Product or service reviewed: fixing bathroom faucet and toilet

Gab and Dale came and fixed these items for me. They corrected some issues that I was unaware of. They are not only skilled plumbers but their manner is very comforting. Workers such as Gab and Dale are part of the reason that I use DeMelo. I also want to comment on Cathy. She is always so helpful and pleasant to work with.

Product or service reviewed: Oil Burner Repair / Tune Up

I called DeMelo early in the morning on a Monday after having issues with our oil boiler over the weekend. They sent a tech out a couple hours later who was able to determine the issue and make the repairs quickly. The tech explained what parts were being replaced and even provided us a detailed invoice of parts used and issues found. Excellent service.

Great guys! Came to see the job situation. Did not over talk the job details. We agreed to proceed, they gave me a timeline for delivery of heating and cooling equipment to my house, and the timeline, for the start and finish dates for the entire installation. They did, what they said they would do! That is HUGH! That in my book, is exceeding customer expectations!! If you are looking for a local guy to handle all your Heating, Cooling and plumbing needs, you just found them- DeMelo Plumbing, Heating & Air Conditioning. Angelo

AC Installation


Product or service reviewed: Air conditioning

Our home was being renovated. The new hardwood floors were about to be installed, during the hot, muggy July. new turned on our old central AC unit and...nothing! The people that did our new duct work could not come for 2 weeks, being that it was in the middle of a heat wave. On a whim, I called Demelo. Diana answered the phone and took care of everything from that point on. She explained to me what we needed, how much , and when. Within 2 days my house was cold, floors were getting put down, and the quote from the other "place" was more money by far!

I really needed someone to check out my older central air conditioning unit. To make matters worse, I was out of state. I needed someone who could handle this all by phone. I tried another local service but the best they could do was 'put me on a list'. I called DeMelo, left my info with the answering service, and started to sweat. Incredibly, the woman at the office called me back in very short order. We talked, she understood the situation, and we set up an service call. The next morning the tech was on-site. He inspected the unit, diagnosed the problem; and the solution, and promptly called me to relay his findings and get my OK to proceed. The whole problem was resolved very quickly and for a VERY reasonable price. They are a very well tuned combination of professional and personalized service. Would highly recommend.

We wanted to express our great gratitude to you for fitting us into the schedule on Monday and fixing our air conditioner in one day. It is hard to find such good service and we wanted you to know how thankful we are.


Dear Richard,

A little note of thanks to your company for the fast, excellent service in fixing my air conditioning. Billy, the tech, was most kind, smiling, and so efficient. He is truly an asset to your company.

Thank you again,


My wife and I would like to commend you and your employees like Dave, your HVAC technician. From the date/time the work was started until the date/time the work was complete, Dave was very respectful of our home and our pets, he informed us of each phase of the work from installing of new duct work to the new furnace and A/C condenser. Your professionalism and the professionalism of all of your employees not only brings credit upon yourself but to your company.

Thank you,

Beverly & John
