Adding Insulation to Your Home Can Help You Stay Cooler This Summer

Schedule Now

Adding insulation isn’t something that should be left for your winterization to-do list. In addition to keeping you warm in winter, the right level of attic insulation keeps the Southwest Ohio summer heat from seeping into your air-conditioned living space. More insulation could cut your air conditioning bills by up to 15 percent.

Check Your Attic Insulation

If you’ve already got three or four inches of insulation, you’ll want to insulate to between R38 to R49 level. How deep your insulation should be to achieve these R levels depends on the insulation type. For R38 level, appropriate depths are:

  • Fiberglass batts: 12 inches
  • Loose-fill fiberglass: 14 to 17 inches
  • Loose-fill cellulose: 10 to 12 inches

Check the depth in different parts of your attic. You may find there’s plenty of insulation around the access door, but not enough toward the edges or in the middle of the attic. Also check for deteriorated insulation. This no longer forms an effective heat barrier and should be replaced.

Your Options for Better Insulation

If your current levels suggest the need to add insulation, you have two main options.

  • Batt insulation – These long sheets of insulation are available in fiberglass, cellulose and some more eco-friendly materials such as cotton from recycled jeans. If not carefully installed, batts may fail to fill in small crevices, leaving room for heat to escape.
  • Loose-fill (blown-in) insulation – This comes as small chunks of material, usually fiberglass or cellulose. These small pieces more effectively fill in corners and crevices. Loose-fill insulation requires a blowing machine for installation, but can be added over batts.

Installation Quality Matters

The effectiveness of your home’s insulation depends on proper installation. A professional can help you decide which insulation best meets your needs and determine the ideal amount. A pro can also do the tricky job of adding insulation to fill in crevices sufficiently without blocking the critical sources of ventilation that protect your attic from mold and heat damage.

"Ernie & Mike did a superb job on my new furnace and A/C installation. Despite having more than a day’s work to do, they came in and stayed until the job was done. They were organized, efficient, and protected the rest of the house well. Got both furnace and A/C installed the same day. Ernie was courteous, informative, and clearly knew his job better than anyone I’ve encountered before. The units look so good guests now get The Tour of our new system. Apollo is clearly not a fly-by-night company. I would recommend them to anyone in need of a new furnace and/or A/C."

"I called Apollo because of a water leak I thought I had in our upstairs shower going into the kitchen. Robbie came and assured me everything was fine & looked at all the other plumbing. He ended up changing a few pipes for our washer & clearing a drain. He was very nice & knowledgeable with all my questions. I ended up signing up for the care plan & was very happy with my service."

"The team at Apollo exceeded my expectations. As a business owner, my attention to the details and commitment to providing excellent service is high. From the sales rep. to the installation team, everyone’s performance was outstanding. For example, the installation team went to great lengths to protect our floors, placing floor runners and across the wood floors and up the stairs. They even were spot washing walls upon their departure. I highly recommend this company."

"We scheduled an estimate AND a tune-up. We knew something was wrong with our furnace, but hoped we could make it through the rest of the season. Upon telling Bill what our furnace was doing, he warned us immediately what the possible outcome was going to be; a cracked heat exchanger. He watched the flames roll backward, tested carbon monoxide levels, which were so high they meter’s last reading was 5,600 before saying “high”. He immediately shut it down, tagged it, and explained that with levels that high and children in our home he wanted off right away. He continued his inspection and showed us via a camera that not only was it cracked in multiple places, but had holes all over it. He gave us a few options for repairing it; his knowledge as well as genuine concern was beneficial and refreshing. Luckily we also scheduled an estimator, Micah, to come too and we were able to get costs between repairing and replacing (with several options). We decided to replace with a much higher efficiency furnace and one sized properly to our home. Hands down, not only did they both provide us great service and knowledge, but without sounding dramatic, they may have saved our lives. This was our first time calling Apollo, but it won’t be our last."

"Apollo is an excellent company. I always receive great service. Alex A. was professional and friendly. He kept me informed during the process of checking my furnace and heat pump to make sure they were working properly. The company makes sure you are notified who is coming and when they are on the way. All my interactions with the company have been wonderful."
