The first call of the morning is the expensive one

Ridgeline maintains heating, cooling and ventilation for buildings that have to open on time — and for the houses of the people responsible for them. A good share of the call-outs we are asked to attend are not faults at all, and we would rather you knew which.

Six call-outs that were not faults

A building cold on Monday morning. A system that ran all weekend. A tenant complaining while the others are fine. Every one of them has a cause that is a setting rather than a failure, and every one of them gets paid for as a failure.

What the page gives you

For each of the six: what it usually turns out to be, what to check before anybody drives out, and the specific circumstances in which it genuinely is a fault and needs a visit.

Why we published it

Because an after-hours call-out that ends in somebody pressing a button on a controller is a bill nobody enjoys sending. We would rather have the maintenance agreement and fewer of those.

Facilities

Buildings that have to open on time

Retail, light industrial, professional suites, clinics and warehousing across Arvada, Westminster and the north-west metro. Surveyed first, then maintained against the survey.

The survey

A written page per unit: where it is, what it serves, its real age from the serial number, its condition, and what stops trading if it stops. One visit, and everything else depends on it.

Planned maintenance

Two visits a year with fixed content, readings recorded per unit, and a sheet afterwards with anything urgent priced separately from anything coming.

Controls and schedules

Read against how the building actually trades, not against what was set on the day it went in. This is where most of the six false alarms start.

Rooftop units

Coils, belts, bearings, economisers, condensate and the curb. Most of what shortens an RTU’s life happens outside it.

Extract and make-up air

Kitchens, workshops and salons — and replacing the air being thrown out, because a building in depression pulls at every flue in it.

Fit-out and commissioning

Airflows balanced and recorded, controls set to your hours, and the figures handed over. A space nobody commissioned never performs.

Homes

Houses get the same instruments

A furnace in an Arvada house is combustion tested with the same analyser we take onto a roof deck, and a bedroom that never keeps up gets the airflow measured rather than argued about.

Gas heating, air conditioning, evaporative cooling, heat pumps, duct sealing, and the finished basement that unbalanced the rest of the house. Altitude checked against the manufacturer’s instructions for the model actually installed.

The thing we say most

A room that never keeps up is nearly always airflow — a branch added when the basement was finished, a crushed flexible run, a damper closed years ago, or a return far too small.

An oversized replacement makes it slightly worse, and that is what usually gets sold.

Stated plainly

What this website will not tell you

Each one would be a number we invented.

Not statedWhy
A priceA schedule reset and a failed compressor are not the same visit. You get a fixed figure on the phone once we know what is installed.
A response timeWe will not promise two hours on a January morning when half the metro has no heat.
A saving“Cut your energy bill by a third” depends on the building, the hours and the tariff. It cannot be known from a web page.
A setback temperatureThe right overnight setting depends on the building, its contents and what it has to be ready for by morning. Anybody printing a number has not seen your building.
Questions

Asked often enough to answer here

The building is cold every Monday morning but fine by ten. Is something failing?

Usually not. The system is doing what it was told: set back over the weekend and started too late to bring a cold building up before the doors open. Check the start time on the controller against when people actually arrive, and check whether Monday starts earlier than the other days — it should, because the building has been cold for two days. It becomes a genuine fault when the building stops recovering by mid-morning, or when recovery gets slower month by month on the same settings.

Do you really tell people not to call you?

On six specific things, yes. An after-hours call-out that ends with somebody pressing a button on a controller is a bill nobody enjoys sending, and there is a page on this site listing the six we attend most often, what to check first, and exactly when each one genuinely is a fault. We would rather have the maintenance agreement and fewer of those visits.

Why do you record control schedules on an asset survey?

Because four of the six most common false-alarm call-outs start in a controller. Schedules get programmed once, by whoever installed the equipment, to the hours the building traded that year — and then trading hours change and the programme does not, because it belongs to nobody. Recording it is the cheapest line on the survey and it prevents the most visits.

What overnight setback should we use?

We will not put a number on a web page, and neither should anybody else. The right setting depends on the building, what is in it, and what it has to be ready for by morning — a warehouse, a clinic and a restaurant are three different answers. We will work it out with you once we have seen the building.

Does the altitude change how a gas appliance should be set up?

It can, and it depends on the model. Arvada is at roughly 5,300 ft and the input rating stamped on the plate is a sea-level figure. Some manufacturers require an orifice kit above a stated elevation, some specify a manifold pressure change, and some certify across a range with no change at all. It is in that model’s own installation instructions, so we read the model number and check.
