Here's the conclusion first: Most facility managers don't lose money on HVAC because they pick the wrong vendor. They lose money because they pick the wrong technology category first. In my 12 years managing a commercial facility budget in Boston, the purchases that really cost us were rarely the ones with the highest initial quote. They were the ones with the lowest initial quote—and the highest total cost of ownership.
When we replaced our 260-ton chiller in 2023, the most expensive quote was a McQuay centrifugal chiller from a Boston McQuay HVAC service provider. The lowest quote was around $43,000 less—no, $41,800. I'd have to check my spreadsheet. Either way, we took the McQuay. For the first nine months, it looked like a budget mistake. Then I ran the TCO. The low-priced alternative would have needed a major compressor overhaul by year five. The McQuay's service contract, local parts availability, and historical downtime data put it ahead in year three. By year five, the gap was $18,600. The low quote was never going to be the low-cost purchase. Put another way: a low price tag is not the same thing as a low invoice.
Why I'm qualified to be suspicious of low quotes
I'm a procurement manager at a 90-person specialty food company outside Boston. I've managed our facilities budget—about $420,000 a year—for 12 years, negotiated with 30-plus vendors, and tracked every invoice in a spreadsheet that became our unofficial procurement system. I don't sell HVAC. I sign POs and then deal with the equipment when it complains. I built a cost calculator after getting burned twice by hidden fees: a 'free setup' that cost us $450, and a 'budget' compressor that ended up requiring a $1,200 redo when it didn't fit. The calculator now includes delivery, installation, downtime, service response time, and replacement cycles.
The most frustrating part is that the same logic keeps failing. You'd think after the third time an 'economical' choice failed, we'd stop repeating the cycle. But there's always someone at the table pushing the low-priced option. That's why I started writing these decisions down. (Should mention: we now require three quotes, but we also require a TCO sheet from at least one vendor—that's made more difference than the quotes themselves.)
McQuay centrifugal chiller: How local service flipped the math
If your building needs a big chiller in Boston, the right question isn't 'which brand.' It's 'who will be here when it trips on a Friday afternoon in July.' We standardized on a McQuay centrifugal chiller because the Boston McQuay HVAC service provider we work with keeps parts on a shelf and has a tech who knows the unit history. In Q2 2024, we had a chiller alarm at 4:15 p.m. on a 94°F day. The service provider diagnosed it remotely by 4:45, and had a part on site by 7 a.m. the next morning. That response doesn't show up in a spec sheet. But it does show up in the total cost.
Here's a counterintuitive detail: the higher first cost saved us money, but not because of a brand halo. It's because the service network around McQuay in New England is dense. Parts travel less. Techs have seen more installations. When I audited our 2023 spending, the most expensive line item wasn't the chiller. It was the three-week stretch when the old one was down. That downtime cost us more than the entire chiller replacement.
Heat pump dryer: What the pilot taught me
Honestly, I thought heat pump dryers were a residential thing. Then we needed to replace an electric resistance dryer on the packaging line, and an engineer suggested a heat pump dryer. I was skeptical. It's tempting to think 'hotter means faster,' but a heat pump dryer works by collecting and reusing heat, not by dumping hot air. We ran a 12-month pilot with a submeter. The heat pump dryer used 44% less electricity per batch than the resistance unit it replaced. The catch: it takes longer per batch. If you run at full capacity around the clock, cycle time matters. If you have partial loads or idle gaps, the energy savings can beat the slower cycle.
I should add that before this pilot, we didn't have a drying-cost tracking sheet. That was a process gap. We'd been running partial loads on a 60 kW dryer for years because no one quantified the cost. Fixing the process saved more than the machine did.
Infrared heater: Buy it for spots, not comfort
Infrared heaters are the product I'm most suspicious of, because the marketing makes them sound like magic. They're not. They heat objects and people, not the air. That's great for a maintenance bay with high ceilings and frequent roll-up door openings. It's terrible for a conference room. We installed two infrared heaters in our shop and used a programmable thermostat to cut back the forced-air unit. Over two winters, natural gas use in that zone dropped roughly 18%, which was about $1,100 in avoided heating cost. But it only worked because the space was drafty and intermittently occupied. If someone asks you to heat a whole building with infrared, be careful. Actually, let me rephrase: it's a smart spot solution, but it is still a spot solution.
Water heater vs boiler: It's not the equipment, it's the duty cycle
The 'water heater vs boiler' question always comes up when an old tank fails. Most people replace it with whatever was there, because the plumbing is already set up. I've done that too. That's exactly how we wasted money on a boiler that idled all summer.
Here's the rule I use: If you need 140°F water for handwash and cleaning, and you don't need steam, a direct-fired water heater is usually the better choice. It has lower standby losses than a boiler feeding an indirect tank because there's no heat escaping through the boiler jacket and piping all summer. In our plant, we replaced a 30-year-old boiler with a high-efficiency water heater for domestic hot water, and kept a smaller boiler for process steam. In Q2 2024, gas use for building heating was down 23% compared with the same quarter the year before. The counterintuitive part: the water heater's rated thermal efficiency was slightly lower than the new condensing boiler we'd priced. But the boiler would have been oversized for three months of hot water loads. An oversized boiler short-cycles and wastes fuel. The water heater matched the load better, so it won on operating cost.
If you need 180°F water for sanitation or process use, don't try to fake it with a bigger tank. That's a different conversation. And if you already have central steam, ripping it out to chase a water heater is a big capital bet—not a simple swap. But for many small commercial facilities, the answer is the water heater. The boiler is a solution to a problem you don't have.
Where this stops being true
I'll be honest: I was about to recommend this as a universal approach. It isn't. If you have central steam, keep it. If your heat pump dryer runs 24/7 at full loads, the longer cycle time can cost more than the electricity savings. If you need a whole warehouse warm, infrared won't do it. And if a vendor promises 'guaranteed energy savings' without showing you their meter data, ignore them. That's not a financial claim, that's a hope. Per FTC Green Guides (16 CFR Part 260), environmental and energy claims need substantiation. I now ask for 12 months of third-party submeter data before I'll put an energy claim into a capital proposal.
The next time someone hands you a low quote for HVAC equipment, don't ask what it costs. Ask what it will cost you. That's the whole job.
