So far so good, when I write something up you guys don't have a problem with it.
I would like to know though is what exactly you guys look at when you do a yearly contract?
I have on numerous times seen systems that have been just serviced with rusted through flues, leaking ducts, Blocked condensation pipes where it was running out of the bottom, etc. Not trying to be a butt just curious of the routine. I know there are drive by techs just like inspectors.
Well I cannot speak for all of the HVAC guys out there, but my company has a "full service" check that we do for our bi-annual service. We do a visual inspection of the AHU (all components looking for signs of deterioration, heat, moisture, excessive dirt build-up, etc.), we check the venting and exposed ducts (for leaks, corrosion, and any other damage), we check the gas pressure entering and exiting the gas valve (gas only of course
), we check the amp draw of all motors and the entire system, we do a combustion analysis of the system to ensure proper efficiency, change the filters, we check the "delta T" to ensure proper airflow, and then we scrutinize anything that doesn't meet specs. We do the same thing in the spring for the AC side of the system (visual inspection, amp draw, "delta T", refrigerant pressures etc. etc.
That is how we service systems for our customers. Hope that helps you.
