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!!!

HIGHLY RECOMMEND!!! My A/C went out late Friday night and not many companies were wanting to help and look at my unit until after the weekend and holiday was over, but Barney’s heating and air responded ASAP, and was here first thing in the morning on Saturday! The technician gave me an exact time and was here on time, other companies gave me a big time frame/window 8am-6pm and that just didn’t work for us. This company is affordable and willing to work with you. Definitely will call them again!! Thank you!

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 Furnace Installation Questions

Investing in a new furnace is a major decision for any homeowner. It is important to be informed about the process and your options. Here are answers to some of the most common questions we receive about furnace installation.

AFUE stands for Annual Fuel Utilization Efficiency. It is a percentage that measures how efficiently a furnace converts fuel into usable heat for your home. For example, a furnace with a 95 percent AFUE rating converts 95 cents of every dollar you spend on fuel into heat. The remaining 5 cents is lost through the venting process. A higher AFUE rating indicates a more efficient furnace. This is the standard measurement used to compare the performance of different furnace models. The federal government mandates a minimum AFUE rating for all new furnaces sold in the United States.

Furnaces are generally categorized into two main groups based on their AFUE rating. Standard efficiency furnaces typically have an AFUE rating of around 80 percent. These furnaces are non condensing. They vent hot combustion gases directly outside through a metal flue pipe. This means that about 20 percent of the heat generated by the fuel is lost with those exhaust gases. While less efficient, 80 percent AFUE furnaces are often less expensive to purchase and install. They can be a suitable option in some situations, particularly when replacing an existing 80 percent unit.

High efficiency furnaces, also known as condensing furnaces, have AFUE ratings of 90 percent or higher. Some models can reach up to 98 percent efficiency. These units have a secondary heat exchanger that extracts additional heat from the exhaust gases. This process cools the gases to the point where water vapor condenses out of them, which is why they are called condensing furnaces. Because so much heat is extracted, the exhaust gases are cool enough to be vented outside through PVC pipes. While they have a higher upfront cost, high efficiency furnaces can save you a significant amount of money on your heating bills over the life of the unit.

Determining the correct size, or capacity, for your new furnace is one of the most critical steps in the installation process. Furnace capacity is measured in British Thermal Units, or BTUs. This number represents the amount of heat the furnace can produce per hour. Many people mistakenly believe that getting a bigger furnace is always better. However, an oversized furnace is actually very inefficient and can lead to a host of problems. It will heat the house up too quickly and then shut off, a process called short cycling. This causes uncomfortable temperature swings and puts excessive wear and tear on the furnace components.

The only accurate way to determine the right furnace size for your home is to have a professional contractor perform a Manual J load calculation. This is an industry standard method that calculates your home’s specific heating needs. The calculation takes into account a wide range of factors. These include the square footage of your home, the quality of your insulation, the number and type of windows, the air infiltration rate, and the local climate in Clarksville, TN. It is a detailed and scientific process that results in a precise BTU requirement for your home. Any contractor who tries to size a furnace based on square footage alone is not following best practices.

Once the Manual J calculation is complete, we can select a furnace with a BTU output that closely matches your home’s heating load. This ensures that the furnace will run for longer, more consistent cycles. This provides much more even and comfortable heat throughout your home. A correctly sized furnace also operates at its peak efficiency, which saves you money on your fuel bills. It also reduces the strain on the system’s components, which can lead to a longer lifespan and fewer repairs. We perform a load calculation for every single furnace installation we do to guarantee these results.

Yes, a permit is required for a new furnace installation in Clarksville and Montgomery County. Installing a furnace is a major mechanical project that involves fuel lines, electrical wiring, and venting systems. These systems have a direct impact on the safety of your home and its occupants. Building codes are in place to ensure that this work is done correctly and safely. The permitting process ensures that the installation will be reviewed and inspected by a local building official. This provides an independent, third party verification that the work complies with all safety standards. It is a crucial safeguard for you as a homeowner.

As a licensed and professional HVAC contractor, Barney’s Heating and Air takes full responsibility for the permitting process. We handle all the paperwork and submit the application to the local building department on your behalf. We are well versed in the specific codes and requirements for furnace installations in our area. We will also coordinate and schedule the necessary inspections with the city or county inspector. The cost of the permit is included in our installation proposal, so there are no hidden charges. Our goal is to make the process as smooth and hassle free for you as possible.

