Ever feel like New Hampshire’s summer vanishes overnight? One day it’s shorts and t-shirts, the next you’re reaching for a sweater. This rapid temperature swing is more than just an inconvenience—it puts unique stress on your building’s most critical piece of equipment: the rooftop HVAC unit. Summer can disappear almost overnight, and by September, many buildings are already running heat in the mornings and cooling by afternoon. That swing makes early fall the ideal time to schedule a rooftop HVAC inspection.
Rooftop units (RTUs) carry a heavier workload than most systems. They not only cool through the summer and heat through the winter, but they also sit fully exposed to rain, sun, wind, and debris year-round.
Why Early Fall Timing Matters for RTUs
- Seasonal Changeover: September is when most buildings begin switching between cooling and heating. Testing both modes now ensures your system won’t fail when temperatures drop for good.
- Catch Summer Wear: After a long cooling season, belts, fans, and coils often show signs of stress. An inspection addresses that wear before you add heating demands.
- Stay Ahead of Emergencies: Service demand spikes as soon as the first cold mornings hit. Early fall inspection keeps you off the emergency list.
What Makes Rooftop Units Different?
- Exposure to Weather: Unlike indoor systems, RTUs take on heavy rain, temperature swings, and falling debris.
- Roof Conditions: Ponding water or roof leaks can drip into the unit and cause damage you won’t notice from inside.
- High Impact: A single RTU often serves multiple zones or even an entire building—failure means widespread disruption.
What’s Checked in an RTU Inspection?
- Clearing debris, leaves, and drain systems
- Checking panels, seals, and roof flashing for leaks
- Cleaning condenser and evaporator coils
- Testing both heating and cooling modes for smooth transition
- Inspecting electrical connections and safety controls
Signs to Schedule Now:
- Uneven cooling or heating between zones
- Strange noises or vibrations from the roof
- Water pooling near or under the unit
- Musty odors when the system cycles into heat mode
New Hampshire’s quick shift from summer to fall puts rooftop HVAC units under unique strain. An early fall inspection helps you stay ahead of failures, avoid costly downtime, and ensure a smooth seasonal transition.
