Visual explanation
Caption: Emergency first: safety, then service — a simple learning aid, not a remote diagnosis. It teaches the order of decisions: danger first, then the service call, then a decision based on the written report. Never a repair approved in the dark.
What you can safely check
Danger first — these are not repair calls:-Gas smell:Leave the home. Do not touch light switches, do not use a phone inside, do not light anything. From outside, call 911 or your gas utility (see Q97). -Carbon monoxide alarm:Get everyone outside at once and call 911 from there (see Q98). Carbon monoxide is a poisonous gas. It has no color and no smell, so you cannot detect it yourself. And heating system can be one source of it. -Smoke or fire:Leave and call 911. -Signs of heat illness— confusion, fainting, hot and dry skin: call 911 first and get the person to a cooler place (see Q96). A house can be re-cooled later. A person cannot wait.
If there is no danger:- Note the thermostat setting, any error message. When the heating or cooling stopped. Describe those on the call. - You may look once at the air filter (is it clogged?) and the breaker panel (has a breaker tripped?). If a breaker has tripped, you may reset it once. If it trips again, stop and leave it alone. A breaker that keeps tripping is reporting a fault. - Do not open system panels. Do not keep restarting a system that smells of burning.
What might be causing this
A system that stops at night has usually stopped for an ordinary reason. A failed part, a tripped safety switch, a clogged drain. But no one can name the cause over the phone. That is what the diagnostic visit is for. The technician checks the symptoms and the affected system, explains what failed. Gives you a written diagnostic report and a written repair estimate. No repair begins until you approve it.
One honest caution: a visit that happens tonight does not mean every repair can be finished tonight. Many common faults are fixed on the spot once you approve the estimate. A part that has to be ordered takes longer. The technician will tell you so plainly.
When to call a professional
Call (682) 438-8127 for emergency availability when the failure cannot safely wait. And say if an infant, an older adult. Anyone who could be harmed by heat or cold is in the home. That shapes how the call is prioritized. Ask Texas Heat & Air what maintenance plan options are current. Get the full terms in writing before you enroll. But a call involving danger always comes first — membership status never outranks safety.
Ask Texas Heat & Air to confirm the diagnostic fee when you book.

| No cooling in extreme heat, vulnerable person at home | Call for emergency availability; get people to a cooled space meanwhile |
| No heat on a freezing night | Call for emergency availability |
| Strange noise, or a smell of burning | Turn the system off; call and describe it before restarting anything |
| System running but weak, home still tolerable | Ask Texas Heat & Air to confirm the diagnostic fee when you book. |
