What to Do When Your AC Thermostat Stops Working in Bartow

Coming home in the middle of summer only to find your AC blowing warm air can be frustrating, especially in a hot and humid place like Winter Haven. When your AC stops doing its job, temperatures indoors can rise quickly, leaving your living spaces stuffy and uncomfortable. Whether it's late in the afternoon or the heat is just starting to build, prompt action is necessary to restore that much-needed cooling.

‍

Sometimes the cause is simple, like a dirty filter or a thermostat that's been bumped. Other times, it points to a more serious issue that needs professional help. Either way, letting the issue drag on can make the problem worse. Before the temperature in your home becomes unbearable, it's smart to look into what may be triggering the problem and figure out what steps to take next.

‍

Common Causes of AC Blowing Warm Air

‍

If your AC is running but the air feels warm, there’s usually a technical reason behind it. Most of the time, one or more system components simply aren’t working the way they should. Some problems build up over time with little warning, while others stem from just one malfunction. Here are the most common reasons your AC might stop cooling:

‍

- Low refrigerant levels: This usually signals a leak. Without enough refrigerant, the system can’t cool the air properly.

- Dirty air filters: When filters get clogged with dust and debris, air can’t flow freely. That puts extra pressure on the system and reduces cooling ability.

- Thermostat issues: It might sound obvious, but the thermostat may be set incorrectly, or it might not be working at all.

- Blocked or dirty condenser coils: The outdoor unit needs to release heat. If the coils are covered in dirt or leaves, the heat stays trapped.

- Electrical problems: Faulty wiring or a tripped breaker can disrupt power to parts of the unit, keeping it from running as designed.

‍

Each of these problems can lead to warm air blowing through your vents. For example, if your child adjusts the thermostat settings without telling you, the air conditioning mode might get switched off. That can leave you wondering what went wrong until you check the settings and realize it's switched to heat or fan only.

‍

While some of these can be spotted by taking a quick look at your system, others are hidden and require the experience of our professionals to diagnose properly. Ignoring these issues puts more strain on your system, eats up energy, and drives up your utility bills.

‍

Immediate Steps to Take

‍

Before calling for help, there are steps you can take on your own to see if the problem is a quick fix. This doesn’t mean trying to repair complicated components, but it does help to rule out minor issues first. Here’s what to check:

‍

1. Check your thermostat: Make sure it’s set to cool and not fan or heat. Also, ensure the temperature setting is lower than the actual room temperature.

2. Inspect the air filters: If they look clogged or heavily coated in dust, it's time to replace them. A blocked filter restricts airflow and could be an easy fix.

3. Examine the outdoor unit: Look for any debris like leaves, grass, or dirt packed around the unit. Clear away anything blocking airflow.

4. Look at the breaker box: Check to see if any breakers have tripped. If so, safely reset them and monitor for any change in performance.

‍

These checks don’t require tools or technical know-how and can save you both time and money. That said, if your system is still blowing warm air after going through these steps, it’s time to reach out for AC emergency repair in Winter Haven. Warm air usually means something isn’t circulating or transferring heat correctly, and that’s not always obvious until a full inspection is done.

‍

When to Call for AC Emergency Repair in Winter Haven

‍

If you’ve already run through the basic checks and your AC is still sending out warm air, that’s a signal to stop troubleshooting and bring in our technicians. Some problems are too complex or risky to tackle without the right training. For example, refrigerant issues not only impact cooling efficiency, but also present health and environmental hazards if handled incorrectly.

‍

There are also other signs that point to a more serious internal failure. These include loud grinding or squealing sounds, frequent cycling where the unit turns on and off too often, unusually high power bills, or the AC failing to turn on at all. These symptoms often suggest a failing compressor, a short circuit, or internal damage to critical parts. Waiting too long to act could damage the system further.

‍

Calling for AC emergency repair in Winter Haven makes more sense when you’re dealing with a home that’s no longer staying cool no matter what setting you use. During the height of summer, every hour without working AC feels longer, and the indoor air can quickly become uncomfortable or even unsafe for kids and older adults.

‍

Smart AC Habits to Prevent Future Problems

‍

Once your system is back to blowing cool air again, it helps to make a few changes that can prevent another breakdown. Warm air problems often come out of nowhere, but most of the causes are preventable with consistent care. Taking a proactive approach is one of the easiest ways to avoid unexpected repair costs and system wear-down.

‍

Here are a few habits that can extend the life of your AC and help it run better:

‍

- Replace air filters every 1 to 3 months, depending on how dusty your home gets or if you have pets.

- Rinse or brush away any leaves, grass, or buildup from around the outdoor unit monthly.

- Keep return vents and supply vents open and clear of furniture or curtains.

- Have our technicians inspect the refrigerant level regularly to catch leaks early.

