AC Not Cooling? We Find the Real Cause.
Blowing warm air, weak airflow, or frozen into a block of ice? A West Valley home without cooling in summer is not something to wait on. We diagnose the actual failure the same day and quote the repair upfront, before we touch anything.

Common Reasons an AC Stops Cooling
Low refrigerant from a leak
The system loses its ability to absorb heat, so it runs constantly but never cools. We find and fix the leak, not just recharge it.
Failed capacitor or contactor
A common, affordable failure that stops the compressor or fan from starting on a hot afternoon.
Frozen evaporator coil
Usually caused by a dirty filter, blocked airflow, or low refrigerant. The coil turns to ice and airflow drops off.
Dirty condenser coil
Caked with monsoon dust, the outdoor unit cannot shed heat, so cooling fades in the worst afternoon heat.
Tripped breaker or bad wiring
The outdoor unit loses power while the indoor fan keeps running, so you feel air movement but no cooling.
Failing compressor
The heart of the system. When it goes, we give you an honest repair-or-replace answer on the same visit.

When to Call Us Right Away
If the basics do not fix it, or the house is climbing past a safe temperature, call us. Running a system that is frozen or low on refrigerant can turn a small repair into a compressor replacement, so it is worth getting a technician out quickly.

AC Not Cooling FAQs
Why is my AC running but blowing warm air?
The most common causes are low refrigerant from a leak, a failed capacitor or contactor, a frozen evaporator coil, a dirty condenser, or a tripped breaker on the outdoor unit. When the outdoor compressor is not running but the indoor fan is, you get air movement without cooling. We diagnose the actual cause on site and quote the repair before we start.
What can I check myself before calling?
A few quick things are safe to check: make sure the thermostat is set to cool and below room temperature, replace a clogged air filter, confirm the breakers for both the indoor and outdoor units are on, and check that the outdoor unit is not iced over or buried in debris. If it is frozen, turn the system to fan-only to let it thaw. If none of that fixes it, give us a call.
My AC froze into a block of ice. What happened?
A frozen evaporator coil usually comes from restricted airflow (a dirty filter or blocked return) or low refrigerant from a leak. Running a frozen system can damage the compressor, so switch it to fan-only to thaw the ice, then call us. We find the underlying cause rather than just recharging refrigerant into a system that is leaking.
How fast can you come out when my AC is not cooling?
We offer same-day service on most no-cool calls across the West Valley and target a two-hour response on true summer emergencies, with no overtime markup for evenings or weekends. Our trucks carry common parts, so many repairs are finished on the first visit.
Is it worth repairing, or should I replace the system?
If the system is under about 12 years old and the repair costs less than roughly a third to half of a replacement, repair is usually the right call. If it is older, on phased-out R-22 refrigerant, or failing repeatedly, we give you an honest replacement estimate on the same visit. Because no one here works on commission, that recommendation is based on your equipment, not a sales target.
