Always great, professional service. Friendly, thorough, conscientious and done right the first time!

Highly recommend these folks; friendly; professional; prompt and honest. I was given a quote for what my service COULD cost if they needed to use both parts that were ordered, but they only needed one and not a single problem since. I wouldn't use anyone else. Thanks ever so much to this great company. Nancy Ray read more

Best for sales, service, and installation. Just finished installing new furnace and added AC. Fair pricing, Great Service and Install. Team works hard to not be in the way while doing their job. They know what they are talking about and can be trusted to do the job right. read more

First 2 services were awesome. But $4100 water heater quote with no itemized cost listing states they are not interested in residential home repair. read more

I couldn't say enough of great things about this company. I used another one previously in Rochester which was awful. East Coast is receptive, professional, knowledgeable and everything good! If you choose this company for all your furnace + jobs, you will not be sorry. EMW Dover NH read more

After a difficult time with Heritage Home Service I called these guys. From the first person that answered the phone to making the payment all were professional and polite. Salesmen and install team knew just what they were doing. I saved thousands over the Heritage estimate and they were a drag to try to deal with. East Coast saved the day! read more

I had my old boiler cleaned, repaired, and updated. Corey is a great technician -- thorough, informative, and very friendly. He asked if I wanted him to replace some leaking spigots, and was happy to do the extra work. I highly recommend East Coast Heating and Air Conditioning. read more

We just had two Air/heat Mitsubishi heat systems installed in our wonderful but quite old home! East Coat heat - Scott and Heath and electrician Matt and his team did an outstanding job. All of the technicians were Professional , worked Hard and had a great attitude. Everything went really well. Thank you East Coast! read more

I put down $6,100 deposit and signed a contract in August fir an air conditioning system upgrade. They delayed and delayed...then they said the parts were not available but didn't know when they would come. In then they said the permits we hung up with the city! come to find out the parts were avalible and company representatives could not communicate from one department to another. This is the short version! Anyway I cancelled the job and asked for a refund. It took them a week to do that and today ( 10/29 ) after I had to call them to follow up. The people all seemed very nice but at least in my case not only did they drop the ball they threw it under the bus. read more

I am impressed with East Coast. the tech that serviced my system was friendly and knowledgeable. Excellent customer service. you get the benefits of a larger company but the service of a smaller one. prices are fair and they provide accurate estimates on all service. I switched to them after using a different company in the tri-city area (check my other reviews so you don't make the same mistake). if you are looking for heating and air conditioning service I highly recommend East Coast. read more

It's a cold Sunday afternoon and your pipes won't heat up. Who ya gonna call? East Coast came out on a Sunday afternoon! David Hayes was an experienced, professional and pleasant person to deal with. He fixed the problem.He made me feel that I could trust and be confident in the work he performed. I am very happy to be a client of East Coast. They are a family and locally owned business. I do not give good reviews out lightly, but these guys are reasonable and dependable. Thank you for warming up my cold home!! read more

We had a problem last week when our AC stopped working on a very hot day. I called East Coast late on a Friday and they were able to get a technician out after hours. Doug was personable and very technically proficient and was able to get our unit up and running again. A huge shout-out to East Coast! They were fabulous! Give this kid a raise! read more

we have just finished the install of our On Demand Propane Water Heater. The entire team did an excellent job of keeping us informed and working with our schedule. The employees were respectful of our home and told us what they were doing and why on each step of the install. This is our second product installed by East Coast Plumbing and Heating. We offer our strongest recommendation for their service and sales. read more

Bill at east coast is always super friendly and extremely knowledgeable even about my old school steam boiler. They are always willing to quote work and can be there to do it when you need. I use them for servicing my boiler and also my mini split in the future. Thank you bill! Go bruins! read more

I was referred to East Coast by a friend who hired them to replace a furnace and air conditioner for her. I got an estimate from Josh in September and I will hire them to do my air conditioning in April or May. Their prices were very competitive and Josh was knowledgeable and very helpful making suggestions that would benefit my space. I decided to have my furnace serviced by them to get to know them a little better and Michael came out and did a great job while answering my questions while he worked. When they offered a contest for a free whole house air cleaner I reluctantly decided to sign up and WON. When the air cleaner that I won could not be used in my particular circumstances Aaron went out of his way to find one that would work for me. When it was delivered I was happy to see Michael who serviced my furnace show up. I will be back to review in May after my air conditioner is installed. At this point they have "welcomed me to the family" and have given me respectful and quality service making me feel like I can trust them. read more

