What you need to know about HVAC Systems and the Rain

 

It is time to assess the impact of rainy weather on your heating system and air conditioner. Your outdoor HVAC unit can withstand all kinds of weather, including snow and rain. You may need to wait until a professional is available to service your unit during inclement weather.

 

Design for Weather and HVAC

Your air conditioner will use heat pump technology to transfer heat outside to your home. You can have either a traditional air conditioner or a heatpump capable of heating and cooling depending on the model.

 

One unit, which contains the blower and the evaporator coil, is inside. The other unit (containing both the compressor and condenser), is outside. Split systems are common in many homes in the United States. The outside component is designed to withstand years' exposure to extreme weather conditions. It is made of durable, corrosion-resistant materials such as copper and aluminum.

 

Even with all the precautions taken, your HVAC system may still be damaged from falling tree limbs or wind-driven debris. It is best to do regular maintenance. This includes thorough cleaning.

 

Are Your Outdoor HVAC Units at Risk in the Rain?

Even torrential rain won't have any effect on your outdoor HVAC system. Your heater and air conditioner are safe to use even if it is raining or storming outdoors. Your outdoor unit's only vulnerability to environmental damage is flooding. If it is submerged, its electronics, wiring, and motor could be damaged. The heat pump can be used in rain or standing water, but will not work in the rain.

 

If the outdoor unit has become completely or partially submerged in water, you should turn off the HVAC at the electrical panel. Make sure to inspect the system before turning it on again.

 

Does it make sense to cover the outdoor unit?

No matter the type of your HVAC unit, covering it is not recommended. Its internal condenser was designed to withstand temperature and humidity fluctuations for years. The unit relies on natural ventilation to let moisture evaporate. This allows moisture to dissipate and prevents corrosion and other damages to the internal components. While it is tempting to cover your units with snow, leaves, or other debris in winter, this can actually cause more harm than good. Equipment can be quickly damaged by condensation.

 

You should also keep your HVAC unit off the ground. For the HVAC unit to work properly, there must be adequate airflow. If there are concerns about debris falling onto your unit because of its location, you may be able to build an awning over it. But please consult with a skilled HVAC expert first.

 

Is it possible to have HVAC technicians service units in the drizzle?

It is rare for technicians to service exterior devices while it rains. In addition to the obvious dangers that come with working on electrical parts in the rain, opening doors to allow water to penetrate normally closed areas of the device can cause even more damage. Rooftop units pose a greater risk because of the increased chance of falling or slipping as well as lightning strikes.

 

Although we may send HVAC technicians to your house in an emergency, please be aware that it may not always be possible to do so.
