How to Know If You Have a Heat Pump (and Why It Matters)
The simplest way to check: go to your thermostat on a cold day and set it to heating mode. Then go outside and watch the outdoor unit. If the outdoor unit is running during heating, the fan is spinning, the compressor is operating, you have a heat pump. A traditional gas furnace system shuts the outdoor unit off entirely in winter; the outdoor component only runs for air conditioning.
You can also check for an “emergency heat” or “aux heat” setting on your thermostat. That option only exists on heat pump systems. The auxiliary heat is a backup electric resistance heat strip (or in dual-fuel systems, a gas furnace) that supplements the heat pump when outdoor temperatures drop low enough that the heat pump’s efficiency decreases.
Why it matters for service: heat pumps have components and operating characteristics that central AC systems don’t, reversing valves, defrost cycles, auxiliary heat sequencing, balance point calculations. A technician who treats a heat pump like a central air conditioner will miss things that matter.
Heat Pump Repair in Morehead, KY — What Problems Actually Look Like
Heat pump problems often present differently than furnace or AC problems, and some things that appear to be problems are actually normal operation. Here is an honest guide to common issues and what they typically mean:
The system is blowing lukewarm air in heating mode — is this a problem?
Not necessarily. Heat pumps produce supply air in the 90–105°F range, compared to a gas furnace which produces 120–140°F. If you put your hand over a heat pump supply vent in January, the air will feel warm but not hot. This is normal and does not indicate a problem, the system is designed to run longer at lower temperatures rather than shorter blasts of very hot air.
If the air genuinely feels cool or room temperature during heating, that’s different. That could indicate low refrigerant, a reversing valve problem, or a failing compressor, and warrants a service call.
The outdoor unit is covered in frost or ice in winter.
A light frost on the outdoor unit during cold weather is completely normal. Heat pumps have a built-in defrost cycle that periodically reverses operation to melt accumulated frost, you’ll notice the auxiliary heat kicks on briefly during defrost, and steam may appear to rise from the outdoor unit as the ice melts. This is normal.
What is not normal: a solid block of ice covering the outdoor unit for hours at a time, or a unit that never seems to clear its defrost cycle. That can indicate a refrigerant issue, a defrost control board problem, or an airflow restriction.
The system runs constantly and the home doesn’t reach the set temperature.
On the coldest days in Morehead, below 30°F and particularly below 25°F, a heat pump running continuously without reaching the set temperature may be operating at the edge of its efficiency range. This is a design characteristic, not necessarily a malfunction. The auxiliary heat should be staging on to compensate.
If this happens on mild days (40s and 50s), there is likely a performance problem, low refrigerant, a dirty coil, or a compressor that’s losing capacity.
The “auxiliary heat” or “emergency heat” light is on constantly.
Auxiliary heat is designed to supplement the heat pump when the heat pump alone can’t maintain temperature. It’s normal for aux heat to run occasionally on cold days. If it’s running constantly regardless of outdoor temperature, the heat pump is likely not functioning properly and is handing off full heating duty to the backup, which is expensive to operate and a signal something is wrong.
Reversing valve failure
The reversing valve is the component unique to heat pumps that switches the refrigerant direction between heating and cooling modes. When it fails, the system may be stuck in one mode, cooling when you need heat, or heating when you need cooling. Reversing valve replacement is a specialized repair that requires a technician with heat pump experience.
Refrigerant issues
Like central AC systems, heat pumps can develop refrigerant leaks. Unlike central AC, a heat pump with low refrigerant affects both heating and cooling performance. The symptoms in heating mode are often subtler than in cooling mode, which is why heat pump refrigerant problems sometimes go undiagnosed for longer than they should.

As with any HVAC repair, the cost of a specific repair relative to the age and condition of the overall system determines whether repair or replacement is the right financial decision. We’ll always give you an honest assessment rather than a reflexive recommendation in either direction.
