"Amazing Customer Service"

We used Air Max to install mini-splits in our cabin. The team at air max was incredible to work with - Air Max is one of the best. USE THEM!

- Brad W.

"Excellent Job"

Air Max did an excellent job! They explained the work to me and were professional in everything that they did. They worked really hard. I would highly recommend Air Max LLC. Thanks!

- Corinne N.

"Professional & Considerate"

We have used Air Max services on multiple occasions. They have always been professional and considerate. From the office staff to the professional appearing at our door our experience has been very good if not excellent.

- Debbie D.

"Quick and Efficient"

Air Max came out to our home when they said they would. They did what we ask, and got the job done quickly and they were gone! Can't say enough on this company's service!

- Michael D.

"Very Impressed"

Air Max installed a furnace & a/c combo unit and did a very professional job. Everyone involved with Air Max is helpful and courteous. The owner Keith even stopped back to our house to fix an unrelated repair the day we called in. We were so impressed with the work that was done that we had them come back a few months later to install a humidifier on the new furnace. We highly recommend Air Max and will definitely use them in the future.

- K. S.

"Great Service"

Put new boiler in my son's infloor heat system. They knew what they were doing. System works great now. Couldn't find anyone else to replace it. Great people.

- Dave H.

"Honest Service with Integrity"

I highly recommend this company. They did an excellent job of reconnecting an existing air conditioning unit after we had landscaping work done. Another company was more interested in selling a new unit than providing an honest assessment of the possibility of getting more time out of an existing unit. Thank you Air Max for your honesty and integrity.

- Eric O.

"Very Professional"

Evan was very professional and easy to work with. Our job was completed on time and on quoted price.

Heat Pump Repair & Maintenance in St. Cloud, MN

Reliable Repairs. Routine Care. Year-Round Comfort.

Heat pump repair and maintenance in St. Cloud, MN helps keep your system ready for both Minnesota winters and warmer weather. Because heat pumps provide heating and cooling, they work throughout much of the year and need routine care to maintain dependable performance.


Whether your heat pump has stopped working, is struggling to keep your home comfortable, or is due for preventative maintenance, our technicians can inspect the system, diagnose problems, and recommend the appropriate service.

Call us today at 320-252-5602 or contact us online for professional heat pump services in St. Cloud.

Common Signs Your Heat Pump May Need Repair

Changes in your heat pump's performance can provide an early warning that something needs attention. Watch for these common signs that it may be time to schedule heat pump repair.

Not Heating or Cooling

Your system runs but struggles to reach the temperature set on your thermostat.

Uneven Temperatures

Temperatures vary noticeably between different areas inside your home.

New or Unusual Noises

Grinding, squealing, or other unfamiliar sounds occur during operation.

Frequent Short Cycles

Your heat pump runs briefly, shuts off, and starts again frequently.

Your Utility Bill Is Up

Your heating bill rises noticeably without a change in normal household usage.

Ice or Frost Buildup

Excessive ice remains on the outdoor unit or repeatedly returns after defrosting.

Our technicians evaluate the heat pump to identify the source of the problem and determine the appropriate repair. Service may involve airflow problems, electrical components, thermostat operation, refrigerant-related concerns, defrost controls, or other system components.


Addressing problems early can help reduce unnecessary wear and prevent minor issues from becoming more serious.

What to Do If Your Heat Pump Stops Heating

If your heat pump stops providing heat during cold weather, check your thermostat for a setting labeled Emergency Heat, EM Heat, Auxiliary Heat, or Aux Heat. On systems equipped with backup heat, this setting can allow the secondary heating source to provide warmth while the heat pump is not operating.


Emergency or auxiliary heat is intended as a temporary backup, not a permanent solution. If you need to use it because your heat pump has stopped working, call us at 320-252-5602 so our team can diagnose the problem and restore normal operation.

Prevent Problems With Routine Heat Pump Maintenance

Because your heat pump can operate during both heating and cooling seasons, it may accumulate more operating hours than equipment used during only one part of the year. Routine maintenance gives our technicians an opportunity to inspect system performance and identify developing concerns.

 During a Heat Pump Tune-Up, Our Team May:

  • Inspect indoor and outdoor components
  • Check and clean accessible system components
  • Inspect airflow and filter condition
  • Check thermostat operation
  • Inspect electrical connections and controls
  • Check refrigerant-related system performance
  • Inspect the outdoor coil and unit condition
  • Test system startup and shutdown
  • Check heating and cooling operation
  • Look for developing repair concerns



Keeping up with routine maintenance can support reliable operation, efficient performance, and a longer service life. It can also reduce the likelihood of discovering a preventable problem when you need your system most.

 FAQs About Heat Pump Repair & Maintenance

  • How often should I schedule heat pump maintenance?

    Because heat pumps provide both heating and cooling, routine professional maintenance is important for dependable operation. Your technician can recommend an appropriate maintenance schedule based on your equipment and how heavily it is used.

  • Why is my heat pump running but not heating my home?

    Airflow restrictions, thermostat problems, electrical issues, refrigerant-related concerns, or outdoor-unit conditions can all affect heat pump performance. A technician can inspect the system to determine the cause.

  • Is frost on my heat pump normal in winter?

    Some frost can develop on an outdoor heat pump during cold weather, and the system normally uses a defrost cycle to remove it. Heavy ice buildup or ice that does not clear may indicate a problem that needs attention.

  • What should I do if my heat pump stops working in cold weather?

    Check whether your thermostat has an Emergency Heat, EM Heat, Auxiliary Heat, or Aux Heat setting. If your system is equipped with backup heat, this may provide temporary heating until your heat pump can be inspected.

  • How much does heat pump repair cost?

    Heat pump repair costs depend on the problem, the components involved, and the work required to restore proper operation. Contact our team at 320-252-5602 to discuss your system and schedule an inspection.
