Changed, with sizes and quantities recorded on the unit as well as on the sheet, so a set can be ordered without a trip to the roof.

Rooftop plant in a city that buries it
Shops, professional suites, clinics, restaurants and small industrial units across Syracuse and Onondaga County — maintained on a schedule, with a written record for every unit.
Maintenance
A record per unit, not a tick against the site. A sheet saying “serviced” is worth very little the day something fails.
Every visit
Every visit
Coils
Both faces inspected and cleaned, condition graded, pressure drop noted so the trend is visible rather than remembered.
Every visit
Belts and bearings
Tension and alignment set, part numbers listed, worn sheaves flagged rather than quietly re-belted year after year.
Every visit
Electrical
Contactors, capacitors and terminals. Pitting makes heat and heat makes more pitting, and eventually a compressor starts through a bad connection.
Before winter
Combustion
Burners, heat exchangers, flues and safeties on gas and oil plant. September, not December, and not on the first cold Monday.
Seasonal
Economisers
Dampers driven through their range, linkage and actuator checked, minimum outside-air position recorded as a number. The most commonly skipped item there is.
What snow does to a commercial roof
The equipment is the same as anywhere. The conditions are not.
Access is the first problem. A roof with two feet of snow on it is a different job from the same roof in September, and it is a safety question before it is a scheduling one. Which is why the annual visit belongs in autumn.
Intakes and exhausts get buried. Outside-air intakes, flue terminations and relief openings all sit at roof level, and roof level moves. A unit drawing combustion air through a snowbank behaves badly long before it stops.
Drifting is not uniform. Snow piles against parapets, behind curbs and on the lee side of every unit, which is precisely where the access panels are.
Condensate freezes. Drains and traps on rooftop plant run through the coldest air there is. Where they freeze, water backs up into the unit.
None of this is exotic. It is simply the difference between a maintenance contract written for this city and one written for somewhere else.
Drifting collects on the lee side of every unit, which is where the access panels are.
Premises, and what we will not promise
What we look after
- Retail and trade counters — door heat losses in a seven-month winter
- Restaurants and bars — extract against make-up air, which is where most dining-room complaints come from
- Professional suites and clinics — zone complaints, after-hours running, outside-air rates written down
- Small industrial units — unit heaters, extract and the ventilation that matters more than the cooling
What we will not put in a contract
- A guaranteed response time in hours. We will tell you where you are in the queue and call back. A printed number gets broken in a lake-effect event, which is exactly when you would be relying on it
- A percentage off your energy bill. Real savings exist and depend on your tariff, hours and building. The figure comes after the survey
- Work that belongs to another trade. Roofing, structure, snow clearance, hood cleaning and fire suppression. We photograph what we find and tell you who to call
