Rooftop HVAC Unit Installations: Common Problems and Expert Solutions

Rooftop HVAC Unit Installations in NYC: Common Problems and Expert Solutions

Your Guide from SIB AIR, Manhattan’s Trusted HVAC Specialists

In Manhattan, space is always at a premium. That’s why many commercial buildings, apartment complexes, and mixed-use properties rely on rooftop HVAC units. These systems save valuable indoor space, provide efficient climate control, and are designed to meet the demands of New York’s unique architecture.

But rooftop HVAC units face challenges of their own. Exposure to the elements, heavy workloads, and complex installation requirements mean they need proper care and expertise. At SIB AIR, we’ve installed, repaired, and maintained rooftop units across the city. Here’s a guide to common issues and when to call in the professionals.

Common Rooftop HVAC Problems and How to Handle Them

1. Uneven Heating or Cooling in the Building

Why it happens: Improper installation, duct leaks, or blocked airflow.

What you can try: Check indoor vents and thermostats for obstructions or incorrect settings.

When to call SIB AIR: If comfort issues persist, your rooftop system may need balancing, sealing, or capacity adjustments.

2. Strange Noises from the Rooftop Unit

Why it happens: Loose components, worn belts, or debris caught in fans.

What you can try: Replace air filters and visually inspect outdoor areas if safely accessible.

When to call SIB AIR: Grinding, banging, or screeching noises mean mechanical parts are failing and should be repaired immediately.

3. Unit Fails to Start or Shuts Off Unexpectedly

Why it happens: Electrical issues, thermostat failures, or safety switches tripping.

What you can try: Check breakers, confirm thermostat settings, and reset the system.

When to call SIB AIR: If the system won’t restart, our technicians can run a full diagnostic and fix the underlying problem.

4. Reduced Efficiency or Weak Airflow

Why it happens: Dirty coils, clogged filters, or low refrigerant levels.

What you can try: Clean or replace filters regularly and schedule preventive maintenance.

When to call SIB AIR: If airflow or efficiency doesn’t improve, professional cleaning or refrigerant service is required.

5. Leaks or Water Pooling Around the Unit

Why it happens: Blocked condensate drains or weather damage.

What you can try: Power down the system and look for visible drainage issues if safe.

When to call SIB AIR: Water near electrical components is a serious risk. Our team will clear drains, check seals, and ensure the unit is secure.

Quick Rooftop HVAC Care Checklist

Do this regularly:

  • Replace or clean filters every 1–3 months
  • Schedule biannual maintenance before peak seasons
  • Keep rooftop access clear and safe for technicians
  • Inspect surrounding areas for debris or weather damage
  • Monitor energy bills for sudden increases

Avoid these mistakes:

  • Don’t delay service when the unit shows signs of wear

  • Avoid ignoring loud or unusual noises
  • Don’t overload the system by neglecting regular cleaning
  • Never attempt DIY refrigerant handling
