I have a lennox heat pump system. A sequencer has gone bad. specs are H1-110 C1-110 TOD 15SH4 Im looking for a new one and all I can find are 2 white rogers units. 2 switches 1 timing for each. H1-20 C40-110 for 24A343 or an H30-90 C1-30 for 24A344 So what can I use or do I need to find a diff. maker than White rodgers?

Hi, Im not a professional at this and I barely know some of these technical terms so please bare with me. We have a major temperature diff in our master bedroom compared with the rest of the house. The Masterbed room is over our 2car garage. During winters the room gets very cold even though the heater is on which I usually set it to 80F and I cant go beyond that as it heats up the other rooms tremendously. Its been 6years since we moved into this house. Initially we thought its because of the garage. That definetly is one reason and I want to do something about it to fix the problem. I want to know what I can do about that to make it better. The other reason I think is - it is a fairly large room and has only 2 vents to the left most side of the room. This left most area in the room can only be used for seating and as a passage to the bathroom and a walkin closet. The sleeping area and the thermostat are on the right most side of the room which doesnt get much heat and always is very cold. Is it possible to extend the duct work to the right side of the room and have couple of vents on that side. If yes, then what type of contractors should I be looking for? Thanks
