Benji Studt28 October 2023I had All Thermo perform a comprehensive attic cleaning and replace the AC ductwork. They began by removing all the old insulation, sealing the attic floor to reduce air transfer, disinfecting the entire attic space, then replacing the old ductwork and finally installing chemical-free insulation. This has greatly enhanced our indoor air quality and led to a reduction in our FPL bill. Our home now feels entirely rejuvenated. This is the second time we’ve had All Thermo come help us…we also had them out to our old condo almost 10 years ago. Same staff and same great work. These guys exemplify the difference of hiring a small, family owned company that relies on word of mouth and personal referrals.
Christian Thibaut23 October 2023All Thermo performed AC ductwork sealing, attic air sealing and added new chemical-free attic insulation to my home. We have noticed our Air Conditioner running a lot less and a reduction in our FPL bill. I’d highly recommend this family owned & operated business!
cher kay20 October 2023Hi Jason. Just wanted to let you know… we just got a full months power bill since you installed the insulation and our power consumption went from 1,000 kWh the year prior to 425 kWh this month, with a higher average temperature outside. This is the lowest power bill we’ve had. Amazing result!!! Thank you!
Linda Jayne27 September 2023Very professional. Do what they say and clean up afterwards! Highly recommend them.
Madeline Vernese26 August 2023Jason and Christian were excellent to work with. They communicated to me throughout the entire process. A huge plus was both Jason and Christian arrived ON TIME. Their prices are very competitive with other insulation companies. Jason was able to answer all of my questions about the type of insulation they use and expected lifespan. No mess was made at all during installation. You couldn’t even tell they were in my home when they were done. It’s been three days since our house received ten inches of insulation over the existing 3-4 inches. It’s been so nice to come home to a house that has been able to maintain its temperature! Previously our two year old AC could not keep up. It would be set to 75 and it would be 78 in the house during peak hours. Now when I come home it’s 75 degrees inside as it should be. Our AC seems to be running much less. I’m looking forward to hopefully saving some money on my next electric bill.
Tim McLaughlin18 August 2023All Thermo responded promptly to my inquiry, did a good job on the added insulation. Recommend them to anyone who wants to beat the heat
denise thomas11 August 2023Buy a house they said... Lord have mercy it has been one thing after another, just when you think your are done, you get a kick in the pants! Dont get me started on the contractors here in Florida with poor response, poor workmanship and poor customer service, are you with me so far? Well the journey begins! Let me set this up for you. I put a new roof on approx. June 2022, hang on, I'm going someplace with this.! I have had 5 roof leaks! Yeah I said it, did I do a review on that company? No but it is coming you can count on it. So I thought putting in insulation in my attic would be good for the house and my AC unit. I called 2 companies-only one returned my call. Why only 2- I read the reviews. I did my research. The question is put the new insulation on top of the old or remove the old and than the new. I went with the latter one. Than I am hearing horror stories of feet, hands coming through the ceiling! I asked this company "does this happen?" Yes they said but not often they are very carful (I heard this before) I HAVE A STOMACHACHE! Well Jason (Scooter) who showed up, was very professional, knew what he was talking about, when I asked questions he explained everything to me so I understood. Ok I thought this was too easy. Now Christian and the crew showed up (here it is-this is what I was waiting for) Nope Christian was a duplicate of Jason! WAIT WHAT...what is happening here? Work was completed in 2 days ! They cleaned up my garage, and driveway like no one was there! The work was perfect absolutely perfect! Tears of joy ladies and gentleman ! Tears of joy! I want to adopt this entire family! Yes this is a family owed business! Oh Ms Thomas you have a small roof leak! And there it is! Leak number 5. All Thermo & your staff I want to thank you so much for all your hard work, working in the attic with this heat. Are you hiring? Hire Them you WIIL NOT BE SORRY, tell them I sent you!
Ashleigh Bullivant27 July 2023Great company and awesome crew. Thank you!
Barb15 July 2023Everything quick and efficient..from getting a quote, setting up appointment, to installation. Process clearly explained. No mess. Delighted with results. Wish I had done this ages ago. AC no longer struggling with this heat. Highly recommend.

The Best Types of Attic Insulation: Blown, Foam, and Batts to Insulate
What is Attic Insulation?
Attic insulation is a crucial component in your home’s energy efficiency. It involves using materials like fiberglass, cellulose, or spray foam to prevent heat loss from your home. Types of attic insulation include:
- Loose-fill Insulation: Made of fiberglass or cellulose, it can easily fill the attic’s nooks and crannies.
- Batt and Blanket Insulation: Popular among DIY homeowners, this insulation, made of fiberglass, mineral, or rock wool, fits between joists or wall studs.
- Spray Foam Insulation: Typically applied during home construction, it often requires professional setup.
These materials all have different R-values, which indicate their ability to resist heat transfer. The better the attic insulation R-value, the more effective the insulation.
The Importance of Attic Insulation
1. Proper insulation can reduce energy costs and improve home comfort.
Efficient attic insulation is a smart way to lower energy costs and increase home comfort. It’s a straightforward process that has substantial benefits.
- Proper attic insulation helps reduce energy wastage by creating a barrier that prevents indoor heat or cold loss.
- It plays a significant role in maintaining a comfortable home temperature, keeping it warmer in winter and cooler in summer.
- It helps you save up to 10% on total energy usage, leading to reduced energy bills. Experts suggest that insulation can shave 10 to 50% off your heating bill.
- A well-insulated home keeps your HVAC system from excessive workload and unnecessary wear and tear.
- Besides energy efficiency, it improves indoor air quality by preventing outdoor pollutants from entering the home.
- It also safeguards your home against moisture buildup, preventing harmful mold growth.
Consider having an energy audit for precise insulation needs. It’s an investment that pays off in comfort and cost savings.
2. Insulation can also be used to prevent moisture damage and improve home safety.
Insulation isn’t just for comfort—it’s your front line defense against moisture damage in your home. By fixing roof leaks, you nip the problem in the bud since water dampens insulation, making it an easy target for mold and mildew.
- Always box out light fixtures when insulating. Remember, some insulation materials can pose a fire hazard if they touch or cover recessed lights.
- Properly directing exhaust fans and vents towards the outside is crucial. It’s a common mistake to vent exhausts into the attic space, which can lead to moisture accumulation and ruin your insulation.
- Be aware of where to install insulation. In older homes especially, careful placement ensures moisture doesn’t get trapped, preventing mold and ensuing wood rot.
- If you’re using blanket insulation, be sure to cut spaces around obstructions like pipes or ducts. Compressed insulation loses its effectiveness.
Lastly, attic insulation is worth a mention. It’s key to controlling energy loss, both hot and cold. Without it, you might lose up to 85% heat in winters! And come summer, your attic could turn into a heat reservoir pushing up your home temperature. So, insulating your attic not only saves on your energy bills (by a substantial 15% in fact) but also enhances the longevity of your HVAC system by reducing its workload. Plus, it’s an effective way to keep outdoor pollutants out, thereby improving indoor air quality.
Here are few points on home safety:
- The location of insulation matters. Avoid placing it over air intake vents, exposed electrical connections, or heat vents. These can circulate harmful particles or even cause a fire.
- Moisture-soaking insulation in old houses and wooden shingled ones usually leads to molds and rotten wood. Extra caution during installation can save a lot of trouble.
- Don’t play squeeze with your insulation. Compressing it around obstructions like pipes reduces its effectiveness. Instead, cut space in the insulation to provide a comfortable fit around these objects.
That said, remember not to soup up just anywhere. Be mindful, do your homework, and insulate safely!
