Need info on ductless A/C
Comments (2)There is lots of information available on manufacturers' web sites and other sites. The problem in installing ducts in an existing house is that you either have to install a return in every room, or install other means of air transfer to one or two central returns. That means undercutting doors or putting jump ducts or grilles in the walls. Any pressure differential between rooms will cause air to flow into our out of the room through the house's envelope. Any leaks in ducts in the attic will cause air to be sucked into the house at another location to replace that. In your position, I would think seriously about mini or multi splits. You can get wall-mounted and ceiling -mounted indoor units. Where do you live? Do you have window units now? If so, how well do they serve you for cooling?...See MoreCentral AC vs ductless
Comments (32)Folks,in what is becomeing increasing common,ya'll sure wandered a long way from home to debate issues based on speculation,presumption or conjecture. Is it not bad enough contractors fill customer's head's with half truths and lies to cover up deceptive trade practices? If we must get into these things,can we stick to complete facts instead of half truths? In the state of Texas where the issue of licenseing was raised in this thread,consider this. 75% of installs are done by individuals who are not licensed but instead operate under another's license. Of those installations,most times licensee never even see's the site,much less inspect's the work. Texas cover's 268,500 square miles and a single license will cover every square inch and as many employees as the company can keep busy. Compare that to electricians,where not only must they visit every site with their license on file,they must perticipate in every minute of the job. Ditto for plumbers. With all that in mind,consider if you will. The law doesn't require any part of the hvac installation be done by or under the supervisoin of a license holder other than the refrigerant evacuation,charge or disposal by an EPA certificate holder employeed by a licensee and a portion of electrical must be done by a licensed electrician. Occasionally a protion of condensate drain must be done by a plumber. If the homeowner is doing the install,the plumber and electrician are not nessarlly required but refrigerant can not be done by homeowner unless he has credentials. Why you might ask do we even bother with licenseing hvac people? Because a bunch of good ol boys got togeather a few years ago to conspire and run mom and pop operations out of business. They bought off state legislators and the rest is history. Lest anyone think's I am slamming Austin Air,"tant so"and here's why. A.A. is a small company on every job he contracts so the customer recieve's the benifits of his knowledge and training while a neighbor is getting work done by a multi-million dollar entity's surrogate like I spoke of earlier. What does it mean? The guy who unstopp's your toilet or change's the porch light switch has many fold the hours of training than the one who installed your hvac system. If the average gearhead has a friend or can buy a friend to guide him through it,he can install a mini-splt with exception of refrigerant part. With the benifit of a few specialized tools,a dedicated homeowner could install central as well. It is not an endeavor requiring great intelligence or technical ability but the fat cats who bought the law makers will try and make you believe it is.....See MoreHow to convert 1 zone ductless AC to multi zone
Comments (4)If you have 35000 btu from the outdoor unit...it means you can installed 2 indoor with 12000 btu and 1 indoor unit with 9000 btu. https://www.minisplitwarehouse.com/ The Benefits of Zoned Heating and Air Conditioning. If properly installed and designed by a home heating and cooling professional, zoned heating and air conditioning can dramatically increase your comfort and energy efficiency. 1.) Energy Savings When combined with programmable thermostats and Energy Saver mode, you can save up to 35% on your energy costs. By only having to produce a certain amount of conditioned air for the different “zones,” your HVAC system won’t have to work as hard. 2.) Easily Integrated Zoned heating and air conditioning can easily be integrated with your current system. Ductless mini-split systems can also be used for your zoned heating and air conditioning — no ducts required. Keep in mind, however, that for multi-zone applications, you will need to use an outside heat pump. 3.) Improved Comfort and Control Zoned heating and air conditioning are as simple or sophisticated that you want it to be. You can use your programmable thermostat and smartphone apps to have complete control of your home, or you can simply change the temperature manually. Regardless, by being able to change the temperature of each zone, you will have more control and comfort than ever without having to disturb other household members. 4.) Works for Both Heating & Cooling Zoned heating and cooling is a convenient and efficient solution for homes with multiple levels, sprawling designs, and large open areas that formerly relied on supplemental heating and cooling methods....See MoreDuctless A/C and heater question
Comments (5)Maybe you have already done this, but rereading the comments, it jumps right out at me now. I am combining mike-home's suggestion of window units with the need to determine the capacity that you need. Sometimes load estimates are very good and sometimes they are way off. Sometimes they are way off because it is impossible to get a good number for how good insulation and are sealing are, or some other parameter. I suggest that, if you can pull it off, run with a couple of window units for a time with heavy demand. Get data for a few weeks, at least. Pay attention to, or somehow meter, how much the units are running. That way you can have the best possible estimate given the capacity of the window units is accurate....See Morebstruss
