Whenever 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.

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.
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.

Repairs That Your Heat Pump May Need
Wednesday, January 21st, 2015Heat pumps have a unique construction and operation that sets them apart from other heating systems. This also happens to make their repair needs unique. Though you should always call a professional HVAC technician to address any issues with your heating system, it pays to know a bit more about how your heating system works. With that in mind, take a look at these repairs that your heat pump may need.
Broken Reversing Valve
The reversing valve is a 4-way junction in the refrigerant line between the indoor and outdoor units of the heat pump. This valve determines which way the refrigerant flows through the system, depending on the position it’s in. This is what makes the heat pump capable of both heating and cooling functions. The valve is comprised of a chamber that contains a slide. This slide has two positions, one for each refrigerant direction. Attached to the slide is an electromagnet called a “solenoid.” When the solenoid is charged, it pulls the slide to one side of the chamber. When the solenoid is not charged, the slide drops to the default position.
A reversing valve can break in two primary ways. The first way is that the slide becomes stuck in the chamber, preventing it from directing the refrigerant flow. The second way is that the solenoid loses its magnetism, rendering it unable to pull the slide from one side of the valve to the other. If the slide is stuck, a technician simply has to open the valve and free it. If the solenoid loses its magnetism, however, it will have to be replaced.
Broken Defrost Cycle
During cold days, the outdoor unit of the heat pump can have ice buildup on the outside of the casing. If the ice manages to cover most or all of the unit, it will cut off the unit’s ability to siphon heat. Normally, the heat pump uses a defrost cycle to melt the ice off of the unit. If you notice that your outdoor unit is mostly or entirely covered in ice, however, that means the defrost cycle isn’t working. You’ll need to call a professional to fix it.
If your heat pump is having issues, call Malek Heating & Cooling to schedule a service appointment. We provide professional heating repair in Evanston, IL.
The Benefits of a Humidifier in Evanston, IL
Wednesday, December 10th, 2014You may have heard once before that too much humidity makes people feel sticky and uncomfortable.
People often complain about the problems associated with having too much moisture in the air, as it can cause an exaggerated feeling of warmth on a hot day. Your body cannot properly evaporate sweat, and you may notice a stuffy, musty feeling in the home or even the gradual development of mold and mildew.
How Low Humidity Can Affect Your Household
Wednesday, December 3rd, 2014Many people are aware that high humidity can be a problem, mostly because of how uncomfortable it can make you feel. Low humidity can be an equal problem, and one of the best ways to reduce the effects of low humidity is with the installation of a humidifier in Evanston, IL. The effects of low humidity may not be as readily seen as those of high humidity, so we’ll describe some issues that can develop from low humidity below. If you opt to install a whole-home humidifier, make sure you hire professionals you can count on. Malek Heating & Cooling has been serving Evanston and the surrounding areas since 1988, so call us today!
Some of the Benefits of Air Duct Cleaning
Wednesday, October 22nd, 2014Winter is on its way, so it’s time to start preparing your HVAC system for the heating season. Scheduling annual maintenance is always important, but what about your ductwork? When was the last time you scheduled professional air duct cleaning in Evanston, IL? It’s recommended that ductwork be professionally cleaned every 3-5 years, so if it’s been longer than that since your last cleaning, call Malek Heating & Cooling and schedule a cleaning appointment with one of our experts.
Reasons to Schedule Duct Cleaning
There are a few reasons to consider scheduling duct cleaning before winter:
- Improved indoor air quality – dirt and dust will build up in your ductwork over time. These contaminants enter the airflow and are delivered directly into your living spaces. This can be particularly problematic for allergy sufferers.
- Increased energy efficiency – a large enough build-up in your ductwork can lead to air flow restriction, which can force your HVAC system to work harder. By removing the build-up with a professional air duct cleaning, you can regain energy efficiency you may have lost.
- Less stress on your system – the air flow in your home circulates, so dirt and dust don’t just stay in your vents, they also coat other parts of your system. Dirty, dusty components can’t work as well as they should, which puts stress on your system. Removing the dirt and dust from your vents can greatly reduce the amount of dirt and dust that enter other parts of your system.
Why Do I Need a Professional?
Duct cleaning involves far more than just vacuuming the registers and the easily-reached parts of your ductwork. With a professional duct cleaning, your entire system is accessed and cleaned, using a variety of specialized tools and professional-grade vacuums. There is also special storage for contaminants collected during the cleaning process.
With a professional duct cleaning, you can improve your energy efficiency, comfort and indoor air quality. Call Malek Heating & Cooling today and schedule an appointment with one of our specialists.
Why Furnaces Are Still Great Ways to Heat a Home
Wednesday, September 24th, 2014Today, there are many different types of heating systems to choose from when you need a heating installation service. Heat pumps provide both heating and cooling to a home while boilers may need fewer repairs over time. Yet with all of these features, one of the most common systems found in homes today is still the furnace.
Gas furnaces pull in the air from your home and burn fuel to heat the air and distribute it through the ducts. With proper care and maintenance, these systems will last for many years and provide efficient, effective heating throughout their lifespans. For the most accurate information about installing furnaces in Evanston, IL, you can contact the technicians over at Malek Heating & Cooling. But as a primer, here are some of the reasons a furnace is still a great choice for many home heating needs.
Why Ice on Your Air Conditioner Means It Needs Repairs
Wednesday, August 13th, 2014If you notice ice on the indoor coil of your air conditioner, it may seem like a minor problem. Of course, air conditioners cool the air, so ice is to be expected from time to time, right? Not quite! Air conditioners do not actually create cool air. Instead, they cool a home by removing heat from the air as refrigerant cycles throughout the system. Ice on the evaporator coil means that something has interfered with the evaporation process and that your air conditioner may not be able to cool your home properly. Scraping the ice off the coil can seriously damage this component, and allowing it to defrost is not enough to address the source of the problem. When you notice freezing, turn off your system immediately and call a professional for air conditioning repair in Evanston, IL. You may have any of the following problems.
