Tampa Bay Hits 90°F in April: Is Your AC Ready for an Early Summer?

Record-breaking heat swept through Tampa Bay this April, with Tampa International Airport reaching 96°F, surpassing the previous monthly record of 93°F set in 1991. St. Pete-Clearwater International Airport hit 95°F, and Albert Whitted Airport recorded 91°F. For homeowners and business owners across Hillsborough and Pasco County, the unusual spike is raising an urgent question: is your air conditioning system prepared for what’s shaping up to be an early and intense cooling season?

What’s Behind the Heat

Dry conditions and southeast winds pulled unmodified warm air from inland areas, driving temperatures well above the typical April average high of 83°F. Historically, Tampa Bay averages only one day at or above 90°F during the entire month of April, with daily records dating back to 1890. Temperatures are expected to ease into the upper 80s and lower 90s in the coming days, with possible rain offering some relief. But, the region’s humid subtropical climate means the hot and wet season, typically May through October, is right around the corner.

Why This Matters for Your HVAC System

An early heat surge puts sudden demand on cooling equipment that may have been idle for months. HVAC systems that haven’t been serviced since last summer can struggle with efficiency, increased energy costs, and unexpected breakdowns, especially during sustained high temperatures. For commercial properties, system failures can disrupt operations and affect indoor air quality for employees and customers.

Tips to Get Your AC Ready Now

Property owners in Hillsborough and Pasco County can take several steps to prepare their systems before peak summer demand hits:

Schedule a professional maintenance tune-up. A licensed HVAC technician can inspect refrigerant levels, electrical connections, and overall system performance before daily highs climb further.
Replace or clean air filters. Dirty filters restrict airflow and force the system to work harder, increasing energy bills and wear on components.
Clear debris around outdoor units. Remove leaves, dirt, and vegetation from around the condenser to ensure proper airflow.
Check your thermostat settings. Verify that programmable or smart thermostats are set to a seasonal cooling schedule to avoid unnecessary runtime.
Inspect ductwork for leaks. Leaky ducts can waste up to 30% of cooled air, according to the U.S. Department of Energy.
Test the system before you need it. Run your AC for 15–20 minutes to confirm it’s cooling properly and listen for unusual sounds.
Consider upgrading aging equipment. Systems over 10–15 years old may not handle extreme heat efficiently. A newer, high-efficiency unit can reduce energy costs and improve reliability.

Act Before Peak Season

With Tampa’s all-time record high of 100°F set just last July, early preparation is key. HVAC companies across Hillsborough and Pasco County typically see a sharp increase in service calls once sustained summer heat arrives, which can mean longer wait times for repairs and installations. Homeowners and business owners are encouraged to contact Custom Air Conditioning & Air Quality now to schedule preventive maintenance or discuss system upgrades before the busiest months begin.