New Heat Pump Installation in Morehead, KY — Is a Heat Pump Right for Your Home?
Heat pumps have become significantly more capable and efficient over the past decade, and they are a genuinely excellent choice for many Morehead homes. They’re not the right choice for every situation. Here is an objective breakdown:
Heat pumps work well for Morehead homes when: The home is well-insulated and has reasonably tight construction. The heating load is moderate, most of the heating season falls in the 30–50°F range rather than sustained deep freezes. The homeowner values energy efficiency and is willing to accept a higher upfront cost in exchange for lower operating costs. The home currently uses electric resistance heat (baseboard or wall heaters), in which case a heat pump will dramatically reduce heating costs. The home doesn’t have existing gas service and adding it would be costly.
A dual-fuel system (heat pump + gas furnace backup) is often the best of both worlds: In Rowan County’s climate, a dual-fuel system, a heat pump that handles most of the heating season efficiently, paired with a gas furnace that takes over when outdoor temperatures drop below the heat pump’s efficient operating range, gives you the efficiency of a heat pump in moderate temperatures and the reliable high-output heat of a gas furnace in the coldest weeks of the year. For homes that already have gas service, this setup is increasingly popular and for good reason.
Heat pumps are less ideal when: The home has significant infiltration or insulation issues that haven’t been addressed. The existing ductwork is inadequate for the system’s airflow requirements. The homeowner primarily wants the simplest, lowest-cost system to install (a standard gas furnace is less expensive upfront in that scenario).
Heat Pump Installation Cost in Morehead, KY
| System Type | Installed Cost Range |
|---|---|
| Air-source heat pump (replacement, existing ductwork) | $4,500 – $9,000 |
| Dual-fuel system (heat pump + gas furnace) | $7,000 – $14,000 |
| Cold-climate heat pump (high-efficiency) | $6,000 – $12,000 |
| Heat pump with new air handler | $5,500 – $11,000 |

Frequently Asked Questions — Heat Pump Service in Morehead, KY
My heat pump is making a sound like a helicopter or a loud whoosh in winter. Should I be worried?
Probably not. The defrost cycle causes the reversing valve to switch direction, which produces a fairly loud whooshing or swooshing sound. This is normal operation. If you also notice the outdoor fan stopping and the system appearing to reverse briefly, that’s the defrost cycle. Normal. If the loud sound is a grinding, clanking, or metal-on-metal noise, that’s different, call us.
At what outdoor temperature should my heat pump stop being the primary heat source?
This depends on the specific heat pump model and its rated efficiency curve. Most conventional heat pumps lose significant efficiency below 35–40°F. Modern cold-climate heat pumps maintain efficient operation considerably lower. If you have a dual-fuel system, the gas furnace typically takes over somewhere between 25°F and 40°F depending on how the balance point is set. We can check your system’s settings and advise whether the balance point is calibrated correctly for your equipment.
Can I add a heat pump to my existing central air system?
In some cases, yes, replacing just the outdoor AC unit with a heat pump outdoor unit and adding an appropriate air handler. Whether this is feasible depends on the compatibility of your existing indoor equipment, ductwork capacity, and electrical service. It’s worth evaluating before assuming a full system replacement is required.
Why does my heat pump seem to heat more slowly than my old furnace?
Because it is heating more slowly, by design. Heat pumps run for longer cycles at moderate output temperatures rather than short, intense cycles at high temperatures. The end result in terms of home comfort should be similar, but the experience of standing over a heat pump vent feels different than standing over a gas furnace vent. If the home is genuinely not reaching the set temperature, that’s a different issue worth investigating.
Is the auxiliary heat on my heat pump expensive to run?
Yes, electric resistance auxiliary heat is one of the more expensive ways to heat a home per BTU. It’s designed as a temporary supplement for the coldest conditions, not a primary heating source. A heat pump that’s running on auxiliary heat most of the time either has a performance problem or is undersized for the home’s heating load, both of which are worth having evaluated.
