East Coast Plumbing, Heating & Air

I started my search for a plumber to install a pot filler rough-in on Yelp. Contacted 4 plumbers…read more Bryce from East Coast was the first to reply almost instantly. After a brief text conversation I was quoted a price and directed to call to set up the job. A few day later I called and spoke to Kelly, who quickly set me up an installation date a week later. (By this point, only one of the other 4 had contacted me and they were scheduling a month out!) On the day scheduled for the installation, Tony, showed up, on time. He was kind, polite and helpful, explaining exactly what he was going to do. He quickly and efficiently completed the job, even vacuuming, when done. He took time to review the job and explain my next steps, as I was installing the faucet myself, at a later date(as part of a kitchen remodel). Based on this experience, I would highly recommend East Coast Plumbing Service for any plumbing job. They were fairly priced, efficient, kind and got the job done quickly.

I cannot recommend this company based on my experience. I…read morecalled because of an active water leak affecting my bathroom and closet ceiling. Before the plumber arrived, I had already done some troubleshooting and explained that the leak became worse when water was being used in the house and slowed significantly when I shut off the main water supply. The plumber briefly looked around, noticed a small amount of water in the HVAC condensate pan, and immediately concluded that the air conditioning was the cause. He would not seriously consider the information I provided or investigate other possible plumbing-related causes, despite the clear pattern I described. I felt like my observations were dismissed without a thorough evaluation. On top of that, there was a non refundable fee of $179 for the visit. When you're dealing with a leak that is actively damaging your home, you want someone who will methodically diagnose the problem rather than jump to a conclusion. Unfortunately, that was not my experience. I hope the company takes customer concerns more seriously and performs a more comprehensive assessment before ruling out other possibilities.

Just had a Carrier Infinity system installed. The crew was fantastic…read more They were neat and very knowledgeable. We had a minor issue with a damper that they are taking care of. Was nothing the did, it was something done during new construction 14 years ago. The infinity system has been wonderful so far. Can't wait for heating season. I highly recommend Coastal Comfort. Process from sales rep to the installation team was seamless. Thank you for a great experience!

I have been a loyal 19 year customer with annual maintenance every one of those years. I LOVE…read moreCarrier equipment as I designed my own system layout as far as damper and trunkine placement. Previous management completed the job with spectacular results. I have a top-line Infinity gas back-up furnace, 5 dampers for a single unit system with 4 zones on two floors for a 3300 sq. ft. home. (I cleared drywall space in the basement ceiling to facilitate two trunk lines parallelling the I-Beam in the basement; some ducks up, some down). I have reviewed Coastal Comfort extremely well up to the replacement of my outdoor heat pump three years ago. After all these years of my many positive experiences with Coastal, especially regarding the 'non-management' front office staff and the highly qualified technicians that I've grown to love, I can tell you that this company has changed to the negative.... after the transition from the now-owner's father- Kevin Coleman. There's such an emphasis on growth ambitions, market share, profitability.... General and Service Managers have been hired that are nothing more than confrontational and abrasive in their communication styles if anything doesn't go as expected for them.. A total inability to listen----and it's supported by the now second-generation owner!! LOL Bottom line ---Bryant equipment is EXACTLY the same as Carrier. I was told this by the distributor they purchase all their equipment from! The equivelant of Carrier's Infinity furnace that I own and love is Bryant's 'Evolution'. It's just another brand running down the same assembly lines in the Carrier Global manufacturing plant! Do your own research for a local dealer of your choice, whether it's Carrier or Bryant!~ Sometimes a smaller company is much preferrred verses one that doesn't exerecise basic customer communication skills on a managerial level or truly listen to a customer when ther is an issue. Here's a takeaway----Call Coastal Comfort , or when they call you, they always recite the disclaimer statement of "You're on a recorded line" Who cares!! It's a partial intimidation tactic that they actually spend a lot of valuable minutes on to review hundreds of calls instead of a fucus on customer satisfaction issues. It's almost humurous thinking about all the wasted minutes when more productive time utilization can allow the business to prosper more effectively.
