What You Need to Know About Heating, Cooling & Airflow

  • 1. Why isn’t my HVAC system heating or cooling my home evenly?

    Uneven heating or cooling is often caused by restricted airflow, poor duct design, or an aging system that’s struggling to keep up. We can perform a full system evaluation—including ductwork inspection and airflow diagnostics—to pinpoint the issue and restore comfort room to room.

  • 2. When should I call a professional for HVAC service?

    Call us if:

    • Your system isn’t heating or cooling properly.
    • Your energy bills have spiked without explanation.
    • You hear unusual noises or smell something off.
    • You need custom ductwork or better airflow.
    • It’s time for seasonal maintenance.
    • You’re planning a remodel or equipment upgrade.

    Even small symptoms can point to larger issues. We’ll give you honest answers and real solutions.

  • 3. What’s the benefit of custom sheet metal ductwork?

    Custom ductwork ensures proper airflow, system efficiency, and consistent comfort throughout your home or building. Poorly designed or undersized ducts can restrict air movement, leading to hot and cold spots, noisy operation, and high utility bills. We design and install duct systems tailored to your space and HVAC equipment.

  • 4. How often should I schedule HVAC maintenance?

    We recommend seasonal maintenance twice a year—once in the spring for your cooling system and once in the fall for your heating system. Regular tune-ups help improve efficiency, extend equipment life, reduce the risk of breakdowns, and ensure safe operation all year long.

Highly recommend Michael Dean!!! Our furnace died on the coldest day of the year. After several quotes, Mr. Dean was the most reasonable and fair. He will not disappoint!! He and his technician were prompt, diligent and very knowledgeable! He’s honest and cleaned his workspace. Everything works extremely well! Call him!!!!

We had Mike for an emergency call on our air conditioner. We could have not been more pleased with his knowledge and honesty. He definitely deserves a five-star plus. He is one of the nicest and competent service people that we have ever had. We recommend him highly. He does great work.

Mike and Wonder were great. They made this old lady a priority since I had an 80 gallon water heater that was leaking badly. They were very efficient and much less expensive than I expected. Dean's Heating and Air Conditioning is the one I'll call the next time I have a plumbing or AC problem.