- Schedule routine maintenance before the hot season begins to identify small problems early.

‍

A good rule of thumb: if the unit doesn’t seem to work as easily as it used to, it’s time to give it attention. Whether you notice longer run times or uneven cooling between rooms, these are early signs that shouldn’t be ignored. Small fixes handled on time are almost always less expensive than emergency repairs after a system failure.

‍

If your AC isn’t keeping your home as cool as it used to, there could be a leak in the evaporator coil. This is a problem many homeowners in Auburndale face during the peak of summer. When there's a refrigerant leak, your system can’t absorb heat properly, which means warmer air, longer run times, and higher power bills. It’s a frustrating issue, especially on days when you just need a break from the heat.

‍

Evaporator coil leaks don’t just show up overnight. They tend to happen gradually, and by the time you notice something has changed, it may already be affecting your system’s performance. Knowing what your coil does and how to spot early signs of trouble can save you from stress, discomfort, and unexpected repair costs. If you know what to look for, you can catch problems before they get worse.

‍

Understanding Your AC Evaporator Coil

‍

The evaporator coil sits inside your indoor AC unit and is responsible for cooling the air before it flows into your home. It contains refrigerant, which absorbs heat from the indoor air. When everything is working properly, this process keeps your space comfortable, even during Auburndale’s hottest months.

‍

But things can start to go wrong without warning. As the coil takes in warm air and cools it, any damage to the tubing or metal surface can cause refrigerant to leak out. When there's less refrigerant than there should be, your system has to work harder, and your home doesn't stay as cool. It becomes especially noticeable when the AC starts running longer than normal or the air from your vents no longer feels cold enough.

‍

There are a few signs Auburndale homeowners should watch for that may indicate a leaking evaporator coil:

‍

- Weak airflow from the vents, even when the settings are correct

- Warm air blowing out instead of cool, conditioned air

- AC cycles running longer or turning on more frequently than usual

- Unusual hissing or bubbling noises coming from the indoor unit

- Ice buildup on the refrigerant lines or the evaporator coil itself

‍

These symptoms often sneak up gradually. In many cases, the AC will still run, but not the way it should. Some homeowners in Auburndale might dismiss them as seasonal quirks or think the heat outside is just too strong. But if these changes continue, it’s usually a sign that something inside the system isn’t holding up as it should. Ignoring the problem can leave your home uncomfortable and increase the chance of more expensive repairs.

‍

Common Causes Of AC Evaporator Coil Leaks In Auburndale

‍

Weather plays a role, but several behind-the-scenes issues are often to blame for a leaking coil. These problems don’t always show up in obvious ways, which is why they catch people off guard. Here are the most common causes of coil leaks in residential air conditioning systems around Auburndale:

‍

1. Corrosion and wear

The metal in evaporator coils can break down over time, especially when exposed to moisture and indoor air contaminants. Cleaning products, insulation materials, or even pet dander can add to the corrosion process. Over time, the chemical reactions between the air and coil form tiny holes in the tubing, causing refrigerant to leak.

‍

2. Dirty coils and lack of maintenance

When coils are covered in dust or grime, they trap moisture and become less effective at cooling the air. The added strain can lead to coil damage. Dirt buildup also encourages the growth of bacteria and mold, further increasing the chance of corrosion.

‍

3. Poor installation practices

If the unit wasn't installed properly from the start, problems may show up sooner rather than later. Misaligned connections or poor airflow design can reduce system performance, creating pressure points in the coil that lead to leaks down the line.

‍

In a place like Auburndale, where temperatures rise quickly in the summer, your AC has to work hard every day. That constant strain makes even small issues surface sooner. When systems are running daily just to keep the home cool, damage to parts like the evaporator coil can build up fast. Regular maintenance can help catch these weak points early before they grow into bigger repair needs.

‍

How A Leaking Evaporator Coil Affects Your AC System

‍

When the evaporator coil starts leaking, the first thing that suffers is your AC system’s cooling power. With refrigerant slowly escaping, the unit can't keep up with demand. Homeowners in Auburndale often notice rooms feeling warmer, even though the system seems to be running. What’s happening is the AC is working harder and running longer just to produce minimal cold air.

‍

This extra strain doesn’t just affect indoor comfort. It also leads to higher electricity use. If your system never shuts off or takes twice as long to cool the house, your monthly bill reflects it. Some residents dismiss it as a normal part of a hot summer, but if this change comes suddenly or worsens over a few weeks, a leaking coil could be the cause.

‍

More wear on the system also increases the chances of other parts breaking down. For example, the compressor may become overheated if low refrigerant levels persist. That can leave you with a more serious and more expensive repair later on. A system with low refrigerant also tends to freeze. When ice forms on the coil, airflow drops even more, and moisture can eventually leak into other components of the air handler.

