Summer Energy Saving Tips, Including Energy Efficient Windows
10:43

Summer can make even a comfortable home feel stuffy, uneven, and expensive to cool. The good news is that you do not need to overhaul your whole house to start saving energy. A few simple changes can help reduce heat buildup, improve comfort, and lower the strain on your cooling system. And if your windows are older, drafty, or letting in too much heat, energy-efficient replacement windows may be worth a closer look.

Quick Energy Saving Overview

 Start with the easy fixes first. Replace dirty air filters, use ceiling fans only in occupied rooms, keep blinds or curtains closed on sunny windows, and raise the thermostat when you are away. If your home still feels hot near the windows or your AC seems to run nonstop, it may be time to compare energy-efficient replacement windows. Joyce offers custom-made replacement windows, factory-direct manufacturing, and an online calculator that gives homeowners a ballpark project range before booking a consultation.

Check Your Air Filter Before Your AC Works Harder Than it Should

A dirty air filter can restrict airflow and make your cooling system less efficient. That can mean reduced comfort and more wear on the equipment over time. Before summer heat peaks, check your filter and replace it if it looks clogged or dusty. It is one of the simplest maintenance tasks a homeowner can do.

Use Ceiling Fans to Feel Cooler Without Overworking Your AC

Fans do not lower the room temperature, but they can help people feel cooler. The Department of Energy says using a ceiling fan with air conditioning can allow you to raise the thermostat setting by about 4°F with no reduction in comfort. Just remember to turn fans off when you leave the room, because they cool people, not empty spaces.


Block Direct Sunlight During The Hottest Part of The Day

Windows are one of the easiest ways for summer heat to enter your home. To help keep indoor temperatures more comfortable and reduce cooling demand The Department of Energy recommends: 

  1.  Installing or using window coverings to prevent daytime heat gain 

  2. Closing blinds, curtains, or room-darkening shades on the sunny side of the house 


Set Your Thermostat as High as Comfortable

You do not have to make the house miserable to save energy, but it helps to avoid overcooling. The Department of Energy recommends setting your programmable thermostat as high as comfortable in the summer and raising the set point when you are away from home. If you want more automation, ENERGY STAR says smart thermostats can help homes with high heating and cooling bills or long unoccupied hours save about $100 a year.

Let Ventilation Help When Conditions Are Right

Ventilation is one of the least expensive ways to cool a home when outdoor conditions allow it. The Department of Energy says it works best when combined with strategies that prevent heat buildup, such as shading and fans. For homeowners in milder evening conditions, this can be a helpful part of a broader summer comfort plan.

Know When Your Windows May be Part of The Problem

Sometimes high summer cooling costs are not just about the thermostat. If rooms feel hotter near the glass, your home has uneven temperatures, or your windows are drafty, hard to open, or showing signs of age, the windows themselves may be contributing to comfort and efficiency problems. Joyce’s current replacement window page says new windows can help improve comfort, energy efficiency, curb appeal, and everyday function.

Energy Efficient Windows for Summer and Winter

What Makes a Window More Energy Efficient?

When shopping for replacement windows, it helps to understand a few basic terms. Joyce’s own educational content highlights features like U-factor, solar heat gain coefficient, and Low-E coatings. NFRC also explains that solar heat gain coefficient measures how well a product resists unwanted solar radiation, and notes that a lower value helps keep your home cooler in summer.

In plain language, homeowners should think about energy-efficient windows this way: better-performing glass packages can help reduce unwanted heat gain, improve comfort near the window, and support a more efficient home overall. Joyce's replacement windows are designed to help reduce drafts, improve insulation, and make the home feel more comfortable throughout the year, depending on the collection and options selected.

Why Homeowners Look at Joyce for Replacement Windows

Joyce positions its replacement windows around custom fit, comfort, efficiency, and factory-direct manufacturing. The windows are custom made for each home, and explains that “factory direct” means Joyce manufactures its own windows rather than acting only as a reseller. That gives the brand a stronger angle for this blog than the original post used.

Joyce also offers a Window Pricing Calculator. The site says the estimate is a ballpark range based on typical inputs, and that final pricing is confirmed during a design consultation and on-site measurements. That makes a stronger, lower-friction CTA than a generic “contact us” close.

Air Conditioner Filter

Check your air conditioner's filter every time you receive your utility bill. Look for a dust build-up that can restrict the airflow and place stress on the system. This added stress places wear and tear on the unit, and increases operation costs. Filters can be washable or disposable. Most hardware stores carry inexpensive, fiberglass filters that are disposable. Measure the existing filter or filter opening. You want to buy the proper fitting filter. If fitting is not correct, it will not filter the debris. It is best to keep several filters on hand.

Check the Setting on your Thermostat

Set the thermostat at 78 degrees or higher for the most energy efficient operation. Each degree below this setting adds 6% to your cooling costs. Use a programmable thermostat to routinely raise the inside temperature while you are at work or routinely away from home for 4 hours or longer.

Pre-set your thermostat to adjust back to your normal comfort range 1/2 hour before arriving back home. This automatic adjustment reduces the cumulative operation of the air conditioner while you are away, and eliminates any discomfort when you arrive home.

Adjust the Water Heater

Adjust the water heater and save. Decreasing the water heater temperature from 140 degrees to 120 can help save up to $85 per year. A setting of 120 degrees is sufficient for most household needs. If you head out of town, turn it off entirely. There’s no need to heat unused water. Plus, once turned back on, most models will reheat the water to the set temperature in about an hour.

Use Fans and Ventilation Strategies to Cool Your Home

Use fans to move the air inside your home. If you use air conditioning, a ceiling fan will allow you to raise the thermostat setting about 4°F with no reduction in comfort. Use of ceiling fan gives the sensation that it is 5 degrees cooler than the actual temperature.

Turn off ceiling fans when you leave the room. Remember that fans cool people, not rooms, by creating a wind chill effect. Shade windows on the sunny side of your home, keeping the drapes closed or add room-darkening shades to block out the heat from the sun.

Purchase Energy Saving Replacement Windows

One great way to conserve is to replace your homes windows with energy saving windows.
Energy saving windows has certain features that are made to reduce energy waste in one way or another. These features include; multiple glazing, thickness of air space, Gas filled, Tinted glass, Low-e, and edge spacers. Any of these features will affect the energy performance rating, which is displayed on the window when you purchase it. Replacing your old windows with energy saving windows will insulate your home up to 4 times more than your old windows you have now, this will save you money and our environment in the long run. Choosing the right window can be confusing and your energy-saving window contractor can help you find the right choice of windows for you.

Energy savings isn’t just for the winter. These energy saving tips and changes will make this summer more comfortable and keep more green in your pocket.
