Why Can’t My Air Conditioning System Keep Up When It’s Hot?

We’ll start off today’s blog with a bit of AC trivia: the first completely air conditioned home was built right here in Minneapolis. It was a mansion for millionaire Charles Gate, heir to the barbed wire fortune. But Mr. Gates never go to enjoy his cooled home, since he died in a hunting accident before construction was complete.

On to more immediate concerns… when your air conditioning system isn’t able to keep up with your demands for cooling.

There are a number of reasons why an AC might start to struggle with the summer heat, and most of them will require work from air conditioning repair professionals to correct. Below are some of the possible causes for an AC that can’t keep up:

  • Damaged ductwork: The problem may not be an issue within the cooling system, but the ventilation system. If your ducts have air leaks in them, it will raise the temperature of the air inside, and that means less cool air around your home. You can call on our home performance specialist for duct sealing to solve this problem.
  • Loss of refrigerant: An air conditioner is supposed to run on a set amount of refrigerant, called its charge. But refrigerant can leak from the system, and this will cut into its cooling power. It will eventually lead to damage to the compressor, so don’t delay when calling for repairs!
  • Miscalibrated thermostat: Something small like the thermostat can actually have a large impact on the effectiveness of the HVAC system. If your home’s thermostat is reading incorrect temperatures, it will turn the AC on and off at the wrong times, which will result in a house that’s too hot. (Or, in some cases, too cold.)
  • Undersized AC: Is your air conditioner a recent installation? Then the problem might be that it’s not powerful enough to keep up with your demands. This is one of the reasons to always call on experienced professionals for installation, since they have the knowledged and training to see that you have a correctly sized system.

Brad was the lead tech on installing my AC/furnace on May 28, 2024. He was outstanding. Very kind and personable. I couldn’t ask for a better final install. Brad was AMAZING! Thank you so much for a fantastic job.

Alec, our technician for this semiannual maintenance check was great! He checked everything thoroughly, documented everything for us, and made a couple of recommendations with no pressure. He also took the time to thoroughly clean the leaves out of our outside AC unit. None of the technicians before him have ever taken the time to do this for us. Extremely impressed with Alec, and his quality workmanship and work ethic. Thanks again Alec!!!

The people are incredibly nice. But their prices are insane, they probably give you the best product and best service but you'll pay double for a lot of their services. I also can't recommend their ac/ furnace tune up because it's an absolute rip off. The "6- month guarantee" just means they'll come out for free if your system breaks down in 6 months, that's certainly not worth $250 when even a high end tune up costs about $100 and most go on sales for $50.

My water heater went out 430 pm on Wed, called Aquarius, they had a tech out the next day to replace it! Fortunately they had already quoted a new one. The A Team, Adam and Andrew had it replaced in no time, found a small plumbing problem fixed it and helped me by taking some scrap metal back to the shop for disposal! We will always call Aquarius first!

Mike did an EXCELLENT job! I have a very old AC unit and I can’t afford to replace it. I was concerned I had caused the AC to not work when I cleaned it off with a garden hose. He assured me that I didn’t cause it; it was just time for the parts to be replaced. He showed me what he replaced and explained where/how each part failed. I have called on Aquarius Home Service for many things in the last three years and will continue to be a loyal customer. I have referred them to others, as well. I highly recommend!

Our water heater went out on Fri evening. We called Aquarius early Sat morning and they said earliest they could get out was Mon. On Sun I received a text confirming our Mon appointment but on Mon morning they called and said the earliest they could get to us was the following week !We should be without hot water till then ? We are not a new customer…. 5 months previously we had a new furnace and air conditioner installed at quite an expense. I am appalled at their service or rather lack there of ! As an established customer they felt waiting approximately 10days without water was acceptable Bad, Bad, Bad !

We have had Aquarius out for several jobs and they have done an outstanding job. This was with Paul and AJ for some exterior electrical work. Installed a fan on our covered porch and two additional outlets. Paul thought of going through the attic to install the fan so we did not need to have any exterior conduit showing. We will definitely have them out as our service needs dictate.

We had an excellent experience with Aquarius. Our plumber, Erik, was efficient and thorough. He made a complete assessment and gave me different options for the repairs I could make. He also prepared me for the costs of the repairs we knew we needed to make now as well as the repairs we will likely need to make in the future. I felt like I was able to make a good choice about what needed to be done today, and I’m ready for what to expect in the coming years as we care for and repair the 75-year-old house we love so much. I will absolutely use them again.

Had a very good experience with our plumbing needs as our service technician Gordy was very knowledgeable and provided solutions for our plumbing issue. Gordy also identified a couple of potential future issues and provided options and bids for those as well.I would recommend Aquarius Home Services to others based on my personal experience
