1 thing you should never, ever do is forget to change the air filter of your central heating and air conditioner unit.
You see, your central heating and a/c system relies on the official change of the old air filter to keep the ductwork wiped clean and to keep the air flow going strong. When you do not change the old air filter in your central heating and a/c on a biweekly to bi biweekly basis this is when things can get to be rough for your heating and cooling component and could potentially lead to a huge Heating, Ventilation and A/C emergency or your central heating and a/c completely splitting down entirely. This is the reason why it is important to constantly keep up with the increase of the air filter within your central heating and a/c unit! If you have to, make yourself a note. This is what I always do. I have a note on our calendar for each day of each month that the air filter to the central heating and a/c components needs to be changed out. I even have a notice on our cell iPhone to remind me when it is time to change the wonderful but dirty air filter of our central heating and a/c unit. The a single time I forgot to change our old air filter of our central heating and cooling system for a few months I ended up needing to call for heating and air conditioner services from our local Heating, Ventilation and A/C dealer. This was not great!
