Preparing for the Winter? Try These Helpful Heating Tips

Getting your heating system ready for the winter is a big task. But with the right tips, you can do it easily. Last winter was the worst time of the year for my family. Our heating system broke down and left the home freezing cold. We actually created our problem because we didn't check our furnace for issues in the fall. By the time the temperatures dropped a few months later, it was too late to repair the furnace. Instead, we had to replace it. My blog helps you avoid this problem. I offer tips on how to prepare your heating system for the upcoming winter, as well as maintenance tips you can use if it breaks down. Thanks for stopping by.

How To Stop Your AC From Freezing Up

While you may need to eventually talk with an HVAC professional, like Pristine Air Conditioning Corp, about serving older systems, there are a few air conditioning repair tasks that you can perform yourself--including thawing out ice that might accumulate on your air conditioner. You may be surprised to discover that your air conditioner coils are covered with ice on a hot summer day. If you do not correct the underlying problem, your AC will operate less efficiently and will be more likely to fail.

Remove the Ice

To remove the ice, simply shut your air conditioner off. Then, the ice will thaw naturally. To speed up the process, run the fan. Afterward, you will need to determine what is causing the ice to accumulate on your air conditioner in the first place.

Check the Filters

First, check your filter to make sure it is not dirty. Either clean or replace the filter, depending on the type. Clogged filters cause insufficient air flow. Rather than chilling the air, the AC will then chill trapped moisture and turn it into ice. Therefore, cleaning the filter will correct this problem.

Clean the Evaporator Coils

The evaporator coils accumulate dust over time and will need to be cleaned. Rather than cooling, the coils simply build up ice. To correct this problem, you will need to clean the evaporator coils off.

Inspect Your Ductwork

If there is a restriction in your ductwork, this will cause a lack of airflow that will contribute to the ice buildup. Inspect the ductwork and look for any sign of leaks or disconnected sections. If you discover any openings in the ductwork that do not belong, you will need to contact a repair technician. Check all of your air registers to determine if there is any dirt or dust that has accumulated inside. You might need to have your ductwork cleaned out by professionals.

Stop Using Your Unit Below 60

Make sure that you do not continue to use your air conditioning unit if temperatures fall below 60 degrees. AC units are usually not designed to operate well under these temperatures. This often occurs when daytime temperatures are warm, but nighttime temperatures fall below the minimum recommended temperature.

Do not procrastinate with your AC freeze-up. This problem can cause damage and increase the chances that your AC will fail. If you do not know why your AC unit is freezing-up, contact an AC repair technician for help.
