Stay Cool Climate Control

Specialized Air Filters

Airborne dust, allergens, and pollutants can build up quickly inside your home, leaving the air unhealthy and forcing your HVAC system to work harder. Old or clogged air filters lose their effectiveness, allowing contaminants to circulate and causing energy bills to rise. Over time, neglected filters not only harm your indoor air quality but also put unnecessary strain on your heating and cooling equipment.

Stay Cool Climate Control offers air filters that improve the air you breathe while protecting your HVAC system. From standard replacement filters to high-efficiency options designed to capture fine particles, we provide solutions that make your home cleaner and more comfortable. Our technicians ensure the right filter is selected and properly maintained so you can enjoy reliable airflow and healthier living spaces. Contact Stay Cool Climate Control today to schedule air filter service and start experiencing the difference clean air can make.

Types of Air Filters We Service

Not all air filters are the same, and each type offers unique benefits for your home and HVAC system. Stay Cool Climate Control services a wide range of air filters to ensure your indoor air stays clean and your equipment performs efficiently.

  • Fiberglass Air Filters: These disposable filters are affordable and designed to catch larger particles like dust and lint. They need frequent replacement and offer only basic filtration.
  • Pleated Air Filters: With folded material that increases surface area, pleated filters capture smaller particles such as pollen and pet dander. They last longer than fiberglass filters while improving indoor air quality.
  • HEPA Air Filters: High-Efficiency Particulate Air (HEPA) filters capture up to 99.97% of microscopic particles. They’re excellent for allergy sufferers but may require HVAC adjustments for proper airflow.
  • Electrostatic Air Filters: These filters use an electrostatic charge to attract and trap dust, smoke, and dander. They come in disposable or washable options, making them versatile and effective.
  • Washable Air Filters: Designed for reuse, washable filters can be cleaned and reinstalled instead of replaced. They’re environmentally friendly but require regular maintenance to stay effective.

Our Air Filter Services

Air filters play a critical role in keeping your home comfortable and your HVAC system efficient. Choosing the right filter, installing it correctly, and maintaining it on schedule all contribute to cleaner indoor air and fewer allergens. At Stay Cool Climate Control, we offer professional air filter services designed to protect your equipment and improve the air you breathe. With our team’s support, your system will run smoothly while delivering healthier air throughout your home.

Filter Replacement

We handle timely filter replacement to make sure your HVAC system always has the proper protection. Replacing filters prevents clogs that restrict airflow and allows your system to operate efficiently. Regular replacements also help reduce allergens and contaminants circulating through your home.

Filter Upgrades

For homeowners who need more than basic filtration, we offer upgrades to pleated or HEPA filters. These advanced options capture smaller particles like pollen, dust mites, and pet dander for cleaner indoor air. Upgraded filters not only improve comfort but also support better health for sensitive family members.

System Compatibility Checks

Not all filters work with every HVAC unit, and using the wrong one can reduce airflow or damage the system. Our technicians evaluate your equipment to ensure the filter chosen is the right fit. This process helps your system run efficiently and prevents unnecessary strain.

Routine Maintenance

During scheduled HVAC maintenance, we inspect, clean, and replace filters as needed. This proactive approach keeps your system working smoothly and extends its lifespan. It also ensures your air filters are consistently performing at their best.

Indoor Air Quality Integration

Air filters work best as part of a complete air quality strategy. We can pair them with UV sanitizers, humidifiers, or dehumidifiers for maximum comfort and cleaner air. This integration delivers healthier living conditions and a stronger defense against indoor pollutants.

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.
