Tech Tips:
I know I’m not the only one who has sometimes felt a little bad doing heat maintenance. I remember many a day when my lead technician and I (as an apprentice) would crawl into an attic, clean the flame sensor, and then play FarmVille on our phones for 15 minutes before crawling down, giving the […]

We recently received a Speakpipe question for the podcast about a common nuisance call on straight-cool A/C units and heat pumps. The systems, often retrofit units, were backing water up into the secondary drain pan and overflowing it. This issue isn’t happening on furnaces, which are positively pressurized, which means we have to take a […]

This tech tip is based on the podcast with Joey Henderson, “Using Refrigerant Troubleshooting Charts w/ Joey Henderson.” You can listen to that podcast HERE. The HVAC trade is very much a visual one; I wouldn’t recommend doing a drinking game where you take a shot each time you read “Do a thorough visual inspection” […]
