A/C had been out for a couple days. Heat index 105° , 90 ° in house. I called 15 + HVAC companies and the earliest appointment time anybody could come was a week away. I called Barneys . He shot me straight and told me " I'll get you up and going today but it's going to be in the evening." He showed up about 7 pm which is perfectly fine as it was hot. He fixed the problem in 15 mins ( needed refrigerant ) He charged a very fair price. He stands by his word. LIFESAVER!! VERY COOL NOW!!!

First time (in this house) getting our heat pump inspected. Technician was detailed in explaining what was both good & bad about our 12 year-old system. He explained that our system was still functional but also showed us a part that might fail in the future. He tested the part in our presence & gave us a fair price for replacement (which we did). We were comfortable enough with the service that we are likely to purchase a service/maintenance agreement this Fall.

Most Common Thermostat Installation Questions

Before upgrading your home’s thermostat, you likely have some questions about the process and the benefits. Understanding the details helps you make the best choice for your heating and cooling needs. Here we answer some of the most common questions our customers in Clarksville ask about thermostat installation.

The primary benefit of a smart thermostat is its ability to significantly reduce your energy consumption and lower your utility bills. These devices go beyond simple scheduling by learning your household’s patterns and preferences. They can automatically adjust the temperature when you are away and prepare the home for your return, ensuring you never waste money heating or cooling an empty house. Many smart thermostats provide detailed energy reports, giving you valuable insights into your usage and identifying further opportunities to save. This level of intelligent control can lead to substantial savings year after year.

Another major advantage is the unparalleled convenience and control that smart thermostats offer. They connect to your home’s Wi-Fi network, allowing you to monitor and adjust your home’s temperature from anywhere in the world using a smartphone app. This means you can turn up the heat on your way home from a trip or check if you forgot to adjust the AC after leaving the house. Many models also integrate with voice assistants like Amazon Alexa or Google Assistant, allowing you to change the temperature with a simple voice command, adding a layer of hands free convenience to your daily life.

Smart thermostats can also improve the overall health and maintenance of your HVAC system. They can send you maintenance reminders, such as when to change your air filter, which is crucial for efficient operation. Some advanced models can even monitor your HVAC system’s performance and alert you to potential issues or malfunctions before they become major problems. This proactive monitoring can help you avoid unexpected breakdowns and extend the lifespan of your heating and cooling equipment. A smart thermostat is not just a gadget; it’s an investment in a smarter, more efficient, and more comfortable home.

The optimal location for a thermostat is crucial for it to accurately read your home’s temperature and control your HVAC system effectively. The best spot is typically on an interior wall in a central, high traffic area of your home, such as a main hallway or living room. Placing it here ensures it measures the average temperature of the living space, preventing one area from becoming too hot or cold. The thermostat should be mounted about 60 inches, or five feet, off the floor to sense the temperature at an appropriate height, away from the cooler air near the floor and warmer air near the ceiling.

It is just as important to know where not to install a thermostat. You must avoid locations that can give false temperature readings, as this will cause your HVAC system to run inefficiently. Keep the thermostat away from direct sunlight, as the heat from the sun will make it think the room is warmer than it is, causing the AC to run too much. Similarly, avoid placing it near drafts from windows, doors, or supply vents, which can make it register a cooler temperature. It should also be kept away from heat generating appliances like televisions, lamps, or kitchen equipment.

Our professional technicians can help you determine the absolute best location for your new thermostat during the installation process. We will evaluate your home’s layout, airflow patterns, and your family’s living habits to find the most suitable spot. In some larger or multi level homes, a single thermostat may not be enough to maintain consistent comfort everywhere. In these cases, we might recommend a zoning system with multiple thermostats, each controlling a different area of the house for truly customized comfort and efficiency. Proper placement is the foundation of your new thermostat’s performance.

For a straightforward thermostat installation where you are replacing an old one in the same location, the process is typically very quick. A professional HVAC technician can usually complete this type of installation in about 30 to 60 minutes. This includes safely disconnecting the old unit, mounting the new thermostat’s wall plate, connecting the wires correctly, and attaching the new faceplate. The technician will then power the system back on and walk you through the basic functions of your new device. It is a fast and simple upgrade with immediate benefits for your home.

The installation time can be longer if the job is more complex. For example, if new wiring is required to run to the thermostat’s location, the process will take more time. This is often the case when upgrading to a smart thermostat that requires a C wire (common wire) for continuous power, and your existing setup does not have one. Running a new wire from the HVAC system’s control board to the thermostat can take an additional hour or two, depending on the home’s construction and the distance the wire needs to travel through walls or ceilings.

