How to Prepare Your Air Conditioner for a Heat Wave

When summer heatwaves hit, your air conditioner works overtime to keep your home comfortable. Without proper preparation, the extreme demand can lead to poor performance or even system failure. Here’s how to prepare your air conditioner and keep it running smoothly through extreme heat.

1. Inspect and Replace Air Filters

One of the simplest and most effective ways to prepare your air conditioner is by maintaining clean air filters. Dirty or clogged filters restrict airflow and force your system to work harder than necessary, increasing the risk of breakdowns. Make it a habit to check your filters regularly, especially during peak summer months. 

2. Schedule Professional Maintenance

Before summer reaches its peak, schedule a professional AC inspection and tune-up. This is a key step to prepare your air conditioner for the heavy demands of a heatwave. During a tune-up, technicians will clean the condenser coils, inspect the fan and motor components, check refrigerant levels, and test for any potential issues. This not only improves performance but also helps prevent mid-summer breakdowns.

3. Adjust Your Thermostat Wisely

Finding the right thermostat setting during extreme heat is about balancing comfort and energy efficiency. Aim to set your thermostat to the highest temperature you can comfortably tolerate. For many households, that means around 78°F (26°C) while at home and 80°F (27°C) when away.

Consider upgrading to a programmable or smart thermostat. These devices allow you to set schedules and optimize cooling based on your habits, the weather, and occupancy patterns, helping you stay comfortable while lowering energy use.

4. Reduce Heat Inside Your Home

Giving your air conditioner some extra help can go a long way. Use these simple strategies to reduce indoor heat and relieve strain on your system:

  • Keep curtains, blinds, and shades closed during peak sunlight hours.
  • Use ceiling fans to circulate air and enhance cooling.
  • Seal gaps around windows and doors to prevent cool air from escaping.
  • Limit the use of heat-generating appliances during the hottest parts of the day.

    Big HVAC purchases can be kinda scary for first time homeowners. I was honestly prepared for the process of replacing our super old furnace and AC to be stressful and confusing, but everyone at Able was amazing and made things anything but! Mike was great at explaining all of the technical details in a way that laypeople like us could fully understand, and he made sure we felt knowledgeable about all of our options, and fully confident with the furnace/heat pump setup we decided on. Installation day went so smoothly, and we're stoked with how everything turned out! Thank you Shaan and Jaime!

    Had a great experience with Able Air. Andre came out for the original call and was great. Explained everything he was doing and the final issue- a broken heat exchanger He got me set up right away with Cyrus who came out and walked me through multiple options at different price points. No pressure sales was great. Finally decided on Daikin furnace and heat pump That’s where Ehsan and his team stepped in to do the install on the Monday. Quick and friendly. Explained the new system and left everything tidy including sweeping up the little bit of white dust from changing out the thermostat. Service was great and can’t wait to have a nice warm house again.
