Why Every Homeowner Should Ask Their HVAC Tech This One Question

Recently, I sat in on a meeting with Roger, who serves as the Chairman (and formerly President) of a large Oakville-based heating and cooling company ( The conversation turned at one point to what we call SAQs – also known as should-ask questions.

Unlike FAQs, an SAQ is a question most clients and customers would benefit from asking, but don’t. Every industry has its SAQs, and they can make for excellent informative blog and social media content.

As Roger tells it, one of the big points homeowners should be asking him about (but don’t) is this: what kind of training do your technicians receive? 

Or, when speaking to one of his technicians, when was the last time you sat in a classroom?

HVAC techs in Ontario are licensed. However, as Roger points out, you only need to get licensed once – there’s no follow-up exam for renewal and no continuing education requirements.

Problem is, heating and cooling technology changes fast.

In the last ten years alone, we’ve seen:

  • Evolution of programmable thermostats to touchscreen smart thermostats;
  • Widespread proliferation of Bluetooth- and Wi-Fi-enabled smart home technology that can be controlled with a smartphone;
  • Integration of heating and cooling equipment with other smart home technology;
  • Greater adoption of tankless/demand water heaters in detached homes;
  • Energy-efficient furnaces with variable-speed Electronically Commuted Motors (ECM);
  • Push for high-efficiency heat pumps through rebates in Ontario; and
  • Ongoing changes to ENERGY-STAR standards as heating and cooling technology continues to become more efficient.

Without any ongoing education or training, would a technician who got licensed in 2008 know how to install, troubleshoot or repair a smart thermostat?

Would a technician who has only worked on residential properties know how to tune-up a tankless water heater?

That’s why homeowners should be asking their HVAC technician (and the company that employs them) about continuing education.

It’s also why Roger requires his technicians to participate in training sessions, whether they’ve been licensed for ten days, ten months or ten years.

Being a heating, ventilation and air conditioning tech isn’t only about helping people maximize comfort and efficiency – it’s also about ensuring homes are safe. It pays to ensure the person you’re relying on to fix a problem or conduct preventative maintenance engages enhances and refreshes their knowledge on a regular basis.


The Archive Feature In Facebook Stories

Instagram embraced Snapchat-like stories first, which were then taken off on Facebook. Content mode went ahead of Stories on Instagram and that was again taken off on Facebook later. We obviously see the pattern. Now, after Instagram got the component to file stories, the same has now been made accessible for Facebook clients as well.

Essentially, if you utilize Facebook Stories, you will now observe the File choice on the upper right, simply over the line of stories. This component gives you a chance to share a story without really downloading it to your phone. In this way, on the off chance that you set up a story and you need it to stay with you for longer than 24 hours, you can document it. You can re-utilize it in the future if you need, or you could simply keep it for memory for whatever length of time that you like.

Your files can’t be seen by anybody except you. The organizer sets aside on Facebook and won’t consume up any room in your gadget. If there is any story you chronicle, which coincidentally, could be both video or picture, you will likewise have the alternative option to erase it on the off chance that you ever wish to.

Also, there is no restriction to what extent you can keep a picture file. Simply make sure to document a post before it terminates (24 hours). Facebook had reported this element back in May. Alongside it, the stage additionally reported voice posts in Facebook Stories, which will give you a chance to impart pictures to sound clasps put to finish everything. However, this element is pointed basically at Facebook Lite users.

Additionally, Facebook said it will discharge a component, which will enable clients to spare the photographs and recordings they catch for later on Facebook, rather than sparing it on the gadget. Similar to a feed draft on Instagram.

Below are the 4 steps on how to save a post from your stories archive to your device.

Stage 1: On your Facebook News channel, tap “Your Archive” in the upper right corner of the screen.

Stage 2: Tap on the post you wish to spare.

Stage 3: Tap the three specks in the upper right corner of the screen.

Stage 4: Tap “Spare [Post]” at the base of the screen to spare the post to your gadget.


6 Magnetron Sputtering Techniques

Magnetron sputtering is a physical vapor deposition (PVD) technology that uses magnetrons to confine electrons to a specific deposition path. This article provides a brief overview of sputtering techniques using magnetron systems and magnetron sputtering information.

1. DC Power Sputtering

Sputtering using DC power is effective for depositing conductive target metals, conductive oxides, or certain magnetic materials. It is not suitable for non-conductive materials.

