Ever feel lost in the alphabet soup of HVAC terminology? Don’t worry, we’re here to break it down! Today, we’re tackling SEER ratings in HVAC—a crucial factor in understanding the energy efficiency of your air conditioner or heat pump. At TemperaturePro Austin, we believe in empowering homeowners with knowledge, so let’s dive in!

What Does SEER Mean in HVAC?

SEER stands for Seasonal Energy Efficiency Ratio. In simple terms, it’s a measure of how efficiently your cooling system uses energy to keep your home comfortable during those hot Texas summers.

Think of it like your car’s fuel efficiency or miles per gallon (MPG). A higher MPG means you can travel further on a gallon of gas. Similarly, a higher SEER rating means your AC uses less energy to provide the same amount of cooling, leading to lower energy bills.

How is SEER calculated? It’s the ratio of the cooling output (measured in BTUs or British Thermal Units) to the energy input (measured in watt-hours). So, a higher BTU output with lower energy consumption results in a higher SEER rating.

HVAC SEER Ratings: What’s a Good Number?

SEER ratings for residential air conditioners typically range from 13 to 25 or higher. But what’s considered a “good” SEER rating for your Austin home?

The Department of Energy (DOE) sets minimum SEER standards for different regions. In the South, including Austin, the minimum requirement for new AC units is 14 SEER or 14.3 SEER2.

Choosing the right SEER rating depends on your budget and long-term energy savings goals. While higher SEER units generally cost more upfront, they can significantly reduce your energy bills over time (and they’re better for the environment).

SEER2 vs SEER in HVAC

This chart provides a quick and easy comparison of the key differences between SEER and SEER2, helping homeowners understand the recent changes in HVAC efficiency ratings.

Key takeaway: Although SEER2 ratings are numerically lower than SEER ratings, they actually represent higher efficiency levels due to the updated and more stringent testing procedures.

Example: A 14 SEER2 unit is more efficient than a 14 SEER unit.

Here’s a more specific estimate of SEER2 vs SEER ratings in HVAC:

A leaking air conditioner is not only an inconvenience but it can lead to water damage and mold growth in your home. Not only is it messy, but it can also indicate a serious problem with your HVAC system. In this blog post, we’ll dive into why this happens and how you can address it, potentially saving yourself a costly repair bill.

Understanding the Basics: How Does an AC Work?

Before we dive into the causes, it’s helpful to understand the basic operation of your air conditioner. Your AC unit works by removing heat and humidity from the air inside your home. As the warm air passes over the evaporator coils, moisture in the air condenses and collects on the coils. This condensed water is then channeled away from the unit through a drain line. If any part of this process is disrupted, you might end up with a leaking AC.

Common Causes of AC Leaks

Clogged or Blocked Drain Line

The Problem: The most common cause of AC leaks is a clogged or blocked drain line. Over time, dirt, dust, algae, and other debris can accumulate in the drain line, preventing the water from flowing freely. This can lead to water backing up and overflowing from the unit.

The Solution: Regular maintenance is key to preventing clogs. You can try clearing minor clogs yourself using a wet/dry vacuum or a specialized drain line cleaning solution. For stubborn clogs or if you’re uncomfortable tackling this yourself, it’s best to call in a professional HVAC technician like TemperaturePro Austin.

Frozen Evaporator Coils

The Problem: If the evaporator coils freeze up, the ice will eventually melt and cause water to leak from the unit. Several factors can contribute to frozen coils, including low refrigerant levels, dirty air filters, or restricted airflow.

The Solution: If you suspect frozen coils, turn off your AC immediately and call a professional HVAC technician. They can diagnose the underlying cause and safely thaw the coils. It’s crucial to address this issue promptly to prevent damage to the compressor.

Damaged or Cracked Drain Pan

The Problem: The drain pan sits beneath the evaporator coils and collects the condensed water before it’s channeled away. If the drain pan is cracked or damaged, water can leak out.

The Solution: A damaged drain pan needs to be replaced. While a minor crack might be temporarily patched, it’s generally recommended to replace the entire pan to ensure proper drainage.

Condensation Pump Issues

The Problem: If your AC unit is located in an attic, it might have a condensation pump to help move the water upward and out of the unit. If the pump malfunctions, water can back up and leak.

The Solution: Check the condensation pump for any signs of damage or blockage. If you’re unable to resolve the issue, call an HVAC professional to repair or replace the pump.

Incorrect Installation or Improper Maintenance:

The Problem: If your AC unit wasn’t installed correctly or hasn’t been properly maintained, it’s more likely to develop leaks. For example, an improperly leveled unit can cause water to pool in one area and overflow.

The Solution: If you suspect installation or maintenance issues, schedule a professional inspection to ensure your system is operating correctly.

