What causes a frozen evaporator coil and what can you do about it?

It’s the hottest day of the year, and your air conditioner just stopped working. You walk outside to inspect the outdoor unit and you’re greeted by a strange sight: ice. As it turns out, you have a frozen evaporator coil. In this article, we’re going to talk more about what causes this phenomenon and what you should do if this happens to your air conditioning unit.

At King Heating, Cooling & Plumbing, we’re here for you and your home’s air conditioning needs with our 24/7 emergency service. Call us today for fast, reliable air conditioning repair.

Preventing a frozen evaporator coil here in Chicago.

Schedule an AC tune-up with King every spring and have one of our technicians look at your refrigerant levels ahead of summer.

What causes an evaporator coil to freeze?

Let’s start by talking about how your air conditioner works in the first place. In the simplest of terms, air conditioners (and heat pumps, in their summer setting) are able to cool down your home by moving heat energy from one place to another. The evaporator coil contains refrigerant that runs inside and outside in a constant, contained loop. As the refrigerant enters the inside portion of its circuit, the molecules expand, cooling down the line and allowing it to absorb heat energy from the air in your home.

It then returns to the outdoors, where the condenser condenses those same molecules, causing the line to heat and expel that heat energy into the outdoor air. This happens over-and-over again until sufficient heat energy is removed from your home to bring it down to the temperature where things are comfortable.

In the event that heat energy is not able to be absorbed into the refrigerant, things start to go wrong. Most often, this occurs because the return air—the heat energy-filled air inside of your home—is unable to get to the line. As a result, the refrigerant in the line begins to get colder with no heat to absorb. The line gets cold enough that the condensation on the outside of the line—which normally drains away harmlessly—freezes over, leading to a literal block of ice.

What are the most-common causes of this problem?

Essentially, anything that blocks airflow to the evaporator coil can lead to a frozen evaporator coil. Here are some of the most likely culprits:

Dirty coil

Over time, your system’s evaporator coil will become covered in dust, dirt, grime, and more. This prevents it from getting the airflow it needs to properly move heat, which means that the system could then freeze over. Evaporator coil cleaning is an essential part of our AC tune-up service for this exact reason.

Blocked air ducts

In the event that you’ve manually shut many of your home’s floor or ceiling registers, the return air flow to the coil may not be getting sufficient airflow to continue operating correctly. Another common cause of this problem is when homeowners unknowingly block floor registers below furniture or rugs. Similarly, an extremely dirty air filter can block a main source of air from reaching the line.

Low refrigerant

The refrigerant line is a closed-loop system. However, in some cases, refrigerant may be lost through leaks or other problems. Without enough refrigerant, the molecules expand too much, causing a runaway cooling effect that results in a frozen-over system.

How should you go about fixing this problem?

First things first, you’re going to want to turn off your air conditioner. At this point, any further operation by the air conditioner is just going to keep refreezing the already-frozen line. Then, call the trusted technicians here at King Heating, Cooling & Plumbing. We offer 24/7 emergency AC repair services throughout Chicagoland. When our tech arrives at your home, they’ll inspect the problem and then likely switch the thermostat to its fan-only setting to accelerate the thaw.

Once the system has fully thawed out, we’ll need to address the original cause of the problem. It’s likely one of the three culprits listed above: dirty coils, blocked air ducts, or low refrigerant. If it the latter, we can recharge the system with the appropriate refrigerant type and address any leaks that caused the system to lose refrigerant in the first place.

Common AC problems and what you can do to prevent a breakdown

No one wants to be stuck on a hot and humid summer night with an air conditioner that isn’t working correctly. One important way to prevent a breakdown is to catch issues as soon as possible. Here are a few common AC problems to keep an eye on.

If your air conditioner is running into trouble, call King for 24/7 emergency AC repair service. We’re ready to help! Plus, we don’t charge you extra for work on evenings or weekends.

You can keep your air conditioner running right throughout the summer by keeping an eye out for these common AC problems.The most common air-conditioning problems

Here are some of the most common AC problems and what they could indicate. Remember: King Heating, Cooling & Plumbing offers 24/7 emergency service here in Chicagoland!

  • The house doesn’t feel cool: You hear the fan running and air is flowing, but it doesn’t feel cool. This problem can have many different causes, from dirty air filters to low coolant levels.
  • The fan isn’t working: When you set the thermostat to “cool” or “fan,” nothing happens. A common cause of this issue is a tripped circuit breaker. If the unit has power, the fan may have a worn belt.
  • The AC doesn’t turn on: If the AC doesn’t turn on at all, there may be a thermostat issue or a power problem. If the compressor doesn’t engage, the start capacitor may be the problem.
  • The AC won’t stop running: Sometimes fan or condenser problems cause the air conditioner to run continuously. This behavior isn’t normal, even if it’s hot outside.
  • There’s a weird smell or sound: Among the most noticeable problems are strange noises coming from the air conditioner, such as grinding, squealing, or popping sounds. Burning smells are also serious signs of trouble. Turn off your system and call the professionals at King.

