How a Heat Pump Works (and Why It Fits West Texas)
It's an air conditioner that can run in reverse — one system that both heats and cools, and a great fit for mild Permian Basin winters.
Heat Pumps & Mini-Splits
A heat pump is an air conditioner that can run in reverse. In summer it moves heat out of your home like any AC; in winter it moves heat into your home. Because it moves heat instead of burning fuel, it's very efficient in mild West Texas winters.
If you already understand how central AC works, you already understand most of a heat pump — it's the same refrigeration cycle with one clever addition.
How does one system both heat and cool?
The refrigeration cycle moves heat in one direction. A heat pump adds a reversing valve that flips the direction of the refrigerant:
- Summer: it pulls heat from inside and dumps it outside (cooling) — exactly like an AC.
- Winter: it reverses, pulling heat from the outdoor air (yes, even cool air holds heat) and releasing it inside (heating).
One outdoor unit, one indoor unit, both jobs.
Why do heat pumps fit West Texas so well?
Heat pumps are most efficient in mild weather — and Odessa and Midland winters are mostly mild. For the large majority of our heating season, a heat pump warms your home using a fraction of the energy of electric resistance heat, while doing double duty as your air conditioner through our long, brutal cooling season.
What about a hard freeze?
On the rare deep freeze — like February 2021 — a heat pump's efficiency drops as it gets very cold outside. That's why many local homes pair a heat pump with backup heat: either electric strip heat or a gas furnace (a "dual-fuel" system) that takes over on the coldest nights. You get efficient heating almost all winter and a safety net when it counts.
Where it goes wrong
- No backup plan. In our climate a heat pump should have a backup heat strategy for the rare freeze.
- Bad sizing. Like any system, it must be sized with a load calculation, not a guess.
- Expecting furnace-like blast heat. Heat pumps deliver steady, gentle warmth rather than the hot blast of a gas furnace — comfortable, but different.
What we see in the field
More Permian Basin homeowners are choosing heat pumps once they realize our mild winter is exactly the condition that makes them shine — efficient heating and cooling from one system. When a home needs guaranteed high-output heat, we'll talk through dual-fuel honestly.

Frequently asked questions
How does a heat pump heat a home in winter? +
A heat pump uses a reversing valve to run its refrigeration cycle backward. Even cool outdoor air holds heat, and the heat pump extracts that heat and moves it inside. Because it moves heat rather than burning fuel, it's very efficient in mild weather.
Do heat pumps work in a West Texas winter? +
Yes, for the large majority of our mild winter they heat efficiently. On a rare hard freeze their output drops, which is why many homes pair a heat pump with electric or gas backup heat (a dual-fuel system) for the coldest nights.
Is a heat pump the same as a mini-split? +
A ductless mini-split is a type of heat pump — it just delivers the air through wall or ceiling heads instead of ductwork. Central heat pumps use your existing ducts. Both heat and cool using the same reverse-cycle principle.
