A Complete Guide to Reducing Cooling Costs in Your Home

You want to stay comfortable throughout the long, hot summer months, but you don’t want to break the bank keeping your home cool. Fortunately, there are plenty of energy-saving ways to maintain your comfort and to reduce cooling costs at the same time. 

Here, we’ll explore how much you can really save on your energy bills with some DIY energy-saving tips, a room-by-room guide to cutting back energy consumption, and ways you can take advantage of rebates and incentives to save even more.

Can I Really Save Money on Cooling Costs?

Over the last 20 years, the Energy Information Administration (EIA) found that more and more U.S. homes were using some form of air conditioning, peaking at just under 90%. Of those, 66% rely on central AC to keep their home comfortable during the summer. In total, the EIA estimates that around 12% of all home energy expenditures come from cooling systems. 

While exact numbers are difficult to pinpoint, the U.S. Department of Energy (DOE) estimates that most households can save around 3% on cooling bills for every degree the thermostat is moved up. So, if your thermostat is typically set at 68 degrees in the summer and you push it up to 72 degrees, you could ultimately save around 12%. On an average summer electricity bill of $178, that would be a savings of over $21, which can really add up over time. 

Combine those thermostat settings with other cost-saving measures, and the savings snowball even more.  Savvy homeowners can make simple adjustments to bring their utility bills down even lower. So, where do you begin?

The Big Question: AC On or Off When I’m Not Home?

The air conditioner can’t run when it’s powered down, so it stands to reason that shutting off your HVAC system would provide the most savings, right? Yes and no. Saving money by shutting your AC off every time you leave the house is, unfortunately, just a myth. That’s because your home heats up quickly without any AC running, which means the cooling system will need to run harder and longer to catch up when you do get home. Ultimately, the AC unit ends up running for about the same length of time, but running it all at once to cool down a very hot home puts a lot of unnecessary strain on the system. This could lead to extra wear and tear on your HVAC system, and a shorter lifespan.

Turning the AC off when you leave is a viable way to save energy if you’re going to be gone for an extended time (think days or weeks). However, be aware that if you live in a very humid climate, that humidity can cause damage if left unchecked. So while you’d be saving on your energy bill, you might come home to unwelcome surprises and other costly issues (like mold and mildew damage). 

Ideally, instead of turning the AC off completely, you would make smart adjustments to your thermostat when you aren’t home in order to reduce your energy consumption and save money.

Ideal Temperature Settings for Cost Savings

No matter how energy-efficient your AC unit is, what really makes an impact on your utility bill is the temperature at which you keep your home during the summer. The Department of Energy recommends setting your thermostat to 78 degrees when you’re home and awake, increasing to 82 during the overnight hours, and then setting it to 85 when you aren’t going to be home. This balances comfort with lower consumption and subsequent energy savings.

Optimizing Ceiling Fans

We understand that for many people, the “comfort temperature” of 78 degrees sounds absolutely miserable. We get that! However, before you resign yourself to sweating through another scorching hot day, hear us out. Using ceiling fans in conjunction with a 78 degree thermostat setting will help you cut costs while maintaining your comfort. That’s because ceiling fans don’t cost much to run, but they circulate cool air around the room, making you feel more comfortable. This can be especially helpful if you have a ceiling fan over your bed to help combat those nighttime temperatures.

Top Tips to Lower AC Costs and Use Less Energy

Once you figure out your optimal indoor temperature and ceiling fan use, you can move on to other simple tactics that can help reduce your summertime energy consumption. Here are the steps you can take starting right away:

  1. Vent moisture. Humidity in your home makes you feel warmer, so whenever cooking or showering, turn on the exhaust fan. If you don’t have one, crack the window.
  2. Prevent solar heat gain. Shut blinds and drapes in the heat of the day, or install window film to cut down on radiant heat entering your home. Some window coverings allow natural light to enter but prevent heat gain.
  3. Don’t use appliances that heat the home. Cook outdoors with your gas grill instead of the oven, or use the microwave to cook simple summer meals.
  4. Install a programmable thermostat. Setting a cooling schedule that raises the temperature a few degrees when the family is sleeping or away from home can save you quite a bit, as mentioned above. A programmable thermostat will help you keep to your schedule, so that you don’t have to remember to reset the thermostat before you go to bed or before you leave home.
  1. Seal ductwork. Your ducts are key to utilizing your conditioned air efficiently. Make sure all holes are repaired and all segments sealed tightly so you don’t waste energy.
  2. Insulate and air seal. Insulate your attic to keep the sun from overheating it in the summer, compromising your cooling efforts. Seal cracks and gaps around windows and doors with weatherstripping and sealant.
  3. Buy Energy Star appliances. Energy Star, the government’s efficiency rating system for appliances, can guide you to the most efficient air conditioner choices for your home.

