" USA Insulation of Austin did a fantastic job insulating my attic with blown-in fiberglass insulation (R-38). Before their visit, my attic had no insulation at all, and now it has a full 15-inch depth as promised. Ellie, the manager, was especially helpful and impressively prompt with communication, making the scheduling and setup very easy. Cody, the crew leader, and his team were careful, efficient, and genuinely friendly throughout the installation process. I particularly appreciated their patience and understanding when I was late letting them into the house due to losing track of time on a run, and when I forgot to leave clear instructions about locking up afterward. Despite these hiccups on my part, they handled everything professionally and courteously. Overall, I highly recommend USA Insulation for their professionalism, quality of work, and excellent customer service. "

We are proud to be San Antonio's largest residential heating and air conditioning contractor. From the moment you call until the job is done, our goal is your 100% satisfaction. If the job is not done right, we will make it right.

"UPDATE: Amazing how this wonderful review has turned to wishing I never left it or could give them 0 stars. The initial sale was amazing (should’ve known it wouldn’t last). We spent 30k on a brand new unit. 1.5 year later and we find ourselves on day 8 without an AC, now being told it may be another week “and if we don’t hear back from them by Friday, for US to call them again”. Do not be tricked by their initial caring demeanor. It obviously doesn’t seem to last. I have health issues, we have 2 senior dogs and are in Texas. It’s been pushing 90 degrees in our home and they can’t provide a solution to a ‘Cadillac of units’ that THEY recommended and we fell for. I am at a loss. Jon Wayne is the company that installed the unit, now they’re saying the unit ‘is grounded’ and ‘is like a heart that stopped beating’. Crazy that it’s supposed to be a top of the line unit that they compare to a Cadillac for the AC world, yet it stopped functioning after a year. Do yourself a favor and get other options and opinions before trusting them on something as important as cool air in your home. I can’t believe we are dealing with this. Now we’re 30k in, an additional 1k for their ‘warranty’ and still without a working AC. WOW."

Affordable Insulation is a full service insulation contracting company for existing homeowners to find ways to improve the effectiveness in reducing home energy consumption. We specialize in drill-n-fill to exterior walls where no insulation exists, re-insulation of attics to increase R-value and garage door insulation kits.

"Used Affordable Insulation to blow in fiberglass insulation into attic above 3 car garage. They were quick to reply to my initial inquiry and follow up questions. Marc had the estimate to me the same day I contacted them. Their estimate was much more affordable (pun intended!) than another quote I received. I was very pleased with their number and was ready to hire them. The team of Jason, Jason, and Daniel were courteous, friendly and professional. They called ahead and showed up as scheduled. They made quick work of the job. The job came out looking great. Insulation depth was a couple inches deeper than expected so was pleased about that as well. They ensured no insulation was in the overflow drain pans of water heater or AC since that could clog the overflow drains causing them to backup. They cleaned up all excess insulation that had fallen into the garage. Attention to detail was superb. I highly recommend Affordable Insulation."

FAQs for blown in insulation install or upgrade projects in San Marcos, TX

Many major home improvement retailers offer free machine rentals when you purchase a minimum quantity of insulation material, often 20 to 30 bags. These promotions vary by location and season, so calling ahead to confirm current offers is recommended. Be sure to understand any time limitations that apply to these free rentals, as they may restrict you to a specific return window, often 24 hours from checkout.

For most residential attics under 1,500 square feet, a standard consumer-grade blower available at rental centers will provide adequate performance. Larger spaces or projects requiring greater insulation depth may benefit from higher-capacity equipment. 

When consulting with the rental provider, mention your attic's square footage, desired insulation depth, and accessibility conditions to receive appropriate equipment recommendations for your specific situation.

DIY installation saves between $160 and $560 in labor costs for standard attic installations requiring four to eight hours of work. These savings must be weighed against equipment rental fees of $50 to $210 per day and the value of your personal time. For more complex installations like wall insulation, which can require 20+ hours of professional labor (costing $800 or more), the potential savings increase substantially, though so does the project complexity.

While there's a learning curve, most homeowners can master the basics with some practice. Key techniques include maintaining consistent material flow into the hopper, controlling hose direction effectively, and preventing clogs in the system. 

Starting in less visible areas allows you to refine your technique before moving to more prominent spaces. Thoroughly reviewing the equipment manual and watching instructional videos beforehand significantly improves first-time success rates.

Standard rental periods provide 24 hours of use, though specific terms vary by provider. Some locations calculate this as a calendar day, while others track a full 24-hour period from checkout time. Clarify the exact return deadline when renting, and plan your project timeline accordingly. Late returns often incur additional daily charges at the full rental rate, which can quickly increase your project cost if not managed carefully.
