In Flemington, NJ, a repair was conducted on a Carrier Infinity Series HVAC unit experiencing uneven heating and cooling distribution. The diagnostic revealed a faulty thermostat and a clogged air filter, which were significantly impacting the system's performance. The thermostat was replaced with an updated, programmable model for better temperature control, and the air filter was swapped for a high-efficiency particulate air (HEPA) filter to improve airflow and air quality. Post-repair testing confirmed restored efficiency and balanced temperature distribution throughout the property.
