Tenant has requested to have Air Ducts cleaned, what is my responsibility or legal obligation in Georgia?

Let them know how much it will cost. Then give them the option to pay it via next month's rent.

Not under any obligation. I've had 2 or 3 requests in 35 yrs to do it and no never have. Do your 2 x's a year filter change.

FYI last winter we has a gas furnace that the hi temp limit kept tripping. We swapped everything. Had to call in the camera to go up through the burner chamber to the A coil thinking it was blocked-- nope not it. When we pulled the fan blower to do the camera we saw the squirrel cage on blower-- the slots were pretty much closed from dirt. took it out side washed and reinstalled. worked like a champ.

NE, Studies have shown that having excessive hair pulls the follicles and pulls brain cells further apart, making it take longer to ... oh, no, wait, no, maybe not...

Maybe it was that dihydrogen monoxide gets into so many things, even the ducts in our houses, that we should get it out. One of my rentals had so much that it rusted badly, and stunk! Its in shampoo, too, maybe that's why your hairdresser wants you to get more haircuts, NE. Just lookin' out for your health .

Look up dihydrogen monoxide parody if you want more information.

Renee, it could be tenant is experiencing allergy symptoms, or one family member is experiencing allergy symptoms, and is grabbing at solutions. If it were me, I might offer to come over with my shop vac with drywall filters, and clean the vents. When there, I would look for other sources of allergens. If there is a basement, is it dry, or is it musty? I provide dehumidifiers at my rentals, cuz Wisconsin is a very moldy place, and my houses are located where there is a high water table. Takes some training to get tenants to keep running the dehumidifier, it will raise the electric bill. Maybe this tenant is clean, but, have any tenants previously had cockroaches? Might cock-roach frass ( poo) be hiding behind crown molding, switch plate covers, or that uncaulked crevice between the cabinet and the wall? You, being further south, are probably in full fall allergy season. Is there lots of ragweed growing in the yard?

Now, some of these things are fairly easy fixes, some take more diligence, and some just cannot be controlled. One of my houses, in hindsight, had all of these going on. Tenant's son had lots of allergies, including severe asthma, and my allergies were bothered at that house. I fixed most things while they were there, but only discovered the roach droppings recently when gutting the kitchen, after this family moved. Previous remodelors put a layer of quarter inch drywall over damaged kitchen drywall that was covered in frass, and there was a gap where new drywall met the countertop. I had put a piece of trim covering that gap, but my tenant's family was there when I bought the house, so , how much roach frass were they exposed to, from previous occupants? One of the things I will do during this renovation, now that the house is vacant, is caulk every seam, every gap, and, the wood floors will get a super-cleaning, and three coats of polyurethane. Seal that stuff up?
