Why Heat Pumps Need Bi-Annual Maintenance

A standard furnace rests in summer. An AC gets the winter off. Your heat pump? It works year-round. It runs in both summer and winter—and in spring or fall, it might switch modes day to day.

Want optimal performance? Schedule heat pump maintenance twice a year: once before summer, once before winter. This gives us a chance to:

  • Clean coils and filters
  • Test and confirm refrigerant balance
  • Inspect electrical components
  • Test and adjust the thermostat
  • Identify potential issues before they impact efficiency or cause a failure

With service in spring and fall, your system stays ready for whatever the weather brings.


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: Grinding, buzzing, or rattling can point to loose parts or electrical issues.
  • Uneven temperatures: Inconsistent temps are often a sign your system needs service.
  • Higher utility bills: If your energy bills jump, your heat pump may need a tune-up.
  • 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: Restricted flow or icing is often caused by clogs, leaks, or failing parts.

Noticing any of these symptoms? It might be time for St. Peters, MO, heat pump maintenance or a diagnostic. Quick action now can help avoid bigger problems later.


Heat Pump FAQs

Do heat pumps work in cold weather?

Modern heat pumps? They’re built to stay efficient even in freezing weather. 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?

No—heat pumps do double duty, keeping you cool in summer and warm in winter. It’s a single system that does both jobs—often more efficiently than standalone units.

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

Far from it—today’s heat pumps often deliver a more even, comfortable indoor climate than older AC and furnace setups.

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. They use far less energy than electric baseboard heat or outdated HVAC setups—and they often feel more comfortable, too.

That’s the catch: energy savings depend on how your home’s powered. In Missouri, gas heat is usually less expensive—so an electric heat pump may not always mean a smaller bill. On the other hand, swapping out electric resistance heat should reduce your monthly bill.

Do heat pumps still need a furnace?

No—standalone heat pumps work great year-round in many St. Peters, MO, homes. You can pair it with a furnace, but most setups stay efficient and cozy without one.
