Cold weather is one of the problems that residents of Rancho Cucamonga don’t always have to deal with. With warm summers and balmy winters, freezing temperatures and the problems associated with it are usually far from mind. Recently, however, induced by a polar vortex, a cold snap swept into the country, sending temperatures across the entire United States plummeting to record lows.
Rancho Cucamonga, like the rest of the state of California, was not spared. Although the mercury did not fall below freezing, cool air wafted into the city and quickly dropped the temperature a full 14 degrees over the course of a week.
An article from the Charlotte Observer recorded how the cold weather has spiked demand for HVAC specialists in North Carolina due to the increasing number of people calling in to have heating and air conditioning units damaged by the sudden chill repaired.
Freezing temperatures or not, cold weather will still inevitably affect air conditioning in Rancho Cucamonga. Cold snaps may not have effects as extreme, but they can still play havoc on the heating and AC systems, and companies like Day Aire HVAC, inundated by repair calls, are once again busy helping homeowners and businesses get their HVAC systems back up and running.
The very nature of AC systems make them especially vulnerable when winter’s chilly hands take grip. In the warmer California weather, pumps in the system move water between the heat exchangers that cool a building and expel hot air outside. When cold weather suddenly draws in, these pumps stop to keep the building from cooling further, and the water in the pipes can freeze—usually causing the pipes to burst.
Also, with the AC system ground to a halt, dirt can accumulate unchecked in the filters. This reduces the air’s ability to flow freely through the system, causing fans to work extra hard and burning out their circuitry.
Ductwork can also suffer due to the cold weather. Sudden changes in temperature can cause the materials on air conditioning ducts to become brittle. They then break catastrophically due to thermal expansion and contraction.
To help mitigate the risk of Rancho Cucamonga air conditioning systems failing due to the cold snap, specialists often recommend making filter inspections regular even when it isn’t running. To avoid thermal expansion problems caused by sudden changes in temperature, it’s also a wise idea to idle the system for a few minutes when switching between heating and cooling modes.
