What Is a Heat Pump—and Why More Homeowners Are Using Them

A heat pump doesn’t create heat—it moves it. That simple difference makes it one of the most efficient and flexible ways to heat and cool a home. Learn more.

In summer: they work just like your AC, pulling heat from inside your home and sending it outside.
In winter: they reverse direction—drawing warmth from the air outside and bringing it in. Yes, even when it’s cold out.

Benefits of Keeping Your Heat Pump Maintained

Few systems match the efficiency of a heat pump when it comes to home comfort. If you want full value from your heat pump, routine maintenance is key.

  • Cleaner Indoor Air: Service isn’t just for efficiency—it also helps prevent your heat pump from spreading pollutants and improves your indoor air quality.
  • Fewer Repairs Over Time: Preventative maintenance often catches issues early—before they turn into costly repairs or mid-season failures.
  • Longer System Lifespan: When your system runs efficiently, it experiences less wear and tear over time—helping it last longer.
  • Comfort When You Need It Most: Nobody wants a breakdown during a heatwave or cold snap—timely St. Ann, MO, heat pump maintenance helps keep things running right.

Why Heat Pumps Need Bi-Annual Maintenance

Unlike a furnace or traditional air conditioner, a heat pump doesn’t get a season off. It keeps your home comfortable all year, even as the seasons shift and outdoor temps swing.

Manufacturers recommend twice-yearly maintenance—once for the cooling season and once for the heating season—for optimal performance. This gives us a chance to:

  • Replace filters and clean the coils
  • Verify proper refrigerant charge and system pressure
  • Look over wiring, fuses, and capacitors
  • Verify accurate thermostat readings
  • Identify potential issues before they impact efficiency or cause a failure

Regular maintenance twice a year helps your system run stronger, longer—no matter the season.


What to Watch For: Signs Your Heat Pump Might Need Service

Routine service helps, but your system can still run into trouble—especially during peak summer or winter in St. Louis. Here are some common signs your heat pump may need service:

  • Weird noises: New or loud noises often mean your system needs a closer look.
  • Uneven temperatures: Uneven temps usually mean the heat pump isn’t working as evenly as it should.
  • Higher utility bills: A sudden spike often means the system is working harder than it should.
  • Short cycling: If your system keeps cycling, it’s likely struggling with efficiency or control issues.
  • Weak airflow or ice buildup: Restricted flow or icing is often caused by clogs, leaks, or failing parts.

Heat Pump FAQs

Do heat pumps work in cold weather?

Yes—modern heat pumps are designed to operate efficiently even in freezing conditions. Variable capacity systems, in particular, can maintain comfort in below-freezing temperatures without switching to backup heat.

Is a heat pump just an air conditioner?

Not at all—heat pumps cool in summer and heat in winter by reversing their operation. They are two systems in one, and often more efficient than either.

Does switching to a heat pump mean I’ll lose comfort?

No—they’re often more comfortable than older systems, with consistent airflow and better humidity control from variable-speed operation.

Will a heat pump help me save energy?

Yes—they save energy by moving heat instead of producing it like a traditional furnace or baseboard system. That efficiency shows up in your utility bill—and in how comfortable your home stays.

But total energy use isn’t the whole story—rates matter, too. In Missouri, gas is often cheaper than electricity—so switching from a gas furnace to a heat pump could raise your bill, even with better efficiency. On the other hand, swapping out electric resistance heat should reduce your monthly bill.

Do heat pumps still need a furnace?

Nope. In St. Ann, MO, plenty of homes rely solely on electric heat pumps for heating and cooling. Some systems do include a backup furnace—known as dual-fuel—but most houses don’t need one.
