HVAC Contractor in Fallbrook, CA

Seth and his team were super responsive, quick and helpful. I was impressed that they came, did the diagnostic and fixed the issue in one go. They communicated clearly and professionally. They were on time and responsive. Totally recommend this company.

Excellent service by Seth and his team. They were here for two days, always on time, with an excellent result. I can definitely recommend them to anyone needing HVAC service — in fact, I've already booked them for a different job.

Coastal does a thorough evaluation and provides sensible recommendations for maintaining our heating and air conditioning. I like that Coastal stays focused on heating and A/C and is not adding plumbing to their service offerings. I had been disappointed by previous providers that expanded to plumbing and changed focus to potential sales opportunities rather than service. I appreciate Coastal’s focus on my heating and A/C system and their straight talk to do the best maintenance to keep everything functioning well.

I have had Tanner come out with his dad, Seth, for a very, very long time. Tanner is a very sweet, and proficient young man. He did a very good, thorough job, and I’m very happy with the work done today. I will go nowhere else for servicing my ac or furnace!

Got a new system installed by them! Hands down best service. On time, fair price and quality work. Thank you Seth and Tanner for the amazing work.
