Frequently Asked Questions

  • When is it time to call a professional?

    If you suspect an issue with your AC, the earlier you call us the better. While some signs of trouble are easy to spot, it can take the eye of a trained professional to catch others. If you’ve heard strange noises, noticed intermittent cooling, or if your unit just isn’t running like it used to, give us a call.

  • Does my A/C need maintenance?

    Almost every system out there will need the occasional tune up to stay at its best. Having an expert check out your system once in a while can help to catch issues early on, before they turn into major headaches. Plus, regular maintenance can lower costs by increasing system efficiency.

  • Do I need to replace my A/C unit?

    While repairs can often take care of most issues, sometimes it is more cost-effective to install a new system. At Horizon Services, LLC, we can help you understand your options for both repairs as well as which new units would be best for your property.

  • How quickly can you get to me?

    When you have trouble with your air conditioner, you don’t have time to wait for an expert to be available. That’s why we offer same day repair services and next day installations. Of course we can also set up future appointments for when you have the time.
