Stay Cool Climate Control

Custom Humidifiers

Dry indoor air can leave your home feeling uncomfortable and your health at risk. Low humidity often leads to itchy skin, irritated sinuses, and static shocks, while also damaging wood floors, furniture, and even musical instruments. It can also strain your heating system, making it harder to maintain warmth during the colder months.

Stay Cool Climate Control installs and services humidifiers that restore balance to your indoor environment. By adding the right amount of moisture, a humidifier improves comfort, supports better breathing, and protects the structure of your home. Our team helps homeowners choose the best system for their needs and ensures it integrates seamlessly with their HVAC equipment. Schedule your humidifier service today with Stay Cool Climate Control and start experiencing fresher, healthier air in every room.

Whole-home humidifiers

Whole-Home Humidifiers vs. Store-Bought Units

Not all humidifiers are created equal, and the type you choose has a big impact on comfort and convenience. While portable models can offer short-term relief, whole-home humidifiers deliver long-term benefits that make a noticeable difference for your household. Here are some key advantages of choosing a whole-home system:

  • Coverage for the Entire House: Portable units only treat one room at a time, while whole-home humidifiers regulate humidity evenly throughout every space.
  • Low Maintenance: Store-bought units require frequent refilling and cleaning, whereas professionally installed systems connect to your water supply and need only seasonal maintenance.
  • Better Air Quality: Whole-home systems are less likely to harbor mold or bacteria compared to portable units that collect standing water.
  • Improved Efficiency: Integrated systems work alongside your HVAC equipment, helping it heat your home more effectively during the winter.
  • Lasting Investment: While portable units wear out quickly, whole-home humidifiers are built to last and add value by protecting your home and furnishings.

Our Humidifier Services

A humidifier only works as well as the installation and care it receives. At Stay Cool Climate Control, we provide complete humidifier services that keep your system reliable and your home comfortable. Our technicians focus on selecting the right model, setting it up correctly, and maintaining it for long-term performance. Each service is tailored to your home’s specific needs so you can enjoy healthier air without unnecessary hassle. Here’s how we help homeowners get the most out of their humidifiers:

Humidifier Installation

We evaluate your home’s size, HVAC system, and comfort needs before recommending the best humidifier. Proper installation ensures the unit distributes moisture evenly and integrates seamlessly with your heating system. This approach delivers consistent humidity control that supports health and comfort year-round.

Humidifier Replacement

If your current humidifier is outdated or no longer effective, we replace it with a modern system designed for efficiency. Newer models use advanced technology to provide precise moisture control and reduce maintenance needs. Our team handles removal, installation, and testing to ensure a smooth upgrade.

Humidifier Maintenance

Routine maintenance keeps your humidifier performing properly and prevents issues like mineral buildup or clogged lines. We clean and inspect the system, adjust settings, and check connections to ensure reliability. Ongoing service extends the lifespan of your humidifier and protects your HVAC equipment.

Humidifier Repair

When problems arise, our technicians quickly diagnose and repair your humidifier to restore performance. We address issues such as leaks, electrical malfunctions, or poor moisture output with lasting solutions. Timely repair saves you from bigger breakdowns and keeps your home comfortable.

Whole-Home Integration

Humidifiers work best as part of a complete indoor air quality strategy. We can integrate your system with air filters, dehumidifiers, or UV air sanitizers for maximum comfort. This ensures your home’s air is balanced, healthy, and protected throughout the year.

Dalton came out for our annual furnace maintenance and did amazing!

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.

I had Stay Cool come out for my furnace that quit working while I had just had surgery. Cindy was able to get someone out right away, I had signed up for the membership club that saved me on my repairs, and felt very confident in the technician. He made me feel at ease and comfortable in my decision . Very friendly company that does the job right the first time!

Nathan and Trey came out to do an installation on the exterior, but stuck around to help test my system and give guidance on improving house heating. We found an issue with a fan not being connected to an exhaust pipe and they went out, got materials, and came back and fixed it that day!
