"If you're looking for this type of service, don't look any further. IMO this company is the best in New England. We have used their services for hot water heater and gas dryer installs, and now ductwork cleaning. Ben and Dominic did a great job and were very conscientious of our home while doing their work. The photos of before and after the cleaning were amazing and my wife and I can feel the difference in the air quality just after one day. You can't go wrong with Hall's. Don and Nancy"

Plumber NH at Paul The Plumber offer 100% Customer Satisfaction! Simply put, we stand behind what we do. All of our repairs are guaranteed for 2 full years parts and labor. We service every make and model.

"Rating: 1/5 Stars Title: Aggressive Upselling and Misleading Technical Advice ? Beware I recently had a technician (Matt M) from Paul The Plumber come out for a simple warranty repair on my water heater?s igniter. While the warranty repair itself was completed, the rest of the visit was a masterclass in aggressive and dishonest upselling. The technician presented me with estimates totaling nearly $1,800 for "Peace of Mind" replacements that were completely unnecessary. The Main Issue: Misleading Code Requirements Most concerning was the technician's attempt to charge me $639 to replace my existing flexible gas lines with hard piping. He claimed that "gas code requires" refitting the water heater to 1/2" iron piping and that my current setup could cause pressure issues if other appliances were running. This is factually incorrect. Standard flexible gas connectors are rated for significantly higher BTU loads than a residential water heater draws (often up to 180,000 BTU, while a tan"

Air Duct Cleaning questions, answered by experts

You can do some cleaning yourself by removing vents covers and grabbing your vacuum to suck up visible dust. However, professional duct cleaning companies have the tools for more thorough cleaning deeper inside the system. It is worth bringing in the experts for a healthier home.

If you don’t clean an evaporator coil, you’ll likely experience many unpleasant results, including higher energy bills, mold and mildew buildup, ice or frost buildup, a clogged condensate drain, and more. In addition, you’ll be dealing with an overall uncomfortable home and frequent HVAC breakdowns, plus your HVAC will continue to perform inefficiently.

Yes, dirty air ducts restrict airflow, reducing your HVAC's efficiency. This forces your system to work harder, increasing energy costs and wear and tear on your HVAC. Reduced airflow leads to uneven heating or cooling, seriously reduced indoor air quality, and can potentially trigger allergies or respiratory issues.

Air duct cleaning scams are, unfortunately, so common because the industry is largely unregulated, and technicians don’t need to hold licenses in most states. It’s also easy for scammers to use scare tactics to claim that your indoor air is potentially unsafe, which makes the service an easy sell. Finally, most homeowners don’t have access to their hidden HVAC ducts and can’t check on issues themselves, so it’s easy to claim that there’s mold or debris build-up in there and have it go unchecked.

Dirty air filters are the likely culprit. You should swap them out every month or at least every quarter. If you’ve kept on top of those filters and still notice a rapid accumulation of dirt, it could indicate that the ductwork requires a thorough cleaning. It’s also probably time to schedule that HVAC system inspection.
