"I posted I needed a window AC unit removed and this company was the only one to respond. The owners wife responded with in an hour, told me they would be at my house 3 days later. I responded, can you give me an estimate of how much it would cost. She responded, sir there is no charge, we just like helping out the community. I was shocked. Being on a fixed income. Craig arrived, removed the AC, and I started asking questions about mini split systems. He was here at least an hour explaining how they worked and my options. I have now ordered my new AC slash heatpump, to be installed. There was no pressure, just me asking questions and I loved what he had to say. Perfect gentleman."

"There team did an amazing job, moving the dryer out, replacing tubes as needed, and going into attic, and outside to clean the vents, as well as thoroughly cleaning the inside of the dryer. Moved everything back perfectly, and left the place spotless. Dryer functioned 100x better."

"The 2 men who did the work did a very good job.  My duct work had never been cleaned, so they had to cut a piece out of the return filter unit to clean it.  Some of my vent covers  had been painted on, so removing the nails was time consuming.  They did a very good job and made recommendations about the duct work that I plan to follow (venting the dryer to the outside rather than into the garage, getting a dehumidifier for the bedroom in the basement).  They were professional and helpful.  Hiller Plumbing recommended that I get the vents cleaned and their estimated price was $900 and that did not include the sanitation, so I think that I got a very good deal!

"All I needed was a replacement for a broken, rusted toilet flange that was set in cast iron. The technician was very professional, and the quality of the work was excellent—I could never have done it myself. I gave 4 stars instead of 5 only because of the cost ($650). To be fair, I didn’t get any other estimates, but it did seem a bit expensive for a job that took only one hour."

"We own a home in Gloucester that we rent out during the high season. During the hottest week of the summer, two of our central A/C units broke down and we needed to replace them fast. I called ten different A/C companies on a Sunday night—and was amazed that I reached SEASHORE COMFORT SOLUTIONS directly. Sarah sent out someone from their team the next day to do a diagnostic; we ended up replacing the two units within days of that first visit. Every time I called the office, someone answered. Every time I wrote to SEASHORE COMFORT SOLUTIONS, I received quick responses, clear answers and very courteous service. They deserve FIVE STARS every time. When the units were installed, the tech called me about the wall mount placement and then again to tell me they were leaving. SEASHORE COMFORT SOLUTIONS was so easy to work with and I'm relieved to know that they are nearby and ready to help when needed. Thank you to Sarah, Rich, Frank and everyone on the SEASHORE COMFORT SOLUTIONS team!!"

"We were very pleased with the communication and the outcome of our project. We have an old home with some older piping. Finding someone that works on steam boilers is tough. When they looked at the install, they explained what needed to happen clearly deand unrstandable."

FAQs for ducts & vents installation and replacement projects in Dover, NH

Return air vents aren't required in every room, but proper placement is essential for system efficiency. According to industry standards, you'll need one return vent for every 100 to 150 square feet of living space. Ideally, each room would have its own return vent, especially larger rooms exceeding 100 square feet. 

Without adequate return airflow, your HVAC system works harder, energy costs increase, and comfort decreases. A professional assessment can determine the optimal number and placement of return vents for your specific home layout.

Signs that your home needs additional return air vents include rooms that feel consistently stuffy, noticeable temperature variations between rooms, doors that slam shut when the HVAC system operates, or unexpectedly high energy bills. Excessive dust accumulation around supply vents can also indicate inadequate return airflow. 

If you experience these issues, consulting with an HVAC professional can help determine if adding return vents would improve your system's performance.

Supply vents deliver conditioned air into your living spaces, while return air vents draw room air back to your HVAC system for reconditioning. Supply vents push treated air into rooms, while return vents pull air from rooms back toward your heating and cooling equipment. 

Both components are essential for proper air circulation and system balance. Without sufficient return capacity, your HVAC system may experience pressure imbalances that reduce efficiency and comfort.

You should inspect and clean your return air vents at least once annually, according to industry recommendations. However, homes with pets, allergy sufferers, or noticeable dust buildup may benefit from more frequent cleaning. 

Regular maintenance helps maintain good indoor air quality and ensures your HVAC system operates efficiently. Professional duct cleaning, which addresses the entire system beyond just the visible vents, is recommended every few years, depending on your home's specific conditions.
