HVAC stopped pumping out heat

Not too long ago, our Heating, Ventilation, and A/C unit has halted pumping out heat.  I was thankful it hasn’t been that large of a deal because it really ever gets genuinely freezing where every one of us are living.  But, over the past few days, the temperature has dropped into the teens! When the climate has changed, we all turned up our control unit only to find out that freezing air was being pushed through our air ducts.  This was confusing because every one of us had just had our year Heating, Ventilation, and A/C tune up just before the beginning of winter. All of us tried resetting the control unit several moments and turning the unit off and on again.  This worked for a few days and then the air went back to be chilly again. All of us called our local Heating, Ventilation, and A/C professional and had someone come out right then and there. Almost as soon as the HVAC man arrived, the guy knew what was happening.  Our control unit was malfunctioning and keeping to run the air conditioner even when the heat setting was switched on. All of us ended up having to buy a current control unit which took a few minutes to arrive. Happily, there was a hotel super close to our current home that every one of us were able to hang out at that had a modern current heating and air conditioner unit every one of us could sit back nearby.  After a few days, we all got the call that our current control unit had came in and was due to be set up.
