I needed help with my heating unit. It was 7 degrees outside and we could not wait for someone to come and take a look of the heating system we have. I called a company recommended by my sister and they never showed up. I was frustrated and felt Like my last option was to go go to a hotel. I ended up calling Coastal and they came in within 2 hours.

It was 2 am. They were patient and very determined in finding the problem. He fixed it and also took take care of a pipe leaking I had in the basement. I am very pleased with the service provided

******BEWARE OF COASTAL HEATING AND COOLING ****** In my opinion the business ethics of this company are nonexistent. I called to have my furnace serviced. While the service provider did show up rather quickly to perform the service call, he was completely disrespectful. Not only was he disrespectful but I also discovered the parts he used were incredibly marked up and his labor rates were highly unreasonable. Please, do not go through the havoc of contracting with this company.

He may seem like a decent human being but he'll take advantage of you any way he can. After he supposedly fixed my furnace, I discovered it was still leaking. I asked him to come back and perform a secondary check on my furnace which was still leaking. Instead of determining what the issues, he blamed the initial installer of the furnace. Further exacerbating the situation, he decided to insinuate that I never paid him for the original service and he was requesting payment now.

He later said to me in a threatening manner that he would follow me to the bank to obtain his fee. I subsequently advised him to leave the home and I would not use him again due to his unprofessionalism and lack of knowledge regarding the situation. Stay away from this guy. There are plenty of more reputable firms out there to service your HVAC needs.

When my heating system ceased to work on a Friday night at 9:30 I thought who will answer the phone at that time of night after working all day. I called Coastal and told the man that answered that there are two disabled people that live in the house and that we just lost our heat. He said " I'm going to eat my dinner" and I'll come right over. That meant he just got home from helping another customer.

He was wearing his mask when he arrived. He had the problem analyzed in a few minutes, he fixed the furnace than he trudged through 2 ft. of snow to the oil tank in the back of the house. This employee is dedicated, knowledgeable and was still willing to engage in a conversation at 1am. We are blessed to have a company in the seacoast that hires good people. Thank-You for answering my call. Doreen La Flamme, North Hampton

Jon was excellent! From diagnosing the issue to sourcing the best unit at the best price. Arrived on time, quick clean and professional. Even went the extra mile and did some cleaning of the area my AC was in! Would absolutely recommend Costal Heating and Cooling!

very communicative and reasonable price compared to other 2 quotes we got. Needed to replace a 10 year a/c system. Happy with the work and service.

Buyer of services from this company beware. Recommended by the oil company I was using at the time, I had Coastal come look at the problems I was having with a boiler. After a couple months and a few thousand dollars, the bad news was broken to me that the six year old boiler needed to be replaced. I decided to get a couple more opinions and I'm glad I did.

Come to find out, parts were being replaced that had nothing to do with the true issue and for $240 the issue was corrected. It's now three years later and the boiler is running strong and I'm still $8,000 richer. Trust me, get a second and third opinion.

Very Pleased with the service. I had to replace my air conditioning unit after many years and I called may companies trying to get a price. Most of them wanted to charge me between $ 140 to $ 250 for them to come in and tell me that I needed to replace the unit. " I already knew this ". Finally I called Coastal and after expressing my frustration Jon said to me that he would come in and check the unit at no charge.

Later that day he gave me a price for the new unit and it was a competitive price. Its been 3 months and I had no issues. They are transparent, professional and on time. Thank you

Replaced the furnance. After getting couple of estimates from multiple companies I decided to hire them to install a new furnace. Gotta say that every company gave us different prices but this one was right on the money. Took them couple of days to come in and do the job and overall it was a good job. We are happy with the results and will continue giving them the service once a year.

Good and efficient. I needed to replace an a/c unit and after various estimates I decided to go with Costal. I am happy with the outcome. It is hard tot trust people because most of the time they don't really care about the customer. Jon actually took the time to go over the estimate information. My unit was replaced in 2 days and is working just perfect. I will recommend this company to everyone. Thanks

I live in Portsmouth, NH and Coastal Plumbing Heating and Cooling Specialists helped me out when no one else would. I was worried that I would be over-charged and the work would not be done correctly. I was wrong. they were GREAT!

Had few leaks from the water heater and needed to replace few pipes , also the water pump was no good and needed a new one ! I called 2 companies to get prices one of them was ridiculous expensive . This company gave me a good price and I verified it . It was fast, no mess and decent price.
