Why Is My AC Running But Not Cooling?
If your AC is running but not cooling, there could be several reasons behind it. Some issues are simple fixes, while others require a professional repair. Understanding these causes will help you determine your next steps.
Common reasons your AC isn’t cooling include:
- A dirty air filter restricting airflow
- Low refrigerant levels due to a leak
- A malfunctioning compressor affecting cooling performance
- Frozen evaporator coils, often caused by restricted airflow
- Thermostat settings that are incorrect or unresponsive
- Outdoor unit obstructions blocking airflow
If basic troubleshooting doesn’t resolve the issue, it’s best to schedule a professional inspection. Continuing to run your AC with an underlying problem can lead to more damage and increased repair costs.
What Is The Most Common AC Repair?
The most frequent AC repairs include refrigerant leaks that cause the system to lose cooling power, dirty air filters that restrict airflow, capacitor or contactor failures that prevent the system from turning on properly and thermostat malfunctions that affect temperature control.
Regular tune-ups can help prevent many of these common repairs, ensuring your AC runs efficiently throughout the year. If you’re experiencing cooling issues, Mission AC can diagnose the problem and get your system back in top shape.
Who Do You Call When Your AC Is Not Working?
When your AC stops working, your best bet is to call a licensed HVAC professional who can diagnose and fix the issue efficiently. While some problems — like a tripped breaker or clogged air filter — can be checked on your own, more complex issues, such as refrigerant leaks, electrical failures or compressor malfunctions, require expert attention.
A professional has the tools and knowledge to pinpoint the problem and restore your system’s performance. At Mission AC, our team is ready to help with reliable AC repairs to keep your home cool and comfortable.
What Is The First Thing To Check When The AC Stops Working?
Before calling for repairs, check your thermostat settings to ensure they are set correctly. Then, inspect the circuit breaker to see if it has tripped. A clogged air filter can also prevent airflow, so replacing a dirty filter might help. If these don’t solve the issue, it’s time to call an HVAC professional.
What Is The Life Expectancy Of A Heat Pump?
A well-maintained heat pump typically lasts close to 15 years. In Houston’s climate, where heat pumps work year-round, regular maintenance is essential to maximizing their lifespan. Scheduling tune-ups and keeping the system clean can help extend its longevity.
What Is The AC Installation Process?
The AC installation process starts with selecting the right system for your home. Once the correct unit is picked out, the installation includes:
- Removing the old unit (if applicable)
- Installing the new indoor and outdoor components
- Connecting refrigerant lines, electrical wiring and ductwork
- Testing the system for efficiency and proper operation
Our team is here to guide you through the process. If you have any questions during your service, don’t hesitate to ask!
How Long Does AC Installation Usually Take?
The time it takes to install a new AC system depends on several factors, but most standard installations are completed within four to eight hours.
If the job involves replacing an existing unit with a similar model, the process is typically quicker. However, if modifications are needed — such as ductwork adjustments, electrical upgrades or installing a completely new system — the installation can take longer. A professional HVAC technician will assess your home’s setup beforehand to provide a more accurate timeline.
How Long Do AC Units Last In Houston?
Due to Houston’s hot and humid climate, AC units will typically last between 10 to 15 years with proper maintenance. The high heat and constant usage can shorten a system’s lifespan, but regular tune-ups, filter changes and proper care can help it last longer.
Are Mini Splits Recommended In Houston?
Mini-split systems can make a good choice for Houston homes, especially for room additions, converted garages and spaces without existing ductwork. They provide efficient cooling, customizable temperature control and lower energy consumption compared to traditional central AC systems.
Are Heat Pumps Recommended In Houston?
Heat pumps can make for an efficient option for Houston’s mild winters and hot summers. They provide both heating and cooling in one system and operate efficiently in moderate temperatures. However, because Houston experiences high humidity and extended summer heat, some homeowners may prefer traditional AC units paired with a furnace for heating.
