Hi all. So central AC is essentially a foreign concept to me. My unit is 15 years old but seems to be working fine, and I am of the mindset that if it is not broken..... BUT I notice that for example yesterday, I set the unit to 74 degrees. During the heat, it went up to 77 degrees. The house felt fine, but it seemed like the unit was not keeping up? By the evening it went back to 74. I recently had the unit inspected and topped off with the coolant. So I guess the question, is this essentially normal/expected behavior?

You should probably have a reputable company look at the system to ensure it is working correctly.

Our AC/heat pump was putting out 60 degree air yesterday. We set the thermostat to 76 and it had no problem keeping our house cool. That is normal for us but our home is relatively new (<10 years) with good insulation.

Several factors can come into play. If the system isn't working correctly then the system itself might not be getting cool enough. If the filter or coils are dirty then it might not be moving enough air. If the system is undersized then it won't move enough air. If the home isn't sufficiently insulated then regardless of how well the system works it won't be able to keep up with the heat coming in.

A reputable company should be able to tell you if the system is working properly and if the filter and coils are clean. They should also be able to comment on whether the system seems to be sized correctly. We are happy with Munn's though I'm sure there are other companies to choose from.

It could be that it is not large enough to get 74 in yesterday's heat. Since 77 was fine why not use 77?
Up North (runs in the summer) my A/C ran about 15 years. I think at 15 you are getting to the end of its life. Assuming your new A/C will run for 15 years why not get it now instead of in a year or two after it breaks down. My assumption is you will buy a new A/C one more time in your life. So why not now?

Here is a quick test. On a hot day, go to the outside unit and look at the suction line. It is the copper pipe with the black insulation. The pipe should be cold and sweating. If it is, you know that the compressor is working. If not, you may have a cooling issue.

I have been told that the average life in this area is 12 to 15 years. Many may be able to go longer but you may require more maintenance. If it is within your means, I would start getting replacement quotes. Find out the comparative prices, leadtimes, possible rebates and explore the SEER rating which is basically an efficiency measure. Seer ratings have been getting higher with time.

Better now than waiting until it fails.

My AC unit is 13 year old - original equipment. When I moved here 4 years ago, I "purchased" a warranty (pay yearly) from Broward Factory Service. They have free seminars quite often at various restaurants. It covers repairs to A/C units under 5 tons and if they can't repair - replacement. When I signed up - there did not seem to be an issue with age of the unit. I pay them $99 a year to come out and inspect the units. They have had to replace a condenser twice at NO COST to me. The warranty also replaced a leaking hot water tank at no cost. I mention this as why replace a working unit. Other big ticket items are covered too so I suggest you check them out.

Be sure the house does not have one of those "energy saving" gadgets on it that limits your unit at times of high demand (like when its very hot and everyone's AC is running). I had one previously in VA and the house would sometimes get a little warmer as you describe and I can only guess if there were true savings. I'd rather be comfortable.

If the refrigerant was low, you probably have a slow leak. I agree with other posters that you should consider buying a new system. I would also evaluate the size of your current system to make sure it is not undersized. You may need to upgrade to a larger size unit. It may help to compare the size of your unit with other similar size houses in your neighborhood. Typically, you need at least one ton of cooling for every 600 square feet of living space. If you don't know the unit size, write down the model number on the outside unit and look it up on the manufacturer's website. Good luck.

Yep that part I have covered. 2 Ton.
I have scheduled an appointment with home depot to send someone to investigate and size one up. I would like to think I can even get a more efficient unit than a 15 year old system.

Two tons is a pretty small unit. I would get at least 3 quotes for a new system. Two good companies are Munn's and Chuck Farrell. If I needed a new system, I would use Munn's as long as they were reasonably competitive. They are very responsive when you need a warranty repair, even on weekends. A new system will come with at least a 5 year warranty, so you want a responsive contractor. I would not buy a home warranty or separate maintenance agreement.

Chuck Farrell wasn’t taking new customers this year. We have used him for our house since 2012, but had not had him work on our other homes. When I called, even though a current customer they would not make an appointment for our other 2 houses.

In my experience, my 15 year old A/C unit started to do the same. It wasn't broken, and would work just fine in the evenings, but just not able to cool like it used to on the hot summer days. These days equipment is not always readily available...so I opted to replaced it sooner than later. I had to wait a month, but a friend had to wait two months for the new one to arrive.

It sounds like you have the proper size. The courtyard villas in my neighborhood have similar units. The 2 bedroom villas, which are about 1200SF have a 2 ton unit, and the slightly larger 3 bedroom villas have a 2.5 ton unit.

I read this thread with great interest.
Yesterday I noticed when my AC was set at 77, the temp was high at 79 in the house.
I'm having Munn's coming for a checkup in July, so I'll know more then.

I heard nothing but good using Munn's from my neighbors and friends.