What you can do to keep your AC in great condition

To prevent a breakdown, it’s essential to act quickly when you notice something odd. This means calling professionals ASAP. Our expert AC repair technicians can find the underlying cause immediately, preventing long-term damage to costly components such as the compressor.

In addition to emergency repairs, it’s a good idea to schedule preventative maintenance that focuses on cleaning and system analysis. Annual inspections can find issues before they become a problem. You can also contribute to a long-lasting air conditioner by replacing your air filter every 2–3 weeks and clearing away any dirt or debris.

Why you should replace your air conditioner filter regularly

Your air filter is an essential part of your summer cooling, and keeping yours clean is a must. If you need your filters cleaned or replaced, call us. King specializes in air conditioning repair in Chicago and the other communities of Chicagoland. In this article, we’ll review just a few of the reasons that clean air filters can be the difference between a struggling cooling system and one that’s running better and saving you money.

Call King for air filter cleaning and replacement, as well as air conditioner repair in Chicago.

An air filter that is completely clogged with dirt and dust can completely obstruct air flow into your home, making your air conditioner work that much harder.

Why does replacing your air filter matter?

#1. Energy-Efficiency

If your summer electric bills are painful, you aren’t alone. Air conditioning systems use a lot of electricity, which is why squeezing the best-possible efficiency and smooth operation out of your system is essential. One of the biggest culprits in decreased efficiency is a dirty, clogged air filter, as this means the air conditioner has to work harder to cool your home, burning through more energy as it does so.

#2. Extend your system’s lifespan

An air conditioning system represents a significant investment, which is why it’s in your best interest to arrange regular AC maintenance appointments. Not only does a clogged filter decrease the unit’s efficiency, but it also puts additional and unnecessary stress on the system. By working harder to keep your home cool, you’re putting extra wear-and-tear on your air conditioner that, cumulatively, could mean that it lives a shorter life and you have to replace it all that much sooner.

Our recommendation? Take care of your air conditioner by having the air filter cleaned or replaced regularly, and make sure you keep up with our tune-up service.

#3. Keep your house clean

Your filter’s job is to collect the dust and debris that accumulates over time, but those impurities have nowhere to go if the filtration system is full. Until you replace your filter, the air conditioner will simply circulate this unwanted material around your home, which means you’ll spend more time dusting than not. It’s better to have dust, dirt, and other contaminants caught up in the filter than entering your lungs.

#4. Protect your family’s health

Along with dirtying your house, all of those harmful particles can also cause health problems for your family. Along with dust and dander, your HVAC system can also circulate any mold particles throughout your home without them getting caught up in the filter. If any member of your household suffers from respiratory ailments or allergies, frequent filter replacement is even more important to their comfort in the home.

Call King for filter replacement and air conditioning repair in Chicago

These are just a few reasons why it’s important to frequently replace your cooling system’s filters. Call the team of experts here at King Heating, Cooling & Plumbing and have us work with you and your home on a complete maintenance and upkeep strategy for your air conditioner. To schedule an appointment for filter replacement or air conditioning repair in Chicago, call us.

Winter is around the corner, and it’s time to schedule a heating tune-up

Chicago’s winters are not for the faint of heart, which is why it’s important to have a strong, properly operating furnace to help you get through the colder months. To make sure your system works when you turn it on, it’s a good idea to schedule a heating tune-up every year, and fall is the perfect time for this.

For professional furnace tune-ups here in Chicagoland, contact the team at King Heating, Cooling & Plumbing.

Here’s why you should schedule a heating tune-up

#1. You can catch small problems early

Your furnace contains a complex network of moving parts that will eventually wear down over time. When we perform an annual fall tune-up on your system, we thoroughly inspect and clean each element. By making note of potential issues, we can prevent one worn part from creating a larger problem. In fact, King offers a 40-point furnace inspection and tune-up.

#2. You can get more out of your heating dollar

No matter if your furnace uses oil, natural gas, propane, or electricity, it can be expensive to keep your home warm during a Chicago winter. To get the most out of your energy expenses, your heating system needs to run at peak energy-efficiency. An annual tune-up can ensure everything is in proper working order efficiency-wise.

Over the course of the entire this winter, this could save you a lot of money on your heating bills.

#3. You can stay in compliance with your warranty

Heating systems come with lengthy warranties that cover key components in the event of breakage, but you have to keep up your end of the deal as an owner. If you don’t adhere to the manufacturer’s recommended maintenance schedule, you might not be protected if the system fails.

