All that thermostat indication is saying is that the heat is supposed to be on. If you hear the fan running for a minute or so after the heat indicator has gone out this is normal as the fan is blowing out the remaining residual heat in the furnace after the flame has gone out. The same works in reverse once the stat indicates a call for heat the fan does not start for a minute or so to allow the furnace to heat up and not to blow cold air into the space at start up.
HVAC basically stands as Heat ventilation and air conditioning. As the name indicates it used for cooling the engine parts
HVAC in a car is the Heating, Ventilation and Air Conditioning system.
HVAC air conditioning products cost $3100.00 at the website Northern Tool. HVAC air conditioning products cost $10955.00 at Lowe's. The cheapest ones are at Walmart though for about $120.
This question is a little vague, but I'll make by best attempt. I am assuming you mean a whole-house HVAC unit, and that you are concerned with a possible power surge so you want to shut the unit off at the thermostat. If this is correct, you need to know that the thermostat doesn't control the HVAC unit the way a switch controls a light fixture. As long as your HVAC breaker is on, you will have AC power at the HVAC unit. This usually includes at least a condenser unit outside and a blower either outside or inside. All the thermostat does is tell the HVAC components when to use the power applied and when to do nothing. The power does not flow through the thermostat to the HVAC like power through a switch to a light. Think of it this way: 'Off' on the thermostat doesn't mean power off. It means 'power available, but unit not running'. So, if you want to protect your HVAC from the potential of a power surge you will have to shut off the circuit breaker(s) feeding the HVAC components, not the thermostat.
Degree programs in heating, ventilation, air conditioning (HVAC) or HVAC installation and repair, home appliance repair or, with more education, HVAC engineering
Heating, Ventilation and Air Conditioning
When it comes to safe products especially for the environment HVAC air conditioning systems are a must. The benefit of having one is that they are safe.
HVAC Technician or HVAC Tech or HVAC Mechanic or The AC Guy
Typically an air conditioning or HVAC engineer will the deal with the installation, maintenance and servicing of air conditioning units

HVAC is short for heating, ventilation and air conditioning. So an HVAC job would be any job to help with climate control, such as an AC repairman.If you have any other questions, look up Reynolds Air & Heat and check out our blog posts.
