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

A heat pump works by transferring heat, not generating 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 cool your home by removing indoor heat, moving hot air outdoors to keep you cool.
In winter: they flip their function—pulling heat from the outside air and moving it inside. Yes, even when it’s cold out.

Benefits of Keeping Your Heat Pump Maintained

Heat pumps are among the most efficient ways to heat and cool a home. Maintenance isn’t just about avoiding breakdowns—it’s how you get the full value of what you’ve already invested in.

  • Lower Energy Bills: Dust buildup and clogged filters force your heat pump to use more energy to do the same job.
  • More Consistent Comfort: Strong airflow and better temp control start with regular heat pump maintenance.
  • Cleaner Indoor Air: Poorly maintained heat pumps can push contaminants into your home. Cleaning the system supports healthier 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: Well-maintained systems don’t just run better—they tend to last years longer.
  • Comfort When You Need It Most: Avoid sweating or freezing through an outage—routine heat pump maintenance in O’Fallon, MO, helps ensure comfort all year long.

Why Heat Pumps Need Bi-Annual Maintenance

Unlike a furnace or traditional air conditioner, a heat pump doesn’t get a season off. It operates through every season, even flipping between heating and cooling in transitional months.

For peak efficiency, manufacturers recommend twice-yearly tune-ups: once for heating, once for cooling. This gives us a chance to:

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

It’s not just about avoiding breakdowns—bi-annual service keeps your heat pump performing year-round.


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

No system is bulletproof—extreme weather in St. Louis can still cause problems, even with regular maintenance. Here are some common signs your heat pump may need service:

  • Weird noises: Strange sounds like rattles or hums might mean something’s come loose or electrical components are wearing out.
  • Uneven temperatures: If some rooms are too hot or too cold, your heat pump may not be distributing air properly.
  • Higher utility bills: A sudden spike often means the system is working harder than it should.
  • Short cycling: Systems that start and stop too often may be compensating for a hidden problem.
  • Weak airflow or ice buildup: Low airflow or visible ice usually means the system’s in trouble.

If you’re seeing—or hearing—any of these issues, now’s the time to schedule a O’Fallon, MO, heat pump maintenance check. We’ll help you stay ahead of any major system failures.


Heat Pump FAQs

Do heat pumps work in cold weather?

Yes—modern heat pumps are designed to operate efficiently even in freezing conditions. 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. They are two systems in one, and often more efficient than either.

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

Not only are they efficient, but many homeowners say heat pumps actually feel more comfortable—especially with advanced variable speed models.

Will a heat pump help me save energy?

Yes—transferring heat takes less energy than generating it, which makes heat pumps a smart, efficient choice. This lower energy use translates to cost savings and more consistent indoor temps.

But total energy use isn’t the whole story—rates matter, too. In Missouri, gas heat is usually less expensive—so an electric heat pump may not always mean a smaller bill. But if you’re replacing electric resistance heating, you’re likely to see noticeable savings.

Do heat pumps still need a furnace?

No—standalone heat pumps work great year-round in many O’Fallon, MO, homes. Dual-fuel systems are an option, but in most cases, one heat pump is enough to stay comfortable.
