Q1: What Is a Heat Pump?A heat pump is an HVAC system that heats and cools your home by moving heat instead of generating it.
How It Works

1. Absorbs heat from the outside air (even when cold)
   
2. Transfers heat indoors during winter
   
3. Reverses operation in summer to cool the home
   
4. Uses refrigerant to move heat efficiently
   

Benefit: One system for both heating and cooling.

Q2: What Is a Central AC Unit?A central air conditioner only cools your home by removing heat from indoor air and releasing it outside.
Key Points

1. Works with your existing furnace or air handler
   
2. Cannot provide heating unless paired with a furnace
   
3. Circulates cooled air via ductwork
   
4. Uses refrigerant and a compressor to remove heat
   

Q4: When Should You Choose a Heat Pump Over AC?Ideal Scenarios

1. Mild to moderate winters (San Mateo climate)
   
2. Want one system for heating and cooling
   
3. Energy efficiency is a priority
   
4. Avoid fossil fuels with electric heat pumps
   
5. Small to medium-sized homes without existing ductwork
   

Q5: When Should You Choose a Central AC?Ideal Scenarios

1. Already have a furnace for heating
   
2. Only need cooling system
   
3. Short-term budget constraints
   
4. Large homes requiring robust cooling
   
5. Areas with very cold winters (heat pump efficiency drops in extreme cold)
   

Q6: How Do Heat Pumps Save Energy Compared to AC + Furnace?

1. Moves heat rather than creating it
   
2. Uses 1/3 to 1/2 less electricity for heating
   
3. Avoids fossil fuel combustion in electric models
   
4. Reduces overall seasonal energy costs
   
5. Works well in mild coastal climates like San Mateo
   

Q7: Are Heat Pumps More Expensive to Install?Yes — upfront costs are higher than central AC because they combine heating and cooling components.
Cost Considerations

• Average heat pump: $5,000–$10,000 (depending on size & brand)
  
• Central AC + furnace: $4,000–$9,000
  
• Long-term energy savings often offset initial investment
  

Q8: Do Heat Pumps Work in Cold Weather?Modern cold-climate heat pumps can operate efficiently down to 25–30°F.
Considerations

1. Supplemental heat may be needed in extreme cold
   
2. Efficiency drops below 20°F
   
3. San Mateo’s mild winters make heat pumps ideal
   

Q9: Maintenance Differences Between Heat Pumps and AC

1. Heat Pumps: Seasonal inspection for both heating & cooling
   
2. AC Units: Annual check-up for cooling only
   
3. Both require:
   
   • Coil cleaning
     
   • Refrigerant checks
     
   • Air filter replacement
     
   • Electrical safety inspection
     

Q10: Which Is Right for My San Mateo Home?

• Heat Pump: Best for mild winters, energy efficiency, and all-in-one heating/cooling
  
• AC Unit: Best if paired with furnace for heat or when only cooling is needed
