What We Do
Complete HVAC Services
From emergency repairs to full system design, we handle every aspect of your home's comfort.
AC Repair & Installation
R32 and R-410A refrigerant systems, 1.5–5 ton capacity. AHRI-certified sizing with Manual J load calculations. We don’t guess — we calculate.
Furnace Service & Replacement
80% and 96% efficiency models, 40k–120k BTU. Proper sizing prevents short-cycling, cold spots, and wasted energy. PVC and metal vent options.
Heat Pump Systems
Energy-efficient heating and cooling in one unit. Modern cold-climate heat pumps work great in Utah down to -15°F. Dual-fuel hybrid options available.
Full System Replacement
Matched AC + furnace systems designed as a unit. We run Manual J sizing and Manual D ductwork design so everything works together optimally.
Ductwork Design & Repair
Static pressure testing, leak sealing, and balanced airflow to every room. Poor ductwork is the #1 cause of hot/cold spots — not your equipment.
Indoor Air Quality
MERV 13 media filtration, whole-home humidifiers, ERVs, UV-C germicidal lights, and HEPA air purifiers. Breathe cleaner air in every room.
Our Method
Design Before Equipment
This is how ACCA, ASHRAE, and ENERGY STAR say every HVAC job should be done. Most contractors skip steps 1 and 2.
Calculate (Manual J)
We calculate your exact heating and cooling load based on your home's insulation, windows, orientation, square footage, and Utah's climate zone. No guessing, no rules of thumb.
Design (Manual D)
We design your ductwork to deliver the correct volume of air to every room. This eliminates hot/cold spots and ensures proper humidity control and efficiency.
Verify (Testing)
After every install, we measure refrigerant charge, airflow, static pressure, and temperature delta. If anything is off, we fix it before we leave.
