Orlando, FL — A prolonged heat wave across Central Florida is placing unprecedented strain on residential and commercial air conditioning systems, with HVAC professionals reporting a sharp increase in service calls as temperatures and humidity remain well above seasonal averages.
Over the past several days, daytime highs in the Orlando area have consistently reached the mid-90s, while humidity levels have pushed “feels like” temperatures even higher. The combination has forced air conditioning systems to run almost continuously, creating ideal conditions for breakdowns, reduced efficiency, and accelerated wear.
AC Systems Running Nonstop
HVAC technicians across Orange County report that many systems are operating without rest during peak afternoon hours. Unlike milder climates, Central Florida’s heat and humidity require AC units to both cool and dehumidify indoor air — a dual workload that intensifies during extended heat events.
“When systems run 12 to 18 hours a day for weeks at a time, even well-maintained units can struggle,” said one local HVAC professional familiar with current service demand. “Older systems are especially vulnerable.”
Common Problems During Extreme Heat
According to industry data and service trends, heat waves in Orlando frequently lead to:
-
Compressor overheating
-
Frozen evaporator coils caused by restricted airflow
-
Electrical component failures
-
Drain line clogs due to excess condensation
-
Thermostats unable to keep up with rising indoor temperatures
Many homeowners report AC units still running but failing to cool homes below the upper 70s — a sign that systems are reaching their operational limits rather than fully failing.
Florida Climate Accelerates Wear
Central Florida’s climate places unique stress on HVAC equipment compared to cooler regions. High humidity forces systems to remove large amounts of moisture, while salt-laden air in coastal areas and frequent storms can contribute to corrosion and electrical issues.
Energy experts note that during heat waves, even properly sized systems may fall behind during the hottest parts of the day. This is often normal behavior, though it can feel alarming to homeowners unfamiliar with how systems perform under extreme load.
What Residents Can Do Now
HVAC professionals recommend several steps during heat waves to reduce system strain:
-
Avoid setting thermostats excessively low
-
Replace or clean air filters regularly
-
Keep blinds and curtains closed during peak sun hours
-
Limit use of heat-producing appliances in the afternoon
-
Ensure outdoor condenser units are clear of debris
Residents are also encouraged to schedule preventative maintenance before peak summer months, as emergency repair wait times tend to increase significantly during widespread heat events.
Outlook for the Rest of Summer
Meteorologists indicate that elevated temperatures are likely to continue throughout the summer, meaning Orlando homeowners may experience ongoing HVAC challenges in the weeks ahead.
As Central Florida adapts to longer and more intense heat periods, HVAC system reliability and energy efficiency are becoming increasingly important factors for both homeowners and property managers.
