Book Your Fall Furnace Tune-Up Before Denver's First Freeze
September 25 is National Tune-Up Day, the industry-recognized reminder that Denver homeowners should book their annual fall furnace tune-up before winter demand hits. Call 360 HVAC Pro at (720) 925-2051 to schedule.
Here's why annual furnace tune-ups matter more in Denver than in mild climates: our heating season runs October through April (a full six months), Commerce City sits at 5,150 feet where altitude affects gas combustion, and Denver's dry air plus cottonwood and construction dust clog filters and coils faster. All of that means a fall tune-up catches worn ignitors, dirty flame sensors, weak capacitors, and combustion issues before they become a no-heat emergency on the coldest night of the year.
Both the CDC and ENERGY STAR recommend annual furnace inspection for safety and efficiency. Skipping it can void manufacturer warranties, raise heating bills by 10 to 15 percent, and create real carbon monoxide risk from combustion issues that go undetected.
Our $189/year Maintenance Plan covers your fall furnace tune-up plus spring AC tune-up, priority scheduling, member repair discount, 24/7 emergency service, and written summaries for warranty documentation. No contracts. No auto-renewal traps. No inflated pricing.
