Why Is My AC Struggling During Heatwaves in Colliers Homes?

Quick Answers

During heatwaves, AC systems struggle due to extreme outdoor heat, high humidity, airflow limits, aging equipment, and electrical strain. In Colliers homes, rural layouts, longer duct and electrical runs, open sun exposure, and uneven insulation often push properly sized air conditioners to their limits during prolonged extreme heat.

Why Heatwaves Affect Colliers Homes Differently

Heatwaves don’t just raise outdoor temperatures — they expose how a home’s layout and infrastructure affect cooling.

In Colliers, spacing and construction patterns matter.

Homes are more spread out, often with fewer shade structures and longer distances between the outdoor unit and indoor equipment. AC systems were sized for typical summer conditions, not extended extreme heat. They are intentionally not sized for the hottest day of the year, because oversizing would cause short cycling, poor humidity control, uneven comfort, and higher wear for most of the season.

Some heatwave struggle is a design tradeoff, not a system failure.

The Most Common Reasons AC Systems Struggle During Heatwaves

Extreme Heat Load Beyond System Design

Most residential AC systems are not designed to maintain exact indoor temperatures indefinitely during peak heat.

During heatwaves:

• Outdoor units reject heat less efficiently
• Systems run longer with fewer off cycles
• Cooling recovery slows during late afternoon

In Colliers, open yards and full sun exposure can significantly increase heat gain.

Humidity Increasing System Demand

Heatwaves in the Ohio Valley often include sustained humidity.

This forces AC systems to remove moisture and heat at the same time. That’s why a slightly higher temperature with controlled humidity often feels more comfortable than a lower temperature with moisture left behind.

Oversized systems make humidity control worse by shutting off too quickly.

Airflow Limitations Inside the Home

Airflow issues become more noticeable during heatwaves.

Common Colliers challenges include:

• Longer duct runs due to larger home footprints
• Additions built without airflow recalculation
• Duct systems designed primarily for heating

When airflow drops, cooling capacity drops with it.

Aging Equipment Under Heat Stress

Heatwaves reveal wear that mild weather often hides.

Common stress points include:

• Weak capacitors
• Compressors operating at higher temperatures
• Electrical components nearing thermal limits

This doesn’t always mean failure — it means the system is operating near its capacity.

Electrical Strain During Peak Demand

During extreme heat, regional electrical demand rises sharply.

In Colliers homes, this can cause:

• Voltage drops along longer service runs
• Control boards reacting to unstable power
• Temporary shutdowns for system protection

Even minor electrical instability can reduce cooling performance.

Normal Heatwave Behavior vs. Warning Signs

Normal during heatwaves:

• Longer run times
• Slower temperature recovery
• Steady but reduced cooling

Not normal and needs attention:

• Warm air from vents
• Repeated shutdowns
• Tripping breakers
• Indoor temperatures continuing to rise

Knowing the difference helps homeowners respond appropriately.

A Colliers-Specific Cost Driver Homeowners Overlook

Many Colliers homes have uneven insulation coverage and additions completed over time. During prolonged heatwaves, heat gain varies widely room to room, forcing the AC to run longer without evenly cooling the home.

This often appears to be an equipment issue when it’s actually a home performance issue.

A Common Mistake Colliers Homeowners Make

Lowering the thermostat repeatedly during a heatwave.

This does not cool the home faster. It increases runtime, humidity strain, and electrical stress. Heatwave comfort comes from balance, not lower thermostat settings.

What Better Heatwave Performance Actually Looks Like

Improved comfort does not always require replacement. Often it comes from:

• Airflow balancing
• Duct improvements
• Staged or variable-speed operation
• Reducing heat gain through insulation or shading

There are many steps between “do nothing” and “replace everything.”

How Heatwave AC Problems Are Diagnosed Correctly

Proper diagnosis includes:

• Measuring airflow and temperature drop
• Evaluating humidity removal
• Verifying electrical stability
• Comparing system capacity to actual home heat gain

Heatwave issues should never be diagnosed by symptoms alone.

FAQs About AC Performance During Heatwaves

Is it normal for my AC to run most of the day during a heatwave?

Yes. Longer run times are common during extreme heat.

Why do some rooms cool slower than others?

Long duct runs, airflow imbalance, and insulation differences are more noticeable during heatwaves.

Should I turn my AC off during peak heat?

No. Turning it off makes recovery harder and increases system strain later.
