Plumbing Technician’s Work Was Impeccable!

I heard water running on Thursday night.  Nothing in our house was turned on.  My husband did some troubleshooting and called Harriett’s Plumbing Friday morning.  Harriett’s plumbing technician came out to survey the situation.  He returned Saturday morning with all the necessary supplies, pressure tested the lines and identified the leak.  He installed all new hot and cold water lines, running them through our attic (under our insulation with pipe insulation around the new Pex lines), down the wall and through the back of our kitchen cabinets to the kitchen sink.  Our lines under our slab are now disconnected.  Your plumbing technician did a spectacular job!  I feared having to tear up my hardwood floors and have my concrete slab jack hammered.  We ended up with two holes in our ceiling and one behind our stove and the job is complete!  Your plumbing technician was such a wonderful person to work with.  He is extremely knowledgeable, listened to our concerns and performed the job with minimal “damage” to our home.  His work is impeccable!  I highly recommend Harriett’s and your plumbing technician.

Hot Water Heater – From Oil Fired to Electric

Potential new customer called; was without hot water for almost a week and wanted to convert from an oil fired water heater to an electric water heater.  Customer indicated her whole experience with Harriett’s was great, as first the old oil fired water heater had to be disconnected correctly, followed by the installation of the new electric water heater.  The customer service she received from Harriett’s from the beginning to the end was impeccable and everyone involved went above and beyond to ensure her safety.  It is great to see a company still stand by their customer service and the technicians who came out were all excellent, neat, and provided great customer service for Harriett’s.  She will be using Harriett’s moving forward as much as possible.

Friendly, Professional Technician

Your technician was friendly, professional and knowledgeable.  Checked out everything thoroughly and explained the power was not coming from our generator.  He is an asset to Harriett’s.

Like Seeing an Old Friend!

Customer of Over Twenty-Four Years

You are ALL terrific!

Why a Customer Stays with Harriett’s

A customer had a water appointment scheduled and Diane said a water technician would check to see if the issue was something simple (it was not).  Had to have Mike come out at night for no cooling and he was wonderful.  Explained everything and got the customer cooling again.  Wanted to thank Diane, Josh and especially Mike for getting his air conditioning unit going again.  It’s why he stays with Harriett’s.

Great Company, Great People!

Your plumber is extremely professional and knows his stuff.  Great company, great people.  New Rinnai tankless water heater installed in 2-3 hours.  Great stuff; very happy with the service provided!

Five Stars Review for Rheem Furnace Installation

All the guys from initial contact to installation were great.  Selena in the office was especially helpful in wrapping everything up.

The BEST in Water Conditioning

Brian kept my old water conditioning system working for over ten years. When it needed to be replaced three years ago, I called Harriett’s and requested Brian. He not only installed a new system two days before Christmas, but recently serviced it and found a leak that was making my pump run. Brian is the BEST!

Appreciate Kind Treatment

The service by Mike was excellent.  Customer service by Michele was also excellent.  They both displayed respect, concern, and patience.  As a senior citizen, I appreciate the way I was treated.

A Model Team

Diane was funny, sharp and an excellent communicator.  Dave the technician solved the problem like a surgeon.  Harriett’s has a model team.  I’ll spread the word.

Best Technician Ever!

A customer from Browns Mills called to praise the knowledge of our technician who “has the heater running better than it has in years!”  He said that the technician was not only knowledgeable but also gracious and eager to please. We agree!

New Water Heater

Jim H. installed my new natural gas water heater (converting it from my existing oil burning water heater). He was tremendous!! From the initial evaluation to the install, Jim was nothing but courteous, informative, professional and left the place cleaner than when he found it! Excellent Service!!

Josh is a True Professional!

Josh was terrific…he fixed our water problem and serviced our water softener. We LOVE Harriett’s and now we love Josh!  He’s polite, respectful, direct, able to explain everything he did and recommended, honest, and not even a teeny bit pushy…the best! I thought the price was very fair for having GREAT water again.

50 Years a Harriett’s Customer

In the 90th Anniversary year of our company, we got a lovely note from a customer who is coming up on 50 years with us. Talk about having confidence in a business! We’re so blessed to have folks like Kay F. in Medford who believe in us and spread the word!

Harriett’s is synonymous with excellence!

As an established customer since 2013, we send appreciative THANKS and special praise to you as so evidently proud of your company’s integrity and work ethic with your team extending all of themselves personally as well as professionally with exceptional caring attention.

Every team member was patiently gracious, courteous, applied their technical expertise in problem-solving, educating, and advising us. The installers were professionally knowledgeable while installing a new Bryant Two-Stage Variable-Speed  Condensing Gas Furnace, a new Bryant Preferred Series Air Conditioner, and new Condensate Pump – and they took the extra step of double-checking everything. It is so refreshing to deal with first-class conscientious people who obviously have a genuine interest, passion, and enthusiasm for obliging and satisfying their customers.  Such remarkably nice people are truly remembered!

Saved My New Home from Potential Disaster!

