Reversing Valve Diagnostics
This is the heart of your heat pump. If your system is blowing cold air in winter, the reversing valve or its electrical solenoid may be stuck. We test the physical valve and the signal to restore your heat immediately.
Auxiliary Heat Strip Repair
When the temperature hits the Nashville floor, your "emergency" electric heat strips kick in. We repair burnt out sequencers and broken coils to ensure your backup heat is ready when you need it most.
Refrigerant Charge and TXV Service
Heat pumps require a precise refrigerant charge to transfer heat from the cold outdoor air. We calibrate your Thermal Expansion Valve (TXV) to ensure maximum heat absorption even when temperatures drop.

Solving the Nashville “Flash Freeze”
Thawing a Frozen Outdoor Unit
Nashville’s damp, 40 degree rain leads to flash freezing on outdoor coils. We test your defrost control boards and sensor resistance to ensure the unit automatically sheds ice before it suffocates. This precision diagnostic prevents the ice block failures that lead to total compressor death.
Stopping the High-Cost "Toaster Effect"
If your electric bill has doubled and you smell burning dust, your heat pump is failing its primary refrigeration cycle. We audit your auxiliary heat sequencers and amp draws to ensure you are not burning money on emergency resistance strips. This restores technical efficiency and drops your utility costs.
No More Cold Vents in January
If your unit is blowing cold air, your reversing valve is likely stuck in cooling mode. We use manifold pressure tests and electrical signal checks on the solenoid to find the exact point of failure. We restore your heat by addressing the valve logic rather than just guessing at parts.
Maximizing Heat Pump Efficiency in Nashville Freezes
According to TVA field data, improperly calibrated heat pumps can lose 45% capacity during Tennessee freezes. We get it right to prevent expensive backup strips from running.

Why Electric Heat Diagnostic Expertise Matters
Hiller’s Heat Pump Repair Specialists vs. The Other Guys
Heat pumps are digital machines that require refrigeration science rather than just a pipe wrench.
We verify circuit logic rather than guessing.FAQ: Nashville Heat Pump Repair
If your heat pump looks like it is smoking in the winter, it is likely steam. When your unit enters the defrost cycle to melt ice off the outdoor coils, it releases steam. This is a sign of a healthy system.
You should only use the Emergency Heat setting on your thermostat during a total mechanical failure. This setting uses expensive electric strips. If you have to use it, call Hiller immediately for a repair.
A light coating of frost on your heat pump is normal. However, if your unit is encased in a solid block of ice, your defrost board has failed. This requires a professional repair.
If your heat pump is over 12 years old and the compressor has failed, it may be more cost-effective to explore Nashville Heat Pump Installation & Rebates than to continue repairing an aged system.
