After the expansion tank was added and adjusted on the hot water tank my washer and dryer have to be squeezed back into place, pipes have to be pushed out of the way to make the washer and dryer to fit.

There are two Arsenaults in the business. My beef is with Dennis in Ossipee. I have 2 furnaces…read morewhich are cleaned annually and I've trusted Dennis to do the job and have been satisfied with service, so I thought, for the past 5 years. But this has all changed, and this year we discovered the filter in one furnace was filthy and clearly hadn't been touched in a long time if ever. The other furnace had a broken and unused filter on the floor. There was no filter where there should be one and the area under the blower was covered with debris. Did they clean at all? Clearly no. Did they accept a check for $450. Yes. Mobility issues prevent me from going to the basement but luckily my handy friend discovered the unused filter and investigated. Three phone calls have gone unanswered. I'm hurt and disappointed in this shabby treatment and will spread the word.
