Generators

When the power goes out, you can calmly sit back and relax while your automatic standby generator clicks on to restore power to your entire household, including major appliances and your HVAC system.

Residential Standby Generator

The standby generator is a permanent installation wired directly into your home’s electrical system to provide the amount of electrical power necessary to run the vital systems in your home—or your whole home if you wish. Most standby generators run from natural gas piped directly from the municipal supply, so you will not have to worry about refueling the generator. Standby generators are also safer than portable generators because they are located outside a house and present no danger from toxic exhaust gases. They can power the electrical needs of the whole home and will activate as soon as required, without you needing to wade out into bad weather conditions to switch it on.

All standby generators we offer are automatic. They are wired directly into the electrical system of a home, but they will sense when power from the grid stops and then turn themselves on immediately to begin to supply the house with the electrical power necessary to run the systems that must stay on during a blackout. If your automatic standby generator received professional installation originally, it will deliver the right amount of power for your needs, whether you only require a few lights and the heating system working, or if you want a comprehensive backup for the entire house.

Generac Guardian® Series kicks in within seconds of determining power loss – automatically – and runs for as long as necessary until utility power returns.

The pre-packaged Protector™ Series backup generators run on diesel fuel and are more cost-effective than many competitive diesel-fueled generators.

How does a residential backup generator work?

A Generac home backup generator senses a power outage, turns on automatically, and delivers backup power to your home. It will run until utility power returns – whether that’s two hours or two weeks.

Utility power is lost

Perhaps it’s a storm. Maybe it’s an equipment failure. In any case, the electricity you depend on is suddenly gone.

Commercial Standby Generator

Commercial Standby Generator

Customers tend to rely on businesses of all types during power outages, and it’s important that you’re able to deliver when you lose power. 

Losing electricity for your business: you don’t need anyone to explain that this is a major problem. No matter the kind of company you run, it will mean a loss of productivity and a halt to business. You will want to find the best way possible to protect your company from such problems. If you provide important services to the community, keeping your workplace operating during a blackout will help out a great many more people beyond your company. Finding ways to stay open will also help you get an edge on any competitors.

It’s essential that the wattage of the generator matches the needs of your building. Too little power and you won’t manage to keep the company up and running. Too much and you could have damaged circuits and a broken control panel—you’ll end up with no power plus repair costs.

It is also crucial that your business remains up to local electrical codes; only licensed electricians have the knowledge to make sure that your generator installation doesn’t violet the code. 

You can get all your needs met with the installation of a quality commercial generator. The assurance of an effective generator will give you as a business owner during the stormy conditions that may lead to power outages is worth the installation costs alone.

How do we make it work

Installation

If you want a generator that will be as reliable as it is efficient and powerful, then it all starts with your generator installation. No matter how good your equipment is, it won’t matter much without professional installation.

A generator will use a back–up fuel source—natural gas, propane, diesel, etc.—to deliver electrical power into your home when power from the grid goes out. You can choose how much power your home needs to continue to function. For example, you may only require a few necessities: a couple of lights, the refrigerator so food won’t spoil, and power for the air conditioner or heater (keep in mind that even gas-powered heating systems must have electricity for their components to run). But you may also have additional needs, such as medical equipment, that must continue to work through an outage. The choice is up to you. With the proper system installed to back–up your electrical power, you can enjoy all of the standard comforts of your home until the municipal power is restored.

Skilled technicians will properly size the generator for your home. They will work with you to find out what your power needs are during a blackout, and then locate a model and size of generator that will deliver that level of wattage without overloading your system. The technicians will then perform the installation work so that your new generator hooks correctly into your home’s electrical system and to its own power supply. Because many generators use natural gas, you should never attempt to work on one on your own because of the risk of toxic gas exposure. Leave everything to professionals.

Maintenance

It’s important to keep an eye on your generator during its years of service to make sure that it is always there when you need it to be. The best way to go about this is routine professional maintenance.

It allows the system to perform its most important task: giving you the reassurance that your home and family will make it through any power outage in comfort and safety.

In addition to providing peace of mind, routine regular maintenance for a generator will help the system run at its most efficient. A generator that is wearing down and has loose connections will drain energy much faster and cost more to run. If store fuel for your generator, such as propane, you don’t want to have the system drain the fuel faster than it should. A regular tune-up and cleaning will see that your generator will operate at maximum efficiency whenever it turns on.

Finally, maintenance will determine if an older generator requires replacement. Sometimes a system can age to the point where it is no longer worthwhile repairing and maintaining it. If this is the case, the technicians will help you schedule a replacement installation.

Repair

It’s critical that you keep an eye on your generator during operation to take into account anything out of the ordinary. While some problems may be obvious, others are far more subtle; all require a professional’s expertise and experience to diagnose and solve. 

While you may be tempted to repair your generator all by yourself, this can lead to greater problems that you may be prepared for. Only a professionally trained technician can adequately diagnose your generator to assess what’s wrong with your equipment. You don’t want to rely on guesswork and an internet video when it comes to restoring your whole house generator. Both electricity and natural gas are potential hazards, and you also want to make sure that the job is done quickly as well as correctly.

If you find that your generator makes a strange sound, or fails to operate properly, then it’s imperative that you give us a call. Our generator repair service is responsive and comprehensive.
