During the hot summer months, most homeowners don’t expect to find ice on their air conditioning unit. Unfortunately, this issue is more common than you might think, and having ice on your AC is a sure sign that something’s not right. Reviewing the likely causes can help you get your equipment back to its normal working state.
Problems with AC Ice
Once you notice that there’s ice on your unit, you need to turn your AC off. This can help prevent the situation from getting worse. Assuming it’s warm outside, this will help get the ice to melt, too. Let your unit thaw completely, then work through these different scenarios to identify the underlying cause.
1. Poor Airflow
If you’re lucky, the ice on your AC is the result of a more minor issue. After the ice has thawed, the first thing to do is to check is your air filter. Sometimes ice can form on air conditioners when there is poor airflow, so replacing your old air filter with a new one might be all it takes to get your unit running smoothly again.
One of the problems with dirty filters is that they put more stress on your evaporator coil. Reducing airflow over your evaporator coil can then cause your equipment’s temperature to drop below freezing. Consequently, humidity will start to collect around your AC and turn into ice.
Hopefully a new air filter will be enough to remedy the situation. To test this, wait for the ice to melt and then turn your air conditioner on again to see if the ice returns. If it doesn’t—then you’re all set. But if the ice comes back, there might be another problem.
2. Dirty Evaporator Coil
When ice forms even with a new air filter, you might be dealing with a dirty evaporator coil. This can happen with older units or AC equipment that hasn’t had regular maintenance.
In this case, you’ll want to turn the equipment off again and call on an expert to come clean the evaporator coil. Unfortunately, this isn’t something that homeowners can do on their own. The process requires a tech to fully removing the indoor coil to clean it, before re-installing.
Continuing to run your AC unit when this part isn’t working properly can cause a chain reaction of other issues. Rather than risk damage to your compressor or other AC parts, it’s best to call your local HVAC company to take a closer look. Odds are, they’ll be able to remedy the situation pretty quickly with by either cleaning your evaporator coil. Otherwise, they might have to take a look at your refrigerant levels.
3. Low Refrigerant
Systems that have low refrigerant aren’t able to keep the evaporator coil within the proper temperature ranges. If you have an issue with refrigerant—and not the coil itself—your AC unit probably has a leak.
Simply topping off the refrigerant isn’t usually enough to fix the issue. In fact, if you just add refrigerant without testing for a leak first, you might just be wasting money. Depending on the leak size, it could take several months of just a couple of days to have the problem come back. So, it’s a risk. (Plus, companies don’t provide a warranty on refrigerant, especially without a leak search and repair.)
For these reasons, it’s important for your HVAC technician to check for leaks whenever your refrigerant levels are low. If your tech can find the leak and repair it, you’ll be able to avoid other costly replacement parts. A detailed review of your system can help you figure out what’s wrong.
4. Broken Motors
The last reason you might have ice on your AC unit is if a blower motor or your fan motor is going out. These issues can also cause your system to freeze up due to restricted air flow. (Though this is different than poor air flow just from a dirty filter.) As with dirty evaporator coils and refrigerant leaks, if your motor has gone out, you’ll need an HVAC tech to come by for some repairs.
Time for AC Repair?
As soon as you realize that there’s ice on your AC unit, remember to turn your system off. Continuing to use your home’s air conditioning can just make matters worse. Replace your air filter as the ice thaws. That way, if the ice returns, you’ll know you need to call your local HVAC company to take a peek inside the unit.
If you’re located around the Indianapolis area, know that our team at LCS Heating and Cooling has got your back. We’re here to help you out whenever you notice issues with your AC in the summertime.

Check-ups for your kids, any pets, and the car all have their purpose. You want to make sure everything is working as it should, and your preventative HVAC maintenance isn’t much different. Scheduling regular, preventative maintenance for HVAC equipment helps homeowners stay “in the know” on their system.
Before the seasons switch, make an appointment with your local HVAC company to make sure everything is okay with your cooling system. No one wants to wake up to a broken AC unit right when the weather starts heating up! Make sure your technician reviews the following on your system (and with you) for a job well done.
