Attic insulation in Jacksonville
Why an AC Company Does Attic Insulation
In most Jacksonville homes the air handler and the ducts are in the attic. On a summer afternoon that attic is far hotter than the house, and the insulation on the attic floor is what keeps that heat out of the rooms below. When it is thin or packed down, the AC runs longer to keep up.
We are in attics on most of our jobs, so we can tell you how much insulation you have and whether more is worth it. If it is, we blow it in.

Signs you could use more
Does Your Attic Need More Insulation?
You can check most of these from the attic hatch with a flashlight.
Rooms under the attic run hot
Bedrooms and hallways under the attic are warmer than the rest of the house in the afternoon, and the AC runs long to catch up.
You can see the joists
If the tops of the ceiling joists show above the insulation, the layer is thinner than the joists are deep.
It is packed down or patchy
Insulation gets crushed and pushed aside by past work in the attic: AC changeouts, wiring, roof repairs. The gaps are where heat gets through.
Nobody has looked in years
If you don’t know how deep yours is, that is the first thing we measure.
How it works
How a Blown‑In Job Goes
We look first
How deep the insulation is now, whether it is dry, the ducts and the air handler, and anything the new layer would bury.
You get the price
The price for the whole job before any work starts. Financing is available.
We blow it in
An even layer over the attic floor to the depth we agreed, kept clear of the soffit vents. We check the depth and clean up.

JEA attic insulation rebate
JEA has run a rebate for residential electric customers who add attic insulation. As JEA describes it, it pays $0.20 per square foot, up to $200, for attics with less than R‑15 (about 5 inches) that are brought up to R‑38. The rebate is applied through a JEA pre‑qualified contractor.
The terms and deadlines change with JEA’s program year. Check JEA’s page before you plan around it. We don’t promise rebates.

Attic insulation FAQ
Questions About Attic Insulation
Straight answers, no jargon.
How much does attic insulation cost in Jacksonville?
It depends on the size of the attic, how much insulation is up there now, how deep it needs to go and how easy the attic is to work in. We look first and give you the price before we start. Financing is available.
Can I get a JEA rebate for attic insulation?
JEA has run an attic insulation rebate for its residential electric customers. As JEA describes it, it pays $0.20 per square foot, up to $200, for attics with less than R‑15 (about 5 inches) of insulation that are brought up to R‑38, and it is applied through a JEA pre‑qualified contractor. The terms and deadlines change with JEA’s program year, so check JEA’s attic insulation rebate page before you count on it. We don’t promise rebates.
Will more insulation lower my power bill?
It cuts the heat that comes down into the house from the attic, so the AC has less to remove. How much that saves depends on how much insulation you have now, so we won’t quote you a number. If your attic already has a full layer, more won’t change much, and we’ll tell you that.
What R‑value should a Jacksonville attic have?
Jacksonville is in climate zone 2. ENERGY STAR recommends R‑38 when you are adding to an attic that already has 3 to 4 inches, and R‑49 when the attic has none. JEA’s rebate also uses R‑38 as its target. We measure what you have before we say how much to add.
Can you add insulation on top of what I already have?
Usually, yes. If the old insulation is dry and in fair shape, we blow the new layer over it. If part of it is wet, moldy or damaged by pests, the cause needs fixing first, and we’ll show you what we found.
Is blown‑in insulation better than batts?
For adding to an existing attic, blown‑in is the usual choice. It fills around joists, wiring and ducts in one even layer. Batts have to be cut to fit around those, which leaves gaps.
Do you install spray foam?
No. We install blown‑in insulation only.
Why does an AC company do insulation?
Because in most Jacksonville homes the air handler and ducts are in the attic, and we are up there on most jobs. The insulation on the attic floor decides how much attic heat reaches the rooms the AC is cooling.
