Our technicians perform thorough inspections, cleanings, and adjustments to maximize efficiency, improve indoor comfort, and extend the life of your unit. With professional care and a customer-first approach, we make it easy to stay cool, lower energy costs, and prevent breakdowns before they happen.

Why Is AC Maintenance So Important?

Routine AC maintenance is one of the most effective ways to protect your cooling system and your comfort. Air conditioners that receive seasonal tune-ups operate more efficiently, which helps reduce monthly energy bills and prevents unnecessary strain on the equipment. Maintenance also allows technicians to spot small issues before they turn into major breakdowns, saving you from costly emergency repairs. Clean filters, coils, and refrigerant checks ensure your system delivers strong airflow and reliable cooling throughout the summer. With professional air conditioner maintenance from Stay Cool Climate Control, you’ll enjoy greater efficiency, improved indoor air quality, and a longer system lifespan.

AC Maintenance Services We Provide

Stay Cool Climate Control offers comprehensive AC maintenance services to keep your system running efficiently and reliably all summer long. From seasonal tune-ups to preventative inspections, our technicians provide detailed care that protects your investment and improves comfort. Here’s what our AC maintenance includes:

Seasonal AC Tune-Ups

Our AC tune-up services are designed to prepare your cooling system for the hottest months of the year. We inspect all major components, clean filters and coils, and make necessary adjustments to ensure peak performance. Regular tune-ups help reduce energy usage, lower utility bills, and prevent mid-season breakdowns.

Preventative AC Inspections

Thorough AC inspections allow us to catch small problems before they become costly repairs. Our technicians check refrigerant levels, electrical connections, airflow, and thermostat calibration to confirm everything is working properly. With routine inspections, your system will run more efficiently and last longer.

Air Conditioner Cleaning

Dust and dirt buildup can restrict airflow and reduce efficiency, which is why air conditioner cleaning is a vital part of AC maintenance. We clean coils, filters, and other components to restore proper performance and improve indoor air quality. A clean system cools your home faster and runs with less strain.

Performance Testing and Adjustments

Every AC maintenance service includes a full system test to ensure your unit is cooling effectively. We fine-tune settings, test safety controls, and verify that airflow is balanced throughout your home. These adjustments help prevent unexpected issues and keep your system reliable when you need it most.

Travis , the technician, came out in very polite and professional and identified 2 problems I was experiencing with my furnace. The last few days have been very chilly. He stated what was needed and the price it would involve. With recommendations to plan on if other problems arise. He had to gather equipment needed to get the repair done he was quick and fastidious in his service and informed me when it was completed. Was very happy with the results. My furnace is running again and I’m warming back up. Thank you Stay Cool HVAC for you service.

Their quote was spot on, they showed up when they said they would. Great experience. Travis was also super helpful in navigating a new furnace. We will be using them again when our other furnace finally dies. Thank you!

On Jan 16, 2026 I called Stay Cool Climate Control to get a quote on replacing our old HVAC because the furnace was showing signs of imminent failure. I called the office in the morning, and Jeremy was able to come that afternoon. Jeremy looked at the old system and offered us multiple replacement choices. A few days later, after checking with 2 other companies, we concluded that Stay Cool was the best choice for us in terms of cost, efficiency, and equipment quality. We are not disappointed. Installation was scheduled for the following Tuesday. Brandon, Dalton, and Trey arrived on time early that morning, and after seeing the old system began removing it. Even though the outside temperature was in the teens and there was snow on the ground they worked tirelessly all day. By late that afternoon we had a new, highly efficient HVAC system up and running. Our thanks also go to Carter, who has answered many questions and was able to make the quick schedule possible.

HIGHLY Recommend. Our furnace quit right as a winter storm rolled in, and they sent someone out within an hour! Dalton figured out our issue and got our unit to work for just a bit longer until our replacement could be scheduled. Jake and Skylar handled our replacement. The office will send names and pictures of who is coming to your home, which made me feel very safe. Every person we encountered on the phone or in person was professional, friendly, and knew what they were doing. Pricing was fair and transparent, and they helped us get financing. Never felt rushed or pressured. A+ communication.

On time arrival to service my furnace for the winter. Travis was very courteous. He carefully reviewed his findings and answered all of my questions. As a realtor and homeowner, I strongly suggest that your HVAC system be checked, serviced and cleaned twice yearly. Use a professional like Stay Cool Climate Control.