They should be able to tell me the life expectancy of my unit.

Our previous home, not florida far cooler, the previous owner put in a far too large through the wall air conditioner unit. Why I never realized or thought to ask.
Our bedroom with the AC on was like a cave cold but damp. It ran too seldom to remove humidity.
The good news is new units have multi speed fans and compressors to achieve better comfort and efficiency. The bad news, parts a expensive and many parts are not standard. A friend, further south than here, had a warranty repair on his new super doper efficiency ac and had to wait TWO WEEKS no AC for then to get a part to do the repair.
What ever happened to standardized parts and a car headlight did your car take the round or the sq ones. Either was $1.99 at Korvetts a now gone along with $1.99 headlamps.

Most of the condenser units (outside unit) installed in The Villages have a single stage compressor and a one speed fan. You can buy a multi-stage compressor, but it is usually not worth the extra cost. The air handler supply fan inside the house has several adjustable speeds.

Chuck Farrell gets excellent reviews. But, another poster said that he is not taking on any new customers, so I tried to call him to ask about it. I called three times today and never got an answer. Last summer, my AC unit failed at 9AM on a Saturday morning. I called Munn's, and they had it fixed by 2PM. I don't know if Chuck Farrell is that responsive. That is why I would probably buy a new Carrier HVAC unit from Munn's, especially since it comes with a 5 year warranty. Chuck Farrell does not do warranty work on Carrier units.

How Cold Should The Air Coming From The AC Be?

high-temperature differential (more than 22℉ difference) indicates one of the following issues:
A dirty air filter
A dirty evaporator coil
Too small ductwork
Incorrectly set fan speed
If this is the case, the first thing to try is replacing your air filter. It is a simple and inexpensive way to fix a Delta T that is too high. If this does not reduce the temperature difference, hire a professional to increase the blower speed of your fan, clean the coil, and inspect your system for other problems.

Ok so first of all Why would you go to Home Depot to get your HVAC analyzed ? Possibly because you want to pay a helluva lot more ? All they do is hire a middleman. Secondly leave your A/C on 74 and see how it does the next day. An air conditioner is only rated to keep your house temp 20 degrees below the outside temperature. It was 97 degrees or so yesterday . Just relax and hopefully make a good decision. I would see if Good guys Hvac could look at it. I think the owner’s name is Michael Labanz 352-247-2484

You are throwing way too many answers at someone who has called Home Depot to fix their problem (which probably isn’t a problem) . Remember we are in some extreme heat compared to the usual 92-93 degrees all summer

My Trane A/C has been going fine for 17 years. It took a little coolant about 5 years ago, but otherwise no problems. We had a 6 month maintenance program with one company for many years until an alarmist tech told us it was doomed to fail - and soon! I called Munns for a second opinion and their tech recommended waiting until it fails. That was 5+ years ago.

My advice: If you are here full time, just wait until it fails. If it is very hot at the time you can easily find a motel during off season until it is replaced.

And I'm not a Scotchman!

Just put in a new Trane 4 ton and it has made a huge difference for cooling. We have a 16-year-old home here in TV and the cooling output from the vents was only 51 degrees at best. With the new system the output reading at the vents is now 44. Cools our 2000 sq foot home down quickly. An unexpected plus is that this new system is about 90 percent quieter.

On your thermostat the anticipator is likely set to three degrees, which seems wide. Usually these allow two degrees variance. That is, you set it to 74, it will turn on at 76, lower temperature to 72, and turn off.

When it's hotter you can raise the temp to 78 and the ac will work better imo. 74 is way too cool and the electric company will tell you that's why blackouts occur. Set it higher and go to a rec center if possible for a few hours. Your electric bill will thank you also!

Also older ac units are not as efficient as new models. When we replaced our 15 yo unit the house cooled better and our bills were less because the new technology was so much better.

You are right about the filter. It’s unlikely that the AC is undersized. It’s also unlikely that it needs to be “topped up.” More insulation might help. Hard to know without checking. Air Conditioners have on off cycles. When they reach the desired temp, they turn off until the thermometer in the thermostat reads that the temp has gone up two or three degrees. Then they turn on the AC again.

Up North (runs in the summer) my A/C ran about 15 years. I think at 15 you are getting to the end of its life. Assuming your new A/C will run for 15 years why not get it now instead of in a year or two after it breaks down. My assumption is you will buy a new A/C one more time in your life. So why not now?

My air conditioning unit was getting old so I went ahead and changed it rather than wait until it gave out. One of the main reasons is I heard that air-conditioning units or heat pumps were going up 25% in the near future.

Before spending money, check to be sure the house air filter is clean. If clogged with dust, then air does not circulate as easily.

