They installed our new HVAC system in 2013. It has worked like a dream ever since. They were fast, professional, and efficient. I recently needed the air conditioner condensate line flushed and cleaned out. Kim in the office is fabulous. She got me on the schedule right away. Scott came out exactly on time and was professional, friendly, and efficient as he fixed the problem. He answered all of my questions and helped me understand how it all worked and what I can do to help my system work best. I plan to explore the Aprilaire filtration system to help my husband's allergies. I highly recommend

Fair prices, decent on availability, professional and trustworthy. Had them out twice on two different rental properties, both times the prices were reasonable and the issues resolved first time and quickly. Highly recommend.

Have to say I never write reviews... I just assume that people are going to do the right thing and ... be honest. I got their name from my son who is in the construction buisness, folks, these people are honest and fair - and more than that - they went out of their way to show me (not TELL ME) what was wrong with my AC and how it could be fixed!
The fan on the AC unit was not working and the switch needed to be replaced - done at a very reasonable price plus I had the tune- up on the AC done as well.
Both the AC and the heater are both, over - 30 years old! They don't even make the coolant

We had thee most awesome, knowledgeable and helpful tech named Scott come out today. Diagnosed immediately that our run capacitor had died. Was even honest enough to tell us that we had a warranty on it, so we didn't have to pay full price. He took his time to answer all of our questions and taught us SO much about the entire unit, maintenance etc.
This company is top notch with the highest level of work ethics and integrity. A lot of other companies could learn an awful lot from them!
Jennifer got us an appointment in only 1.2 days! Run...don't walk to Seaside AC!

My consultation was costly and the diagnosis of my unit was unclear; I was given two quotes for separate repair work. I felt I was being ripped off.

They are okay. We ordered a tuneup for $95. The technician inspected everything and told us that the old AC can't gain more efficiency because, it's old. Maybe it's true. Towards the end of the tuneup, the technician broke a pull-out disconnect switch. He said it's already broken which again, may be true. The AC is dysfunctional at that point so he replaced the switch. The switch's retail price is $15. The technician showed me that the repair price is $250 as per company policy. We paid $195 for the total tuneup and the replacement of pull-out disconnect switch.

These guys are very professional. I called for a tune up on my 31 year old air conditioner, which had rotted away at the bottom causing all the refrigerant to escape. Needless to say, I needed a new 3 ton AC. Alex got me into a new ACPro and I finally have a cool house for those hot Orange County summer days. They showed up exactly on time and my two installers worked straight through for 6 hours doing the install without taking a break. Alex had another job, but came by several times to check on my job and did a thorough post inspection. Although he told me he is only 22, this "kid"

We called Seaside to have a new Heating/Air Conditioning Thermostat installed.

We feel fortunate to be assisted by extremely professional service technician - Jose Castro.

What seemed like a pretty straightforward installation became a little complex. Jose took the time to help us understand the settings & procedures on our new thermostat. What seemed simple - wasn't.

I would not hesitate to recommend Seaside to anyone looking for a high degree of competence & professionalism. One of the things people are looking for when choosing a company/service/technical support is a company

Had a new unit installed. Damaged my house during installation. Hired a 3rd party to fix the damage. 3rd Party took over a month to schedule an estimate. Refused to give me an appointment. Said "We'll call you when we're on our way" - so they can come anytime over the next two weeks, and I was just supposed to be sitting around waiting for them to show up. They never did call to come back. Salesman did not return phone calls. Administrative staff sent insulting messages and had no communication with sales team. Very unprofessional. There are a lot of good HVAC installers in OC - use one of them

The best professional HVAC company we have ever used. Highly skilled trained staff from their sales advisors to the service technicians who are able to answer your questions, respond in a timely manner and will take the time and patience to be sure you understand everything you want to know.
Reasonably priced services and heads above the rest when it comes to offering all different types of options and brands of furnaces and air conditioners that we felt we were given more choices to secure a system tailored to our specific needs and not sold equipment we did not necessarily need. We were given

With the temperature inside my house nearing 90 degrees, I desperately needed a technician within the same day. After calling several other HVAC companies and none of them being able to send a technician to my house in less than 48 hours, I called Seaside AC and Heating. Jose was at my house in just over an hour, took five minutes to diagnose the issue, and completed the repair in 15 minutes. The AC was back online and running strong thanks to Jose. A very satisfactory experience!

For service, courtesy and professionalism these guys can't be beat. They do the work you hired them for without trying to pad the bill by finding other problems which must be completed to do the job. If they discover any problems they will discuss them with you. If you have any questions they will answer them. Other businesses could take a lesson from this company on customer service.

Our air went out a couple weeks ago in the worst time (summer 100+ degrees) and had the pleasure of having Darren come out to inspect the problem. Sure enough we knew the system had to be replaced, as it was a 30 year old system. Seaside gave us a great deal and did the work in a timely manner. Seaside did a great job installing the new unit and ducts. We spoke about my Marine days, it's always nice to see the support for our military and our veterans from companies. Thank you seaside

As a second generation HVAC contractor, Victor Serrao & Company provide intelligent, knowledgeable service. Their customer service is reliably exceptional.