Other factors that can extend the installation time include installing a thermostat in a brand new location or setting up a more complex system with zoning controls. If you want to move the thermostat from a poor location to a more optimal one, this will also involve running new wires. Setting up a smart thermostat for the first time also includes connecting it to your home’s Wi-Fi network and helping you download and configure the smartphone app. Despite these variables, most thermostat installations, even the more complex ones, are completed by our professionals within a few hours.

A C wire, which stands for “common wire,” is a low voltage wire that provides a continuous flow of 24 volt power from your HVAC system to your thermostat. Traditional mechanical or battery powered thermostats did not need this constant power source because they either used mercury switches or could draw enough power from batteries. The C wire completes the electrical circuit, allowing the thermostat to have a dedicated power source without interfering with the heating or cooling switching functions. Its primary purpose is to power the advanced features of modern thermostats.

You will likely need a C wire if you are planning to install a smart thermostat or a high end programmable thermostat with features like a large, backlit digital display or Wi-Fi connectivity. These features consume more power than can be reliably provided by batteries or by “power stealing” from the other HVAC control wires. Without a C wire, a smart thermostat may not function correctly; you might experience issues like the Wi-Fi connection dropping, the screen not working, or even the thermostat causing your HVAC system to behave erratically. Most manufacturers of smart thermostats list a C wire as a requirement.

If you remove your current thermostat from the wall and do not see a wire connected to the “C” terminal, you may not have one readily available. However, there might be an unused wire tucked back inside the wall that can be connected on both ends to serve as the C wire. A professional technician can safely check your wiring at the thermostat and at the HVAC system’s control board to determine if you have one. If not, we can easily run a new wire or install a power adapter to ensure your new thermostat has the reliable power it needs for optimal performance.

A programmable thermostat saves you money by eliminating the energy waste associated with heating or cooling your home when it is unnecessary. It allows you to create an automated schedule based on your daily and weekly routines. For instance, you can program the thermostat to automatically lower the heat or raise the air conditioning temperature by several degrees while everyone is at work or school during the day. You can also schedule a similar setback for the overnight hours when everyone is asleep under the covers. This simple act of automating temperature setbacks is the core of how these devices generate savings.

By consistently following this pre set schedule, the thermostat reduces your HVAC system’s runtime during periods when maximum comfort is not needed. According to the U.S. Department of Energy, using a programmable thermostat to set back the temperature for eight hours a day can reduce your annual heating and cooling costs by up to 10%. This is a significant saving that can pay for the cost of the new thermostat in a short amount of time. It achieves these savings without sacrificing comfort, as you can program it to return to your preferred temperature shortly before you wake up or arrive home.

The key to unlocking these savings is using the programming features correctly. Many people install a programmable thermostat but then treat it like a manual one, overriding the schedule and leaving it at one temperature all the time. This completely negates its energy saving potential. Taking the time to set a schedule that reflects your lifestyle is crucial. Modern programmable thermostats are very user friendly, with intuitive interfaces that make it easy to set different programs for weekdays, weekends, or even specific days, ensuring you can “set it and forget it” and enjoy the savings effortlessly.

In the vast majority of cases, a new thermostat will work perfectly with your existing HVAC system. Most modern thermostats, from simple digital models to advanced smart ones, are designed to be highly compatible with the standard heating and cooling systems found in homes today. This includes common setups like a gas furnace paired with a central air conditioner. As long as you have a standard low voltage system, you will have a wide range of compatible thermostat options to choose from. Our team can help you select a model that perfectly matches your needs.

However, there are certain types of HVAC systems that require specific kinds of thermostats to function correctly. For example, heat pump systems require a thermostat that has special settings to control the reversing valve and auxiliary or emergency heat strips. Similarly, multi stage heating or cooling systems, which have different levels of output, need a thermostat that is capable of controlling these multiple stages effectively. Using a basic thermostat with a complex system like this would prevent you from taking advantage of its energy saving features and could lead to inefficient operation.

Our professional technicians at Barney’s Heating and Air are experts at ensuring compatibility. During our consultation or at the time of installation, we will identify the exact type of HVAC system you have in your Clarksville home. We will then verify that the new thermostat you have chosen is fully compatible and has the necessary features to control your equipment properly. This crucial step guarantees that your new thermostat will not only work, but will also optimize the performance and efficiency of your entire heating and cooling system, providing you with reliable comfort for years to come.
