Frequently Asked Questions

Both furnace maintenance and furnace repairs are important aspects of keeping your furnace running its best. They are different, however. Furnace maintenance is more of a tune-up that ensures your furnace is running efficiently and reliably. Furnace repairs are more focused and resolve a specific issue or problem.

Your furnace needs a maintenance appointment once a year to run its best. At your annual furnace maintenance appointment, our technicians will evaluate your furnace to catch any issues and make any necessary tune-ups. A well-maintained furnace will run more efficiently and be less likely to experience a breakdown.

Higher-end and lower-end furnaces all require regular maintenance at least once a year. A higher-end model will run better between maintenance services than a lower-end model, but any unit will run at its best with regular maintenance from a certified technician.

Without regular furnace maintenance, your furnace unit is more likely to need an unexpected repair. In the same way a regular physical from a doctor keeps you healthy, regular furnace maintenance keeps your furnace healthy. It’s an opportunity to catch any smaller repairs before they turn into bigger issues and to keep your furnace running well.
