@ July 5, 2013 8:41 AM in reviews of new mirco channel coilsAir Temp units last year. They have gone to both condenser and evaporators of aluminum, so far so good.
My main unit is ARCO AIRE (ICP) and they have gone to just an aluminum evaporator. They even have a 20 minute video on the counter at my supplier detailing why they have done this. Of course it is all about performance, not a word about cost BUT they do give a 10 year no hassle warranty . With that kind of warranty they are willing to bet it will hold up. We will see. Putting one in today. Maybe it will be a good thing because I have been hearing all types of problems with copper coils lately. All different makes.

@ July 4, 2013 12:31 PM in What type of dehumidification systemsI dont know. I would imagine the type system that is circulated through the floor and walls, similar to radiant heat.

@ June 26, 2013 7:19 PM in 6" Boiler Exhaust w/ 5" chimney liner. how bad is this?Is there a difference in btu capacity between gas and oil?
@ June 24, 2013 10:08 PM in 6" Boiler Exhaust w/ 5" chimney liner. how bad is this?According to that chart if I were to install a Buderus 115 ws, I would need to increase the 5 inch factory collar to 6 inch.
Obviously Buderus feels comfortable firing 1.10 gph into a 5 inch outlet.
@ June 23, 2013 10:13 PM in 6" Boiler Exhaust w/ 5" chimney liner. how bad is this?that differentiates between the two. Could you please post your chart?
@ June 23, 2013 7:36 PM in 6" Boiler Exhaust w/ 5" chimney liner. how bad is this?according to this chart.
@ June 23, 2013 7:10 PM in 6" Boiler Exhaust w/ 5" chimney liner. how bad is this?Liner capacity is based on vertical length, diameter and horizontal distance . Also based on natural or induced draft. It is best to install the proper size liner and not just use what the manufacturer welded to the top of the boiler.
You will notice manufacturers will use the same size flue outlet on several of the same series boilers before jumping to the next size.
So I am not saying yours is correct but it very well could be.
Give us the length of the chimney and the length of the horizontal flue and the input of the boiler and we will tell you if the 5 inch is large enough.

It keeps me busy all summer long.
I use to handle Fujitsu but what I have found is that after several years the Fujitsu plastic really yellows.
So as of the last few years I have been installing Comfort star and Samsung.
The Comfort stars work really well and internally are identical to Samsung but they only come in white.
The Samsung Vivace is mirror black just like the TV.
I find you don't need gauges since the txv is inside the condenser unit. That is why you insulate both lines. What you do need is a good automatic scale and a small reclaimer.
I also just purchased a UNIWELD 2 stage vac pump that weighs 9 pounds. I also keep a 300 ft tank of nitrogen in the shop and refill my 10 ft tank after each job. No sense in dragging around a 35 lb vac pump and a large tank of nitrogen for a mini split.
You will be drilling a lot of 3 inch holes through a lot of different materials, so be prepared with an assortment of bits.
I have also found in homes with pets and some without that the squirrel cage blower will have to be cleaned after a couple of years. After watching guys struggle with a bottle brush or making a mess on the wall I have found it is best to remove the blower wheel and use a garden hose to clean it. It is not that complicated but I would recommend taking your first one apart on a bench in your shop until you become familiar with it. Long magnetic screwdrivers really help as does a small magnetic dish.
Also after taking them apart you will find they all roll off the same Chinese assembly line using the same parts.
You will also need a few adapters( 5/16 OR 1/2x20 UNF) core remover and a 5/16 low loss x 1/4 flare adp. Also because there is no low and high side you will need a dye injector and you will need another 5/16 low loss x 1/4 adapter for that.
I love installing ductless and my customers love it even more.

@ June 13, 2013 6:30 PM in How the Europeans do it?very popular in countries like North Kore and China. What they do to deserters is arrest their family.

@ June 12, 2013 9:34 PM in How the Europeans do it?I don't know about that Mark. I don't feel college degrees are as important in our field as is natural intelligence.
In many fields especially ones where facts and figures need to be repeated to the point of nausea , a college degree can be beneficial. Probably a photographic memory even better. But in our situation where everyday brings new places with new situations the ability for critical thinking is more desirable.
Personally I find the best apprentices(not always) have a n IQ of 120 or better( no higher than 140 or they detach) a mechanical aptitude of 95% or better with high scores in spacial relations.
This criteria is much more desirable in our field than a run of the mill college degree.
So why shouldn't someone with high natural intelligence make more money than a simple college degree? Many MENSA members are high school dropouts.
@ May 31, 2013 4:19 PM in How critical is this new 410a flareI guess Ill let go of the hundred bucks.

I agree it is an excellent tool, I just want to know what is the difference between this and the new one. Cant seem to get a clear answer on this.
@ May 29, 2013 5:02 PM in How critical is this new 410a flareI have an older yellow jacket deluxe flare tool that I have been using for many years.
I can honestly say I have never had a leak in one of my flares. But I keep hearing that you must use the new deluxe flaring tool on the new mini splits.
I have even taken my older unit to the supplier and made a flare with mine and then with their newer unit. I am really hard pressed to see a difference in the two.
What is the difference between the Two and how critical is this? Who here has already purchased the new tool and can really attest to it working better?

Start thinking Water Conditioning systems and Graphene base RO systems.
