Frozen Coils

Frozen coils or coil is an issue with an AC unit that can occur, even in the hottest months. Even though it may be the evaporator coil that froze. When this occurs, cooling ceases and the system can fail. Four primary reasons — airflow blockage, refrigerant leaks, dirty components, and mechanical failures.

1. Airflow Blockage

Low airflow is the number one cause for frozen coils. Test air filters frequently—filthy ones clog air and have to be dislodged every 30–90 days. If you find ice in the morning, a faulty thermostat may be at fault, particularly following cool nights. Ensure nothing obstructs vents or registers, including rugs or large furniture, and inspect ductwork for leaks or bends. Remove any debris from around the outside unit so air can flow freely.

2. Refrigerant Leaks

If you hear a hissing sound or observe frost on the refrigerant lines, you might have a leak. Low refrigerant drops the pressure and the coil then gets too cold, which is where the ice comes from. This not only hikes cooling but energy bills as well. Always confirm refrigerant levels are per manufacturer specifications. If you suspect a leak, turn it off and call a professional immediately.

3. Dirty Components

Coils and filters become filthy fast, particularly with animals or a ton of dust. Have your evaporator and condenser coils cleaned on a regular basis, or clean them yourself with a special solution and soft brush. Replace or clean your air filter every month. Make sure the drain pan and line are clear so water flows away and doesn’t freeze. Keep your outside unit free of leaves and dirt to make it work better!

4. Mechanical Failures

Issues such as a malfunctioning thermostat, defective compressor, or failing fan motor can induce freezing. Electrical issues cause havoc. If coils freeze sporadically, the thermostat may be misinterpreting the room temperature.

5. Weather Impact

High humidity in the summer puts added strain on the AC and can result in freezing. Spring pollen or dust gunk up filters, blocking airflow. Big temperature swings are hard on the system. Routine upkeep ahead of the hot or cold seasons keeps your AC going smooth.

Homeowner Actions

These homeowner actions don’t simply resolve the problem—they contribute to securing your home, optimizing performance, and managing expenses.

Thaw Unit

1. Cut the AC at the thermostat and circuit breaker.
2. Allow the ice to dissolve. Surround the unit with towels to catch water.
3. Install fans close to the area to expedite thawing without direct heat.
4. Don’t ever use a hairdryer or heater. Sudden warmth can damage parts.
5. Once defrosted, check for any residual ice or water puddles.

Fans circulate the air and speed thawing, but steer clear of anything that propels hot air. Inspect the system for any residual ice before rebooting. If you notice additional ice following a full thaw, it could be a sign of a larger issue requiring a pro.

Check Filter

Remove the air filter. Hold it up to a light—if you can’t see through, it’s clogged. Change the filter if it’s dirty or been in over a month. High-efficiency filters trap more dust and aid air flow better and contribute to cleaner indoor air.

Set reminders to change filters every 1–3 months – particularly in winter when systems are working harder. Clean filters not only keep your AC healthy, they save you money on energy bills and keep air clean for all of your little gremlins inside.

Inspect Vents

Check all supply and return vents. Dust and blockages restrict airflow, causing the AC to work harder and ice up. Ensure that every vent is unobstructed—relocate furniture or rugs, if necessary.

Vacuum or dust vents to prevent dust accumulation. Direct vents to blow cool air to the rooms you need it in, which evens out the temperature in every room.

Even during off-seasons, vent covers can hold back the dust and junk. Taking out screens and installing storm windows before winter keeps the system secure.

Reset System

Turn off your AC entirely. Pause for five minutes, then turn it on again. This allows time for all components to recover.

Once you’ve restarted, keep an eye on your AC for strange noises or new ice. As always, check your manual for model specific steps.

Libertyville Climate

Libertyville contends with sweltering, humid summers and harsh, blustery winters. These swings imply that we require HVAC systems that are adaptable and can maintain equilibrium indoors. Trusty heat and AC isn’t just a luxury, it’s a necessity — particularly because federal guidelines mandate that your systems have at least 80% efficiency. Homeowners enjoy the greatest comfort and utility when they customize home cooling and heating to accommodate the area’s cycles.

Summer Humidity

Libertyville’s high humidity summers translate to more moisture in the air, causing rooms to feel warmer than they really are. This additional moisture can strain ACs, causing them to work harder — which in turn sometimes causes freezing, or less efficient cooling. Running a dehumidifier alongside your AC can extract water from the air, improving comfort while reducing stress on your system.

Adjusting your thermostat a bit warmer than normal helps when it’s muggy out. This keeps the air cool without overworking the AC. Sweat it out during peak humidity, like July and August, with these regular checks and you’ll keep your system running smooth. That way, HVAC techs can spot early signs of trouble, like frost on coils, so you don’t get stuck with a frozen unit.