Room-by-Room Cooling Strategy

All of those great tips are just the start. There are other actions you can take to get that AC bill even lower, by targeting every room in your house:

Kitchen

Cooking in the great outdoors isn’t always a feasible option, but there are ways you can keep your kitchen cooler and cut back on energy usage:

  • Use smaller appliances, like microwaves or air fryers, for cooking when outdoor temperatures are high.
  • Prep meals in advance and store in the fridge so you can reheat easily without turning on the oven or stove.
  • Give leftovers time to cool off. Putting hot food in the refrigerator makes it work even harder. Let uneaten food cool on the counter before storing in the fridge.
  • Use the air-dry setting on your dishwasher to conserve energy and avoid putting that heat into the kitchen.
  • Use the exhaust fan over your stove to remove hot air and lower humidity.

Living Room

The living room is typically a central location where families gather together. But game nights or movie parties can be pretty miserable if the room is too hot and stuffy. Here’s what you can do to breathe some fresh air into it:

  • Keep the blinds closed. Especially on south-facing windows, shut the blinds or pull the curtains to block sunshine from heating up the space.
  • Switch to LED bulbs. Incandescent bulbs cost more to operate, and the put off heat. Switch to cooler, energy-efficient LEDs.
  • Unplug electronic devices. TVs and computers can put off heat when they’re plugged in, even if they aren’t turned on. If you won’t be using them for a while, go ahead and unplug them.
  • Utilize fans. If you have a ceiling fan, turn it on. If not, use floor fans and box fans to help circulate the air and make the space feel cooler.

Bedrooms

Bedrooms are a sanctuary, but they shouldn’t feel like a sweat shack.Here’s what you can do to stop tossing and turning in the heat and rest easy:

  • Run the ceiling fan. Having a fan directly over your bed can help you stay comfortable through the night, even with the thermostat set a few degrees higher. If you don’t have a ceiling fan, try adding box fans or stand fans.
  • Use blackout curtains or blinds. Not only do they block the light and help you sleep better, they can also prevent the sun from warming up the room.
  • Close the doors. Keep your bedroom closed off during the day when the AC is running so the cool air stays inside.

Bathrooms

Bathrooms are naturally humid and damp locations. When combined with high temperatures, it’s a recipe for mold and mildew. Here’s how to keep your cool in the bathroom:

  • Promote ventilation. Use the exhaust fan when showering, or crack a window if you have one. Keep the door open when it’s not in use to allow maximum airflow.
  • Avoid using heated appliances. When possible, opt not to use heat-generating appliances like hair dryers, curling irons, or towel heaters. 
  • Take a cool shower. Instead of cranking up the hot water, scale it back a bit so the water is just comfortably warm. This will keep the temperature more moderate and will reduce the steam and humidity.
  • Install low-flow fixtures. These will also help with using less hot water and conserve energy.

Basement

Basements are naturally a little cooler than the rest of the house, which could offer you a pleasant escape. But there are ways to keep it even more comfortable, including these:

  • Use a dehumidifier. Basements are notoriously damp, which can be a problem in hot weather. Use a dehumidifier to remove moisture from the air and help it feel cooler.
  • Use a zoned system. Since basements aren’t always used, a separate AC unit or mini-split air conditioner could help keep it comfortable only when in use.
  • Close off some vents. Because basements are cooler than the rest of the house, it’s pointless to direct a lot of cold air down there. Instead, close off the vents to help push cool air to other parts of the home.
  • Check your insulation. An unfinished or partially finished basement may not be totally insulated. Add insulation where needed to keep a more consistent temperature. 

Save with Federal Tax Credits and Rebates

If it’s time to install a new air conditioner in your home, you can still save money, both at the time of purchase and in the long-term. Choosing an EnergyStar unit is a great first step, but there are also numerous incentives and rebates you can take advantage of: 

  • The Energy Efficient Home Improvement Credit: This federal credit can apply to heat pumps, central air conditioners, insulation, doors and windows, and even a home energy audit.However, the credit expires at the end of 2025, so all purchases must be made before the deadline.
  • High-Efficiency Electric Home Rebate Program: This is part of the Inflation Reduction Act, and offers upfront rebates for qualifying households on the purchase of a heat pump or heat pump water heater.
  • Residential Clean Energy Credit: This is another federal credit that can be used for homeowners who have invested in renewable energy in their home. This can include adding solar panels, wind energy, or geothermal heat pumps.
  • State and Local Tax Credits: Be sure to check for any available credits in your state or municipality. Some states will offer their own incentives for upgrading to energy-efficient HVAC equipment.
  • Manufacturer or Utility Company Rebates: HVAC manufacturers and utility companies both may offer rebates when purchasing high-efficiency products and services. Always check before you buy to see if there are available incentives.

When to Call in an HVAC Professional

Most of the tips we’ve listed here can be implemented right away with no special skills or knowledge needed. But there may come a time when you need help from a qualified HVAC technician. If you believe your air conditioner or HVAC system is nearing the end of its lifespan, it’s probably time to make that call. Additionally, you want to reach out to a trusted HVAC professional at least once a year for a regular tuneup to make sure you’re staying on top of your preventive maintenance. Finally, if you notice anything unusual with your air conditioner — like a noticeable unpleasant odor, strange noises, or smoke — it’s time to make the call. An HVAC pro can take a look at your system and make sure everything is in good working order, and can also give you some tips on how to maximize efficiency and energy savings.
