How to Test & Improve Your Air Conditioner’s Efficiency

1. Step 1: Turn the AC unit on.
2. Step 2: Place a thermometer on the supply register.
3. Step 3: Keep the thermometer in place for at least five minutes.
4. Step 4: Repeat thermometer reading at the return vent.
5. How do I know if my air conditioner efficiency is good?

What are normal AC readings?

What are my A/C pressure readings telling me about my A/C system?

• An A/C System that is working properly should have 150 PSI on the high side and 30 PSI on the low side.
• 250 PSI / 30 PSI = You have air somewhere in the system.
• 250 PSI / 50 PSI = The system is overcharged and the condenser is not cooling.

What are good AC pressures?

These pressures will vary depending on ambient temperature (temperature of the outside atmosphere), but ideally, you will want to see your low side pressure between 30-40 psi and your high side pressure between 150-175 psi.

What is a good AC cycle?

Ideally, a properly operating air conditioner should cycle for roughly 15 to 20 minutes, two to three times per hour. If the temperature inside your home is very high, is much higher than the temperature that your thermostat is set at, or the outside temperature is very high, the run time will increase.

How do I know if my AC is cooling properly?

Your blower is still working if you can hear its fan whirring and you can see the blades moving. It’s cooler inside. Nothing’s worse than walking into your home after a day in the sun to a hotter atmosphere. If the indoor temperature is cooler than the outdoor temperature, the air conditioning unit is fine.

How do I know if my AC is energy efficient?

A room air conditioner’s efficiency is measured by the energy efficiency ratio (EER). The EER is the ratio of the cooling capacity (in British thermal units (Btu) per hour) to the power input (in watts). The higher the EER rating, the more efficient the air conditioner.

How much temperature is best for AC?

According to the Department of Energy1, 78° Fahrenheit is the sweet spot for air conditioners to balance energy savings and comfort when people are at home and need cooling.

Should my AC run all day?

How Long Should You Run Your AC Each Day? During a warm or humid day, an average air conditioning unit should run for about 15 or 20 minutes. But when it’s consistently over 80 or 90 degrees all day, your AC unit might run more often to keep up. In some cases, it may never turn off – and that’s fine!

How many hours should AC run in summer?

In a perfect situation, an air conditioner should run for 15-20 minutes at a time in mild temperatures. Any less than that and your AC could be too large for your home – more on that below.
