Same reason a person climbs a mountain, because it's there.:)

I was charging a small r22 system outside after a repair. I had a habit of purging the gas and sniffing where it came out to see when...

Just for fun change the meter's batteries then recheck.

No not resi. I'm considering DDC and related controls as well as more complexity in systems. Sure resi has some electronics involved but in a simple way. Like a board or interconnected electronics....

Hvac has moved over time into more & more electronics. A lot of hvac techs and electricians get lost in electronics.

A fix for pin hole leaking copper water lines is injecting a sealer into the lines.
Other than not having the mess re-plumbing would cause it's about the same $$ but a lot less time.

Some guys close the vents once the air has worked it's way out of the system to prevent water logging the tank. I would of liked to know this trick early on systems that water logged a lot.

I've never seen type K spec. anywhere except installs where the engineer was uping the price. They get a % of the job. If type K is spec. it's often overlooked as excessive.
Type L was code in Ill....

Duct leakage is usually part of a T&B report. It's based on measured flow at the unit and adding up the terminals for a % of flow. Usually 10% was accepted but I think that might be high in some...

Thanks dschiffer.

A snag one tech didn't see coming was he did a side job for a neighbor. He moved from the neighborhood.

Does it make any sense to create your own CPI?
When looking at the Consumer Price Index it has many areas that don't affect everyone.

Before you call someone stupid, consider that they just might know something you don't.
Especially about investments.

I noticed the yellow ones have a kind of bitter component.
The blue ones, not so much.

I've seen some of these solutions that have their own problems.
You exhaust the humid air that adds evaporation resulting in cooling the hot tub. The tub is heated resulting in more evaporation. An...

I've always told the guys if you don't know why a compressor failed, your chances of having another are high.
I had a check list that had a number of things to check on a replacement. Most often a...

I remember a couple guys that missed diagnosed a compressor. In warranty. Not exactly ethical but Like you they ran it pen to the atmosphere. For hours. Finally overheated enough to ground.
These...

A question? If humidity is condensing on the ceiling, the ceiling is below dew point.

Is insulation missing in the ceiling or not installed as designed? Is cold air blowing on the ceiling.

Some companies are out of bounds with some requirements.
The worse was a national retailer. They wanted to see all parts invoice and would only allow a 10% over cost.

I have a book with tables of the effect of torque values using lubricants. A lubed bolt torque isn't the same as dry. Even a cad plating makes a difference.

I looked this question up in Carlyle service guide. 06D&06E's. P25, "Install new valve plate gasket. Oiling gaskets for re-assemble is not recommended. Using proper hold down torque will prevent any...

Just curious as to why the Philippines? I have understood that sourcing some products and crafts can be difficult in some countries.

I believe your correct.
A problem of sometimes of listening to others. Like "This is how we've always done it".

A head gasket on a refer compressor don't compare to the forces, for instance, on an internal combustion engine.
Compressor oil has been the recommended application as far as I remember. I...

The electric supplier should be able to tell if their power is dirty and might benefit from a reactor

The Pluto channel also has a military section with lots of original footage.

Starting a business has a question of where are the customers going to come from.
Some have suggested they pirate from their former employer. The worst choice IMO. They will

I wonder why this is. In commercial applications I see reheat at times. Is this a code in NY?
Is reheat allowed in commercial?

If you do flush try to cook it off as soon as possible so corrosion doesn't get a head start.
I know you probably knew that.

Are you looking for commercial or resi load soft ware?

Why would you want an outlet you can't adjust. You might as well just have a hole.

I believe alignment is more important then tension if tension is near correct.
Seems alignment will cause more related problems.
I know most don't use a tensioner. It's a good idea as most are...

The military isn't for everyone. Some take to discipline while others don't.
There are some that break during basic. That's the whole idea. Break where no one is affected.
Others thrive.

Even if the flares were somewhat different, the fitting would compress the flare and make any change.
I also liked the Rigid. The eccentric movement of the anvil (?) strops the flare.

You'll most likely get a better pay back if you insulate the floor and ducts.
Insulation doesn't draw power and will pay back from the start. While the mini is still costing you money.