What’s Covered in Your Cooling Tune-Up?
Your annual maintenance process should always include a detailed review of the inside and outside components of your cooling system. It’s important to get an AC tune-up done once a year to prevent unnecessary issues. Scheduling your service during the cooling season can help you get the best benefits!
There are many different technical parts to review in your unit. Testing each of these areas takes a little time, but going through them one-by-one will help your technician identify any air conditioner problems that may occur. If you can isolate errors to a single step in your system’s process, it will be easier to keep repair costs down and extend the lifespan of your AC unit. Your cooling tune-up should always include tests for:
- Check operating pressures and temperatures
- Superheat measurements
- Temperature drop at return and supply air
- Contactor condition and operation
- Proper operation of controls
- Wiring and electrical connections
- Fan and inducer motor voltage and amperage
- Function of capacitors and relays
If all of those tests are completed in good working order, your tech would then move on and perform steps for ongoing maintenance. Because dirty units won’t be able to run properly, these items are very important for every tune-up. A few more details can help keep your system running at peak efficiency:
- Lubricate blower motor, condenser fan, and other moving parts (if needed)
- Clear the condensate drain for overflow protection
- Clean outdoor condenser unit for proper airflow
The final steps on the check-list relate to customer care. Your technician should always be ready to review your key concerns about your AC’s operation and be able to address the following for a full-service review:
- Check thermostat and adjust (if needed)
- Evaluate air filters, and clean or replace (if requested)
- Review equipment condition and answer any questions
If your HVAC technician can complete the following, you will probably be all set for annual maintenance. As the old adage goes, “An ounce of prevention is worth a pound of savings!”

Not sure who to call when the AC breaks down? You’re not alone! Deciding which HVAC company to go with can be a confusing process, but things get a lot simpler when you work in stages. If your AC isn’t working quite right, or you’re thinking about a system upgrade, take a look at these checklist items first. A little research can help you find an HVAC company you can trust.
Part I: Examining Your AC Unit
Whenever you can, try to check on a few things with your unit before making a service call. Sometimes a quick fix is all you need to solve the problem.
- Check the thermostat. This is often the first place we go, but double-check to make sure it’s set correctly. If the thermostat screen is blank, that might mean you need to replace the batteries (if it takes any).
- Replace your air filter. Hands down, the best way to keep your HVAC unit in good order is to regularly change your filter. Old filters restrict air flow and can even stop your system from working if they’re dirty enough.
- Clear the area around your AC unit. Landscaping debris might be blocking the air flow around your system. Make sure the unit can run properly and efficiently by cleaning up, and then confirm that the breakers are turned on.
If nothing has changed after taking those steps, it might be time to call in a professional. Try to make a couple notes on your unit’s symptoms so you have all the information you need to schedule the visit. Strange noises with your HVAC unit, odd smells, and any new cold or hot zones in your home are all indicators that your system needs servicing.
Part II: Finding a Reputable HVAC Company
So you’re ready to bring in the professionals, but not sure who to call? You’ll be more likely to find a great HVAC company when you stick to a few guidelines.
- Ask your contacts about recent service. Try posting a status update on social media to say you need service. Your friends and family will be happy to tell you about their last HVAC experience—whether good or bad, you should easily be able to get a few first-hand accounts about local companies.
- Read online HVAC reviews. More and more people are using Yelp to review HVAC companies. If you have a company you’re thinking of calling, check out a few of their reports first. It’s a good sign if customers are praising their HVAC repairs, not just the system replacements. That usually means the company is honest (because they’re not trying to up-sell) and works with your best interests in mind.
- Confirm that the company is bonded, insured, and licensed. The City of Indianapolis requires a permit for replacing an air conditioner. Visit your HVAC company’s website to make sure they are licensed in your area. Working with a company that’s bonded and insured will also protect you from any complications that might happen during a service call.
When it comes to HVAC repairs and new installations, a company’s experience matters a lot more than their location. Your best option may not always be the company that’s closest to you, so feel free to check credentials in a wider radius.
