Why does your upstairs always feel hotter than downstairs?

A few common reasons:
• Poor airflow
• Ductwork issues
• Lack of insulation
• Older HVAC systems struggling to keep up
The good news? Most of these problems can be improved with the right setup and maintenance plan.

Feel The Love is one of our favorite times of the year. ❤️

Last year, we had the honor of helping a hardworking single mom in Chickasha who had been struggling for years without reliable heating and air. Between work, school, and raising a family, replacing an HVAC system just wasn’t possible, and that’s exactly why this program matters.

Know someone who could use a break or always gives back to others?
Nominate them. You never know how much of a difference it could make! 👇

Another commercial job completed for Choctaw Nicoma Park!

Commercial ductwork installation. Measured, fitted, and ready to run. Glad to keep another Oklahoma building comfortable.

Have a commercial HVAC project coming up? We'd love to help.

Everyone deserves to feel comfortable in their own home.

For some families, keeping warm in the winter or cool during an Oklahoma summer just isn’t possible right now.
That’s why we’re honored to be part of Lennox Feel The Love. ❤️

This program helps provide a new HVAC system to someone who’s been there for others, even during difficult times of their own.

Know someone like that? Nominate them below.

Some people spend their lives showing up for others. Mark and Sherri Young are those people.
After a difficult season filled with health challenges and their AC going out during the Oklahoma heat, we were honored to surprise them with a brand new Lennox system through the Feel The Love campaign.

Mark and Sherri have spent years serving their students, schools, and community in Marlow, always putting others first. Being able to give back to a family like theirs is what Feel The Love is all about. ❤️
