Why Choose Us
What Sets Our Heat Pump Repair Service Apart
NATE & EPA Certification for Complex Systems
Heat pumps are more technically demanding than a standard air conditioner or furnace. Our repair technicians hold NATE certification and EPA credentials specifically for refrigerant and complex heating-cooling systems. You get specialists who understand the nuances, not generalists.
Three Generations of Family Expertise
We’ve been repairing Minnesota HVAC systems for 48 years under family ownership. Heat pump technology has evolved dramatically over that span, and our team stays current with the newest designs — Lennox, GE, Ruud, and others. That continuity of knowledge translates into accurate diagnostics and smarter repairs.
Deep Understanding of Heating-Cooling Crossover Problems
Many heat pump failures show up only when the system switches modes — heating to cooling or vice versa. Our technicians know the reversing valve, defrost cycle, and auxiliary heat settings inside out. We catch the subtle failures that make you lose half your system’s functionality.
Warranty & Transparent Repair Documentation
Every heat pump repair includes written records of the work, parts, and labor performed, plus clear warranty terms. We stand behind our repairs with follow-up support, so if an issue surfaces later, we make it right without hesitation.
Honest Diagnosis on Repair vs. Replacement
Heat pump repair can be cost-effective for younger systems, but an aging unit that needs a major component might be smarter to replace. We assess your specific situation, explain the long-term math, and let you decide with complete facts.
QI Certified & Trusted by Xcel Energy
Our Xcel Energy certification reflects our commitment to efficient repairs and system optimization. We meet a higher standard, and it shows in the work we deliver.
Warning Signs
Symptoms That Indicate Your Heat Pump Needs Repair
Heat pumps are dependable systems, but certain warning signs point to problems that require professional attention before they worsen. Below are the most common symptoms we see in the Bloomington area. If you notice any of them, schedule a service call before a minor issue becomes a major repair.
System Won’t Switch Between Heating and Cooling
Your heat pump should cycle seamlessly between heating in winter and cooling in summer. If it stays stuck on one mode or refuses to switch, the reversing valve is likely stuck or failing. This component controls refrigerant flow direction. A stuck reversing valve means you lose half your system’s function until it’s repaired.
Weak or No Airflow in Either Mode
If you’re running the system but barely feel air from the vents — whether heating or cooling — a frozen coil, clogged filter, or failing blower motor is the issue. A frozen coil in winter reduces heating; in summer, it blocks cooling. Don’t ignore this; it can damage the compressor.
Heating or Cooling Performance Has Dropped
Your heat pump used to keep your home comfortable, but now it takes longer to reach the set temperature. The system runs more often to compensate. This usually points to a low refrigerant charge, a dirty coil, a faulty compressor, or a thermostat that’s lost calibration.
Strange Noises or Vibration
Grinding, squealing, rattling, or unusual humming during operation signals mechanical wear, loose components, or a struggling compressor. These aren’t sounds to ignore — continuing to run the system can accelerate the damage. A professional inspection will pinpoint the source.
Visible Ice Buildup on the Outdoor Unit
In winter, light frost on the outdoor coil is normal during defrost cycles. Heavy ice that doesn’t melt is not. This usually means the defrost cycle isn’t working — from a failed thermostat, stuck reversing valve, or low refrigerant. Ice buildup reduces heating and can damage the compressor.
Outdoor Unit Won’t Run or Cycles Erratically
If your outdoor heat pump unit isn’t running, or turns on and off repeatedly, electrical issues, a failed compressor, or control problems are likely. Erratic cycling wastes energy and wears down components prematurely.
Our Process
Our Heat Pump Repair Methodology
1. Complete System & Mode Analysis
We start by understanding what isn’t working and in which mode — heating, cooling, or both. Then we perform a thorough diagnostic of your heat pump’s dual-cycle operation.
- Test heating and cooling cycles independently
- Measure refrigerant pressure on high and low sides
- Check the reversing valve operation and defrost cycle logic
- Verify compressor functionality and electrical continuity
- Inspect all contactors, capacitors, and control relays
- Test the outdoor and indoor fan motors
2. Clear Assessment & Repair Strategy
Once we understand the problem, we explain it clearly in plain terms and present your repair options before starting any work.
- Identify exactly which component or cycle has failed
- Provide an upfront, itemized quote so no surprises
- Explain whether the repair is a quick fix or more involved
- Discuss repair-versus-replace for aging systems
- Answer every question so you approve the work with full confidence
3. Precision Repair of the Failed Component
Our technicians carry the specialized tools and common replacement parts needed for heat pump repair, so most jobs are completed in one visit.
- Recover, repair, or recharge refrigerant to factory spec
- Replace failed capacitors, contactors, or relays
- Repair or replace the reversing valve if stuck
- Clean or replace evaporator or condenser coils
- Replace failed blower and fan motors
- Fix loose or corroded electrical connections and terminals
4. Full Cycle Testing & Performance Verification
After repair, we run your heat pump through both heating and cooling cycles under load to confirm it’s working at full capacity — not just limping by.
