If you have ever walked into your home and noticed a strange odor coming from your air conditioning unit, you are not alone. A weird smell from your AC can make your whole house feel uncomfortable. While it may be tempting to ignore it or cover it up with air fresheners, strange smells are your system’s way of warning you that something is wrong. When it comes to AC repair, ignoring these signs can turn small issues into costly problems. That is why calling a professional like Service Hero can make all the difference.
We had a main line drain clog under the house. Russell was our technician and approached the problem from outside the house, working retrograde from a trap in the front yard. I was skeptical but it worked when my efforts with a cable inside the house had failed. He was very professional and pleasant to deal with. We asked him to install a cleanout closer to the house for future use and we were very satisfied with the work.
Tyler is the best! He came to our parent's house, knew exactly what the problem was, and explained it to us without the typical guesswork. I'd recommend him any time you need a good plumber.
Overall, It was a very good experience with the Service Hero team. I was able to schedule an appointment late in the night. They are truly 24x7. The help desk team was very professional, courteous, and friendly. All responses were timely. The field technician showed up on time and diagnosed the issue accurately. Kudos to the Service Hero team!
A musty or damp smell is one of the most common issues homeowners face. It often means there is moisture where it should not be, such as inside the ducts or around the evaporator coils. When condensation is not draining properly, mold and mildew can grow inside your system. Every time your AC turns on, it blows that musty air throughout your home. This not only affects air quality but can also be a sign that your system needs cleaning or professional inspection by an HVAC company. Mold in your ducts can trigger allergies, headaches, and other breathing issues, so it should never be ignored.
If you ever notice a burning smell when your air conditioner kicks on, turn it off immediately. That odor could mean that something electrical is overheating, such as wiring, a motor, or a fan. In some cases, it might be a worn-out belt or debris stuck inside the unit. A burning smell should always be taken seriously because it can be a fire hazard. Once the system is off, contact a licensed HVAC company in Brea, CA to inspect it safely. Service Hero technicians often find that these problems start small, like frayed wiring or dust on the motor, but can quickly turn dangerous if ignored.

Few things are more unpleasant than a rotten egg smell coming from your vents. If this happens, it might not even be your AC itself but a gas leak nearby. Natural gas has an additive that smells like sulfur to warn people of leaks. In this case, leave your home immediately and call your gas provider or emergency services. Once the area is cleared and safe, schedule AC repair if your unit was affected. Professionals like Service Hero can check whether the smell came from the air system or another source in your home.
If your AC gives off a sweet or chemical-like odor, that can indicate a refrigerant leak. Refrigerant is what helps your AC cool the air, but when it leaks, it can create an odor that smells somewhat like chloroform or paint thinner. This can be harmful if inhaled over time. A refrigerant leak also means your system will not cool efficiently, and your energy bills may rise. Calling an experienced HVAC company is the safest and most effective way to fix the problem. Technicians from Service Hero can locate and repair the leak, then recharge the refrigerant so your system works like new again.
Sometimes the issue is as simple as dirt. A dusty or stale odor can occur when your air filter is clogged or your vents are full of debris. Each time your AC turns on, it blows those particles through the air. The smell might fade after a few minutes, but that does not mean the system is clean. Replacing filters every one to three months can reduce these smells and keep your home’s air healthier. However, if cleaning your filter does not help, it may be time for a deeper inspection. A professional HVAC company can clean the internal parts of your unit and make sure your ductwork is not contributing to the odor.
Your AC should never smell like smoke or exhaust. If you detect either, shut it off right away. This could mean the compressor or motor is overheating, or oil is burning inside the system. Sometimes debris can also get trapped near the fan or coils and cause a smoky smell. These types of problems require immediate AC repair, since running the system can cause serious damage. Service Hero experts are trained to handle such emergencies safely and can check whether the issue is electrical, mechanical, or due to a blocked component.
Many people try to ignore smells from their AC because the system still runs. However, this often leads to larger and more expensive repairs later. Mold can spread, wiring can short out, and leaks can damage key parts of the system. The longer you wait, the more likely it becomes that your AC will need major servicing or full replacement. A quick inspection by a trusted HVAC company can often solve the problem early and save you hundreds of dollars. Service Hero recommends regular maintenance checks to prevent small issues from becoming big ones.
If your AC is giving off any strange odor, do not take chances. Turn off your system and contact a professional as soon as possible. Even if it seems minor, such as a faint musty or dusty smell, it is better to be safe. Professionals can quickly tell whether it is a simple filter issue or something more serious. Ignoring the problem can not only shorten the life of your air conditioner but also affect your indoor air quality and health.
Your air conditioner should make your home feel fresh and comfortable, not fill it with unpleasant smells. Paying attention to these warning signs can help you act before real damage occurs. If you ever notice burning, moldy, or chemical odors coming from your AC, it is time to schedule an inspection and possible AC repair. Regular tune-ups can keep your unit running smoothly and prevent most odor-related issues before they start.
If your air conditioner smells unusual, it is your system’s way of asking for help. Do not ignore it. Reach out to a trusted HVAC company like Service Hero to inspect, clean, and repair your system before the problem worsens. With professional care, you can restore clean, fresh air throughout your home and keep your cooling system running efficiently all season long.
