"Excellent service from true gentlemen! Florida Insulation Systems sprayed foam insulation in both our main house and our guest house. They did a fantastic job and were incredibly clean throughout the entire process. Their pricing is very fair, and Jonathan is a phenomenal communicator. What impressed me most was their follow-up care. Even a year after the installation, we reached out to ask them to check on a few areas. They came right back out and took care of everything meticulously. I highly recommend them for their outstanding workmanship and dedication to their clients!"

"I had an amazing experience with this spray foam insulation company. From the first phone call, they were upfront, honest, and very knowledgeable. The crew showed up exactly when they said they would and walked me through the whole process before starting. They insulated my attic and part of my garage, and the difference was noticeable the same day ? the rooms stay cooler, and the AC doesn?t run nearly as much"

"How can I give 11 stars? This guy saved me from renting a house with mold in the a.c. I hired him to clean a ducts and he pointed out the bad condition of the a.c. unit.. which I didn't notice. he also cleans ducts to an amazing degree of being clean. He installed a U. V. Light to reduce allergies and he has a story about how effective the light works. If you have an a.c. then contact this guy. On time... polite... patient.... and good products"

"Excellent company! We are very satisfied.We have lived in our south Florida house for 25 years. This is our 3rd AC. We were told by the other AC people that it was not possible to get the temperatre to 75 degrees in the heat of summer, in the middle of the day. So, for 25 years we have lived in AC that rose to 82 degrees in the summer. NOT ANYMORE! Comfort zone gave our home the correct sized AC and replaced our old ductwork and gave us better insulation for the attic. Like anything, there were issues that came up like one room did not get the suficient airflow and wasn't getting as cool as the rest of the house. Chris and his team fixed it immediately. Every single issue we had Comfort Zone handled it professionally, quickly and had a great attitude to help us and make sure we were completely satisfied. The best part was they ALWAYS solved the issue. We are very happy that we had our AC installed by Comfort Zone. Chris and the whole team were great. Knowing that we now have a relationship with a company that will be with us for a long time is very comforting. The picture says it all. That is at 2:15 in the afternoon at 90+ degrees outside."

"The best experience I've ever had with a contractor. It doesn't get any better and the project went like clockwork. A superb and respectful crew who labored in the Florida summer heat. I can't say enough good things about Joseph and his employees. Well done. Tom F"

Insulation FAQs, answered by experts

Energy-efficient homes generally have higher appraisals and appeal to buyers.

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.

Insulation is professionally installed by measuring spaces, cutting materials to fit correctly, and placing them without gaps for optimal thermal resistance.

Spray foam insulation doesn’t do well around heat sources. Therefore, You can use spray foam insulation to seal around HVAC boots that penetrate through the drywalls or around where wrapped ducts connect to the boots, but we don’t recommend using spray foam insulation to encapsulate your air ducts. Spray foam insulation on air ducts is also less effective compared to duct wraps.

Although it’s not required, air ventilation in a finished basement can help improve the air quality, prevent moisture and mold issues, keep musty odors away, and also maintain the air quality throughout the rest of your home. Proper ventilation will help maintain the value of your investment in finishing your basement. Try basement ventilation methods like installing vents or a dehumidifier for best results.
