Marty is the ONLY A/C guy to understand the sense of urgency when it comes to getting the A/C fixed when it's hot outside! He arrived same day to assess and had A/C up and running again within 24 hours. Highly recommend.

Marty of Just Us Refrigeration is a blessing! He worked hard to get the warranty company to get parts approved and then came out as soon as he got the part to get it replaced so I could have heat. Thank you Marty!!

We called another company to diagnose our heat pump issue. They quoted us $7500 for a repair and $13000 for a replacement. Just Us came out and in 1 hour and $85 later it was fixed! Thank you !!!

Common culprits include obstructed or dirty condenser coils, a failing thermostat, compromised fan motors, or a leak causing a drop in refrigerant levels.
Heavy frosting is typically a symptom of poor airflow—often due to clogged filters or coils—a breakdown in the defrost heating element, or a breach in the door gaskets allowing humid air to enter.
Because refrigeration units are closed-loop systems, they shouldn't "run out" of refrigerant. If levels are low, it signifies a leak that requires a professional repair rather than a simple refill.
Grinding or clicking often points to worn motor bearings or a stressed compressor. To avoid a complete mechanical collapse, power down the system and contact a specialist immediately.
This inconsistency is often linked to a failing expansion valve, inadequate water flow, or insufficient refrigerant.
Most manufacturers suggest a professional tune-up every six months. However, facilities with high-traffic or heavy-duty usage may benefit from quarterly inspections.
A standard check-up involves clearing debris from condenser coils, verifying refrigerant charge, testing electrical components, inspecting seals, and ensuring drain lines are clear.
To prevent the growth of mold and harmful bacteria, these units should be thoroughly cleaned and sanitized at least twice a year.
Life expectancy varies by equipment type and usage, but most commercial refrigeration hardware is built to last many years with proper preventative maintenance — contact us for a professional assessment specific to your equipment and usage conditions.
Replacement is often the wiser investment if the machinery is over 10 years old or if the repair costs are becoming frequent. A common industry benchmark is replacing the unit if its age multiplied by the repair estimate exceeds $5,000.
Yes, emergency repair services are available 24/7 to help businesses mitigate the risk of inventory loss and operational disruptions.
Minimize door openings to trap cold air. Be aware that food safety becomes a primary concern if the power remains out for longer than four hours.
Qualified technicians possess the necessary certifications to manage hazardous refrigerants and complex high-voltage systems safely while remaining compliant with EPA standards.
