Frequently Asked Questions
How much does HVAC installation cost?
HVAC installation costs range from $3,000 for basic systems to $18,000+ for premium units. The average installation costs $5,500. Factors include home size, efficiency rating, and ductwork needs.
How long does HVAC installation take?
Standard HVAC installation takes 4-8 hours for simple replacements. New installations with ductwork can take 1-3 days. Complex multi-zone systems may require up to a week.
What SEER rating should I choose?
Minimum SEER 14 is required in most areas. SEER 16-17 offers good efficiency/cost balance. SEER 18+ is premium efficiency for maximum energy savings in hot climates.
Do I need new ductwork with HVAC replacement?
Not always. Existing ductwork can often be reused if in good condition and properly sized. Duct cleaning, sealing, or modifications may be needed for optimal performance.
Are there rebates for high-efficiency HVAC systems?
Yes, many utility companies and government programs offer rebates for high-efficiency systems. ENERGY STAR units qualify for federal tax credits. Check local utility and manufacturer rebates.
How do I properly size an HVAC system for my home?
HVAC sizing requires professional load calculation based on square footage, insulation, windows, climate, and layout. Oversized units cycle frequently and waste energy. Undersized units can't maintain comfort. A Manual J calculation ensures proper sizing.
What's the difference between a heat pump and traditional HVAC?
Heat pumps provide both heating and cooling by moving heat rather than generating it, offering high efficiency in moderate climates. Traditional systems use separate AC and furnace. Heat pumps cost more upfront but save 30-40% on energy in suitable climates.
How often should HVAC systems be serviced?
Schedule professional maintenance twice yearly - spring for AC, fall for heating. Change filters monthly or quarterly. Annual tune-ups catch issues early, maintain efficiency, extend lifespan, and preserve warranties. Neglected systems fail sooner and cost more to operate.
