How To Tell If You Need AC Maintenance in Keystone Heights, FL

If you live in Keystone Heights, you know that it’s hot most of the year. If you use your air conditioner to keep the heat back all year, it pays to get a proper maintenance schedule underway. If you notice any of the following issues, you may need to schedule an appointment even sooner:

Higher Energy Bills

If your air conditioner is inefficient, old, or otherwise not doing well, you may experience higher energy costs to run it all year. A good way to look for this is by evaluating your energy bills every month. Keeping track of any unexplained upticks can help you determine if your air conditioner is the problem or if something else in the household is causing the extra energy usage.

Short Cycling

Short cycling is when an air conditioner unit runs for about 20 minutes before turning off. This is because the air conditioner cannot fully cool the home, resulting in short cycling and gradual wear on the machine. If you’re experiencing short cycling, it could be due to any number of things, including:

  • Clogged air filters
  • Ineffective cooling
  • Incorrect thermostats
  • Age

If your air conditioner short cycles, the best thing to do is call our experts to schedule a professional maintenance service. If you allow it to continue short cycling, the air conditioner may not live for its full life cycle. Plus, a short-cycling system can increase your energy bills while struggling to cool your home, leaving you with a more expensive and unreliable system.

He was here for a couple of hours troubleshooting my AC as to why it wasn’t communicating with my Thermostat. He was on hold with the Lenex Technical Support and never got them to answer back. Another tech suggested a work around to test system and it worked. Got us a working unit until they could replace the wiring going to the electronics. Just a standard service call price.
Response from the owner:Richard we apologize for the inconvenience but appreciate your patience and understanding. We are diligently working with the manufacturer to get this resolved for you as soon as we can. Thank You!

Robert arrived in short order to an unexpected AC/Heat thermostat issue on a late Saturday afternoon. After initial trouble shooting, he was able to trace the cause to a unique mishap within the outside unit. Throughout the process he was professional, courteous and engaging in keeping us informed during the repair process. He proved to be a superb technician and a person of great character - 5 star.
Response from the owner:James, thank you for taking the time to share this.

Southern Air has been great to work with; their techs are always on time, friendly, professional, and they explain things in an easy-to-understand way even if you don't know anything about how air conditioners work. Getting twice-yearly maintenance on my unit really gives me peace of mind that it's being kept up and if anything does go wrong I'll know about it before it gets too bad.
Response from the owner:We are so glad to hear it! Thank you for your review!

    We’ve had a great experience with Southern Air in Palatka, especially as members of their Comfort Club. It’s been a really great value for us because a technician comes out twice a year to check everything over and make sure our system is working well and staying on track.

    This most recent visit was with Dylan, and he was excellent—professional, thorough, and easy to talk to. He cleaned our vent and spent real time going through the system to make sure everything was running exactly as it should. You could tell he cared about doing the job right, not rushing through it.

    Highly recommend Southern Air, and if you’re considering the Comfort Club, it’s absolutely worth it.
    Response from the owner:Kristen, thank you for the kind review and for being part of our Comfort Club. I’m glad the twice-a-year checkups have been a good value for you, and that Dylan took the time to thoroughly go through your system, clean the vent, and make sure everything was running the way it should. We really appreciate the recommendation.