‍

One Auburndale homeowner noticed the AC vents barely pushing air on a hot afternoon. The thermostat was set correctly, but the room just wouldn't cool. After an inspection, the issue turned out to be a low refrigerant level from an evaporator coil leak. Left unaddressed, that small leak would have continued deteriorating the system. In cases like this, a faster response could make all the difference between a simple repair or a full system failure.

‍

Steps To Take If Your Evaporator Coil Is Leaking

‍

If you suspect your AC isn’t cooling the way it should, it’s important to act early before the problem grows. A few steps can help prevent further damage and get your system back to working condition.

‍

Here’s what to do if you think there's a coil leak:

‍

- Keep an eye on airflow and temperature. If you feel warm air coming from the vents or notice reduced cooling, don’t ignore the signs

- Check your thermostat and air filter first. Dirty filters or incorrect settings can mask deeper issues, like coil problems

- Turn off the system if you hear hissing or see refrigerant lines covered in ice. This prevents the AC from pushing itself harder with low refrigerant

- Contact our professionals for a full inspection. A certified check will determine whether the refrigerant is low and confirm the source of the leak

- Don’t attempt to refill or patch the system yourself. Depending on the severity of the leak, the coil may need to be repaired or replaced

- Consider signing up for a maintenance plan, which includes scheduled checks that can catch leaks and other issues early

‍

Trying to run your AC through a leak can do lasting damage. Many homes in Auburndale see faster system breakdowns during the summer because people want to wait until fall to deal with repairs. But if your system is leaking now, that wait could turn a fixable issue into an emergency.

‍

Ensuring Your AC System’s Health In Auburndale

‍

A leaking evaporator coil might feel like a minor problem at first, but the longer it goes unchecked, the bigger the risks. Comfort drops, energy bills go up, and the chances of parts wearing out early start to rise. With Auburndale’s high summer temperatures, it doesn’t take much for these problems to show up quickly.

‍

The best approach is to stay ahead of the issue. That means paying attention when something feels off and scheduling inspections when signs point to a leak. Air conditioning systems work hard throughout the summer, and giving them some care now can keep you from costly surprises later. Whether it's a noise, a hot room, or frequent AC cycles, don’t chalk it up to the heat. In many cases, a hidden leak is the real problem.

‍

If your AC isn’t keeping up, there’s likely a reason, one worth resolving before it turns into a system-wide failure. Every summer, we help homeowners across Auburndale stay cool by catching these issues early and helping restore their AC’s performance. It starts with recognizing the signs and knowing when to call our technicians for help.

Mold inside your AC unit isn't just unpleasant. It can create serious problems for your home’s indoor air and your comfort. In a place like Winter Haven, where summer humidity sticks around for months, moisture buildup in an air conditioner is common. Without proper attention, that moisture quickly becomes the perfect environment for mold to thrive.

‍

Dealing with mold in your AC takes more than just wiping away what you see. Mold can spread through the ducts and filters, affecting the air quality throughout your home. Knowing how to identify it, why it’s there, and what to do about it can help keep your AC safe and your air clean.

‍

Understanding the Problems of a Moldy AC Unit

‍

When mold takes hold in your AC unit, the first thing many homeowners notice is a musty odor that doesn’t seem to go away. Mold doesn’t just impact the way your house smells. It can affect air quality and how well your AC system performs. The longer you leave mold untreated, the more it spreads. That can lead to poor airflow, clogged parts, and a system working harder than it should.

‍

In Winter Haven, the mid-year weather often brings a mix of heat and humidity, which creates prime conditions for mold buildup. Since AC units are designed to remove moisture from the air, condensation often builds up inside the unit. If there’s no regular upkeep, that moisture doesn’t dry completely, and mold starts to grow behind panels, near filters, or inside the ducts.

‍

Breathing in moldy air on a daily basis can cause irritation in your nose, throat, or eyes. If someone in your home has allergies or other respiratory issues, mold may make their symptoms worse. Even if you aren’t allergic, long-term exposure to indoor mold can trigger reactions in anyone, especially when it spreads through the AC system.

‍

Identifying Mold in Your AC Unit

‍

Catching mold early can help limit damage. Many homeowners first notice the problem when they turn on the AC and are hit with a damp, musty smell around the vents. This smell tends to linger and get stronger when the system runs for a while.

‍

Here are a few red flags to look for when checking your AC:

‍

- Musty or sour smells near vents when the system kicks on

- Dark spots around the air registers, vents, or indoor unit

- Visible mold on or near the coils, drain pan, or ducts

- Allergy symptoms that only act up when you’re inside

- AC blowing air that feels damp or stuffy

‍

Mold can hide inside parts of the system you can't easily reach. If you see mold near the surface of the unit or inside air vents, there’s a good chance it’s deeper within the system. At that point, cleaning surface areas may not be enough. A full inspection is often needed to catch mold hiding behind filters, fans, or internal parts.

