Why is My House So Hot?
Do you find yourself asking, “Why is my house so hot?” every year as summer hits? Your house may be letting in heat in ways you don’t even realize. If you want energy efficient alternatives to air conditioning, you need to stop heat before it reaches the inside of your home.

Figure out exactly why your home is hot and use some simple solutions to cool it down. This will help you find some comfort and save money. Let’s dig into the details of these issues and how to solve them.
Tips on Keeping Your House Cool in the Summer
Keeping your house cool in the summer is easiest if you stop heat from coming inside in the first place. If you block heat with insulation and air sealing, you don’t have to worry about heat trapping – your home will stay cooler than outside.
Use these techniques to block heat from windows, walls, and roof and you’ll find yourself using your a/c less and less.
Thermal Insulation Protects from Heat
Many older homes have poor insulation, allowing heat to get into your air-conditioned home.
Thermal insulation is most often used to keep a home warm during the winter, but it works for the summer months too. Insulating your home protects the inside of your house against outside temperatures, no matter what they are, making it easier to control inside temperatures.
Add insulation to slow the transfer of heat so your home stays cooler longer. Think about a nice cool beer on a hot day. If you put a koozie on it, it will stay cooler for much longer.
Fix Air Leakage to Cool Your Home
Check for leaks. If your windows have bad air sealing, they are letting hot air in and a/c out.
Small holes and cracks let hot air into your home just like they let cold air in during the winter. These holes can be in windows, around pipes, light fixtures, anywhere there’s a connection of materials or something entering or exiting your house.
Fix small leaks with caulk and use a foam sealant to fix larger gaps. Make sure to cover fans and always use proper ventilation and face masks.
Ways to Block Heat from Windows
How much light is coming through your windows? Are they south-facing?
Windows let in a huge amount of heat because they are your home’s main source of natural light. Anywhere the sun’s light goes, so goes heat. You can add many kinds of window treatments to block heat from windows, but most of them will also block light. Heavy curtains and blackout window shades reduce heat and reduce light. These do not trap heat because the heat source it coming from outside of the house.
These can be added to the whole house or just one room if you’re finding one room much hotter than the rest of the home.
Add a White Roof to Your Home
What color is your roof? Dark colors absorb heat where light colors reflect it.
Adding a white roof to your home helps reflect heat right where it’s beating down on it. You can add white paint, solar reflective asphalt shingles or clay, or concrete or fiber cement tiles. Any of these will give you energy efficient alternatives to air conditioning and extend the life of your roof.

Remove the Humidity
Humidity changes our perception of heat. If your home has extra moisture, it will add to the hot feeling and stick to you.
So, why is your house so humid? Your a/c unit could be too big. If your is cooled too quickly, the a/c can’t do its other job: dehumidifying your home. It needs time to do this second job, but if your unit is too big, it will turn off before it’s done.
You can get a new a/c unit that fits your home, or you can get a separate dehumidifier. You can also address this issue with other small changes. Reduce moisture inside by: ventilating while cooking, taking cooler, shorter showers, drying your clothes outside, and moving your houseplants outside for the summer.
Never Say, “Why is my room so hot?” Again
Once you’ve done all (or even a few) of these items, you won’t be asking yourself “Why is my room so hot?” anymore. You’ll be using energy efficient alternatives to air conditioning, and saving a lot of money on your energy bill.

Indow inserts were easy to measure, order and install. They've provided great insulation for old single-pane and stained glass windows in an antique home. We can significantly feel how much better the home holds heat.
I ordered two Indow inserts for my home. They are doing a great job, entirely happy with them and the ordering process.
I can't say enough good things about this product and company. Our house is 101 years old and the sidelites next to our front door are single pane ancient wavy glass which means when it gets very cold (Chicago temps) we can have an inch of frost covering the INSIDE of our windows. I was desperately searching for a solution so our front vestibule was not so cold and a friend recommended Indow. The process could not have been simpler and the temperature difference it has made is off the charts.
I have several historic single pane gridwork mullion windows. They're beautiful but have almost no thermal protection. Indows proved to be the perfect solution to preserve these windows while getting the thermal comfort we need. They were easy to install and work perfectly!
Amazingly easy to install even the safety chain holders. I. Noticed an immediate sound level difference and the room atmosphere became more solid feeling and pleasant. They also gave an insulating feature to the window drafts are non existent! The house is 50ft off a State highway that is heavily traveled in warmer months I'm confident the indows will handle it. I'm very pleased!
We ordered the acoustic inserts to help with road noise, and we've been sleeping so much better with them!
We used the windows inserts in our skylight. They are great! They the horrible drafts and noise out and were cost efficient. My only comment would be to provide better measurement and installation instructions for skylights specifically. It took us a lot of guessing and research to measure and install because skylight directions were not provided and the windows install guide doesn't always apply to skylights. Other than that though great product and I would buy again!
Our home was built in the late 1800s and we have spent a lot of money over the last 20+years restoring it.We did not want to replace the windows with modern windows because of the cost and originality. But the single pane windows come with a price also. the main reason we purchased the Indow window inserts is because of the condensation on the inside of the windows.We would literally have a take a towel and wipe them down every morning in the winter. There would be a puddle on the sill,and wood and water dont get along to well. SO we looked into the best solution to our problem and found Indow. Was reluctant to spend that much money but am super glad we did!! They have been installed now for over two months and our condensation problem has been virtually eliminated.!!! AND our furnace does not run as much as it did before. Over all it was money well spent!! The process was a little scary at first but they have a simple formula. And our contact person,Reed was awesome. Answered any questions i had and was always available.
Used to block interior side of a garden window in the the kitchen. Without insert, cold air literally poured into the kitchen making a winter jacket almost mandatory when preparing meals or washing dishes
Highly recommend! The team (Brian) took time to help me figure out the best solution. They were made and delivered faster than expected. It was very rewarding to install them because I could feel the cold air get squeezed out as they went flush against the single pane of glass. Solid quality and great fit.
My inserts fit beautifully into my 125 year old windows - many of which were 5 feet tall. Easy to unwrap and install. Great product and even better service! I liked the process of measuring the windows with a laser measuring tool which was easy to use and precise. The product came in good condition after shipping across country and was well marked. The customer support was excellent.
Received our Indow Windows and can tell they are blocking a lot of the noise we could hear. Right now the weather is mild, but hoping to notice a big difference when the summer heats up. Our house is in a historic district and we cannot change our windows. They are very drafty and thin glass. We only ordered two, but we are in the process of ordering for four more. Love that we don’t need to drill holes or anything and they just pop right in.
Every thing arrived in perfect condition, thanks to the very secure packaging. Windows fit as expected, although quite tight. After installation we noticed that the cold drafts were gone and the room felt a lot warmer. We are very satisfied with the product and the result.
Great customer service! Super satisfied with our windows.
Indow service and product is good. Reduced outside noise considerably.
