Performance & Energy Use

When you switch from a gas furnace to a heat pump, your energy costs shift between utilities.

What to Expect

• Gas usage will drop significantly (often close to zero for heating)
• Electricity usage will increase, especially during winter
• Your winter electric bill may be higher than you’re used to

This is normal. Your heat pump now uses electricity to move heat instead of burning gas to create it. Longer heating cycles in cold weather increase electricity use, but this does not mean your system is inefficient or malfunctioning.

Look at Total Energy Costs

It’s important to compare your total combined gas + electricity costs over the full year, not just one winter month. Many homeowners see:

• Lower total annual energy costs
• Reduced emissions
• More consistent indoor comfort

Heat pumps operate more slowly than traditional gas furnaces or air conditioners, especially when raising or lowering temperatures significantly.

While setting your thermostat back when you’re away or at night can save energy, dramatic changes often force the system to run continuously on higher power to recover, wiping out the savings or even using more energy overall.

Keep your thermostat fan speed on Auto for the best balance between comfort, noise, and energy performance.

• Auto: Adjusts airflow automatically for efficiency, while preferring lower speeds.
• Low / Medium / High: Runs at your selected speed during heating or cooling. Jetson may temporarily adjust the fan to maintain performance and efficiency.
• Fan Only: Circulates air without heating or cooling

Small improvements can significantly reduce system strain and energy use:

• Replace or clean air filters regularly
• Seal drafts and improve insulation
• Use ceiling fans to improve comfort in warm weather

Clogged filters and air leaks increase workload and energy consumption.
