There are a few common reasons your AC might not be cooling your home properly here in Las Vegas. The most likely culprits are a dirty or clogged air filter, low refrigerant, or a failing compressor. With our summers regularly hitting 110°F+, your system is working harder than most units in the country — so even a small issue gets magnified fast. The best thing you can do is get a tech out to take a look before it turns into a full breakdown in the middle of July.

If your AC is running but pushing out warm air, it usually comes down to one of three things — low refrigerant levels, a dirty condenser coil, or a compressor that's starting to fail. In Las Vegas, condenser coils get caked with dust and debris pretty quickly given our dry, windy conditions, which restricts airflow and kills efficiency. Don't ignore warm air coming from your vents — in this heat, it can go from uncomfortable to dangerous in a matter of hours.

When your AC runs constantly but never actually hits the temperature you set, it's usually a sign that the system is undersized for your home, low on refrigerant, or dealing with duct leaks losing cold air before it even reaches your rooms. Las Vegas homes also take on a ton of radiant heat through the roof and windows, which puts extra demand on your system. If your unit is more than 10 years old and struggling to keep up during peak summer, it may be time for a capacity evaluation.

Many technicians offer same-day or emergency service.

If it’s blowing warm air or making noise, it’s best to have it checked.
