Frequently Asked
questions.
Honest, straightforward answers about HVAC repairs, replacements, pricing, and system maintenance.
Diagnostics & Service
- What does the $99 diagnostic fee cover?
- The diagnostic fee covers the trip of a NATE-certified technician to your property, a full electrical systems check, temperature differential tests, and locating the source of any mechanical or airflow issue. If you approve the repair, we apply the fee toward the total cost.
- How fast can you arrive for a diagnostic appointment?
- We offer same-day appointments across Duval and St. Johns counties. If your system goes down after hours, we have dedicated on-call technicians ready for emergency dispatch.
- What should I do to prepare my home before the technician arrives?
- To ensure a smooth diagnostic visit, please clear a 3-foot clearance path around your indoor air handler unit (usually in a closet, garage, or attic) and your outdoor condenser unit. Ensure all pets are secured in another room, and make sure someone over 18 is present to approve any diagnostics and upfront pricing.
- How do I know if my AC issue is an emergency?
- If you lose cooling during a Florida summer heatwave (when indoor temps rise past 80°F), or if you smell gas/smoke coming from your HVAC closet, it is an emergency. Other issues like slow temperature drops or minor rattling are standard repairs that can be scheduled for normal business hours.
- Do you charge extra for after-hours, weekend, or holiday dispatches?
- We maintain our flat $99 diagnostic trip fee standard for all scheduled appointments. For emergency dispatch calls handled late at night or on major holidays, our dispatcher will clarify any emergency rates upfront before sending a truck.
- Can you diagnose my system over the phone or send a ballpark estimate?
- To ensure safety and accuracy, NATE standards require an in-person physical inspection of your system's pressure, current, and airflows. An over-the-phone guess can lead to misdiagnosed parts, which is why we offer our comprehensive $99 trip visit to pinpoint the exact issue.
Repairs & Components
- What is an AC capacitor and why do they fail frequently?
- A capacitor is a small electrical cylinder that stores energy to kickstart your AC compressor and fan motors. In Northeast Florida, summer heat causes capacitors to run hot constantly, leading to failure. Replacing them is a standard, flat-rate mechanical repair.
- Why is my AC unit freezing up or showing ice?
- System freeze-up is caused by either restricted airflow (typically a severely clogged return air filter or dirty evaporator coils) or a low refrigerant level due to a system leak. Turn off the system immediately and switch the fan to 'On' to melt the ice before our technician arrives.
- How do I know if my AC blower motor or fan motor is starting to fail?
- Common symptoms of a failing fan motor include screeching or squealing noises (worn bearings), a humming sound from the motor body without the fan blades spinning, or intermittent operation where the fan shuts off due to thermal overload. Continuing to run a system with a failing fan motor can cause compressor damage, so we recommend shutting off the unit and scheduling diagnostics.
- What is a TXV valve and why is it important for my cooling?
- The Thermostatic Expansion Valve (TXV) regulates the flow of liquid refrigerant into your evaporator coil. If the valve gets stuck open or closed, the coil can freeze or run hot, resulting in poor cooling. Replacing it is a complex repair requiring recovery of the system's refrigerant charge.
- How do duct leaks affect my HVAC compressor's health?
- Leaky ducts draw in hot, humid attic air into your return vents, forcing your compressor to work twice as hard to lower the temperature split. This continuous overloading increases thermal stress on compressor bearings and windings, leading to premature burnout.
- Why is my AC system short-cycling (turning on and off every few minutes)?
- Short-cycling is commonly caused by an oversized system, a malfunctioning high-pressure safety switch, a clogged air filter restricting airflow, or low refrigerant levels. If left unchecked, short-cycling damages the starter capacitor and compressor.
HVAC Replacement
- How long does a central air conditioner last in Jacksonville?
- Due to high humidity and near-constant operation, central AC systems in Northeast Florida typically last 10 to 12 years. Properties near the beaches or river may see a shorter lifespan (8 to 10 years) due to salt-air corrosion.
- Should I repair or replace my air conditioner?
- We recommend replacement if your system is older than 10 years, experiences frequent component failures, or if the cost of repair exceeds 50% of the cost of a new system. Modern SEER2 replacement systems also cut monthly cooling bills by 20% to 50%.
- What is SEER2 and how does it affect my new system installation choices?
- SEER2 (Seasonal Energy Efficiency Ratio 2) is the updated federal standard for measuring HVAC efficiency, taking into account actual duct static pressures. In Florida, the minimum efficiency for new central AC installations is 14.3 SEER2. Higher SEER2 ratings (up to 20+) cost more upfront but use significantly less electricity, helping lower your home's utility bills over time.
- What is a heat pump and is it better than a gas furnace in Florida?
- Heat pumps look and run exactly like air conditioners in the summer, but they run in reverse during the winter to extract outdoor heat and pump it inside. Since Florida's winters are mild, heat pumps are incredibly energy efficient and represent the standard heating configuration across Jacksonville.
- What is involved in a professional HVAC changeout?
- A professional installation includes reclaiming old refrigerant, removing the old condenser and air handler, updating the concrete support pad, installing new safety pans and drain float switches, modifying sheet-metal attic plenums, pulling local permits, and configuring digital staging.
- Are there tax credits or rebates available for high-efficiency system installs?
- Yes! Under the federal Energy Efficient Home Improvement Credit (Section 25C), you can claim up to 30% of the cost (up to $2,000) for qualifying high-efficiency heat pump installations. Local utilities also offer promotional rebates for upgrading systems.
Preventative Maintenance
- Why is annual preventative maintenance necessary?
- Routine tune-ups chemically clean dirt and pollen from outdoor coils (lowering system pressure and energy draw), clear algae from drain lines (preventing ceiling water damage), and identify weak electrical parts before they cause a complete summer breakdown. It also satisfies manufacturer parts warranty terms.
- How often should I clean or wash my outdoor unit?
- You should have the coils chemically washed once or twice a year to remove pollen, dust, and grass clippings. Between visits, keeping grass, weeds, and shrubs cut back at least 2 feet from the unit ensures healthy airflow.
- Why is my AC drain line clogging repeatedly, and how does maintenance prevent it?
- Florida's constant heat and humidity combined with dark drain lines create an ideal environment for algae, mold, and biological slime. Over time, this buildup forms a thick clog that backs up water into your home. Regular preventative maintenance flushes these lines with high pressure and applies slow-dissolve chemical tablets to keep the drain flowing cleanly.
- What is a condensate overflow switch and why is it required?
- A float switch sits in your emergency drain pan or primary line. If algae blocks the pipe and water backs up, the float rises and cuts power to your outdoor unit immediately. This prevents water from overflowing and destroying your drywall ceiling or flooring.
- What MERV rating should I choose for my home's air filter?
- For residential systems, filters rated MERV 8 to 11 are ideal, capturing pollen and dust without restricting air volume. Filters rated MERV 13+ are thicker and can create static pressure drops, which strain standard residential blower motors.
- How does salt-air corrosion affect properties near Jacksonville beaches?
- Salt-air moisture accelerates aluminum coil oxidation, causing structural degradation on the fins of outdoor units. This corrosion restricts heat transfer and causes systems to fail in 6 to 8 years. We apply specialized anti-corrosive coatings during maintenance to protect coastal systems.
