Furnace Repair in Phoenix, AZ FAQs

What is the most common furnace failure?

The most common furnace problem usually comes from a malfunctioning ignition system or pilot light. When your furnace won’t start, it’s often because the ignition can’t light the burners properly. Other frequent issues include dirty filters, worn-out blower motors, or thermostat problems. Regular maintenance and timely repairs can help prevent failures and keep your furnace running efficiently throughout the winter.

What brand of furnace is the most reliable?

Rather than focusing on a specific brand, the most reliable furnace is one that’s properly installed, maintained, and repaired. Even a high-quality furnace can underperform if it isn’t installed or maintained correctly, so pairing your system with professional service is key. SemperFi keeps your furnace running efficiently by handling expert installation, performing regular maintenance, and addressing repairs promptly, ensuring your home stays warm regardless of the brand.

How long do furnaces last in Arizona?

With proper care and maintenance, a typical furnace in Arizona can last 15 to 30 years. Several factors influence its lifespan. The quality of installation is crucial; poorly sized or improperly installed systems can strain components and reduce efficiency. Additionally, the size of the system matters. Oversized units tend to short-cycle frequently, while undersized units run constantly, both of which can cause extra wear and tear.

Maintenance schedules also play a major role. Regular inspections, cleaning, and tune-ups can add 5 to 10 years to a furnace’s life. Additionally, how you use your furnace can impact its longevity. Keeping thermostat settings within a moderate range will prevent unnecessary strain and help your system last longer.
