Ductless 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?

Comments (5)Not familiar with Trane in mini splits but a few comments. I would not be overly concerned about oversizing as inverter mini splits can vary their output. As an example a 24,000 (2 ton) Mitsubishi heatpump model shows in their brochure as being able to throttle down to as low as 8200 btu (.7 tons) and go as high as 2.6 tons. The blower can vary it's flow from 388 cfm to 738 cfm. Typical AC systems have 1 speed that the compressor operates at (although there are more expensive systems that can operate at two or more speeds) . If indeed you purchased a larger system than needed in an inverter mini split it would operate at a lower effective tonnage and not present a problem. Be aware that purchasing a unit over the internet will in most cases result in no warranty. Also, installing the unit yourself will in most cases void any warranty that there might be. Regarding price a 2 ton major brand inverter heatpump mini split with a straightforward installation including a new 220 electrical line might be in the $3750 to $4500 range from an HVAC company....See MoreDuctless Mini-split air conditioning
Comments (2)Thanks for your help, zL700; I like your link for SlimDuct enclosure, much better than my idea for 3"-4" pvc pipe! I plead guilty to a LOT of sharing! Once one reads all the way to the end, my question in the first line was 'history' : "Can anyone support my argument that it is ample to use a dual split unit for just the front two bedroom's? " This would save both cost and a difficult condenser install location. In short: We have a MrSlim MSZ-A17NA single-split 17 Kbtu unit for the 3rd floor finished attic, and a conventional 28 Kbtu ducted unit on the first floor. Our calculated 50 degree day heat loss for the entire house is 48 Kbtu, of which the two rear small bedrooms are only 5 Kbtu each. I have agreed to put in a dual-split 9+9 or 12+12 for the two 2nd floor front bedrooms. Shouldn't this effectively cool the entire 2nd floor? I need technical, experienced opinion to support my desire to avoid having to put in a 3rd condenser in the larger of the two rear bedrooms.

Comments (7)A very general rule of thumb is the installed price is twice the equipment cost. On top of that you have to add additional labor charges if the installation is difficult, during peak season times, etc. It is hard to imagine why this guy is quoting $50K. You need to get more quotes. You want an HVAC contractor who will do a load calculation. If the contractor can't do the calculation then keep looking. Installing a mini-split for a large addition is not a bad idea. How big is the current hot water heater? Most families can use a 40 or 50 gallon hot water heater tank and never run out of hot water. The tall type may be a better fit. I also recommend installing low flow shower heads. Those are now the code for any new faucet. You will be amazed how much hot water you save....See Moremike_home
