"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."

"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."

Boiler Repair questions, answered by experts

Yes, it is OK to turn off some radiators, and you’ll save money on heating costs if you make it a regular habit to turn your radiators off in unused rooms that don’t need heat. That said, turn them back on when you need to heat your whole home instead of cranking up the dial on the ones you haven’t closed to compensate. The latter will result in higher heating costs and more wear and tear on your system.

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.

At minimum, you should plan to have your HVAC system serviced once per year, usually leading into either the summer or winter before it sees heavy usage. If you live in a particularly cold, hot, or humid climate, consider servicing your HVAC system twice per year—once in the spring and once in the fall—to keep it running efficiently and prevent it from going down in the high-demand seasons. You can also schedule one-off services if you notice issues like uneven heating or cooling, poor performance, or strange noises from your equipment.

In most cases, it’s worth it to repair a radiator that isn’t functioning properly. Provided you’ve ruled out any underlying issues with your boiler or circulating pumps, problems with radiators are typically easy for a professional to diagnose and fix. In most cases, your heating radiator repair won’t cost you more than $100 to $200, which pales in comparison to the cost to replace a radiator, an average of $1,500. It’s best to call in a professional to see which solution is ideal for your situation.

Most HVAC companies charge a flat service call fee of between $75 and $150, which includes traveling to your home and inspecting your system to find the underlying problem. Keep in mind that these prices only include diagnostics and the actual repairs will usually be billed separately. If you’re calling for routine service, the service call will be included in your inspection and tune-up, with the total sitting around $150. Your prices could be a little higher if you have a very large home with multiple condensers and air handlers, as inspections and servicing take longer.
