How are Plumbing and HVAC Connected?

February 25, 2021

Did you know that the HVAC and plumbing systems in your home are connected? A problem in one of them can affect both systems. Read on to learn more about the connection between these two primary systems of your home.

The Condensate Drain Line

Many HVAC systems rely on a condensate drain line to direct the condensation produced during the home-cooling process to your home's exterior. In modern houses, the drain line is usually connected to the main sewer line, which is part of the plumbing system.

If the sewer line develops a problem, the condensation will back up in your HVAC unit and eventually overflow. That could lead to rusting of HVAC components, mold growth, and extensive water damage to walls, flooring, and interior ceilings.

Additional HVAC and Plumbing Issues

Your condensate line is routed through ceilings and walls, just like the water-supply pipes that make up your home's plumbing system. As a result, the line is prone to the same failures as your plumbing pipes, such as cracking, rupturing, and broken joints.

Condensation lines don't exude as much pressure as water-supply lines. Therefore, moisture slowly exits the lines at the rupture point. This could damage your walls, flooring, and ceilings. Periodic inspection, cleaning, and flushing go a long way toward maintaining your HVAC condensation drain lines.

An HVAC professional can address issues with your condensate line. However, it's worth mentioning that condensate lines are usually constructed with polyvinyl chloride (PVC) tubing. The best person to fix PVC pipes is a professional plumber.
