How Your AC Can Ruin a Good Night’s Sleep

May 25, 2017

Air conditioners are our best friends during hot summer days, but did you know they could be making you lose sleep at night? 

In fact, your AC can ruin your sleep if the:

  1. Temperature is too high or low

  2. Velocity is too high

  3. AC is too loud

 In this article, we’ll go into each of these problems and discuss how you can fix them.

Let’s start with velocity...

Problem #1: Temperature is too high or too low

If it’s too hot or too cold in your bedroom, you may be losing sleep.
Generally, your bedroom temperature should be between 60–67° Fahrenheit. Temperatures above 75° F and below 54° can disrupt your sleep.

How to get the right temperature

Make sure to set your thermostat to a temperature between 60–67° F before you go to bed. If you have a smart thermostat, you can program it to automatically adjust to that temperature around bedtime.

Problem #2: Your AC’s velocity is too high

A recent study found that ACs with a higher airflow velocity can disrupt sleep patterns.

OK... but what’s airflow velocity, you ask?

Airflow refers to the air your AC projects into your home. Velocity measures how fast that air is moving. 

So, the research suggests that the faster the air is moving, the more uncomfortable it is for sleeping, especially if you’re a light sleeper.

How to reduce your AC’s airflow velocity

A professional can keep your room cool while reducing airflow velocity by providing these 2 solutions: 

  • Install diffusers: Supply-air diffusers spread, or diffuse, the air around the room. With a correctly-sized diffuser, you can control how air is distributed into your bedroom so you don’t feel your system’s airflow velocity.
  • Adjust blower airflow settings: An HVAC professional can adjust the settings on your AC’s blower motor to reduce airflow velocity.

What you should do: Contact an air conditioning professional to adjust the settings on your AC’s blower motor or add a diffuser to reduce airflow velocity. Only a licensed air conditioning expert has the proper tools to measure velocity and make any necessary airflow adjustments to your system.

Problem #3: Your AC is too loud

When you’re trying to sleep, nothing is more annoying than a loud air conditioner.

Your AC could be too loud because it has some mechanical problems or it’s not running efficiently. Learn more about what problems make your air conditioner loud

But if nothing is wrong with your AC, it could just be that your AC has a high decibel (dB) rating. The higher the decibel rating, the louder the AC. If your air conditioner is 70+ dB or higher, it’s going to be distractingly loud.

You can find your air conditioner’s decibel level in your AC’s manual (or marketing/specs pamphlet), which you can usually find on the manufacturer's website or by contacting the manufacturer directly.

How to quiet your noisy AC

Contact an air conditioning expert to inspect your system to make sure it’s running efficiently and no problems. If your AC has a loud dB rating, your technician can recommend quieter models.
