Comprehensive HVAC Solutions for Year-Round Comfort

We offer a full spectrum of heating, ventilation, and air conditioning services to keep your systems running at peak performance.

Air Conditioning Services

In Florida, a functioning air conditioner is essential. We specialize in keeping you cool and comfortable when the temperatures rise. Our AC services include expert diagnostics and repairs for all makes and models. Whether your unit is blowing warm air, making strange noises, or has stopped working entirely, our technicians can quickly identify the problem and implement an effective repair. For older, inefficient systems, we provide professional AC installation and replacement services, helping you select a modern, energy-efficient unit that can significantly lower your utility bills. Regular AC maintenance is crucial for preventing breakdowns and extending the life of your equipment, and our tune-ups are designed to optimize performance for the demanding cooling season.

Heating Services

While Florida is known for its heat, a reliable heating system is vital for comfort during the cooler months. We provide comprehensive heating services to ensure your home stays warm and cozy. Our technicians are skilled in repairing and maintaining all types of heating systems, including electric furnaces and heat pumps. If your system is failing to produce heat, cycling frequently, or experiencing other issues, we can provide a swift and accurate solution. We also offer expert installation of new, high-efficiency heating systems tailored to your property’s specific needs.

Heat Pump Services

Heat pumps are an excellent, energy-efficient choice for Florida homes, providing both heating and cooling in a single unit. Our team is proficient in all aspects of heat pump service. We offer precise installation, thorough maintenance, and dependable repairs to ensure your heat pump operates efficiently throughout the year. From addressing refrigerant leaks to fixing reversing valve issues, we have the expertise to keep your versatile system in top condition.

Ductless Mini-Split Systems

For homes with additions, converted garages, or areas where ductwork is impractical, ductless mini-split systems offer a flexible and efficient solution. These systems provide zoned heating and cooling, allowing you to control the temperature in individual rooms for personalized comfort and energy savings. We provide complete services for ductless systems, including professional installation, maintenance, and repair, helping you achieve targeted comfort exactly where you need it.

Enhancing Your Home with Superior Indoor Air Quality

The air you breathe inside your home is just as important as the temperature. Given Florida's high humidity and pollen counts, managing indoor air quality (IAQ) is critical for your family's health and comfort. We offer a range of advanced IAQ solutions to create a cleaner, healthier indoor environment.

  • Air Purification and Filtration: We can install whole-home air purifiers, including advanced HEPA, media, and electronic air cleaners, to capture dust, pollen, pet dander, and other airborne contaminants. UV air purifiers go a step further by using ultraviolet light to neutralize bacteria, viruses, and mold spores as they pass through your HVAC system.
  • Humidity Control: Excess humidity can make your home feel sticky, promote mold growth, and force your AC to work harder. A whole-house dehumidifier seamlessly integrates with your HVAC system to maintain optimal moisture levels, enhancing comfort and protecting your home.
  • Ventilation Services: Modern, tightly sealed homes can trap stale air and pollutants. We offer ventilation solutions like Energy Recovery Ventilators (ERVs) and Heat Recovery Ventilators (HRVs) to introduce fresh, filtered air into your home without sacrificing energy efficiency.

Expert Answers to Your Common HVAC Questions

Is it better to repair or replace my HVAC system?

This decision often depends on the age of your system, the cost of the repair, and your unit's efficiency. A common guideline is the "$5,000 rule": multiply the age of the unit by the cost of the repair. If the total exceeds $5,000, replacement is often the more economical choice. An older system (12+ years) that requires frequent, costly repairs is also a strong candidate for replacement with a new, energy-efficient model.

How often should I change my HVAC filter in Tallahassee?

Due to the long cooling season and high levels of pollen and dust in Florida, it's wise to check your air filter monthly. For basic 1-inch fiberglass filters, a change every 30-60 days is recommended. For higher-efficiency pleated filters, you may be able to go 3-6 months, but checking it regularly is the best practice for maintaining airflow and air quality.

Should I set my thermostat fan to "On" or "Auto"?

For homes in humid climates like Tallahassee, the "Auto" setting is almost always the best choice. On "Auto," the fan only runs when the system is actively cooling, which allows moisture collected on the indoor coil to drain away. Leaving the fan "On" can reintroduce that moisture into your home's air, increasing humidity levels.

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.
