? I have found
shorts in the bundle of wire running through...
I would use the Lennox oem replacment parts to save time and to be sure its repaired to factory specification. But you will likley need the heat package M# if you call Lennox
Is it Columbus Ohio? Col. Temperature Control on 5th ave should be able to get you the Viconics control you need. You can have it next day shipped
I dont see anything wrong with the idea of a splt system with 6 zones. If the
load calc. calls for 2.5 tons so be it. A good zone system installed properly
will serve well in this application. It...
I would measure the cfm at supply defusers to see what is being delivered.
I would also traverse the supply duct to see what the air handler is actually
putting out. I would assure the filters and...
What are the problems your having. Is the supply air staying around 55 ?
I assume you need to dehumidify the rooms. Is there adequate ducted returns for these rooms? I would consider a stand alone...
Thanks for the replies guys. I spent some more time investigating this. Using
a sheet of paper from my note pad and smoke I determined the exact place
the water is getting in. The door gaskets are...
Water leaking indoors was the complaint. These are 15 and 20 ton L Series.
I determined the water is being drawn into the blower compartment (durring
heavy rain) around the door. These units are...
Yes I have! I have replaced at least 6 all within the 1 yr warranty. Its a
stupid engineering mistake that will cost building owners and tennants alot
of money. And I get to be the guy in front...
I thought gas would not flow unless there is a negitive pressure at the outlet
of the valve. That is why they dont need a saftey switch to prove the comb-
ustion fan is running. If its not...
I would use one of the AH's xfmer to power the stat and a relay in each of the other 3 pieces of equip. Each cond. and AH would use thier own xfmer
Much simpler than trying to paralell xfmers which...
You might be able to just install eggcrate grills in the drop ceiling to solve the return air problem. the area above the ceiling serves as the return air plenum.
No sheet metal needed. Many of the...
Yes a/c is correct but what does that have to do with
the heat not working. Did you try heat op. in test mode?
By the stephen, where the expansion tank is connected
to the system is the point of no pressure change. The pump cannot change the pressue at this point. So it is desirable
to pump away from the...
What size is the unit?? That 12x27 is actually 10x25
because of the isulation liner. That looks like a 7.5 ton
or maybe 10.My ductulator is in the truck but Im pretty
sure 10x25 wont even handle...
Caulk where the cap meets the liner? That makes sense
I got up there and chipped away all the loose stuff which
was alot more than I thought. I noticed all the damage was
around the flue cap. So i think is is due to the moisture
in the heat...
Yes there is a ceramic liner. The chimney is for a gas
fire place only. I found a place that has a polymer
compound for repairing the cap. I thought I would reskim
the entire cap and then use a...
I noticed several cracked bricks on the top 3 ft of my
chimney and a couple brick have lost the entire outer face.
A roofer told me that water is penetrating the brick & morter and freezing causing...
We're a non union co. and we provide all of our own tools
except torch.,vac. pump,recovery,pwer tools,shop vac &
hoses. They also cover repairs like new gauge or hoses etc
I believe I have at...
On some Carrier package unit models there is a stainer screen on the outlet of the condenser coil. I would check
for a temp. drop there and throughout the circuit before
concluding the metering...
That makes sense to me. But is there a special flange with one side metal and one pvc? Seems that would work good.
Why should it be Schedule 80? Im guessing it can tollerate
more vibration and...
Its a problem that occurs durring econo. operation. Not when ventilating(min position). It seems we've lost Fonzy
anyway. I would agree excessive fresh air
would add to the problem and it should...