2. Reactive Gas Sputtering

Also known as reactive DC sputter deposition, this technique enables higher deposition rates and precise stoichiometry for metallic targets. The target is sputtered in an environment of partial pressure of reactive gas. As the pressure increases, the target’s surface transitions from a metallic to thin oxide or nitride layer, and charge accumulates on the surface until it dissipates as an arc. The molecules that evaporate during the arc are deposited onto the substrate.

3. Pulsed DC Sputtering

Pulsed DC power is used in magnetron sputtering processes that are prone to arcing. A negative bias is applied, with a reverse bias to remove charge accumulation between pulses. Pulsed sputtering minimizes arcing during a reactive process, reducing the chance of unwanted film properties and inferior performance.


High power impulse magnetron sputtering, better known as HIPIMS, is a technique that uses short, intense pulses of DC power to form a highly dense plasma near the target to boost the sputtering rate. The pulses are delivered with a low duty cycle to minimize excess heat and maintain a manageable average operating power.

5. Facing Target Sputtering

Facing target sputtering, or low-damage sputtering, uses two magnetron sources placed opposite to one another at right angles to the substrate. It is intended to minimize the risk of damage to a soft or organic substrate. This configuration is designed to confine plasma between the sources in order to reduce electron density which reaches the substrate.

6. Radio Frequency Magnetron Sputtering

Certain materials with high DC impedance cannot be sputtered using DC power. For these applications, it is possible to deliver power using radio frequencies and an automatic impedance matching network to maintain a plasma. Radio frequency sputtering is used to deposit materials like oxides, nitrides, and ceramics.


Hints That You Need To Let Go Of Your Old PC/Laptop

We’ve all experienced or known somebody who has finally replaced or upgraded their old and irritating PC/laptop with a more slightly advanced and brand new one, only to discover after a month or two later that there is a strikingly better one that got discounted. We all agree on this part, that no one likes to make a major buy and then get stuck with a not so old model for last year. Also, the bill from your credit card is pretty harder to swallow when regardless you’re paying for it that is not even marked down any longer. So when do you determine the perfect time to obtain a new or upgrade your PC/Laptop?

Here are hints that you need to let go of your old PC/Laptop.

  • It’s running slower

Slowness can be hard to characterize, however, you’ll know it when you see it: Your PC/Laptop is taking too long to boot up, it comes to a standstill when you have twelve tabs open in your program, and you can type a full sentence before a solitary word shows up on screen.

If this happened then you should perform all the things below:

  1. Know How Much Free Storage Is Left
  2. Delete All Junk Files
  3. Defrag Your Hard Drive
  4. Check for Malware
  5. Clean the PC/Laptop
  6. Seek help for a professional technician to fix it

Yet if there is no change in the performance of your PC or laptop, it is considered as a sign that your unit needs a replacement.  Here are some more hints.

  • Having low storage

On the off chance that your hard drive is being crushed for space and you open the framework screen on your PC and see that the CPU utilization is routinely hitting at least 80%, at that point it’s an indication that you’re getting to the breaking point of what your equipment can do. You can get yourself more time by including an outside hard. In any case, when in doubt, once you need to begin dealing with this, an update won’t be far away.

  • Length of your pc/laptop service

The longevity of a laptop, for example, is 4 years depending on the use of the owner and the model. Old models have old OS, lack of other features and more. The older the unit is, the more prone for the deterioration of the mechanics. Try to access your laptop or pc then decide if it is the right time.


Why Don’t Air Domes Get Blown Away By the Wind?

Ever wondered why those big, inflatable air domes don’t get carried off by the wind? They certainly look like they should — after all, they’re made of fabric and full of hot air. One would expect a structure with the shape and squishy-ness of a giant marshmallow to be vulnerable to the whims of Mother Nature. But most of the time, air domes manage to stay in place even through the nastiest of wind storms.

Turns out there’s more to an air dome than a puff of air, according to a dome-maker called the Farley Group (visit to see their work).

How Air Domes Stay Grounded

It’s no small feat to keep an air dome down, especially the bigger sports domes that are hundreds of feet long by several stories tall. The upward force of the air inside is massive. So what keeps it grounded?

A concrete grade beam that runs the circumference of the dome provides a solid foundation on which the dome sits. Think of it like the foundation of a house, but for a dome. There’s also an aluminum profile, which bridges the gap between the fabric and the grade beam and acts as an anchor.

The dome material is securely fastened to the grade beam, which is inserted into the foundation before the concrete cures and is thus totally anchored down to the ground. It’s only after this connection is made that the dome operators will pump it full of air and raise the roof to its full height.

