How Summer Heat Impacts HVAC Efficiency & What You Can Do Now

Summer’s soaring temperatures can put your HVAC system to the test, impacting its efficiency, reliability, and your energy bills. Understanding these effects—and knowing what you can do—will help you keep your home comfortable and your costs under control. If you’re searching for an “HVAC company near me”, P&M Mechanical is here to guide you through the essentials.

Increased Strain on Your System

• Extreme heat forces your HVAC to work harder to maintain cool indoor temperatures. The greater the difference between outdoor and indoor temperatures, the longer your system runs, increasing wear and tear.
• Overworked components can lead to reduced cooling performance, higher energy consumption, and even system breakdowns.

Higher Energy Bills

• Energy usage spikes during heatwaves. Even high-efficiency units struggle if filters are clogged, coils are dirty, or airflow is restricted.
• Small inefficiencies—like air leaks around windows or doors—become more costly in extreme heat, as your system works overtime to compensate.

Risk of Overheating and Malfunctions

• Continuous operation in high temperatures can cause overheating of critical components like compressors and fan motors, sometimes resulting in system shutdowns or damage.
• Most AC units are designed for temperatures below 95°F; sustained operation above this threshold increases the risk of breakdowns.

1. Schedule Preventive Maintenance

• Regular professional maintenance keeps your system running at peak efficiency and helps prevent unexpected breakdowns.
• A trusted HVAC company like P&M Mechanical can inspect, clean, and tune your system for optimal performance.

2. Change Air Filters Frequently

• Dirty filters restrict airflow, forcing your system to work harder and reducing efficiency.
• Replace filters every 1-3 months during peak summer use.

3. Seal Air Leaks

• Check for gaps around windows, doors, and attic hatches. Sealing these leaks keeps cool air in and hot air out, reducing the load on your HVAC.

4. Optimize Thermostat Settings

• Set your thermostat a few degrees higher during peak hours or use a programmable/smart thermostat to pre-cool your home in the morning and ease up during the hottest part of the day.
• Avoid drastic temperature swings, which can increase energy use.

5. Insulate and Shade

• Proper attic insulation helps maintain indoor temperatures and reduces the strain on your system.
• Use blinds, curtains, or shades to block direct sunlight and keep rooms cooler.

6. Clean Condenser Coils

• Outdoor condenser coils can accumulate dirt and debris, reducing efficiency. Regular cleaning improves performance and extends system life.
