“Honest, reliable, customer centered service. Had a complicated situation and they were the only HVAC company that would do the leg work to help me. They stand by their workmanship and care about their customers. It's hard to find this type of genuine commitment and service integrity.” - Tim L.

The best compliment we receive isn't "you fixed it."

It's hearing things like:
"You showed up when you said you would."
"You explained everything without trying to sell me something I didn't need."
"Your technician treated my home with respect."

We believe great HVAC service is about more than heating and cooling. It's about earning trust.

Whether we're helping a family stay comfortable at home or keeping a local business up and running, our goal is always the same: honest recommendations, quality workmanship, and service you can count on.

Thank you to every homeowner and business owner who continues to trust Cornett HVAC. We appreciate the opportunity to serve our community every day.

“Absolute Professionals – Highly Recommend!
I cannot say enough good things about Cornett Heating & Cooling. I reached out to them for service and was incredibly impressed by how prompt and courteous they were right from the start…

What really stood out to me was their honesty. Instead of trying to push unnecessary parts or high-pressure sales tactics, they gave me a straight-shooting, honest assessment of my system. It is rare to find a company with this level of integrity and professionalism.

Your air conditioner works hardest when you need it most.
August is often the toughest month on HVAC systems. After running nearly nonstop all summer, even a well-maintained unit can start showing signs that it needs attention.

Keep an eye out for:

✔️ Warm air coming from your vents
✔️ Rooms that won't cool evenly
✔️ Higher-than-normal energy bills
✔️ Strange noises or odors
✔️ Your system running constantly without reaching the set temperature

Addressing small issues now can help prevent a much bigger (and more expensive) repair down the road.

If something doesn't seem right, don't wait until your system stops working on the hottest day of the year.

We're just a phone call away.

💡 HVAC Pro Tip: Keep Interior Doors Open

Did you know that closing too many interior doors in your home can affect your HVAC system's airflow?

Your heating and cooling system is designed to move air throughout the entire house. When doors stay closed for extended periods, it can create pressure imbalances that make some rooms feel too warm, too cold, or cause your system to work harder than necessary.

For the best comfort and efficiency, try keeping interior doors open whenever possible—especially in rooms with supply vents.

A small change can make a big difference in your home's overall comfort.
