How To Save On Home Air Conditioning & Energy Costs In The Summer

Summertime has quite a bit going for it: pool events, yard cookouts, baseball video games. The solely factor that’s not so nice about summer season is the warmth. On a blazing July day with the temperature in the 90s (and on the East Coast, soaking humidity on prime of that), it may be tempting to keep indoors all day with the air conditioner cranked up.

Unfortunately, air-conditioned consolation comes with a excessive price ticket. In 2019, carbon emissions-reducing technology company Sense analyzed family electrical payments from throughout the nation to calculate summer season cooling prices. It discovered the common price ranges from round $25 in Washington state to over $450 in blazing-hot Arizona.

But there are methods to cut back that price. An energy use chart from Lowe’s says a big central A/C system makes use of about 3,800 watts, or 3.8 kilowatt-hours for every hour it’s used. By distinction, a small window air conditioner makes use of 1,200 watts, and a field fan makes use of solely 200. Thus, operating your central A/C much less can shrink your utility invoice — and your carbon footprint as effectively.

So when the summer season solar comes beating down on your property, it will definitely makes its means into the inside. This impact is called “solar heat gain.” You can stop photo voltaic warmth achieve all through the home with a mixture of insulation and blocking applied sciences in addition to avoiding the addition of additional warmth.

1. Keep Windows Shut

Keep your home windows closed throughout the day when it’s hotter outdoors than it’s inside. Even if they supply solely slightly insulation, slightly is healthier than none. In the night, when it has cooled down outdoors, open the home windows to let in cooler air.

The older your home windows are, the extra warmth can leak by way of them. Many previous home windows have only one pane of glass, and their frames aren’t effectively insulated.

But newer home windows have two or three panes with an insulating layer of fuel sandwiched between them. Modern energy-efficient home windows even have better-insulated frames, so that you lose much less warmth round the edges of the glass. According to Energy Star, upgrading to Energy Star-rated home windows can lower 7% to 24% out of your vitality payments.

However, changing home windows is a pricey job. According to Angi (previously Angie’s List), a typical price is $200 to $1,300 per window. If your present home windows are fairly new and in fine condition, changing them in all probability isn’t value the price.

For instance, in accordance to Energy Star, the common U.S. home-owner spends about $875 per year on heating and cooling. If that’s the case for you, new home windows can solely prevent $210 per year at most. If you substitute 10 home windows at $600 every, it should take over 28 years for them to pay for themselves. That may very well be longer than you anticipate to personal the house.

3. Add Storm Windows

A less expensive means to get the advantages of a multipaned window is to set up short-term storm home windows. These are inflexible panes of glass or plastic you’ll be able to put both outdoors or inside your current home windows, trapping a layer of heat-blocking air in between.

The DOE estimates that new storm home windows price between $60 and $200 per window and may prevent anyplace from 12% to 33% on your annual heating and cooling payments. Installing them is an easy DIY job that takes 20 to half-hour per window.

The DOE studies that in a heat, sunny local weather, including a radiant barrier to your attic can cut back your total cooling prices by 5% to 10%.

6. Seal Doors and Windows

Even the best-insulated partitions can’t preserve your own home cool if huge gaps round your doorways and home windows enable cool air to escape. Fortunately, it’s straightforward to seal these air leaks with caulk or weather-stripping.

The DOE says caulking is an easy DIY job that takes simply a few hours, prices lower than $30, and may lower your vitality use by 10% to 20%. Weather-stripping around windows is even cheaper and simpler, requiring only one hour and $5 to $10.

7. Absorb Less Heat With Light-Colored Paint

Dark surfaces heat up a lot more in the sun than gentle ones. In a 2018 experiment by CNET, a brown stucco wall bought 25 levels F hotter on a sunny day than the similar wall painted white. So portray your own home a lighter coloration may help cut back the quantity of warmth it absorbs from the solar, lowering your air-conditioning prices.

The draw back is {that a} lighter-colored home additionally absorbs much less warming daylight in the wintertime. Thus, this trick will solely prevent money in case your summer season cooling prices are larger than your winter heating prices. The Home Energy Saver tool can let you know if that applies to you.

Having your own home professionally repainted prices between $1,7750 and $4,211, in accordance to Home Advisor. However, you are able to do it your self with $700 to $1,300 value of paint and provides.

8. Install a Cool Roof

The subsequent time you want to substitute your roof, contemplate a “cool roof” — one made with particular reflective supplies or coatings to block out the solar’s rays. According to the DOE, cool roofs may keep over 50 levels F cooler in the summer season solar than commonplace dark-colored roofs, and so they price about the similar.

However, cool roofs additionally take up much less warmth in the wintertime. Thus, like light-colored paint, they’re most helpful in heat climates the place folks spend extra on summer season cooling than they do on winter heating.

