Convair Gas Heater Repairs FAQ
This is one of the most common issues we see. Causes can include no ignition, blocked filters, airflow restrictions, sensor faults, or electrical issues. A proper diagnostic assessment is required to identify the exact cause and avoid unnecessary part replacement.
Reverse cycle systems can fail to heat due to refrigerant issues, outdoor unit faults, sensor errors, or control problems. In some cases, systems may also enter defrost mode, which can be mistaken for a fault. We can diagnose whether it’s a normal function or a repair issue.
Flashing lights or error codes indicate that the system has detected a fault. While these codes can help point technicians in the right direction, they do not always identify the exact failed component. Proper testing is still required to confirm the issue.
This depends on the age of the system, parts availability, overall condition, and repair cost. We take a repair-first approach and will always provide honest advice if a system is no longer economical to repair.
Yes. We diagnose and repair ducted systems in both residential and commercial applications, including airflow issues, electronic component faults, control PCB problems, and breakdowns.
Yes, we work on selected high-efficiency gas heating systems. These systems are more complex and require accurate diagnosis, particularly when dealing with communication faults and modulating gas valves.
For residential systems, we recommend servicing every 1–2 years. For commercial systems, more frequent servicing (every 3–6 months) may be required depending on usage. Regular servicing helps prevent breakdowns and maintains efficiency.
Water leaks are usually caused by blocked condensate drains or incorrect installation. This should be addressed quickly to prevent damage to ceilings, walls, or flooring.
