"We had a furnace installed by Harp on July 8th 2024 after it being diagnosed by their technician as to the reason our ac system was not functioning properly. That’s when our troubles with Harp began. The installation was not done properly, we needed 3 service calls to get the ac to work properly. The installers were sloppy. We cleaned up screws and wire and parts from the old furnace for weeks. When heating season began we noticed that the humidifier installed with the furnace was not operating. We scheduled an appointment to have it repaired and they called the day of the appointment and told us they couldn’t come that day and we had to reschedule, so reluctantly we did. They finally came and repaired it. From what the technician told me it was not wired properly. On January 21st 2025( the coldest night of the year) the furnace stopped working. We called Harp to get someone to come to repair it as we had no heat in below 0º weather I was told the best they could do is to come the next day between 2 and 6 pm. I tried to explain that this was an emergency but to no avail. I called my local oil company and they were at my door within 30 minutes( which I would’ve expected from the company who sold us the furnace) the repaired it quickly and told us that one f the wires on the control panel was not attached properly. It cost me $300. I would NOT recommend Harp to anyone. They are not reliable and do not stand behind their promises of service 24/7. Stay as far away from this company as possible. We are sorry we ever started with them."

FAQs for generator installation projects in Wallingford, CT
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
