L & L HVAC Services - Terrell's Expert HVAC Services

This is often a sign of a faulty reversing valve, a common local issue we see. This valve is what allows your heat pump to switch modes. If it's stuck or failing, your system can't change functions. L & L's technicians are experts at diagnosing and replacing reversing valves to restore your system's full capability for our variable Texas weather.

Absolutely. When we install or replace your system in Terrell, we ensure it's the right size and type for our local climate and your home's specific needs. An undersized or outdated unit struggles under extreme heat, leading to failure. A properly installed, modern system from L & L runs more efficiently and reliably, giving you peace of mind when temperatures soar.

Our Terrell-focused maintenance includes checking refrigerant levels, cleaning coils, inspecting electrical components, and ensuring the condenser unit is clear of debris. These steps are critical to prevent the strain that causes mid-summer failures. Regular L & L maintenance helps your system handle the heat efficiently, lowers energy bills, and catches small issues—like a weakening reversing valve—before they cause a complete breakdown.
