"Absolute ripoff, along with shady business practices. They were prompt and courteous, but that's about it. The technician came and had to replace a $200 part on my boiler, it took him under an hour to do the work. A simple Google search showed at least 10 places to buy the exact part, all around $200. No other parts were needed for this repair, I researched what is involved. I was charged almost $1000, including their $89 diagnostic fee just to walk in the door. So apparently it's a $600+/hour labor rate? I'm obviously in the wrong line of work. This was not an off hours emergency call either, it was a scheduled appointment in the middle of a weekday. The shadiest part of the entire thing was that on the invoice (that they email you later) they bury all the cost, it's not itemized i.e. labor vs parts cost. It just says replaced (part) = $1000. A super scummy and shady way to run a "professional" business, taking advantage of people who don't know any better. I wouldn't be surprised if they also sell used cars. Never again Gervais. You've all been warned."

"Charged $2,000 (that's right, $2,000!) to install a new sprayer faucet and soap dispenser in Boston. $1,500 went to labor, which took less than 2 hours. I'm sorry, but $750/hr is outrageous. I did pay it because I wanted to expedite solving the problem for the tenants, but I now regret as their dishwasher is not working and I suspect the plumber failed to reconnect everything probably."

FAQs for central humidifier installation and replacement projects in Northbridge, MA

Aim for indoor humidity between 30% and 50%, with the sweet spot around 45%. That range keeps mold, dust mites, and musty odors in check while protecting drywall and woodwork. Staying in the zone also helps your HVAC system run more efficiently and supports healthier air for you and your family year-round, during hot summers and cold winter months.

With routine filter changes and coil cleanings, most whole-house units run for eight to 15 years. Heavy use, poor air quality, or bargain-bin equipment can shorten that span, while a well-maintained, high-quality model often makes it to the upper end of the range. Ask your installer about recommended service intervals to get the most mileage from your investment.

It depends on your climate. Homes in cold, dry regions can often shut the dehumidifier off once winter sets in. If you live in a warm, humid area—or your house tends to trap moisture—you may need to keep it running year-round. Use a simple hygrometer: if readings stay below 50%, give the unit a rest. Just remember to restart it when humidity climbs again to avoid mold and condensation.

Dry air feels cooler, so your AC doesn’t have to work as hard. By stripping out excess moisture, the dehumidifier lets you raise the thermostat a few degrees without losing comfort. A shorter AC runtime reduces electricity use and can shave a noticeable amount off your summer power bill. Energy-efficient models further enhance those savings.

If your home is under about 2,000 square feet, a well-placed portable unit can handle the load. Just remember they’re less efficient and need hands-on upkeep—think emptying tanks and cleaning filters. If you prefer set-and-forget convenience or plan to expand your living space, a whole-house model still offers better long-term comfort and lower energy use per square foot.