‍

Causes of Mold Growth in AC Units

‍

Understanding what causes mold in the first place makes it easier to stop it from coming back. In Winter Haven, warm air mixed with indoor humidity creates a constant stream of moisture for your AC to pull out of the air. When that moisture doesn’t drain properly, it sits inside the unit and gives mold time to grow.

‍

These are some of the main reasons mold can show up:

‍

1. Excess moisture and humidity

If the humidity in your home stays high, your AC has to work harder to control it. This adds stress to the system and increases condensation. If the water doesn’t drain fast enough, it forms puddles inside the unit.

‍

2. Poor air circulation

When rooms feel stuffy or air movement is weak, it may be because mold is already slowing things down. But lack of circulation can also start the mold problem by letting pockets of moist air sit still inside the unit.

‍

3. Skipping AC maintenance

Dirty filters, full drip pans, and clogged drain lines can all create the kind of damp, dark space mold thrives in. If AC maintenance in Winter Haven is skipped for too long, these issues tend to stack up and invite mold growth without you even noticing.

‍

Even if you run the AC all summer, it doesn’t mean it’s staying clean. Indoor units need air filters changed on time and drainage systems inspected regularly. Keeping parts clean and airflow moving helps stop mold before it ever starts.

‍

Steps to Deal With a Moldy AC Unit

‍

Once you’ve confirmed there’s mold in your AC unit, the next step is to respond quickly. Turning off the AC is a smart first move. This helps stop mold spores from spreading through your air ducts and blowing into other rooms. It's important to avoid disturbing visible mold while the system is still running.

‍

Some homeowners try to clean parts of the AC unit with store-bought sprays, but that’s typically not enough. Mold may extend beyond what can be seen from the outside. While wiping down vents might reduce the smell temporarily, it doesn’t solve the root of the problem. For significant mold growth inside the system or ductwork, the job quickly becomes more than a surface-level fix.

‍

It’s recommended to let our professionals handle the removal. They can thoroughly inspect all of the AC’s internal components, reach hidden areas, and use the right gear to clean it effectively without spreading spores further into your home. Our technicians are trained to identify affected parts, clean or replace them, and treat the system without damaging any components.

‍

To support mold control in the long run, many homeowners in Winter Haven choose to install dehumidifiers or air purifiers. Dehumidifiers help reduce the moisture levels in the house, especially in areas like bathrooms or laundry rooms. Air purifiers with HEPA filters can help trap airborne mold spores and keep your indoor air cleaner.

‍

Preventative Measures With AC Maintenance in Winter Haven

‍

Stopping mold before it starts is always easier than dealing with a full cleanup. Thoughtful attention to your AC system goes a long way in keeping it mold-free, especially during the warm, damp months in Winter Haven.

‍

Here are a few smart habits to help reduce future mold risks:

‍

- Schedule regular AC maintenance in Winter Haven. Seasonal checkups provide a chance to clean key components, including drain pans and coils, before they collect too much moisture or dust.

- Replace or clean air filters once a month during heavy usage periods. Dirty filters slow down airflow and trap moisture.

- Check that the drain line is clear. If water isn't draining from your AC correctly, it may sit inside the unit and become a breeding ground for mold.

- Keep the area around your indoor AC unit dry and clutter-free. Stored items too close to the unit can trap moisture and limit airflow.

- Monitor indoor humidity levels. Keeping humidity closer to 40–50 percent can make it harder for mold to grow.

‍

Routine AC maintenance is especially important in Winter Haven homes where the system runs for extended hours during the summer. A clean, dry AC unit works more efficiently and stays healthier over the long haul. If your house has rooms that always feel more humid or musty, or if you're seeing condensation around vents, it could be time for a system check.

‍

Keep Your Winter Haven Home Mold-Free and Comfortable

‍

Mold in your AC can quickly shift from a small odor into a full-blown issue that affects the whole household. Left untreated, it impacts indoor air, spreads across the system, and may put unnecessary strain on your equipment. Taking it seriously from the start is the best approach.

‍

If you’re unsure whether your AC needs attention or you’ve noticed signs of mold, acting now helps prevent bigger problems later. Reliable, ongoing AC maintenance in Winter Haven helps reduce the risk of mold, keeps your system efficient, and protects your indoor air all summer long.

‍

If lingering mold issues are affecting your comfort, scheduling regular AC maintenance in Winter Haven with Integrity Refrigeration & A/C can help keep your system running efficiently and ensure a healthier indoor environment. For a quick estimate or to book a service visit, please contact us today.
