Both of my dogs have medium size hair and they said twice during the year.
- The dogs shed when it is the spring months and then they shed again in the fall.
There is a lot of hair inside of my tiny house, so I have to be certain that the AC is not affected by the problem. Excessive pet hair can cause a number of issues with the heating and cooling system. Pet hair can block the air filter and cause a problem with air flow to the machine. Pet hair can cause damage to internal machinery and it can cause problems with the electrical work as well and possibly lead to a fire. Dirty air filters should be cleaned at least once each month. I have a small portable AC unit. It has an air filter on the side and two more larger air filters on the back of the machine. The AC unit has the capability of being a dehumidifier as well. Because my two dogs shed frequently, I constantly need to be on top of the maintenance on the portable AC unit. Each one of the air filters needs to be cleaned weekly. I noticed a lot more dirt and dog hair on the filters if I wait 2 weeks and I think that causes some problems when I run the portable AC unit. When the air filters are dirty, I feel like the machine runs for a lot longer and it seems to take longer for the portable AC to get to the right temperature.
