Heating or cooling has stopped
A complete loss of comfort can become urgent based on weather, the people in the property, and the building itself.
Urgent comfort problems
Emergency and after-hours HVAC service
Air-Exx offers 24/7 availability to answer for emergency and after-hours HVAC needs. Call and describe what the system is doing, whether heating or cooling has stopped, and any condition that makes the situation urgent. If a call is not answered, use the separate text line.
Straight answer
What should I do when heating or cooling fails after hours?
Call Air-Exx and explain the symptom, property location, equipment behavior, and why the condition is urgent. Air-Exx provides 24/7 availability to answer for emergency and after-hours HVAC needs. The next step depends on the specific request and current service conditions.
Before you call
Make the situation safer to describe.
The system is freezing or leaking
Visible ice-like buildup or moisture near equipment deserves attention before repeated operation makes the condition harder to understand.
The equipment appears unsafe to run
Shut the system down when its condition appears unsafe and explain exactly what you observed when you call.
A business system affects operations
Describe the equipment, affected area, and operational impact so the request can be framed accurately.
What happens next
Diagnosis before recommendation.
Call and describe the situation
Share the property location, equipment type, symptom, visible condition, and why the need is urgent.
Clarify the safest next step
The first conversation focuses on what is happening and whether the equipment should remain off while service options are considered.
Confirm the service path
Air-Exx explains the next available path based on the actual situation and current service conditions.
Diagnose before choosing work
When the equipment is evaluated, the finding and firm options should be explained before a repair or replacement decision is made.
Useful context
What shapes the next step.
Availability is not an arrival promise
The exact safe statement is 24/7 availability to answer. Timing depends on the actual request and current service conditions.
Use the separate text path
If a call is not answered, the Missouri text line provides a distinct second way to share the request.
Keep the description factual
Share what you see, hear, smell, or feel without trying to identify a component failure before diagnosis.
Questions that change the decision
Clear answers, in context.
Does 24/7 availability mean someone will arrive right away?
No. The commitment is 24/7 availability to answer. The next service step depends on the request and current service conditions.
What counts as an HVAC emergency?
A complete loss of heating or cooling, equipment that appears unsafe, active leaking or freezing, or a condition affecting vulnerable occupants or business operations may justify an urgent call. Describe the situation so the next step can be discussed.
Can I text about an after-hours problem?
Yes. Air-Exx has a separate Missouri text line. Use it as the second contact path if a call is not answered, and include the property location, system type, symptom, and urgent concern.
Should I keep running a system that is freezing or leaking?
Turn the system off if continued operation appears unsafe or is adding to visible ice or moisture. Explain the condition when you call so the next step can be discussed without guessing at the cause.
