Pierce Plumbing and HVAC, with over a decade and a half (15 years now) of trusted service, proudly offers comprehensive plumbing, heating, HVAC, and electrical solutions to homeowners and businesses in the Leominster and Worcester County areas.
"Unfortunately I had a terrible experience with them especially the owner. He schedules time to meet at 12 to review my project to add gas line. He never showed up. I arrived at 12:03 to meet him at the property and called the company to follow-up if they were on the way. He said he arrived at 11:50 and waited 5 minutes and left. When asked why he left so early and didn't even give curtousy of a 5 to 10 minute wait. He said he doesn't wait any time if he gets there early it's my problem I wasn't there even though we had scheduled for noon. He was so rude and said he gives no one curtousy to wait any minute and can't turn back around. In my opinion he never went to my house and lied and was rude. I told him I didn't need his business because if that's how he treats potential clients I can only imagine the type of service he will provide. Very RUDE, unprofessional and someone I don't recommend doing business with."

Generator installations FAQs
Installing a whole-house generator costs about $5,000 on average. Prices range from $1,550 to $8,500, depending on size, brand, fuel type, and assembly. The size of your whole-house generator is the most significant cost factor, with large homes with high energy demands costing the most to power. Types of whole-home generators include:
Portable generators with 1kW–7.5kW capacity: $500–$2,000
Partial generators with 9kW–20kW capacity: $2,000–$6,300
Whole-house generators with 22kW–48kW: $5,000–$18,000
When maintained properly, a whole-house generator can last up to 20 years. Costs to maintain and repair generators vary by location and type of generator, but you can expect to pay about $150 to $300 per year for annual generator maintenance checks. An experienced generator service technician will inspect your generator’s engine filter, starting mechanism, fuel, lubrication, and coolant levels to keep your generator in good working condition for as long as possible.
When choosing the right size generator for your needs, consider a few items to help calculate the wattage you’ll need. Start by determining which household items and appliances you want to power, and then add the wattages together. Check out the wattage of these essential appliances:
Refrigerator: 600 watts
Large dehumidifier: 700 watts
Large window air conditioner: 1,400 watts
Water heater: 3,000 watts
Running home appliances like these requires a partial or whole-house generator. A portable generator may be enough to power your home if you only plan to keep a refrigerator and freezer running.
Here’s what you can run with different wattages and types of generators:
Portable generator:
2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers.
4,000 watts will keep two large appliances operating and a few smaller devices.
8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.
Partial to whole-house generator:
20,000 watts and above will make it seem like your home’s power is still on.
The value of installing a whole-house generator is that your home has guaranteed power, even if the power grid in your area is down. Whether a whole-house generator is worth installing in your home depends on how often you use it, your home’s location, and your lifestyle. For example, installing a whole-house generator is likely worth it if you:
Experience frequent or prolonged power outages
Work from home
Store a lot of cold food
Have a sump pump
Have a pump for well water
Use electronic medical devices
Live in a climate requiring heating or cooling
