A Guide to Thermostat Replacement
in Amarillo, Texas

Weather in Amarillo, Texas, varies between lows of 25°F and highs of 90°F or more. You need a reliable thermostat replacement to manage Amarillo's hot summers and dry, frigid winters.

Thermostats let you control your home's HVAC system. Without them, your AC and heater will overwork themselves and eventually break down when you need them most.

Some thermostats perform the bare minimum, like turning the unit on and off, and adjusting indoor temperatures as needed. Other models come with more features, like humidity control, WiFi settings, or programmable heating and cooling; these extra features improve efficiency, air quality, and save Amarillo residents $200 in energy bills or more.

A broken thermostat increases utility bills, but an improperly installed thermostat also causes more trouble than it's worth.

How to Tell If Your Thermostat is Broken

Does your home feel unusually cold during winter despite cranking up the heat? Are you sweltering during summer with the AC on full blast? It's easy to misdiagnose the problem and point the finger at the furnace, but your thermostat may be the culprit if your HVAC system checks out.

These are the telltale signs of a broken thermostat:

  • The thermostat turns on and off for short periods of time

  • It won't power on at all

  • It turns on but does nothing

  • Rooms that aren't heated (or cooled) at all

  • Thermostat settings don't work

  • Power lights won't light up on the thermostat

  • Plummeting temperatures indoors

If your thermostat can't properly regulate your HVAC system, it will increase the risk of indoor air pollution and common colds from frigid, dry air indoors.

It's not just old thermostats that do this, either. Improperly installed thermostats are just as bad. Installation problems often occur when homeowners install thermostats themselves or hire an electrician, not an HVAC technician, to install the thermostat.

Signs of an Incorrectly Installed Thermostat

Incorrectly installed thermostats are a little deceptive. You're less likely to suspect a brand new thermostat, but if you watch closely, it'll exhibit signs of a broken thermostat.

Don't let the lights on your thermostat fool you. That new thermostat may look like it's on, but may be unresponsive. The central heating system may kick on, but that doesn't mean your thermostat is properly regulating your heating and cooling. It may run for hours without letting you stop it or shut off right before reaching its target temperature.

So, what went wrong?

Bad Thermostat Placement

One of the most overlooked signs of an improperly installed thermostat is placement. Thermostats measure room temperature to regulate heating and cooling correctly; that's why placement is so important.

Installing Thermostats in Direct Natural Sunlight

Thermostats should not be installed in areas that get bright, direct sunlight. Direct light results in false temperature readings and settings. If your newly installed thermostat is located next to a skylight or a window with lots of natural sunlight, that's a problem.

Hot Kitchens

Another problem area is the kitchen. Never install a home thermostat in a kitchen.

It's probably the warmest area of your home. Kitchen temperatures alternate dramatically as the room fills with steam, oven heat, and heat generated from appliances. These elements trick the thermostat into "thinking" that your home is hotter than it really is.

Since kitchen heat radiates through the walls, you shouldn't install a thermostat on the opposite side of the kitchen wall, either.

Installing Near Windows and Doors

Thermostats installed right next to doors and windows are another problem. Cold drafts impact temperature readings and prevent the AC from kicking on during hot summers. The constant opening and closing of doors and windows also create drafts.

Thermostats Near Air Vents

Thermostats installed next to air vents also produce false temperature readings.

These false readings are called "ghost readings," this will cause your thermostat to cool down or heat up before your home has a chance to catch up.

Hallways and Entrance Ways

Your hallway may seem like a decent place to install a thermostat, but it's one of the worst locations.

HVAC technicians understand that thermostats work best in common areas, like living rooms, family rooms, or another central spot in your home. Your thermostat measures the temperature of the area, and that includes body heat.

Hallway thermostats read more cold than living rooms, which can pose problems during summer. Thermostats are more likely to get damaged in narrow spaces, as well.

Bad Installation Wiring

Bad wiring is one of the most common (and hazardous) signs of an incorrectly installed thermostat. This happens when homeowners troubleshoot thermostat wiring themselves or enlist a general election who's not experienced with HVAC wiring.

Incorrect HVAC wiring is more likely to blow out circuits; plus, you risk shocking yourself, or worse, electrocuting yourself in the process. If you're getting shocks, that means you're sending too many electrical currents through the HVAC system.

Poor DIY wiring doesn't just affect thermostat function. It can also damage your entire heating and cooling system and jeopardize your warranty. If you attempt to do your own wiring, you will need more than basic electrical wiring knowledge, and even that is a risk.

Thermostat Replacement vs. Repair

You know something isn't working but is a full thermostat replacement necessary?

Repairing thermostats versus replacing them is a common tug of war for homeowners. Owning a home is expensive, and it's understandable to cut costs when you can. Unfortunately, the cost of multiple repairs and DIY solutions exceed the long-term costs of professional thermostat replacements.

If you want to troubleshoot your thermostat before calling an HVAC service, there are few things you can do.

For starters, make sure the right setting is lit up on the face plate screen. This may seem obvious, but it's easy to overlook this part when you're in a hurry or stressed.

Next, adjust the temperature by a few degrees. You should hear a click sound followed by airflow. You may need to wait a few minutes for the system to register the settings.

If you have a mechanical thermostat with an adjustable dial, dust around the dial to see if that helps. Old thermostats accumulate dust quickly.

Your electrical thermostat may be low on batteries. Change your batteries to see if anything changes. If your thermostat is still malfunctioning, call an expert who can help.

If basic troubleshooting doesn't improve thermostat function, it's time to replace it. An HVAC technician can repair faulty wiring, but consider the money you'll save with a full replacement.

Which Thermostat Should You Choose?

Standard mechanical thermostats are still available. These thermostats let you turn on your HVAC and adjust your home's temperature, but you don't get the added benefits of a Smart thermostat. You can't program mechanical thermostats but you can manually adjust them if you prefer.

There are also non-programmable electric thermostats available. You can't program these either, but you can still purchase an energy-efficient model.

The Benefits of Programmable Thermostats

Programmable thermostats are great if you don't want to manually adjust your settings every time it gets too warm or chilly in the house.

They're also convenient if you frequently forget to turn off your AC or heater before bed. Programmable models also prevent your HVAC system from overworking itself, which lowers your energy costs. If you deal with fluctuating temperature changes, this is a great choice.


Did you know that you can connect a thermostat to your WiFi connection?

These thermostats are accompanied by an app that lets you control your settings directly from your mobile device. This option is great if you want to adjust your home's temperature before you step through the door.

Smart Thermostats

Smart thermostats are the most innovative option. These thermostats take WiFi-connect models to another level. Smart thermostats "learn" the heat and cooling patterns of your home to improve comfort and energy efficiency.

These models connect to WiFi and let you control and override settings from a connected device. Smart thermostats also come with voice controls, which may be compatible with your current AI virtual assistant device. Your thermostat will even remind you of upcoming maintenance checks.

How to Choose an HVAC Service in Amarillo, Texas

You need a service that understands thermostat installation, Amarillo's weather conditions, and your home's heating and cooling needs.

Transparency matters. Work with a service that provides fair estimates. Thermostat replacements can cost up to $900 for programmable and non-programmable models, and up to $1,600 for smart thermostats. Analog thermostats are the least expensive, but you can save even more with an energy-efficient replacement.

An experienced technician will also discuss the installation process, install only high-quality equipment, and provide tips on preventing thermostat problems in the future.

Don't pay the price of high energy bills. Enjoy a thermostat replacement that works properly and saves you money. Remember these tips as you look for a replacement and service that can help.