Part III: Reviewing Your AC Service Call
Once you’ve selected a company to try out, pay close attention to how they handle your service during their visit. Comparing etiquette is often just as important as comparing price!
- Was the technician professional? Using shoe coverings in your home and cleaning up around the worksite are signs of good employee training.
- Is the company’s pricing straight-forward? Having a flat-rate fee for service calls is standard practice, but it’s an added bonus if your HVAC company says they’ll waive the service fee if your system needs more expensive repairs.
- Did your technician explain the next steps? A good tech will tell you exactly what they checked and be able to confidently answer all of your questions. If they said a certain part on your unit needs replacing, they should also tell you whether it’s covered under warranty.
Last but not least, be sure to trust your instincts when hiring a new home services company. Doing your research is definitely a plus, but sometimes you’ll just know a good thing when you see it. If you’ve already vetted your new HVAC company, the only other thing you can do is to go with your gut!
The last thing on anyone's mind right now is HVAC. It's too warm to need the furnace and too cool to need the air conditioner. We do live in Indiana though so that can change in just 24 hours! We want to provide some tips for things you can do on your own to keep your furnace and air conditioner running at its best. We present the LCS Top Ten of Homeowner DIY HVAC Tips:
10. During cold or hot months, keep the programmable thermostat set within 3 degrees of each setting. A furnace and air conditioner will have to run for a very long time to make up the temperature difference. If you have an electric furnace
and heat pump, the electric furnace will come on as well to reach the set temperature. Since an electric furnace runs at a higher cost, it counters the savings that you might have had with the lower initial temperature.
9. Keep the weed eater and lawn mower away from the control wiring of the air conditioner. The wiring should not be hanging down but if it is, be careful when mowing and weed eating. It's not a high voltage wire but if it gets cut with a weed eater or mower, you can get shocked and it can take out the air conditioner. If the wiring is loose or hanging down, tie it up with electrical tape or have a technician tie it back when they're out doing annual maintenance.
8. If you are experiencing high utility bills, call the gas or electric company first. Ask the utility company if there's been an increase in the therm or electric rate. Ask if your bill compares to the average of others in your neighborhood. You can get great information about what your utility bill should be running. If there isn't a good reason for the higher bill, then it might be time to have a technician out to make sure the system is operating properly.
7. Move furniture away from registers. It's not uncommon to see a couch over a register or a bookcase pushed up against a register. Not only can the heat dry out your furniture but it also prevents the air from properly traveling throughout the rooms.
6. Keep registers open. A very common problem in two story homes is a temperature swing between the upstairs and downstairs. Homeowners try to fix this problem by closing registers upstairs or in some rooms. Keep the registers open. Closing registers can restrict air flow and cause the furnace to run hot. This can ultimately shorten the life of parts inside the furnace such as motors. It can also make the air conditioner freeze up by reducing the volume of air that the system needs to expel throughout the house. This is comparable to running the system with a dirty filter.
5. If you notice a noise, smell or problem, call on it right away. If you notice something unusual, don't ignore it. It's rare that an HVAC issue will go away or resolve itself. Noises and smells often mean that a part is getting weak or going out. A little critter could also have gotten inside. Address these issues before your furnace or air conditioner goes completely out. It's no fun being without heat on a cold day or without a/c when it's hot out!
4. Keep dogs away from the air conditioner. Animal urine will degrade the a/c fins. There's not much that can be done to fix the fins once this happens so it's best to make sure the fur babies stay away.
3. Replace the batteries in the thermostat. If the thermostat goes blank, check to see if there are batteries that need changed. Not all thermostats have batteries, but if it does, it's likely AA or AAA batteries that need changed.
2. Pick up leaves that are around the air conditioner or heat pump. Leaves, cottonwood, branches, etc can gather around the air conditioner. Keep these things cleaned away so the outdoor unit can breathe.
1. CHANGE THE FILTER! This is the number one thing to do to keep your furnace and air conditioner running efficiently! A dirty filter causes restricted air flow and can ultimately cause the system to stop working. If you have a 1" filter, check it once a month. If you have a 4-5" filter, check it every 3 months. It may not need to be changed at that time but it's good to check it to make sure. It's also a good idea to keep extra filters at the house. That way, you always have one on hand when it's time for it to be changed.
