Heating Season?

In the upper Midwest, the leaves  on the trees are turning beautiful colors, the morning air has a little “chill” to it, and people are starting to turn on their heating systems, both commercially and residentially.

Now comes the time to get our mindset off of air conditioning and start thinking about heating, ignition controls, diagnostics and servicing.

We need to remember how to measure manifold pressures on the gas valve.  We need to remember how to measure microamps and what is the correct reading for that heating control. We need to remember how to measure “temperature rise” through the furnace. And, we need to remember how to measure the pressure drop through the furnace.

So why are these 4 items above so important to servicing heating?  Simply put — these are the basic diagnostic items that will help you solve most heating problems.

In my next few posts, we’ll look at these items and go into detail on how to perform the check and what they tell you about the system. So stay tuned.


About yorkcentraltechtalk

I have been in the HVAC industry most of my life. I worked 25 years for contractors on anything from residential to large commercial boilers and power burners. For the past 23+ years I had been employed by York International UPG Division ( a division of Johnson Controls) as a Technical support/Service Manager but I am now retired. One of my goals has always been to "educate" dealers and contractors. The reason for starting this blog was to share some knowledge, thoughts, ideas, etc with anyone who takes the time to read it. The contents of this blog are my own opinions, thoughts, experiences and should not be construed as those of Johnson Controls York UPG in any way. I hope you find this a help. I always welcome comments and suggestions for postings and will do my best to address any thoughts, questions, or topics you may want to hear about. Thanks for taking the time to read my postings!