- Verify both heating and cooling modes reach target temperatures
- Confirm refrigerant charge matches manufacturer specifications
- Test the reversing valve switching between modes
- Check defrost cycle operation (if in heating mode)
- Verify airflow at all registers is strong and even
- Listen for any remaining abnormal sounds or vibration
5. Documentation, Warranty & Ongoing Support
We close every repair with written records and clear terms.
- Provide written documentation of all parts and labor
- Explain warranty coverage and terms
- Share preventative maintenance tips for your heat pump
- Leave our contact information for follow-up questions
- Stand behind the repair — if an issue arises later, we make it right
Common Repairs
Heat Pump Repairs We Specialize In
Heat pump failures come in many forms, from refrigerant leaks to electrical issues to failed reversing valves. Our NATE-certified technicians have seen it all and have the tools and knowledge to fix it right the first time.
Reversing Valve Repair or Replacement
The reversing valve allows your heat pump to switch between heating and cooling. When it fails or gets stuck, you lose half your system’s function. We diagnose valve issues precisely and replace it when necessary so you get both heating and cooling back.
Refrigerant Leak Detection and Seal
A refrigerant leak in a heat pump reduces both heating and cooling capacity. We use electronic detection to pinpoint the leak, make the repair, and recharge the system to factory specifications. A properly sealed system delivers full efficiency in both modes.
Compressor Failure & Replacement
The compressor is the engine of your heat pump — it circulates refrigerant in both modes. If it fails, your system won’t heat or cool. Compressor replacement is significant, but our technicians handle it with expertise and warranty the work.
Defrost Cycle Repair
In winter, heat pumps need a defrost cycle to remove ice from the outdoor coil. If the defrost thermostat, valve, or relay fails, ice builds up and heating capacity drops. We diagnose defrost failures and restore winter heating.
Blower or Fan Motor Replacement
If airflow is weak in heating or cooling mode, the indoor blower or outdoor fan motor may be worn or failed. We test the motor and its wiring, and if the motor has failed, we replace it to restore airflow.
Thermostat Replacement or Reprogramming
Heat pump thermostats have special settings for defrost, auxiliary heat, and mode control. A faulty thermostat can prevent your system from switching modes or lose calibration. We test, repair, or upgrade your thermostat to restore full functionality.
Electrical Connection & Control Board Repair
Loose terminals, corroded connections, or failed control relays prevent a heat pump from operating safely and efficiently. Our licensed technicians ensure every electrical connection is secure and meets code.
Common Questions
Heat Pump Repair: Frequently Asked Questions
Heat pumps combine heating and cooling in one system, with a reversing valve that switches refrigerant flow direction. AC repair focuses on cooling; heat pump repair must diagnose both modes and the valve that switches between them. Problems often show up only in one mode — heating works but cooling doesn’t, or vice versa. That dual-function complexity is what separates heat pump specialists from general AC technicians.
A younger heat pump with an isolated failure — a failed capacitor, a refrigerant leak, or a motor — is usually worth repairing. Replacement makes more sense for an aging unit that needs major component work like a compressor or reversing valve, or one that breaks down repeatedly. We assess your specific system, explain the long-term cost of repair versus replacement, and let you decide with all the facts.
If your heat pump is stuck in cooling mode or won’t switch to heating, the reversing valve is likely stuck, failed, or not receiving proper control signal. This is a common cold-weather failure in Minnesota. The system can’t enter heating mode until the reversing valve operates correctly. This requires professional repair — don’t try to force it into heating mode manually.
Heat pump repair costs vary widely — replacing a capacitor is an affordable fix, while a refrigerant leak repair or compressor replacement is more involved. We diagnose your specific problem first, then provide an upfront quote before starting any work. We never charge until you approve the repair.
Yes. We provide a warranty on parts and labor for all heat pump repairs. The specific terms depend on the type of repair and the component involved. We’ll explain warranty coverage clearly when we complete the work and stand behind it with follow-up support.
An annual maintenance appointment before heating season (fall) catches small problems early and keeps your system running efficiently in both modes. We inspect the coils, check refrigerant charge, test electrical components, and verify the reversing valve and defrost cycle. Regular maintenance is far cheaper than emergency repairs and extends your heat pump’s lifespan.
Repair fixes a problem after it’s broken — a failed component, low refrigerant, or electrical issue. Maintenance prevents problems before they happen by inspecting, cleaning, testing, and verifying all components are working within spec. Both matter: maintenance keeps your heat pump reliable year-round; repair fixes it when issues arise.
Yes. We’re a Lennox Premier Dealer with deep expertise on Lennox systems, but we also repair GE, Ruud, and other major heat pump brands. Our NATE-certified technicians work on virtually any ducted heat pump model, so bring us your system and we’ll diagnose and repair it right.
First, confirm your thermostat is set to “heat” and the temperature setpoint is higher than the current room temperature. Check your air filter and replace it if clogged — a dirty filter blocks airflow and reduces heating. If those don’t solve it, call us for a professional diagnosis. A reliable heating system is essential through a Minnesota winter, so it’s worth getting a partial failure addressed rather than waiting.
Not for long. If your heat pump is stuck in one mode or has reduced capacity, running it will stress the compressor and risk a complete failure. If you lose heating in winter or cooling in summer, have it repaired before a partial failure becomes a total breakdown and a much more expensive repair.
