    Got a call 1 hr. before closing on a Fri that a school's dish machine wouldn't fill good and they had to use a hose. They wanted me there right now. I get there and ask when did the problem start. They say, we've been fighting with their maintenance guys for over a year on this. They adjust something in the boiler room and leave and it's never any better. PRV under the sink was packed with rust and gunk.

    Another Fri afternoon. a different school called. They had a horrible noise above their kitchen in the high school and the light in their walk-in in the elementary school didn't work and their guys couldn't figure it out. I get there and they turn on the exhaust fan. RUMBLE RUMBLE RUMBLE. They said "we started hearing something on Tuesday but we didn't call until it got too loud to talk in the kitchen!" I got the maintenance supervisor to take me to the roof. He says 'Yeah we started hearing it on Tuesday" I open this fairly new looking fan and there is no grease on the bearings. I grease it up and measure everything to order new ones. Now I go to the other bldg and cooler light. No power to the socket. I open the temperature indicatator /light switch and jump the switch terminals. Light comes on.

    "Insufficient cooling" call for a new install. I push down the thermostat (from 78F) and get 55F supply air. Start asking the usual questions, ending with, "But if you lower the thermostat, you are comfortable?" Owner of business answers, "This system should provide comfort at a 78F set point". Is this person a lot dumber then they look, or are they "asking" me to "recalibrate" their thermostat so they can brag how "green" they are? I'm not their mother, so I "calibrated" the stat and left the equipment running (both of us were running, me AND the package unit...)

    Dialysis center with "too cold" complaints. Temperature dead on setpoint. But the medical director points to the supply grilles (8 foot ceilings) and says "We want it 73F in here, and that air is 56F!". I feel their pain. All those dialysis machines producing heat that need cooling, all those patients with their blood being sucked out of them. Not a "service" problem, but an "engineering " problem. (Direct cool your equipment, or raise the ceilings a couple of feet, just add a couple of zeros to my "not to exceed " and I can make your nightmares go away)

    "I've got a light that's shorting out"

    I go over there and take a look...the bulb is flickering...check socket and there is no corrosion or pitting..."Get me another light bulb"

    Install new light bulb, and whala problem solved.

    I didn't charge anything because I like the guy and the whole thing proves a really good point. Sometimes you can get so focused on the weirdness of what is happening that you forget to focus on the basics. I learned that valuable lesson the hard way on a POS Range Rover with a fuel trim problem. As soon as you get overly focused on the complexity/weirdness of the symptom you get distracted from the calm, collected, and systematic thought processes that make troubleshooting successful.

    23 years of hvac and controls service I have so many of these!! I really like people, and customer service is big part of it. But it's getting increasling harder to be nice. A couple of my favorites.

    1. Respond to a large building with 100 ton trane sitting on the roof. Complaint every minute or so the hole building shakes and the rootop unit is causing it. I go one the roof and cycle the fans, compressors ,everything I can think of and can't find anything. I return to the customers office walking into the office I'm facing the window watching a large track hoe threw the window with a compactor attachment move towards the hole where a new building is being built. Just then the guy lowers it and compacted the ground, and yes the building shook!! He's says thats it!! That's it!! I said yes I found your problem and pointed out the window. The look on his face was great.
    2. Not proud of this one, and it almost cost me my job. Responded to a service call which ended up requiring me to trace pneumatic tubing from space to space in a office builiding. I entered one space introduced myself and let the boss guy know what I was doing then proceeded to open more ceiling tiles. I had to return the space where I had started and left the other tiles out. Once back in the other office and in the ceiling looking around the door flies open, and the boss guy from the other office is pissed!! Yelling at me what kind of idoit leaves a huge mess, and a bunch of other nice comments. Trying to calm the guy down I explained I wasn't finished and would return with a vacuum and clean it up. He slams the door and calls me another nice word. Back in his office with the vacumm on the floor is about 3 small chunks of ceiling tiles which set this guy into a tail spin. I said this really ruined your day?? His comment was l'm calling your boss!! My response was I would call 911 first, and reserve your ambulance. Well not my finest moment for sure!! In a long customer service career I've been lucky to work for some great people, but on rare occasion have been treated like trash for reasons I've never figured out.

    What is fun about air balance is you can make the jerks pay for their stupidity. I was balancing a large library and when I got to the head guys office he told me that balancing the building was stupid because in about 3 years they were going to redesign the entire HVAC system. I told him I didn't know anything about that but we had a contract to do the balance now because of work that was just finished on the systems. He said he was going to call my boss and find out what was really going on. I told him I owned the company and had already told him what I knew. He got really pissed and told me to get the hell out of the building. I did after I set the airflow on his VAV low enough to roast his rear.
    As it turns out he lost his job because he didn't have any say about the contracts and his interference was the last straw. Him running me off the job was actually good for me because the engineer had undersized the chillers and I was going to pull off the job anyway until they figured out what to do. The chillers were ground source and there was nowhere to sink additional wells. I was called to finish the balance 3 months later and discovered all the AHU'S had been slowed down in an attempt to not overload the chillers. I ask how much and what were the new airflows? Nobody knew so after a week of deliberating they said do with it whatever you think will work and don't worry about the report being rejected. I did and never got a complaint but the engineer hates me to this day for pointing out the chiller screw up.
    At least Trump doesn't eat dogs!!

    -Room is cold but thermostat was reading 130 deg. I show up and find that someone had made their way into the configuration settings and changed the temperature offset all the way up to 72 thinking it was the setpoint. Set it back to zero and space read 58 deg and started heating.

    -Show up to a cold site. No maintenance guy. Guy who called us escorts me around. "Who's cold?" -I don't know- "Where are the boilers?" -I don't know- "Do these VAVs have heat?" -I don't know- etc.

    -Been fixing a lot of remodels lately. Contractors move equipment around and rewire it with anything lying around. Bacnet wire is the same as 18/2 right?

    -Vav box is not heating. Open up electrical portion and wire nuts everywhere. Fuse blocks replaced with whatever and screwed into sheet metal. Black marks on metal, black wires. Take picture, shut box, walk away.

    -RTU not cooling well. Go onto roof. Outside metal filters sucked into unit. Regular filters sucked in. Compressors screaming.

    Guy called emergency service at 6:30 am, didn't really explain what was wrong just requested a technician. No one was dispatched as custom was to ignore emergency service calls that were too close to starting time (7:00 am) and let dispatch catch it when they came in, unless it was a hospital with a major issue or something like such. Was a slow day for me so I was in the office that morning. Walk up to dispatch and ask if they have anything and they hand me this guy's ticket. Site was close so I head over, mind you with no idea what is wrong as the ticket was pretty much blank.

    Get to the site call the guy and he gets me into his office/electrical/BAS room. Logs in and shows me a RTU that he says was always too cold in the morning and too hot in the afternoon. We go out into the space and it is a big open office with a few cubicles but mostly empty. I figure the RTU is just struggling with the position of the stat and the lack of load. We go back to the workstation and I start poking around and the guy had managed to override the zone temperature, not the setpoint the actual AI value. Course he claims he didn't do it and I didn't feel like making him wrong by going through the audit logs.

    This guy called after hours emergency service for an area that had almost no people in it in a office building. I know that the after hours call center is supposed to explain the rates for emergency service and have the customer agree to the 4 hour minimum. So this guy was willing to pay upwards of $300/hr for a minimum of 4 hours for an overridden zone temp.
