Frequently Asked Questions

Why is my Silver Spring heat pump struggling to switch between heating and cooling?

This is a frequent issue we see locally, often caused by a failing reversing valve—a key component that changes refrigerant flow for seasonal modes. Dirt, wear, or electrical issues can cause it to stick. JL and Sons HVAC technicians are experts at diagnosing and repairing reversing valve problems to restore your system's proper function and efficiency.

My HVAC system was just installed but isn't working right. Can you help?

Absolutely. Improper installation is a common problem we correct for Silver Spring homeowners. Issues like incorrect refrigerant charge, poor ductwork connections, or faulty wiring can cause poor performance and high energy bills. We perform a thorough evaluation to identify and fix these installation errors, ensuring your system operates safely and as intended.

What should I look for in a quality HVAC installation for my Silver Spring home?

A proper installation starts with a detailed load calculation for your specific home, not a generic estimate. Look for meticulous duct sealing, correct refrigerant levels, and clear communication about system operation. At JL and Sons HVAC, our process focuses on these critical details to prevent the common post-installation problems we frequently repair in the area, giving you lasting comfort and value.
