A heat pump doesn’t generate heat—it transfers it. That simple difference makes it one of the most efficient and flexible ways to heat and cool a home.
In summer: they act like an air conditioner, pulling heat from inside your home and sending it outside.
In winter: they reverse direction—pulling heat from the outside air and moving it inside. Yes, even when it’s cold out.
No combustion, no fuel, no separate AC and furnace. Just one system that does it all, with fewer moving parts and lower energy use.
Because heat pumps both heat and cool your home, many St. Louis homeowners are replacing their aging HVAC systems with one high-efficiency unit. Models like the Daikin FIT are quiet, compact, energy-efficient, and eligible for rebates—especially when installed by a trusted local HVAC and heat pump contractor like SmartHouse.
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.

Unlike a furnace or traditional air conditioner, a heat pump doesn’t get a season off. 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:
Bi-annual maintenance doesn’t just prevent problems, it helps your system run better in every season.
Even with regular maintenance, problems can still crop up—especially when your system’s working overtime during extreme St. Louis weather. Here are some common signs your heat pump may need service:
If you’re seeing—or hearing—any of these issues, now’s the time to schedule a tune-up or diagnostic. The sooner we take a look, the easier it is to head off major repairs.
Yes—modern heat pumps are designed to operate efficiently even in freezing conditions. Variable capacity systems, in particular, can maintain comfort in below-freezing temperatures without switching to backup heat.
No—a heat pump can cool your home like an air conditioner in the summer, but it can also reverse direction to heat your home in the winter. They are two systems in one, and often more efficient than either.
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.
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 means they use significantly less energy than traditional electric resistance heating, and often outperform older systems in both comfort and efficiency.
That said, energy costs can vary. In Missouri, electricity tends to cost more than natural gas—so if you’re switching from gas heat to an all-electric heat pump, your utility bill might go up even though you’re using less total energy. If you’re replacing an electric furnace or baseboard heat, though, you’ll likely see lower electric bills.
Not necessarily. Many St. Louis homes use all-electric heat pumps year-round. Some setups include a backup furnace (called dual-fuel), but for most homes, a standalone heat pump is enough to stay comfortable in all seasons.
