Why Heat Pumps Need Bi-Annual Maintenance

There’s no off-season for heat pumps—they heat, cool, and adjust constantly based on the weather. 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:

  • Clear out dust and debris from coils and filters
  • Test and confirm refrigerant balance
  • Check electrical connections and safety controls
  • Calibrate the thermostat
  • Catch small issues early, before they affect performance or lead to a breakdown

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

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: 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: Turning on and off repeatedly can signal airflow problems, low refrigerant, or sensor trouble.
  • Weak airflow or ice buildup: Frozen coils and weak output usually point to trouble behind the scenes.

Strange noises or weak airflow? Schedule your St. Charles, MO, heat pump maintenance before it gets worse. We’ll help you stay ahead of any major system failures.


Heat Pump FAQs

Do heat pumps work in cold weather?

Definitely—modern heat pumps are built to keep working even in sub-freezing temps. Variable-speed systems are especially good at staying efficient in below-freezing weather—no need for backup heat.

Is a heat pump just an air conditioner?

No—unlike a traditional AC, a heat pump also provides heat in cold weather. This combo of cooling and heating often outperforms separate systems in both roles.

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

Not at all. In fact, many homeowners find heat pumps more comfortable thanks to steadier airflow and better humidity control—especially with variable speed technology that avoids the blast-and-coast cycle of older systems.

Will a heat pump help me save energy?

Yes. Heat pumps are one of the most energy-efficient ways to heat and cool a home because they move heat instead of generating it. That efficiency shows up in your utility bill—and in how comfortable your home stays.

Still, what you pay depends on local utility rates. In Missouri, gas heat is usually less expensive—so an electric heat pump may not always mean a smaller bill. If your old system was all-electric, a heat pump can bring serious efficiency improvements.

Do heat pumps still need a furnace?

Not necessarily. Many St. Charles, 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.
