Get matched with top generator install pros in Arlington, MA

Q: Can a natural gas generator work without electricity or in a power outage?

• <div><p>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&rsquo;t working. The trick is using a <a href="https://www.angi.com/articles/cost-install-generator-transfer-switch.htm?entry_point_id=33797025">transfer switch</a> (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.</p></div>

Q: How do generator specifications and installation requirements impact the overall cost?

• <div><p>Costs depend on generator type, labor, and additional wiring or transfer switch requirements.</p></div>

Q: What size generator do I need for a 2,500-square-foot house?

• <div><p>A home that is 2,500 square feet will likely need a 20kW to 25kW generator. Consult your local generator installer to confirm the generator size needed to power your home before purchasing a new one. Be sure to consider how much power your necessary devices need to run.</p></div>

Q: What is the life expectancy of a whole house generator?

• <div><p>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.</p></div>

Q: Are natural gas generators worth it?

• <div><p>While natural gas generators are costly, they&rsquo;re a great option for standby power due to the reliability of natural gas as a fuel source. Unlike other fuels, natural gas is delivered through underground pipes, making outages extremely rare and less likely to be affected by the elements. As long as the area isn&rsquo;t prone to earthquakes, they offer an unlimited supply of natural gas that doesn&rsquo;t degrade over time or require storage in tanks.</p></div>
