"Thank you so much for coming to my rescue in a time of need! My basement was flooding, water coming in through the foundation, and I was exhausted from trying to keep up with it. You guys realized the importance of prioritizing me, and put in a sump pump to save the day. You are the best!" - Joanne Lipsy

"We've used A-1 a couple of times and are always pleased. All the cracks that have been repaired have held up beautifully and we are now enjoying a newly finished basement with no concerns about water due to the cracks!" - Brendan Kenahan

"Rich was very professional and sent his technician Andrew to do the work. Wasted no time, just stayed with it. He was very knowledgeable and indicated if there was any problems they would come back and fix them. No more leaks! It is good to know there are still companies that care and deal with the issues." - Rich B.

"A couple of weeks ago we had A1 out to do some work on the bulkhead at our home in Woodstock Valley, CT. So far we are extremely pleased with the performance of the injection, I'd say 2 days after the work we had 4 inches of rain in one evening, not a drop came in. I can sleep easier now about the decision we made last month to finish our basement, we love having the extra, dry, living space." - Ron Sanderson

Rich is a reputable and responsible businessman who we have worked with several times. His response to us is always prompt and professional. He is able to schedule appointments and provides pricing in advance of performing his service and there is no up-selling involved. We would use Rich and A-1 again and we refer him often with our complete confidence

I cannot thank you enough. What an incredible company you have. It's comforting to know that if there's another problem in the future, I know who to call!! - Barbara Salzman

"I would have to say your company is " A 1", in my book. I will see you again in the spring." - Valerie Curley

How Home Dehumidifiers Work

Joseph Coupal - Monday, June 13, 2011

The purpose of a dehumidifier is to lower the humidity of the air in your home.  Humidity is a measure of the moisture suspended in the air at any given time.  Moisture levels are higher during different seasons.  In Massachusetts, humidity levels are much higher in the summer than in the winter. 

Home dehumidifiers are mostly used to dry air in the basement or crawlspace.  These areas are prone to high humidity levels because they are below ground.  It is not uncommon for the saturated ground outside of foundation walls to cause seeping or leakage through the walls.

The condensation is what allows a home dehumidifier to work. The dehumidifier typically consists of a metal or plastic cabinet that contains a fan, a compressor, metal coils and a collection pan.  There is also a humidistat that allows you to set the level of humidity you desire within a room.

The fan draws air into the unit, and it passes over the coils.  The coils are often set up as a two-stage process.  In the first stage, the coils are very cold.  As the air passes over the cold coils it condenses and collects there.  From here the water drips into the collection pan.  As the air continues on through the unit, it hits the second stage of coils which uses the heat generated by the compressor to re-heat the air and deliver it back in to the room.  

In the meantime, the collection pan fills with water.  The shut off is triggered when the water reaches a certain level.  Sometimes, rather than a collection pan, home dehumidifiers have a fitting that can attach to a hose so that the water can run out of the unit to a drain of your choice.

Understanding the basics of how a home dehumidifier works is important so that you can determine which type of unit to buy for your home.  A high quality, low maintenance unit is the best choice for most homes.  Compare home dehumidifiers carefully before investing in them, this is an important piece of equipment.
