Residential HVAC (H01)
HVAC systems keep Utah homes comfortable through temperature extremes – but proper sizing, installation, and maintenance determine efficiency and lifespan.
This BidScope guides you through HVAC system types: forced air (furnace + AC most common in Utah), heat pumps (heating and cooling in one unit, efficient in moderate climates), ductless mini-splits (no ductwork, zone control), and radiant heating covered separately.
Learn heating options: gas furnaces (95%+ AFUE efficiency standard now, reliable in Utah cold), electric furnaces (100% efficient but expensive to operate, backup heat for heat pumps), and heat pump heating (efficient above 30°F, needs backup below).
Understand cooling: central AC (matched to furnace, SEER ratings 14-25), heat pump cooling (same unit heats and cools), proper refrigerant (R-410A phasing out, R-32 newer).
Master sizing: Manual J load calculation required for proper sizing, oversized systems short-cycle and waste energy, undersized systems can’t maintain temperature, Utah factors (altitude affects capacity, temperature extremes, home insulation levels).
Navigate ductwork: proper design prevents hot/cold rooms, duct sealing and insulation critical, return air adequacy, zoning for multi-story or large homes.
Learn efficiency ratings: AFUE for furnaces (95%+ for high-efficiency), SEER for cooling (higher = more efficient but diminishing returns), HSPF for heat pump heating.
Understand installation quality: proper refrigerant charge critical, airflow verification (350-450 CFM per ton typical), combustion analysis for gas furnaces, ductwork sealing.
Know maintenance: annual tune-ups extend life, filter changes (monthly during peak use), cleaning coils.
Navigate replacement decisions: age (15-20 years typical life), efficiency of old versus new, repair costs approaching replacement.
Calculate incentives: Utah energy rebates for high-efficiency, federal tax credits.
Budget realistically: furnace replacement $3,000-6,000, AC $3,500-7,000, heat pump $5,000-9,000, full system $6,000-12,000+.
This tool ensures your HVAC system is properly sized, installed, and maintained for comfort and efficiency.
