Emergency HVAC Service in Lafayette, CO

In a town where the weather can swing from a sunny afternoon at Waneka Lake to a sub-zero “Blue Norther” windstorm in hours, a broken HVAC system isn’t just an inconvenience—it’s an emergency. At Ascent HVAC and Home Solutions, we provide 24/7 emergency HVAC repair in Lafayette, CO, to ensure your home remains a safe haven regardless of the conditions outside. We bring commercial-grade urgency and technical precision to every crisis call, serving neighborhoods from the historic bungalows of Old Town to the modern estates in Indian Peaks and Coal Creek Village.

When your furnace locks out in January or your AC fails during a July heatwave, you don’t have time for a “nine-to-five” contractor. Our local technicians are stationed in the North Denver Metro, ready to be at your doorstep with a fully stocked “mobile parts lab” to fix the issue on the first visit. We prioritize safety and speed, ensuring that a mechanical failure doesn’t lead to frozen pipes or dangerous indoor temperatures.

Not every glitch requires an emergency dispatch, but certain symptoms indicate your home’s safety or system’s integrity is at risk. Call us immediately if you experience:

• Total Heating Loss in Freezing Weather: If your furnace or heat pump won’t turn on when temperatures are below 32°F, your home can reach dangerous levels quickly.

• Gas Odors (Rotten Eggs): If you smell gas, evacuate immediately, call Xcel Energy, and then contact us for a professional repair of your system’s combustion components.

• Electrical Smells or Smoke: A burning plastic odor often signals melting wires or a failing capacitor—both are significant fire hazards.

• Loud Grinding or Banging Sounds: These often indicate a failing blower motor or a loose component that could cause catastrophic damage if the system continues to run.

• AC Failure During Extreme Heat: For households with seniors, infants, or medical needs, a lack of cooling during a 90°F+ day is a medical priority.

Lafayette’s 5,236-foot elevation means your HVAC system operates under different physical laws than a sea-level unit. Emergency repairs in the Front Range require a specialized touch.

In Lafayette’s thinner air, furnaces often face “ignition lockout” where the system fails to strike a flame or stay lit. Our emergency technicians use digital combustion analyzers to recalibrate your system on the spot, ensuring safe, reliable ignition even in the middle of a blizzard.

Lafayette is frequently hit by high-velocity winds that can blow out pilot lights on older units or force debris into outdoor condensers. Our emergency repairs don’t just fix the part; we check for “wind-resilience,” ensuring your system is better prepared for the next storm.

Even in a crisis, we adhere to the 2026 City of Lafayette safety and energy standards. We ensure every emergency part replacement is compatible with modern efficiency mandates, protecting your home’s value and your safety.
