Dual Zone HVAC systems offer superior temperature control, allowing you to create customized comfort zones in different areas. However, like any complex system, they may encounter issues from time to time. That’s where Keith Key Heating & Air comes in.

We are your trusted partner in providing exceptional air conditioning repair in Tallahassee, FL, and surrounding areas. Our professionals will be happy to come out and inspect your dual-zone HVAC system. We will troubleshoot the issue, identify the underlying cause, and provide efficient solutions.

In The Meantime Here Are Five Troubleshooting When Your Dual Zone HVAC Is Not Working:

• Check the Power Supply

The first step in troubleshooting your dual zone HVAC system is to ensure it has a reliable power supply. Start by checking the circuit breaker to ensure it hasn’t tripped. If the breaker has tripped or stumbled, reset it and see if the system powers on. Additionally, inspect the power switch on the unit itself to ensure it is turned on. If the circuit breaker and power switch are in the correct position, move on to the next troubleshooting step.

• Examine the Thermostats

Dual-zone HVAC systems use separate thermostats to control different zones. Check each thermostat to ensure they are functioning correctly. Make sure they have power and are set to the desired temperature. Checking the thermostat batteries is crucial, as low battery levels can cause malfunctions. Replace the batteries if necessary. If the thermostats appear to be working correctly, but the problem persists, move on to the next troubleshooting step.

• Inspect The Air Filters

Clogged air filters can block airflow and impair the performance of your dual-zone HVAC system. Dirty filters reduce the system’s efficiency and can cause freezing or overheating of the coils. Regularly inspect and replace the air filters according to the manufacturer’s recommendations. Clean air filters promote airflow, enhance indoor air quality, and ensure optimal HVAC system performance.

• Clear Obstructions And Debris

A common cause of HVAC system malfunctions is the presence of obstructions or debris around the outdoor unit. Check for any objects blocking the airflow, such as leaves, branches, or dirt. Ensure there are at least two feet of clearance around the unit. Clear any obstructions and clean the area to improve airflow and system efficiency.

• Schedule Professional Maintenance

While troubleshooting steps can resolve minor issues, it’s always recommended to schedule regular maintenance by qualified professionals. A professional HVAC technician can conduct a comprehensive inspection, identify underlying problems, and perform necessary repairs or adjustments. Regular maintenance not only ensures the optimal performance of your dual zone HVAC system but also helps prevent potential issues from arising in the future.

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.
