Tips to lower your energy bill in the Arizona heat

Is your summer electricity bill making you moan? Are you looking for effective ways to lower your bill?

Any Arizonan can tell you their electric bills are skyrocketing as the temperature in the state does the same thing every summer. Most consumers struggle to avoid high energy costs during the state’s hottest season, even though the average price for a kW/hr in Arizona is lower than the national average.

With these tips from Day & Night Air Conditioning, Heating and Plumbing, you can see why lower summer electricity bills may be closer than you think.

Keeping your home livable and your energy bill low is a difficult balancing act. Use these tips to stay cool without breaking the bank.

Change your air filter

Replacing the air filter in your heating, ventilation and air conditioning system in a timely manner is just as crucial as changing the oil in your car.

All the dirt, dust, dander, and pet hair circulating through your home will pass through the HVAC filter. A dirty filter will prevent enough air from flowing through your system, resulting in low or no air filtration and increased stress on your system’s mechanical parts. This can lead to premature mechanical failure, which is the last thing you want in the middle of summer.

Change your filter every 15 to 60 days, depending on pollution levels, allergy problems and the number of pets you have, according to our local air conditioning expert, day and night air conditioning, heating and plumbing.

Use a smart thermostat

Smart thermostats help you determine what temperature to keep in the house all day and help you create a schedule. For example, you can set the temperature higher when you are not at home and lower when you are sleeping.

With the convenience of a mobile app, you can also set your air conditioner to start cooling before you go home from work, helping you reach a more comfortable temperature.

To save even more — up to 10% a year — set your thermostat back 7 to 10 degrees from its normal setting eight hours a day, according to the US Department of Energy. Indoor temperatures between 68 and 78 degrees are usually the most comfortable and efficient if you want to save on electricity without baking in the house.

Turn on your air conditioner when you are away

Contrary to popular belief, you should not turn off your air conditioner when you are on vacation.

“Turning it off will create problems in the house,” owner Jeff Martin of Day & Night Air Conditioning, Heating and Plumbing says in a video. “You can damage hardwood floors, paintings on the wall, melt candles, that sort of thing.”

Jeff recommends setting your air conditioner no more than 90 degrees when you are away to avoid problems.

“If your house is very hot, your refrigerator will struggle to keep your food cold,” he says. “You can actually do more damage to things in your house by leaving it out at all.”

Home Improvement Tips

If you have an old or drafty house, a lack of insulation drives up energy consumption. Fortunately, there are a few ways you can prevent the heat from coming in from the outside, according to Day Night Air conditioning, heating and plumbing:

  • Plant trees near windows to provide shade.
  • Add light-colored curtains and blinds to interior windows.
  • Install a shade screen on the outside of the window.
  • Replace single glazing with double or triple glazing.
  • Add insulation to ceilings and walls.
