What Summer Does To Your Furnace

It’s summer time. Your air conditioning system has been a workhorse all summer long. So why should you be thinking about your furnace with the temperatures still hovering between hot and hotter?

During normal operation, your air conditioner produces water from condensation as it moves across the evaporator coil. This water gets channeled to the drain line and then flows to the drain.What Summer Does To Your Furnace

If your system is working properly, you should never see water on or around your indoor unit. The only sign should be a periodic dripping noise. If you’re proactive in maintaining your HVAC system, most of the risks associated with your air conditioner have been stopped even before they begin. But if you haven’t, you may see signs of a problem lurking around your furnace system too.

As your cooling system ages, dust and dirt accumulate on the evaporator coil. This builds over time and eventually plugs up the drain line. As it clogs, water has nowhere to go, so the water pushes back into the coil and eventually spills onto the floor.

It can also impact your filter. If your filter is clogged, the airflow over the coil will be reduced. This will most likely cause the coil to freeze, allowing excess water to build up and spill over time.

The more water sits where it isn’t supposed to, the more damage it can cause overall. If water rests too long in the drain pan below the coil, rust and holes can occur allowing the water to spill onto the floor.

It’s not your furnace that’s the problem. It’s the impact of an air conditioning system that needs a little TLC.

The key to success in all cases where water is involved is quick action. Sitting water has the potential to damage all it touches. So the quicker you act, the better the outcome.

Look for a shutoff switch near the furnace and coil. If you can’t find it, shut the system off at the breaker. Clean up the water. Then check the filter to ensure it’s clean and unblocked, replacing as necessary. From here, you can use a water-safe vacuum and remove any debris that might be impacting the drain line. If you can’t find the problem, now is the time to call an HVAC professional to assess the damage and fix the problem.
