The HVAC fan is just recirculating the indoor air through the (inexpensive) air filter (usually not HEPA) and getting any outdoor fresh air from? You would better off using a HEPA type of HVAC filter to purify your indoor air vs. constant ozone treatment, IMO. Ozone | Indoor Air

I was talking to the neighbors, and they told me the lady who lived here was a chainsmokers and she had pets but with her declining health she was not able to get the pets out to go to the bathroom

When she passed, an investment company bought the property and basically remodeled it. I heard they had to grind the concrete floor down because of pet urine.

Supposedly before I bought the place they had the ducts cleaned.

I assume the smell that's in the air is because of cigarette smoke. I am thinking about having a company do an a professional ozone shock treatment. It costs $1350.

Based on my research, it looks like this is a pretty effective route to go but I was just wondering if anybody has ever had ozone shock treatment done in their house and what the result was.

Thanks for the info. That was my initial plan, just buy a 5 gallon bucket of kilz oil base primer and paint the whole house. Maybe I'll try that first. That's only a couple hundred bucks and some elbow grease. Unfortunately, they had already painted the walls so I'm not gonna be able to do any scrubbing. I'm only going to be able to spray a couple coats of primer on the walls and ceiling.

I have one that we used in a previous home where the owners smoked. They smoked outside, but their clothes made the closets smell. Ozone generator completely fixed it.

I am a Home Inspector and I do repairs as well. One of my services is Ozone treatment. It works. No doubt about it, but you need to have enough of it, for long enough for it to work. It requires the home owners to vacate usually at least 6 hours.

If the smell persists afterwards, it is being re-generated by something and there is active mold growth or something going on.