9. Plant Shade Trees and Shrubs

Trees cool the space round them in two methods. They present shade, and so they transfer and launch water vapor by way of their leaves. According to the DOE, the air temperature instantly beneath a tree could be as a lot as 25 levels cooler than the air instantly above a close-by street.

Deciduous bushes — the form that lose their leaves in the fall — can present summer season shade whereas nonetheless letting the solar shine by way of their naked branches in wintertime. Tall bushes on the south facet of your property supply the greatest shade for the roof, whereas bushes with limbs nearer to the floor are useful on the west facet for blocking out the decrease afternoon solar.

The DOE says a 6- to 8-foot-tall deciduous tree can present shade in your home windows as quickly as you plant it. Within 5 to 10 years, it may possibly start shading the roof.

Aside from lowering your cooling wants, most of those heat-reducing steps additionally save vitality instantly, lowering your electrical invoice nonetheless extra. And as a bonus, they’re good for the atmosphere as effectively.

Cool Yourself Without Air Conditioning

Many on-line articles and movies declare you may make your personal air conditioner with lower than $30 value of components. A typical setup entails boring some holes in a bucket or ice chest, filling it with ice, pointing a desk fan into the bucket, and directing the airflow by way of items of PVC pipe.

There are two issues with this concept. First, it’s not likely an air conditioner. It’s extra related to a swamp cooler, which implies it’s ineffective in humid climates.

And second, these DIY swamp coolers don’t really work very effectively. In a take a look at performed by Consumer Reports, an ice-chest “air conditioner” was solely ready to cool a room by 2 to 3 levels F — and just for about half-hour. A bucket-based design examined by the Philadelphia Inquirer lowered the temperature by not more than 1.5 levels F.

The backside line is that these do-it-yourself air conditioners do little if something to cool a room. In most circumstances, you’ll get higher outcomes utilizing the desk fan in the conventional means and saving the ice for a chilly drink.

But that doesn’t imply turning on the air conditioner is your solely different to sweltering. There are many official methods to keep cool that use quite a bit much less vitality and money.

13. Use Fans

A fan doesn’t cool your room. Instead, it cools you instantly by blowing away the cushion of heat air that accumulates round your physique.

That doesn’t assist a lot in excessive warmth (over 95 levels F) as a result of there’s no cooler air to substitute it. But at decrease indoor temperatures, a fan could make you are feeling a number of levels cooler. According to the DOE, operating a ceiling fan permits you to really feel equally comfy with the thermostat 4 levels F larger.

You should buy a basic desk fan for as little as $15 and a extra highly effective tower fan for round $60. Even on its highest setting, a tower fan makes use of lower than 100 watts of vitality — far fewer than the 1,200 watts a typical one-room air conditioner makes use of.

To get the most profit out of your followers, dress evenly. If you’re sitting round in denims and a sweatshirt, these heavier garments are trapping scorching air subsequent to your physique. Switching to lighter garments, similar to shorts and tank tops, makes it simpler in your sweat to evaporate and preserve you cool.

A typical window fan makes use of not more than 100 watts of electrical energy.

If you need much more airflow, you’ll be able to set up a whole-house fan. It mounts in your ceiling and pulls in air by way of the open home windows. According to Family Handyman, the followers can decrease your property’s temperature by 5 levels F or extra in minutes utilizing one-tenth the vitality of an air conditioner. Expect to spend just a few hundred {dollars} on the fan and one other few hundred to have it put in.

16. Use a Swamp Cooler

A swamp cooler, additionally known as an evaporative cooler, blows heat air over water-soaked pads. As the water evaporates, it cools the air by as a lot as 40 levels F. According to the DOE, swamp coolers price about half as a lot to set up as an A/C unit and use solely 25% as a lot vitality.

Free-standing swamp coolers begin at round $130. You can have a whole-house evaporative cooling system put in for about $2,500, in accordance to HomeAdvisor.

The major downside of this kind of cooling system is that it solely works in dry climates. This map from the equipment company Sylvane exhibits which components of the nation are greatest suited to evaporative coolers.

Run Your Air Conditioner Efficiently as Needed

In some components of the nation, a great fan and a few ice packs are all you want to survive the summer season warmth. But in actually scorching, humid areas, there’s no means to make it by way of an entire summer season with out switching on the A/C. On these days when air con is a should, the greatest means to save vitality and money is to preserve your A/C system operating as effectively as attainable.

Air conditioners are based mostly on the physical principle that when a liquid will get transformed to a fuel, it absorbs warmth. They work by circulating a fluid by way of a sequence of coils, evaporating and condensing repeatedly. As the fluid evaporates, it absorbs warmth, eradicating it from the air inside.

