Cold bedrooms do not always mean the furnace is failing. Closed dampers, blocked return vents, leaky ducts, poor insulation, or an unbalanced system can all create temperature differences. Furniture placed over registers may also limit circulation. Finding the airflow issue is often the key to improving comfort. Call (303) 798-3880 to schedule an HVAC inspection and find out what may be affecting airflow. https://littletonair.com/

A sudden drop may be related to a leak or pressure issue, while readings that climb too high can point to an expansion tank or valve problem. Since boiler designs vary, the correct operating range is not universal. Call (303) 798-3880 to discuss your boiler concerns. https://littletonair.com/
