Installation
Installing new PTAC or water-source heat pump units in New York City requires careful coordination to ensure code compliance, building compatibility, and energy efficiency. The process typically involves removing the old equipment, verifying electrical and plumbing connections, upgrading sleeves or risers if necessary, and properly sealing the unit to prevent air and water infiltration. For PTACs, wall sleeve condition and amperage compatibility are key; for water-source heat pumps, verifying loop temperatures and flow rates is critical. All work must meet local DOB, fire, and noise codes, and often requires coordination with building management or co-op boards. Our team ensures a clean, efficient installation with minimal disruption to residents or tenants.

Retrofit and Replacement
Replacement and retrofit of PTACs or water-source heat pumps in NYC often involves more than just swapping out old units—it’s about ensuring long-term performance, compliance, and compatibility with existing infrastructure. Many older buildings have outdated sleeves, risers, or electrical setups that don’t meet the requirements of modern high-efficiency equipment. In these cases, retrofitting may include upgrading electrical circuits, or installing adapter kits to fit new units into legacy enclosures. We carefully assess each space to select equipment that matches capacity, voltage, and airflow needs, while minimizing disruption and avoiding unnecessary cosmetic damage. Our retrofit solutions are tailored to extend system life, improve comfort, and reduce energy costs—without compromising on DOB code compliance or tenant satisfaction.

Repair and Maintenance
Proper repair and maintenance of PTAC and water-source heat pump systems are essential to preserving efficiency, preventing breakdowns, and extending equipment lifespan—especially in the demanding climate and regulatory environment of New York City. Our service team specializes in diagnosing issues quickly, whether it's a compressor failure, water leak, thermostat problem, or poor airflow. We use OEM parts whenever possible and perform repairs to manufacturer standards while keeping disruption to tenants minimal. Regular maintenance—such as coil cleaning, filter changes, condensate pan flushing, and system performance checks—is crucial for avoiding emergency service calls and ensuring compliance with building and insurance requirements. We offer flexible maintenance plans customized to residential, and co-op properties, keeping systems running clean, quiet, and efficient year-round.

Preventative Maintenance
Preventative maintenance is the most effective way to protect your investment in PTAC and water-source heat pump systems, especially in NYC where equipment runs hard through both heating and cooling seasons. By scheduling routine inspections and servicing, we can catch small issues—like clogged filters, dirty coils, or minor leaks—before they lead to costly repairs or complete system failure. Our preventative maintenance plans include seasonal tune-ups, electrical and refrigerant checks, condensate pan and drain cleaning, and operational testing to ensure everything is running at peak efficiency. This not only reduces energy bills and extends equipment life, but also ensures compliance with local codes and building management standards. For co-ops, condos, and commercial properties, it’s a proactive strategy that minimizes tenant complaints and emergency downtime.

Sleeve maintenance and installation are critical components of any PTAC replacement or retrofit project, particularly in older NYC buildings where original wall sleeves may be rusted, warped, or improperly sealed. A damaged or poorly installed sleeve can lead to water intrusion, air leaks, pest entry, and inefficient system performance. Our team inspects all sleeves for structural integrity, drainage slope, and insulation quality before installing new units. When necessary, we replace sleeves with code-compliant models that are properly flashed, sealed, and pitched to drain outward, preventing long-term water damage to both the interior and building façade. Whether it’s a simple re-seal or full sleeve replacement, we ensure every installation is weather-tight, secure, and built to support the lifespan of your PTAC system.
