Short-Cycling: Why It’s Bad News for an Air Conditioner

Monday, August 20th, 2018

It’s both a symptom of a problem and a problem itself. Although sometimes a few simple adjustments may fix short-cycling, if the root cause is serious it requires a professional HVAC technician to do the repairs. Unless short-cycling is stopped, it will eventually lead to an early replacement for an air conditioner and waste enormous amounts of power until then.

The Brutal Facts of Short-Cycling

Monday, February 5th, 2018

gas-energy-flamesIt’s not a fun situation to turn on your furnace during a cold day or night only to have nothing happen. The burners don’t ignite, and there’s no heat. There’s probably no danger in this situation, since modern gas furnaces are built to prevent an accumulation of unburned gas if the burners don’t come on. But you still have a non-working furnace and a freezing house.

What’s the problem? And is there anything you can do about it on your own? Let’s roll up our sleeves and take a look …
