I heard a rumor that Daikin took the turbocor compressor out and started manufacturing their own frictionless compressor. Is this true? Just looking for any feedback, and brand new product makes me nervous especially if they are now manufacturing a new compressor as well.

Does anyone know or can direct me to what licensing requirements (in Mass) one needs for units up to say a 20 ton rooftop unit. I am refering to pulling a local permit at Building Dept. other than an EPA certification.

My question of what motivates the far left radical wing of the democratic party of which Obama is the epitomy of led me to this very real theory. Looking at all things done thus far I believe that this is what he's up to.

This is the third failure of the system in the last 3 years. In the third failure, we went 14 days with no hot water in March 2009.

What is particularly disturbing is that 2 of the failures were identical: freon leak in the reversing valve. The third was a fried mother board on the water to water unit.

We installed a Water Furnace Synergy3 in 2006. The table below shows the dates of the failures, my cost out of pocket, and what the “10 year” warrantee did for me, the failure and days out of service.

[table]
Date | My Cost | WF Warantee | Failure | Days out of service
1/2008 | $975.58 | 1 part | reversing valve| 10
3/2009 | $1122.90 | nothing | motherboard | 14
11/2009 | TBD | TBD | reversing valve| 6 n’counting

[/table]

From my experience the problems Water Furnace faces are as follows:

• Part distribution takes way to long. FW Webb does not stock the parts. They – mostly – are shipped from Canada. Waiting is the majority of the down time.

FWIW I went 10 days with out heat in VT in January when the wind chill hit 20 below zero. 14 days with out hot water forced me to drop in an electric hot water heater. And early this week – without heat – temps dropped to 15 degrees.

• The 10 year warrantee is a fairy tale. 3 failures within 3 years have resulted in zero labor coverage and no electrical parts (mother board in my case). One reversing valve was provided; another is expected.

• There is a serious design – or manufacturing - flaw in the reversing valve. 2 identical failures within 2 years is simply unacceptable. My current failure is a leak in the same spot on the same part.

So what lessons do we have for those considering alternative energies:

1. Design backups into you system. I dropped in an electric hot water heater to backup the water to water unit. A wood stove backs up the water to air unit. I am considering electric base board so I am not trapped in the house thru these outages. And a refrigeration contractor backs up my installer (who left the country last year).
2. Double any advertised “pay-back” period. At this pace (3 failures in 3 years) my unit will NEVER pay for itself. Also need to add the costs of installing and operating the required back-up.
3. Don’t rely on the warrantee. It probably won’t be there when you need it.

I’ll be curious to see what labor is covered by WaterFurnance for my current outage … but I am not holding my breath. ]]> Residential Geo Thermal / Water Source Spruce Lake http://HVAC-Talk.com/vbb/showthread.php?t=427112 Thermopride OH6 vs. OL5 http://HVAC-Talk.com/vbb/showthread.php?t=427102&goto=newpost Fri, 20 Nov 2009 18:49:06 GMT I am a homeowner in need of a furnace.

Hi guys! I have seen this video from Waynex2 (the link above) and it just does not make much sense to me. But I'm just a AC student, so may be if you guys look at it and shed some light on it for me?
The pressures shown on the Testo - 149 PSIG suction pressure - isn't that a bit high for "normal condition"? May be on a very hot pull-down?
I would love to here what you guys thing!

This SEIU chief was threatening suit because a boy scout working toward his Eagle Scout rank cleared a walking path in a city park.
From the article:
"We'll be looking into the Cub Scout or Boy Scout who did the trails," Balzano said, and told council that given the layoffs of 39 union members, no one except union members may pick up a hoe or shovel, plant a flower or clear a walking path.

Balzano has since voluntarily resigned. ]]> ARP mrs reb77 http://HVAC-Talk.com/vbb/showthread.php?t=427032 Johnson Metasys experience http://HVAC-Talk.com/vbb/showthread.php?t=427022&goto=newpost Fri, 20 Nov 2009 17:43:03 GMT Looking for Bas technician with strong Johnson Metasys experience .
