June 19, 2020

As the temperature goes up, so does your AC expenses. To keep your AC expenses under control you may be thinking, is it cheaper to leave your AC on all day in the summer in San Jose?

It’s a common belief that turning your AC on and off throughout the day is inefficient. This is actually a myth.

Keeping your air conditioner running all the time means you’re not using it very efficiently. We suggest adjusting your thermostat higher when you’re elsewhere, and turning it down when you come home. You can achieve this with a programmable thermostat. Or, a smart thermostat will do the work for you.

It’s far more work for your system to stay at a constant setting all day long. It can also lead to a lot of strain on your system, since it’s repeatedly turning on and off.

So, on top of it increasing your electricity bills, it may also result in a shortened life expectancy for your AC.

In any case, the greater the difference between your house’s temperature and the outside temperature, the more your air conditioning bills will be. So, what can you do to remain cool and keep your energy bills down in the hot weather? Here are our tips based on recommendations from the U.S Department of Energy (DOE) and ENERGY STAR®.

6 Approaches to Enhance Your Air Conditioner’s Energy Efficiency

  1. Change Your Thermostat. The DOE says that you can save up to 10% per year on heating and cooling by turning up your thermostat 7-10 degrees when you’re away. During the summer months, it’s suggested to set your thermostat at 78 degrees while you’re home and 88 degrees when you’re out. It’s additionally important to avoid setting your thermostat to a colder setting than usual when you turn on your AC. This doesn’t actually cool off your house any sooner, it just results in higher electric costs. While these temperatures might feel high, there are additional approaches to keep comfortable without having to consistently run the AC unit.
  2. Utilize Fans, Curtains and Blinds. ENERGY STAR says increasing the thermostat by only 2 degrees and utilizing your ceiling fan can decrease energy by up to 14% over the course of the cooling season. It’s important to keep in mind that fans cool people, not rooms. So, when you head out of the room, turn the fan off to save energy. Additionally, keeping blinds low and curtains shut throughout the day helps keep conditioned air in. There are also some window coverings designed to deliver added insulation and enhance energy efficiency.
  3. Properly Seal All Doors, Windows and Openings. Leaky openings around a residence let conditioned air to easily get out and warm air to get within. This could lead to your air conditioner needing to work harder to keep your house cool and your AC expenses to increase. Make certain that any gaps, doors and windows are properly sealed. Caulking or weather-stripping are quick mends for leaks or drafts near windows and doors.
  4. Plan for Regular Maintenance. Scheduling air conditioner maintenance assures that your equipment is always performing at its best. This permits our pro to identify simple issues before they turn into major problems. A well-kept AC unit is usually more efficient and can even last for a longer period of time.
  5. Install a Smart Thermostat. One of the best ways to ensure comfort and energy savings is with a smart thermostat. This thermostat instinctively changes the temperature based on your daily schedule. It works along with your smartphone to notice when you’re at home or elsewhere to maximize your energy efficiency. In fact, ENERGY STAR mentions that a smart thermostat could actually save you about $180 yearly on HVAC costs.
  6. Consider Replacing Your AC. You can anticipate an adequately cared for AC to last for 15-20 years. But if you’re often needing us for air conditioning repair or your energy expenses are increasing with no change in thermostat settings, it might be time for a new system. We supply a number of energy-efficient air conditioners, like ENERGY STAR models that can help you save more on cooling without negotiating comfort.
