Incompetent company. They’ve been to my house four times and now a 5th for the same AC issue and still haven’t fixed it. They always show up late, misdiagnosed the problem, and insisted on replacing the entire unit when the truth was simply a kink in the line. On top of that, they constantly track dirt into the house, forcing me to clean and mop after every visit. They don’t wear shoe covers or gloves, which is basic standard practice with any professional company. To make matters worse, they even ruined a brand new hand towel in the guest bathroom, which is rarely, if ever, used by bleaching it while cleaning their tools. Save yourself the frustration and look elsewhere

I had Ryan quote all new AC systems as two had failed and only one still worked and asked about replacing the forced air heaters. He quickly provided a very competitive quote and I decided to get all 3 systems replaced with new AC / Heat pump / and forced air heaters for a little less than most competitors wanted for basic systems. I took a week to install 3 systems and they guys were thoughtful and courteous and cleaned up well. The units are quite, efficient, and kept us cool all summer looking forward to using the heaters in the winter.

Call them last minute in a pinch as there was a mix-up with our Contractor Building our Adu. They came out same day the next day they had line sets installed so we could pass inspection on the preliminary. Today they finish the installation and I can't say enough about these guys. You can tell that these technicians know what they're doing and enjoy it, and the pricing has always seemed Fair to be honest I have never shopped as the quotes they have given me seemed well under what industry standards are supposed to be. I will never use another HVAC company again. We used them years ago on an upgrade to the main house and we were happy then. They've also been out multiple times for routine service and maintenance and whether we're paying a lot for a new system or a little bit for a tune-up they have the same attitude great customer service and again in a pinch they really pulled us out of the sling.

I'm disappointed in Seaside. No follow up regarding replacement estimate. I called and they said they would check and call me back. Still no follow up or call. It's been 5 days. Also, The Tech left a part on the ground (found by 2nd company I called) and his analysis was wrong regarding what needs replacing. I guess Seaside doesn't need the work or care one way or another.

Had a great experience with Seaside. Steven, Kevin and team were professional and communicative throughout the whole process of installing mini-split units. They were thorough with install and left the home in clean condition after the work was done. I highly recommend using Seaside Heating & Air Conditioning.
