What to Do If Your HVAC Unit is Damaged by Flooding

Summertime brings tropical storm season to the Jacksonville area. Dark, heavy clouds are blowing into our sunny skies, and bringing with them bucketloads of rain. All that precipitation can cause flooding, which can do significant damage to your home and appliances.

In the case of flooding, this means your HVAC unit ends up soaked or surrounded in standing water. This can cause severe damage to the electrical portions of your air conditioning system. While most outdoor units can survive up to a foot of standing water, unseen damage can still occur in any flooding situation. It is important to contact a professional, such as Snyder Heating & Air Conditioning, for an immediate inspection.

What to Do If Your HVAC Unit is Damaged by Flooding

Should heavy rains, hail, or any other extreme weather catastrophe leave your HVAC unit awash in standing water, there are some urgent steps you should take to prevent dangerous situations and stave off further damage. Use caution as you do the following:

  • Turn off all switches that provide power to your air conditioning system. If you do not feel you are safe doing this, contact a professional right away for assistance.
  • Allow your HVAC unit to dry out completely. Remove all standing water from the area as best you are able. Should there be debris, remove that as well.
  • Your air conditioning should remain off until a professional can inspect the unit. Even if it does not appear damaged, the electronic components inside the unit may have been compromised. Without an inspection, more damage may occur when the air conditioning is put back into use, or worse, dangerous circumstances may occur.

To Cover or Not to Cover

Knowing that water can cause damage to the inside of your HVAC system, it may be tempting to use a tarp to cover the unit in order to protect it. This can cause more damage than it prevents. Tarps and other coverings restrict airflow, which can create damage and shorten the lifespan of your HVAC unit.

Air flow is an important element in both the function and maintenance of your air conditioning system. Moving air allows any normal moisture within your system to dry out. Without the removal of that moisture, rust can occur, as can electronic damage.

Let the Pros Help

Your air conditioning unit is a large investment both in your home’s value and your family’s comfort. Exercising due caution, as well as wisely keeping up with regular maintenance will extend the life of this investment.

Customer Reviews

This was an exceptional experience! We woke up to our A/C on but not cooling (it was 6am and already 81 in the house). The person who set up our appointment was very nice, able to get us seen same-day, and let us know of some options to help save us money.

-Christy Cormier

The service from Sam and Chris was excellent! They were very knowledgeable and professional. They were able to answer all of my questions and completed all of my electrical issues. I will definitely use them again for future jobs. Thank you!

-Adrienne Beal

From the get go I could tell that the Snyder employees were truly professionals and didn’t push to make sales like other companies I’ve talked to my whole life. They took the time to explain so that I could make a decision. The installers and later the duct cleaners were very respectful during their work here. Thank you.

-Mike Daniels

Snyder Heating and AC is dependable, always on time and techs have always been courteous and knowledgeable. Emanuel was a great addition to the company. He was friendly and knew what he was doing. Thank you for great service.

-Linda Ackley

Snyder came in and did a total overhaul of our duct system. They had a great knowledge of what to do to make our home so comfortable! The technicians were all so professional and took great care of us! We’re so thankful for their expertise. Great and easy communication with the call center. We will definitely use them again!

-Crystal Hill

Snyder provided an amazing experience from start to finish. Most of us dread getting estimates with pressuring salespeople. Erik was a great guy, explained all my options and didn’t try to pressure me to act quickly! Justin followed up with my husband and I to offer further assistance in our decision. Again, no pressure, just helped with our follow up questions.

-Michele Bauer

Very prompt, professional, courteous, and cleaned up after repair. Had water line break in my front yard and no pressure. Very pleased and would highly recommend Snyder for all your plumbing, and AC needs. Thank you for making a rough morning get better with ease and professionalism.

-Chuck Jr.

Snyder was easy to get in contact with and had availability the next day. Clint came out and needed some parts so had to reschedule us for the next day for installation. He did a great job converting our old 3 knob shower to one. Looks great! Professional and courteous. 100% recommend this company, especially Clint.
