A-1 Star Air Conditioning & Heating | Licensed HVAC Repair in Irmo, SC

Our thorough maintenance service includes inspecting your ductwork for leaks that are common in our area, which can waste significant energy. We also check and test critical components like your heat pump's reversing valve to ensure it's switching between heating and cooling modes correctly. Catching these issues early during a tune-up can prevent costly breakdowns and keep your system running efficiently year-round.

Yes, a failure to switch modes is a classic sign of a faulty reversing valve, a common repair we handle for Irmo homeowners. Our technicians are experts in heat pump systems and can quickly diagnose if the issue is with the valve itself, its solenoid, or the electrical control. We'll provide a clear explanation and a reliable repair to restore your home's comfort, whether it's a simple fix or a valve replacement.

Not necessarily. While severely compromised ductwork can undermine a new system's efficiency, we offer solutions tailored to your situation. We can often seal and repair existing ducts. However, during a consultation, we'll assess if your current HVAC unit is also aging and inefficient. If a replacement is the most cost-effective long-term solution for your comfort and energy bills, we handle the complete installation, ensuring the new system and ductwork work perfectly together.
