Is it normal for AC to run all day in 100 degree weather?

It’s still officially only Spring, but crazy hot temperatures are here putting stress on you and your a/c system. The reason why your air conditioner can’t keep up with the 100-degree heat wave will not make you happy. It simply is NOT designed to. We have received dozens of calls from homeowners frustrated with their a/c’s limited capacity to keep up with the heat outside.

Your a/c is not designed for 100 degrees. There is likely nothing wrong with your system. While it seems abnormal for your house to be 77 degrees when it’s set for 71, the sustained high temperature outside is also abnormal. Your a/c is sized for what the temperature is most likely to be in the summer with the high 80’s to low 90’s being the norm for our area. Your a/c is designed to cool a maximum of 20 degrees from the outside temperature. Pretty simple math: if it’s 100 outside and your a/c is getting to 80 or below – it is doing its job.

Although there is nothing you can do to control the outside temperature, there are several things to prevent the hot air from coming inside:

  • Keep your blinds closed during the day
  • Wait until it’s cooler outside to do laundry or run the dishwasher
  • Grill outside instead of turning on the stove or oven
  • Set your thermostat higher so your a/c unit gets a break
  • Change you air filter
  • Cut back any shrubs or debris around your outdoor unit
  • Spray down condenser with hose
  • Don’t close off vents, your system needs to dispense air evenly without too much pressure

Like any mechanical system, your a/c needs to be maintained. The majority of service calls we receive in the Summer can be prevented with maintenance in the Spring. If you’ve been lucky enough to not have an emergency so far, you should seriously consider call us here at LHT Cooling, Heating & Refrigeration to have your system cleaned and checked. It still may not make it cooler in your home, but it will at least keep it from failing from overworking.

So now you know what your air conditioner can’t keep up with the 100-degree heat wave!

It is scorching hot outside, and you find your air conditioner running all day, and you wonder if it’s fine. On average, an air conditioner can cool your room in 15 to 20 minutes, after which the unit shuts itself down.

However, if it is scorching hot outside and the temperature is above 80 degrees, your AC unit may run for the whole day. In some cases, it may never turn off! HVAC experts say that it’s completely fine for your AC to run all day. Some AC units are designed to work at full capacity, and some people get this AC installed in Everett, WA.

However, it’s advisable to switch it off every few hours to ensure that – 

  • Your bill amount is less
  • No breakdown of the system occurs
  • Its cooling is not affected

It’s always better to schedule an annual check and get your AC repair in Everett, WA, when needed.

What should my AC be set at on a 100 degree day?

How cool should my house be if it's 100° outside? The majority of air conditioning units are designed to only cool the air about 20 degrees from the outside temperature. If the temperatures outside are approaching triple digits, you should set your thermostat at about 78°.

Is it normal for AC to run all day on a hot day?

Here's the thing: It's normal for your AC to run continuously during hot summer months. You see, on extremely hot days—we're talkin' high 90s to 100s—your system needs to keep up with the incoming heat. To do that, it will run longer in order to maintain a constant, desired temperature in your home.

How long should AC run on hot day?

As we said, an air conditioner should run for about fifteen minutes- if your ac runs all day long, especially on hot days, it's time for some maintenance! This is bad for your air conditioner and bad for your electricity bills. That's why we recommend an annual tune-up to keep your AC in tip-top shape.

Why is my air conditioner running all day?

If either the evaporator or condenser coils are dirty/blocked, your AC will run constantly because either heat isn't being absorbed from your indoor air or the condenser can't dump that heat outside. Things to check for: A visible layer of dust or dirt on the evaporator or condenser coils.
