Pro Tips to Keep Your HVAC System Running at Its Best

A well-maintained HVAC system performs better, saves money, and keeps you comfortable year-round. Here are some expert tips to help you extend the life of your heating and cooling equipment.

  • Seal and Insulate Ducts: Leaky ducts waste energy and can compromise your system’s ability to heat or cool your space evenly. Use high-quality materials like foil tape or mastic sealant for long-lasting results.  
  • Clear Debris Around Outdoor Units: Make sure any leaves, dirt, or debris are removed from around your outdoor units to maintain proper airflow. Check regularly to prevent blockages that could strain your system.  
  • Schedule Regular Maintenance: Biannual tune-ups help catch minor issues before they become costly problems. Our maintenance plans give you exclusive benefits like discounted repairs and priority service. Plus, a well-maintained system lasts longer and performs better.  
  • Upgrade When Needed: If your system is nearing 10–15 years old, upgrading to an energy-efficient model can lower your utility bills and improve indoor comfort. Modern models also come with smart features for better control and convenience.

By following these tips, you can keep your system running smoothly. For expert advice tailored to your system, give us a call and schedule your maintenance service today.

Our A/C stopped working on a Sunday and due to health issues, we needed to find a service company available on a Sunday. I called MJB and left a message on their emergency voice mail. Within 10 minutes Tom Buck called me to hear my description of the symptoms. He was just finishing an appointment in Wichita and would be on his way to my home on the south end of Derby. He arrived within 30 minutes! From start to finish he was the perfect example of what you could ever hope for in an HVAC tech and a human being. His evaluation of our system inside and out was as thorough as I could ever imagine and once he was done with the repair, our system is running as well or better than ever. Well worth the price for the evaluation, parts, and labor. Thank you again Tom for an awesome experience.

Our AC went out during the hottest days of the year, and they were out next day! We have been jerked around by a shoddy home warranty for years. We finally had a chance to pick our own repair people, and MJB came highly recommended. I can see why! I was impressed with the honesty and speed at which they fixed our AC unit!

Our commercial building had a lightening/electrical strike and damaged our 20 ton AC unit. No one could find us a new unit before the end of September. Imagining going all of August and September with no AC in Kansas and working inside near 100 degree temps is less than thrilling. Dale and the team at MJB called around and saved the day. They had us a new unit 5 weeks earlier than other could promise and I now have happy employees. The unit is amazingly quiet, super cold and so much more energy efficient. Thank you for being our super hero!

Thank you very much. We had our 1st warm night in 3weeks. MJB took the time and effort to find the real problem. And the employees were kind and thoughtful and explained things very well. I cannot thank you and all of MJB. Will recommend you highly. Thanks again Marjorie Herman Oxford Kansas
