🎉 Retirement Announcement: Craig Flenniken 🎉
After more than 30 years in the heating and cooling industry—and nearly three amazing years with us at Dubson Heating, Air Conditioning & Refrigeration—our beloved Lead Service Technician, Craig Flenniken, is officially retiring.
Craig joined our team in September 2022, bringing not only unmatched technical expertise, but also a spirit of kindness, dedication, and professionalism that quickly earned the admiration of both his customers and his colleagues.
💬 Whether he was solving the toughest HVAC issues or simply brightening a job site with his calm, friendly presence, Craig made a lasting impact — and his retirement is hitting all of us here at Dubson Heating a little harder than we expected.
Please join us in wishing Craig the happiest of retirements! You've earned every bit of it, Craig—and we’re better for having worked alongside you. 🛠️❤️

🥵 Is your A/C blowing warm air? You might be low on refrigerant — and that’s a big deal.
Here’s what happens when refrigerant is low:
🔧 Your A/C has to work harder to cool your home
❄️ You’ll notice less cold air or even just room-temperature air
💸 Your energy bills go up while your comfort goes down
🧊 Ice can build up on the coils (yes, even in spring and summer!)
⚠️ And eventually, it can damage your compressor — the heart of your A/C
🚫 Refrigerant doesn’t just "run out" — if it’s low, there’s likely a leak.
📞 Don’t ignore the signs. A quick inspection now can save you from a costly repair later!