#4. Keep your family safe

You probably don’t think of your furnace when everything is running properly, but it’s a device that uses combustible material to heat your home. If you don’t take care of maintenance issues regularly, you could end up with an unsafe situation such as a carbon monoxide leak or even a fire hazard.

Schedule a heating tune-up from King today!

Why set yourself up for a larger issue with your furnace that could be avoided by regular fall HVAC maintenance? You’ve spent a lot on your system, so trust the experts at King Heating, Cooling & Plumbing with all of your service needs. To schedule an appointment, contact us online today.

Why you should make the switch to a new Carrier air conditioner

Earlier this summer, we outlined some of the reasons you should change out your old, failing air conditioner for a newer model. However, here’s something else to consider: you should switch to a new Carrier air conditioner. As one of the world’s most-trusted names in indoor comfort, Carrier is the right system, and King is the right team to install it.

Pictured: A King rep talks to homeowners here in Chicagoland about their new Carrier air conditioner.The best place to start after reading this blog? Give us a call to schedule a free in-home estimate on a new Carrier system. During this estimate, we’ll help you find the right air conditioner for your home and your family’s cooling needs.

Why Carrier?

Carrier is one of the world’s oldest and most-trusted cooling companies. There’s a reason for that, actually: their namesake Willis Carrier practically invented the first air conditioner all the way back in 1902.

Most companies would just ride those credentials all the way to today, but the incredible thing is that Carrier has continued to innovate, invent, and establish themselves as one of the top HVAC manufacturers in the world. Today, they’re at the cutting-edge of sustainability, energy-efficiency, quiet design, and a number of other categories.

What makes a new Carrier air conditioner different?

Carrier’s whole line of air conditioners is built to impress. First, these systems are balanced, providing equal parts energy-efficiency, cooling performance, and quiet design. This results in a happier, cooler home, without the huge energy bills in the summer. Believe us: with the heat and humidity here in Chicagoland, you want to cut right through that and have a comfortable home.

Perhaps these hallmark qualities of a great Carrier air conditioner are best seen in the Infinity® 20 Air Conditioner with Greenspeed® Intelligence. Arguably one of the most efficient air conditioners available today, this system packs a cooling punch. It’s the top-of-the-class.

Why Carrier versus other brands?

Ask your neighbors: chances are that the system they trust to cool their home is a Carrier. That’s because generations of Americans have turned to Carrier for superior comfort and cooling. Carrier has long been focused on saving people money on energy bills while still providing high-quality systems.

Here’s another great reason to choose a Carrier: King’s professional AC installation experts can help you install your new system right. After all, an air conditioner is only as good as the installation, and our NATE-certified techs have the know-how and training to make sure your air conditioner is good to go and ready to start cooling your home.

To get started on your free in-home estimate, contact us! We’d love to meet with you and help you find the right Carrier for your home.

Here are the big signs you need AC repair this summer season

When you come home in the summer, you want your home to be comfortable. When your air conditioning system isn’t working properly, your summer becomes miserable. In this blog, we’ll review the 5 big signs you need AC repair this summer, and when you need to contact King for emergency AC service here in Chicagoland!

5 signs you need AC repair this summer

#1. Your house is hot and uncomfortable

The most obvious warning sign is when your house is warm no matter how much you’re cranking the AC. An AC unit that’s not blowing cold air or isn’t blowing much of anything at all will make your home humid and muggy. There may also be unequal cooling in different rooms.

Pictured: Here are the big signs you need AC repair this summer.#2. Your HVAC system is loud

When you turn the air on, you should hardly hear a thing. You may hear a slight rumble and a faint noise of blowing, but if there’s an exceptional amount of noise, there’s probably an issue. If you hear any grinding, chattering, or squeaking, you need summer AC repair.

#3. There is a leak, or pooled water by your AC unit

Excessive moisture and leaks near your HVAC unit is a sure sign there is an issue with your system. If you see water pooling near your AC unit, there is a possibility that the pipes or drainage tubes are broken or blocked.

Water pools may pose an electrical hazard or cause mold. Leaking refrigerant fluids may be a risk to your health.

#4. You smell unusual odors

Your AC shouldn’t smell like anything. If your AC is causing your house to smell instead of cooling it down, there may be mold building up inside the unit. Don’t simply try to plug your nose, light a candle, or use an air freshener. You need to contact King for emergency, 24/7 repair.

#5. Your monthly energy bills are increasing

The last thing you need is a higher energy bill. If you’re wondering why you’re suddenly paying more to cool your house, it may be because your AC unit is working harder than it should. A sudden spike in your monthly bills is a clear indication you should contact King for AC repairs. You can also avoid higher energy bills throughout the season by scheduling an AC tune-up.

Seeing, hearing, or smelling the signs you need AC repair? Call King!

