How commercial HVAC actually works, and how to buy it well.
A distribution center in Taylor ran three dock doors open for most of a shift during peak receiving season, and the facilities manager assumed the resulting temperature swing near the docks was…
A metal fabrication shop in Wixom added a large exhaust fan to pull welding fumes out of a production bay. It solved the air quality complaint it was meant to solve. It also created a problem…
A grocery store manager in Warren couldn’t figure out why the front of the store stayed cold enough for customers to keep their coats on while the back of the store, near the deli counter, ran…
A congregation in Sterling Heights was paying to heat its 400-seat sanctuary to a comfortable 70 degrees around the clock, every day of the week, even though the space saw meaningful use for…
A climate-controlled self-storage facility in Madison Heights sat with a failed rooftop unit for eleven days before anyone noticed, because the building had no daily staff presence and the failure…
A dealership in Auburn Hills replaced its aging service bay heaters and, in the same project, asked the contractor to also look at why the glass-walled showroom out front never seemed to hold a…
A second-run movie theater in Westland kept fielding complaints that auditoriums felt stuffy toward the end of a showing, even though the ventilation system had passed inspection and appeared to…
A property management firm based in Troy overseeing eleven commercial buildings across Southeast Michigan was working with seven different HVAC contractors, one per building or region, largely…
A developer converting a 1920s bank building in downtown Ypsilanti into office space ran into a problem the architectural drawings never mentioned: there was nowhere to run a duct without cutting…
A limited-service hotel in Dearborn was burning through an unusual amount of natural gas every winter, and the general manager assumed the boiler plant needed replacing. The boiler was fine. The…
A strip mall owner in Rochester Hills couldn’t understand why the fitness studio that replaced a former nail salon kept filing complaints about stuffy air, when the space had passed its original…
A retail plaza owner in Novi signed off on installing six Level 2 electric vehicle (EV) chargers in the parking lot without ever calling the company that services the building’s rooftop units….
A 40,000-square-foot office building in Dearborn runs four rooftop units, all installed in 2012. In July, one failed outright. A stuck compressor, no warning, ninety-seven degrees outside, and…
A general dentistry practice in Sterling Heights that had converted a former optometrist’s suite into a five-operatory office two years earlier ran into it during a routine state licensing…
A tenant on the fourth floor of a 40,000-square-foot office building in Auburn Hills filed a complaint that had nothing to do with temperature. They wanted proof the system was actually pulling in…
A 22,000-square-foot medical office building in Livonia replaced two aging rooftop units last fall, along with the controls and filtration that came with them. The efficiency gain was real and…
A 60,000-square-foot office building in Novi renewed its commercial property policy this spring at a premium 18 percent higher than the year before, and the increase had nothing to do with a…
A 40-foot ceiling changes every assumption a normal HVAC conversation starts from. Warehouse and industrial heating is not a smaller version of office heating scaled up. It is a different problem,…
An IT director we work with at an insurance office in Troy got the call at 6:14 on a Saturday morning: the server room was reading 91 degrees. The building’s single cooling unit, a ductless…
A property manager called us about a single tenant complaint: Suite 220 was cold. The technician started there, then traced the zone damper back through three other suites, a shared return path,…
Every few months a building owner asks us some version of the same question: should we just switch to heat pumps? Last winter it was the owner of a 35,000-square-foot office building in Farmington…
A facility manager we work with in Southfield found out the hard way that his Building Automation System (BAS) had been overriding a stuck damper for six weeks. The dashboard showed green. The…
You have seen this happen to something you liked before. A restaurant you loved gets bought by a larger group. The menu shrinks. Prices go up. The staff turns over. The thing that made it worth going, the specific people, the particular care, the sense that someone with real skin in the game was running […]
At some point, every building owner has the same conversation with their HVAC contractor. The system is struggling. A repair is possible but not cheap. The unit is old enough that another problem is probably coming. The contractor recommends replacement. The building owner does not know if that is the right call or a convenient […]
Most building owners sign HVAC service contracts the same way they sign most vendor agreements. They skim it. Compare the price to last year. Sign. The scope feels standard. The language feels like boilerplate. The relationship feels fine until it is not, and by the time it is not, you are stuck in a contract […]
You cannot see bad indoor air. You feel it. Tenants call and say they have headaches. Employees seem to get sick every winter, more than they should. The building feels off in a way nobody can quite articulate. These complaints are easy to dismiss until a health department flag or a liability claim turns them […]
