Total Climate Control. Engineered for Colorado.
From high-efficiency residential installs to complex commercial HVAC systems, ICS designs, installs, and maintains heating and cooling solutions built for Colorado's extreme temperature swings — with the same flat-rate transparency and master-certified expertise we bring to every trade.
What We Do
Full-Service HVAC for Colorado
From a single-family furnace replacement to a multi-building commercial HVAC system, ICS has the NATE-certified technicians, equipment, and engineering capability to handle it all.
HVAC System Installation
Full design and installation of residential and commercial heating and cooling systems — sized correctly for your space, load, and Colorado climate.
Furnace Repair & Replacement
Gas, electric, and heat pump furnace diagnostics, repair, and full replacement. We work on all major brands and carry common parts on every truck.
Air Conditioning Service
Central AC, mini-split, and commercial chiller service — from refrigerant recharge and coil cleaning to full system replacement.
Commercial HVAC Systems
RTU installation and service, VAV systems, chilled water plants, and custom commercial mechanical design for office, retail, industrial, and multi-family.
Ductwork Design & Installation
Properly designed ductwork is the foundation of HVAC efficiency. We design, fabricate, and install sheet metal and flex duct systems for new construction and retrofits.
Indoor Air Quality
HEPA filtration, UV air purifiers, ERV/HRV ventilation, and humidity control systems — because Colorado's dry climate and wildfire smoke demand more than a standard filter.
Preventive Maintenance
Scheduled maintenance agreements keep your system running at peak efficiency, extend equipment life, and catch problems before they become emergencies.
Emergency HVAC Response
No heat in a Colorado winter or no AC during a summer heat wave is an emergency. ICS responds 24/7 with fully stocked service trucks.
ICS HVAC in Action
Commercial & Residential HVAC — Installed Right the First Time
Colorado's climate demands HVAC systems that can handle 100°F summers and sub-zero winters without skipping a beat. ICS engineers and installs systems built for that reality — with the load calculations, quality equipment, and professional commissioning that make the difference between a system that lasts 20 years and one that fails in five.
How It Works
The ICS HVAC Installation Process
Every ICS HVAC installation follows a rigorous engineering-first process — from load calculation through commissioning. No guesswork, no oversizing, no shortcuts.
Load Calculation & Design
Manual J load calculations ensure your system is sized correctly — not oversized (which causes humidity problems) or undersized (which causes comfort failures).
Equipment Selection
We specify equipment matched to your load, budget, and efficiency goals — from standard 14 SEER units to 20+ SEER variable-speed systems.
Ductwork Assessment
Existing ductwork is tested for leakage and flow. We repair, seal, or redesign as needed — because even the best equipment underperforms in a leaky duct system.
Professional Installation
Factory-trained technicians install your system to manufacturer specs, local code, and ACCA quality installation standards — with full permits pulled.
System Commissioning
Every installation is commissioned: airflow balanced, refrigerant charged to spec, controls programmed, and performance verified against design targets.
Ongoing Maintenance
We offer maintenance agreements that include annual tune-ups, filter changes, coil cleaning, and priority emergency response — keeping your system at peak performance.
Why Choose ICS
HVAC Done Right — Engineered for Colorado's Climate
Colorado's climate is uniquely demanding — 300 days of sunshine, sub-zero winter nights, and summer temperatures that push 100°F. HVAC systems here need to perform at both extremes, and they need to do it efficiently. That requires proper load calculations, quality equipment, and installation that follows the engineering — not just the fastest path to completion.
ICS brings NATE-certified technicians, Manual J load calculations, and a commitment to permitted, inspected work on every installation. We don't cut corners that show up as comfort problems, high utility bills, or failed inspections at resale. We do it right the first time — and we back it with our unconditional satisfaction guarantee.

The Credentials That Protect Your Investment
HVAC certification isn't just a credential — it's the difference between a system that performs for 20 years and one that fails in five. ICS holds the certifications that matter.
NATE Certification
North American Technician Excellence (NATE) certification is the industry's highest standard. Our technicians test and maintain current NATE credentials.
EPA 608 Certified
All refrigerant handling is performed by EPA Section 608 certified technicians — required by federal law and essential for proper system performance.
Permitted Work Only
Every installation requiring a permit gets one — no exceptions. Unpermitted HVAC work voids manufacturer warranties and creates liability at resale.
Carbon Monoxide Safety
Every furnace service includes combustion analysis and CO testing. We don't leave a gas appliance running without verifying it's safe.
Ready for a System That Actually Performs?
Whether you need emergency service, a new installation, or a maintenance agreement, ICS has the certified technicians and equipment to get it done right.
