I'm so confused over Mini-Splits, Central A/C and Heat Pumps
Comments (5)heat pump, central air and heat and a mini split as far as cost of operation? heat pump same as central air and heat except that the heat pump provides the bulk of the heat. this is what I recomend to my clients based on savings compared to electric strip heat. with heat pumps the electric strip is emergency heat and for when temps are 30 degrees..which is not that often for us. central air is electric strip heating only. the most expensive way to heat your home. (espically if you have entergy for your utility provider) mini splits are pretty cool. expensive but fit a lot of needs and great for tight retrofit spots. the condensing unit goes outside like with any set up, but this is where it changes. in each room the air is provided by a wall mounted air handler unit. the condensing units are up to 3 tons. each room would have the ahu..this is what they are calling zones. cost is higher, but you don't have ductwork, so it evens out a little better. with the foam insulation & low e windows your tonnage of ac required will be less. although I don't recomend 'rule of thumb' sizing instead of the ususal 400 to 500 sq ft per ton, your house will be more in the range of 600 to 700 sq ft per ton. oversizing will cost more to operate, wear the equipment out sooner, and will NOT dehumidify. be diligent in finding out what is being spec'd for your home and what options are available for you. some systems will qualify for tax credit, and it is always a good idea to do better than the legal minimum allowed by law (code). in what part of La. are you building? best of luck....See MoreDuctless Mini-split air conditioning
Comments (49)Hello, Would like to know how many BTUs (for 1 wallmount system)would I need for two floors of 690 sqfeet (each floor). The Unit will be on the 2nd floor in the middle between 2 bedrooms and a washroom (over washroom door facing master bedroom). It will be a dual split system. ------------------------------------- Also would like to know which is a safe reliable cost efficient brand, example of wall mounted (split systems) air conditions I've heard of: Fujitsu (they give 10 years warranty parts and labour) Mitsubishi (6 yrs parts and labour however been making them longer) Daikin (6 yrs parts and labour) Igloo York Carrier Grey All about the same price... ----------------------------------- Finally, is it better to get a dual system (with heat pump), from my understanding they are almost the same price and the advantage is that it has a variable BTU which may save some $$. Since the heat pump will be at the higher level then it wont heat as much however it is coming at about the same price. Then again more electronics in a system more chances of malfunctioning sooner? Thank you, Stelios...See Moremini-split ductless system
Comments (8)Hi ionized. Our issue with running actual ducts is that our house is very, very, very old and the original very, very, very old part of our house is solid one foot thick log walls. Going through them at any point is a nightmare for anything. We have a new addition, which would be fairly easy to run duct work, but working it into the old part of the house, which also has only 7' ceilings which are completely open ceilings with timber joists (bark still on them), which we plan on leaving open. We plan on adding some sort of insulation in the flooring between levels but between solid walls, no actual ceiling space and of course no basement, a "ductless" system is seeming the better way to go. Also, no we have no natural gas. Not knowing a whole lot, I would guess I need to run it into 6 rooms. 3 bedrooms, living room, dining room/entry, and kitchen. Right now our coal heat is actual a free standing base burner coal stove, so not central heat. Real turn of the century stuff, but believe it or not seriously efficient and the more insulated the house gets the less I think I need heat other than it, except for the fact I am living in the turn of the century stoking a coal fire daily. Because of the log wall set up the only room that is left out is our new MB. It is on the outside of the log house in the new addition and not on the same level as the stove. So the circulation just doesn't get there very well. There is also the more temperate times of year like Oct. when it would be nice not to be running the stove and have easy access to heat at night if it gets to 30 like it did the other night. My few real questions are do I need to have an additional heat source like baseboard heating for this type of unit? I saw a Youtube video that said if it gets too cold they don't run right. Would my coal stove be OK (we have no plans on getting rid of it and will continue to burn it in the coldest months of winter), or would I then have issues in my MB if I didn't get enough heat up there if the temp dropped? Aslo, I read somewhere and now I can't find where, that there were 35' maximums on the length you can run from the compressor outside. Is this true of all systems or did I read this on one site or someone talking about one manufacturer? If so I am thinking I need two compressors to service different areas of the house, is this how the cost starts adding up quickly? And do I need to hire a professional to install it? I promise we are not average DIYers. We would not be ready to install the entire system at once at any given time. I was hoping to educate myself, decide on a system, buy the parts we need as we go room to room. We are slowly working our way through the house, but we are probably looking at a 8 year total project....See MoreMini-Split Ductless Heat Pump
Comments (8)I am loosing my mind or someone deleted my statement that I live on the (South) Gulf Coast! That is a very important part of many of my comments on house issues. It is obviously very hot and humid here. Your BC situation is so very different so I can't really speak the practical side of your heating issues. No, I did not install it myself. I got a guy that's been teaching at the local trade school forever as far as the local installers go. He did not have much experience with minisplits and called in a collaborator for the job. They did a really nice job running the tubes and electrical through interior walls. The house is raised over an open crawl space so I don't have anything but the outdoor units visible outside. Now I have three whereas before I had two conventional two-ton compressors, one AH, with a gas furnace in the attic. I mostly looked into Sanyo, Toshiba and Mitsubishi. They all have advantages and disadvantages wrt operating features. I do not know your climate so my main concern would be low temp heating performance. Here if you have enough cooling in a heat pump, you can not really run out of heat. One thing I have noticed, but don't understand is that the single minisplits are more efficient and better at low temp than the multi systems. There has to be an engineering explanation or they are just a year or two ahead with the single systems and the designs will trickle over with a delay. Overall, we really like the system. It fits our lifestyle. We are out a lot, and the house has its original doors and walls intact. The inherent zoning feature should save us a lot of money over the years since we will have less expense for conditioning of rooms that are not occupied at different parts of the day and night. My systems are mounted high on the walls. It was very cold for my area when we went into operation so it got a good test. One thing that I noticed is that the programming could be better for heating. The inside blowers go to slow mode when the temp approaches the set point. This makes them good ceiling heaters. (That seems pretty predictable. I've lived in homes in predominantly cooling climates with both supply and return located in the ceilings.) Bumping up the blower speed manually solved the problem. I suppose that the ceiling fan might have done the same thing. One thing I am very glad that I did was to change the first plan to put the units at the head of the beds in a couple of rooms. I was actually concerned that the cool air would cascade down on heads at low blower speed. That might have been a problem, but it would have been even more annoying to have hot air on the face in the "winter". Keep in mind that you can mix and match. If I had not gone entirely with minisplits, I would have had a regular forced-air system and installed one mini in the rear utility room. The duct to that area originated in the attic, ran vertically down a chase through the house and under 2/3 the length of the house to three registers in the floor in that room. It was a weak point to keep in a main system. The expense of mixing systems like that might depend on how capacity breaks down in choosing a "main". Finding a good installer who is experienced with minisplits might be difficult....See Morejcthorne
