Fall Tune Up Part 14 – Reading the Numbers

Imagine waking up on a chilly Dallas morning only to find your home isn’t heating up as it should. This is exactly what happened during our recent Fall Tune Up when we checked the air temperature being supplied and returned by the furnace. Homeowners need to pay attention to these numbers, as they can reveal underlying issues that might lead to costly repairs or uncomfortable living conditions.

As we measured the temperature coming out of the vents, we found an average of 105 degrees. However, the return air temperature was hovering around 80 degrees, which raised a red flag. A furnace typically should achieve a temperature rise between 35 to 65 degrees. With a reading of just 29 degrees, we knew there was something to investigate further. Fortunately, a lower temperature rise can often indicate that there are no major airflow issues, which is a relief for any homeowner.

What’s the takeaway? Regular HVAC maintenance is crucial to ensure your heating system operates efficiently. During our tune-up, we identified the need for a little more runtime to optimize performance, but nothing alarming came to light. As a trusted HVAC provider in Dallas, we recommend scheduling seasonal maintenance to keep your system in top shape, ensuring your home stays warm and cozy throughout the colder months.
