Reversing Valve Diagnosis and Repair
The reversing valve switches your system between heating and cooling, and a valve that sticks can leave you with the wrong kind of air. We confirm the valve is the culprit before recommending a repair.
HEAT PUMP REPAIR
When your ducted heat pump blows cool air in winter, ices up outside or struggles to keep your home comfortable in summer, Fesmire Heating & Air Conditioning finds the actual fault before recommending a repair. We are a second-generation, family-owned and operated company based in Pueblo, proudly serving homeowners in Pueblo, Pueblo West and surrounding Southern Colorado towns, backed by 25+ years of experience in the trade. As an Armstrong Air ProTeam contractor, we repair any brand of heat pump in both heating and cooling mode. You get a plain explanation of what failed, your options and transparent next steps.

WHY FESMIRE
A ducted heat pump heats and cools through the same equipment, so a problem can show up in one season and stay invisible in the other. We test the system in both modes, which helps us find faults that a single-season check would miss, from a sticking reversing valve to a failing defrost control.
Fesmire began as a father's company and is now run by his son. When a heat pump stops doing its job, you reach the people who answer personally for the diagnosis and the fix, and that second-generation accountability shapes how we work. Our company story explains where we came from.
As an Armstrong Air ProTeam contractor, ducted heat pumps are familiar ground for us. The repair work does not depend on the badge, though. We service any brand, and if you share the make and model when you call, we will plan the visit around the equipment you actually have.
We work with you every step of the way. After the diagnosis, you hear which part failed, what the repair involves and what your options are. Nothing begins until the plan makes sense to you, which is how we keep our commitment to clear, upfront communication.
Fesmire has been installing and servicing heating and cooling equipment since 2000. That experience helps us read the clues a heat pump gives, such as how it behaves when it changes modes or clears frost, and it lets us give you a straight answer about what is wrong.

WARNING SIGNS
If your heat pump runs but the air feels cool or barely warm, the system is not moving heat into your home the way it should. Causes include low refrigerant from a leak, a reversing valve that has stuck, a compressor that is not engaging or a failed control. Each one needs a different repair, so testing matters more than guessing.
A heat pump switches between heating and cooling by reversing the direction refrigerant flows, and the reversing valve handles that change. When the system heats well but cools poorly, or the reverse, a valve stuck partway is a common suspect. A weak refrigerant charge or a failing sensor can create a similar symptom, which is why we check each possibility.
A light coat of frost on the outdoor coil is normal during cold weather, because the system runs a defrost cycle to clear it. If the unit stays wrapped in ice, the defrost control, a sensor, restricted airflow or a refrigerant problem may be to blame. Do not chip at the ice, because that can damage the coil.
A whoosh or brief hiss when the system switches modes or finishes a defrost cycle can be ordinary. Grinding, squealing, buzzing or a loud rattle is not. Worn fan motor bearings, a loose blower wheel, a failing capacitor or a compressor under strain can each make their own sound, so turn the system off if the noise is harsh and call us.
Many ducted heat pumps include electric auxiliary heat that supports the system when it cannot carry the load alone. If your thermostat shows auxiliary heat for long stretches, or your electric bill climbs without any change in how you heat, the heat pump itself may be underperforming. We look for what is keeping the main system from carrying its share.
A heat pump that starts, runs briefly and shuts off, or one that trips its breaker, is warning you of an electrical or mechanical fault. Failed capacitors, worn contactors, restricted airflow and thermostat problems are all possibilities, and a weak stream of air at the registers can point to the blower or a clogged coil. Do not keep resetting the breaker.
Because a heat pump works through both seasons, regular tune-ups through our residential maintenance plan help catch these problems earlier.
OUR REPAIR PROCESS
Your description is the first diagnostic tool we use. Because a heat pump works in two modes, we want to know what it does in each one before we touch the equipment.
A ducted heat pump has major components both outdoors and indoors, so we inspect each side of the system instead of judging from one.
Running both modes lets us see the fault for ourselves and confirm it with measurements instead of assumptions.
Once the cause is clear, we explain it in everyday language and let you decide how to proceed.
We finish by proving the repair worked in the mode that was failing and in the one that was not.
Call us and we’ll start with step one.

