How do I know if my AC needs repair?

Common signs your AC needs repair include: warm air blowing from vents, unusual noises like grinding or squealing, weak airflow, moisture or leaks around the unit, frequent cycling on and off, and unusually high energy bills. If you notice any of these issues, your AC system may need professional attention.

What causes an AC to stop cooling?

An AC may stop cooling due to several reasons: dirty air filters restricting airflow, low refrigerant levels indicating a leak, frozen evaporator coils, faulty compressor, thermostat issues, or blocked condenser unit. In Las Vegas extreme heat, overworked systems and clogged filters are the most common causes.

How often should AC be serviced in Las Vegas?

In Las Vegas climate, AC systems should be serviced at least twice per year - once in spring before the cooling season begins and once in fall. Due to extreme heat and heavy usage during summer months (6+ months of cooling), Las Vegas AC units require more frequent maintenance than typical climates.

What is the average cost of AC repair in Las Vegas?

AC repair costs in Las Vegas typically range from $150-$500 for common repairs like capacitor replacement or refrigerant recharge, $500-$1,500 for compressor issues, and $200-$800 for evaporator coil repairs. Emergency service and weekend calls may cost 20-50% more. Multiple quotes are recommended.

Can I fix my AC myself or do I need a professional?

Simple tasks like changing air filters, cleaning vents, and checking thermostat settings can be done yourself. However, issues involving refrigerant, electrical components, compressor, or internal parts require licensed HVAC professionals due to safety concerns and EPA regulations. DIY repairs on complex issues can void warranties.

Step-by-Step DIY Troubleshooting Guide

Step 1: Reset Your AC System

Turn OFF your thermostat completely
Go to your electrical panel and flip the AC breaker to OFF
Wait 60 seconds (this allows capacitors to fully discharge)
Flip the breaker back ON
Return to thermostat and turn it back on to COOL mode
Set temperature 5°F below current room temperature
Wait 5 minutes to see if outdoor unit starts

Step 2: Inspect Your Air Filter

A severely clogged filter causes 40% of AC shutdowns in Las Vegas due to dust and extreme heat.

Locate your air filter (usually behind return air vent or in furnace)
Remove filter and hold it up to light
If you can't see light through it, it's too dirty
Replace with new filter (MERV 8-11 recommended for Las Vegas dust)
Write the replacement date on the filter

Step 3: Check Outdoor Unit

Go outside to your condenser unit
Clear any debris within 2 feet of the unit
Look for ice buildup on copper lines (sign of frozen coils)
Listen for humming without fan spinning (capacitor failure)
Check if fan blade spins freely when pushed by hand (power OFF!)
