How Rain Can Harm an HVAC System

Posted by Wattson on Mar 24, 2022
When the forecast calls for rain, business owners and homeowners worry about the potential damage that could be done to their property. One area that is sometimes overlooked is the HVAC system. Humidity and water can cause a lot of damage to an air conditioner. The good news is, there are ways to protect your HVAC system from moisture and water damage. If you want to avoid water damage altogether, you can consider a ductless mini-split system to replace your current HVAC system.


Water Damage to Your Air Conditioning System

The main concern with rain and your air conditioner is your AC condenser. The condenser sits outside and is exposed to the elements. When water accumulates on the condenser, it can cause damage.


Corrosion to the Metal Parts

The metal parts of your air conditioner are susceptible to corrosion when wet. This can cause the air conditioner to work less efficiently and eventually break down. That’s why it’s important to allow your air conditioning unit to dry out after a storm.


Mold Growth

In addition to damaging the AC unit itself, rain can also lead to mold growth. Mold spores thrive in high humidity environments and will quickly colonize any wet surface if they are there for more than 24 hours. Once mold begins growing, it can be challenging to get rid of and cause many health problems.


Reduced Efficiency

Another problem that can occur is reduced efficiency. When your AC unit is wet, it has to work harder to cool your home or office. This not only wastes energy but also drives up your utility bills.


How to Protect Your Air Conditioner from Rain

Here are a few things you can do to protect your air conditioner from rain damage:

  • Make sure the area around your air conditioner is clear of any obstructions.
  • Ensure yard debris such as branches and leaves are cleaned up to avoid them being blown onto or into your central air system.
  • Make sure the condenser is properly drained to prevent water buildup.
  • Install a gutter or downspout to divert water away from the air conditioner.
  • Invest in a cover for your air conditioner that will keep it dry during rainstorms.


How to Clean Your HVAC System After a Rainstorm

If your air conditioner does get wet, it’s essential to clean it as soon as possible:

  1. Turn off the power to the air conditioner.
  2. Use a garden hose to remove any standing water from the condenser. Once the water has been removed, use a soft brush to remove any debris that may be stuck to the unit.
  3. Turn on the air conditioner and allow it to run until it is completely dry.


Ductless Mini-Split Systems

If you are searching for an alternative to a traditional air conditioning system, consider a ductless mini-split system. A ductless mini-split does not require ductwork, so it can be installed in areas where a traditional AC system would not be feasible. Additionally, since the indoor and outdoor units are separate, the unit can be installed outside without fear of damage from the weather.

Ductless mini-split air conditioners are an excellent option for those who want to avoid the potential damage from rain and humidity. If you are concerned about your air conditioner being damaged by the weather, contact a local HVAC contractor to discuss your options. They can help you find the best way to protect your air conditioner and keep your home or business comfortable all year long.


Parts of a Ductless Mini-Split Air Conditioner

A ductless mini-split consists of two components: an outdoor unit and an indoor unit.


Outdoor Unit

The outdoor unit contains the compressor, condenser, refrigerant tubing, suction tubing, condensate drain, and expansion valve. There is one outdoor unit that connects to the indoor air handlers.


Indoor Air Handling Unit

The indoor contains the evaporator and air handler. The air handler blows air over the evaporator coils to cool them. A fan then circulates the cooled air through the room or space. The indoor units help reduce indoor humidity levels and heat or cool the rooms in your home separately.

The two units are connected by a conduit that houses the power cable, refrigerant lines, and drain line. A small hole is drilled in the wall to accommodate the conduit. Ductless mini-split systems are available in various sizes to meet your cooling needs. They can be used to cool one room or multiple rooms in your home.


Advantages of a Ductless Mini-Split System

There are advantages to choosing a ductless mini-split air conditioner over traditional cooling systems.

  • Ductless mini-splits are more energy-efficient than traditional air conditioners because they don’t lose cool air through ductwork. Their seasonal energy efficiency ratio is higher than conventional central air systems.
  • Ductless mini-splits are quieter than traditional air conditioners, and most models come with a remote control. Then you can adjust the temperature from anywhere in the room.
  • Mini-splits offer individualized temperatures for each room. The indoor air handlers can be mounted on the wall or ceiling and set to your desired temperature.
  • Ductless mini-splits are easier to install than traditional air conditioners since no ductwork is required. They can be installed quickly and easily by a qualified HVAC contractor.
  • Live in a climate where rain and humidity are common problems. A ductless mini-split air conditioner may be the best solution for you as they help control humidity levels and indoor air quality.
