When your rooftop unit fails, your entire building feels it — whether it is a commercial property on Queens Boulevard, a mixed-use building in Rego Park, or a residential complex right here in Forest Hills. You need a certified HVAC team that understands rooftop systems, responds fast, and gets the job done right the first time.
Our technicians are fully certified on all major RTU brands. We handle everything from emergency compressor failures and refrigerant leaks to full rooftop unit replacements and new RTU installations. With years of experience serving Queens buildings and businesses, we understand the structural, mechanical, and code requirements unique to New York City rooftop HVAC systems.
Rooftop unit failures do not follow business hours. We dispatch RTU-certified technicians day and night, including weekends and holidays, throughout Forest Hills and all of Queens.
You receive a clear, flat-rate quote before any work begins. No hidden fees, no surprise charges on your final invoice. Every time.
We do not just answer the phone — we show up. Most Forest Hills RTU calls are handled the same day, often within 1 to 2 hours of your call.
We know Forest Hills inside and out. From the commercial corridors along Queens Boulevard and Continental Avenue to the apartment buildings and retail strips throughout Rego Park, Kew Gardens, and Middle Village.
RTU not heating or cooling? Compressor locked up? Controls failing? We diagnose and repair all rooftop unit makes and models on the first visit. Our technicians arrive fully stocked with common RTU parts so we can resolve most issues the same day without a return trip. Queens summers are brutal and Forest Hills winters are punishing — we make sure your rooftop system keeps up with both.
Planning a new RTU installation for your commercial building, retail space, restaurant, or multi-unit property in Forest Hills? We handle the full scope — from load calculations and equipment selection to crane coordination, curb installation, electrical connections, and startup commissioning. Every installation is done to NYC DOB code with full permit documentation.
Older RTU beyond economical repair? We remove your existing unit and install a new energy-efficient replacement with minimal disruption to your building's operations. We work around your schedule and handle all permits, inspections, and disposal of the old equipment.
The best way to avoid a mid-season rooftop unit failure is a consistent maintenance program. We offer scheduled semi-annual tune-ups — one before cooling season and one before heating season — to keep your RTU running at peak efficiency and catch small problems before they turn into expensive repairs.
System failed completely in the middle of the night? Call us immediately. We prioritize emergency RTU calls throughout Forest Hills and all of Queens, seven days a week, 365 days a year. Our goal is to arrive within 1 to 2 hours for urgent calls.
Sometimes the rooftop unit itself is fine — the problem is in the controls, zone sensors, or building automation interface. We diagnose smart thermostats, DDC controls, zone dampers, and wiring faults on all RTU control systems.

Not sure what is wrong with your RTU? Here are the most frequent issues we resolve every day across Forest Hills and Queens:
The most urgent RTU failure. Could be a seized compressor, a blown capacitor, a tripped breaker, a failed contactor, or an ignition fault on gas-fired units. We diagnose the root cause on the first visit and fix it the same day in most cases.
Low refrigerant means your RTU cannot cool properly and will cause compressor damage if left unchecked. We locate the leak, repair it, and recharge the system to manufacturer specifications. All our technicians are EPA 608 certified for refrigerant handling.
A clogged filter, dirty evaporator coil, failed blower motor, or collapsed duct connection at the RTU curb can completely destroy your airflow. We find the exact cause and restore full air distribution fast.
Compressor failure is one of the most serious and most common RTU problems in buildings that skip regular maintenance. We assess whether compressor replacement or full unit replacement is the more cost-effective path — and give you an honest recommendation either way.
Gas-fired rooftop units develop cracked heat exchangers and ignition failures over time, especially in units exposed to Queens weather year-round. We inspect, repair, or replace heat exchangers and ignition systems and ensure your RTU passes any required NYC inspections.
Unit turning on and off every few minutes? Short cycling strains every component of your rooftop unit and dramatically shortens its lifespan while spiking your energy bills. We find the root cause — whether it is an oversized unit, a refrigerant issue, a dirty coil, or a failed sensor — and fix it correctly.
A sudden jump in your Con Edison bill often means your rooftop unit is working far harder than it should. We tune your RTU back to rated efficiency, identify what is causing the waste, and recommend upgrades where they deliver real payback.
Rooftop units in Forest Hills and across Queens endure some of the harshest operating conditions in the country — intense summer heat and humidity followed by deep winter freezes, combined with constant rooftop exposure to wind, debris, and UV. Without consistent maintenance, even a quality RTU will fail years ahead of its expected service life.
Our RTU maintenance service includes a full safety and code inspection, cleaning of evaporator and condenser coils, filter replacement, lubrication of all moving parts, refrigerant level check, electrical connection tightening, belt and pulley inspection, burner assembly cleaning on gas units, thermostat and controls calibration, and a complete written performance report.
For emergency calls we typically arrive within 1 to 2 hours anywhere in Forest Hills and the surrounding Queens neighborhoods, day or night. We keep technicians stationed locally so response times are fast and consistent.

We provide a clear flat-rate quote before any work begins so there are no surprises.

RTU sizing depends on your building's square footage, ceiling height, insulation, sun exposure, and internal heat loads from occupants and equipment. Our technicians perform a proper Manual J load calculation before recommending any unit so you get the right size — not oversized, not undersized — for maximum efficiency and long-term performance.
Do not wait while your building gets hotter or colder by the hour. Our team is standing by right now.