A technician from Harriett’s was out today to clean my dryer vent and discovered that the power cord to the washer was horribly frayed. He told me that he could not in good conscience leave my home with that appliance connected to the outlet. I took him at his word and called my electrician who heartily agreed with your technician’s warning and replaced my washer power cord. Your technician saved my home and possibly more from what could have been a disaster, if I had run the washer as I had intended to do. Thank you Harriett’s for having such conscientious technicians!

No-Pressure Sales and Service

I especially like the no-pressure way of business – yet information and explanations are given in order to make educated decisions.

Techs are on the ball!

Everyone is so nice, when I call. Harriett’s takes good care of my heating and air conditioning equipment and generator. I never have to worry – I know I’m in good hands.

Don’t Wait – Do it Now!

I upgraded to a modern, efficient oil furnace in 2016. It was the best decision I have ever made, and I wish I’d done it sooner. There has been such an impressive drop in my fuel costs. I’m telling everyone I know not to put off upgrading their heating equipment.

Harriett’s to the Rescue!

There were two wild kittens born in our backyard. The AWA told us that we had to litter train them and get them to allow touching for at least two weeks before we could drop them off for adoption. We put them in a small bathroom a week ago and yesterday woke up to only one. The other kitten had pushed the very heavy brass floor grate off and disappeared into the heating ductwork. We called Harriett’s for help, and because we’re regulars, you sent someone in a few hours. He rescued the lost kitten! We’ve always been impressed with your people over the years.

SO pleased with Harriett’s!

I absolutely LOVE Harriett’s! When my air conditioner failed on a horrendously hot day in July, Harriett’s responded within a half hour. I am enjoying being cool once again…and will be having Harriett’s Plumbing Service remodel a bathroom in the next couple of weeks.

New Tank for Cedar Run
“Many THANKS to our friends and the staff at Harriett’s Energy Solutions. They are replacing our older tank with a newer and safer one supplied through a grant through Oil Heat Cares.”

I like feeling confident that my water is safe, and Brian and staff give me that confidence.

Quality of Service Across the Board

All the staff, from the switchboard to the customer service folks to the technicians, Harriett’s knows that it takes to employ and keep a staff who are efficient, courteous, and caring. Today we want to acknowledge in particular the excellent service we received from your service technician and service manager. They put their heads together to resolve a troublesome problem with our water heater and wouldn’t give up, until they’d got things running right again. My wife and I greatly appreciate their professionalism.

100% Trust!

Harriett’s technician, Jim, was just at our home. I wanted to make sure that everyone knows what a gem you have in this guy. He’s super knowledgeable, patient about explaining things in terms a homeowner can understand, and leaves the customer with confidence that the actions he’s performed were exactly what the job needed!

Harriett’s is a company I can trust!

Tidy Tech

Your technician was very courteous, and he left everything neat and clean, which is greatly appreciated!  He also explained what went wrong and repaired the problem.  Harriett’s is awesome!

Harriett’s has been taking care of our water since we moved here in 2003.  Your tech is respectful, courteous, very knowledgeable and professional.  He is even respectful of customers’ property – he removed his shoes before entering my kitchen!  I wouldn’t have anyone else looking after our water!

Those HES Techs!

Your technicians give good suggestions.  They’re very friendly and knowledgeable.

Stellar Service!

Harriett’s goes above and beyond in service to their customers.

Plumbing Kudos!

My customers and I are impressed with your plumber’s knowledge and professionalism!

Look for Harriett’s on Angie’s List

I think the service was the best I’ve had, and you have excellent technicians.  I’m going to put Harriett’s on Angie’s List for excellent service.  Just continue, and word will spread.

Keeping an eye out for our customers!

Harriett’s Takes Care of Us!

Over the past few years, Harriett’s has installed a new heater and air conditioner for us. They have serviced our equipment whenever it needed attention and have always looked after our best interests. Thanks, Harriett’s, for caring!

Harriett’s Field Techs the Best!

I retired from the NYPD after 30 years,  where I experienced a LOT of bad people.  I’ve never experienced such a fine group of human beings as Harriett’s has.  They’re decent people and knowledgeable about the equipment they service.

Give Other Businesses Lessons?

Keep up the excellent work!  The follow-through in all aspects was terrific.  You should give lessons to other businesses!

Conversion to Gas Heat

From your sales department to your office associates to your installation technicians, it was a great experience.  We love our gas heat!

Energy-Saving Installation

Thank you again for all of the work that Harriett’s did on my heating/air conditioning/energy-saving work.  Even in all of this heat, the air conditioner hardly runs.  The attic fan turns on early in the day and does most of the work.  I can keep the thermostat at 73-75°, and it’s very comfortable.  All this in addition to my monthly fuel budget figure going down $40!

Emergency Response

You are the best!  You came on a Sunday 30 minutes after I called.  Thank you so much!

Personal Client Care

Just wanted to take a moment and recognize the outstanding service I just received from Harriett’s Oil in Medford. After being without air conditioning for several days and working thru several contractors, I contacted Harriett’s to look at my problem and had them provide a repair proposal. During the course of the repair some unforeseen conditions arose that forced a delay and additional cost to the repair. Bob Harriett got involved personally and provided a portable cooling unit to get us thru this current heat wave, expedited the repair, and honored the original proposal. In today’s world of email and call backs, it is a pleasure to do business with a company that truly cares about their clients.
