"Last summer, even with the AC running constantly and the thermostat set at 72 degrees, the temperature inside the house would reach 80 degrees or higher. This summer is much better; the thermostat is set to 70 degrees, and the house actually stays at 70. Our electric bills are also reflecting this improved energy efficiency. Thank you Dillon, NxT Level Insulation for the outstanding work and exceptional customer service."

"Top notch customer service.  They explained to me line by line all the rebates I can get through the utility company.  The biggest being the green energy tax credit that was about to expire by the end of the year if I were to install a solar attic fan through them, which I had no idea.  The rebates and credits really help me make the decision to get it done now.  So glad we did. Technicians were on time, in and out clean and efficient.   The solar attic fan they installed made a huge difference in our attic.   They were able to retrofit it over our existing vent hole which was very nice because we didn't have to cut a new hole in our roof.  All and all just wonderful experience.  The new insulation made our home much more comfortable now."

"My son recently purchased an older home that had very little attic insulation. After Rob's team finished adding fiberglass insulation the A/C turned off almost immediately and the home remained at 74 degrees even though it was over 100 that day. I was very impressed and plan to have them come inspect my attic next !"

"They were a bit over the rest of the company’s that I had out. But the pease of mind that I had knowing that they were going to do it right was worth it. During the bid Mike answered all my questions before I was even able to ask them. Made a great impression on me. They also worked well with me removing my old insulation myself. PLUS , they hauled off the old stuff for me at a great price!! Thx guys!"

"We had two separate appointments, one for duct cleaning and one to add insulation. Both crews were professional, clean, efficient and polite. They were all responsive to questions and feedback. I will definitely hire Climate Doctors again in the future and will have no problems referring them to friends, family, co-workers, and my Real Estate clients!"

Insulation questions, answered by experts

The lifespan of crawl space insulation depends on how well you maintain your insulation and the type of insulation. Fiberglass will need replacing every 15 to 20 years on average if you don't have a vapor barrier in place. If you do have vapor barriers in place, then your insulation could last much longer. Spray foam insulation can last anywhere from 80 to 100 years. 

Yes, cold walls are a common indicator of poor or inadequate insulation, especially if the walls feel significantly colder than the air in the room. This suggests that heat from your furnace is escaping rather than being retained. The issue could be that the walls have no insulation, or that the existing insulation is old or has been damaged by water, moisture, or pests. Your best course of action is to hire a professional to investigate. An insulation contractor can determine if you need to add or replace insulation and can often perform the work without creating large holes in your drywall. If you suspect the problem might also be related to your heating system's performance, an HVAC technician can take a closer look.

Ductwork sweats due to a temperature difference between the air inside the ducts and the surrounding air, similar to how a cold drink develops condensation in the heat. This sweating is a sign that your HVAC system is not operating at peak efficiency. The best way to keep ductwork from sweating is to wrap it in proper insulation, which also improves your system's energy efficiency. Another option is to close off your crawl space and install a dehumidifier to dry the air and lower its dew point.

If the temperature outside is around 90 or 100 degrees with the sun beating on your home’s roof, it’s common for the attic temperature to reach 150 degrees or more. This excessive heat shows the importance of having a radiant barrier in place along with insulation. The radiant barrier reflects the heat entering the attic back upward, keeping your home’s temperature more consistent.

While carpet over carpet may provide some additional insulation and soundproofing benefits, it's not as effective as other methods. Layering carpets can add a modest buffer against noise and temperature fluctuations, but it's limited compared to installing thicker carpet padding or using specialized soundproofing materials. For optimal floor insulation and soundproofing, consider alternative solutions tailored to your specific needs and budget, such as adding additional padding or soundproofing underlayments beneath the carpet.
