Don’t use emergency heat mode unless your heat pump stops heating your home altogether. If that happens, contact a professional heat pump repairman for help.
Does EM heat cost more?
Using Emergency Heat May Cause Higher Heating Bills: Emergency heat is more expensive than its traditional counterpart, so you will probably see a spike in your utility bills if you need to use it. You should use emergency heat for the shortest period of time possible.
What is Heat vs EM HEAT?
The supplemental heat is also referred to as second-stage or back-up heating, with first-stage being the Heat Pump only. Emergency Heat is when you use your supplemental heat (2nd stage) by itself, without the use of your heat pump (1st stage heat).
How does EM heat work?
Emergency heat=using the electric heat strip constantly OK, so when you turn your thermostat to emergency heat, your heat pump will stop trying to extract heat from outside to heat your home inside. Instead it will use ONLY the backup heat strip to heat your home. So, your heat pump has now become an electric furnace.
Why is my heat blowing cold air?
Your furnace may be blowing cold air because the filter is too dirty. A dirty air filter blocks airflow over the furnace’s heat exchanger, causing it to overheat. When overheating, your furnace can trip a high limit switch, causing the furnace burners to shut off so that the heat exchanger does not crack.
Why is my car blowing cold air instead of heat?
A car heating system blowing cold air can be due to a faulty thermostat, low coolant fluid level, malfunctioning heater core, a leaking cooling system, or problems with heating controls and blend door.
Can you run a furnace without a filter?
Technically, you can temporarily run a furnace without a filter. The consequences of running a furnace without a filter include: Poor air quality: For one, not having a filter in place means there is nothing to prevent dust and debris from being sucked into your furnace and recirculated throughout your home.
Where is the reset button on my furnace?
All furnaces are equipped with a reset button. They are generally red or yellow and are located inside the blower compartment. The reset button is a safety feature that will shut down the furnace when a problem is detected, often a hot or overheating furnace, before it trips the circuit breaker.
When should a furnace be reset?
If your furnace doesn’t have any air coming out at all and the pilot light is out, it’s worth it to try resetting the furnace. If this doesn’t work, there may be a problem with the thermostat setting, the power, or the gas line.

Why is furnace not working?
A clogged furnace filter can cause a furnace to shut off. Dirty filters are the most common cause of furnace problems. Dust and dirt restrict airflow—and if the filter gets too clogged, the heat exchanger will overheat and shut off too quickly, and your house won’t warm up.
What to check if your furnace isn’t working?

Can I relight the pilot light by myself?
Pilot lights were once standard on all gas furnaces, but newer systems don’t always contain pilot light ignition systems. Instead, some newer furnaces use electronic ignition systems. Often, homeowners can relight the pilot themselves.
Do all furnaces have a pilot light?
For many years, furnaces used a small and continuously burning flame known as a pilot light to ignite the burners during every heating cycle. Although pilot lights are still present in homes with older systems, most newly installed furnaces use an electronic ignition instead.
How much does it cost to relight a pilot light?
Most service providers will charge a standard fee per visit that typically covers the cost to relight a gas water heater. This service call price can range from $80 to $100. Have you ever relit your own pilot light?
Is it dangerous to leave a pilot light out?
Can a Pilot Light Outage Be Dangerous? The worry here is that when a pilot goes out, the gas valve that supplies the fuel for the pilot flame could still be pumping gas. This can mean a buildup of gas, and when the pilot is relit or relights itself it could result in a very serious explosion.
How dangerous is lighting a pilot light?
If this leak continues, its concentration may reach a point where a spark – such as that from a cigarette lighter, static electricity, or even the pilot light itself as it is re-lit – will cause a fire or even an explosion.
Does gas still flow when pilot light goes out?
The pilot light is a small gas flame that stays lit all the time. When the thermocouple senses a lit pilot, it leaves the main gas valve open. If the pilot light is out, or isn’t burning hot enough, it closes the valve, cutting off gas flow so it won’t build up inside your house.
Are pilot lights always on?
The pilot light can be a “steady-on” pilot, or an ‘intermittent” or an electronic ignition system. The later type of pilot light is only on when the valve is open and the fireplace is operating. A millivolt valve utilizes a pilot light that is always lit.
Does gas ducted heating have a pilot light?
There is no pilot light to go out on a central gas heater — and no chance of gas escaping into the room — which also means you cannot ignite the burner manually.
Can a pilot light cause carbon monoxide?
A yellow or orange pilot light will produce carbon monoxide – an odourless, colourless gas that can fill your home and cause carbon monoxide poisoning. Symptoms of this condition include dizziness, headache, fatigue, nausea, unconsciousness, brain damage and death.
What appliances have a pilot light?
A pilot light is a small flame that is kept lit in certain gas-fired appliances like your furnace, water heater, and gas fireplace.
Why is natural gas dangerous to life?
Natural gas is non-toxic (non-poisonous), but can cause death by suffocation if the gas displaces the air in a confined space. At 25 to 30% gas in air, the oxygen deficiency can cause ringing ears, euphoria, and unexplained behavioral changes.
What Colour should the pilot light be on a boiler?