If you own or manage a commercial building of any size, at some point the question comes up: which system belongs in my building? Maybe you are replacing aging equipment and a contractor is recommending something different than what you have. Maybe you are taking over a building and trying to understand what you inherited. […]
Most commercial building owners have heard something about refrigerants changing. The details are usually fuzzy. Something about the EPA. Something about phasing out. The equipment still runs fine so it does not feel urgent yet. Here is the version worth understanding: this transition is already underway, it directly affects repair costs and equipment availability for […]
Getting multiple bids on commercial HVAC work is the right thing to do. The problem is that most building owners evaluate those bids by looking at the bottom line, comparing it to the other bottom lines, and picking the lowest one that comes from a contractor who did not seem obviously bad during the walkthrough. […]
The commercial HVAC industry is short approximately 110,000 technicians nationally. About 25,000 leave the workforce every year through retirement, burnout, or career changes. The number entering the field is not keeping up. According to the U.S. Bureau of Labor Statistics (BLS), HVAC jobs are projected to grow 8 percent between 2024 and 2034, which sounds […]
Variable refrigerant flow is one of the more frequently misunderstood technologies in commercial HVAC. It gets recommended sometimes when it should not be and dismissed sometimes when it should not be, often by contractors who have a strong preference for whatever they install most frequently. VRF is genuinely the right system for specific building types […]
Most building owners with cooling towers understand them at a surface level. Water goes up, heat goes out, the building stays cool. The mechanical reality is more specific than that, and the maintenance stakes are considerably higher. Skip cooling tower water treatment and you are not just losing efficiency. You are creating conditions under which […]
A restaurant heating and cooling problem almost always turns out to be a ventilation balance problem. The two look different on the surface, but once you understand how a commercial kitchen mechanical system is supposed to work, you see how often they are the same thing. A dining room that cannot hold temperature. A kitchen […]

Get ahead of failures before they turn into emergencies.
A technician was called out to a Pontiac office building for a rooftop unit that had been running longer cycles than normal, and the initial diagnosis leaned toward a refrigerant issue. A…
An office building in Troy ran its rooftop units in mechanical cooling mode through a stretch of mild 55-degree spring mornings, compressors and all, while the building’s own economizer damper sat…
An office building in Pontiac spent six hours blowing hot air into a 78-degree afternoon in late April. The heat pump was still locked in heating mode from the night before, and the reversing…
Here’s a scenario that plays out at school districts across Michigan more often than most facilities teams expect. A district’s voters approve a bond for HVAC replacement in November. Two rooftop…
There is a phone call we get more than we would like. It comes in late on a Tuesday, or early on a Saturday when the building is already full. The system quit. Nobody knows when it was last serviced. There is a tenant meeting in two hours and the building is warming up fast. […]
There is a version of this story that ends with a $400 service call. There is another version that ends with a compressor replacement, three days of building disruption, and an invoice that clears $10,000. Same equipment. The difference is usually just time. Commercial HVAC systems almost never quit without warning. The warning just looks […]
A building owner called us this summer. His energy bill had climbed $800 a month over the previous year and he could not figure out why. He had already called the utility. He had looked at the lighting. He had done everything except look at his HVAC equipment. It was a fouled condenser coil and […]
Michigan is not a mild climate for HVAC equipment. Anyone who has spent a winter here already knows that. But the part of the Michigan climate that does the most cumulative damage to outdoor commercial equipment is not the cold itself. It is the transition. The freeze-thaw cycle, the repeated movement between above and below […]
Michigan sits on the Great Lakes. Most people who live here know what that means for summer. What fewer people connect is what it means for their building year-round. Southeast Michigan's humidity challenge runs in both directions and across every season. Summer brings moisture loads that most commercial HVAC systems struggle to keep up with. […]
Every summer, commercial HVAC contractors across Southeast Michigan respond to the same wave of emergency calls. Rooftop units that were fine in April fail in June. Buildings that had no issues through winter go down on the first genuinely hot week of the year. Facility managers who were not thinking about their HVAC systems in […]
A boiler failure in January in Southeast Michigan is a different category of problem than almost any other HVAC emergency. An air conditioning failure in July is disruptive. Tenants complain. Business is interrupted. It needs to be fixed urgently. But the building stays above freezing while you sort it out. A heating failure in January […]

What to do when something is going wrong right now.
