Q&A

My Jacksonville home's heat pump isn't switching between heating and cooling. Could it be the reversing valve, and can you repair it?

Yes, a faulty reversing valve is a common reason a heat pump gets stuck in one mode, especially in our climate where the system cycles frequently. Our technicians are experts at diagnosing and repairing reversing valve issues. We'll accurately test the valve and electrical components. If a repair is possible, we'll fix it promptly to restore your system's full function. If replacement is needed, we'll explain your options to ensure efficient, reliable heating and cooling for your home.

I suspect a refrigerant leak in my AC. Do you handle repairs, or will the whole system need to be replaced?

We handle both! For a refrigerant leak, our first step is a thorough inspection to locate the source. Many leaks, especially in accessible joints or coils, can be safely repaired, recharged, and tested. We'll always recommend the most cost-effective solution. However, if the leak is in a major component like the compressor or if your system is older and uses R-22 refrigerant (which is no longer manufactured), a replacement might be the wiser long-term investment for efficiency and reliability. We'll provide a clear, honest assessment so you can make the best decision for your Jacksonville home.

How can regular HVAC maintenance from a local company like Langston's prevent common Jacksonville issues?

Our local maintenance service is specifically designed to catch the small problems before they become big, expensive ones. During a tune-up, we clean and inspect critical components like the heat pump's reversing valve, check refrigerant levels and pressure for early signs of leaks, and ensure all electrical connections are secure. This proactive care improves efficiency, extends your system's lifespan, and reduces the likelihood of a sudden breakdown during a Jacksonville heatwave or cold snap. Think of it as essential, preventative care for your home's comfort system.
