Heating Not Reaching All Rooms – Las Vegas HVAC Diagnostic

We were called out to troubleshoot a heating issue in a Las Vegas home where the master bedroom was the only area staying warm. The rest of the house wasn’t getting proper airflow, and the system was running continuously without reaching the thermostat setting. After a thorough diagnostic, we discovered multiple airflow issues that were causing the imbalance.

What We Found

We arrived at the Las Vegas home after the homeowner reported that only the master bedroom was getting heat while the rest of the house remained cold. After performing a complete system diagnostic, we confirmed that the heating system was turning on and all components were running, including the outdoor unit and indoor blower motor. However, airflow was very poor throughout the home—especially in the family room, where there was no airflow at all.

Upon inspection, we found two major issues: a completely clogged filter at the base of the furnace inside the attic and a section of disconnected ductwork caused by a broken duct collar. Additionally, return filters in the hallway were dirty, further contributing to restricted airflow.

How We Fixed It

We removed the clogged base filter, which immediately improved airflow throughout the system. Next, we reattached a new collar to the supply plenum and securely resealed the ductwork to restore airflow to the family room. We also checked that temperatures were rising properly and set the thermostat to 70°F to monitor performance.

🚀 The Result

With the airflow issues resolved and ductwork restored, the home now receives balanced heat in every room. The system is operating efficiently, and the thermostat is reaching its set temperature without continuous running. Comfort has been restored throughout the home.