A property manager in Royal Oak spent three weeks treating a tenant’s noise complaint as a customer service problem. The tenant, a five-person law office on the fourth floor, said their conference…
A commercial-grade portable air conditioner runs about $90 a day to rent. Smaller, standard-capacity units cost less, commonly $20 to $80 a day, depending on British Thermal Unit (BTU) capacity…
You called. You got a callback window of tomorrow morning. The building still needs to function tonight or through the weekend, and you need to know what is actually possible in the meantime. The answer depends on the season and how bad the situation is. If the Cooling Is Out in Summer Start with who […]
The repair is done. The bill is paid or about to be. The building is running again and you are looking at a number that was not in the budget. The temptation after an expensive repair is to put it behind you and move on. That is usually the wrong call. The repair just gave […]
An inspection violation on commercial HVAC equipment lands differently than a failed maintenance visit. It comes with paperwork, a compliance window, and in some cases an immediate shutdown order. Most building owners have never dealt with one and do not know how serious their specific situation is until they read it closely. Here is how […]
The technician called. The compressor is gone. You have a quote for the repair and probably a suggestion about replacement, and you need to make a capital decision without a lot of time to think about it. This is one of the most common expensive decision points in commercial HVAC. Here is how to think […]
You called two hours ago. You have gotten one callback and a window of "we will try to get someone out today." The building is uncomfortable and getting worse. You want to know why this is taking so long and whether there is anything you can do about it. The answer involves the state of […]
A carbon monoxide alarm in a commercial building means one thing: get everyone out. You do not investigate it. You do not decide how serious it is. You act immediately. That is the correct response to a gas that is colorless, odorless, and lethal at concentrations that build faster in commercial buildings than most people […]
The technician found a refrigerant leak. They have told you the system is undercharged and located the leak, or they have told you they cannot find the source yet. Either way, the visit that started as something else just got more complicated. Here is what you need to understand before you decide what to do. […]
Ice on a rooftop unit looks wrong. It is wrong. A system that is supposed to cool a building should not be growing ice on the equipment, and when it does, it means something has gone sideways in the refrigeration process. Here is what is happening and what you can do before the technician arrives. […]
A tenant complaint about temperature is not always an HVAC emergency. Sometimes it is. The problem is that from the moment the call comes in, you are making decisions with incomplete information, and calling a contractor immediately is not always the right first move. Here is how to triage a tenant temperature complaint before you […]
The system is down. The building is warming up or cooling down depending on the season, tenants are already calling, and you need to know what to do in the next hour, not a general overview of how HVAC works. Here is the sequence. Work through it in order. The First Fifteen Minutes Check the […]
You are holding a quote for an emergency HVAC repair. The number is higher than you expected. You do not know enough about commercial HVAC to know if this is what it costs or if you are being taken advantage of. And the technician is standing there waiting for an answer because the building is […]
A commercial building without heat in Michigan January starts accumulating damage within hours. Most building owners understand a heating failure is urgent. Fewer know exactly how fast the clock moves or what the sequence of consequences looks like. The Temperature Drop Timeline How fast a building cools depends on insulation quality, ceiling height, window-to-wall ratio, […]
