Commons Signs that Your AC Isn’t Ready for the Upcoming Warm Weather
Strange odors can be a cause of concern after turning on your air conditioning for the first time in the spring. If your AC smells musty when it first starts running, it can indicate dust, moisture, or other particles started building up in the months it sat unused.
We’ll discuss some common causes of odors and how to address them so your air conditioner can be ready for spring and summer. Read on for common causes of AC odors and what they mean for your system.
Dirty Filters
Clogged air filters can restrict your AC’s airflow, allowing dust and debris to circulate through the system. When this buildup circulates, it commonly produces a stale or musty smell when the unit first turns on.
You should replace your home’s air filters every 30 to 90 days, depending on the type of filters you buy. Changing your air filter regularly helps prevent restricted airflow from clogged filters and improves indoor air quality.
Dirty filters also lead to strain on your AC since it must work harder to distribute cooled air when filters are clogged.
Moisture Buildup
Another common reason your AC might smell musty upon startup is that moisture has accumulated. During the off season, moisture can collect in your AC system and cause mold or mildew growth.
When the system starts running again, the odors from the mold or mildew are circulated throughout the home. Moisture can accumulate in the coils, drain lines, or ductwork.
If you suspect moisture buildup, it’s important to have your AC system assessed by a professional. They will determine where the moisture is located and may recommend professional duct cleaning services.
Drain Pan
Your AC’s condensate drain pan collects the moisture removed from the air during the cooling process. Sometimes, aging drain pans can be worn out over time and become dirty, rusty, or cracked.
Worn drain pans allow water to sit and create odors that you smell when starting your AC in spring. A professional HVAC technician can replace your condensate drain pan when needed.
Dirty Air Ducts
Sometimes, dust, debris, allergens, and other airborne particles can build up inside your home’s air ducts. In the spring, once your AC starts circulating air again, this buildup can cause musty odors.
If you believe you have dirty air ducts, you can schedule professional air duct cleaning to remove buildup and improve indoor air quality.
Electrical Issues
Electrical issues can also be the cause of foul odors from your AC. If you smell a burning odor, it can signal a larger issue that requires immediate attention. The burning smell may indicate a problem, such as overheated components or damaged wiring. When electrical components are involved, you should call an HVAC professional immediately.
Should I Schedule an AC Repair Checkup this Spring?
If your AC smells musty upon spring AC startup, you should definitely schedule an AC checkup. An HVAC professional will evaluate your system, looking for moisture buildup, dirty air filters, clogged drains, electrical issues, and more.
During a seasonal inspection, an HVAC technician will ensure your system is operating safely and effectively before temperatures heat up. Spring is the best time for an AC tune-up, so your system is ready to go for the warm summer months. Preparing your system early prevents midsummer breakdowns.
Routine maintenance also helps extend the lifespan of your air conditioner and keep it operating efficiently. Stay comfortable throughout the warmer months with a well-maintained AC.
