Coastal Heating Cooling Specialists

When a 2025 customer came home from vacation to a house with no heat, Jon was there within an hour on a Sunday, and that customer said he and his team had everything running again shortly, for a fair price. Coastal Heating Cooling Specialists names Hampton Falls, Exeter and Seabrook as its service area and says it has been in business 25 years. Its website lists boilers and furnaces, water heaters, ductless heat pumps, spray foam insulation and plumbing among its services. Jon W Arndt's New Hampshire HVAC licence, number GFE0801342, is active on the state registry, and his Maine HVAC licence, number MS30005564, is active on Maine's state registry. On Google the business holds 4.3 stars from 54 ratings. A recent customer said a boiler more than 25 years old was leaking; Jon and Rick looked at it, gave a quote quickly, and in less than a week the household had a new high-efficiency system, with work running well past normal hours. A recent reviewer said he showed up when he said he would and called back the next day to make sure everything was working. A 2025 reviewer wrote that Coastal was listed as a 24/7 emergency contact on their oil company's website, and that after walking them through troubleshooting by phone on a Saturday afternoon, John was at the house within an hour of the call. During a heat wave and after normal business hours, a 2025 customer said, Jon answered the phone, arrived within the hour and diagnosed and resolved the issue on the spot. A 2025 customer described a Mitsubishi 12K single-zone heat pump installed within a week, with Rick opening a wall to reach the existing line and then repairing and drywalling the access point. A 2024 customer said John and his team completed a major gas pipeline and distribution system in 2 days. In a 2023 review, a customer said they gutted the plumbing during a cold snap and brought the utility room up to date with a boiler and on-demand water heater, and even painted the natural gas pipe. A recent one-star reviewer said they had a major issue and the company refused to acknowledge its error. A 2024 customer objected to a $388 charge for charging a split unit, saying he was not there 20 minutes and never cleaned or looked at anything else. In a 2021 review, a customer who had a furnace serviced said the parts were marked up, the furnace was still leaking afterward, and the service provider blamed the original installer and said he would follow the customer to the bank to collect his fee. Its BBB grade is C+, and the BBB lists one complaint.
