<p>Long time landlord here. We had a tenant who wanted the A/C ducts cleaned because of daughter’s allergies. They offered to split the cost with us. They were good long-time tenants so we agreed, but we probably would not have done so for new tenants.</p>
<p>The only other time I’ve had duct cleaning is after we did a lot of remodeling to a rental house we own. There was a ton of dust from the construction and the house had been a rental for about 30 years and had never been cleaned. We figured it was probably worth doing but who knows? We used Coit because they had a special going at the time and they were a nationally known company. I think we paid $400 for a 4-bedroom house. They charge based on the number of A/C vents in the house. </p>
<p>I must say that the tenant’s mother is really being a PITA and I would tell her to back off. I prefer to take my time researching repair companies and vendors to make sure I get someone reputable and recommended. If that takes a couple of weeks, so be it. No one’s life is in danger from the problems so you are within your rights to make the repairs on your own timetable.</p>
