At the turn of the 20th century, Sackett & Wilhelms Lithographing Company, a printing plant in Brooklyn, New York, had a problem: High humidity was causing its paper to wrinkle, swell, and shrink. As a result, the company was dealing with misaligned prints, jammed equipment, and long drying times. So it called on the heating and fans division of Buffalo Forge Company for a solution.

The task fell to mechanical engineer Willis Carrier, who was head of experimental engineering at Buffalo Forge. Because cold air can hold less water v***r, Carrier focused his efforts on cooling the factory down. Buffalo Forge already manufactured heating coil systems — fans that distribute hot air from steam-filled tubes — to heat buildings, so, Carrier reasoned, why not run cold water through the coils instead?

He installed the first modern air conditioning system in 1902, and his experiment was successful — most home air conditioners function on this same basic principle. But the system didn’t operate on the level that Sackett & Wilhelms needed it to. So Carrier got to work on something that could actually meet the needs of a large factory, and developed the first spray type air conditioner, a large enclosure filled with water nozzles that could cool hot air before sending it back into the factory. The cool air, even though it came from a wet environment, could hold less water, so it successfully reduced the overall humidity.

Are we in false-spring or is real-spring on the way?
We don’t know but what we do know is it’s time for your air conditioner maintenance checks! There are tasks you can do at home yourself however to be safe, leave it to us professionals and call us today to schedule your annual air conditioner maintenance tune-up appointment! (608) 437-3666

Key air conditioner maintenance tasks:
•Clean or replace air filters:
This is the most basic maintenance task, done every 1-3 months to maintain airflow and energy efficiency.
•Clear the condensate drain:
Regularly check and clean the drain line to prevent water leaks.
•Inspect the outdoor unit:
Remove debris from around the outdoor unit to ensure proper airflow.
•Adjust thermostat settings:
Set the temperature higher when you're not home to reduce energy usage.
•Professional maintenance:
Schedule an annual check-up with an HVAC technician for a thorough inspection and tune-up.

When to get an AC tune up:
•In the spring before the peak cooling season.
•If you notice your AC is making strange noises, leaking water, or blowing hot air.
•If your utility bills have increased.
•If you notice excess humidity levels.
•If your AC is no longer cooling your home as well as it used to.

Thanks for thinking of our company.

HUGE shout out to Olson Heating Cooling & Appliance in Mount Horeb. It is a bummer to be without AC, it is a real bummer when you are doing this. All these athletes cheered when it came back on. Olsen’s got it fixed fast.

Geothermal energy is a renewable resource harnessing the power of the sun absorbed by the earth daily! Approximately 48% of the sun's energy is absorbed by the ground and stored, making it an abundant and sustainable source of power. By tapping into this natural energy reservoir, geothermal technology offers a clean and reliable solution for heating and cooling our homes. Let's harness the sun's energy beneath our feet for a brighter, greener future!
