Carrier Infinity a/c UV light and dehumidifier questions
Comments (13)Saltidawg, "So why does your thermostat even have a Humidity setting- with a Maximum setting of 65%?" That was EXACTLY what I was wondering. What I learned is this: The maximum setting tells the system to go to work - if the maximum setting of 65% were ever reached, it would cause the system to work more to pull the humidity down. By turning the thermostat humidity setting to OFF, I removed simply the maximum setting from the equation. My misconception was in thinking I could set the humidity to 60 or 65% and it would go UP to that level. Not so. And now that I understand just a bit better about the setting and what it's for, I will turn the Humidity setting to ON, and not concern myself about it as long as it's comfortable in here. And, yes, the temperature was controlled just fine as the humidity went from 45 to 50%. The Carrier Infinity brain controls so much of what goes on, it's hard for mere mortals to know what it's doing and why. I think the biggest thing I learned is that service techs are trained as sales people, too, (at least where this Carrier Infinity system is concerned) and to question whatever advice they give before purchasing anything. I would have spent more than $1000 on an unnecessary UV system if I had listened to the tech without question. Caveat emptor! Buyer beware!...See MoreCarrier quote and coil ?
Comments (4)tstrong you are going down in size of condenser. why? do you have a load calc to support that decision? post model number of evap coil quoted. it makes a difference. new and correctly sized refrigerant lineset or existing to be flushed? a nice system. larger coils used on new systems are typical for reaching higher performance/efficiency numbers. nothing wrong with keeping existing Goodman furnace but you will leave all those rebates and tax credit lying on the table. post back. IMO...See MoreCarrier 3 ton coil replacement
Comments (2)The company is going to mark up any work they perform. They aren't just paying the worker(s) installing the coil, but also covering the cost to run the company, so that they can provide that good service you've been pleased with. They have to recover all remaining refrigerant, vacuum the system down, remove the current coil, install the new coil, connect the new coil to the ductwork, put in new refrigerant, test for leaks, and charge the unit properly. The $675 does not sound unreasonable all things considered. This could be a 3-4 hour job depending on whether the guy has a helper....See MoreEvaporator Coil for new Carrier we are buying
Comments (17)Agree with TD. Noise issues are ductwork related. Higher efficiency systems will move more air than the older systems 15+ years ago because the variable speed motors are smarter and will work harder to move the programmed air volume even at higher duct pressures -- caused both by undersized and poorly designed ductwork (likely the route cause of your comfort problems as well, not equipment capacity/tonnage). This creates the air movement noise that you hear. So yes, the 100k furnace will be louder than the 80k furnace if ductwork modifications are not made (it would likely not use high stage much, however). If a load calculation were done properly I would not at all be surprised to see the 80k furnace be more than enough. The output capacity of the 97% efficient 80k btu furnace is not much less than that of the older 80% efficient 100k furnace. I might call back the one that said go with the 80k. Yes you do want the Carrier aluminum coil. That is what you listed above as confirmed by TD. Best course of action is to have the dealers inspect your ductwork and make corrections to match the air volume requirements of whichever size system your home needs. They need to start by measuring external static pressure (ESP) while the system is running. If nobody within the company you are considering has the ability or knowledge to do this, that is a red flag and they are throwing larger equipment on inadequate duct systems. This is bad and affects performance. You lived with it for a while; then they put what I would consider a "bandaid" fix on it with the oversized condenser and blower to compensate for undersized ducting. The result was more noise and less efficient operation, but more air volume. With your new system, I would hope the dealer you select works toward providing you with a quiet and more efficient system. Good luck and please keep us posted.
