I’m trying to decide what to use in my 1100 square feet. 12’ ceiling, R38 in the attic, no insulation in the 2x4 exterior stucco walls. I live south of Tucson, AZ. I just want to cool my garage in the hot weather months, April through October. It’s usually 105 in my garage during the summer. Do I get just a cool only unit or a heat pump? I’ll never use the heat function.
It depends what they have a lot of units are heat pump when it comes to ductless systems because the parts cost for an added reversing valve on a ductless heat pump isn’t that much more so it’s cheaper for the parts house to only stock heat pumps vs. both cool only. But normally the price diff on ductless is $100 or something very small for heating. Central air/forced air is different for some reason the heat pump condensers are typically a bigger price jump. As far as sizing ask a local contractor but the load on that is probably 2 or 3 tons depending on design temp you’re trying to satisfy. You’re sure you have no insulation in the exterior walls? If it’s exposed (studs are exposed) adding insulation is worth the money it will make the garage way more comfortable before putting in the AC.
Can you help me understand the settings of an ecobee thermostat for dual fuel/gas? I've been told the aux max outdoor temp and compressor minimum outdoor temp should be set higher than the default. What should they be set at for the Front Range? Also, I don't run wifi all the time so how does this effect how it runs? Frankly I'm frustrated at the high electric bills and inconsistent temperatures in my brand new system.
It depends on the system but if you have a cold climate heat pump then it should normally be set lower. If you have a traditional heat pump you have to read its performance charts and set it accordingly but comparing a single stage system vs. a Daikin fit enhanced for example the single stage will lose half its capacity at 5F and be inefficient to run whereas the Daikin fit will maintain a COP of about 2.2~2.5 and maintain 80%+ of its capacity. You just have to set it up based on what you have. Is your backup heat electric or furnace ? If it’s furnace you shouldn’t have high electric bills even with a basic single stage system… I would just strongly consider having the installers adjust it for your climate and system
Are you talking about single stage basic or inverter heat pumps working in the cold. Because I think manufacturers should only make inverter heat pumps that are cold climate for all the states such as Florida and Texas.. I don't think manufacturers should make air conditioners just straight heat pumps. Also we should be using propane or CO2 for refrigerant. We already use propane for heating in furnaces there's no difference in a refrigerant line. Also the government needs to cap electric rates to like $0.10.
There is a big difference between propane pipes used for heating and R290 refrigerant lines. The fuel gas pipes in a home run around half a psi but when used as a refrigerant the pressures are over 100psi. That makes leaks much more likely. But there is an elegant solution: just keep the refrigerant outside. A monobloc heat pump has the entire refrigeration circuit outside and pipes carry heated and/or chilled water inside to air handlers, radiators, in-floor heating, or other emitters. And you can mix and match units from different manufacturers, allowing greater flexibility and easier upgrades.
The only 3 pipe systems I know of are commercial not residential I did not know LG made a heat recovery system for residential use I’ll have to look into it
Wasn't this about air conditioning? Northern Canada? This is just heat pump conversation like any other. Of course in Colorado. Of course it will air conditioning in Denver. 3 min left and the word air conditioner hasn't come. Ul Now we are on tax credits.
Is it time to ban air conditioners that don't have a reversing valve? They have mostly disappeared from the rest of the world. Even mini splits sold in countries where heating is not required, they still have a reversing valve...
There’s more to a heat pump than that you also have the defrost control board etc… no I wouldn’t ban them there’s lots of regions that don’t need heat and should have a straight cool application. Would just raise prices on things. Regulations always just increase prices so no government should leave everyone alone lol
@@TheHVACDopeShow PFAS chemicals in R454b should provide plenty more fodder when liver cancer starts showing up. They'll probably blame it on alcohol is my guess. Give me a how dare you?

Please do a video on 3 pipe systems like the LG Multi V S and how efficient it really is
The only 3 pipe systems I know of are commercial not residential I did not know LG made a heat recovery system for residential use I’ll have to look into it
@@TheHVACDopeShow the multi V "S" is the residential version. I saw it on this old house a couple years ago, but haven't seen much since

Rule the refrigerants, rule the world. (Take the refrigerant away, neither will work.) They coming for your Freon in 2024.
They’ve been coming! lol here comes the planned obsolescence again 🙄
