spray the coils with non-acid based coil cleaner, let it soak in for a few mintues, then rinse and repeat if needed. the water and cleaner goes out the drain. you should see 1 drain line coming off teh housing itself, then a second back up drain line coming off teh drip pan below the housing. both of these should be kept cleaned out, pour some bleach down them 1-2x a year. if your unit has the filter in the airhandler, then pour some bleach down the drains each time you are up there to change the filter. BTW, if the coil is extremely nasty you may require a pro to do the cleaning. they will have to evacuate the system, remvoe the coil, clean it, then reinstall and recharge it. NOT cheap, but is necessary in many cases.

Condensation from the freon lines is normally channeled to a plastic drip pan where it evaporates, with the help of the heat given off by the compressor motor. If that channeling is disrupted (by that metal tape?) the condensation may end up on the floor or where it will cause metal to rust.

Do you like the Amana they are proposing, they also have a 14 Seer Rheem as the cheapest model --- The Rheem is a basic single stage unit. I am trying to find out the model number on the Amana but I think it is ASZC16. I had to ask what they were selling me because they have some agreement to use the HVAC company name in model description: XXX TruComfort Signature Series Heat Pump (dual speed) XXX TruComfort Pro Series Air Handler Variable Speed Blower. XXX is HVAC company name The rep said Amana was "allowing" them to use their name. Ah, OK a couple of things... There is nothing wrong with Amana. I've installed it many times. Rheem units I've repaired many times nothing really wrong with those either. Most of this comes down to how well you take care of it. Who installed it, how they installed it and so on. I have installed over 8 different brands of HVAC equipment. Not to brag but to tell you brands don't make much difference... when you know what you are doing. Most people don't realize what I say here, most of what manufacturer's do is a mirror room of competing brands all of them made by 7-8 manufacturing companies. So the most important in my eyes is: buying the model that has the options you want, lowers utility bills, keeps you comfortable etc. The more options you buy the more it will cost. The Amana ASZC16 is a 2 speed heat pump. The lowest 2 speed you can buy. Not a bad unit, but not as efficient as say the AVZC20 which is the Amana 20 SEER inverter heat pump. I put in an inverter heat pump at my home last year, I didn't choose the Amana. I went with the Bosch 1.0 18 SEER inverter heat pump. This can and will throw some for a loop why I often sell Amana but went with the Bosch. I have sold the Bosch to others as well. It's knowing and understanding how these things operate. So to keep this short all I am going to say is it was a choice based on what both do, how they do it AND the cost involved to pull it off. Their are risks in using the Bosch that aren't there with the Amana brand. So it's a choice is what it is. Now in terms of a Company True Comfort xxx air conditioning made by so and so... They can do this because they move a LOT of equipment. Probably in the 100's of thousands of dollars a year. Carrier upset this gravy train by getting too greedy most likely and this company shopped around while waving a cash stack, ready to buy a lot of equipment. It's really no different when Kenmore sold their branded AC back in the day made by none other than Carrier ironically. The reason companies do this is only they can sell you a 'True Comfort' so and so. You know if brand is so important to you and nothing else is. That's why you need to avoid the 'my brand is better than your brand' they all break. Going with a bigger company has it's plusses but also it's negatives. The negatives revolve around the feel like another number to the company. Most of my customers are on a first name basis with me. I am the only one they ever see. So many ways to do something as you can see here.

What is happening in 2023? R22 has been in phase out mode for well over 12 years now. The current refrigerant that replaced R22 known as R410a is going to be phased out. California enters this phase first. No new R410a installations in CA starting in 2023. R410a begins it's phase out with strict rules than the aformentioned R22 Freon. (no dry units like with R22). Texas is likely to enter this realm in 2025 at the latest. The refrigerants replacing R410a isn't much better than that of R410a. Two competing versions R32 & R454b both of which are mildly flammable. How flammable? mildly. If you choose R32 solution, that is likely to be phase out sooner because it is mildly more offending than R454b. But either of these choices shelf lifes will be short. Maybe 15 years, maybe 20. R22 is cost prohibitive now. If you have a unit that uses R22 --9 times out of 10-- and you spring a leak -- you buy a R410a unit now. Because? The new units have yet to arrive! ( this is assuming you can even find what you want now.) So in short order anything you buy now will essentially be obsolete "over night". This primarily will only effect you if you spring a refrigerant leak. BUT, refrigerant leaks nowadays are more common than 20 years ago. If you're curious what, where, how and why this is happening? I made a video about it embedded below for your convenience. Note: this video is only a starting point... Part 1.
