Heating and air conditioning are top concerns, along with running water and hot water. All of these items are high-load appliances and require a high capacity to start. These actions consume significant power and could quickly drain a home battery.
The most reliable source of power for extended or unpredictable power outages is a home backup generator. The generator, which in most cases is connected directly to a home’s natural gas line, has a constant supply of fuel and can operate through extended outages, keeping homes safe, lit and powered. For people concerned with a loss of natural gas supply during a storm, generators can be fueled by a dedicated LP tank as well. With this continuous fuel source, generators are much better able to face the unpredictability of dangerous, storm-prompted or lengthy outages rather than a home battery, which relies on an external power source to recharge it after only a few hours of use.
According to the U.S. Energy Information Administration, in 2013 the average annual electricity consumption for a U.S. residential utility customer was 10,908 kilowatt hours (kWh). This translates to about 30 kilowatt hours per day.
Owner’s manuals and other technical / repair information can be downloaded from Generac's Product Support Page or contact Kelley Brothers for further assisance.
Generac generators are equipped with overload protection. In the rare event of an overload, the generator’s circuit breaker will trip, disconnecting the unit from the load. Simply correct the overload and reset the breaker in the generator. For more information, please consult your owner's manual or contact Kelley Brothers.

Yes, simple maintenance is required. All generators require periodic oil and filter changes to ensure maximum performance for years of reliable service. Preventative maintenance kits are available, and Kelley Brothers offers annual maintenance contracts for a worry-free ownership experience.
As an option, Generac offers the Guardian Series systems prepackaged and pre-wired with comprehensive installation instructions. You could perform the simpler site preparation steps and have a professional make the electrical panel and fuel connections, or you could complete the entire installation yourself. However, for safety reasons and to ensure adherence to all local, state and national electrical codes, particularly for non pre-wired or larger systems, we recommend you use an authorized Generac dealer, like Kelley Brothers.
The most logical way to determine your needs is to envision your home without power. Some outages may be short in duration, while others could last for days or weeks. What would your family miss during an outage? With some basic information you can determine an estimated size by using Generac's Generator Sizing Calculator. The very best way to understand your options and work within your budget is to schedule a free in-home assessment with Kelley Brothers. During your consultation you will receive the personalized attention and detailed evaluation you need to find a solution that works for your needs.  
No...the generator fuel costs would be much more expensive than buying power from the utility company since their cost to produce electricity is divided among thousands of customers. Our automatic generators are produced for use as backup to utility power specifically and should not be used as primary power. Please refer to the warranty policy for additional information.
In addition to its sturdy galvanneal steel enclosure, Generac is one of the few companies to offer premium aluminum enclosures for its residential backup generators. Aluminum enclosures are naturally rust and corrosion resistant. For salt air or high humidity conditions, aluminum is highly recommended to ensure decades of worry free service.
Unlike other engines, used in backup power generation, Generac OHVI engines are made specifically for generators. They are engineered to run for the long periods of time required during a severe power outage or on a job site, utilizing the same type of pressurized oil lubrication used to give automobile engines long and trouble-free lives.
The engines! Air-cooled generators come with engines that use fans to force air across the engine for cooling, while liquid-cooled generators use enclosed radiator systems for cooling, similar to an automobile. Generally, liquid-cooled engines are used on larger kW generators due to the larger engines required for the higher power output.
Since 1959, Generac has been designing and manufacturing backup power generators for residential, commercial and industrial applications. We have grown to be the world’s largest provider of residential backup generators, selling five times as many generators as all of our competitors combined. Generac’s broad product line is available through the industry’s largest network of independent generator dealers, retailers and wholesalers.
An automatic backup generator is a back up electrical system that operates whether you are home or away. Within seconds of an outage, it automatically supplies power directly to your home’s electrical circuit breaker box. After utility power returns, the generator shuts itself off and waits for the next outage. It operates on natural gas or liquid propane gas and sits outside just like a central air conditioning unit.
During a utility power outage, an automatic backup generator provides numerous advantages over a portable generator:
  • The American Red Cross recommends permanently installed backup generators as a safer way to provide backup power to a home than a portable generator.
  • With an automatic backup generator properly installed outside, your home is protected from deadly carbon monoxide poisoning that is a much greater risk with portable generators.
  • Running on the home’s natural gas or LP fuel supply, it is less expensive to run than gasoline and does not need to be refilled.
  • They start automatically within seconds of a power outage, and eliminate the need to haul a portable generator outside or run extension cords throughout your home.
  • They provide protection 24/7, whether you’re home or away, and they turn themselves off when utility power returns, so there is no need to monitor the unit during an outage.
ENERGY STAR is a program that was created by the US Environmental Protection Agency (EPA) to help businesses and individuals make energy efficient purchases. This program places the ENERGY STAR label, a small blue and white logo, on items that meet superior energy efficiency standards. This label provides an easy way for consumers to identify quality, high efficiency products. For more information about the Energy Star program, please view the Energy Star website at www.energystar.gov.
R-410A is the common name for a hydro-fluorocarbon (HFC) being used as a refrigerant in the HVAC industry. Chlorine-free R-410A is the replacement refrigerant for R-22 by HVAC manufacturers. At the beginning of 2010, the use of R-410A refrigerant was required for all new equipment.
R-22 is the common name for hydro-chlorofluorocarbon (HCFC). R-22 has been used as a refrigerant by HVAC manufacturers for over 40 years, but studies in the past decade have shown that HCFCs contain chlorine, an ozone-depleting agent. For this reason, the United States Clean Air Act set a target date for January 1, 2010, on which HVAC manufacturers ceased the production of products that use R-22.
