Why Is Heating Maintenance Important?
Regular heating maintenance is one of the best investments you can make in your home’s comfort and efficiency. Seasonal tune-ups help reduce wear and tear on your equipment, allowing it to run more smoothly and use less energy. By identifying and addressing small issues early, maintenance prevents costly breakdowns and extends the lifespan of your system.
Maintenance also plays an important role in safety and indoor air quality. Clean filters, properly calibrated thermostats, and well-maintained components ensure your heating system operates safely while keeping the air in your home healthier. With professional care from Stay Cool Climate Control, you’ll enjoy peace of mind, lower energy bills, and reliable warmth all winter long.

From detailed tune-ups to preventative inspections, our team ensures every part of your heating system is operating at its best. Here’s what’s included in our services:
Seasonal Heating Tune-Ups
Our heating tune-up services prepare your system for the demands of cold weather. We carefully check all major components, make necessary adjustments, and test safety controls to guarantee reliable performance. Regular tune-ups help reduce energy use and prevent mid-season breakdowns.
Preventative Heating Inspections
A thorough heating inspection allows our technicians to identify worn parts, leaks, or inefficiencies before they lead to costly repairs. We review electrical connections, airflow, and thermostat calibration to confirm your system is working properly. With consistent inspections, your heating unit will last longer and run more efficiently.
System Cleaning and Care
Dust, debris, and buildup can restrict airflow and reduce your system’s efficiency, which is why cleaning is a vital part of heating maintenance. Our technicians clean components like burners, filters, and coils to restore proper airflow and improve indoor air quality. A cleaner system not only performs better but also operates more safely.
Performance Testing and Adjustments
Every heating maintenance service we provide includes testing your system’s overall performance. We ensure the unit heats evenly, operates efficiently, and responds correctly to thermostat settings. These adjustments help you enjoy steady comfort and lower energy costs all season.

Always a great service from these guys. Jacob was out and went through my furnace and cleaned everything up. Very professional and easy to talk to. I’ve had them servicing my hvac for about 6 years now and they have always been able to make things work or work better.

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.

Called 3 companies early in the morning. Stay Cool was able for me to take pics of the area while other companies wanted to come out 3+ days later to look while we had no hot water. Stay Cool was able to come out the same day which was a huge plus for us since we had not had hot water for 2 days already. Their price was also $350 and $700 cheaper than 2 other companies I have had in the past. Travis and Carter showed up on time and walked me through the tearing out and install of the new heater. They were courteous of their wet shoes with slips if they had to go to their truck outside when tearing out the old water heater. Carter, with our older heavy door headed to the garage it doesn't take much to close it. Please be easier in the future. There was an issue with the old water heater being taken up the steps with a dolly that scrapped all the way up the steps in pic 2. I called the main office, they apologized, and they sent Travis back out the next day to repaint. Ill still keep them in mind for future projects. thank you.