Preventing AC Leaks

• Schedule Regular Maintenance: The best way to prevent AC leaks is to schedule regular maintenance with a qualified HVAC technician. They can clean the drain line, check refrigerant levels, inspect the coils, and identify any potential issues before they cause leaks.
• Change Air Filters Regularly: Dirty air filters restrict airflow and can contribute to frozen coils. Change your filters every 1-3 months, or more frequently if you have pets or allergies.
• Keep the Area Around Your Unit Clear: Make sure there’s adequate space around your outdoor unit for proper airflow. Remove any debris, leaves, or vegetation that could obstruct the unit.

An AC compressor shutting off after 2-3 minutes can be due to several reasons including overheating, electrical issues, refrigerant problems, a faulty compressor, thermostat issues, a clogged filter, or an oversized unit.

Overheating

When the compressor overheats, it can shut down to prevent damage, which is a safety feature designed to protect the unit from further harm. Several factors can contribute to overheating:

Dirty Condenser Coils

Condenser coils release the heat absorbed from your home to the outside. When these coils become dirty or covered with debris, they cannot effectively release heat, causing the compressor to work harder and overheat

Blocked or Restricted Airflow

Proper airflow is crucial for the efficient operation of your AC system. When airflow is restricted due to blocked vents, closed registers, or a dirty air filter, the system cannot circulate air properly. This restriction forces the compressor to run longer and harder, leading to overheating. 

Low Refrigerant Levels

Low refrigerant levels can cause the compressor to overheat because it has to work harder to cool your home. This can be due to a refrigerant leak or an undercharged system.

Electrical Issues

Electrical problems can cause the compressor to short cycle, resulting in the system turning on and off rapidly. This can lead to inefficiency, increased wear and tear, and higher energy bills.

Faulty Thermostat

A malfunctioning thermostat can send incorrect signals to the AC system, causing the compressor to turn on and off unexpectedly. Calibration issues, dead batteries, or placement in an area that doesn’t accurately reflect the home’s temperature can all contribute to short cycling.

Loose or Damaged Wiring

Loose or damaged electrical wiring can disrupt the power supply to the compressor, leading to intermittent operation. Over time, vibrations and regular use can cause wires to become loose, frayed, or disconnected, necessitating regular inspections to ensure all connections are secure.

Malfunctioning Capacitors

Capacitors provide the necessary voltage to start and run the compressor. A failing capacitor can result in the compressor struggling to start or stay running, causing short cycling. Capacitors can degrade over time or fail due to power surges, requiring professional replacement to restore proper function.

Faulty Compressor

A faulty compressor can significantly impact the performance of your AC system, often leading to short cycling or complete system failure. The compressor is the heart of the air conditioning unit, responsible for circulating refrigerant and maintaining the cooling cycle.

Age-Related Wear and Tear

Over time, compressors can degrade due to regular use. As they age, components can wear out, seals can deteriorate, and internal parts may break down. An older compressor may struggle to maintain pressure, resulting in inefficient cooling and frequent shutdowns.

Your AC’s condenser coils, located in the outdoor unit, are responsible for dissipating the heat absorbed from inside your home. If these coils become dirty or blocked by debris, they can’t release the heat efficiently, causing your AC to blow hot air. Regular maintenance, including cleaning the condenser coils, is key to preventing this issue.

Electrical Issues: Disrupting the System

Sometimes, the cause of your AC blowing hot air could be an electrical problem, such as a tripped breaker or faulty wiring. These issues can prevent your AC unit from running properly, leading to a lack of cool air. If you suspect an electrical issue, it’s crucial to turn off the system and contact a professional to avoid further damage or safety hazards.

Frozen Evaporator Coil: A Hidden Culprit

An evaporator coil that’s frozen over can also be the reason your AC is blowing hot air. This problem usually occurs due to restricted airflow—often caused by a dirty filter—or low refrigerant levels. When the coil freezes, it prevents the system from absorbing heat from your home, leading to warm air blowing through your vents. If you notice ice buildup, turn off your AC and let it thaw, then call TemperaturePro Austin for a thorough inspection.

Ductwork Issues: Leaks or Damage

Leaky or damaged ductwork can cause cool air to escape before it reaches your living space, leaving you with warm air instead. Duct leaks not only reduce cooling efficiency but can also increase your energy bills. Our experienced technicians at TemperaturePro Austin can inspect your ductwork and make necessary repairs to ensure your cool air stays where it belongs.

Compressor Failure: A Major Malfunction

The compressor is the heart of your AC system, responsible for circulating refrigerant between the indoor and outdoor units. If the compressor fails, your system won’t be able to cool the air effectively, resulting in hot air. Compressor issues are complex and often require professional repair or replacement.
