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).

Most Common Generator Installation Questions

Investing in a whole home generator is a significant decision that brings security and convenience. It’s natural for homeowners to have many questions about the installation process, the equipment, and how it all works. Understanding these details is key to making a confident and informed choice for your home.

Choosing the right size generator is the most critical step in ensuring your backup power system meets your needs. Generator size is not measured in physical dimensions but in its power output, which is rated in kilowatts (kW). A generator that is too small will not be able to power all your desired appliances and can be damaged from overloading. A generator that is excessively large will be inefficient and cost more than necessary to purchase and operate. The key is to find the perfect balance for your specific requirements. Our process at Barney’s Heating and Air is designed to help you do just that.

The first step in sizing a generator is to make a list of all the appliances and systems you want to power during an outage. This includes essentials like your refrigerator, freezer, and lighting. You should also consider comfort items like your furnace or air conditioner, well pump, sump pump, and medical equipment. For each item on your list, we will determine its power consumption in watts. It is important to consider both the “running watts” an appliance uses continuously and the “starting watts” or “surge watts” it needs just to turn on. Motors in appliances like refrigerators and air conditioners require a large surge of power to start up.

Once we have a complete list of your desired loads and their power requirements, we perform a professional load calculation. This calculation totals all the running watts and accounts for the highest starting watts of your largest appliances. This gives us the total kilowatt capacity your generator needs to have to power your home without being overloaded. We will walk you through different scenarios, such as powering only essential circuits versus powering the entire house. This allows you to make an informed decision that balances your needs with your budget, ensuring you get a generator that is perfectly sized for your Clarksville home.

The placement of your new generator is governed by a strict set of safety codes and regulations to protect you and your property. These rules are primarily designed to prevent the risk of fire and carbon monoxide poisoning. Generators produce deadly, odorless carbon monoxide in their engine exhaust, so they must be located outdoors in a well ventilated area. They can never be installed in a garage, basement, or any enclosed space. Our installation experts at Barney’s Heating and Air are well versed in all national and local Clarksville codes and will help you find a compliant and convenient location.

There are specific clearance requirements that must be met. A generator must typically be installed at least five feet away from any door, window, or air intake vent of your home. This prevents the engine exhaust from being drawn back into the house. There are also clearance rules regarding proximity to combustible materials, such as wooden decks or siding. Additionally, local zoning ordinances will dictate how far the generator must be from your property lines. We will perform a thorough site survey to identify all potential locations that meet these critical safety setbacks.

Beyond the safety codes, we also consider practical factors when choosing a location. We look for a spot that is relatively level to minimize the amount of site preparation needed for the concrete pad. We also consider the proximity to your gas meter and main electrical panel to keep the installation costs for fuel lines and wiring as low as possible. Finally, we will discuss aesthetics and noise with you. While modern generators are quieter than older models, we can help you choose a location that minimizes the sound impact on your outdoor living spaces and your neighbors.

Yes, in almost all municipalities, including Clarksville and the surrounding areas, a permit is required for the installation of a whole home standby generator. This is because the installation involves both significant electrical work and, in most cases, gas line plumbing. These systems directly impact the safety of your home, and the permit process ensures that the work is performed correctly and according to all applicable building codes. The permit serves as a formal approval from your local building department to proceed with the project. Attempting to install a generator without a permit can lead to significant fines and may require you to remove the unpermitted work.

The permitting process involves submitting a detailed plan of the installation to the local authorities for review. This plan typically includes electrical diagrams showing how the automatic transfer switch will be wired into your home’s system. It also includes a site plan showing the proposed location of the generator and its compliance with all clearance and setback requirements. If a new gas line is being run, a plumbing plan will also be required. At Barney’s Heating and Air, we handle the entire permitting process for you. We prepare and submit all the necessary paperwork and plans to ensure your project is fully compliant.

After the installation is complete, the permit requires a final inspection by a city or county building inspector. The inspector will visit your home to review our work and ensure that every aspect of the installation meets the code requirements. They will check the electrical connections, the fuel line installation, and the generator’s placement. This third party inspection provides an extra layer of quality control and peace of mind for you as a homeowner. It is the final step in confirming that your new generator system is installed safely and correctly. We coordinate this inspection and ensure our work passes with flying colors.

