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 attic insulation installation projects in San Marcos, TX
The best attic insulation depends on where you live, the project stage, and your budget. New builds often benefit from structural insulated panels for top-tier efficiency, while homes in very warm regions can see big cooling savings with reflective insulation. Blown-in, loose-fill, and spray foam all excel at filling odd spaces in finished attics. Talk with a certified local pro to match the material to your climate, space, and wallet.
You’ll only need a licensed electrician if the project calls for moving existing wiring or adding new fixtures. For straightforward insulation jobs, your insulation installer can work around current cables. That said, never start insulating until a pro has checked any questionable wiring. If you suspect damaged or outdated circuits, book an electrician first to keep the project—and your home—safe and code-compliant.
Without air sealing, even the best insulation can underperform. Gaps let heated or cooled air leak out, forcing your HVAC system to work harder and driving up energy bills. Sealing those cracks before adding insulation locks in conditioned air, keeps moisture at bay, and helps the new material hit its full R-value. Ask your insulation pro to tackle sealing first so you enjoy consistent comfort and lower monthly costs.
Among readily available options, structural insulated panels and rigid foam boards top the charts with R-values that can reach 8.0. They’re ideal for new construction or very cold climates where maximum thermal resistance matters most. If you live in a milder zone, blown-in or loose-fill insulation may deliver plenty of performance at a lower price. Weigh the upfront cost against energy savings—and lean on a local pro’s guidance—to pick the smartest fit.