Spring Pollen

Spring is a rush of pollen that can get caught in filters and clog them up. Weekly cleaning–dusting, vacuuming, and wiping surfaces–reduces accumulation. When pollen is high, change your air filters every two to four weeks so the AC continues to pull air without stress.

It assists in keeping windows and doors closed on high pollen days. This prevents grains from entering and aggravating allergies. Air purifiers are another solid step if you want to scrub indoor allergens, keeping air fresh when pollen levels surge.

Temperature Swings

Gusty hot-to-cool or cool-to-hot shifts are a Libertyville staple. Prior to these swings, have your HVAC pro give the system a once-over—once in spring, once in autumn. These inspections ensure your AC’s prepped for heat waves and your furnace can power through cold snaps.

Smart thermostats keep you at the right temp, regardless of the outdoor conditions. They tweak settings as the weather shifts, conserving energy and stabilizing things indoors.

Beyond The Fix

AC systems freezing up is only half the story. Your back’s long-term comfort and efficiency require more than a quick fix. Homeowners across the board encounter these problems—clogged sinks, winter pipe freezes, or even radiator bleeding. Preventive care and smart upgrades are the name of the game. Routine inspections, maintenance and perhaps exploring efficient replacements or air purification can go a long way in a healthier home.

Performance Audits

1. Examine system parts and look for leaks, obstructions, or deteriorated parts.
2. Test thermostat settings, temperature output, and energy use logs.
3. Audit output to identify vulnerabilities—perhaps missing insulation, outdated filters or recurring clogs.
4. Address problems as suggested by audits, such as sealing leaks or modernizing controls.
5. Just put in reminders for audits every year to keep things running smooth.

A performance audit ain’t just a list. It’s a means to discover the true problems that impact comfort and waste energy. Take, for instance, a blocked sink or slow radiator bleed — while they seem small, they can signal larger system deficiencies. By maintaining a fixed audit routine, homeowners can catch issues when they’re still small—before they become costly fixes or energy drain.

Efficiency Upgrades

Studying upgrades is a wise thing to do if you’re trying to save money and be comfortable. Programmable thermostats assist in setting cooling schedules, so the AC isn’t blowing when no one’s around. High-efficiency ACs or heating units are a must, particularly in regions with freezing winters and scorching summers. Good insulation and sealing saves a lot of energy — keeping heat in during winter and cool air in during summer.

Indoor Air Quality

Air quality counts for health and comfort. Air purifiers are able to eliminate allergens, which is beneficial for individuals suffering from asthma or allergies. Duct cleaning prevents dust and debris from accumulating in the air you inhale. Humidity checks are small but essential–too much invites mold, too little dries out airways. Choose HVAC filters of appropriate size and MERV rating for optimal performance. Understanding your options—think HEPA purifiers or UV cleaners—simplifies the process of selecting what suits you.

Remember, a well-tuned system—descaled, cleaned, and leak checked—results in better air and fewer breakdowns.

Your Next Steps

When your AC begins to freeze up, your best bet is to react quickly and identify the cause. There’s no single cause for this issue–occasionally it’s a dirty air filter, and sometimes it’s a refrigerant leak. Both can bog down your system, increase its power consumption and make your indoor air less healthy. In regions where the air is hotter and more humid, a frozen unit becomes apparent immediately. In temperate climates, a minor lowering of room temperature—perhaps only a degree or two—could easily be unobserved. Still, that minor shift can cause bigger repair costs over time and make your home less cozy.

Arrange a service call with a trusted technician the moment you notice any icing or drops in cooling. A pro will inspect all the major components, identify leaks, and clear blockages that prevent your system from operating properly. Well-trained techs don’t only look at what’s gone wrong. They search for symptoms that have the potential to become larger problems down the line. This step is vital, since addressing a minor issue now can spare you major headaches and costly repair bills down the line.

Establishing a basic routine to care for your AC can prevent these problems before they begin. The key is to swap out your air filters on a schedule. This keeps air circulating, prevents dust accumulation, and assists your AC in running more energy-efficiently. Adhere to a filter swap out every one to three months, or more frequently if you have pets or allergies. Watch your indoor humidity too. Try to target air moisture levels somewhere between 30–50%. This bandwidth assists your AC function more efficiently and maintains the air within your home sanitary.

Keep up on your system. Recognize the symptoms of trouble, such as weird sounds, weak air pressure or elevated electric bills. Don’t run your AC more than necessary – it wears out parts and can send bills through the roof, especially when the temperature’s high.
