Generator Installation & Service

Generator Installation

Backup generators provide a reliable source of power during an outage or emergency. They can be powered by diesel, gasoline, natural gas, propane, and solar energy. Installing a backup generator requires careful consideration and planning to ensure the best result for your needs.

The first step in installing a backup generator is to have the generator professionals at Total Mechanical Systems perform an analysis of your energy needs, and determine which generator is best for you. Factors to consider when choosing a generator include the type of fuel it uses, size, noise level, voltage requirements, and cost.

Once we have determined the best generator for your situation, our expert electrician will professionally install it for you. Location is an important factor in generator installation; it should be placed in a well-ventilated area away from windows and doors. It is also important to do regular maintenance on your generator to ensure it runs properly and safely.

Backup generator installation is an important investment in your energy reliability. A generator can provide peace of mind that you will have access to electricity at all times, even during emergency situations. With careful consideration and planning, you can ensure the best result for your needs.

We are here for all of your home comfort needs!

Generator Installation, Service & Repair in Connecticut FAQs​

Most whole home generator installations take one to two days to complete, depending on the complexity of your electrical setup and whether additional site preparation is needed. Our team will assess your home during the initial consultation and give you a clear timeline. We handle everything from permitting to final testing to ensure your generator is ready when you need it.
The right generator size depends on what you want to power during an outage and your home’s total electrical load. Our technicians will perform an energy analysis to determine your specific needs, whether you want to run essential systems like heating and refrigeration or keep your entire home operational. We’ll recommend a properly sized system so you’re not overpaying for capacity you don’t need or underpowered when an outage hits.
We recommend having your generator professionally serviced at least once a year to keep it reliable and ready for emergencies. Regular maintenance includes testing the transfer switch, checking battery health, changing oil and filters, and running performance checks. Routine service helps prevent unexpected failures and extends the life of your system.
Natural gas generators connect directly to your home’s gas line for unlimited fuel supply, while propane generators use stored fuel in a tank that needs periodic refilling. Natural gas is convenient if you already have service, but propane can be a better option in areas without gas lines and typically has a longer shelf life. Our team will help you choose the best fuel option based on your property and local availability.
Yes, whole home standby generators are designed to start automatically within seconds of detecting a power loss. The transfer switch senses when grid power is interrupted and signals the generator to turn on, then seamlessly switches your home to backup power. Once utility power is restored, the system automatically transfers back and shuts down the generator.
