What You Are Dealing With

These Problems Will Not Fix Themselves

AC issues get worse, not better. What starts as “a little warm” becomes a full system failure at the worst possible time.

Warm Air Coming From Vents

Your AC is running but the air is warm or room temperature. Could be a refrigerant issue, a compressor problem, or a failed component. It will not resolve on its own.

Weak Airflow

You can barely feel air from the vents even though the system is on. Blocked ducts, failing blower motor, or frozen coil. Your system is working overtime for nothing.

House Won’t Reach Set Temperature

Thermostat says 72. Your house feels like 82. The system runs nonstop but never catches up. This is not normal and it is costing you money every hour.

Upstairs Is an Oven

Main floor feels okay but upstairs is unbearable. Heat rises, but this extreme difference means your system or ductwork cannot handle the load.

Energy Bills Spiking

Your AC is running longer and harder to compensate for whatever is wrong. You are paying premium California electricity rates for a system that is failing to cool.

System Keeps Shutting Off

Short cycling – the system starts, runs briefly, then shuts off. Starts again. Repeats. This is the system protecting itself from damage. It needs professional attention now.

Small AC Issues Become Big Repairs Fast

What Could Be Wrong

Common Reasons Your AC Is Not Cooling

Some are simple fixes. Some are serious. All of them need a professional diagnosis, not guesswork.

Refrigerant Issues

Low refrigerant means your system cannot absorb heat from the air. This is often caused by a leak, not just low levels. Adding refrigerant without finding the leak is throwing money away. A qualified technician pressure-tests the system, finds the leak, repairs it, and recharges to manufacturer specs.

Dirty or Frozen Evaporator Coil

Dust and debris coat the indoor coil over time, insulating it from the air it needs to cool. In severe cases, the coil freezes solid, blocking airflow entirely. Running your system with a frozen coil causes compressor damage. This is a common and preventable failure.

Failed Compressor

The compressor is the heart of your AC. When it fails, nothing cools. Compressor replacement is one of the most expensive AC repairs. In many cases, early diagnosis of other issues prevents compressor failure entirely.

Thermostat Problems

Sometimes the system is fine but the thermostat is misreading, miscalibrated, or failing. If your thermostat says 72 but the house feels much hotter, this is the first thing a technician checks. Quick and inexpensive to fix when caught early.

Ductwork Leaks or Blockages

Your AC could be working perfectly but leaking 20-40% of its cooled air into your attic through damaged ductwork. Common in California homes where ducts run through superheated attic spaces. The system runs overtime, your bills spike, and your house stays hot.

Electrical or Capacitor Failures

Capacitors, contactors, and relays wear out, especially in California heat where systems run extensively. A failed capacitor stops the compressor or fan from starting. You hear a clicking or humming sound but nothing happens. These are quick fixes when diagnosed early.

What Gets Done

Your Matched HVAC Pro Handles All of This

Full System Diagnostics

Comprehensive inspection of your entire AC system. Electrical, mechanical, refrigerant, airflow. Your tech identifies exactly what is wrong before recommending anything.

Refrigerant Leak Repair

Pressure testing, leak detection, repair, and proper recharge to manufacturer specifications. No guesswork, no “just add more freon” shortcuts.

Coil Cleaning & Repair

Evaporator and condenser coil cleaning, defrosting frozen coils, and restoring proper heat exchange. The most common fix for “running but not cooling.”

Electrical Component Repair

Capacitors, contactors, relays, wiring. The small parts that stop everything when they fail. Fast diagnosis, fast repair.

Airflow & Duct Assessment

Is the problem the AC or the ducts? Your pro checks both. Duct leaks in California attics are a hidden cause of cooling failure.

System Replacement Guidance

If repair is not cost-effective, your pro gives you an honest assessment and replacement options. No pressure to decide on the spot.

Pro Tip for California Homeowners
“If your AC is blowing warm air, do not keep running it hoping it fixes itself. A system running without proper refrigerant or with a frozen coil is actively damaging the compressor. Turning it off and calling a professional saves you hundreds – sometimes thousands – compared to waiting.”
Common Questions

AC Not Cooling – FAQs

The most common causes are low refrigerant (often from a leak), a dirty or frozen evaporator coil, a failed compressor, or a thermostat issue. Each requires different repair. A qualified HVAC technician diagnoses the specific cause before recommending a fix.
If the system is running but not reaching the set temperature, the most likely causes are refrigerant issues, duct leaks (extremely common in California attics), an undersized system, or a failing compressor. The system is working but cannot meet demand. This gets worse and more expensive every day you wait.
No. If your AC is not cooling properly, running it continuously can cause further damage, especially to the compressor. If you suspect a frozen coil, turn the system off and let it thaw for a few hours, then call a professional. Running a damaged system is how a repair turns into a replacement.
Renovett matches you with available HVAC professionals in your area. During peak California summer, same-day and next-day appointments are available through our network, though availability varies by area and demand. Call now to check availability for your ZIP code.
It depends entirely on what is wrong. A capacitor replacement might run a few hundred dollars. A refrigerant leak repair costs more. A compressor replacement is significantly more. Your matched professional diagnoses the problem first and gives you a transparent written estimate before any work begins. No surprises.
General rule: if the repair costs more than 50% of a new system, or if your system is over 15 years old and needs a major repair, replacement is usually the smarter investment. Your matched HVAC professional will give you an honest recommendation based on your specific situation. Renovett pros do not pressure you either way.
Heat rises, but extreme differences between floors usually point to duct issues (leaks or imbalance), an undersized system, or poor insulation in the attic. In California homes, attic temperatures can exceed 150 degrees, and ducts running through that space lose enormous amounts of cooling. A professional assessment identifies the cause.
