"My installer Samuel was top notch, very detailed, pleasant, answered all my questions. Excellent representative. The only problem I had was miscommunication on their end as I was told available payment options and Samuel was told another. Did not affect installation or quality of work at all."

"The seal on the bottom of my garage door had dry rotted. I hired someone to replace it. They bought the part but could not install it. We were expecting a lot of rain, so I needed it done as soon as possible. I called Mach 1 Mechanical. Jason came out the same day. He was very professional and courteous. Jason determined that the part I had was not the correct part. Since it would take time to get the correct part, Jason decided to modify the part I had. He successfully modified and installed the part. There has been zero water entering under the door. Jason went the extra mile and I could not be happier with the job he did. He did it at an excellent price. I would hire him again in a heartbeat."

Generator Install questions, answered by experts

Many services include assembling the unit and securing it in the window. Confirm with your provider.

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.

It might seem counterintuitive, but installing a generator transfer switch will save you money in the long run. While you’ll have to pay between $400 and $2,500 to have the transfer switch installed, you’ll recoup that amount later on when you don’t have to pay for expensive repairs to your appliances, devices, and electrical system that may have burned out, overloaded, or stopped working due to a sudden loss of power or an incorrect hook up of a generator to your home. 

With proper maintenance, a whole-house generator can last between 20 and 40 years. The specific lifespan depends on how often and for how long the generator is used, and some models may have their life expectancy rated in hours of operation. To maximize its lifespan, expect to spend around $150 to $300 per year for annual maintenance checks from a qualified technician. During these checks, a technician will inspect the engine filter, starting mechanism, fuel, lubrication, and coolant levels. Consulting your installer and choosing a low-impact fuel like natural gas or diesel can also help ensure your generator lasts as long as possible.

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.
