What is the 2026 Furnace Rule in Colorado?
Starting January 2026, Colorado requires new furnaces to meet Ultra-Low NOx or Energy Star 5.0 standards. While replacing your current furnace isn’t mandatory, regular professional servicing is crucial to ensure older units operate safely and efficiently.
When is the best time for a furnace tune-up?
We suggest scheduling your furnace tune-up in early fall. This timing allows us to address any potential issues before the cold winter months set in, ensuring your system runs smoothly.
How long does a furnace service appointment take?
A comprehensive furnace service appointment typically lasts between 60 to 90 minutes. After the inspection, we provide a detailed report of our findings and any recommended actions.
Can I perform furnace maintenance myself?
While changing your air filter every 30–90 days is advisable, full furnace maintenance should be left to professionals. It involves handling high-voltage electricity and natural gas, which requires expertise for safety and warranty purposes.
Why is annual furnace service important?
Annual furnace service is essential for safety, efficiency, and compliance. It helps prevent carbon monoxide leaks, reduces utility bills, and ensures your system meets Colorado’s emission standards.