You should be very cautious of any contractor who suggests that you can skip the permitting process to save money. Working without a permit is a major red flag. It often means the contractor is not licensed or insured. An unpermitted installation could void your homeowner’s insurance. It could also create significant problems if you try to sell your home in the future. Most importantly, it could put your family’s safety at risk. A permitted and inspected installation provides peace of mind, knowing that the job was done right and your new furnace is safe to operate.

It is often a very good idea to replace your air conditioner and furnace simultaneously. In most homes in our area, the furnace and air conditioner share the same indoor blower motor. The blower motor, housed in the furnace or air handler, is responsible for circulating both hot and cool air throughout your home. When you replace only the furnace, you have a brand new heating component paired with an old blower motor. The efficiency and performance of this shared component are critical to both systems. Mismatched systems, with components of different ages and technologies, may not perform optimally.

Modern HVAC systems are designed to work together as a complete, matched system. The furnace, evaporator coil (the indoor part of the AC), and the outdoor AC unit are all engineered to be compatible. This ensures that you get the full efficiency and performance that you are paying for. Installing a new, high efficiency furnace with a new, high efficiency air conditioner creates a system that is perfectly balanced. This can lead to greater energy savings and improved comfort compared to replacing just one component at a time. It ensures that all parts of your HVAC system are on the same page.

From a financial and logistical standpoint, replacing both systems at once can be very advantageous. The labor costs are often lower when both units are installed at the same time, as our team is already on site with all the necessary equipment. It is one installation project instead of two separate ones. It also means you will not have to worry about another major installation in a few years when the other unit fails. If both your furnace and air conditioner are of a similar age, typically over 10 to 15 years old, replacing them together is usually the most practical and cost effective long term strategy.

The removal of your old furnace is the first major step on installation day. The process must be done carefully and safely by our trained technicians. First, we will shut off the electrical power and the gas supply to the unit. This is a critical safety precaution. The gas line is then professionally disconnected from the furnace. The electrical wiring and the thermostat controls are also disconnected. We take care to label wires if necessary to ensure a smooth connection to the new unit. The process is methodical and follows strict safety protocols.

Once all the utilities are disconnected, we will separate the old furnace from the ductwork and the venting system. The connections to the supply and return air plenums are unfastened. The vent pipe, or flue, is also disconnected. At this point, the old furnace is free and ready to be removed from your home. Our technicians will carefully maneuver the unit out of your basement, crawlspace, or closet. We use dollies and teamwork to move the heavy equipment safely, taking care not to damage your walls, floors, or doorways.

After the old furnace is removed from your home, we will load it onto our truck for proper disposal. We are committed to being environmentally responsible. The old unit is taken to a designated recycling facility where it is disposed of in accordance with all environmental regulations. The metals are recycled, and any hazardous materials are handled appropriately. We also take this opportunity to thoroughly clean the area where the old furnace was located. This prepares a clean slate for the installation of your new, efficient heating system.

Absolutely. Testing the new furnace after installation, a process known as commissioning, is one of the most important parts of our job. We would never install a new piece of equipment and leave without ensuring it is operating perfectly and safely. This comprehensive testing phase is what separates a professional installation from the work of an amateur. It is our final quality control check and our guarantee to you that the system is ready for service. We follow a detailed checklist to test every aspect of the furnace’s operation.

The commissioning process begins with extensive safety checks. We use an electronic gas detector to check our new gas line connection and all the gas fittings inside the furnace cabinet. We want to be 100 percent certain that there are no gas leaks. We then power up the furnace and test the sequence of operations. We verify that the igniter glows, the gas valve opens correctly, and the burners light smoothly. We also test all the built in safety controls, such as the high limit switch, to ensure they will shut the furnace down if an unsafe condition is detected.

Next, we move on to performance tuning. We use a manometer to measure the gas pressure and adjust it to the precise level specified by the manufacturer. This ensures clean combustion and optimal efficiency. We also measure the temperature rise, which is the difference in temperature between the air entering and leaving the furnace. This tells us if the airflow is correct for the amount of heat being produced. We will make adjustments to the blower speed if necessary. This entire process ensures your new furnace is not only safe but is also running at its peak performance and efficiency.
