Maintenance with recorded readings, so condition is a trend and not an opinion

The difference between maintenance and a visit is the record. If nobody wrote down the static pressure, the temperature split and the amp draw, then next year nobody can tell whether anything changed.

Every visit produces numbers, and the numbers go in your log.

A written task list per unit, with acceptance criteria

Each piece of equipment on the agreement gets its own task list: what is checked, at what interval, and what the acceptable range is. Not a generic tick sheet that could belong to any building.

The acceptance criteria are the useful part. "Checked belt" is not information. "Belt tension within range, replaced, next check April" is.

The readings we take every visit

Total external static pressure, supply and return temperature split, compressor and fan amp draw against nameplate, refrigerant superheat and subcooling, gas manifold pressure, and filter differential pressure.

Those six things, tracked over time, tell you almost everything about a machine before it fails. A compressor drawing 8 percent more than it did eighteen months ago is a conversation. The same reading with no history is a shrug.

The log is yours and exportable. If you replace us, you keep it.

Filters by measured pressure drop, not only by calendar

Filter changes on a fixed schedule are either wasteful or late, depending on the building. We record the differential pressure across the filter bank at each visit and set the change interval from the trend.

For MERV 13 in a deep rack that often means longer intervals than the calendar suggested, and better filtration than the building had before.

Capital planning, a year before you need it

The annual condition report gives every unit a remaining service life estimate and flags anything within three years of replacement, with an indicative cost.

The point is to let a facility manager put a number in a budget in September rather than raise an emergency requisition in July. Refrigerant records under EPA 608 sit alongside it, which matters more each year as R-410A supply tightens.

Dust, dry air and a hard July

Front Range summers put condensers under sustained high ambient load, and the dry, dusty air fouls coils faster than the maintenance intervals written for wetter climates assume. Coil cleaning intervals here should be set from what the coil looks like, which is why we photograph it.

Questions we get about this.

If yours is not here, ask it directly. You get an answer from the engineer who would run the job, not from a call centre.

All questions
Do you take on work you did not design?

Yes, for service, maintenance agreements and repairs. That is most of what a mechanical contractor does.

For a replacement we will always re-run the load and measure the existing distribution before quoting, even if the equipment is a straight swap on paper. It is the only way to avoid inheriting somebody else’s sizing error at a higher price.

If the honest answer is that your existing system has years left and needs a repair rather than a replacement, that is the answer you will get.

How quickly do you respond to a breakdown?

Maintenance agreement holders get a four hour response target during business hours and 24 hour coverage, including weekends and holidays, with a named account engineer who already knows the building.

Without an agreement we schedule against available capacity, which in a July heat event or a January cold snap can mean a wait. That is not a sales tactic, it is arithmetic about how many trucks exist.

Every visit, agreement or not, ends with recorded readings in your log rather than a verbal summary.
