One straightforward
maintenance contract
for your Long Island City
building — nothing more
Built for owner-operators running a single Long Island City warehouse, loft, or commercial building who want one clear annual agreement — not a portfolio-sized program with add-ons you’ll never use. Fixed scope, fixed price, one point of contact.

What’s Included in Your Long Island City Maintenance Contract
A single, right-sized agreement for a single building — no portfolio tiers, no bundled units you don’t operate.
Straightforward Contract Scoping
We walk your Long Island City building once, price your actual equipment — warehouse RTU, loft-building VRF, or a mix — and write one contract, not a tiered portfolio program.
Scheduled Seasonal Tune-Ups
Spring and fall visits cover filters, refrigerant levels, belts, bearings, and controls calibration — timed to NYC’s cooling and heating seasons so your system is ready before demand hits.
Priority Repair Response
Contract customers move ahead of standard service calls. If something breaks between scheduled visits, you get faster on-site response than a one-off service call would get.
One Point of Contact
The same team that scoped your contract handles your visits and any repair calls — no call center, no rotating technicians who don’t know your equipment.
LL97 Compliance Tracking
Each visit includes an energy performance check, building a simple ongoing record you can hand to your accountant or filing preparer ahead of LL97 deadlines.
Fixed Annual Pricing
One number, agreed up front, covers your full year of scheduled maintenance. Any repair work outside the agreement is quoted and approved before we start.
From walkthrough to worry-free coverage
One building, one contract, one year of coverage — here’s how we set it up.
On-site walkthrough
A certified technician visits your Long Island City building once to document the equipment you actually operate — whether that’s a warehouse RTU or loft-building VRF system.
Right-sized contract terms
We write a contract scoped to your single building’s equipment and visit needs — not a multi-property template with coverage you’d never use.
Fixed-price proposal
You receive one clear annual number covering scheduled maintenance, with itemized detail on what’s included, before you sign anything.
Scheduled service & reporting
We show up on schedule, service your equipment to OEM specifications, and leave you a written report after every visit.
