"My son needed assistance in getting his Cadillac through emissions. I went to a lot of places. They all wanted at least 3 times the value of the vehicle. I went on the DMV website and searched for mechanics with a 100 percent pass rate. I found Bryden's and found good reviews. Went in. Met a mechanic that was friendly. Explained everything and laid out the options and made it downright affordable. They did the repair and physically took it though emissions. Specifically track down an intake leak on a 2001 Cadillac Seville STS. Not an easy task. Job done. Very pleased with the service. I highly recommend them to not just do emissions but do other repairs."

Generator Install questions, answered by experts

When properly maintained, natural gas generators can last a long time, as much as 20 to 40 years. They have relatively few needs compared to generators with other fuel types. However, the generator’s lifespan ultimately depends on how often the generator is used and for how long it’s left running.

Yes, installing a generator usually increases your property value because buyers are getting the added peace of mind knowing they’ll be able to maintain power through blackouts. In most cases, you should see close to a 100% return on investment (ROI). Keep in mind that home generators usually need a permanent foundation, and installing a concrete slab will likely raise your property taxes slightly.

No, this is extremely dangerous, often illegal, and you should never attempt it. If you connect your generator to your home without a transfer switch, the generated power can backfeed, essentially flowing back into the utility lines. Backfeeding exposes a significant threat of fatalities or harm to you and utility personnel, in addition to jeopardizing the structural integrity of your home.

Yes, natural gas generators can work without electricity. Natural gas generators are a common type of backup or whole-house generator that operates when the electrical grid isn’t working. The trick is using a transfer switch (which usually needs to be installed with the generator) that safely switches the home electrical system from the power grid to generator power when needed.

DIY is possible for basic setups. Professional installation ensures safe and proper electrical connections.
