AC Not KEEPING Up!

Joshua goes over multiple reasons an AC may not be keeping up or is taking longer to cool your home. Air conditioning in a home is different than in a car and there may be reasons your AC doesn't keep up like it used to. He also discusses HVAC products meant to assist your AC and help it perform better when cooling your home.

Living in central GA it's just plain HOT and humid in the summer. I run a window unit as well. it helps alot with the central AC not having to work as hard.

Change your filter and get your system serviced. Make sure the tech runs a static pressure test. At least 70% of homes in my area have high static pressure and a 2nd return air duct is almost always needed. High static pressure means bad airflow in the house. Also, in summer keep your home from getting hot by keeping the AC on and running all day long!! Turn it on in the morning, even if everyone is leaving for work. It's a whole lot easier to keep your house at the desired temperature.

A factor I’ve discovered that greatly helps HVACs. A ceiling fan. But running on low not high. I think inclination is to set the ceiling fan on high. I find that pushes cold air to the corners of the room, not achieving circulation. Low speeds gently circulates the cold air. I have mini split ceiling units. One of my rooms had the AC set to 63. The reason for the low setting was it was hot. But I noticed the ceiling fan was on high and that despite running for over 30 mins, the room temp never went below 70. I raised the AC Temp to 66, lowered the ceiling fan to low. Within 5 mins temp started dropping/cooling. Within 30 mins room was, and remained at 66.

Had a J-Calc done, and the recommendation is to upsize all lines and address an aggressive bend at the rear of the home. It’s been over 100 degrees for many days in MS. The system usually works until you get above 92 degrees outside by noon. As the day progresses the interior of the home can ramp up from 74 to 77 degrees on the thermostat, and the unit runs nonstop from noon to 9 pm.
Was quoted 6K, and would rather not finance. I’m thinking about getting a window unit like my grandparents used to until I save up.

I’m in FL, bought an 86’ 3 years ago and the ac was 5 years old. Haven’t had it serviced but I do clean the condenser and change the filter every 30 days. Over the last couple months my ac just runs day. Temp is set at 76 but the thermostat reads 77-78 though the day. Use to be able to set it at 74 and it would hit that not problem

We added a mini split this heat In Louisiana is deadly

Got to size your A/C to the load factors also. My house is under-sized for the sun exposure it gets, the lack of insulation between the thermal mass of the brick walls, and window leaks. To right size you need to run the ASHRE calculations, and many HVAC people won't do them, because it's kinda complex and time-consuming to figure out how much cooling capacity you really need for a building.

Great video. I really appreciate your desire to help people understand the basics instead of just trying to sell them something. I wish you and your business great success.

For the first time in awhile our Houston area humidity dropped down to 35% and we had to adjust thermostats for comfort. Save on electric bill. JG you're always spot on!

My home is 900sqft. My unit is 15 years old. I'm in Florida. I get my unit serviced twice a year and do my best to change to my filter monthly. I also pour a cup of white vinegar in the unit when I'm changing to filter...ac tech told me to do this. The AC unit will cool air to 74 when it's 100 outside and then all of a sudden will stop cooling air and the house will get to 79. The ac unit sounds like it's on but i do not feel any cool air coming out. Had the ac tech come out. He had no idea what was wrong with it. Decided to flush the drain. He says that alot of sludge came out. The AC worked well for half that day and then stopped working the next day worked for a little and then stopped cooling and so on. It has been 5 days now. Any suggestions on what it could be. I trust the ac company. It's a family owned business that has been around for decades, .but something is wrong. Thank you!

like you said my central cooling system never blow cold air blow the 60-64 but i installed mini spilite 2 tons Dakins this summer its not make different for the unit if outside its 108 and inside house is like 85 it is blow 49-50 cool air all the time which its awesome and now i just run my mini spilite unit .

[sykotictendencies]

Also air infiltration is a huge factor. Not enough insulation leaking windows and doors and like you said attic ventilation all has a huge factor in all this .

