We had been after changing this old National-US boiler out for years, this year the roll out from the burners started to send carbon monoxide in to the home … enough to cause headaches.
Old National-US boiler
After shutting down the boiler and advising the owners, it was decided to replace the boiler with a new Crown Aruba3 80% boiler. You can see on the picture above the indications from flame rollout on the front of the boiler.
New Crown Aruba3 80% boiler
We positioned the new Crown Aruba3 80% boiler to face 90 degrees from its original position. This will give the service technician easier access to both the boiler interior and exterior controls for maintenance and repairs if needed.

This 90% Whirpool furnace has seen its last days. It has actually been dead for some time now, the owner finally decided to install a new American Standard 95% Standard furnace.
Old Whirlpool furnace
This Whirpool furnace had an option of 2 different BTU inputs, something I have never seen before. But being a 90% furnace its was very easy to swap over to an 95% American Standard.
New American standard 95% furnace
The American Standard 95% 2 stage variable furnace is by far my favorite furnace to install. I know exactly what to expect from this furnace and I have had zero factory issues with this model. Outside of making a few sheet metal transitions this American Standard standard 95% furnace was very easy to install as well. And like the 2 stage variable … no factory issues.

This customer of mine had a Trane 90% furnace that was zoned. 1 Zone for up stairs and 1 for down stairs. It appears the system was designed correctly, but after digging deeper into the system we found it was not installed correctly. The poor installation contributed to the failure of the furnace.
After several conversations with my customer we had decided to move the furnace location and remove the zoning all together. Each floor would have its own American Standard 95% 2 stage variable speed furnace and duct system. In my opinion this should have been done to begin with.
Trane 90% furnace 2nd
The existing furnaces secondary heat exchanger was getting clogged and also was showing signs of external condensation on the heat exchanger. During the installation I found out why.
Existing Return System.
In the picture above your actually seeing into the return air system, its not uncommon to use chases or voids for return ducting. It is uncommon but not rare though for the return air to be blocked by insulation. During construction an insulator had no idea he was blocking the return by insulating the interior wall. By doing so all of the return air was being pulled from outside, during the winter this cold air would cause condensation on the heat exchangers and cause outrages heating bills.
New Furnace Location.
The new location had to be dug down to allow for the 2 new American Standard 95% furnaces. Above you see the area before we started.
Future Location
It was decided to add a block wall to help clean up the area and hold the soil back.
New American Standard furnaces in place
As you can see the new American Standard furnaces where placed on cladlite pads, ducting was divided from up stairs and down stairs then connected to the appropriate furnace. Honeywell 4″ pleated filters where used for filtering.

Another 30 year old furnace that should have been replaced 10 years ago, it took a home inspector and a new home owner to get this monster replaced.
Old 80% Ruud furnace
As you can see the Ruud furnace was tucked away in a closet, the combustion air was pulled through louver doors from with in the home. This is very typical in older homes.
The new American Standard 95% 2 stage variable speed furnace
The American Standard 95% 2 stage variable speed furnace slipped right into place. Because the home owner wanted a better filter system (Honeywell 4″ filter bank) I had to make a slight transition to adapt to the existing supply ducting.
Sun-Pure UV light
A new Sun-Pure photo catalytic ultraviolet disinfection light was added because one of the family members was suffering from allergies. Sun-Pure in my opinion and my customers is a very good product that really does what they say it does.
By running the optional 2nd PVC pipe out (combustion air) we eliminated the need for the louver door, so the customer if need be can replace the louver door with a solid door.

This Rheem 90% furnace is 30 plus years old and very tired, my customer knows its a money pit and wants an upgrade.
30 year old Rheem furnace
Even though you can not see the difference in the size the older furnace was 3″ wider and 6″ shorter, in my opinion to utilize the existing electronic air cleaner better they should have tried to matched up to it. Instead they overhung the air cleaner. Fortunately the American Standard 95% variable 2 stage matched up perfectly. I still had to make a few transitions to adapt to the existing supply air.

We have been out on several occasions for various reasons for this customer, one of which was their Navien Cr-210a installed by another company had issues. One of those issues was the venting.
Navien 98% tankless heater
As you can see above there was way to much thought going into installing the venting for the Navien. Too many elbows can cause excessive restriction in the venting, resulting in lockouts as well as overheating.
Corrected Navien venting
After a few changes in the venting I was able to eliminate 4 90 degree elbows. Now the Navien can breath a little easier.

A few times a year I get asked to gas pipe in a generator, in this case it was to a Kolher 30kw.
Kohler Generator
Because a 30kw generator takes more gas than what a normal household gas line can carry the customer had the gas company install a high pressure gas meter. We then installed a pressure regulator at the generator location. This way we had plenty of fuel for the larger generator.
New regulator and gauge
Above you see the new gas line with a new regulator installed. You will also notice we added a pressure gauge and bleeder after the regulator. My customer wanted to be able to monitor the pressure and bleed of any air or gas if need be.

Many years ago I install tons of Lennox Pulse furnaces, and I absolutely hated them. Not only were extremely heavy, they were extremely loud. The very first thing out of the customers mouth was “wow this furnace is noisy”.
Lennox Pulse Furnace
The nice thing about Lennox pulse furnaces is replacing them. The American Standard 95% Variable 2-Stage is a little shorter making it easier to retro fit in … and the American Standard is VERY quiet compared to the Lennox.
New 95% 2 Stage Variable American Standard
As you can tell the American Standard 95% 2 stage variable fit right into place with a few minor duct changes. Because our customer was complaining about a musty smell in their home as well as concerns over filtration we installed a F300 Honeywell Electronic Air Cleaner as well as a Sun-Pure UV light system. I also added a low wall return duct to help pull cold air off the floor.

If you have a hydronic heating system, and you have an older Wirsbo manifold system I would think about looking at the condition of that system. In particular I would be looking at the gaskets, these have rubber or ceramic type gaskets, these gaskets need to inspected and or replaced every 10 years(in my opinion).
Wirsbo Manifold
Here you see a 5 zone Wirsbo manifold(s), 1 manifold for supply and 1 for return. 3 gaskets are needed in each manifold.
Opened Wirsbo Manifold
Above you can see where we opened up the manifold for inspection, making sure to have drained the water from the system below the manifolds before starting.
Damaged Gaskets
In this manifold we found several damaged gaskets, we elected to replace all 6 gaskets in 3 different locations through out the home.
