AC Cools But Doesn’t Cool Well All The Time

Saturday, July 23rd, 2022

Hi welcome to the #1 Katy Texas Air Conditioning Blog. This topic can be quite confusing at times because your air conditioner works by science not by magic.

The terms I use here are going to be terms that anyone should be able to understand. I remove as much technical jargon as I can to convey this subject so more people can understand it. (It’s not about writing it so I understand it.)

Air Conditioning Removes Heat

So the reason behind this post is that when record breaking temps come to town most air conditioners are going to struggle. It is completely normal for your thermostat temperature to go up in the afternoon under a heavy heat load.

With that said, this AC activity can point to trouble as well. Many people when they see this they think the thermostat is bad, their AC unit isn’t big enough, I might need some Freon and a laundry list of other potential guesses.

Air Conditioning doesn’t produce cool. It removes heat and the absence of heat is a cooling effect. That is what I mean by science. There are limits just as much as anything else. Trying running 50 miles with no breaks, to understand the point. Try driving your car with no gas or no electric if an EV. Everything has limits. But when it comes to air conditioners people repeatedly think they can put that thermostat dial anywhere and get it to get there.

Freon from above means refrigerant. This substance is more or less a solvent that was specifically designed for your air conditioner to remove heat from the structure. It is important that your system has the right type of refrigerant as well as the proper level. Too much or too little and your AC system will not remove heat properly and in triple digit heat (outdoor ambient temperature) will be costly to operate not to mention may not provide the cooling effect you are looking for.

Air Conditioners Don’t Use Up Freon

An Air Conditioner is a completely sealed system. The Freon in your AC will last indefinitely, unless the system has a refrigerant leak. Improper maintenance or service procedures can introduce leaks as well as age of the system can create refrigerant leaks over time. The older the equipment is, the more likely that the equipment is to blame.

However, just because your AC unit isn’t that old doesn’t necessarily mean it is free of refrigerant leaks. Air Conditioners are machines, and machines break – old and new alike.

Freon Leak Sealers / Additives To Stop Freon Leaks

I’ve used a couple of these over the past few years, but I have found they simply do not work. My definition of working is that they fix the refrigerant leaks. If they don’t do that, what is the point?

My opinion is that adding a Freon leak sealer to a system is attempting to take a short cut rather than to fix something the right way because the right way costs more money.

But if the refrigerant leak is not fixed, it will cost you more money anyway because the costly refrigerant will continue to leak out. The other less thought of problem with leak sealers is that you are placing something into your AC refrigerant system that does not belong there. This could lead to other problems later.

Watch the embedded video below how to properly fix Freon Leaks and stay tuned to just how well a leak sealer worked in a test I performed.

Substances Not Condensing In An AC System

A refrigeration system is critical to be a clean environment free from things that contaminate the system. The AC system is a sealed system remember? So if contamination is introduced the system isn’t going to work properly.

This problem is more so magnified in a record breaking heat wave. Your AC system’s operation is dependant on having the proper refrigerant, the proper amount with every thing fluidly moving about. If too much refrigerant is placed in your AC system it won’t work just as much as if it has too little of refrigerant or the wrong type. Freon is merely a brand name. I know what type your AC system needs, but I don’t know the service history if you call me for the first time. If a refrigerant circuit in your AC is blocked up it’s not going to work properly in triple digit heat.

Air is a common ingredient that will not condense in a refrigeration system. This only gets inside your refrigeration system by someone not doing something they should have done. Putting a leak sealer in the system could do essentially the same thing. The common reason people do this is that the system is older and will at times say I have nothing to lose.

Then replace the system a few years later, reuse the line set that possibly has some of this contamination left behind. It can be quite difficult to replace line sets on some homes and that difficulty can add a good sum of money to do so.

Did you know that the refrigerant in your AC system goes thru phase changes in side your AC’s refrigeration circuits? This is necessary because the pump otherwise known as the compressor is a vapor pump. Trying to compress anything other than refrigerant vapor will damage the compressor. If that happens? YIKES, not good.

But your AC’s refrigerant system also contains refrigerant in liquid form. Without that it simply will not work. It’s not magic, remember?

Your Air Conditioner Is Doing All It Can

This could be true, just as much as it could be false. Just because you dial in 70F on your thermostat doesn’t mean your house will get that cool in triple digit heat (100F and up – we’ve been hitting 102 and hotter recently in the Katy, Texas area.)