A couple of other tips are to caulk or re-caulk around windows and doors. It's also a great idea to check the insulation in your home. If you don't have at least 12-15" of insulation in the attic, you'll want to consider adding more!
Keeping up on these things can not only save you money but can save you from the inconvenience of being without heating or cooling during those hot and cold months. HVAC equipment is definitely an investment. Protect your investment by following our Top Ten tips!
We get lots of questions regarding HVAC maintenance. This is a good thing! It means people care about their HVAC investment. Since we're entering air conditioner season, let's focus on questions relating to air conditioner maintenance:
- What is air conditioner maintenance? Preventative maintenance is completed on the a/c to ensure that it is running properly and as efficiently as possible. The air conditioner is cleaned and there are many components that are checked. If a reading is off or out of range, the homeowner will be made aware. Keeping the air conditioner clean also ensures proper air flow.
- Can I turn my air conditioner on before maintenance has been completed? Yes! The air conditioner can certainly run before maintenance is done. Keep in mind that maintenance keeps it running as efficiently as possible.
- What months do you schedule maintenance? We generally start scheduling maintenance mid-April, depending on the weather, and continue to schedule throughout the summer. It's more important that maintenance is done each year rather than it being done a specific week or month.
- Can the service be completed if it's raining? We will reschedule your maintenance appointment if it's raining or below 60-65 degrees outside. Although the techs do have raincoats, we don't want some of the tools and gauges out in the rain. We also don't want your a/c exposed to the moisture. The new R-410 refrigerant attracts moisture 10 times more than the old R-22 refrigerant. We don't like to take chances, so we'll always reschedule if it's raining. In addition to being dry outside, it also needs to be at least 60-65 degrees outside. If it's colder than that, the temperature drop and readings could be inaccurate. Accuracy is key, so we will reschedule if it's too chilly outside.
- How will I know what the technician does during the service? The technician will complete an invoice detailing everything that was completed during the maintenance service. He will also let you know how everything looked and answer any questions you have about your system.
- How much does an annual maintenance plan cost? Our plan is $150 per year. That includes the maintenance service on the a/c in the spring or summer and the maintenance service on the furnace in the fall/winter. Other benefits included with the plan are: No service call if a return visit is needed within 30 days, $10 off service call, 15% off repairs, 15% off indoor air quality (humidifiers, filters, thermostats, UV lights, etc) and no overtime rates if service is needed in an evening, weekend or holiday.
- Does maintenance guarantee that my air conditioner will not break down? Air conditioners are machines and can break down at any time. That being said, there are issues that can be found during maintenance and either repaired at that time or at least brought to the homeowner's attention. For example, the technician may see that a motor reading is in range, but on the high end. While it doesn't necessarily need replaced at that time, the homeowner can be made aware that the motor is on it's way out. It could last another week or it could last another 6 months. In any case, the homeowner is now aware.
- Will you change my filter while you're here doing maintenance? Absolutely! If you already have filters, we will gladly change it for you. If you don't have filters, we can provide you with the price to bring one with us. We also have an online filter program in which we can provide you with a code to order your filters online and have them delivered to your door. Shipping is free and you'll always have your filters on hand.
- What if I have two HVAC systems at my house? We can put each system on the annual maintenance plan. We'll schedule a longer period of time to be at your house to complete maintenance on both air conditioners (and same in the fall/winter for the furnaces). The second system would be $10 off ($150/$140 for two plans).
- Do I need to be home when you do the air conditioner maintenance? Preferably, yes. We will need access to the thermostat and furnace area so will need inside the house. If you have a lockbox or garage code, we can enter that way but always prefer having someone home so the technician can answer any questions while he's there.
Hopefully, we answered some of your questions about air conditioner maintenance! If not, feel free to contact us as we're happy to discuss.
We've had one of the coldest winters on record here in Indianapolis so it seems everyone has spring fever! With the arrival of spring comes a whole checklist of home maintenance items just waiting to be done. Here's a list of items that you can do around your home
