Deep factory training on the systems most Anderson homeowners own. We have the diagnostics tools, parts access, and technical knowledge Armstrong dealers carry.

Honest, Upfront Diagnosis

A heat pump repair begins with knowing what's actually broken. We run full diagnostics before quoting, walk you through the findings, and never recommend a replacement you don't need. You get a realistic fix or a clear explanation of when replacement makes sense.

Family-Owned Since Day One

Local accountability means we show up on time, complete the repair right, and pick up the phone when you call with questions. Your comfort is our reputation.

All Major Brands Welcome

While Armstrong is our specialty, we repair Mitsubishi Electric, Honeywell, and other heat pump systems serving Anderson homes and businesses.

Warning Signs

Signs Your Heat Pump Needs Repair

System Won't Heat or Cooling Is Weak — Heat pumps reverse-cycle to provide both heating and cooling—when one mode fails, the logic is often in the reversing valve or a low refrigerant charge. We test pressures, electrical continuity, and valve actuation to pinpoint the failure.
Short Cycling or Frequent On-Off Cycling — A heat pump that cycles on and off every few minutes is burning energy and wearing out faster. Causes include overcharging of refrigerant, clogged filters, or a stuck expansion device. We measure pressures and temperature differentials to confirm the cause.
Frost or Ice Buildup on Outdoor Unit — A thin frost layer is normal; heavy ice is not. An iced-over coil usually means the system isn't entering defrost mode correctly, refrigerant flow is blocked, or airflow is restricted. We check the defrost thermostat, control sensors, and coil cleanliness.
Refrigerant Leak (Hissing, Oily Residue) — A hissing sound near copper fittings, or oily staining around joints, signals a leak. We locate leaks with electronic detectors, repair the split, pull a vacuum on the line, and recharge. Ignoring a leak leads to compressor damage.
Compressor Runs but No Heating or Cooling — If you hear the outdoor unit humming but there's no warm or cool air indoors, the problem is usually refrigerant starvation, a stuck reversing valve, or an electrical failure in the indoor fan. We test circuits, pressures, and component continuity.
Loud Noises From Outdoor Unit — Strange noises signal mechanical wear or debris inside the compressor or fan motor. A squealing belt, grinding bearings, or banging refrigerant line are all fixable—but only if caught early. Ignoring compressor noise risks catastrophic failure.

Schedule Service

Getting Started With Heat Pump Repair

Heat pump problems often look urgent because the system can't heat or cool. But diagnosis comes first—and the fix depends on what we find. Fill out our quick form and we'll schedule a diagnostic visit at a time that works for you. We'll inspect the system, explain what we find, and lay out your options clearly.

Our Process

How We Diagnose and Fix Heat Pump Problems

In-Home System Inspection

We visit your Anderson home and listen to your description—what stopped working, how long it's been running poorly, any noise or appearance changes. We then walk through the indoor and outdoor units, visually inspecting for damage, ice buildup, loose connections, or kinks in refrigerant lines.

Check indoor and outdoor air filters for clogs
Inspect ductwork and blower motor operation
Look for corrosion, cracks, or visible damage
Note any hissing, grinding, or unusual sounds
Photograph issues if replacement is likely

Full System Diagnostics

We connect electronic test equipment to measure what the system is actually doing. This is the heart of repair diagnosis.

Run pressure and temperature tests across the refrigerant circuit
Test electrical continuity on the compressor, reversing valve, and fan motors
Check defrost cycle operation in heating mode
Verify thermostat and control board signal integrity
Measure airflow across indoor and outdoor coils

Honest Assessment & Repair Quote

Based on diagnostic results, we explain exactly what's broken and what your options are. If repair is practical and cost-effective, we quote the repair with parts and labor. If the system is aging or major components are failing, we explain why replacement might make financial sense over time.

Explain findings in plain language
Give you a written quote including parts, labor, and shop supplies
Discuss warranty coverage on parts and labor
Answer questions about ongoing maintenance
Schedule repair at your convenience

Expert Repair & Testing

Once you approve, our technicians perform the repair—whether that's a refrigerant recharge, valve replacement, compressor repair, or component swap. We never leave a repair untested.