REPAIRS WE HANDLE
The reversing valve switches your system between heating and cooling, and a valve that sticks can leave you with the wrong kind of air. We confirm the valve is the culprit before recommending a repair.
When the outdoor coil stays iced over, the defrost control or a sensor may not be doing its job. We test the controls, correct what failed and check that the coil clears.
If the outdoor fan is not spinning or the coil cannot exchange heat, the system struggles in both seasons. We diagnose the motor, its capacitor and the condition of the coil.
Because the compressor works in both seasons, we confirm it is the real problem before recommending anything major. Your repair and replacement options are explained openly.
Low refrigerant means a leak, and a leak affects both heating and cooling. We locate it, repair it where practical and restore the charge.
These electrical parts start the compressor and fan motors, and a failed one is a common reason a heat pump hums without running. We test them and replace what has failed.
If your electric auxiliary heat is not coming on, or never seems to switch off, an element, relay or control may have failed. We test the circuit and repair what is at fault.
A faulty thermostat or damaged low-voltage wiring can keep a healthy heat pump in the wrong mode or keep it from starting. We trace the signal path and repair the circuit.
Call us and we’ll find the cause first.

COMMON QUESTIONS
Cool air in heating mode can come from low refrigerant, a stuck reversing valve, a compressor that is not engaging or a failed control. Sometimes the system is just running a defrost cycle, which is normal and temporary. If the cool air continues, switch the thermostat off and call us at (719) 240-5109 so we can test the system in both modes.
Light frost on the outdoor coil during cold weather is normal, since the system runs a defrost cycle to clear it. A unit that stays coated in ice, or ice that builds up on the refrigerant lines, points to a defrost control, sensor, airflow or refrigerant problem. Please do not chip at the ice. Turn the system off and call us to find the cause.
Many ducted heat pumps have electric auxiliary heat that supports the system when it cannot carry the load alone. Seeing it briefly is normal. If it stays on for long stretches, the heat pump may be underperforming because of a refrigerant, airflow or component problem. We diagnose the cause, and if a gas furnace is paired with your heat pump, we also provide furnace repair.
A brief whoosh or hiss as the system switches modes or finishes defrosting can be ordinary. Grinding, squealing, buzzing or heavy rattling is different and often points to worn fan motor bearings, a loose blower wheel, a failing capacitor or a compressor under strain. If the noise is harsh, turn the system off and call us before the problem spreads to other parts.
When only one mode fails, the fault usually lives in something that behaves differently between modes. A partially stuck reversing valve, a sensor or control issue, or a refrigerant charge problem can all do it. Because we test heating and cooling separately, we can tell you which one it is and explain your repair options before any work begins.
Yes. We are an Armstrong Air ProTeam contractor, and we service any brand of ducted heat pump, whoever installed it. When you call, share the make and model if you can find them on the outdoor unit's data label, and we will plan the visit around that. Call (719) 240-5109 during business hours and tell us what you have.
A ducted heat pump sends air through your home's vents and ductwork, while a ductless mini-split uses wall-mounted indoor units. Both have an outdoor unit, so they can look alike from the yard. We repair both types and keep the services separate because the components and diagnostics differ. If you have a ductless system, see our mini-split repair page.
Confirm the thermostat is set to the right mode, make sure the air filter is clean and check that the breaker has not tripped. Clear snow, leaves and debris from around the outdoor unit, but do not chip ice from it. If nothing helps, leave the system off and call us Monday through Friday between 7am and 4pm.
Yes. We provide heating, air conditioning and heat pump service for mobile and modular homes, and those systems can be configured differently from a site-built house. Our mobile and modular home HVAC page explains how we approach them. Call and describe your setup, and we will plan the repair around your equipment.
Yes. After we diagnose the system in both modes, we explain which part failed, what the repair involves and what your options are, including replacement when it is a reasonable path. You decide how to proceed, and nothing begins until the plan makes sense to you. Call (719) 240-5109 to request a quote for the work whenever you are ready.
