I asked my neighbor who hoses off his air conditioner condenser every spring why he does it. “Because my dad always told me I had to,” he said.
Conventional wisdom like what my neighbor’s dad imparted may always seem right. But through my HVAC scholarship – the study of heating, ventilation and air-conditioning systems – I’ve learned that this particular presumption is probably wrong.
The equipment I’m talking about washing is the outdoor part of central air-conditioning systems that move heat from homes into the outdoors.
Technically known as condenser coils, they are usually about the size of a large garbage can but they can be as small as a bucket or as big as a refrigerator. Some are protected by louvered grilles but most are exposed to the elements. Their metal fins help transfer heat to the air. They contain tubes that carry the hot refrigerant, which gives off heat as it condenses.
Stuff like windblown seeds, dust and grass clippings tends to collect on the coil surface. Most homeowners and HVAC companies envision that this untidy-looking stuff acts like an insulating blanket, slowing down the passage of heat from inside to outside. Any debris that accumulates would also interfere with airflow over the coil, further restricting the system’s ability to expel heat.
Mehdi Mehrabi, an architectural engineering graduate student, and I set out to learn the extent to which dirty residential air conditioners are less efficient than clean ones. What we found astonished us – and many of the other experts in this field.
Have you played Monopoly lately? Or maybe snakes and ladders? These board games are examples of 100-year-old games that many still play today.
But the way they are played today may not be teaching the lessons their designers hoped to share.
At the start of the 20th century, children were part of the regular workforce. They possessed few toys. When U.S. manufacturers created games, they built them to market to parents: to teach as well as to entertain.
If you are a fan of the Toy Story series by Disney – Pixar then you will want to plan a date with a theater beginning June 21 when Toy Story 4 is scheduled to release.
Toronto-raised Keanu Reeves is set to voice Duke Caboom in the upcoming fourquel.
Caboom is a vintage 1970s-era toy, inspired by Canada’s greatest stuntman. Perched atop his powerful Caboom stunt-bike, Duke flashes off his stunt poses with confidence and swagger, but he has one itsy-bitsy problem: he can’t actually do the stunts advertised by his own commercial. Weighed down by the failures of his past, he has some serious identity issues when he encounters Woody (Tom Hanks) at an antique store.

Woody has always been confident about his place in the world and that his priority is taking care of his kid, whether that's Andy or Bonnie. But when Bonnie adds a reluctant new toy called "Forky" to her room, a road trip adventure alongside old and new friends will show Woody how big the world can be for a toy.
The sun was high when I walked through the door, Esther just arched her eyebrows and asked, “Breakfast or lunch?”
I’m sorry I’m late”
mind that Simon, Eli told me what happened.
You must be exhausted, you fished all night and then you are gone all
morning. Where were you? What is happening?” Breakfast or lunch?”
some bread and olives will be fine, we cooked some fish for breakfast and ate
while we talked.”
what did you talk about with this Jesus? How to build a table or fit at door? Or were you teaching him how to fish? What do you even have in common with this man?”
The questions rolled out, one after another.
Great article in the Toronto Sun by Bill Walker, Ontario minister of Government and Consumer Services.
Like most Ontarians, I was shocked to read that a family in Ottawa – the father, a third-generation member of our Armed Forces and a veteran of the War in Afghanistan – was told by a condominium board they were not allowed to fly the Canadian flag on the front of their house.
For those of you who may be unfamiliar with the story, Maj. Michael Mitchell initially put up our nation’s flag to celebrate Canada Day and kept it flying until he was told this week it violated the rules of his condominium corporation.
The board informed Mitchell that no condo owner was allowed to affix anything to the front of their home. Mitchell and his family were not initially aware of these rules
Hats off to the Qantas CEO who treated this young boy’s request with dignity and respect. It’s a beautiful story that may bring a smile to your face or a tear to your eye.
Alex Jacquot is a 10-year-old boy who lives in Australia. He’s also an aspiring airline CEO, who wrote a letter last month to Qantas Airways CEO Alan Joyce, asking for advice on getting his future company off the ground.
He starts it off by introducing himself and asking the CEO to please take him seriously. After all, he’s already the CEO of his very own airline, which he’s named “Oceania Express.” He’s also already hired a CFO, a head of IT, a Head of Maintenance, a Head of On-Board Services, and a Head of Legal. And he’s got a co-founder in the form of his friend Wolf. Oh, and he’s already “started some stuff, like what type of planes I’ll need, flight numbers, catering and more.”
The first signs of a problem started to emerge around 2014: More young people said they felt overwhelmed and depressed. College counseling centers reported sharp increases in the number of students seeking treatment for mental health issues.
Even as studies were showing increases in symptoms of depression and in suicide among adolescents since 2010, some researchers called the concerns overblown and claimed there simply isn’t enough good data to reach that conclusion.
The idea that there’s an epidemic in anxiety or depression among youth “is simply a myth,” psychiatrist Richard Friedman wrote in The New York Times last year. Others suggested young people were simply more willing to get help when they needed it. Or perhaps counseling centers’ outreach efforts were becoming more effective.
