For over 40 years, Ultimate has delivered trusted, top-quality home service across the Denver Metro area — with NATE-certified technicians, fully stocked trucks, and honest, flat-rate pricing.
Our NATE-certified technicians diagnose, repair, maintain, and replace most makes and models — including Carrier, which we install as a Factory Authorized Dealer. Fully stocked trucks mean most heating problems get fixed on the spot.
No heat, short cycling, pilot issues, blower trouble — our techs arrive with the parts and diagnostics to fix most furnace problems in a single visit. Honest, flat-rate pricing. You'll only pay what you're quoted.
Reversing valve stuck, defrost cycle failing, auxiliary heat running constantly? We service and repair most major heat pump brands and walk you through every option before any work begins.
Free in-home estimates on system replacements. As a Carrier Factory Authorized Dealer, we install the most efficient HVAC systems on the market — no pressure, just options.
Wi-Fi thermostats, learning controls, multi-zone setups. We pair the right thermostat to your equipment and your home — and we make sure it works before we leave.
Whether it's a 20-year-old central system or a ductless mini-split in a finished basement, we diagnose airflow, refrigerant, and electrical issues quickly — and explain your options before starting any repair.
Not cooling, leaking, freezing up, or tripping the breaker? Our techs arrive with the tools, refrigerants, and parts to fix most central A/C problems on the first visit.
Ductless cooling for additions, bonus rooms, and zone-controlled homes. We service and repair single-zone and multi-zone systems, including head replacements and condenser diagnostics.
Free in-home estimates on replacement systems, complimentary second opinions, and 100% satisfaction guarantee. We install the most efficient HVAC systems on the market.
Whole-home humidifiers, dehumidifiers, and air quality assessments — installed and serviced by techs who understand exactly how Front Range air behaves season to season.
Whole-home assessments, filtration upgrades, and ventilation tuning. We identify the source of stale air, dust, and humidity issues — and recommend the right fix for your home.
Whole-home humidifiers integrated with your existing HVAC — no more dry skin, static, or cracked wood floors through a Denver winter. Installed and balanced in a single visit.
For basements, finished lower levels, and homes with chronic moisture issues. We size and install whole-home dehumidifiers that work in step with your A/C, not against it.
We hold an active Master Plumber License (03001760) and Plumbing Certification (0004792) — meaning every plumbing repair, maintenance call, or rough-in is performed under proper trade credentials, not a generalist with a wrench.
Tripping breakers, flickering lights, dead outlets, panel concerns — our electricians diagnose and repair home electrical issues quickly and safely, with the same flat-rate pricing and satisfaction guarantee as the rest of our trades.
Honest, flat-rate pricing means no surprises. Your technician explains every option before starting repairs, so you make informed decisions before any work begins.
