Frequently Asked Questions
How Often Should I Service My HVAC System? For optimal performance and longevity, your HVAC system should generally be serviced at least once a year, but the specifics depend on the type of system and your usage
Can You Perform Warranty Service On A Unit You Didn’t Install? In most cases, HVAC contractors can perform warranty work even if they didn’t install the unit, but there are some caveats: Manufacturer Warranty: The warranty is typically tied to the unit itself, not the installer. As long as the system is under warranty, any licensed HVAC technician can usually do repairs or service. Installer-Specific Requirements: Some warranties require the original installer to perform certain services or submit claims. Check the warranty paperwork for phrases like “authorized dealer” or “installation required by licensed contractor.” Proof of Warranty: You may need to provide the original purchase receipt or registration information to the manufacturer. Third-Party Service: Many HVAC companies will service units they didn’t install, but sometimes the manufacturer might require them to submit work through an authorized network. There may be limitations on covering labor costs if it’s not the original installer. ✅ Bottom line: You usually can get warranty service from another licensed HVAC company, but always check the manufacturer’s warranty terms to avoid surprises.
How Often Should I Change My Filter? Standard air filters: every 1–3 months depending on usage, pets, and indoor air quality. HEPA or higher-efficiency filters may last longer but should still be checked monthly.
