I live up in the northern area of the country where the weather gets downright frigid, probably for solid eight or so weeks out of the year there is snow on the ground, ice covering the many streams, ponds, & big lakes, & a frigid chill in the air that you can recognize down to the very bone, then the worst freezing can come at night when the blackness takes over & blowing winds can drop the precise temperature to 25 below zero! It is in these instances that I am truly ecstatic to be living in a nice home with top rated insulation, big thick walls, nicely sealed windows, & a top of the line furnace installed by an Heating, Ventilation, & A/C professional, but see when I had our home built I was greatly aware of the local temperature extremes & I took the appropriate action of seeking out the best Heating, Ventilation, & A/C Company I could find. In these cases you can’t know with your billfold book, but funny enough I found an Heating, Ventilation, & A/C supplier who came with truly high praise who ended up being much cheaper than the competition. The furnace I had the Heating, Ventilation, & A/C supplier install has all the great bells & whistles, including being compatible with a smart control unit; With the smart control component I can simply control the temperature of our home from anywhere in the world! Not that I travel that much however the ability is nice to have, everything down to the ducts was handled nicely by this professional & I am super satisfied. With our furnace & a/c I’ll never have to worry about seeing our own breath while inside.