17. Maintain Your Air Conditioner

Routine upkeep could make a world of distinction when it comes to your air conditioner operating effectively — and effectivity saves you money on your cooling invoice every month. Easy duties you are able to do your self embrace:

18. Reduce A/C Energy Use

Aside from common upkeep, you’ll be able to take a number of different steps to cut back your air conditioner’s vitality consumption. For instance:

One energy-saving tip it is best to ignore is closing the registers in rooms you don’t use, similar to a spare bed room or formal eating room. A 2003 examine at the Lawrence Berkeley National Laboratory discovered that in a typical home, doing so really will increase the air conditioner’s vitality use as a result of it leads to extra leakage in the duct system.

Upgrade Your Air-Conditioning System

According to the DOE, right this moment’s extra environment friendly central A/C techniques use 30% to 50% much less vitality than these constructed in the mid-Nineteen Seventies. Even in contrast to a 10-year-old unit, a brand new air conditioner can lower cooling prices by 20% to 40%. So should you at the moment spend $133 per year on summer season cooling like the common American family (per Sense), upgrading your system may prevent up to $53 per year.

But in case your central A/C system nonetheless works, you in all probability gained’t save any money by changing it. According to HomeAdvisor, shopping for and putting in a brand new central air-conditioning system prices round $3,800 to $7,500 on common. That means your new system will take over 70 years to pay for itself.

Another question to contemplate earlier than changing your central air conditioner is whether or not to swap to a special kind of system that makes use of much less vitality. Whether you select to substitute your previous A/C with a brand new central air system or one in every of the options relies upon on your heating and cooling wants and the way a lot you stand to save with every system.

19. Increase Efficiency With a New Central Air-Conditioning System

If you’ve got current ductwork and your previous A/C system wants changing, it’s value selecting an energy-efficient one. The effectivity score of a central air conditioner is known as its “seasonal energy efficiency ratio,” or SEER. It’s a measure of how a lot vitality it makes use of to produce a particular cooling output. Old air-conditioning techniques usually have a SEER of 6 or much less, whereas trendy ones can attain 20 or extra.

The measurement of your system can be vital. If your central A/C system is just too small for your own home, it may possibly’t cool the whole space on the hottest days.

On the different hand, a system that’s too giant for the home prices extra and is much less environment friendly. That occurs as a result of it solely wants to run for a couple of minutes at a time to carry the temperature down close to the thermostat — however that isn’t lengthy sufficient to take away humidity. An outsized system may also depart some areas too heat as a result of it doesn’t run lengthy sufficient.

20. Opt for Window Units

There’s no level in cooling an entire home should you’re utilizing only some rooms. If you have a tendency to spend most of your day in a single room, similar to your property office, maybe you’ll be able to skip the central air con and simply use a window air conditioner in that one room. A brand new window air conditioner sometimes prices between $110 and $400 and makes use of round 1,200 watts to run.

Even in case you have to set up window models in a number of rooms, it’s cheaper to cool one room at a time than a whole home directly, and there’s no vitality lost to leakage by way of the duct system. But should you want to cool a number of rooms concurrently, a central A/C system is extra environment friendly.

21. Put in a Mini Split System

Instead of utilizing a single evaporator and a fan to cool the entire home, these techniques have a number of indoor air-handling models hooked to a single condenser and compressor. This setup permits you to cool particular rooms as an alternative of cooling the entire home. It additionally eliminates the want for ductwork, so there’s no air leakage.

Mini break up techniques are simpler to set up than central A/C techniques, particularly in homes that don’t have already got forced-air heating. Their major downside is that they’re normally dearer. According to HomeAdvisor, a ductless system prices about 30% extra to set up than a brand new ducted system.

But that applies solely to properties that have already got ductwork from an current heating or A/C system. In a home with no ductwork, a brand new break up system prices up to 50% lower than a brand new central air-conditioning system.

22. Invest in a Geothermal System

A regular air conditioner transfers warmth from your own home to the air outdoors, which is already fairly scorching in the summer season. By distinction, geothermal techniques switch indoor warmth to the floor about 10 toes beneath the floor, which stays at round 54 levels F all year lengthy.

According to the DOE, a geothermal system makes use of 30% to 60% much less vitality than a conventional air-source system. Also, you need to use it for heating your property in the winter in addition to for cooling it in the summer season.

Geothermal techniques are costly — between $10,000 and $30,000, in accordance to Family Handyman. That’s much more than a traditional HVAC system. But you might qualify for an Energy Star tax credit to cover a part of the price, and it may possibly prevent between 20% and 60% on house heating and cooling payments.

Final Word

One factor you shouldn’t do to save on your summer season cooling prices is let the temperature in your own home climb to harmful ranges. When the temperature is above 90 levels F and the humidity can be excessive, your physique can now not cool itself by sweating, placing you in danger for heat-related sicknesses, similar to warmth exhaustion or warmth stroke.

Symptoms of warmth sickness embrace excessive thirst, muscle cramps, fatigue, headache, dizziness, and nausea. If you begin to have any of those signs on a scorching day, neglect about your electrical invoice and funky your self as shortly as attainable, or you might find yourself in the emergency room.