Perform the repair using genuine or equivalent-quality parts
Run post-repair diagnostics to confirm normal operation
Test heating and cooling cycles to verify the fix
Document all work on your invoice
Clean up any debris or oily residue

What We Fix

Heat Pump Repairs Our Technicians Handle

Refrigerant Recharge & Leak Repair

Low refrigerant charge destroys cooling and heating capacity. We locate the leak, repair the failed connection or component, vacuum-pull the lines, and recharge to factory specifications.

Reversing Valve Replacement

The reversing valve switches your heat pump between heating and cooling modes. When it fails, your system gets stuck in one mode. We replace the valve, test both modes, and restore full operation.

Compressor Diagnostics & Repair

The compressor is the heart of your heat pump. Electrical faults, mechanical wear, or refrigerant starvation can damage it. We diagnose whether repair or replacement is needed and explain the long-term cost.

Condenser & Evaporator Coil Service

Dirty coils block heat transfer and reduce capacity. Heavy frost, reduced heating or cooling, and higher energy use signal coil issues. We clean, test, and replace coils if necessary.

Defrost Cycle & Thermostat Repair

Defrost failures cause freeze-ups and loss of heating. We repair the defrost thermostat, control sensor, or reversing-valve solenoid as needed to restore reliable winter operation.

Fan Motor & Contactor Replacement

A bad outdoor fan motor or compressor contactor leaves your system unable to run heating and cooling cycles correctly. We replace failed motors and electrical components to restore full operation.

Expansion Device Repair (TXV or Orifice Tube)

The expansion device regulates refrigerant flow into the evaporator coil. When clogged or stuck, it reduces capacity. We clean, adjust, or replace the device to restore flow and comfort.

Capacitor & Run Capacitor Replacement

Capacitors store electrical energy to help start the compressor and fan motors. Failed capacitors cause motors to hum without starting. We replace them and test motor operation.

Common Questions

Frequently Asked Questions About Heat Pump Repair

Maintenance is routine service—filter changes, coil cleaning, system checks. Repair fixes something broken—loss of heating or cooling, poor performance, strange noises, or visible damage. If your system runs but underperforms, or won't heat or cool at all, it's time for a diagnostic repair visit.

Heat pumps move heat in both directions: cooling in summer, heating in winter. They have a reversing valve and defrost controls that AC systems don't use. Heat pump repair requires expertise in both modes; we test the reversing valve, compressor, and defrost cycle. AC repair focuses only on cooling. Our team is trained in both.

A thorough diagnostic usually takes 1–2 hours. We visually inspect the system, run electrical and pressure tests, and check heating and cooling operation. This depth ensures we find the real problem, not just a symptom. A quick "eyeball" diagnosis often misses issues and leads to repeat visits.

That depends on the repair cost, the system's age, and its overall condition. When a repair is modest and your system is relatively young, repair usually wins. When the compressor is failing, multiple components are aging, or a major repair is due on an older unit, replacement is often smarter long-term. We give you both options in writing so you can decide.

We handle heat pump repairs during our regular business hours and will get you scheduled for a diagnostic visit. When you call, describe what your system is doing—no heating, no cooling, or unusual noises—and we'll set up a time that works for you and send a technician out to assess the problem in person.

We specialize in Armstrong ProTeam systems as an authorized dealer. We also repair Mitsubishi Electric, Honeywell, and other major brands. If you're not sure of your brand, describe the system or send a photo—we can usually identify it and confirm we can service it.

Repair costs depend entirely on what's broken. A simple refrigerant recharge is a smaller job; a compressor or reversing-valve replacement is a larger one. We run a full diagnostic first, then give you a clear written quote before any work begins—so you know the cost upfront and there are no surprises along the way.

Replacement parts carry the manufacturer's warranty, and we back our own workmanship with a labor warranty. If a repair we performed fails because of our work during the covered period, we make it right. We document the coverage details on your invoice so you always have proof of what's protected.

Regular maintenance is the best prevention. We recommend a professional tune-up every spring and fall—it includes filter changes, coil cleaning, refrigerant and electrical checks, and defrost cycle testing. Our Summit Comfort Care Plan wraps maintenance into a simple annual cost and gives you priority scheduling if repairs ever become needed.

First, check that your thermostat is set to "Heat" mode and the temperature setting is higher than your current room temperature. If it's set correctly but still not heating, the system likely needs repair—either low refrigerant, a failed reversing valve, or a defrost cycle issue. Don't delay; call us for a diagnostic. Running an electric backup heater to compensate wastes energy and costs more.