Interesting thoughts. The misting idea would be a good plan for those in desert heat areas however, depending on the hardness of the local water there, might be best to use distilled water to prevent scale build up on the "fins" etc. Good disclosure to the public about "everything holds heat inside the house" such as the furniture, appliances and other physical items. I always tell folks that its about the same as a hot baked potato out of the oven. Think of it that way...at some point the amount of BTU's or heat they absorb when they turn the temp upward and go to work is way more than they would think and when returning home or when the set back temps turn on again, the A/C has to remove all of that heat before it will cycle normally. Depending on the home age and energy upgrades, leaving the A/C on 24x7 all summer may cost less than going through heat cycles every day. Those who set their temps below 76 in hot weather are simply using maximum A/C and electricity as well so they shouldn't be complaining about power usage.
We have high power rates in our town, 38 cents per kWh ! That's about 5 times higher than most and when its hot outside, we pay through the nose for power that comes from the same places anyone else gets. $675 a month in summer when most are paying $150 (1, 800 kWh). But, its not bad enough to warrant an expensive 26 SEER system yet as its only 3 to 4 months a year. Now that the nations Government seems to think banning natural gas is a great idea and using heat pumps in areas that reach 115 in summer and 30 every winter, the cost for energy will easily increase due to the increase in power usage during winter and less efficiency in peak summer and winter times. What a complete cluster Newsom & Biden have made. We have our Government telling us how to heat and cool our own homes.

I’m at a loss right now. My ac has a very hard time bringing the temp down. It’s a newer unit and the delta is always around 20 to 22 degrees. But during the day I can’t lower it past 80 and at night I can’t get it below 75 some nights. I just added attic insulation and it’s made a small difference but not much. My windows are brand new double pane. The only other thing I can think of is maybe there’s an air leak.

[wrydrune]

Here in Florida we hit 97 (112) the other day. My ac is only about 3-4 years old and it got 84 in my house, even with blackouts.

I live in a 2 bedroom apartment, going on 6 months living here. For the light bill and it was $438. Had the maintenance guy come and check it out bc it keeps making a metal thumping or clanking sound when it kicks off and on. He said is normal for it to make that sound and that it's a new unit that's up in the attic. Excuse me, I've lived in many apartments and I've never heard an ac unit do that. He told me to just shut off during tye day and get black out curtains and have them closed all day and night. Uh... wait what? You wave me to live in the dark and have my ac off??? Ok, i wanted to see what would happen. It's midnight and it's 79 outside. Turned tge ac on at 6 and set it for 70. Temp inside read 81. It took 7 HOURS for it to go 81 to 76, 7 HOURS and it isn't at 70 so I set it for 73, still at 76 and still running!!! This can't be normal or is it??? I've complained about this and they keep telling me it's normal and nothings wrong with it. These apartments are 20 years old. My friends who live in houses say that's crazy bc their houses are bigger then my apartment and their light bill doesn't go past $260. I'm thinking about calling the city inspector. Any advice or thoughts on why the ac unit is taking hours to get to 70 or 73? Help, someone please. Ac still running trying to get to 73 and i don't know it'll be at when i wake up.

I’m in Virginia down 64 from you, and the house envelope is the biggest issue here, but duct work issues will also cause high temps, if the tech is doing his job right and the installer, you don’t need to oversize and add a dehu, the ac will dehumidifi perfectly. If your duct and and ac is setup properly for it

[publicmail]

Dont forget when very humid DT may be down to 15F vs 20F.

[vrfrir]

No mention of checking your liquid lines insulation inside or outside? Some attic installs have liquid lines not sealed properly at all or the outside ones are almost completely rotted away and in direct sunlight all day, basic stuff

[Balticblue]

It makes me laugh every time I hear dehumidifier on an HVAC system. In Colorado, we had humidifiers to our HVAC systems because we live in the desert and everyone thinks it is all snowy and rainy. 330 days of sunshine and 10% humidity on a good day. They adjust our equipment to naturally add more humidity during the AC cycles. We do backflips, if we can get 35%-38%. Enjoy watching your channel and have learned quite a bit. I am HVAC school and your input gives me good things to study and learn.
