What Causes an Air Conditioner to Freeze Up?

When your AC unit freezes up, it can be both inconvenient and expensive. The most common reason for this problem is lack of airflow, generally caused by a dirty air filter. Without the free flow of warm air through the AC and over the evaporator coils, these coils can become cold, ultimately freezing and icing over. If a dirty filter is the cause, then replacing it will help solve the problem. However, in some cases, an AC system freezing up can also be linked to low refrigerant levels, damaged ductwork, a malfunctioning blower fan or motor, or a clogged condensate drain—in which case you’ll need to contact our Alexandria AC repair pros to get your system running again.

While an air conditioner freezing up is a common indication of a problem with your system, it is not the only sign you should watch out for that could point to a repair being needed.

What Are the Signs Your AC Needs Repair?

• The system is blowing warm air
• You hear unusual screeching, whistling, or banging noises when the AC is running
• The air quality and humidity levels in your home have changed
• You notice unpleasant odors coming from the air conditioner
• The system has developed a leak
• You find that the temperature fluctuates throughout the home

Why Does My Furnace Keep Turning Off?

While furnaces are an integral part of your home’s comfort during the cold winter months, they can unexpectedly shut off without warning. The reasons why this happens can vary, but some of the most common culprits include a clogged air filter, a faulty thermostat, blocked vents, a damaged motor, or a dirty flame sensor. If your furnace is frequently turning on and then off in quick bursts, then you might be dealing with short cycling, which is often the result of an incorrectly sized furnace, an overheated system, or some of the same issues detailed above.

However, a furnace that keeps turning off or short cycling is not the only potential problem you could face with your heating system. 

Common Furnace Problems:

• Worn blower belt and bearings
• Cracked or damaged heat exchanger
• Faulty limit switch
• Malfunctioning pilot light or ignition 
• Damaged capacitor
• Neglected maintenance
• General wear-and-tear

If you are experiencing any of the above problems, you should reach out to the qualified Alexandria furnace repair pros at Air Treatment Heating & Cooling. We can help identify and resolve these issues before they become more severe, resulting in further damage.

The Benefits of Timely HVAC Replacement in Alexandria

Many homeowners wait until their heating or cooling system finally breaks down before considering a full replacement. However, investing in timely HVAC replacement can provide a range of advantages for your comfort and budget, especially for those living in Alexandria with our hot summers and chilly winters. Waiting too long can mean higher utility bills, reduced air quality, and growing repair costs, so it’s wise to understand the indicators that it’s time for an upgrade.

Replacing older equipment with new, energy-efficient systems can lower your monthly costs and help maintain a more consistent indoor temperature, even as weather fluctuates from season to season. Modern HVAC units are designed to meet both Energy Star recommendations and local Alexandria building code requirements, supporting environmentally friendly homes and compliance with efficiency standards. Plus, newer systems often come with advanced features like programmable thermostats, improved filtration, and quieter operation to enhance your daily experience at home.

When scheduling HVAC replacement Alexandria residents should consider not only the age of their current system but also the potential savings over time. Factors like improved energy efficiency, better humidity control, and fewer service calls all add up, making replacement a practical long-term investment for many families in the Alexandria area. Our team is ready to help you compare available models, answer questions about the installation process, and explain any city permitting needs to ensure a smooth upgrade.

How to Know If You Need a New System

If you’re unsure whether it’s time to replace your HVAC system, consider these important signs:

• Rising energy bills without changes in usage, which can signal declining efficiency
• Frequent repairs or increasing system downtime, even after recent service
• Unusual noises or odors coming from your equipment while running
• Uneven temperatures or humidity levels throughout your Alexandria home