Just like a car engine, a generator’s engine requires regular maintenance to ensure it remains reliable and ready to operate when you need it most. Routine maintenance is the key to a long and trouble free service life for your investment. Most generator manufacturers recommend a schedule of preventative maintenance that includes regular inspections and service. Neglecting this maintenance can lead to a failure to start during a power outage, which defeats the entire purpose of having a generator. At Barney’s Heating and Air, we offer comprehensive maintenance plans to keep your generator in peak condition.

A typical maintenance schedule includes several key tasks. The engine oil and oil filter should be changed regularly, usually once a year or after a specific number of run hours, whichever comes first. The air filter also needs to be inspected and replaced to ensure the engine can breathe properly. The spark plugs should be checked and replaced as needed to guarantee reliable starting. Our technicians will also inspect the battery, cleaning the terminals and testing its charge to make sure it has the power to crank the engine when called upon. A weak battery is one of the most common reasons for a generator failing to start.

In addition to the engine service, our maintenance visits include a full system check. We will inspect all the electrical connections, wiring, and the automatic transfer switch for any signs of wear or corrosion. We will clean the generator unit, ensuring that all air vents are clear of debris. Most importantly, we will perform a full operational test, simulating a power outage to verify that the generator starts, the transfer switch operates correctly, and the system performs exactly as it should. This regular testing and maintenance provides the ultimate peace of mind that your backup power system is ready for any emergency.

Whether a generator will power your entire house depends on the size of the generator you choose to install. There are essentially two main approaches to a backup power installation. The first option is to install a “whole house” generator. This is a larger kilowatt unit that is sized, through a detailed load calculation, to have enough capacity to run virtually everything in your home simultaneously. This includes large appliances like your central air conditioner, electric range, and clothes dryer. A whole house solution provides the most convenience and ensures that your lifestyle is completely uninterrupted during a power outage.

The second option is to install a smaller generator that provides power only to your home’s “essential circuits.” In this type of installation, the automatic transfer switch is wired to a new sub panel that contains only the circuits you have deemed most important. This typically includes things like your refrigerator and freezer, the furnace fan, a well pump, a sump pump, and selected lights and outlets. This approach is more budget friendly as it allows you to install a smaller, less expensive generator. It provides the security of knowing your critical systems will remain online, even if you cannot run every single appliance in your home.

During our initial consultation, we will have a detailed discussion with you about these two options. We will help you weigh the pros and cons of each approach based on your family’s needs and your budget. We can perform load calculations for both a whole house scenario and an essential circuits scenario. This will give you a clear understanding of the generator sizes and the associated costs for each option. Our goal at Barney’s Heating and Air is to help you select a solution that provides the right level of power and security for your Clarksville home.

The vast majority of residential standby generators are designed to run on one of two common fuel sources: natural gas or liquid propane (LP). The choice between these two fuels often depends on what is available at your property. Natural gas is the most convenient and cost effective option if your home is already connected to a municipal gas supply. The generator can be connected directly to your existing gas line, providing a virtually unlimited fuel source. You never have to worry about refueling, as the generator will draw fuel from the utility line whenever it needs to run.

If your home does not have access to natural gas, liquid propane is an excellent alternative. For this setup, a dedicated LP tank will be installed on your property by a licensed propane supplier. The generator is then connected to this tank. The main consideration with propane is that you have a finite supply of fuel stored on site. You will need to monitor the fuel level in the tank and have it refilled periodically by your propane company. The size of the tank will determine how long your generator can run before a refill is needed. We can help you calculate your expected run time and select an appropriately sized tank.

Both natural gas and propane are clean burning fuels that are reliable and readily available in the Clarksville area. They are generally more stable for long term storage than gasoline or diesel, which is why they are the standard for permanent standby generators. During our site assessment, we will determine which fuel source is the best fit for your home and your needs. Our certified technicians are licensed to install both natural gas and propane fuel lines, ensuring a safe and code compliant connection for your new generator system.
