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."

Thermostat installations and replacements FAQs

It's often worth replacing your old thermostat with a newer model that can enhance your home's comfort and energy efficiency. Upgrading to a programmable or smart thermostat can save you up to $200 per year on energy bills. Plus, smart thermostats offer convenient features like remote control and learning capabilities, making your home more comfortable and easier to manage.

Signs of a bad thermostat include your HVAC system not turning on when it's supposed to or failing to reach the desired temperature. If the thermostat's display is blank or not functioning properly, it could be malfunctioning. Another indicator is the HVAC system running continuously without shutting off or cycling on and off too frequently. You might also notice uneven temperatures throughout your home, with some rooms being too warm or too cold. These issues suggest that the thermostat is failing and may need repair or replacement to ensure your HVAC system operates efficiently.

A thermostat should last between 10 to 20 years, depending on its quality and how well it's maintained. Over time, dust, wiring issues, and general wear can affect its performance. Even if a thermostat is still functioning after 10 years, you might choose to replace it to take advantage of newer energy-saving technologies and smart home integrations. Upgrading to a modern thermostat can improve efficiency, offer more control over your home's climate, and potentially lower energy bills.

The number of thermostats you need depends on your home's size, layout, and heating and cooling zones. In a standard single-zone HVAC system, one thermostat controls the temperature for the entire home. However, larger homes or those with multiple floors might benefit from multiple thermostats linked to a multi-zone HVAC system. This setup can offer better comfort and energy efficiency: It lets you customize the temperature in different areas, so you're only heating or cooling the spaces you're using.

Replacing a thermostat typically takes a professional technician about one to two hours to complete. If you're swapping out an existing thermostat for a similar model with compatible wiring, the process can be done in less than an hour. However, installing a new thermostat that requires additional wiring, such as a smart thermostat, or moving the thermostat to a new location can extend the time to two hours or more. Complex installations may also involve cutting into drywall or integrating with other home systems, which can add to the duration.

There are a few things that can cause your home thermostat to fail. The most simple one is age and cleanliness. Dirt, grease, dust, and other small particles can clog sensors and cause malfunctions in readings. You may also have a failing power supply and loose connections, and the simplest cause is that it isn't installed in the right place in your home so it can't properly sense air temperature. Repairing a thermostat costs around $210.
