I've always been pleased with the expert service from Indoor Comfort Systems. Their installation of my new system a few years ago was superb. I couldn't ask for a better job. Their preventive maintenance program helps ensure my HVAC system runs with utmost efficiency. Earnest, my last preventive maintenance technician, did an outstanding job. He made sure all systems were running as expected, explained everything clearly and concisely, and pointed out small dents in the compressor--most likely caused by debris kicked up by a weed-eater. He had several suggestions for avoiding further and more serious problems. I've chosen to get an air conditioner cover. Problem solved. Thank you ICS.

We have used Annette Hales Indoor Comfort Systems for many years now and they never fail to impress us. One technician who has come out to our home several times name is Ronnie. Ronnie is very kind, respectful and very, very knowledgeable. We were having an issue with our thermostat constantly giving an error message that the auxiliary heat was running too long. Ronnie upon his arrival almost immediately recognized that the return for the heat/air unit was in the hallway next to the MB room and the door was always kept close. He stated that the house was not getting sufficient air flow. Upon further investigation he also noticed that the air ducts were not big enough for the distance the air had to travel. We have had no issues since the corrections were made. Annette Hale’s Comfort System also has great customer service representatives. I would highly recommend them for any HVAC problems you may encounter.

I called with a diagnostic request because one of my thermostats had a blank screen. The technician, Tony, was on time, professional, and efficient. He determined I needed a new thermostat, confirmed the equipment was covered under my warranty, placed the order, and was back within a day to install. The company decided to replace the second thermostat in my home as well, so that both would be alike. In the four years I’ve depended on Annette Hale’s Indoor Comfort Systems, they have proven to be reliable, dependable, and always professional. Highly recommended!

Benefits of Replacing Your AC Unit

Regardless of the make or model of your new air conditioner, you’ll reap the immediate benefits of air conditioning installation and replacement, including:
  • Energy savings

    Did you know your AC can account for 50% or more of your summer energy bills? Upgrading to a more energy-efficient unit can massively reduce your energy costs and save you money every month.

  • Improved comfort

    New air conditioning units will be more efficient and effective at cooling down your home. Without the breakdowns and issues you may have had with your old AC, you’ll be much cooler with a new one!

  • Extended warranties

    Once you invest in air conditioning installation for a new unit, you’ll have years of coverage that will ensure you don’t have to pay for something that goes wrong (but make sure you’re still getting regular maintenance). You can enjoy the peace of mind knowing a large repair cost isn’t looming overhead.
