Emergency HVAC Service in Louisville, CO

When your heating or cooling system fails in Louisville, it isn’t just a matter of comfort—it’s a matter of home safety. At Ascent HVAC and Home Solutions, we provide 24/7 emergency HVAC repair in Louisville, CO, designed to handle the high-stakes climate of the North Denver Metro. From the newer, high-performance rebuilds in the Marshall Fire recovery areas to the established character of Old Town and Steel Ranch, we bring commercial-grade urgency to your residential mechanical emergency.

At 5,335 feet, a total furnace failure in January or a heat pump lockout in July can become a crisis within hours. Our technicians are local, highly trained, and equipped with the specialized tools needed to handle high-altitude combustion and the latest 2026 Colorado building mandates.

We don’t just “patch” a problem; we provide engineered repairs that restore your system to its peak safe operating condition.

As of January 1, 2026, Colorado law requires all newly manufactured gas-fired components to meet Ultra-Low NOx emissions standards. If your furnace fails, we ensure:

• Emergency Ignition Restoration: Fixing lockout issues caused by Erie/Louisville high-altitude air pressure.

• Safety & CO Sweeps: Every emergency visit includes a digital carbon monoxide check to ensure your heat exchanger hasn’t failed.

• Fire-Hardened Venting Repairs: We ensure your furnace intake and exhaust meet the City of Louisville’s specific 2026 Fire Hardening Code (1/8-inch metal mesh requirements) to prevent ember intrusion.

Heatwaves on the plains can be brutal. We specialize in the new A2L refrigerants and inverter technology found in modern Louisville homes.

• Hybrid System Troubleshooting: If your heat pump fails to “switch over” to its gas backup, we provide immediate recalibration.

• Capacitor & Inverter Board Replacement: We carry a “mobile parts lab” specifically stocked for the high-efficiency systems common in Boulder County.

If your emergency is related to a lingering environmental factor—such as ash-clogged blowers or soot-damaged sensors—we perform a deep-system audit. We repair and optimize your Indoor Air Quality (IAQ) suite to ensure the air you’re breathing is as safe as the temperature is comfortable.

Louisville has some of the most progressive building codes in the country. Our emergency services are fully compliant with:

1. 2024 ICC Standards: We follow the most recent International Code Council updates (effective late 2025/2026) for all mechanical repairs.

2. Louisville Fire Hardening Code: Even in an emergency, we don’t cut corners. We ensure exterior components (like vents and condenser shields) meet the town’s fire-resistance mandates.

3. Income-Qualified (IQ) Rebate Documentation: If your emergency repair turns into a replacement, we provide the documentation needed for Boulder County EnergySmart IQ rebates (up to $2,000 for qualified households).
