I always took my home's heating and cooling system for granted. That is until I found myself battling one of the hottest days in years and my air conditioner simply refused to turn on. After contacting my local HVAC contractor, I learned that my cooling coils had frozen over from a lack of maintenance. He did get my AC back up and running that day, but he also helped me to look at my heating and cooling system in a whole new light. I have spent a lot of time over the last few years learning more about how to properly maintain my HVAC system and ultimately lower my energy costs. Today, I would like to share this knowledge with you so that I can help you to avoid some of the costly mistakes I have made in the past.
Minisplit heat pumps cool air in a very different way from central air conditioners. It is a continuous cycle of removing hot air, sending it over refrigerant tubes, and then sending the cooled air back. A minisplit heat pump also heats, trading the cooling cycle for heat. It is also much smaller than most units located outside. Problems arise when you use this type of heating and cooling system and it gets buried in a ton of snow and ice. Here is what you should know about air conditioning repair on these units:
First, Clear ALL the Snow Away
The HVAC technician cannot help you if your unit is buried under three or more feet of snow. You should clear the snow away such that you have at least three feet of clearance all the way around the unit. Not only is this vital for repairs, but also to assist the unit in doing what it is supposed to; trade air with the outside.
Use a Heat Source to Melt Ice
Because you are not using the air conditioning part of your heat pump/exchange system right now, the warmer air undoubtedly melted some of the first bits of snow. This creates an ice shield around the unit, which will make it impossible to function. That actually may be why your unit is not producing enough warmth and you are freezing half to death inside the house! Use some sort of heating appliance, such as a hairdryer, to melt the ice shield. Then the technician can open up the unit and take a look at everything inside without having to shatter and chip away the ice first.
After the Repairs Are Made
After the repairs are made, you will need to keep the entire area around your minisplit heat pump free and clear of snow and ice. Consider building a shelter around it, with a covering over the top, that will protect it against the next snowfall. Make sure that the shelter clears the unit by six or more inches all the way around.
That will allow your heat pump to "breathe" while it works, and will not melt or ignite the shelter in the process. The shelter should also be waterproof so that new patches of ice cannot form and encase the unit. If your HVAC technician has any other valuable tips and information, be sure to listen to him/her carefully.
