Your Central Florida Spring HVAC Maintenance Checklist

In most of the country, spring HVAC maintenance means preparing for summer heat that’s still months away. In Central Florida, it means you’re already running out of time. By late March and early April, daytime highs in Eustis and the surrounding area are regularly climbing into the mid-80s, and by May, air conditioning isn’t a luxury, it’s a necessity.

Getting your system inspected and serviced in early spring gives you the best chance of catching problems before the heavy-use season begins, when HVAC companies are at their busiest and parts lead times can stretch longer.

Here’s a complete maintenance checklist to work through this spring.

What You Can Do Yourself

Replace the air filter. This is the single highest-impact DIY maintenance task. A clogged filter reduces airflow, makes the system work harder, and worsens indoor air quality. For Central Florida homes, replace the filter every 30–60 days during peak season.

Clear the area around the outdoor unit. Remove leaves, branches, and any debris that accumulated over winter. Cut back any vegetation within two feet of the unit to ensure adequate airflow.

Check and clear the condensate drain line. Florida’s humidity means your AC produces a lot of condensate. The drain line can clog with algae, especially in warm months. Locate the PVC drain line (usually near the indoor unit) and pour a cup of diluted bleach or white vinegar through it to clear and prevent clogs. A clogged drain can cause water damage and trigger your system’s safety shutoff.

Test your thermostat. Switch the system to cooling mode and verify it kicks on and responds to temperature changes correctly. If you have an older manual thermostat, consider this spring as the time to upgrade to a smart thermostat. The efficiency gains can pay for the device within a season.

Inspect your vents and registers. Make sure all supply and return vents are open, unobstructed, and clean. Closing vents in unused rooms doesn’t save energy. It actually creates pressure imbalances that reduce efficiency.

Check the insulation on refrigerant lines. The copper lines running from the outdoor unit into your home should be insulated with foam. If you see cracked or missing insulation, it can be replaced affordably at a hardware store.

What a Professional Tune-Up Covers

A professional spring maintenance visit from Corman & Sons includes everything above plus diagnostics and adjustments that require specialized tools and training:

• Refrigerant level check. Low refrigerant means poor cooling and possible compressor damage. Only a licensed technician can check and add refrigerant.
• Coil cleaning. Both the indoor evaporator coil and outdoor condenser coil accumulate dirt that reduces efficiency. Professional cleaning restores performance.
• Electrical component inspection. Contactors, capacitors, and wiring are checked for signs of wear or failure. Capacitor failure is one of the most common causes of no-start breakdowns in summer.
• Blower motor and belt inspection. Proper airflow depends on a functioning blower. Worn belts and failing bearings are caught during inspection before they cause a breakdown.
• System performance test. Temperature differential across the coil, airflow, and operating pressures are measured to verify the system is performing to spec.

When to Schedule

For Central Florida, March is the ideal time: after the mild winter season and before the heat arrives in force. Scheduling a tune-up now means you get a timely appointment, your technician isn’t rushing, and any needed repairs can be completed before you’re depending on the system around the clock.
