While HVAC systems and window air conditioning units can be a lifesaver in the brutally hot summer months, come wintertime, they are all but useless. But to ensure that your system is ready to run that first warm day of spring after the snow and freezing temperatures, there are a few important questions to ask yourself to protect your system from the elements; the most common, whether or not you should cover your air conditioner.
What is the general rule of thumb?
This is a common question for residents with either central air, but as a general rule regardless of the weather in your area, covering HVAC equipment (central air) located outside of your home is not necessary. Because the units are built to withstand extreme temperatures and weather conditions, there is no need to purchase or make a cover. In fact, part of the huge price you pay for air conditioning systems is for their durability.
Why not to cover your system?
While a covered air conditioning unit won't benefit the system itself, you are going to attract unwanted wildlife. Rodents, snakes, or insects can seek refuge within a covered air conditioner, as it will protect them from the harsh weather outside. This can result in chewed electrical wires that could be costly to replace.
Moisture buildup can also occur inside the cover of air conditioning units because proper ventilation is not possible. Mildew and mold can penetrate the air coils inside and bring harmful vapors into your home or simply block the flow of air entirely.
Is there a time when I should cover the system?
This is a great question, and despite the detriments, there are actually a few times when covering your system could be of great benefit. For example, if you know that you are expecting hail, throw a cushioned cover over the machine to ensure that the potentially strong beating won't dent or damage the exterior of the unit. While hail shouldn't affect the system's integrity, you're better safe than sorry.
Blizzards or heavy snowfalls are the only other time when a cover is highly recommended. Because excess snow could melt and cause water to enter the inner workings of the system, future freezing temperatures will create a "glacier" effect inside of your air conditioner that could damage your coils. Covering the system before a powerful snowstorm could prevent water damage, but make sure to remove the cover once the threat has passed.
For more information, you may want to contact a daikin air conditioning technician in your area, or a technician that is familiar with your specific kind of HVAC system.

Hello. My name is Dean and this is my home and garden blog. Last year, I decided I needed to improve the look of my home. I visited several home and garden centres and various different shops but I just couldn't find the items I wanted. I had this dream of creating a really cool and funky look based on an African design I had seen. My friend suggested that I customise the items to create the look I wanted and began to give me some lessons. I really enjoyed the process and I learnt a lot about how to improve your home and garden.
