Welcome to the Comfort Zone Blog Ways to Help Prevent Frozen Air Conditioners Avoid Air Conditioner Meltdown There is nothing better than entering a nice cool house on a hot summer day. And few things are worse than sweltering in the heat as you wait for the HVAC technician to come fix your broken air conditioner, knowing it is going to cost hundreds of dollars to repair. The most common reason for a sudden air conditioner meltdown is frozen pipes and tubes. Why do Air Conditioners Freeze There are lots of things that can cause your AC unit to freeze. A qualified AC professional can help you find the source of the problem, but it does not hurt to understand how freezing occurs so you can take steps to prevent it. Refrigerant Charge: If your AC is running low on refrigerant or the fluid is improperly charged, the system can freeze. Leaks are a common cause of refrigerant problems; these can occur when moving parts rub together or vibrate over time. Leaks are also likely to be found where fittings and shoulder joints are loose.

Only a certified HVAC technician should check refrigerant levels and recharge the system if necessary. Airflow: Restricted airflow can cause the evaporative coils to get so dirty that they drop to a temperature below freezing. Humidity in the surrounding air then collects and freezes around the coils. ac units for small houseIf your air filters have not been changed in more than three months, airflow can be significantly reduced; heating and air conditioning units for one roomundersized ducts are another common cause of poor airflow.ac unit india Outdoor Temperature: Running your air conditioner on cool days can cause the unit to freeze up. Most central AC systems are not designed to work properly when outside temperatures dip below 60ºF.

How to Prevent Freezing Now that you understand the most common causes of air conditioner freezing, you can take positive steps to prevent problems in the future. Refrigerant Charge: To keep fluid levels functional, contact a qualified professional to perform a thorough test on your system. A technician will be able to look for leaks, repair damaged or weakened parts, refill coolant and make sure you AC is in good working condition. It is always a good idea to schedule maintenance before peak season to avoid high prices or emergency service charges. Airflow: Change the air filters regularly, usually about every three months or so. This is the simplest, most cost-effective way to ensure your air conditioner does not freeze. If you notice that the AC’s evaporative coils are already dirty, you will need to have them cleaned by a professional. You may be able to vacuum out some of the debris yourself, but some have coils that need to be removed for proper cleaning. Outdoor Temperature: This one is pretty simple;

just do not use your air conditioner when the outside temperature is below 60º. Not only will you prevent your system from freezing, but you will also save energy and money on utility costs by just opening the windows on cool days.

Statistically speaking, a good portion of the continental US and Canada has its hottest average day of the year right around now. So I thought it was a good time to share some thoughts on the modern household’s biggest energy consumer in July – the Air Conditioner.

See, normally I’d assume that we’re all adults and we’re able to decide for ourselves how to run our own appliances. But after being on my current summer vacation for over three weeks and visiting a large number of family and friends throughout the not-overly-hot Great Lakes region, I’ve noticed that most people leave their goddamned air conditioners running 24 hours a day, whether it is warm or cool outside, with their houses at a stupidly low temperature. Yes folks, it has become obvious that America and Canada both need a lesson from Mr. Money Mustache on how to use their Air Conditioners. I recently measured the power consumption of the central A/C system in my own house. Mine is a “3-ton” (36,000 BTU/hr) system which dates back to about 1998, when my house was built. At the time, it was considered fairly efficient with a seasonal energy efficiency rating (SEER) of 10. Newer units, thanks to EPA rules, are now much better with ratings of 14 and higher – changes the SEER rating translate almost directly into similar percentage decreases in your cooling costs.

When in full operation, my system uses 3,000 Watts (3kW) of electricity, about 500 of which is my furnace blower pumping the cool air around the house (and adding its 500 watts of heat back into the cool air stream, by the way). For those without electrical engineering backgrounds, 3,000 watts is an Absolute Shitload of electricity. It’s enough to run 230 modern light bulbs simultaneously, and it’s equal to having about 15 monster-legged tour-de-France-level cyclists hooked up pumping at race level on bike generators continuously in your basement. At the national average price for electricity of 12 cents/kWh, my air conditioning system burns 36 cents per hour, or $86 per month if used for 8 hours per day. With a three-month cooling season, this would compound to SEVERAL THOUSAND dollars of wasted electricity every ten years. Yet my TOTAL average electric bill in summer, despite an average daily high temperature of almost 90 degrees in Colorado, is really only about $35. How could this be?

The answer of course is that I have just cut out the waste, without sacrificing any real happiness or comfort. Here’s how comfort works. Your body generates heat just by being alive. It needs to maintain its internal temperature at around 98 degrees F, and it depends on the skin surface temperature being lower than this to dump extra heat into the surrounding air. Producing sweat helps you cool the body faster, since the sweat sucks up heat as it evaporates. Humid air cannot evaporate your sweat as quickly, which is why it feels hotter. All basic elementary school science, right? This is why the Southeastern United States is a sucky place to be in summer even at 85 degrees F, while the desert states can feel quite comfy and invigorating at that temperature. Finally, your body becomes more efficient at cooling itself the longer it spends at higher temperatures and humidities. Every summer as I drive from Colorado down into Nebraska and beyond, I break out into a great sweat and need to crank the car A/C.

Even at midnight when the temperature drops into the sixties, I still can’t stand the humidity and need to continue the air conditioning. But within two days, I am comfortable with the higher humidity and I enjoy a regular Eastern summer with no difficulty. As July progresses and things get hotter, I am usually visiting a portion of my family with no A/C, so my body continues to adapt. There are a few days when the temperature is so high that I get uncomfortable, but then I spray myself with the garden hose and drink a gallon of water with ice cubes and all is well. I also take advantage of the natural cycle of the environment. In the US Northeast and Canada, and even more in the Western desert areas, the temperature usually drops at night. So non-A/C users take advantage of this fact to open all their windows, and use large fans (100 watts) to exhaust heat and draw in cool air to chill the entire interior contents of their homes. A 100 watt fan blowing outwards from your highest window is pulling in night air from all other windows that is 10+ degrees cooler than your house.

By sucking in thousands of cubic feet of cool air per minute, this fan is doing almost as much cooling as the 3,000 watt air conditioning unit that does the same job during the day time. The Naturally Cool crowd also makes a point of enjoying more outdoor food cooking and clothes drying on hot days, to further reduce indoor heat sources. This is to be contrasted with the behavior of Air Conditioning addicts, who set their thermostats to a silly temperature below 80 and let that baby run, night or day. They might turn it off at night, but forget to open the windows, so they miss out on the free night-time cooling. I remember staying over at one friend’s house in June and heading out for a midnight errand. It was so cool outside that I needed a sweater. Yet his air conditioner was still running, pumping out the remaining heat from the 90-degree sunny day that had just passed. Meanwhile his body was not bothering adapt to summertime heat and humidity, because his house was always refrigerator-like inside.