In short, the dome-building process can be summarized as such:

  1. Pour the concrete foundation.
  2. Insert the aluminum profile into the foundation.
  3. Spread the fabric out over the foundation and fasten it to the grade beam.
  4. Inspect the circumference of the dome to make sure everything’s secure.
  5. Inflate!

If all goes well, the foundation will do its job and keep the dome out of Mother Nature’s windy grasp.

And if disaster strikes and the dome does become airborne…well, at least it’s only the fabric that flies away. The concrete foundation isn’t going anywhere. In that way, air domes are actually the place to be in the event of a natural disasters. There’s no fear of the walls toppling over or the roof caving in over your head.

In any case, now you know why air domes don’t get blown away by the wind! Pretty neat, eh?


How Long Do Dental Handpiece Turbines Last?

The handpiece is, without doubt, the most important tool in a dentist’s arsenal.* At the heart of those essential tools are the dental handpiece turbines. It whirrs to life at the press of a button and spins at speeds of up to 400,000 rpm.

Like the dentist who holds it, a dental handpiece is only useful for as long as its mechanical ‘heart’ is beating. But how long do dental handpiece turbines last?

It’s an important question, given that these tools represent a large capital expenditure for dentists.

How Long Can You Expect Dental Handpiece Turbines to Last?

It depends.

It’s not all about the make and model, though that is a big factor.

There are so many variables that impact how long dental handpiece turbines will last. Many of these factors have to do with lubrication and sterilization. What type of sterilization you use, and how many sterilization cycles the piece is subject to each day, will impact the lifespan of the turbine.

What we can tell you is this: the typical handpiece can survive approximately 500 sterilization cycles without experiencing performance issues. Assuming you sterilize it twice per day, that is.

How do we know this? Because the United States Air Force Dental Investigative Service** did an extensive study on the issue. The Clinical Research Associates published a similar study years later, which yielded similar results.

Finding Repair Parts for Dental Handpieces

When a turbine stops working, rather than swallowing the cost of an entirely new handpiece, you have the option of replacing the old turbine with a new one (assuming the rest of the tool is still in good shape.)

Before the turn of the century, it was standard procedure to send a broken handpiece to the original manufacturer for repair. Today, thanks to wider availability, you have several options when it comes to finding repair parts for dental handpieces:

  • Option A: return the handpiece to the original equipment manufacturer.
  • Option B: purchase a new turbine from the original manufacturer and install it yourself.
  • Option C: purchase an aftermarket or generic turbine and install it yourself.

If you want to guarantee quality and consistency, option A is the way to go. However, depending on the manufacturer (and your relationship with them), this option could also come with significant labour costs.

Options B and C are more cost-effective, since finding repair parts for dental handpieces is easier than ever thanks to the Internet. However, you will only save money in the long run if you ensure the new turbine is installed properly. Otherwise, you could end up having to invest in a whole new handpiece. For this, you can turn to a local repair service for help.


*I think it’s fair to refer to a dentist’s range of tools an ‘arsenal’, given how sharp and pointy they are.

**Yes, this is a thing.


Plumbing And Heating Contractors Revealed

Diy Drone – Just The Facts

I love the sound of bagpipes myself even though I am of Native American and French origin. Lets take a look at what creates the unique sound of bagpipes.

All bagpipes are made with a bag, an air supply, and a chanter. More sophisticated bagpipes may also include more chanters and drones to enhance the sound. rov oil and gas industry.

The most common method of supplying air to the bag is by a blowpipe, into which the player blows. The blowpipe can be provided with a non-return valve, or the player can close the end of the blowpipe with their tongue while they breathe.

The chanter is usually open ended; thus, there is not the right way for the player to put an end to the pipe sounding easily. This means that most bagpipes share a legato sound where there’s no rests in the music. Embellishments (which vary between types of bagpipe) are employed to break up notes and to set up the illusion of dynamic effect primarily as a result of this inability to stop playing. These embellishments are often highly technical systems specific to each bagpipe which take much study to master as a result of their importance.

Most bagpipes have at least one drone. A drone is most usually a cylindrical tube with a single reed, although drones with double reeds do exist. The drone is designed in two or more parts, with a sliding joint in such a way that the pitch of the drone can be manipulated. Some drones have a tuning bead. These effectively alters the duration of the drone by opening a hole, allowing the drone to be tuned to two or more distinct pitches. The tuning bead may also shut off the drone altogether.

I hope this has helped you fully understand how bagpipes are able to provide the beautiful music that comes from them.
