Annette Hale's Indoor Comfort Systems. We offer quality service at an affordable price. Contact us today about an estimate!

"This was the second system we purchased. The first was a replacement heat pump for our upstairs system. This one was an air conditioner and gas pack heating for the main residence. We purchased this through their rebate offer via Costco. We really wanted this to be a no problems sale. We paid in cash (check) the day before it was installed. The basic unit seems to work correctly and reliably so far. The inside has been comfortable since it was installed. That’s the good side of the story. The unit upstairs was installed with a programmable thermostat - Which I did not particularly want. That programmable thermostat is awkward to use - And I am a degreed electronic engineer! I eventually replaced it with a simple non-programmable thermostat. When I got the quote on the recent main unit replacement, I insisted on keeping my simple to use Honeywell Electronic heating and cooling thermostat. We are retired and one of us is usually home so there is zero reason to use a programmable thermostat and frankly the Lennox programmable one is a misery to use. When the installers arrived I placed the installation manual for the existing Honeywell thermostat on the thermostat itself - Impossible to miss! The main unit was installed correctly and seems to work well. But the installer had difficulty hooking up the Honeywell thermostat due to wiring problems eventually found under the house in the thermostat wiring. It was a warm day on installation day and the heating settings were only briefly tested. Then the AC settings were tested and the installer was very quickly out the door. A week or so later it got cool and I switched to heating. In heat mode the circulation fan would not run unless the heat was actually heating despite the thermostat being set to fan “ON”. I am an electronic engineer and I suspected there was an error in the hookup of the thermostat. Turns out I was correct - The installer had set the internal thermostat switch to “heat pump” instead of AC with gas heating he had installed. Furthermore he had hooked up one thermostat wire to the wrong terminal. He has to go out of his way to make these mistakes instead of leaving the thermostat wiring and internal switch setting as it had been. I corrected these two errors and then the system ran correctly. Anyone can make a mistake, but it takes something “special” to be so sloppy in testing the installation not to notice it wasn’t acting correctly! Well I thought the only problem I had with Annette Hale Indoor Comfort Air was the sloppy installer. Just this morning the sales person called me to ask if we had paid for the unit from several weeks ago! The same sales person who picked up the check the day before - Which had cleared the bank some time ago. I may not be have been very polite with this person - It seems their accounting people are just as sloppy as their installer. Eventually I was called back and he apologized that they had been paid, they just somehow credited it wrong. I would never again use this installer. They screwed up part of the installation and then may have tried to collect twice for the same work! Sloppy, very sloppy! The Lennox equipment itself except for the miserable programmable Lennox thermostat works well and seems of good quality."

Complete residential and commercial heating and cooling service and sales including Geo Thermal systems, sheet metal fabrication, grease hood installation, grease duct fabrication and attic insulation. Proud member of the TVA Energy RIght Partners program.

"We were very happy with Bama Air Systems. They came out for an estimate on a Mini-Split in a timely manner, and had a quick turn-around time for installation. Their service professionals, Austin, Zach and JC, were on time, friendly and courteous, and very efficient. The installation took less than a day, and they cleaned up the construction debris thoroughly. We would definitely recommend them for your HVAC needs."
