Prepare Your Home to Meet the Latest State Mandates and Energy Codes

If you're thinking about adding or upgrading your air conditioning this year, there are a few important things to know first. In 2025, Washington is rolling out new rules that change how AC installations work. These state-mandated changes include updated residential energy codes, stricter permitting and inspection requirements, and more accountability for homeowners. It may sound a little overwhelming, but don’t worry, we’re here to help make it all make sense!

In this blog, we’ll break down what these changes mean for you and how to navigate the process with confidence. We’ll also cover the key questions to ask your contractor so you can be sure your new system is up to code and ready to go in Bellevue, WA, and the surrounding areas.

Comparing Central Air vs. Mini-Split AC Installations 

Choosing the right cooling system for your home can feel overwhelming, especially with so many options out there. One of the most common questions we hear from families in Issaquah and surrounding areas is: “Is a mini-split system more efficient than central AC?” 

As your local HVAC experts, our team at Bob’s Heating & Air Conditioning is here to help break it all down. Here’s what each system offers and how to decide which is right for your family.

Take Control of Your Home’s Power and Comfort

We recently added solar services to our list of home comfort services to meet this growing demand​. In this thought piece, we’ll explain why so many of our clients are going solar and how solar can work hand-in-hand with their heating and cooling systems.

At Bob's Heating & Air Conditioning, we've helped countless families in Issaquah and the Eastside improve their indoor comfort and well-being while keeping energy costs in check.

Breathe Easier This Spring

Spring is a season of renewal, but for many households in Bellevue, WA, and the surrounding areas, it also marks the return of seasonal allergies, increased humidity, and airborne irritants!

While opening the windows may bring in a breeze, it can also invite pollen and dust inside. If you want to keep your home’s air fresh and healthy, here are some actionable steps to improve indoor air quality this spring. Keep reading below for our top air quality tips for spring!

Save More Energy with the Right AC Unit 

During Puget Sound spring, we get a nice break from high energy bills. Most days, it’s warm enough to keep the heating off, and we don’t need the AC on yet. 

But once the temperature starts inching into the high 70s, 80s, and 90s, our energy usage starts creeping up as we turn on the air conditioning. If you’re tired of paying high electricity bills every summer, tools like smart thermostats can help you cut back. But sometimes, it’s your AC unit itself that’s wasting more power than necessary. 

At Bob’s Heating, we help homeowners in Issaquah and surrounding areas keep their homes cool while reducing energy costs. One way to spot if your AC is an energy waster is to check its AC Seer rating. If it’s high, great—but if it’s low, contact Bob’s Heating for help picking out a new, highly efficient AC.
