At first it didn’t even feel like a serious problem. HVAC was still on, just the air coming through the vents was unusually weak. Only after a couple of hours did it start to feel uncomfortable indoors, especially with the weather outside making things worse. From what I’ve seen in similar situations, restricted airflow often ends up being more than just a minor blockage, so it’s better not to ignore it for long. That’s where https://productairheating.com/heat-pump-emergency-repair/ helped a lot, since available 24/7 and the 4-hour response made it possible to get things checked quickly instead of waiting and hoping it fixes itself.