If you notice any of these signs you need AC repair, it’s crucial for you to get in touch with the HVAC professionals here at King Heating, Cooling & Plumbing. Contact us for the best air conditioning repair and maintenance in Chicagoland!

Save energy this summer by switching your old AC to a new model

This summer season, do yourself and your family a favor by considering switching your old AC to a new model. Make the change from your current, worn-out AC unit to an energy-efficient Carrier system. It’s easy to enjoy the many benefits such a change can offer.

King Heating, Cooling & Plumbing is here to keep you and everyone else in your home as comfortable as possible no matter the time of year. In this blog, we’ll discuss the benefits of upgrading to a new air conditioner this summer.

Boost your home’s energy-efficiency

While installing your new unit, you might find out that there are several reasons your home isn’t as energy efficient or kept as comfortable as you’d like for it to be. For instance, it might be that you need a new unit and that your home’s insulation isn’t as great as it should be.

There might also be energy leaks in your home as well as leaks around your windows and doors that need to be addressed. There’s little need to get a new air conditioner and leave it at that if more work needs to be done to your property.

Invest money rather than waste it

When you spend money on repairs to an older HVAC unit that’s really starting to show its age, what you’re doing is wasting money rather than making a good investment. This is because your money is better spent on a newer unit that will last longer, rather than on a unit that’s likely going to completely fail soon.

Get the right-sized unit for your home

You can also save energy by getting the correctly-sized air conditioner for your property. Units that are either too big or too small drive up energy costs. Also, a unit that’s too large for your home is likely to fail faster than an accurately-sized unit.

This is why it’s vital that you choose a reputable and experienced company (like King!) for switching your old AC to a new model.

If that wasn’t enough, a solid maintenance record—the kind you’ll have as a member of a HVAC maintenance program—has two other benefits. First, you’ll keep your manufacturer’s warranty intact. Second, you’ll extend the lifespan of your system.

As a member of a HVAC maintenance program like the King Royal Treatment Plan, you’ll receive regularly scheduled tune-ups that keep your system running at their best. At our company, we call you to schedule these tune-ups, making the process all that more convenient.

Ask any homeowner: on the hottest days or coldest nights of the year, when the air conditioner or furnace has stopped working, being first in the queue for service from a trusted HVAC company matters. That’s why this particular perk of your HVAC maintenance program makes all the difference.

#3. All the other perks

Companies often throw in a number of other awesome perks with their HVAC maintenance program. Here at King, Royal Treatment Plan members—on top of regularly scheduled tune-ups and priority service—also get a discount on parts and labor.

What NATE-certified means (and why you should choose King)

When you need AC repair this summer, you want to hire the best to work on your system. In this blog, we’ll explain why NATE-certified techs are the best the HVAC industry has to offer, and why King hires experienced professionals to work in your home.

To schedule cooling services from King, contact us today. Or, give us a call at (708) 687-6898.

We Employ NATE Certified TechniciansWhat is NATE-certification, anyway?

The North American Technician Excellence (NATE) program is the nation’s premier training, certification, and resource center for HVAC companies.

Founded in 1997 by a coalition of HVAC and service companies, NATE has helped improve customer satisfaction rates; reduce the return of improperly installed equipment; and more. Basically, NATE has changed the game.

Through NATE, HVAC technicians are not only trained, but they’re also thoroughly tested and vetted to determine whether or not they’re ready to go out into the field. NATE-certified technicians represent the pinnacle of the industry, and that’s why King Heating, Cooling & Plumbing hires them.

Why does being certified matter?

Your air conditioner and furnace are advanced, complex machines. They need a professional inspecting, repairing, or installing them. After all, you wouldn’t want just anyone handling your auto repair. The same thing goes for your HVAC units.

However, some HVAC businesses like to save money and cut corners by hiring techs who are inexperienced. That basically means that, at best, they’re learning on the job—with your air conditioner as the training exercise. Yikes! At worst, they could be completely out of their depth and making major mistakes.

At King, we recommend only have professional, experienced technicians inspect or repair your HVAC units. Our NATE-certified techs give you the peace of mind of knowing that you don’t have some random guy working on your system. Instead, you have a true, trained professional.

Why trust King?

King Heating, Cooling & Plumbing has been serving the communities of Oak Forest, Orland Park, Frankfort, and Joliet since 1968. We’re a full-service HVAC business that is locally trusted: we’re a seven-time winner of the Chicago Tribune’s “Best of Chicago’s Southland” award.

Recently, King won the 2017 Better Business Bureau Torch Award for Ethics—one of the highest honors the BBB can bestow upon a business. We’re also a seven-time Carrier President’s Award winner. Finally, we’re HomeAdvisor Screened & Approved.

Beyond our awards, we’re a local business with great customer reviews and a 100% satisfaction guarantee. When you need HVAC, plumbing, or other kinds of home services, there’s only one team to call: King.
