When it’s time to upgrade your air conditioner or heat pump, one of the most important numbers to understand is the SEER2 rating. This energy efficiency metric is essential for determining not only how well your system will cool your home, but also how much it will cost you to run.

At Apex Air, we know choosing the right SEER2 rating can make a big difference in Washington homeowners’ monthly utility bills, home comfort and even rebate eligibility. Here’s everything you need to know:

What Does SEER2 Rating Actually Mean?

SEER2 stands for Seasonal Energy Efficiency Ratio 2, and it measures how efficiently an air conditioner or heat pump removes heat from your home during a typical cooling season. The higher the SEER2 rating, the less energy the unit uses to keep your home comfortable.

As of January 2023, SEER2 replaced the original SEER rating system and uses more in-depth testing methods to better reflect real-world performance. It’s similar to how your car might be tested in both city and highway conditions to determine fuel efficiency.

So, What Is a Good SEER2 Rating?

The answer depends on your climate, budget, and how often you use your HVAC system. For Washington State, where summers are generally mild but can occasionally spike, a SEER2 rating of 16–18 is considered a solid middle ground. This range balances cost, efficiency and comfort for most homes in the region.

If you’re aiming for maximum efficiency, units with SEER2 ratings above 20 offer exceptional energy savings, especially when paired with features like variable-speed compressors and smart thermostats.

Here’s a quick breakdown:

• 14 SEER2: Meets minimum federal standards; budget-friendly, but less efficient.
• 16–18 SEER2: Ideal for Washington’s climate; great balance of cost and performance.
• 20+ SEER2: High-efficiency systems with advanced features and the best long-term energy savings.

SEER2 vs. EER2: What’s the Difference?

While SEER2 measures average performance over a season, EER2 (Energy Efficiency Ratio 2) focuses on how well a system performs at peak temperatures — like a 95 F summer day. For Washington homeowners, SEER2 is usually more relevant, but if you frequently experience extreme summer heat, EER2 may also be worth considering.

Benefits of a High SEER2 Rating

1. Lower Energy Bills
   More efficient systems use less electricity to cool your home, leading to monthly savings that add up over time.
2. Improved Indoor Comfort
   Units with higher SEER2 ratings often include variable-speed motors and advanced humidity control for more consistent temperatures.
3. Environmental Impact
   Using less energy means reducing your carbon footprint and contributing to a more sustainable future.
4. Eligibility for Rebates
   To qualify for certain federal tax credits or Washington energy rebates, your system must meet minimum SEER2 thresholds. For example, heat pumps must be at least 16 SEER2, and air conditioners must be 17 SEER2 or higher.

Is a Higher SEER2 Rating Worth the Cost?

The answer depends on your long-term goals. Higher-efficiency systems cost more upfront but often pay for themselves through energy savings over 10 to 15 years. If you plan to stay in your home for a while — or want to boost resale value — investing in a high SEER2 unit is often worth it.

However, if you have a tight budget or rarely use your cooling system, a lower-SEER2 model may be more cost-effective.

Humidity might not be the first thing you think of when it comes to home comfort, but it plays a critical role in how your house feels and how well your body functions. Too much moisture in the air can leave your home feeling stuffy, drive up your energy bills, and contribute to health concerns ranging from allergies to asthma flare-ups. Too little and you could be dealing with dry sinuses, cracked skin and a greater risk of viral infections.

At Apex Air, we understand the unique challenges of the damp Pacific Northwest climate in maintaining balanced indoor air. Let’s take a closer look at why humidity matters, the symptoms of high humidity in home environments, and how HVAC solutions can help restore balance.

What Is High Humidity, and Why Does It Matter Indoors?

Humidity refers to the amount of water vapor in the air. High humidity means the air is holding more moisture than usual, making it feel warmer and heavier. Your body works harder to stay cool in high humidity because sweat doesn’t evaporate effectively. That’s what causes that sticky, overheated feeling. Indoors, excess humidity doesn’t just make you uncomfortable; it alters air quality, encourages mold growth and makes your HVAC system work overtime.

Signs of High Humidity in Home Environments

Recognizing the signs of high humidity can help you address the problem before it leads to structural damage or health issues. Watch for these red flags:

• Condensation on windows and walls
• A musty or damp smell, especially in basements or closets
• Visible mold or mildew
• Warped wood or peeling paint
• Frequent allergy or asthma flare-ups
• Sticky or clammy indoor air
• Increased dust mite activity
• Higher-than-normal energy bills due to AC overuse

These signs of high humidity in home spaces should never be ignored. If you notice one or more, it’s time to consider moisture control strategies.

Health Effects of Poor Indoor Humidity

High humidity doesn’t just impact comfort; it can pose real health risks. Here are some symptoms of high humidity in your home:

• Asthma and COPD – Moist air is harder to breathe and may restrict airways.
• Allergies – Mold and dust mites thrive in humid environments.
• Respiratory infections – Viruses and bacteria spread more easily in poorly balanced indoor air.
• Skin conditions – High or low humidity can cause eczema or dry, cracked skin.
• Heat-related illnesses – When your body can’t cool itself, you’re at greater risk of dehydration, heat exhaustion or even heat stroke.

Humidity can also make medications less effective and strain the heart and kidneys in individuals with preexisting conditions.

How To Manage and Monitor Humidity in Your Home

Indoor humidity levels should ideally stay between 40% and 60%. Here are some ways to monitor and control it:

• Use a Hygrometer: This small device measures indoor humidity and can be found at most hardware stores.
• Install a Whole-Home Dehumidifier: Connected to your HVAC system, it helps keep moisture levels in check across your entire house.
• Schedule HVAC Maintenance: A clean, efficient system drains moisture properly. At Apex Air, we offer seasonal tune-ups that include drainage checks, filter replacement and airflow optimization.
• Ventilate Properly: Make sure bathrooms, kitchens and laundry areas are equipped with exhaust fans that send humid air outside.
• Seal Leaks and Insulate: Prevent outdoor humidity from creeping in through windows, doors and ductwork.
