What may be causing it

What usually causes these issues

Heating problems are often related to ignition components, airflow restrictions, electrical controls, or heat pump defrost and reversing valve issues.

A proper diagnostic identifies the exact cause before any repair is recommended, especially when similar symptoms can come from very different failures.

Repair vs replacement

We evaluate the system instead of guessing

If the system can be repaired reliably, we repair it. If frequent repairs, age, or overall condition suggest replacement may be the smarter long-term option, we explain both paths clearly so you can decide.
