Most of us have no idea how our HVAC systems operate.

And that's fine – an HVAC system is a pretty complicated feat of engineering and physics.
But here’s something you should know if you want to save some money on repairs.
Let me introduce you to the condensate drain line.
When this little puppy gets clogged, the system will freeze up – causing a failure in operation.
All you have to do is detach the line and pour in a cup of bleach or vinegar. This quick fix can help save you lots of money down the line!
How often you will need to clean the line will depend on how well you maintain the rest of the system, as well as the efficiency of your air filters, and the overall dustiness of the air in your house.
Keep those tubes clean people!

Most people never give a second thought to their HVAC system.

It cools me during the summer, keeps me warm during the winter, and keeps the air in my home fresh as can be…

But how can I maintain high performance?

You can start by changing the air filter every 3 months. This number can change depending on the climate, if you have any pets, and how old your HVAC system is.

Feel free to take a moment to ask us any questions you may have about your home's HVAC system, so that you too can stay cool this summer!

Ever notice how after a couple of years in the oval office, presidents start to look a bit haggard?
Well, not Mr. Herbert Hoover…
Hoover was the first president to enjoy the cooling powers of Air Conditioning:
He spent $30,000 USD on the system just months after the Stock Market Crash of 1929, and the beginning of the Great Depression…
Suppose he wasn’t yet asking what HE could do for his country ;)
Let us know – would you have spent that much money, at that time, if you were president?

As much as we love air conditioning, we are remiss if we don’t mention that excessive use of your air con machine can be harmful to the environment – yes, those greenhouse gasses!
Almost 90% of American homes use air conditioning – that’s 100 million tons of Carbon Dioxide every year…
Woah – so, the next time you’re out recycling, or considering a Tesla in place of your gas-guzzler, give some thought to an eco-friendly air conditioning system.
Give us a buzz or drop a note in the comments and we’ll help you explore your options :)

The first domestic Air Conditioner was installed in 1914. It was 7 feet tall, 6 feet wide, and 20 feet long!

Thankfully, since then we’ve reached a more manageable size…

How does air conditioning work anyways?

Certain compounds have the ability to cool the air as they evaporate.

Back in the 80’s, it was discovered that many of the chemical compounds used in air conditioning systems were destroying the ozone layer.

As you may know, this destruction allowed more deadly radiation from the sun to pe*****te our atmosphere, and harm the habitants of this planet – yes, that means you and me.

In 1989, the “Montreal Protocol” was put into effect, banning the use of a number of harmful refrigerants.

Since then we have discovered new compounds that achieve the same effect without harming our atmosphere.

How cool is that? 🧊