Design temperature plays a role. In our climate in Katy, Texas design for this area is 75F inside with 95F outside. These are design parameters. Does this mean you will never get lower than 75F inside? No. The heat of the day or the hottest part of the day is typically 3pm-7pm or 3pm-8pm during unusually hot record breaking periods.

These events as well as the condition of your AC system, your home’s thermal envelope conditions, duct work, system design and how you operate the system can all have an effect (good or bad) as to how hot or cool your house is.

A Not So Cool Story

Part of the reason for this blog post. I recently ran an AC service call in which the home in question was a rental house. The tenant recently moved in and not accustomed to the Katy, Texas climate just yet… or so this is what was relayed to me. I only know what you tell me, the rest is nothing more than a series of guesses.

I have never been to this house before. So I have no service history to go off of. I am walking blind so to speak. The system had recently been repaired, part of the AC system was replaced by another HVAC company. (Single story home, one HVAC system)

I get there (to the rental house) and the thermostat is reading 72F with nearly 100F outside. So on face value you could say this air conditioner is doing all it can. Essentially that would be true. But that unfortunately doesn’t go far enough.

Because taking AC service readings into consideration points to a bigger problem that only gets bigger the further I dig. It didn’t take long because this job wasn’t mine I was only there to “check out the work” that was done by another company.

Why was that necessary?

Because the other company had been out there a couple of times already saying the AC system is doing all it can do. The home owner decided to do the right thing and investigate further at additional cost. Not doing so could eventually turn into a revolving door of tenants moving in and out. That is costly in the home rental business. I know because I also own a rental house. Experience is worth what these days?

The ramifications of what I found? Split temperature / Differential Temperature / Temperature Drop / Delta T. What ever you wish to call it… was 12F. This should be 15-20F degrees. Preferably the closer to 20 the better for our climate here in Katy, Texas. Because as our design parameters describe you should have closer to a 20 degree temperature drop across the coil. Although any thing above 15F would be considered a passing grade.

So just that test alone I expected the AC system to be low on refrigerant. But that is not what I found. Because I don’t have any past service history I am led to guess what may or may not have happened here. (Contaminated System / Improper methods / Some other issue not yet known)

This is also to suggest you can’t just go with what you think the problem might be. As adding refrigerant to this system would only make things worse. Removing refrigerant won’t help either. The difference from proper to improper. Living with it? I suppose you could live on the edge but additional failures on your dime? Remember Katy, Texas is a hot climate. We separate the men from the boys in this climate on a fairly consistent basis when hitting triple digit temps. Not to brag, but I know what works, I also know what won’t work. So because I am not the installing HVAC contractor I can only guess what they did do as well as what they didn’t do but should have.

Guessing is not only dangerous but also costly. This customer ( home owner of this rental) has used me for work before. This wasn’t a free call – my opinions are worth paying for I am not nor have I ever been a gimmick provider. Service history is what determines what costs may be for me having to go behind someone else.

There is no warranty for improperly installed equipment. Currently the home owner had decided to get this company to go back and fix this system. The excuse this other company has been using isn’t going to fly now. The tenant is by now relieved that they’re no longer considered ‘nuts’ or making stuff up.

The AC Is Doing All It Can

When you’ve been doing HVAC Repair & Service for as long as I have you get the opportunity to see it all. I don’t just work on rentals, but this story is yet another rental. These stories provide unique insight to this AC blog post topic.

I think the reason for these kinds of stories is that tenants will push HVAC systems quite hard. This particular system has two floors with one system and thermostat on the top floor.

So this story goes to places the other call could only dream of. I have service history of this address so I know the complaint is likely bogus before I even get there. But I still have to “check it” because if you don’t you’re guessing and guessing doesn’t work in HVAC. I have a reputation of telling it like it is. Not going to stop now even if I think you can’t handle it. At some point you’ll have to put on big boy or big girl pants just like I do every morning.

I get there I have a conversation with the tenant and they claim to have to blast the AC at night so the room on the lower level doesn’t get too hot. Also that in the after noon the temps rise on the thermostat on the second floor. Which is normal by the way in triple digit heat.

Upon checking the unit while I was discussing things with the tenant on first floor the AC cycled off. I began this check with room temp on top floor at 69F at the thermostat.

In order to check this AC system I dropped the temperature to 65F to force it to run so I could perform the check. The Delta T / Temp Drop across the coil was 22F. This particular AC was installed by me. I have been servicing this property for a number of years.

