"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 !"

"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!"

"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!"

Insulation questions, answered by experts

Single-pane windows might let in the cold, but if you’re not ready for a long-term solution or window replacement, there are quick fixes to keep your space warmer. Start by sealing gaps with weatherstripping or caulking around the frame to block drafts. For an extra barrier, apply window insulation film to the glass, trapping an air pocket between the film and the window. Thick curtains or thermal drapes can also help keep the chill at bay. And if you’re in a pinch and looking to get creative, bubble wrap can provide a surprisingly effective layer of insulation—just spritz the window with water and press it on, bubble side in.

No, you should avoid using antifreeze in your outdoor spigot to prevent freezing. Antifreeze can contaminate your water supply and harm the environment. Instead, employ safer and more effective methods for winterizing your spigot, such as draining the spigot and using insulation, to protect it from freezing temperatures.

Insulating an unheated garage can still be worth it. For instance, insulating an attached garage can help with heat loss from your house in general, and it can also make it easier to store electronics in your garage without worrying about them being exposed to extreme temperatures.

If you use your detached garage as a workspace, insulation can still make a difference. Plus, you can use space heaters and a window unit AC to help condition the space while you work without installing heating.

High humidity, bad insulation, warmth from sunlight, and poor circulation are all reasons your home’s hotter inside than out. While this is what you want in the colder months, summer can become unbearable if this is a constant. Try to find the cause, but you need to remember that issues like this require a permanent fix (unless you want to bear down during the summer months).

An outdoor spigot needs some attention before the temperatures begin to drop. Using an insulative cover is just one part of minimizing a frozen spigot and pipes. You’ll also need to shut off the water and drain the spigot, which leaves as little water as possible in the pipes to prevent freezing.
