Most Common Summer HVAC Issues and How to Prevent Them

Estimated Read Time: 3 minutes

Summer’s here—and so is the demand on your HVAC system. With higher temperatures and longer cooling cycles, it's no surprise that many homeowners experience HVAC issues during this season. At Wisler Plumbing, Heating, Cooling & Electric, we understand how important it is to keep your home comfortable, and we’re here to help you prevent those unexpected breakdowns.

Common Summer HVAC Issues

1. Insufficient Cooling One of the most common complaints we hear during the summer is that a system isn’t cooling effectively. Whether it’s due to clogged filters, low refrigerant, or aging components, our team is trained to assess the situation honestly and efficiently. As one of our customers, Richard M., noted: “They give you real information about what's going on and don’t try to upsell you.”

2. System Overload Your HVAC system runs longer and harder in the summer, which increases the chance of overuse or overheating. Without proper maintenance, this can lead to a total breakdown. Joe Comer shared: “They were professional and responsive—exactly what I needed to make sure everything was working before it became a problem.”

3. Refrigerant Leaks Low refrigerant levels can severely reduce cooling performance and efficiency. If not addressed quickly, it can cause strain on the system and lead to more expensive repairs. Our technicians, like Brett, are known for identifying these issues early and getting them resolved before they escalate.

Preventative Measures

Regular Maintenance Routine maintenance is the key to avoiding most HVAC issues. Our technician Dustin is frequently praised for being thorough, knowledgeable, and great at walking homeowners through their options. Preventative tune-ups ensure your system stays efficient all summer long.

Smart Use & Settings Don’t overwork your unit. Using programmable thermostats and setting your temperature moderately helps reduce strain. Our team can guide you through energy-saving tips that make a big impact on both your comfort and utility bills.

Proper Ventilation Clean vents and filters matter more than you think. When airflow is blocked, your system has to work harder—leading to overheating and early wear. Regular filter changes and inspections will keep your air flowing freely and your system operating smoothly.

Timely Repairs If something feels off, don’t wait. We pride ourselves on fast, honest service. Richard M. appreciated that our team explained things clearly without overwhelming jargon: “The technician was very professional, respectful, and knowledgeable. He explained everything in layman’s terms.”