HSPF is the abbreviation for the Heating Seasonal Performance Factor. This factor rates the efficient operation of the heating portion of the heat pump. As the HSPF increases, the unit functions at a more efficient level. New units in the United States have HSPF ratings from 7.0 to 9.4.
AFUE is the abbreviation for Annual Fuel Utilization Efficiency ratio. AFUE is used to rate furnace efficiencies by dividing the ratio of heat output by heat input. This measurement describes how well fuel, gas or oil is consumed to produce heat by a furnace. As the AFUE rate increases, the efficiency of your furnace also increases, lowering your fuel costs. Furnaces manufactured in the United States are required to have at least an 80% AFUE.
Do the basics
  • HVAC systems are complicated networks of machinery that should be serviced by a certified professional. However, if your HVAC system seems to be malfunctioning, you can try a few basic steps, which may correct your problem, prior to calling a service professional. If you do not feel comfortable performing any of these tasks, however, do not hesitate to call an HVAC contractor.
  • Disconnect and reconnect your indoor and outdoor switches.
  • Make sure your circuit breakers are in the ON position.
  • Make sure your filters are clean.
  • Open supply and return vents and make sure they are unobstructed.
  • Check the settings on your thermostat.
  • Make sure the system switch is on the appropriate COOL or HEAT setting.
It’s all about variability
  • Humidity levels can be reduced by using a variable-speed furnace or air handler as part of your HVAC system. Variable speed units run longer, at lower speeds, allowing air to constantly circulate against the cooling coil and remove more moisture.
  • Variable-speed motors also use less electricity than regular motors, reducing your energy costs.
Air movement from point A to point B
  • A heat pump is a device used for either the heating or cooling of a space by transferring hot and cold between two reservoirs.
  • A heat pump can act like an air conditioner, transferring heat from inside to out, or like a heater as it transfers exterior heat to the interior. A winter day with a temperature of 32º Fahrenheit still produces enough heat to warm a space when the air is transferred by heat pump.
You may have options based on your home’s design
  • The system can actually be located in several different places. A system with up-flow application might be located in the basement, while a system with a horizontal application may be found in your attic. A self-contained, or single package unit, could be located outside on a slab or on the roof. Your garage could house an up-flow, down-flow or horizontal application system.
It depends…
  • It is generally a good idea to replace the indoor coil if you are also replacing your air conditioner or heat pump. There is a correlation between the efficiency of your heating or cooling system and the performance of the indoor coil and changing out the current indoor coil for a new one may be critical to optimizing the performance, the efficiency and the savings potential of your new system.
Proper maintenance is key
  • Maintenance and service play a key role in the life-cycle of a heating or air conditioning system. If all recommended maintenance and service actions are taken, an air conditioner can last 12 to 15 years and a gas furnace 20 to 25 years.
Start with a detailed inspection
  • To install the most efficient HVAC system in your household, a detailed inspection should first be performed by your installation contractor.
  • The inspection by your contractor should include, as a minimum, the inspection of your home’s duct-work, insulation, refrigerant piping, electrical service, wiring, thermostat, condensate piping, flue piping, flue terminations, chimney liner, slabs, filter, driers, registers, grills, drain pans and evaporator coil.
It’s all about duct-work
Putting a new system in a home that has not had central air and heat before will require the installation of duct-work, insulation, refrigerant piping, electrical service, wiring, thermostat, condensate piping, flue piping, flue terminations, chimney liner, slabs, filter, driers, registers, grills, drain pans and evaporator coil. Beyond equipment, the most important component installed with a new system, however, is the duct-work. Duct-work is composed of two parts, supply and return. Supply duct is attached to the outflow of the new system, delivering air to each zone in a home. The amount of air reaching each zone is determined by the size of supply duct-work connecting it to your system. Your dealer will help you determine the size of all the supply duct-work in your home. The second part of the duct-work, the return duct, attaches to the inlet of the new system and draws air out of the spaces to be heated or cooled. Attached to the return duct is the filter. The filter should be placed as near to the furnace or air handler as possible. Duct-work can be either fiberglass or metal and must be properly sized in order to evenly distribute the proper amount of air to each room.
Factors affecting the size of your new system include the climate in your region, humidity levels, the number of windows in your dwelling, total square footage of your home, the direction your home faces, the number of heat-producing appliances in your home, the type of insulation you have and the number of people that live in your residence. Kelley Brothers can perform the proper calculations to determine the appropriate heating or cooling unit for your home and lifestyle.
Get the facts from an expert
There are many heating and air conditioning systems to choose from today. As an Amana® dealer, Kelley Brothers can draw on a vast degree of heating and air conditioning knowledge and experience to help you decide on the system that best fits your specific needs. The size and age of your home, as well as the number of rooms, climate, local and regional utility costs, and utility incentive/rebate programs are all factors that will affect the functionality and, therefore, selection of your system. Amana dealers, utilizing the latest technology, consider all these factors while assisting you in choosing the best system for your home. Consumers seeking to replace an existing system often choose a new unit with equal or higher efficiency ratings compared to their previous system. Replacing a unit that is 10- to 15-years-old may reduce natural gas or electricity costs by 30 to 50%. Contact Kelley Brothers to help determine initial cost, warranty protection, service options, maintenance options, operating cost and proper installation.
Efficiency and cost savings
At Kelley Brothers, we realize that purchasing a heating or air conditioning system is no small matter. However, if your existing system is old, in need of repair or simply inefficient, purchasing a new unit, one which can be as much as 60% more efficient than a system purchased just 10 years ago, can offer long-term benefits. Rather than continuing to pay for ongoing maintenance and costly monthly bills, invest in a new system today that will save you money for years to come.
