Running a guesthouse might be the most challenging business I have run in my entire life. I keep the air conditioner well maintained and change the Ac filter every month without fail. I even signed up for the air conditioning system home services program to make sure I would be able to get an HVAC technician to come by in case we had any emergencies. All my HVAC maintenance efforts were trashed when a couple of guests came over and brought three very furry pets who were all smokers. I like to trust my guests to follow the rules so I do not hover around to make sure they follow every little one, but in this case, I wish I had hovered. Another family was coming in within a day after they checked out, but the entire house smelt of smoke, and nothing I did to clean it helped. I opened the windows the moment they left and turned on the HVAC unit longer than I did on other days to see if the air quality would improve, but nothing seemed to help. I gave in and called an HVAC professional from the local HVAC company to come to help me sort the issue. The eventual solution was that the smoke was trapped within the ductwork, and we’d need to clear it out. There was also fur left all over the house, yet my next clients asked for a fur-free house. I had to have the air duct cleaned to avoid the risk of igniting any allergies. While I did not have to do any Ac repair, paying for help with indoor comfort before my next guests checked in was an expense I had not expected and I unfortunately could not trace my inconsiderate guests and bill them. Worst experience so far.
