Stop losing money through your attic. Professional insulation installation reduces energy bills by up to 20% and keeps your home comfortable year-round.
Texas summers push temperatures well above 100°F, while winter cold snaps can plunge into the teens. Without proper insulation, your HVAC system works overtime — and your energy bills prove it.
Most North Texas homes, especially those built before 2000, have inadequate or deteriorating attic insulation. The Department of Energy recommends R-49 insulation for our climate zone, but many homes have R-19 or less. That gap costs you money every single month.
LEX Air Conditioning provides professional insulation installation for attics, walls, and crawl spaces throughout Dallas-Fort Worth. We assess your current insulation, recommend the right solution for your home, and install it properly — so you start saving immediately.
If you notice any of these issues, your insulation may be inadequate, damaged, or deteriorating.
If your heating and cooling costs keep rising despite efficient HVAC equipment, poor insulation is likely the culprit.
Rooms that are noticeably hotter or colder than others often indicate insulation gaps or insufficient coverage.
Feeling cold air near walls, windows, or floors — even when closed — suggests air leaks and poor insulation.
Ice forming on your roof edges indicates heat escaping through poor attic insulation and melting snow.
Older homes often have outdated or deteriorated insulation that doesn't meet current energy codes.
Old insulation can harbor dust, mold, and allergens that affect your indoor air quality and health.
Not sure about your insulation? We offer free attic evaluations to assess your current R-value.
Get a Free EvaluationWe offer multiple insulation solutions to match your home's needs and your budget.
The highest R-value per inch. Creates an air-tight seal that blocks moisture, air infiltration, and provides superior thermal performance. Ideal for attics, crawl spaces, and hard-to-reach areas.
Loose-fill fiberglass or cellulose blown into attics and wall cavities. Excellent coverage, fills gaps easily, and cost-effective for large areas. Perfect for adding insulation over existing material.
Pre-cut fiberglass or mineral wool panels designed to fit between studs and joists. Cost-effective, fire-resistant, and ideal for walls, floors, and ceilings in new construction or renovations.
Specialized insulation for under-floor areas that prevents cold floors, reduces moisture, and improves overall home comfort. We use materials rated for high-humidity environments.
Before adding insulation, we seal air leaks around penetrations, ductwork, and gaps. This maximizes insulation effectiveness and prevents conditioned air from escaping.
Professional insulation solutions for warehouses, offices, and retail spaces. We assess your building's needs and recommend the most cost-effective approach for energy savings.
From evaluation to installation, here's what to expect when you work with LEX.
We inspect your attic, measure current R-values, identify air leaks, and assess moisture issues. You'll get a detailed report and honest recommendations.
Based on your home's needs, we recommend the right insulation type and R-value. You'll receive transparent pricing with no hidden fees.
If needed, we remove old, damaged, or contaminated insulation. We seal air leaks and ensure proper ventilation before installing new material.
Our certified installers apply insulation to the recommended R-value, ensuring complete coverage with no gaps. We clean up thoroughly when done.
Quality insulation delivers returns that go far beyond energy savings.
Proper insulation can reduce heating and cooling costs by 15-20%. Most homeowners see payback within 3-5 years through monthly energy savings. Your HVAC system runs less, saving wear and extending its lifespan.
No more hot spots in summer or cold drafts in winter. Quality insulation maintains even temperatures throughout your home, eliminating the rooms that never feel quite right.
New insulation combined with air sealing reduces outdoor allergens, dust, and pollutants entering your home. It also eliminates old insulation that may harbor mold, pest debris, or degraded materials.
Energy-efficient homes sell faster and for more money. Upgraded insulation improves your home's energy rating and appeals to buyers who understand ongoing utility costs.
Insulation costs vary based on your home's size, current insulation condition, accessibility, and the type of insulation you choose. Here are typical price ranges for Dallas-Fort Worth homes:

"Our summer electric bills dropped by over $80/month after LEX added insulation to our attic. We'd been in our 1985 home for 10 years with no idea how much money we were losing through the roof. The team was professional, clean, and finished in one day."— Mark T., Richardson, TX

Common questions about home insulation in North Texas.
According to Energy Star, North Texas homes should have R-38 to R-49 insulation in the attic. If your attic currently has 3-4 inches of insulation (approximately R-11 to R-15), you need to add more to meet current recommendations. Uninsulated attics should be brought to R-49.
It depends on your specific situation. Blown-in insulation is cost-effective for adding coverage to existing attics. Spray foam provides the highest R-value per inch and creates an air barrier — ideal for new construction or major renovations. Batt insulation works well for walls and accessible spaces. We'll recommend the best option during your free evaluation.
Most residential attic insulation projects can be completed in one day. Larger homes, spray foam installations, or projects requiring old insulation removal may take 1-2 days. We'll provide a timeline with your quote.
Not always. If existing insulation is in good condition (no moisture damage, pest contamination, or compression), we can often add new insulation on top. However, if old insulation is damaged, contaminated, or inadequate, removal is recommended before installation.
Yes, when installed correctly by trained professionals. Spray foam is inert once cured (usually within 24 hours). Our certified installers follow proper safety protocols, use quality materials, and ensure proper ventilation during application. DIY spray foam installation can be risky, which is why professional installation is recommended.
Most homeowners see 15-20% reduction in heating and cooling costs after upgrading attic insulation to recommended levels. Actual savings depend on your current insulation, home size, HVAC efficiency, and usage patterns. Many homeowners see payback within 3-5 years.
Yes! The federal Inflation Reduction Act offers tax credits for qualifying home insulation improvements. Some utility companies also offer rebates. We can help you understand available incentives and provide documentation for your tax professional.
Absolutely. Poor insulation forces your HVAC system to work harder to maintain temperatures, increasing energy consumption, wear, and the likelihood of breakdowns. Upgrading insulation often extends HVAC lifespan and reduces repair frequency.