Notice the difference in Temp drop from the first one? 10F better.

Operating Pressures? Outstanding. (These fluctuate so it’s pointless posting this information.)

Because of the nature of a tenant occupant I even recorded the temperature in the master bedroom suite on the lower floor. 65F — yet design is 75F. So you can see how these things can vary from one home to the next. No two homes are alike.

Everyone’s view of what comfort is can and will be different from other viewpoints. But design is the limit. This particular property has a control on the top floor with one HVAC system so it will always be warmer on the top floor. (Heat rises)

And the thermostat on the top floor does not now how hot or cool it is on the lower level. These design flaws can be fixed. But that costs money.

The HVAC Comfort Business

HVAC is a big box of comfort. Service is part of that, just as much as design and all these other factors. The HVAC product & design you choose has limitations. It doesn’t work by magic and your definition of work should mean more than “The unit turns on, The unit turns off”

Because there is more to it than just turning on or off. It must be doing so properly and efficiently. What is properly to someone who doesn’t know?

I thank you for visiting with me today. I hope this subject may help you garner more understanding in relation to how you view comfort the choices you make for those that provide it for you.

As always I hope your day is comfortable.

Air Conditioner Was Recently Installed By Other AC Company And It Is Noisy When It Starts Up

Friday, July 8th, 2022

Quote from Website contact form:

Hi there… I bought a Armstrong Air A/C about a year ago from a friend. From the get-go, when the unit starts up (upon engagement) there’s a loud boom.

I called him (the friend) about three months ago and he installed a hard start device on it. At first, it seemed to quiet the unit a bit but 95% of the time when it starts up it sounds like a shotgun going off.

I contacted Armstrong Air Corp office. All they said basically was to get an A/C guy out to examine it. I don’t see how this units life span will be long, plus it’s loud as heck. Any suggestions? Thank you XXXX.

End Quote.

So I called this guy (the home owner) and we had a lengthy discussion over the phone when it was convenient for me because of ‘time’ which is money in it’s most valuable form.  Service isn’t free, time isn’t free and my labor cost doesn’t come from a manufacturer warranty.

The round about way this conversation went from the start is that he (the home owner) needed to get his friend (the person who installed this machine) to fix the problem. That was my suggestion.

He (the home owner) tells me this guy is no longer his friend.

The home owner paid friend for a product / service he didn’t get. Either the friend does the job he was paid to do OR…….. read on.

HVAC Repair Service Katy Texas Choices

 

You have choices, but if it’s going to involve me it’s going to cost you money. You can ask for suggestions via my contact form but 9 times out of 10 you’re not going to like what I have to say. I may offer you more than one option, each with it’s own set of risks. I am a AC repair man first, if it breaks again? I can probably fix it again under the same set of conditions as before. HVAC repair is my business in Katy, Texas.

It is better for you if you haven’t conflicted yourself with another HVAC contractor. The HVAC industry is changing as it occasionally does and sometimes it changes in ways that are not beneficial to you when you’ve put your trust in a company that doesn’t stand behind the equipment they installed for you.

Noise is a complicated subject for a system that I have not inspected. This person was at the time I talked to him looking for a ‘simple’ fix. If this AC only needed a simple fix why didn’t his friend fix it? This circular logic isn’t to degrade anyone it is to offer clarity to the gravity of this particular situation. I warned him in advance that it didn’t sound to me like a simple fix is in his future.

I have installed numerous different air conditioning brands over the years and never once have I been faced with what is likely a compressor sounding like a shot gun blast every time it starts up.

I have no idea what was done when this unit was installed, let alone what was not done that should have been. So because of this it represents a ‘conflict of interest’ for me to become involved in it EXCEPT, that the home owner is willing to pay for whatever solution I offer to correct the issue. The manufacturer doesn’t pay for anything they merely provide a part with even more conditions in some situations.

I wasn’t the installing HVAC contractor to this unit, that is the job of the installing contractor to make this problem right on a AC unit that is about 1 year old as far as I know.

One such solution would be to replace the offending part of the system. The part that is making all the noise. But it’s a new 1 year old AC unit? If I were to replace this compressor under part warranty and the manufacturer determined later this part failure was due to something improper at installation, the manufacturer would have every right to deny the warranty of that compressor.

I then face the risk of being charged for this compressor when it wasn’t my job from the get go. So you understand why this is a conflict of interest. At least I hope you understand.

