Malfunctions with an air conditioning system are not always easy to detect (unless you are a trained HVAC professional). A slight drop in the cooling levels in one of the rooms, a hissing sound from the outdoor condenser unit, an uptick in electrical bills when the AC is running, and water condensation around the indoor unit are all small indications that something is wrong with a residential air conditioner. There are larger and more obvious signs, of course, such as loud grinding sounds, constant short-cycling, or a system that won’t turn on at all.

When Is the Best Time to Call for Air Conditioning Repair?
Monday, June 1st, 2015Summer Is Almost Here: Is Your Air Conditioner Ready?
Monday, May 25th, 2015We are less than a month away from the official start of the summer season. Now is the time to take an inventory of your air conditioning system to see if it is prepared to make it through the heavy amount of labor it will need to perform all that through and into the fall. If you air conditioning system isn’t in good working order, you may end up with emergency repair calls and even an irrevocably broken AC. You don’t want that to happen, so here are a few steps to take to see that your air conditioner is ready for the coming season.
Reasons Your Air Conditioning Bills Are So High
Monday, May 18th, 2015Do you think that you’re paying too much to keep your home cool through the hot season? Perhaps you’ve noticed that utility bills have been rising higher during the last year or so, despite no discernable increase in the amount that you use the AC. If this is the case, there are a number of possible reasons for it. In this post, we’ll look at a few of those reasons for rising cooling costs… and what you can do to reverse the trend.
3 Odd Noises from an Air Conditioner: What They May Mean
Monday, May 11th, 2015Whenever any mechanical device starts to make noises that are out of the ordinary, it usually means it’s malfunctioning and needs repairs (or in some cases a replacement). The air conditioning system that cools your home over the summer is no exception. Sounds that you aren’t used to hearing are a wake-up call to contact professionals for repairs. Below are three strange noises you may hear from a faulty AC and what they probably mean.
What Does the Refrigerant in an Air Conditioner Actually Do?
Monday, April 27th, 2015You probably know that one of the basic components that makes an air conditioner work (and most types of refrigeration equipment) is a chemical called refrigerant. But how much do you know about how refrigerant works to keep your home cool during the summer? If you’ve ever been curious about refrigerant, we have some facts to share with you. However, this information is no substitute for professional skill and training, so whenever your air conditioner starts to experience trouble doing its job, make sure to call on HVAC technicians to take care of the necessary AC repairs.
What does refrigerant do in air conditioning maintenance?
- Absorbs indoor heat by evaporating in the indoor coil
- Releases heat outdoors by condensing in the outdoor coil
- Cycles between liquid and gas to transfer thermal energy
- Helps cool your home efficiently without ducts
- Low refrigerant levels can signal a leak and need immediate service
When Should I Schedule Maintenance for My Air Conditioning System?
Monday, April 13th, 2015Summers can grow quite hot in Evanston: try to imagine making it through a week or even a few days in July without an AC that will always come on when its needed—and stay on as long as it’s needed. The best way to have this assurance of reliability and performance is to schedule maintenance for the system from a professional HVAC technician. You’ll receive a thorough check-up and inspection, plus any necessary adjustments, that will see that your air conditioner will remain energy-efficient and with little chance of encountering repair needs through the year.
To arrange for regular maintenance from some of the best AC technicians in Evanston, IL and the Chicagoland area, call up Malek Heating & Cooling today.
Here’s Why Low Refrigerant in an Air Conditioner Is a Serious Problem
Monday, April 6th, 2015The 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, 2015Most 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.

How Strange Noises Alert You to Air Conditioning Repair Needs
Wednesday, August 27th, 2014Although today’s manufacturers make air conditioners with many advanced features, they have yet to design one with a perfect self-diagnosing computer that can immediately identify when they need repair and report it to homeowners. You still need to watch out for clues that your AC has developed a malfunction. Fortunately, many repair problems in an air conditioner will create a distinct and unusual sound, and you can use these noises to figure out that you need to call for professional HVAC technicians.
We’ve put together a list of some of the more common noises that malfunctioning air conditioners can make and what they might mean. You shouldn’t use this information to attempt the repair work on your own, however. Call Malek Heating & Cooling—any time of the day or night—when you require skilled air conditioning repair in Northbrook, IL. We will send a technician to your home to track that strange noise to its source and then handle the repair work.
Some Repair Warning Noises to Listen For
- Hissing: This sound like a high-pressure gas escaping from a nozzle probably means that there is a refrigerant leak somewhere in the AC. Loss of refrigerant charge will lead to an air conditioner that cannot maintain its proper cooling level, and it may eventually cause irreparable damage to the compressor. Repair technicians will locate and seal the leak, then recharge the refrigerant to its regular level.
- Grinding, groaning: These mechanical noises are often indicators that one or more of the motors in the system is wearing down from excess stress. This can happen because of loss of lubrication or dirt accumulating across the moving parts. Technicians can attempt to repair the motor, or in the case of a burnt-out motor, replace it.
- Clicking: If you hear a clicking sound as the AC tries to start, you may have dying capacitors. The capacitors store and send charge to the motors to start them running and keep them running. When capacitors start to fail, the air conditioner will “hard start” and drain excess power. Technicians will replace the bad capacitors or install a hard-start kit to overcome the problem.
- Clanging, striking: This often points toward a damaged fan. Bent fan blades will cause the fan to begin striking its outer casing, and this can lead to the damage spreading. For older air conditioners, this may indicate a snapped fan belt. (Newer ACs use direct motors instead of fan belts.)
Whatever the reason for the strange sounds, don’t let a noisy air conditioner continue to run: the problem will worsen and cause a chain reaction of other malfunctions, and the AC will drain money. Call for repairs right away.
Since 1998, the people at Malek Heating & Cooling have delivered air conditioning repair in Northbrook, IL and the rest of the Chicagoland area with fast and effective service for their ACs. Make us your first call when you hear those strange sounds rattling around inside your cooling system.
