Need advice re replacing HVAC unit in 1200 sq foot condo
Comments (14)I CHOOSE THIS: https://www.minisplitwarehouse.com/ Bid #2 Install price is $6,295 Warranty: 20yr for furnace heat exchanger...10 yr for all other components 10 yr on all components of condenser and coil 5yr on thermostat and all other components Heating: 1 Lennox ML180UH045P24A (80% efficient) 45,000 BTU input single stage furnace Cooling 18,000 BTU 1.5 ton 13 SEER 410A refrigerant: 1 Lennox 13ACX - 018 condenser placed level on high impact base...See MoreNEED HELP...Lennox HVAC Package Recommendation?
Comments (4)I am not that familiar with the Lennox equipment. You can do some research on their web site to see what is available. Look for models that have the features I suggested. For you house and location I would think a 3 ton AC condenser and a 80K BTU furnace at 95%+ efficiency would be appropriate. But you should still have a load calculation to confirm the sizes. Low humidity in the winter is usually caused by leaky windows and air infiltration. It should not be a problem with a new house especially if it has a basement. Humidifiers become maintenance headaches so it is best to avoid them if possible....See MoreReplacing HVAC system - Trane vs Lennox
Comments (4)The Lennox is a 14 SEER / Trane XR13 would be 13 SEER. I suppose the higher blower efficiency might turn the Trane into a 14 Seer or maybe just below that. (I'm guessing) However, The Lennox is a 14 SEER out of the box paired with something that is likely to have a somewhat efficient motor too because the older less efficient PSC motors in air handlers and furnaces are no longer used circa July 2020 or so all furnaces and air handlers required to use ECM motors. All that said... the installation / design of such is more important than the brand. The downside with either of these brands is the cost of repair parts. Once that part warranty runs out in 10 years or so won't matter much. Also any new AC systems being sold right now will be more or less obsolete within a few years (New Freon phase out). In that sense I guess I'd have to say cheaper is better for now because another replacement is coming in short order....See MoreNew Fully-Variable Communicating HVAC System (Lennox, Trane, Carrier)
Comments (6)1. Does anyone have experience with any of these systems, or know of any reason to go with one brand over another (specifically with respect to this type of system). Of these major brands you list, some may limit the variable nature of which these systems are capable of. Not sure if they still do this or not, but the Carrier models of the recent past limited their models to 5 speeds. Things change with time, so these models may no longer be made. The other is proprietary controls. Some you can use older controls at a cost to performance as in most cases using older controls will turn the machine into a two speed machine. None of these brands AFAIK or can prove make the parts "namely the compressor" -- that drive these units. Nearly every part that makes the machine run are made in other countries and at best are merely "assembled" in the US. If the pandemic has taught me anything... assembled in the USA is NOT the same thing as "made in the USA". Whether you buy a fully variable speed AC (Inverter) or not, these things are the same for lesser models. 2. In particular, does anyone have experience with the proprietary thermostats that you use with each? This is my biggest reservation. You need to use the communicating thermostat that goes with the system, and I am concerned about that kind of proprietary tech from a company that isn't in that business. There are all sorts of reviews that the thermostats are incredibly buggy, updating constantly, and the tech is clunky. Why nearly all major brands chose to take this approach to control their upper end variable (inverter) systems I believe is partly to cut out the nests, and ecobees of the world. But with that comes trouble. Namely expense and as you suggest buggy kinds of problems. There is another brand of Inverter that doesn't do it this way. All you need is a simple 24 volt signal and the "smarts" is in the outdoor condenser. (Bosch) Another brand that has gotten away from proprietary thermostats is Amana. However the Amana will require the Amana furnace paired for their inverter as the furnace contains the communicating functions to communicate with the outdoor inverter. Communicating is buggy for similar problems that make your internet connection go down. Because they use thermostat wire connecting parts and pieces of the system to the "network" that runs or tells the AC system "what to do". So any connection problem or interference can cause intermittent "communication problems". The Bosch Inverter solves those problems completely. As it's doesn't rely on communicating the way the big box boys chose to do it. The problem? Bosch is a disruption type technology. There is risk when competing with goliaths in the industry, for fear they squash you like a bug. The manufacturer or "owner if you will" of Bosch tech, doesn't make the unit they designed. They went out hired a manufacturer to make it so it's German engineered and made in China. Currently Bosch are back ordered here and have been for months... but you may find the same thing when dealing with major names as many of these parts made to make these systems come from place like China and elsewhere. 3. There seems to be a lot of advice that the installation/installer matters more than the system in many ways. Installation matters. In the realm of variable speed AC systems / heat pumps (Inverter driven) -- This equipment is expensive, requires a good amount of knowledge above that of installing a traditional single or two speed machine. In the communicating realm of machines one must also know what causes networks to go down and be able to fix those problems in addition to everything else we must know. Some HVAC companies that don't get into these Inverter driven or "proprietary controlled" things are more likely to try and talk you out of it. They are also dangerous --- touch the wrong thing the right way and you could become a krispy creme. While one could argue a simple single speed system is also dangerous. ----------------------------- I chose the Bosch Inverter for my own home in Katy, Texas in October of 2019. I don't regret that choice yet. Reasons: cut my electric bill in half. Does a much better job dehumidifying. In a more mild climate like Seattle... I believe this choice has more to do with electricity costs and better over all comfort. Many parts on the west coast pay a higher utility rate so these machines can pay for themselves over time and use....See Moretigerdunes
