Com+ Mechanical keeps climate-controlled storage at spec — temperature and humidity held within range across large, low-occupancy footprints in the five boroughs, Nassau, Westchester, northern New Jersey, and Stamford, CT. Protect tenant property, defend your "climate-controlled" rental promise, and avoid mold and condensation claims.
Most thermostats only manage temperature. On mild, damp days the cooling barely runs, so moisture is never wrung out and relative humidity climbs — exactly the condition that breeds mildew and musty odor inside 'climate-controlled' units. Dew-point and dedicated-dehumidification strategy, not just a setpoint, is what keeps tenant property dry.
Once a tenant opens a unit to find mildew on a couch or a moldy box, you're facing a damaged-goods claim, a refund, and a review that scares off prospects. The root cause is almost always sustained high humidity from undersized, poorly controlled, or neglected dehumidification — a maintainable, fixable problem when caught early.
Clogged drain pans, failed condensate pumps, and sweating ductwork put water on corridor floors and brown stains on ceilings near units. Beyond the slip and liability exposure, dripping water damages the very goods you're paid to protect. Routine condensate-line clearing and pan treatment prevents the calls.
Storage RTUs and split systems often each cover a large zone. When one fails in a July heat wave, an entire corridor of climate-controlled units climbs out of spec within hours — with no on-site staff watching gauges overnight or on weekends. Fast diagnosis, stocked common parts, and remote monitoring shrink the window before tenants are affected.
Many metro storage buildings run original RTUs well past their service life — short-cycling, leaking refrigerant, and burning energy across a very large footprint. Without a replacement plan, you get surprise capital failures at the worst time of year and an operating cost that quietly erodes per-square-foot margin.
A small problem goes unnoticed for days because there's no engineer walking the floor. By the time the district manager hears about it, humidity has been high long enough to cause damage. Scheduled PM visits plus remote temp/humidity alerts turn a silent drift into an early, low-cost fix.
A self-storage building is not an office. There are almost no people to cool — the job is holding temperature and, more critically, relative humidity across tens of thousands of square feet of corridors and locker banks, often over multiple floors and unconditioned drive-up sections. When humidity drifts up, tenants find mildew on furniture, rust on tools, warped documents, and musty-smelling boxes — and a "climate-controlled" unit that didn't deliver becomes a refund, a chargeback, or a damaged-goods dispute. In the NYC metro's humid summers and swing seasons, dew-point control is the whole game. Com+ Mechanical designs, services, and modernizes the packaged rooftop units, split DX systems, and dedicated dehumidification that storage buildings depend on, and we cover single sites and multi-property portfolios under one vendor so your district and area managers aren't chasing a different contractor at every location.
From call to comfort in 4 easy steps
We walk the building — RTUs, split systems, dehumidifiers, controls, condensate paths, and climate-controlled zones — and review temperature and humidity performance to find where you're at risk of drifting out of spec.
You get a clear scope: preventive maintenance tailored to storage, any repairs or retrofits the equipment needs, and recommended monitoring — with single-site or multi-site portfolio options and Custom Quote pricing.
We service RTUs, dehumidification, coils, and condensate on a planned cadence and watch temp/humidity remotely so issues surface early — minimizing visits that surprise you and keeping units dependably in range.
When a unit fails or humidity spikes, we diagnose fast, carry common parts, and prioritize the failures that threaten tenant property — then follow up with a repair-or-replace recommendation so the same problem doesn't recur.
The workhorse of most metro self-storage buildings — packaged DX rooftop units condition large corridor and locker zones, often with one unit per wing or floor section.
Purpose-built dehumidifiers (and reheat strategies) that manage moisture independent of temperature — the equipment that truly keeps 'climate-controlled' units dry on damp days.
Split air-conditioning systems serving offices, smaller climate-controlled sections, and conditioned staff areas within the facility.
We work on commercial systems — packaged rooftop units, split DX, and dedicated dehumidification — the equipment self-storage buildings actually run, not residential comfort gear.
We serve the five boroughs, Nassau, Westchester, northern New Jersey, and Stamford, CT — and we plan for this region's humid summers and damp swing seasons that drive storage humidity problems.
Operate multiple locations? One vendor, one point of contact, and consistent service standards across every facility — so your area and district managers aren't juggling separate contractors.
Our job is keeping units in spec so tenant property stays dry and undamaged — protecting your revenue, your reviews, and your climate-controlled promise.
No fees. No surprises. Just honest service.
Scheduled, storage-specific upkeep that keeps temperature and humidity in range and heads off the moisture problems that cause tenant claims.
From a failed compressor to end-of-life RTU changeouts, efficiency upgrades, and converting standard areas to climate-controlled.
Around-the-clock response for failures and humidity spikes that put tenant property at risk in an unstaffed building.
Pricing is scoped per facility based on equipment type and count, square footage, number of climate-controlled zones, and how many sites are covered. All engagements are Custom Quote.
Business+ plans start at $499/year — includes 2 rtu tune-ups, 10% off all services, and priority scheduling.

Yes — and for self-storage it's the priority. Holding temperature is straightforward; holding relative humidity in range is what actually protects tenant property and your climate-controlled promise. We service and tune dedicated dehumidification, verify reheat where applicable, and set controls to manage dew point so units don't develop mildew, musty odor, or condensation on mild, damp days when cooling barely runs.
Yes. We serve the five boroughs, Nassau, Westchester, northern New Jersey, and Stamford, CT, and we cover both single sites and multi-property portfolios under one vendor with a single point of contact and consistent service standards — so your area and district managers aren't coordinating a different contractor at every facility.
We offer 24/7 emergency service and prioritize failures that put tenant property at risk, with stocked common parts to speed restoration.
Two ways. Scheduled preventive maintenance visits catch wear — dirty coils, worn belts, clogging condensate lines — before they cause a failure. And optional remote temperature and humidity monitoring alerts us when a zone starts drifting out of range, so an overnight or weekend problem in an unstaffed building gets caught early instead of after tenant goods are damaged.
We'll give you a straight repair-vs-replace analysis. Many metro storage buildings run original RTUs past their service life, where they short-cycle, leak refrigerant, and waste energy across a very large footprint. We help you plan capital replacements on your timeline and budget cycle rather than getting forced into an emergency changeout during peak season.
Sustained high humidity (mildew, musty odor, rust, warped goods) and condensate problems (water on floors, ceiling stains, dripping near units) cause the most damaged-goods disputes — and both are preventable. Routine dehumidifier service, dew-point control, and condensate-line and drain-pan maintenance are the core of keeping units in spec and keeping claims off your desk.
