What We Do

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.

LL97 Note: Long Island City buildings over 25,000 sq ft face escalating carbon penalties starting 2024 — a threshold many LIC warehouses and larger loft conversions meet. A single-building owner doesn’t need a portfolio compliance program — just a consistent maintenance record showing the equipment has been properly serviced.

From walkthrough to worry-free coverage

One building, one contract, one year of coverage — here’s how we set it up.

01

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.

02

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.

03

Fixed-price proposal

You receive one clear annual number covering scheduled maintenance, with itemized detail on what’s included, before you sign anything.

04

Scheduled service & reporting

We show up on schedule, service your equipment to OEM specifications, and leave you a written report after every visit.

Questions we hear every day

Straight answers about a single-building maintenance contract in Long Island City — no marketing fluff.

Is this contract sized for a single building, or do I need a portfolio of properties?
This contract is built specifically for owner-operators running one Long Island City building — warehouse, loft conversion, or standalone commercial space. You won’t be quoted a portfolio-tier program; the scope, visit schedule, and price reflect exactly the equipment on your one roof.
What’s actually included in a Long Island City HVAC maintenance contract?
Every contract includes scheduled seasonal visits covering filter changes, refrigerant level checks, belt and bearing inspection, controls calibration, and a written report after each visit. Priority response for anything that breaks between visits is included as standard.
Does Denair service HVAC equipment in converted loft and warehouse buildings?
Yes — this describes a large share of Long Island City’s building stock. Converted lofts often run retrofitted VRF or split systems, while warehouses typically use heavy-duty packaged rooftop units. We’re factory-certified across both equipment categories.
How much does a commercial HVAC maintenance contract cost in Long Island City?
Pricing is based on your building’s equipment count and tonnage, determined during an on-site walkthrough — not a generic per-building rate. You’ll get one fixed annual number before you commit, so budgeting stays simple.
Does this contract help with Local Law 97 compliance?
Yes. Each scheduled visit includes an energy performance check, and your service history becomes a simple record you can provide to whoever prepares your LL97 filing — showing your equipment has been consistently maintained, which supports efficient operation.
