Ran the numbers on a 40,000 sq ft warehouse last month. Owner was convinced their HVAC was the problem — bills had crept up 22% over two years, so they were about to drop $60k on new rooftop units.

We ran a thermal audit first. Turns out 30% of their ceiling insulation had compressed and lost most of its R-value from years of moisture cycling near the loading dock doors. The HVAC was working fine — it was just fighting a building that couldn't hold heat.

Fixed the insulation for under $9k. Bills dropped back to baseline within the first full billing cycle.

The pattern I keep seeing: commercial property managers troubleshoot energy bill spikes by replacing equipment before checking the building envelope. Insulation doesn't fail loudly — no error codes, no alarms. It just quietly degrades, and the HVAC system gets blamed for working harder than it should.

If your energy costs have crept up over 12-24 months and nothing else changed (occupancy, equipment, rates), get the envelope checked before you get a quote on new mechanical systems. It's usually the cheaper fix and it's the one people skip.

— Started ThermalShield to do exactly this kind of diagnostic work for commercial buildings. Happy to answer questions if you're staring down a similar bill spike.