My Trane A/C unit was built in 2004 and is now leaking coolant (410A). I called Broward who were kind enough to come out promptly. They topped off the coolant and then quoted me over $10M to replace entire system. No thank you. I ordered on Amazon a product called Nu Calgon Easy Seal Direct Inject to seal the leak. Also bought a 3 Way A/C Diagnostic Manifold Gauge Set to get the sealant into my system. Lastly, am replacing air filter, cleaning the fins on outdoor unit and all the junk on the bottom to improve the efficiency. (How to do all this is on YouTube). I hope to get a few more years out of the unit before replacement. All this for less than $200 and a few hours of my labor is more appealing to me than spending over $10M.

I would suggest that you cancel the Broward contract and get 3 quotes for a new system, which will be far less than the Broward price. I doubt that the leak seal stuff will work.

Good question! I cleaned mine like they said I should do once a yr. It only took about 15 mins. to clean & it did seem to help, but if you’re asking me how do I know it helped, to be honest I can’t really tell other than I know it was dirty because when I hosed out the cleaner it looked pretty muddy looking. My son in Ohio hasn’t never cleaned his & the way it looks neither did the previous owners, but I’m going to clean his when we go there in July!

If you are referring to the outside condensing unit, the fins on the coil are the most important part. If they are dirty, you will lose a lot of heat transfer efficiency. Also, if they are bent, you can buy a "comb" to straighten them. But, cleaning out the dirt at the bottom of the unit will not help much at all.

Totally normal when heat is extremely hot. Heat pump won’t be able to keep totally up. 15 degree difference is normal. It will take out humidity so feel fine. Born and raised in South. Don’t expect ever more than 77/78 in upper 90s or higher. Go to pool or watch favorite old movie You’ll miss the heat this winter. 😉

You say that you recently had the unit inspected and topped off the coolant. If they had to add Freon to the system it means you have a leak some where in the system. The Freon is a closed loop system and you should never need to add Freon unless there is a leak. If it did not take much Freon it would probably mean it is a slow leak.

Consider installing an auxiliary unit. Maybe a window unit or a split. When the primary A/C can't handle the cooling run both. When the primary unit finally crashes, you will be able to keep at least one room cool. This way you can squeeze every bit of life out of your current primary. I agree that around 15 years is normal life around here. But I also know of units that go way, way past 15 years. From 1st contact with A/C contractor to install and startup of new unit can be a week or more. That's a long time in during Florida summers to be without A/C.

Hi all. So central AC is essentially a foreign concept to me. My unit is 15 years old but seems to be working fine, and I am of the mindset that if it is not broken..... BUT I notice that for example yesterday, I set the unit to 74 degrees. During the heat, it went up to 77 degrees. The house felt fine, but it seemed like the unit was not keeping up? By the evening it went back to 74. I recently had the unit inspected and topped off with the coolant. So I guess the question, is this essentially normal/expected behavior?

OPINION MINE-The unit is sized to at max be able to reduce temperature by so many degrees. If, it is say 100 outside and you set your thermostat to 77 it likely cannot do that. Interesting, ac units are rated in tons. One ton AC has the cooling capacity of one ton of ice.

A too large AC will run less and thus leave the air cool but will not remove the humidity,
you end up with damp cool like a cave.

We use our AC a lot. If a heat pump as many of us have, including me, it runs all year
running one way to cool and n reverse to heat. Most everything has an expected life.
You buy a bulb and it says average life. No one tracks it, I may be wrong in that, but you, I expect around that. An ac in the villages lasts about 14 years some more some less. I buy spare bulbs, not expensive. Your AC time to be prepared. Replace it while it is still working. A decision to be made. The seer # is the efficiency number. Did it ever produce that laboratory number-few check or even know how to check. It is very doubtful your old unit is as efficient as it was and newer units are likely more efficient
so will save you on your electric bill.

Consider installing an auxiliary unit. Maybe a window unit or a split. When the primary A/C can't handle the cooling run both. When the primary unit finally crashes, you will be able to keep at least one room cool. This way you can squeeze every bit of life out of your current primary.

A wise solution. I've not looked but a small window AC is like $150. They are not very heavy. Teasing a little BUT I think even with my busted back I can show my wife how to put it in.

Better check with ARC. I don't think window units are allowed.

From the External Deed Restrictions for CDD 10:

Air Conditioners – Window air conditioners are prohibited and only central air are permitted.

Of course, different CDDs have different restrictions.

I agree with the post #22. You NEED to call Good Guy A/C. They are a relatively new A/C company here in the Villages. This company runs circles around the BIG Companies that most people call when they are having problems. He will diagnose your unit and have you up and running 100% in no time. Owned and operated by Michael Labanz. Very knowledgeable in the A/C world. Prompt and reasonably priced. (352) 805-0035

That poses a question. Do I need to contact the CDD to replace the unit? Especially since it s going in the same spot?

A 15 year old system in the south should have been replaced 2 or 3 years ago. You are living on borrowed time.
