Considering ductless for a small Cape Cod home
hello people, I have a question on some possible scenarios for ductless unit to be put into our home.We have had some estimates and are quite confused. The prices are very similar BUT the brands are different and the BTU’s are different and being complete novices we are baffled. So here goes.
One contractor has the following–
1)Fujitsu 12,000 BTU heat Pump system for our Living room/Kitchen area.- Now the size of my small living room width wise I would say is as follows- When you walk in the front door – consider the wall to your right that wall and going across to the other wall to the left is 240″(20 feet) then if when you walk in to the home from that front door- you can see straight back into the kitchen thru an archway- so that whole length from the from the front wall to the end of the kitchen is 285 “(about 24 feet). Now once you enter the kitchen its width is only 155″(about 13 feet) Remembering that the kitchen leads into Living room but is blocked by a wall except for the archway opening. So there I hope you see the proper outlay for the 2 rooms.
Now each contractor said the exact BTU units for our basement which was 12000 BTU so that is not a question on BTU. But for our 2 small rooms on the main level are also different BTU’s- so here goes with those 2 rooms.
2)the contractor wants to put in a 7000 BTU blower in our bedroom which is as follows-it is 12 feet by 12 feet (simple) and also a 7000 BTU blower in the small den room which is as follows- 132″(11 feet) by 112″(about 9 plus feet). very small rooms. Now as the configuration goes- the small rooms and the basement are to be put on what he is calling a TRI-ZONE Heat Pump system that is 24000 BTU. and he is giving us a 1 year parts and labor warranty. and a 5 year parts only warranty and a 7 year compressor part only warranty.
So there you have one of the contractors proposal.
Now for the other contractor-
Very similar price as mentioned earlier- he wants for the Living room/kitchen-the BRAND is CARRIER-
so for the living room/kitchen- he mentioned a 38MFQ17-what he calls a 17000BTU OUTDOOR unit- and a 40MFQ17- a 17000 BTU Indoor unit?? See our question- the other contractor did not mention the BTU of the outdoor unit but the blower was only going to be 12000 that is big difference to a novice like me- 17000 compared tom a 12000??? The contractor who wants to use the 17000 explains it to us this way- he says that when the temperature outside reaches the 100 degree feel temperature you want that extra power and he says that we can raise or lower the temperature we want it at to adjust to the outside temp and he used the word RAMPS down- that the unit would ramp down when it foes not need to do that much cooling?? Is this true- and you people knowing the size of the connected rooms and its configuration- what is the right BTU?? is 12000 too little and is 17000 overkill?? Oh boy??who to believe??
Next is for the 2 small rooms– the contractor who only wants 12000 for the living room/kitchen wants only 7000 BTU blower for each small room and remember those are the units connected to the TRI-ZONE system- and the contractor who wants 17000 for the large area wants to put in the following- 2 units one in each room-40MAQB09 – 9000 BTU units and a 12000 40MAQB12 in the basement(but forget the basement since both contractors have the same BTU for that area. BUT as you can see one contractor wants 7000 BTU for the small rooms and one wants 9000 BTU???
As for the warranty the contractor with the 9000 BTU units and the 17000 BTU unit has the following- 10 year compressor warranty ,10 years parts and labor and 2 years labor guarantee- which is much better than the other contractors warranty ans stated above?
So to sum it up I hope- one contractor wants for the large area- a 12000 BTU blower and two 7000 BTU blowers with 1 year parts and labor and 5 year part only and 7 year compressor warranties.
The other contractor wants – for the large area a 17000 BTU blower(and a 17000 outdoor compressor) and two 9000 BTU blowers on the tri-zone system with 2 year labor ,10 year parts and 10 year compressor warranties.
remember the triz-zone system is because they are adding the basement to the 2 small rooms on that one outdoor compressor.
So there you have it- we are really confused. First – not sure which is the better unit FUJITSU or CARRIER – I am sure both are equally as good?? And also why is there such a discrepancy between the power of the units. Please explain if you think we should go with the stronger units or the lower BTU units and why. This is a big project for us and we need to do it right.. So please in your answer please try to explain in as simple word as possible- since we really do not know anything about this and once it is done that is it. We thank you for your time and effort and await someones reply.
