Your filters need to be changed every 3-6 months depending on your filter type.  There are a few filters that last a year.   If your filter is not changed and is dirty your AC will have to work much harder to cool and most likely will not be able to because of the lack of airflow through a dirty filter.  A dirty filter basically suffocates your system.  You should It is recommended that you put one cup of Clorox in your drain line to prevent clogging which could lead to ceiling damage should it.


Air Conditioner Maintenance in Plano, TX2. Clear your outdoor unit

Your outdoor condensing unit is prone to get leaves and debris inside the unit.  You should clean the leaves out and wash the coils with water to clear any dirt that could have been sucked in. Why? Your outdoor unit’s main job is to collect all the heat that was removed from the air inside your home. Then, the unit “dumps” all that heat into the outdoor air.

BUT if the outdoor unit is covered in dirt or stifled by dirt and debris, it will struggle to dump all that heat. Think of this as trying to cool off a hot bowl of soup but there’s an airtight lid over the bowl. Doesn’t work very well does it??  The accumulated debris can significantly reduce the efficiency of your air conditioning unit and dramatically raise your utility bills.


Thermostats in Plano, TX3. Check your thermostat settings.

Make sure that you switch your thermostat from “heat” to “cool”.  You would be surprised at the amount of calls we get for this very reason.  You should also have the fan setting on “auto”. Setting your thermostat fan to ON means that it will run constantly—even when your A/C isn’t.  This will make your electric bill higher and will make your home humid.


4. Schedule your routine maintenance.

 “But why would I get maintenance now? I haven’t even run my A/C yet!”

We know and that’s the point. When you schedule A/C maintenance before the heat gets here, you’re making sure that any small problems are resolved before the A/C starts running non-stop. Scheduling a maintenance visit before you use you’re A/C prevents those small problems from turning into larger problems and compromising your comfort when it need it most – in the  middle of the Texas summer!
