Blown In Insulation

5 Benefits of Blown Insulation
Blown insulation offers numerous advantages for both homeowners and businesses. Unlike traditional fiberglass batts, we prefer cellulose blown insulation for its superior efficiency and ease of use. Here are the top 5 benefits:
Higher Efficiency
Blown-in insulation is 22% more efficient than fiberglass batts due to its seamless coverage. Made from recycled newsprint, it’s also an eco-friendly option. Proper attic insulation reduces energy loss, saving on heating and cooling costs.
Quick Installation
Blown-in insulation can be installed quickly, usually within a few hours. Two installers can efficiently cover an entire attic, which would take much longer with fiberglass batts.
Cost-Effective Investment
Blown insulation offers one of the quickest returns on investment. Savings on energy bills will quickly cover the installation costs, providing long-term financial benefits.
Complete Coverage
Cellulose insulation fills every nook and cranny, ensuring thorough coverage of all areas in your attic, including beams, pipes, and wiring, something fiberglass batt insulation can’t achieve.
Noise Reduction
Blown insulation helps dampen noise, making it ideal for attics or spaces used for work or recreation.

EXCELLENT Based on 285 reviews Justin Rose2024-08-15Trustindex verifies that the original source of the review is Google. Emergency service they were able to get out within the hour. Dave the tech was great fixed the issue and double checked everything else. michael harber2024-08-08Trustindex verifies that the original source of the review is Google. Needed to replace a 36 yr old Trane AC and gas heater back in May. We spent 3 days getting quotes from Various Companies, half wanted to sell us what they wanted to sell us (wanted a2 or multi stage unit), the other half didn't even send over a quote or were way to high. As a last ditch we called afew other A/C Companies, Dilmak being one of them. We ended up going with Dilmak and couldn't be happier. We originally wanted a Trane but we're offered quotes for what I requested and what they suggested ( comparable unit by Ruud). The team at Dilmak were not pushy, explained the differences in units and how those units would perform in my home. They were extremely patient, informative and professional. The install went great and quick, their team were able to move my outside unit to a new location and completely install in one day!!!!! They stayed in contact through the whole process including assisting with CPS rebates and that process. Today, 2 months later, I can't be happier, it's 102 degrees outside and my unit is keeping us at temp WHILE cycling through the day, even the neighbors are jealous 🙃 We won't be using anyone for our A/C and heating needs but Dilmak and will be recommending them to our family and friends when the need arises. Thanks Trevor, Mario, install team and office ladies, you're amazing!!!!!! Max Nombrano2024-08-06Trustindex verifies that the original source of the review is Google. Dilmak installed my HVAC unit about 4 years ago and they maintain my system at least twice a year and their service is superior! I always recommend them to all my family and friends! MaxN Donna Dittmar2024-07-30Trustindex verifies that the original source of the review is Google. Awesome technician and office staff! Stayed in contact during the whole process.

They’ve come and serviced our AC unit a handful of times and replaced our coils this summer. I love that it’s always quick to get an appt. Amanda who typically answers the phone is always polite and professional. David has been our favorite technician. His experience makes him so knowledgeable. He went above and beyond.
