- 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.

Professional Furnace Repair & Maintenance

Furnace repair and maintenance in St. Cloud, MN, help keep your heating system dependable through long, cold Minnesota winters. Air Max provides professional furnace repair for heating problems and preventative furnace maintenance to help reduce breakdowns, improve performance, and keep your home comfortable.


Whether your furnace has stopped heating, is making unusual noises, or simply needs its annual tune-up, our technicians can inspect the system, identify concerns, and recommend the appropriate service.

Get Your Furnace Working Properly Again

A furnace problem does not always result in a complete loss of heat. Changes in performance can provide an early warning that a component needs attention.

Heating Problems

Cool air from the vents or difficulty reaching the thermostat setting.

Uneven Comfort

Uneven temperatures or weak airflow throughout your home.

Unusual Operations

Frequent cycling, strange noises, or a furnace that won't stay running.

Higher Energy Use

An unexplained increase in heating costs without a change in normal usage.

Our technicians evaluate the furnace to identify the source of the problem and determine the appropriate repair. Service may include addressing ignition components, airflow restrictions, thermostat issues, electrical connections, safety controls, or worn components.



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

Prevent Problems With Routine Furnace Maintenance

Annual furnace maintenance gives your heating system a thorough inspection before it has to handle another Minnesota winter. Routine service can identify developing problems, reduce unnecessary wear, and help the furnace operate efficiently throughout the heating season.


During a furnace tune-up, our team may:

  • Inspect and clean key furnace components
  • Check burners and heat exchanger performance
  • Test thermostat operation
  • Inspect airflow and filter condition
  • Check electrical connections and safety controls
  • Lubricate moving components when needed
  • Test startup and shutdown cycles
  • Look for developing repair concerns



Keeping up with furnace maintenance can support consistent heating, better airflow, improved efficiency, and a longer service life. It can also lower the likelihood of discovering a preventable problem during the coldest part of winter.
