AC Repair Services We Handle in Lake Mary

Our technicians are trained and equipped to work with all major AC components. Common service calls include:

• Capacitor replacement — the most frequent repair in Florida. Capacitors are destroyed sooner here than in any other part of the country due to the extreme heat load.
• Refrigerant recharge — low refrigerant causes weak cooling. We locate and fix the leak before recharging to the correct level.
• Condensate drain cleaning — humid Florida air creates more condensation. When drains back up, air handlers suffer water damage and mold grows.
• Frozen evaporator coil repair — coils freeze due to low refrigerant or restricted airflow. We diagnose the cause, not just the symptom.
• Fan motor replacement — indoor and outdoor fan motors are constantly exposed to heat and humidity. Our trucks carry the most commonly needed motors.
• Compressor repair or replacement — the heart of the system. We determine whether repair or replacement is the better economic option based on age and condition.
• Thermostat calibration or replacement — short cycling, ghost readings, and temperature swings are often caused by a faulty thermostat.
• Electrical repairs — burned contactors and loose connections create a fire hazard. We check the full electrical panel on every visit.
• Ductwork sealing and repair — leaky attic ductwork can cause 20 to 30% cooling loss. We test, seal, and re-insulate as needed.

Why Lake Mary’s Climate Wears Out AC Systems Faster

Lake Mary sits in Seminole County at the heart of Central Florida, where humidity regularly exceeds 85% and summer temperatures stay above 90°F from May through September. This combination stresses residential AC systems in ways that homeowners and even technicians from cooler climates do not always anticipate.

High Humidity and Condensate Drain Clogs

Your AC removes moisture from the air inside your home and drains it through the condensate line. In Lake Mary, your system may drain several gallons of condensation per day in summer. When warm, damp conditions exist inside the drain lines, algae and mold proliferate quickly, clogging the drain and causing water backup into the air handler, overflowing drain pans, and ceiling or wall damage. Annual drain cleaning here is a necessity, not an option.

Thermal Cycling and Capacitor Failure

Electrical capacitors hold a charge to start the compressor and fan motors. Every time the system cycles on and off, the capacitor goes through a stress cycle. AC systems in Lake Mary run heavily from May through October, far more than systems in cooler climates. As a result, capacitors that last 10 to 15 years in the Midwest often fail in Central Florida after 5 to 7 years. If your system is struggling to start or short-cycling, the capacitor is the first thing we check.

Humidity and Corrosion

Florida’s high humidity corrodes electrical contacts, coil fins, and copper refrigerant lines over time. This corrosion reduces efficiency and causes refrigerant leaks. Our technicians check for corrosion on every service call before it becomes a major failure.

Signs Your Lake Mary AC Needs Repair Now

Do not wait for a total breakdown in July. If you notice any of these warning signs, your system needs attention:

• Warm air from vents — usually indicates a refrigerant problem, a frozen coil, or a failing compressor.
• Poor airflow throughout the house — may be caused by dirty coils, a broken blower motor, or leaking ducts.
• Short cycling — frequent on-and-off cycling wears out the compressor and is often caused by a faulty capacitor or refrigerant issue.
• Unusual sounds — banging, grinding, or squealing indicate loose parts, worn bearings, or debris in the unit.
• Water leaks around the air handler — a clogged condensate drain, broken drain pan, or thawing frozen coil can cause serious water damage if left untreated.
• Unusually high electric bill — dirty coils, low refrigerant, or failing components can cause your system to consume significantly more power.
• Musty or burning odors — musty smells indicate mold in the drain pan or ductwork; burning smells indicate an electrical problem that needs immediate attention.

Repair or Replace? An Honest Answer

Many Lake Mary homeowners contact us asking whether to repair or replace their system. Here is our honest guidance.

The 5/10 Rule

If a repair costs more than 50% of the price of a new system, replacement is almost always the better financial decision. A new system comes with a manufacturer warranty, runs more efficiently, and provides many more years of reliable service.

Age and SEER Rating

In Florida’s climate, systems that are 10 to 12 years or older are approaching the end of their useful life. If your unit is rated below 14 SEER, a modern high-efficiency replacement can reduce your cooling costs by 20 to 40% per year and pay for itself within a few years. See our AC replacement in Lake Mary page for a full breakdown of options and costs.

When Repair Makes Sense

If your system is under eight years old, has a relatively high efficiency rating, and the repair is straightforward (capacitor, contactor, or drain cleaning), repair is almost always the right call. We will give you an honest recommendation either way and never push you toward the more expensive option.

Frequently Asked Questions About AC Repair in Lake Mary

How much does AC repair cost in Lake Mary?

Residential AC repairs in Lake Mary typically range from $150 to $900 depending on the type of repair and labor required. Simple repairs like capacitor replacement or drain cleaning are on the lower end. Compressor issues are more expensive and may lead to a replacement conversation. We always provide a written quote before beginning any work.

How fast can you get to Lake Mary?

During peak summer months, we prioritize repair calls to minimize wait times. Same-day service is our standard. Call (407) 710-7168 for current availability.

Do you offer same-day AC repair in Lake Mary?

Yes. Same-day service is not a premium add-on at Air & Aero — it is our standard. We stock the most common parts on our service trucks so most repairs are completed on the first visit.

Is it worth repairing an older AC in Florida’s heat?

It depends on the age, condition, and repair cost. If repair costs exceed 50% of the replacement value, or if the unit is 10 to 12 years or older with a history of frequent issues, replacement is usually the better investment. Our technicians give you an honest assessment and never push you toward the more expensive option.

What is the most common AC repair in Central Florida?

Capacitor replacement is by far the most common AC repair in Lake Mary and throughout Central Florida. Florida’s extreme heat causes capacitors to degrade faster than in cooler climates. A failing capacitor is often the reason a system will not start or is struggling to cool. The good news: it is also one of the fastest and most affordable repairs we make.
