3 Post-Monsoon Season Tips for AC Efficiency

2019 Sep 27
Posted in: Air Conditioning

We know you’ve noticed the effects of Monsoon Season (broken trees, flooding, damaged roofs, etc.), but have you ever thought about how Monsoon Season affects your AC system? 

Monsoon Season can be hard on your AC, because of all of the rain and debris these storms bring. 

To keep your AC running efficiently throughout the rest of the cooling season, you should: 

  1. Clean your air filter
  2. Clear your condensate drain
  3. Schedule a maintenance check-up

We’ll dive into each of these in more detail, below. 

To-Do #1: Clean your air filter

As a general rule of thumb, it’s important to switch out your air filter every 1-3 months. However, in the fall, after the Monsoon Season, it’s critical that you check your air filter and change it if it’s dirty.


Monsoons generally kick up a lot of dust and debris that can easily enter your home and usually gets caught in your AC air filter. 

While a dirty air filter may not seem like a huge deal, it can actually cause damage to your AC system and lower your home’s air quality. 

If your filter is clogged, it will restrict the airflow to your AC system, which can cause issues like:

  • Frozen evaporator coil
  • Increased energy bills
  • Less cool air
  • Expensive repairs or replacements

So, to prevent spending money on unwanted repairs or utility bills, check and replace your air filter. 

To-Do #2: Clear your condensate drain

Your AC is not only responsible for cooling your home, but also for dehumidifying it. Your AC removes moisture from your home’s air and drains that moisture out of your home via the condensate drain line. 

During the summer months, when monsoons and other rainstorms are happening frequently, your condensate drain line can become clogged with debris. If this drain line gets backed up enough, it can cause water to overflow into your home around your indoor AC unit. 

At the end of the summer, it’s a great idea to check your condensate drain line and make sure it’s clear of any clogs or debris. 

Here’s how:

  1. Locate your condensate drain. It will be outside of your home and will likely be a PVC pipe that looks like the one pictured above. 
  2. Attach a shop vac to the end of this drain, creating an “airtight” connection between the two with your hand.
  3. Turn the vacuum on for 2-3 minutes. 
  4. Check the shop vac. Notice any debris? You can repeat this a few times to ensure that you’ve sucked out anything blocking your condensate line. 

If you’re not comfortable cleaning your AC drain line yourself, call a professional. If you pay for a maintenance plan, this service may be included. If not, it usually doesn’t cost much to have a technician come and make sure that your drain line is clear and your AC is running smoothly. 

To-Do #3: Schedule a maintenance check-up

Imagine this: You drive your car across the country and by the time you get home, your car is covered in dust, dead bugs, water stains, etc. 

Would you leave your car untouched and drive it to work the next day without washing it or taking it to get an oil change? No way! You would want to make sure that your car was in great shape after a long haul like that.

You should think of your AC in the same way. In areas that are hot, like Phoenix, your AC system works hard to provide you with cool air all summer. On top of that, it’s been hit with dust and rainstorms, which can affect its ability to work efficiently. 

Even if you’re diligent about replacing your air filter throughout the summer, some dust can still get into your indoor AC system and can cause serious issues if it isn’t cleaned out. 

If your outdoor unit is covered in dust, it will struggle to get rid of the heat in your home, which can result in warmer air as well as an increase in cooling bills.

The solution to all of this? Have a professional clean both your indoor and outdoor AC units (and check all working parts of your AC system).

Trust us, if you want an AC system that you can rely on for years to come, maintenance after Monsoon season is a must.
