Why Heatwaves Matter More Than Ever

In recent years, summer heatwaves have gone from rare events to regular threats. The number of days above 90°F has increased significantly in many U.S. cities over the past few decades. As climate extremes become more common, your home's cooling system isn't just a comfort upgrade—it's a critical safety tool.

When extreme heat strikes, an efficient HVAC system can protect your family from heat-related illness, reduce indoor humidity, and help you avoid costly emergency repairs. But without the right preparation, even newer systems can fail under stress. This guide from HVAC365 explains how to get your system ready, how to recognize common risks, and what you can do right now to stay cool and safe this summer.

What Heat Does to Your HVAC System

High Temperatures = Higher Stress

When outdoor temperatures climb past 95°F, your HVAC system has to work significantly harder to maintain indoor comfort. That leads to:

• Longer run times
• Higher energy bills
• Faster wear and tear
• Increased risk of breakdowns

Even minor issues, like a clogged filter or dirty coils, can spiral into major system failures when demand is high. That’s why preventive maintenance is more important in summer than any other time of year.

Heatwave Red Flags to Watch For

• Warm air coming from vents
• Constant cycling or failure to reach set temperature
• Ice forming on outdoor unit
• Sudden spikes in your energy bill

These symptoms often indicate airflow issues, refrigerant problems, or stress-induced part failure—all common during heatwaves.

How to Prepare Your HVAC System for Summer

Step 1: Schedule a Pre-Season Tune-Up

A licensed HVAC professional can inspect and clean your system before temperatures peak. During a typical service call, they'll check:

• Thermostat calibration
• Refrigerant levels
• Duct airflow
• Electrical connections
• Condenser and evaporator coils

Step 2: Change Your Air Filter

Dirty filters block airflow and force your system to work harder. Change filters every 30 to 60 days during peak use to maintain efficiency and indoor air quality.

Step 3: Clear the Area Around Your Outdoor Unit

Make sure there's at least 2 feet of clearance around your AC condenser. Remove leaves, grass clippings, and other debris to help it operate at full capacity.

Step 4: Check Your Thermostat Settings

Set your thermostat to a consistent temperature and avoid frequent manual adjustments. Smart thermostats can help maintain efficiency by learning your schedule and preferences.

Step 5: Seal Air Leaks

Inspect windows, doors, and ducts for leaks that let cool air escape. Sealing these areas can reduce energy waste and lighten the load on your HVAC system.
