Your furnace will need an emergency furnace repair if you start hearing strange noises while it's running. A clanking, whistling, or rattling sound is not normal and means something is wrong with your unit's components such as the motor or fan.
Loss of heat or cooling: A loss of heat or cooling is considered an HVAC emergency. First, extreme heat or cold can quickly threaten the health of infants, older family members, and anyone who is ill.

Losing your home's heating is considered an emergency when it's 40 degrees or colder outside. Within just a few hours, a lack of heat can cause indoor temperatures to become uncomfortable and ultimately unhealthy, especially for the young and elderly or those with underlying health conditions.

How cold can a house get without heat overnight? The time of day your heater goes out impacts how long the house stays warm. Indoor temperatures go down faster at night, so if your furnace stops overnight, you can expect a quicker decline. This can be as much as 15 degrees Fahrenheit before morning.
Generally, a house will stay warm for 8–12 hours after losing heat. However, without intervention, it will eventually reach outdoor temperatures. If temperatures are frigid outside, maximize the warmth by gathering the family in a small room, wearing many thin layers, and placing towels around windows and doors.
Heat emergencies are of three types heat cramps (caused by loss of salt), heat exhaustion (caused by dehydration) and heat stroke (shock). Remove the victim from the heat and have him lie down. Apply cool compresses, elevate the feet, drink fluids and use a fan to blow cool air. Get medical help if needed.
But that may require taking your landlord to court. Under the implied warranty of habitability, landlords must provide renters with a home suitable for habitation. Under local or state laws, this means providing essential services, including heat.
Heating and hot water issues are often an emergency and need urgent attention.

For indoor workplaces where the temperature reaches 82 degrees Fahrenheit, employers must take steps to protect workers from heat illness.
How Long Can You Run Emergency Heat? Your system can technically run in Emergency Heat mode indefinitely. Whether your backup heat source is electric or fossil fuel, it's designed for continuous operation without causing damage.
The rule of the thumb is that it takes roughly 6-hours for water in your pipe to freeze after left in an unheated area. Meaning if you lose power at your home and the weather is reaching below freezing point, you have approximately 6-hours until the pipes will begin to freeze.
While chances of freezing to death in your home are small, there's a greater danger of death by fire, lack of oxygen or carbon monoxide poisoning. Safety is of extreme importance in a heating emergency.
In general, 80 degrees is too hot for a house if people are inside. However, if people aren't home during the day or for vacation during the summer, an indoor temperature of 80 degrees can save energy until you return and lower the temperature.
