After my 30ish-year-old oil-burning boiler finally gave out, they provided incredible next-day service for a complex system that handles both baseboard heating and domestic water. The experience was seamless from start to finish. The salesman was a true professional—he showed up to assess the next day, and didn’t try to upsell me on things I didn't need. Instead, he prioritized getting us back up and running, ordering the new unit that afternoon and having it delivered overnight. The technicians arrived first thing the next morning to dismantle the old beast and install the new system. I’ve used Coastal Air several times at a different property on a more straight-forward system, and their honesty and quality of work have been consistent regardless of the size or complexity of the project. They are officially my first call for any HVAC needs. Thank you to the entire team for the peace of mind! - 5/5 — Anonymous I highly recommend coastal air for your heating and cooling system. Noah was my technician and he did amazing job he found out where the musty and mildew smell came from it was a old dirty filter on the bottom of the hvac system that I never knew about he explained everything well to me and what he was going to do. my house smells a whole lot better thank you again Noah. - 5/5 — Anonymous I have been a customer of Coastal for 10+ years. I cannot say enough good things about them. Great work and they do not try to up-sale you. Noah was the technician that performed the annual maintenance on my oil hybrid heating system yesterday. He knew the system because he was part of the group that installed it and rebuilt my duct work system. People like Noah and others at Coastal Air is why I would strongly recommend them. Qualified technicians, timely service and good prices. - 5/5 — Anonymous I am so grateful I found this company. I renovated my garage into a play area and coastal air provided me a quality mini split at a reasonable price. So when my furnace stopped working at the beginning of winter I knew exactly who to call. No one wants to spend thousands of dollars before the holiday season but, we also don’t want to freeze. The consultant was knowledgeable and very kind and compassionate. He did not try to force me to buy a system I could not afford. He gave me options and I could choose what worked for my budget and home size. Within a few days I had a new heat pump system installed. Shawn and chino were amazing, they explained what they were doing and always informed me of how the job was progressing. Afterwards they helped me program my system and made sure everything was working correctly. Chris was also so knowledgeable and helpful in explaining how the system works and the warranty information, he made the payment process very simple. I hope I do not have any more system issues but, if I do I know what company I will call if I am in need of quality top notch service. Thank you 🙏🏽 to the whole team. - 5/5 — Anonymous We would like to express our gratitude toward Noah, the technician who performed our HVAC maintenance for a second time. What a pleasure it was to communicate with him. He is extremely knowledgeable, caring, friendly professional and we are lucky to have him for the service we needed. We had a terrible experience with our previous service company, but what a difference with Coastal Air. Thank you Noah so much, we hope to see you again in April, 2026. ## FAQ **Q: What HVAC services does Coastal Air provide in Harrington DE?** A: Coastal Air offers full-service heating, cooling, air quality, and gas piping solutions for both residential and commercial properties in Harrington, DE.
