Trusted Generator Specialists in Chattanooga, TN
CERTIFIED GENERATOR SIZING, INSTALLATION & SERVICING
KEEP YOUR HOME POWERED THROUGH ANY OUTAGE IN CHATTANOOGA
A standby generator installation is not purely an electrical job. It involves load calculation, a fuel supply, a gas line, a concrete pad, a transfer switch, and permits. At Metro Plumbing, Heating & Air, we handle every part of it in-house across Chattanooga, TN, rather than coordinating three separate contractors.
That matters more than it sounds. We already run gas line work and HVAC systems for Chattanooga households, so we know how to size a generator that will actually carry your air conditioning on a July afternoon, and we can run the gas supply ourselves rather than subcontracting it.

Chattanooga’s Trusted Home Service Team Since 1989
For over three decades, Metro Plumbing, Heating and Air has kept Chattanooga households running through whatever the Tennessee Valley has thrown at them. We know which neighbourhoods lose power first, how long restoration typically takes, and what it costs a family when the freezer thaws or the sump pump stops. Standby generators are a natural extension of the work we’ve done here since 1989.
LICENSED GENERATOR TECHNICIANS IN CHATTANOOGA, TN
Our Generator Services
Metro provides complete standby generator services for homes and businesses across Greater Chattanooga, from the first load assessment through to annual servicing. Financing is available on installations, so a generator doesn’t have to be a single large outlay.
Whole-Home Standby Generator Installation
A permanently installed standby generator sits outside on a concrete pad, connects to your natural gas or propane supply, and starts automatically when it detects an outage. No fuel cans, no extension leads, no going outside in a storm. We handle site selection, the pad, the set, and full commissioning.
Generator Sizing and Load Assessment
Undersized generators fail under load and oversized ones waste money. We calculate your actual demand, including the start-up surge from air conditioning and well pumps, then recommend a unit that matches. You also choose whether to back up the whole house or just essential circuits.
Gas Line Connection and Fuel Supply
A standby generator needs a correctly sized gas supply, and an undersized line is one of the most common causes of poor performance. Because we already run gas line work across Chattanooga, we size, run, and pressure-test the supply ourselves rather than bringing in a third party.
Automatic Transfer Switch Installation
The transfer switch is what makes a standby system automatic. It detects the outage, disconnects your home from the grid, and starts the generator, usually within seconds. It also prevents backfeed onto utility lines, which is a serious hazard to line workers. We install and configure it correctly.
Generator Repair and Diagnostics
A generator that hasn’t been serviced often fails at the worst possible moment. We diagnose and repair starting faults, battery failures, fuel supply issues, controller problems, and transfer switch faults, including on units we didn’t install.
Generator Maintenance and Testing
Standby generators need regular attention: oil and filter changes, battery testing, coolant checks, fuel system inspection, and a load test to confirm the unit will actually carry your home. We provide scheduled servicing so yours is ready before storm season rather than after.
At Metro Plumbing, Heating & Air, we install standby generators the way they should be done, with proper load calculations, a correctly sized gas supply, and full commissioning. Whether you’re protecting a home office, medical equipment, or simply your family’s comfort, contact us today to discuss generator installation in Chattanooga, TN.
WHY CHATTANOOGA HOMEOWNERS INSTALL STANDBY POWER
What a Whole-Home Generator Actually Protects
Your Home Runs Automatically
A standby generator starts on its own, usually within seconds of an outage, whether you’re home or away. There’s nothing to set up and nothing to refuel. If you travel, or if an outage hits while you’re at work, the system handles it without you.
Food and Medication Stay Safe
A full freezer and refrigerator represent hundreds of dollars of food, and a multi-day outage means throwing all of it away. For households storing insulin or other temperature-sensitive medication, keeping the refrigerator running isn’t about convenience at all.
Sump Pumps Keep Working
The storms that knock out power are the same storms that fill basements. Losing a sump pump during heavy rainfall is how outages turn into flood damage, and it’s one of the most expensive consequences of an extended outage in this region.
Well Pumps and Water Supply
Households on well water lose their entire water supply the moment power goes out. That means no drinking water, no washing, and no flushing. For properties across North Georgia and the outlying areas we serve, this alone justifies standby power.
Heating and Cooling Stay On
Chattanooga summers are genuinely dangerous without air conditioning for vulnerable household members, and a winter outage risks frozen pipes. A correctly sized generator carries your HVAC system, which is exactly the load most undersized units fail to handle.
Security, Work and Communication
Alarm systems, cameras, garage doors, internet, and home office equipment all stop with the power. For anyone working from home or relying on powered medical devices, an outage becomes considerably more than an inconvenience.

Frequently Asked Questions
GET ANSWERS TO COMMON QUESTIONS ABOUT GENERATORS IN CHATTANOOGA, TN
Should I get a standby generator or a portable one?
Portable generators are cheaper and suit occasional, limited use, but they must be manually started and refuelled, run outdoors only, and typically power a handful of appliances. A standby generator is permanently installed, starts automatically, runs on your gas supply, and can carry the whole house.
What size generator do I need?
It depends entirely on what you want running. Essential-circuit backup covering refrigeration, some lighting, and a sump pump needs far less capacity than whole-house coverage including air conditioning. We calculate your actual load rather than estimating from square footage.
What does a whole-home generator cost?
Cost depends on the unit’s capacity, the complexity of the gas supply run, the distance to your panel, the transfer switch specified, and any site work needed for the pad. We provide a detailed written quote after assessing your property, and financing is available.
Can I install a generator myself?
No. Standby generator installation involves gas line work, a connection to your service panel, a transfer switch, and permitted inspection. Incorrect installation risks gas leaks, fire, and dangerous backfeed onto utility lines. This work requires licensed trades in both Tennessee and Georgia.
Can I run a portable generator in my garage or basement?
Never. Portable generators produce carbon monoxide in quantities that can be fatal within minutes, and CO poisoning kills people during outages every year. They must run outdoors only, well away from doors, windows, and vents, and never in a garage even with the door open.
What fuel does a standby generator run on?
Most residential standby generators run on natural gas or propane. Natural gas is generally preferable where a supply already exists, since there’s no tank to refill and no fuel to run out of during an extended outage. We’ll advise on the best option for your property.
How does an automatic transfer switch work?
It continuously monitors utility power. When it detects a loss, it safely disconnects your home from the grid, signals the generator to start, and transfers your circuits across, usually within seconds. When utility power returns it transfers back and shuts the generator down.
Do you service generators you didn't install?
Yes. We diagnose, repair and maintain standby generators regardless of who installed them. If you’ve inherited a unit with a property or your previous installer is no longer available, we can take over its servicing.
How often does a standby generator need servicing?
Annual servicing is the minimum, ideally before storm season. That covers oil and filter changes, battery testing, coolant and fuel system checks, and a load test. Batteries are the single most common reason a generator fails to start when needed.
