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 act like an air conditioner, moving hot air outdoors to keep you cool.
In winter: they switch modes—capturing outdoor heat—even in cold weather—and transferring it indoors. Yes, even when it’s cold out.

Benefits of Keeping Your Heat Pump Maintained

One of the most efficient home comfort solutions? A heat pump. Skipping maintenance means leaving efficiency—and money—on the table.

  • Lower Energy Bills: When airflow is blocked by dust or gunk, your heat pump burns more energy to keep up.
  • More Consistent Comfort: Routine service keeps airflow strong and temperature control accurate.
  • Cleaner Indoor Air: When your system’s dirty, so is the air you breathe. Routine service helps protect your indoor air quality.
  • Fewer Repairs Over Time: Catching small problems early can save you from big repairs later on.
  • Longer System Lifespan: Maintenance helps reduce strain on components, extending the life of your heat pump.
  • Comfort When You Need It Most: Scheduling heat pump maintenance in Affton, MO, before summer or winter hits helps prevent breakdowns when you need your system most.

Why Heat Pumps Need Bi-Annual Maintenance

A furnace hibernates in summer. An air conditioner takes winters off. A heat pump keeps going no matter the season. It runs when it’s hot, it runs when it’s cold—and in the spring and fall, it may switch between heating and cooling depending on the weather.

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
  • Check electrical connections and safety controls
  • Test and adjust the thermostat
  • Catch small issues early, before they affect performance or lead to a breakdown

Twice-a-year maintenance keeps your system efficient and reliable, season after season.


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

Your heat pump works hard through St. Louis extremes, and sometimes things go wrong—even with regular care. Here are some common signs your heat pump may need service:

  • Weird noises: Grinding, buzzing, or rattling can point to loose parts or electrical issues.
  • Uneven temperatures: Temperature swings between rooms may signal a circulation problem.
  • Higher utility bills: When bills go up unexpectedly, your system may be losing efficiency.
  • Short cycling: Frequent starts and stops often mean there’s a deeper issue—like a bad sensor or blocked airflow.
  • Weak airflow or ice buildup: When airflow slows or ice appears, something’s definitely not working right.

Think something’s off? Now’s a good time to book Affton, MO, heat pump maintenance and catch it early. Catching it now means fewer surprises—and likely a smaller repair bill.


Heat Pump FAQs

Do heat pumps work in cold weather?

Yes—most modern systems perform well even when temperatures drop below freezing. Variable systems can modulate output and keep your home warm without kicking over to auxiliary 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. You get year-round comfort in one efficient package.

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

Nope. With steadier temperatures and better humidity control, heat pumps—especially variable-speed ones—can feel more comfortable than conventional systems.

Will a heat pump help me save energy?

Definitely. By moving heat rather than creating it, heat pumps operate with impressive energy efficiency. They use far less energy than electric baseboard heat or outdated HVAC setups—and they often feel more comfortable, too.

But total energy use isn’t the whole story—rates matter, too. Switching from gas to electric in Missouri can sometimes increase monthly costs, even with better system performance. If you’re replacing an electric furnace or baseboard heat, though, you’ll likely see lower electric bills.

Do heat pumps still need a furnace?

Actually, most Affton, MO, homes don’t need a backup system—their heat pumps handle all four seasons. While some systems have backup heat (dual-fuel), a standalone unit is typically all you need.
