Our Reznor Make-Up Air Unit Repair Services in Long Island City
Emergency repair, preventative maintenance, and replacement — keeping Reznor make-up air units running through Long Island City's demanding heating season.
Emergency Reznor MAU Repair
A failed Reznor unit means cold air pouring into your LIC building or kitchen fast. We reach your site typically within 4 hours, stocked with genuine Reznor parts.
Burner & Ignition System Service
Full diagnostic and repair of Reznor's gas-fired burner and ignition components — the most common point of failure in commercial MAU systems.
Reznor Preventative Maintenance
Custom maintenance plans starting from $396/year, timed ahead of Long Island City's heating season to catch burner, belt, and blower issues before they cause downtime.
Belt & Blower Replacement
Worn belts and blower motors are diagnosed and replaced with correctly sized OEM-equivalent parts, restoring proper airflow volume.
Reznor Replacement & Retrofits
When repair no longer makes economic sense, we handle full Reznor unit replacement — sizing, DOB filings where required, and startup commissioning included.
LL97 Compliance Optimization
NYC's Local Law 97 targets buildings over 25,000 sq ft — a growing share of Long Island City's industrial and mixed-use stock. We assess your Reznor system's carbon exposure.
From cold air to back online
One partner handles every step. Here's how we do it.

You call, we respond. A certified technician reaches your Long Island City location within 4 hours — equipped with diagnostic tools and common Reznor parts to resolve most issues on the first visit.
Root cause diagnosis
We check the burner, ignition, blower, and controls together — identifying the actual point of failure rather than a quick patch that fails again in the cold.
Fixed-price proposal
Before a wrench turns, you receive a clear, itemized quote with no hidden line items. What we quote is what you pay.
Certified repair & commissioning
Factory-trained technicians execute the repair to Reznor's OEM specifications, then verify airflow and burner performance before we leave the roof.