I recently had my furnace replaced by East Coast and while the furnace does work great(which is why I gave 3 stars) the rest of the experience left little to be desired. I called East Coast for a quote to replace our furnace after the prior company I had received an estimate from never followed through with coming out to do the job. Justin came out on a Tuesday and said he'd have the quote to me end of that week, very beginning of next week. I waited until the following Wednesday before I called and left a message for Justin to follow up at which time I received the quote a day or two later. After weighing the different options I called a week later to schedule the replacement and was advised I needed to put a deposit down, at which time I did, 30% of the quote. While on the phone I was advised Justin would give me a call to schedule the date of replacement. 6 business days went by before I decided to call and ask if we could get the replacement scheduled. I was transferred to Justin's voicemail and 2 days later, the receptionist, not Justin, called and gave me a date it would be replaced. Furnace went in fine, it was done in a day, the 2 workers were nice, pretty straight forward job. I received the invoice in my email and received a call from billing a day and a half later asking me to pay the remainder of my bill. In their defense the bill does say "due upon receipt" however, with that said, if I have to consistently follow up with your company for your worker to do his job I don't think it's in the best interest of anyone to then call the client and ask for the remaining balance within 48 hours of sending out the invoice. read more

I really like this company. I couldn't have been happier with the furnace maintenance service I received from Corey. He did a great job and happily went over things with me. I will definitely request him in the future. The women at the office are also very pleasant and helpful with all of your questions. Highly recommend. read more

I have gone to East Coast H&AC since I moved to Portsmouth a few years ago. They have done everything from replace my oil tank to simply bleeding and restarting my burner. I have dealt with three different techs over the years and each one has been friendly and diligent as well as totally easygoing dealing with me hovering and being the person who asks a million questions while they work. :) They actually came recommended by my oil company. I never feel like I am being taken for a ride and the prices check out great compared to others local companies. I would totally recommend these folks. read more

Great pricing and incredible service! Pete and Justin were able to meet me the morning after my initial phone call. Their quote was extremely reasonable compared to other local HVAC companies that I have done business with in the past. They were even able to schedule the work for a weekend so that my tenant's operations were not interrupted. I was extremely satisfied and impressed with East Coast's service. I would recommend to residential and commercial customers! read more

I've used them a couple times for cleaning my oil burner. They are great. Justin was as in communication via email with me even on the weekend when I had to change the day I needed last minute. They were accommodating to me as I have an infant and asked if they could wait until 8:30 am to come which they did. read more

I needed to have an annual service performed. Appointment was easy to make and Eric showed on time. Fair and reasonable price paid. Would strongly recommend. read more

WASTE OF OUR TIME ..... We waited two weeks for our appointment to have Justin come out and provide us with an estimate for the Mitsubishi ductless A/C for our entire house, including a finished walkout basement. It has been 7 weeks and three follow up calls to both Justin and the owner, and we never received the estimate. We paid to have our carpenter on site for two hours during Justin's visit to discuss options of ceiling units vs wall or floor units, how best to run/conceal the condensation lines, and placement of the condensers outside so as not to intrude on our outdoor pool/spa/fireplace area. The job is not an easy one, hence the reason we had a carpenter on hand. Our goal was to install a system in as unobtrusive of a way as possible so that the A/C did not look like it was an afterthought to the house, but rather was part of the original build. Justin wasted our time and money(paying the carpenter) in pretending that East Coast HVAC had the ability and experience to consider a job that entailed anything more than straightforward ductless wall units. When he saw the scope of the project, he had the opportunity to advise us that this was outside their wheelhouse and decline the opportunity. Instead, he wasted our time. Then, neither he nor the owner had the courtesy to return our calls. This was a big job - quoted by two others as between $55,000- $80,000, and this is how we were treated. Don't waste your time with this company. There are plenty of others our there who want the work and who will return calls. read more

I don't recall how I found out about East Coast HVAC, but it turned out to be a great discovery. Peter came to my home in the summer of 2014 and gave me a price for Mitsubishi heat pumps which beat all other proposals. Not only that, installation was completed before the estimated date. Last winter the heating cost for my house was 50% below the previous winter when oil was my fuel. Also I now had whole house AC which I didn't have previously. Finally the staff filled out the paperwork for my rebate.Thanks to all of the East Coast staff; you did a first class job. Alan in York, Maine read more

Called to arrange for a quote on a water heater replacement in Seabrook NH... was told they are not taking on any new customers.

East Coast is the BEST OF THE BEST!! Just can't say enuff good things about them! I would give them 10 stars if I could! We had some issues with our furnace lately, & they sent their techs over right away! Extremely knowledgeable, friendly, and professional! Would never change companies ever! Thank you to Chuck at Home Town Oil for recommending them!! read more

I was thoroughly unimpressed with the service I received from Eastcoast despite the good yelp reviews. After I spent thousands of dollars for a new boiler, they took weeks to come back to pick up my old boiler, they never came back to skim the system after installing my new boiler, and they failed to clean up after the job. To top it off they left the pressure too high and as a result my pipes were clanking and and the system wasn't operating efficiently. I am not a happy customer. read more

East Coast was the most reasonably priced of 3 HVAC contractors solicited for installation of an AC unit into a new home. Justin was professional, honest and courteous when scheduling a convenient time to inspect the home and provide an estimate. The installer as also friendly and knowledgeable. He made sure to test that the unit was working properly after installation and checked the temperatures in our house. Billing was easy with online invoices, and they helpfully reminded me to register my product for an extended manufacturer's warranty. If you need an HVAC contractor in the Seacoast Region of NH, East Coast is the way to go. read more
