Often nothing needs to be bought. The installation is already there, but it runs on default settings, outside working hours or against another system, heating and cooling the same space at once. We check sizing, settings, controls and how equipment works together before proposing any replacement.
What we check
- Heat pumps and heating. Short cycling, flow temperatures, backup heaters, flow rates, hydraulic balancing and how heat sources work together.
- Ventilation. Schedules, pressure losses, filters and heat recovery.
- Refrigeration. Set points, defrosting and heat rejection.
- Compressed air. Leaks, pressure and compressor control.
- Electrical installation. Loads, power quality and how loads interact.
- Controls. Unnecessary operation outside working hours and simultaneous heating and cooling.
How we work
We start with operating data and a site visit, and measure over a representative cycle that includes nights and weekends. Each proposed change is assessed together with its effect on the other systems.
What you get
A description of the causes, a list of recommendations (adjustment, repair or upgrade) with costs and expected effect, and a way to check the result after the changes. If an investment is not justified, we say so.
When it makes sense
- The bill went up although the building is used the same way.
- The heat pump cycles on and off often or the backup heater runs a lot.
- Ventilation or air conditioning runs when the building is empty.
- Compressors keep running after production stops.