You have to realize I am here to do things right. It’s a trade mark within my logo. *Done Right*

If I installed the HVAC machine, some of it, part of it and it develops some problem like this I am going to stand behind it and correct it. I spell out what is covered on a warranty and what isn’t. In some unusual cases it *may* cost some money to repair the problem depending largely what is wrong with it and what is involved in fixing it / how long it took for the problem to occur.

There are limitations to every warranty. My job to fulfill a warranty is to ‘make you whole’ when I was the installing HVAC contractor. However, this doesn’t always mean it will be a free repair. Labor, Maintenance, power surges, rodents, refrigerants, equipment use to repair problems are not covered by any manufacturer warranty. Exception: labor is typically covered for 1 year by the installing contractor. Anything above that and you pay for it up front, but that will also come with additional requirements such as prepaid maintenance contracts to maintain the equipment. If those maintenance appointments are not performed, that extended labor warranty won’t be worth the paper it’s printed on.

What I spell out here is fact (truth). If you want a gimmick, you’re not going to find it here.

Refrigerants (Freon)

The refrigerant your system uses R410a has shot up in the realm of 325-340% since a year ago. (2022) Manufacturers do not cover refrigerant, even if I am replacing a compressor under a warranty for a unit that I am not responsible for. No I am not going to reuse the refrigerant in your current system because that refrigerant could be the cause of what is wrong with the system, or lead to that cause.

Does this mean I am not compassionate? No. I understand this home owner paid for a product and he didn’t get what he paid for.

If I have said it once, I’ve said it a thousand times that the installation of the AC unit is the most important part. It’s not just what you know, it’s also what you should know but don’t realize.

Sharing is caring. I share this subject freely to help you the home owner make wiser decisions. I give you choices. Currently this home owner has decided to do nothing, because he paid for a product & service he didn’t get from a different HVAC contractor.

If he decides to later use my services to correct this problem, I’m almost certainly likely to include this subject on an upcoming video on my YouTube Channel. 

I gave him (the home owner) a choice, pay more money to me to investigate with a full fledge warning in advance based on my experience of 28 years that likely what I recommend to him isn’t going to be something he will like monetarily.

If Austin Air Companie is going to do some work for you, that work is something I am going to stand behind. Does that mean there will never be any more additional cost? No. I am well aware of the gimmicks floating around out there.

If they aren’t gimmicks there wouldn’t have been any need for this home owner to contact me this way.

Thank you for visiting with me today. I hope at the very least this AC blog post has offered some clarity and the importance of who you choose to maintain, service, repair & replace your home HVAC system.

As always I hope your day is comfortable.

Did you know that HVAC is often times a game of cat and mouse? You see early on in my HVAC career I was forced to run calls for free. Because the managers / owners of the company I worked for were into games of tricking people. The advertisements were geared toward making the phone ring (promising free this or that). Then to make those advertisements pay off I was told to sell new HVAC systems. You have to do that to pay for those fancy advertisements from the TV. In 2022 advertising costs are even higher not to mention the cost of everything else.

If you are calling me I will inform you of all choices after inspecting your HVAC system(s) even repairing your air conditioner if that option makes sense. I am skilled in working for you, not just recommending something that is only beneficial to me. It’s about providing you an air conditioning service that you can rely on. I will do my best to explain the risks of doing what you decide to do. That is what a skilled HVAC contractor can do for you.

If I ran service calls for free now with gas prices where they are up over $4 a gallon currently (2022). That isn’t wise financially. I have to remain in business to serve the customers I have already. As I lay out things that are changing in the HVAC industry in this Katy Texas AC Blog post you need a skilled HVAC contractor more than ever. Unless of course you are naturally wealthy and can afford to replace your AC equipment over and over again.

The choice is yours to make. I lay it out for you then you choose what you think is best for you and your situation. If something else happens? Call me again. You will always need a good HVAC repair man, more so now than any other time before.

Anyone can say anything on the internet. I am well aware of that so I provide you some proof below that I can silence your air conditioning noise. The unit in the video below was much older. I was called out long after it had started making all kinds of racket. The unit shown in the below video made this racket for years, until it finally gave up the battle on a very hot summer day a few years ago….

Watch me fix the noisy Air Conditioner in the video below. I’ve been out to this house several times since this unit was fixed, repairing other parts of this HVAC system. The unit is still as quiet as it was the day I installed it.

You will always need a good HVAC repair man.
