Your Trusted Local HVAC Company in St. Marks, FL

Living in St. Marks means enjoying the unique beauty of Florida's coast, but it also means relying on a robust and efficient HVAC system to handle the demanding local climate. From the intense, humid heat of summer to the surprisingly brisk winter evenings, your comfort depends on a system that’s up to the challenge. The coastal air, high humidity, and powerful sun present specific challenges that generic HVAC solutions often overlook. That’s where specialized, local expertise becomes essential. We provide comprehensive HVAC services designed specifically for the needs of homes and light commercial properties in St. Marks, ensuring your indoor environment remains a perfect escape, no matter the weather outside.

Comprehensive HVAC Solutions for the St. Marks Climate

Our deep understanding of the local environment informs every service we provide. We recognize that an HVAC system in St. Marks must do more than just cool and heat; it must effectively manage humidity, resist the corrosive effects of salt air, and operate with maximum efficiency to keep energy costs down. We offer a full spectrum of services to keep your system in peak condition.

Air Conditioning Services

When summer temperatures climb, a functioning air conditioner isn't a luxury—it's a necessity. We specialize in all aspects of AC service to ensure you stay cool and comfortable. Our technicians are proficient in diagnosing and repairing all makes and models, addressing common issues like refrigerant leaks, sensor problems, drainage clogs, and electrical failures.

For systems that are outdated, inefficient, or beyond repair, we offer expert AC installation and replacement. We help you select a unit that is properly sized for your space and engineered to withstand our coastal conditions, focusing on models with high SEER ratings and corrosion-resistant components. Regular AC maintenance and seasonal tune-ups are also crucial for prolonging the life of your equipment, improving efficiency, and preventing unexpected breakdowns during the hottest days of the year.

Heating Services

While Florida is known for its heat, the winter months in St. Marks can bring a damp chill that makes a reliable heating system indispensable. We provide complete heating services to keep your property warm and cozy. Our team is equipped to handle repairs on various types of heating systems, including furnaces and heat pumps.

When it's time for a new heating system, we guide you through the options, from high-efficiency electric furnaces to versatile heat pump systems that provide both heating and cooling. A professional installation ensures your system operates safely and effectively. We also offer routine heating maintenance and tune-ups to prepare your system for the cooler season, ensuring it’s ready to perform when you need it most.

Heat Pump Services

Heat pumps are an incredibly popular and efficient choice for the St. Marks climate, offering both powerful cooling and effective heating in a single unit. Their energy-efficient operation makes them a smart investment for year-round comfort. We are experts in heat pump technology, providing specialized installation, repair, and maintenance services. Whether your heat pump is stuck in one mode, making strange noises, or simply not performing as it should, our technicians can diagnose the issue and provide a lasting solution. Regular maintenance is key to preserving the efficiency and dual-function performance of your heat pump.

Ductless Mini-Split HVAC Systems

For homes with no existing ductwork, new additions, or specific zoning needs, ductless mini-split systems offer a flexible and efficient solution. These systems provide targeted heating and cooling to individual rooms or zones, allowing for customized comfort and significant energy savings. We offer professional installation of ductless systems, ensuring optimal placement and performance. Our services also include ductless repair and maintenance to keep your zoned system running smoothly and efficiently.

Enhancing Your Indoor Air Quality in a Coastal Environment

The air you breathe inside your home is just as important as the temperature. In a coastal area like St. Marks, high humidity and airborne allergens can significantly impact your comfort and health. We provide advanced indoor air quality (IAQ) solutions designed to address these specific challenges.

Whole-House Dehumidifiers:

High humidity can make your home feel sticky and warmer than it is, forcing your AC to work overtime. A whole-house dehumidifier integrates with your HVAC system to remove excess moisture from the air, improving comfort, reducing strain on your air conditioner, and inhibiting the growth of mold and mildew.

Air Filtration and Purification:

We offer a range of air cleaning solutions to capture dust, pollen, pet dander, and other airborne contaminants. From high-efficiency media air cleaners to advanced HEPA filtration systems, we can help you find the right solution for your family’s needs. UV air purifiers can also be installed within your ductwork to neutralize viruses, bacteria, and mold spores, providing an extra layer of protection.

Ductwork Services:

Your ductwork is the circulatory system of your HVAC. Leaky or poorly insulated ducts can lead to significant energy loss, poor air quality, and uneven temperatures. We provide thorough duct inspection, sealing, and repair services to ensure your system operates at peak efficiency and delivers clean, conditioned air to every room.

I have nothing but great things to say about this company! From the initial call to trouble shoot our old system to the installation of the new system. Maya was awesome and patient with us and the bank. Stratton, Wilton, and Austin did the removal and install of the systems and they were professional and proficient. I will be recommending this company to everyone and anyone! Thank you for making this less stressful then it needed to be. I'm very grateful for the help and comfort they have given me and my family.

We’ve had issues with our a/c unit freezing up off and on for a month or so. Aden from Keith Key came out and checked our system out. He fixed an issue with the bypass valve and also tuned our fan. Additionally we also replaced our thermostats with new T10’s. He took his time and helped me connect all of them to the WiFi and the app.Aden is very friendly and knowledgeable. I haven’t had an issue with my system since. He was also willing to accept the assistance of our overly helpful shih tzu. Call Keith Key and Aden for any issues with hvac systems, they can get it fixed!

We had a tenant with no heat during the recent 29 degree weather. I called Keith Key Heating and Air before office hours and left my infomation with their answering service. I got a call back from the office promptly at 8:00 a.m. They were able to schedule us for service the same day. The technician arrived at noon, diagnosed the issue and made the repair. The price was quite reasonable. Everyone that we dealt with was friendly, professional and knowledgeable. I would highly recommend them and will be using them again in the future. Thanks Keith Key Heating & Air!!

We've called on Keith Key Heating and Air twice for help. Both times, they responded quickly, and were able to make repairs quickly. The techs we've dealt with have been friendly, reliable, professional and knowledgeable. And they don't dig in your pocket like some have been known to do. I honestly don't know what more we could ask for. A solid 10 of 10, and we highly recommend.

Keith Key regularly services both our personal home and one of our rental properties! They are good about communicating to us about the condition of the units at the rental property which is such a relief! We have had to call them for 2 emergencies and both times the techs appeared happy to be there helping us despite being on the weekend! 10/10 recommend.
