Why Heat Pumps Need Bi-Annual Maintenance

Most HVAC systems take a few months off. Heat pumps? They pull double duty all year. It works through all seasons, often switching modes based on shifting temperatures.

Getting service before both major seasons is the industry standard for heat pump care. This gives us a chance to:

  • Clear out dust and debris from coils and filters
  • Check refrigerant levels and pressures
  • Inspect electrical components
  • Calibrate the thermostat
  • Catch small issues early, before they affect performance or lead to a breakdown

Bi-annual maintenance doesn’t just prevent problems, it helps your system run better in every season.


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

St. Louis weather pushes HVAC systems hard, and even well-maintained heat pumps can run into issues. 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: Poor air distribution can lead to room-by-room comfort issues.
  • Higher utility bills: An overworked system drives up costs—especially if it’s straining to keep up.
  • Short cycling: Turning on and off repeatedly can signal airflow problems, low refrigerant, or sensor trouble.
  • Weak airflow or ice buildup: Low airflow or visible ice usually means the system’s in trouble.

Noticing any of these symptoms? It might be time for Lemay, MO, heat pump maintenance or a diagnostic. Catching it now means fewer surprises—and likely a smaller repair bill.


Heat Pump FAQs

Do heat pumps work in cold weather?

Absolutely—today’s heat pumps can handle cold weather without a problem. Systems with variable capacity often stay in heating mode even when it’s freezing out.

Is a heat pump just an air conditioner?

No—heat pumps handle both cooling and heating, depending on the season. 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?

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?

Yes—transferring heat takes less energy than generating it, which makes heat pumps a smart, efficient choice. That efficiency shows up in your utility bill—and in how comfortable your home stays.

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. 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?

Not necessarily. Many Lemay, MO, homes use all-electric heat pumps year-round. While some systems have backup heat (dual-fuel), a standalone unit is typically all you need.
