Frequently Asked Questions
My Orlando AC isn't cooling well. Could it be a refrigerant leak, and how do you fix it?
Yes, refrigerant leaks are a common issue in our Florida climate and a leading cause of poor cooling. Our technicians use electronic leak detectors and UV dye to accurately locate even the smallest leaks. We then repair the leak, perform a thorough vacuum and pressure test to ensure it's sealed, and recharge the system with the precise amount of refrigerant specified by the manufacturer. This restores efficiency, protects your compressor, and helps you avoid recurring repair costs.
What are the signs my Orlando heat pump's reversing valve is failing, and what's the repair process?
If your heat pump is stuck in one mode (only heating or only cooling), making a hissing noise, or struggling to reach the set temperature, the reversing valve is likely the culprit. We'll test the valve's solenoid and check refrigerant pressures to confirm. Often, debris from normal wear can cause it to stick. We'll first attempt a repair by flushing the valve line. If it's electrically failed or damaged, we'll replace it with a high-quality OEM part, restoring your system's ability to switch between heating and cooling as needed.
Why is proper refrigerant charge so important for my HVAC system in Orlando?
Florida's heat means your AC or heat pump runs constantly. An incorrect refrigerant charge, whether too low from a leak or too high from improper service, forces the system to work harder. This drastically reduces efficiency, increases your monthly bills, and can lead to a catastrophic compressor failure—the most expensive part to replace. Our precise charging process, based on manufacturer specs and ambient temperature, ensures peak performance, longevity, and lower energy costs for your home.
