Has your air conditioner stopped cooling? When your AC system suddenly stops cooling in the hot and humid Milton, FL, climate, panic can set in quickly. Don’t sweat it, though. We’ll walk you through why this happens, what to check and when to call in trusted professionals like Lunsford Air Conditioning & Heating to restore comfort to your home.
Why Has My Air Conditioner Stopped Cooling?
Air conditioners are complex systems, and when they stop cooling, it often signals an underlying issue. According to the U.S. Department of Energy, heating and cooling account for approximately 48% of the average home’s energy use, so efficiency is crucial. Common culprits include low refrigerant levels, clogged filters or electrical malfunctions. Recognizing that a breakdown is often a symptom, not the cause, helps homeowners make informed decisions rather than quick fixes that fail long-term.
Check Your Thermostat First
Before assuming the worst, verify your thermostat settings. A surprising number of “AC emergencies” stem from accidental changes in temperature settings or switching the system to “fan” instead of “cool.” A dead battery can also stop communication between the thermostat and the air conditioner. Think of it as the quarterback of your AC system. If it isn’t calling the right plays, the rest of the team can’t perform.
Inspect and Replace Dirty Filters
A dirty air filter is one of the most common reasons an AC system stops cooling effectively. When filters clog, airflow becomes restricted, causing the AC system to overwork and underperform. This can even lead to frozen coils, which block cooling altogether. Experts recommend checking filters monthly and replacing them at least every three months. In humid Milton, FL, frequent air conditioner replacements may be even more crucial to prevent airflow issues.
Look for Frozen or Dirty Coils
If your air conditioner has stopped cooling, check for ice buildup on the evaporator coil or dirt accumulation on the condenser coil. Frozen coils reduce heat exchange, leaving you with lukewarm air. Dirty coils force the system to consume more energy to maintain temperatures. According to ENERGY STAR, clean coils can improve system efficiency by up to 15%. That’s not only better comfort but also lower energy bills.
Identify Electrical or Power Issues
Sometimes, the problem is as simple as a tripped breaker or blown fuse. Outdoor units rely on a consistent power supply to operate the compressor and fan motors. A quick reset of your electrical panel may restore cooling. However, frequent power interruptions often signal a deeper electrical issue that requires professional attention. Ignoring this can put your AC system and your safety at risk.
Recognize When Refrigerant Is Low
Low refrigerant is another leading cause of cooling failures. When refrigerant leaks occur, your system loses its ability to effectively absorb and transfer heat. Not only does this reduce comfort, but it also strains the compressor, often leading to costly air conditioning repairs. EPA studies show that refrigerant leaks contribute significantly to environmental concerns, so addressing them quickly is both a personal and global responsibility.
Take Preventive Maintenance Seriously
Preventive maintenance is the best way to keep your AC system cooling consistently. Consider the following six steps to keep your system running strong year-round:
- Schedule professional tuneups at least twice a year.
- Clean or replace filters regularly.
- Keep outdoor units free of debris and vegetation.
- Inspect ductwork for leaks or blockages.
- Check thermostat accuracy and settings.
- Ensure proper drainage from condensate lines.
These simple measures can extend the life of your AC system, improve efficiency and reduce surprise breakdowns, keeping your home cool and your wallet intact.
