I went through this same issue on a property first company air handler leaking like crazy, but they were several years old, so previous maintenance before me, which were people that was on the property from day one just kept charging units. There were some you walk around the building and you find a short hose and a drum just sitting there. Connected to a unit with it running. And this beautiful five bay maintenance building well two of the bays were filled waist deep in refrigerant drums, but basically confined to the last 15 or so feet of each room 3 1/2 feet deep. each drum had a tad of refrigerant. We purchased some new recovery drums and a new recovery Machine. And we started cleaning drums of Freon when we were done we had over 300 pounds of refrigerant stored up in recovery drains that company purchased over 300 drums of refrigerant in just under seven years and no one questioned it so what they were doing was billing to different properties. Not one person had the sense to report it under a warranty when the property wasn’t even a year old for all I know the lawsuits are still tied up today.

[@LexVance]

Crazy! These coils have been nothing but trouble. Every single one is leaking on a 300 unit property.

[@jraydelatorre]

@@LexVance the ones that we were doing had no TXV just two pipes coming down and they were extremely accessible very roomy units. The only thing we had to worry about burning was pipe insulation and we were able to pull away or slide it back. i’ve never purchased or replaced a TXV in my life but I’ve been retired for 10 years now. Most of the properties I worked on were old my newest property opened in 1999 with all Goodman inside and out suite no problems hardly at all

Just had a whole new ac unit installed in my house today, the hvac guys spent about 6 hours doing the work.... The AC DOES NOT WORK ! They did something incorrect in the installation so now they have to return to find out why it is not working. Would have been nice to have a knowlegable HVAC guy like you to do teh installation - instead I got the 4 stooges.

[@Reemer5000]

Was it the installers or the equipment? Just curious because New equipment does arrive DOA all the time. I worked for a major supplier and there were times we would get so many warranty claims for leaky coils. Goodman 4-5t evap coils were notorious for this In recent years. Although the installers do play a small role in when they pick the equipment up, they should pressure tested anyways just to make sure but still.

I went through that property two coils a day we had a three-man system set up where we would pick two units a day recover recycle, replace refill, and the good old topping it off after we were done it was always missing refrigerant. LOL they wanted us to do it in one week to 180 something coils they were 280 units on the property but they were additional coils well you know clubhouse community building, pool area, restrooms and showers weight room, exercise facility, laundry facilities, and there were a few buildings that had enclosed breezeway with elevators. Those areas were climate controlled as well. At least two of them the good old handicap building.

We have had our AC guy out twice, the first time he filled/changed (?) our coolant. 3 gallons or so he said, he came out today again because the AC wasn’t going and the house is at 90. Today he said he installed a run capacitor, but several hours later our home is still at 90.. we are at a loss and not sure what to do. Would you recommend trying a diff company for another opinion, or calling him back out? Thanks for your content! Much love from AZ.

If the company does it for free after messing up the previous diagnosis, I'd stick with same company. A new company will charge you more money. I hope everything works out for you! 🤞

Once saw that i completely turned off the AC unit and my light bill dropped to 60 dollars that month and 65 the next month. What u think the problem could be regarding the AC unit?

[@LexVance]

When they're low on refrigerant, they run for a long time. Causing bill to be high due constantly running.

[@chadburg8700]

Why would you need to turn off the unit to leak detect? wouldn't higher pressures push out a leak faster?

[@LexVance]

The fan would cause interference and suck the refrigerant up. Static pressure is higher on the coil when it's off. Thank you so much for watching!

[@bornbuckeye6046]

So if the refrigerant is low will that make the fan not run? The handler is working but the outside unit is not. When the fan does kick on it sounds weird and is not turning at full speed.

[@LexVance]

Yes, a low pressure switch can make the outside unit not come on. It protects the compressor from burning up.

The refrigerant should never have to be filled up. If it does, that means there's a leak that needs to be fixed because the refrigerant is leaking out. Thank you so much for watching!

got the exact issue bur R22 is expensive and if there is a leak somewhere, what's the point recharging it? your thoughts?

If they can fix the leak, it may buy you a few years to save money for a whole new system. R22 and a leak repair will still be cheaper than $10,000 for a new R410 system.

[@WeekdayWeekend]

My filter went unchanged for way too long. Now, as of 2 days ago, I have very little airflow and my unit has failed to reduce the temperature in my home by even a single degree. I changed the filter, and the problem has not gone away. I'm thinking it's ice buildup? I don't see any ice or condensation on the system inside. The outdoor unit fan runs, and I can hear the indoor fan running just next to where I put in the filter. The insulted line that runs to the outside has condensation on it.

If the tech was right about the motor not working (and i am not sure about that) he could have done the job in one hour, it is not that complicated to replace the motor …he was happy to take $75 …I get the feeling he did not know what exactly was wrong with the ac unit…
