Most winter comfort complaints come back to the same few gaps in the house. We test to find which ones your home has.
Drafty rooms
Air leaking in around attic hatches, rim joists, plumbing and wiring holes, and knee walls. Air sealing stops it at the source.
Cold floors
Floors over an uninsulated or damp crawlspace lose heat all winter. Crawlspace insulation and encapsulation fixes it.
One room always hotter or colder
Rooms over garages, bonus rooms and upstairs bedrooms often have thin insulation, air leaks or leaky ducts.
High heating and cooling bills
If the house leaks, your system runs longer to keep up. Sealing and insulating lets it do less work.
Thin or damaged attic insulation
Settled, thin or damaged attic insulation can be added to or replaced to bring the attic up to the right level.
HVAC that runs and runs
A system that never seems to catch up may be fighting the house, not failing. HVAC repair & installation.
Considering foam for rim joists, a crawl space or a roof deck? Compare open- and closed-cell spray foam options. Not sure where your home is losing energy? A whole-home energy audit measures it, and our weatherization services cover sealing, insulation and crawlspace work together. We work across Gordon, Bartow, Whitfield, Floyd and neighboring counties.
The Whole Home Matters
Your heating and cooling system doesn’t work in isolation. Insulation, air leaks, crawlspaces, ductwork and windows all influence how much of the air you pay to heat or cool stays in your home. Insulating and sealing the house can be one part of improving whole-home comfort.
Home Comfort
These parts work together.
InsulationSlows heat moving through attics, walls and floors.Air sealingStops air leaking through gaps and cracks.CrawlspaceHelps keep damp, unconditioned air out from below.
DuctworkCarries conditioned air to every room.

Your HVAC system is only as good as your home's envelope. That's why Anderson Heating, Air & Insulation became BPI certified — to measure, test, and fix the entire home, not just the equipment.
"I realized I had to own the whole house power bill — not just swap the box." John Anderson, Founder
Air Sealing First
Air leaks can carry heat and moisture through gaps that insulation alone does not stop. A whole-home assessment identifies bypasses, duct leakage, and existing insulation before work is scoped. In many homes, sealing accessible leaks and then installing insulation to the appropriate level produces a more reliable comfort result than adding insulation without diagnosis.
How We Work
Real air sealing means crawling into the spots most contractors won't — crawlspaces, knee walls, rim joists, attic hatches. Our BPI-certified crews measure leakage with a blower door before and after so you see proof, not promises.

FAQ
Proper insulation and air sealing often meaningfully reduce heating and cooling costs. Many of our customers see the payback through lower utility bills.
Air leaks can carry heat and moisture through gaps that insulation alone does not stop. A whole-home assessment identifies bypasses, duct leakage, and existing insulation before work is scoped. In many homes, sealing accessible leaks and then installing insulation to the appropriate level produces a more reliable comfort result than adding insulation without diagnosis.
Rooms over garages, bonus rooms and upstairs bedrooms are the usual suspects. They often have thinner insulation, more air leaks or leaky ductwork feeding them. Testing the house shows which one it is, so the fix goes where it's needed.
Not always. Insulation that's dry and intact can often be added to. Insulation that's wet, moldy, heavily compressed or contaminated is usually better replaced. We check its depth and condition, and seal attic air leaks first either way.
BPI (Building Performance Institute) certification means we use scientific testing — blower door tests, infrared cameras, and pressure diagnostics — instead of guessing. We measure before and after.
Yes. We specialize in sealed, conditioned crawlspaces with vapor barriers, insulation, and dehumidification. This stops moisture, mold, and makes your home healthier and more efficient.
Most attic insulation jobs are completed in 1 day. Whole-home air sealing and wall insulation typically take 2-4 days depending on the size and condition of the home.
Absolutely. Your HVAC is only as good as your home's envelope. We often recommend insulation and air sealing before or alongside new equipment so you get the full efficiency benefit.
