How a Heat Pump Works
A heat pump moves heat instead of creating it with a flame. In summer it pulls heat out of your house like an air conditioner; in winter it reverses and pulls heat from outdoor air into the home. That one outdoor unit — plus an indoor coil or air handler — is why many Laurel County homes can heat and cool with a single system.

What is a heat pump, in plain English?
Inside the refrigerant loop, a compressor, outdoor coil, expansion device, and indoor coil move heat energy. A reversing valve flips which coil acts as the condenser. You still need properly sized ductwork (or a ductless head for a mini-split) and a correctly charged system — the physics only works when the install matches the load.
When is a heat pump the right fit for Laurel County?
Heat pumps shine in mixed climates like Laurel County: humid summers, cool-to-cold winters, and shoulder seasons where you need both modes. They are a strong fit for all-electric homes, efficient replacements for aging AC + electric furnace pairs, and hybrid (dual-fuel) packages that keep a gas furnace for the coldest nights.
What heat-pump problems do homeowners notice first?
Ice on the outdoor unit in heating mode can be normal during a defrost cycle — but constant ice, warm air in cooling, or short-cycling usually means airflow, charge, or controls need a technician. Undersized equipment and leaky ducts make even a good heat pump feel weak.
What has Leo Jones & Son learned installing heat pumps in Southeastern Kentucky?
Leo Jones & Son has installed and serviced heat pumps across London and Laurel County for decades, with factory-trained technicians on the equipment we install and all major brands serviced. We size to Manual J-style load reality — not a rule-of-thumb square-footage guess — because Kentucky humidity and house construction vary street to street.
How do you get a heat pump matched to your London-area home?
If you are evaluating a new heat pump or your current unit is struggling, schedule a Comfort Consultant visit. We will walk the home, check ducts and electrical, and recommend heat pump only, dual-fuel, or a conventional split based on how you actually live in the house.
What do Laurel County homeowners actually feel from a heat pump?
On humid July afternoons around London and Corbin, a correctly charged heat pump should pull moisture while it cools — sticky upstairs rooms usually point to airflow, duct leaks, or short cycling rather than the heat pump idea being wrong. In January, brief cool supply air during defrost is normal; rooms that never recover after a freeze night usually need a dual-fuel conversation or a service check on outdoor fans and filters. Our Comfort Consultants start with those symptoms because Southeastern Kentucky weather stacks humidity and wet freezes in the same week more often than brochure climates admit.

Frequently asked questions about how a heat pump works in London and Laurel County
Should I read this or just call for a heat pump that is not heating?
If the house is unsafe or you have no heat on a freezing night, call (606) 864-6105 for emergency service until 10:00 PM. Use this guide when you want to understand how the system is supposed to work before a scheduled diagnosis or replacement conversation.
Does a heat pump work when it is freezing outside?
Modern cold-climate and dual-fuel systems are designed for Kentucky winters. Output drops as outdoor temperature falls, which is why many Laurel County installs pair a heat pump with a gas furnace for the coldest nights.
Is a heat pump the same as a mini-split?
A mini-split is a type of heat pump (usually ductless). Central heat pumps use your duct system; mini-splits serve one or more rooms with wall or ceiling heads — common for additions and cabins.
Can you service a heat pump that another company installed?
Yes. We service all makes and models from our London shop, and we can evaluate whether repair or replacement is the honest next step.
Do heat pumps need ducts?
Central heat pumps use ducts; ductless mini-splits do not. Laurel County additions and cabins often use mini-splits when ducts are impractical.
Should I replace my AC and furnace with one heat pump?
Often yes for efficiency, sometimes with dual-fuel gas backup for the coldest nights. We size after seeing your London-area home — not from square footage alone.
