Here’s Why Low Refrigerant in an Air Conditioner Is a Serious Problem

Monday, April 6th, 2015

The air conditioning that keeps your home cool during the summers uses a chemical blend called refrigerant to run. This is what allows the AC to carry out the process of heat exchange: the refrigerant absorbs heat from inside your house through evaporation, and then releases the heat to the outside through condensation.

There is something very important you need to know about refrigerant: it isn’t something your air conditioner “uses up.” It doesn’t work like gasoline for a car or natural gas for a furnace. The refrigerant inside the AC won’t dissipate as it goes through heat exchange, and it should remain at the same level (known as its charge) as long as you have your AC. If the charge drops because of a leak, your air conditioner will encounter major problems. At the first sign that your air conditioner is losing cooling power, call for repair technicians.

If you need air conditioning repairs done fast and done right, call on Malek Heating & Cooling for service in Skokie, IL and the surrounding areas. We have 24-hour emergency help available.

There are a number of reasons that low refrigerant is bad news for an AC and needs professional repairs right away:

  • Drop in cooling power: Without the right level of refrigerant, the air conditioner will not be able to absorb the amount of heat from inside your home necessary to reach the cooling level you expect.
  • Ice along the coils: The refrigerant that moves through the evaporator coil will not warm up enough because of its reduced amount; the remaining refrigerant will stay too cold and begin to freeze water moisture along the coils, which will further restrict heat exchange.
  • Damage to the compressor: This is the most serious problem low refrigerant may trigger. The change in pressure in the air conditioner because of loss of charge will place extra stress on the compressor, leading to it rapidly wearing down. The compressor may also overheat because of the lower amount of refrigerant. A burnt-out compressor is the most expensive repair an air conditioner may require, so you must have low refrigerant fixed as soon as possible.

Malek Heating & Cooling has taken care of air conditioning repairs since 1998. Give us a call when you need help with your home cooling. If your AC has lost charge, we will seal up the leaks and recharge the refrigerant to the right level.

3 Air Conditioning Components You Should Know More About

Friday, April 3rd, 2015

Most homeowners know very little about what goes on inside of the air conditioning system. And for the most part, this is okay. Why should you have to worry about the inner workings of your AC when you can call technicians to take care of AC services for you? For the most part, all you have to do is program your thermostat and let the system do the rest. But if you want to prevent problems from occurring with your air conditioning unit—or even prevent damage to your home—you may want to get a little more familiar with some of the key components featured in this guide. And call the friendly technicians at Malek Heating and cooling when you’re ready to schedule air conditioning services in Evanston, IL.

  • Air Filter – You probably know that the air filter helps your family breathe a little easier by filtering out some common contaminants. But you may not know just how much damage a dirty filter can do. When the filter is clogged, air cannot get through, but your unit is designed to let in a certain amount of airflow. Without it, the evaporator coil can freeze over, and many of the components could falter as a result.
  • Thermostat – Now, you probably already know the basics of how to use your home thermostat. But are you taking advantage of all of the features yours has to offer? Make sure to program your thermostat to cool your home at an efficient temperature when you are home, and to raise the temperature (or shut off the system) when you’re away. Try not to frequently adjust your thermostat or set it to a lower setting than is necessary, as this will reflect on your energy bills.
  • Condensate Drain – This is a part you may be less familiar with, but it’s important to know that your air conditioner can leak and cause some major damage to the home, especially if your unit leaks through your ceiling and into your home. Have a technician visit for air conditioning maintenance to prevent this possibility.

Call Malek Heating & Cooling for professional air conditioning service in Evanston, IL. Whether it’s maintenance, repairs, installation, or replacement that you need, our qualified team is here to handle in for you.
