Armstrong Plumbing & Heating | Licensed HVAC Services in Union, NJ

During our plumbing inspection, we check all water drainage lines connected to your HVAC system, including the condensate drain from your air handler. A clogged or improperly draining line can cause water to back up and pool around the outdoor condenser's base, accelerating corrosion of the coil and unit housing. By ensuring proper drainage, we help remove a key source of moisture that contributes to this common local problem.

Yes, it's possible. While thermostat issues are often electrical, a less common cause can be related to plumbing. Some high-efficiency furnaces have safety switches that shut down the system—including thermostat power—if a condensate drain line is clogged, mimicking a thermostat failure. Our plumbing inspection includes checking these critical HVAC drainage components to rule out this potential cause and get to the true root of the problem.

Our thorough plumbing inspection for Union homeowners includes several HVAC-specific checks: we examine the condensate drain line for clogs or leaks, verify the drain pan is clear and functioning, ensure the water supply line to your humidifier (if installed) is secure and properly valved, and check for any signs of water damage or condensation near air handlers that could indicate a future problem. This proactive approach helps safeguard your entire home comfort system.
