We just had a split air & heating system installed. Their bid for install was over 50% less on labor verses competition. They did an excellent job on install. Russ Desert shadows RV Resort. Cathedral City.

They have serviced our AC and heat for several years and have always been reliable and trustworthy. They just installed all new AC and furnace for us and did a great job for a reasonable price. Complete professionals. We got 3 other estimates and Seaside was the most responsive, fair and easy to deal with by far!!

Everyone at Seaside does a good job. They all care and I especially like that they work well as a team. We first used Seaside via our Home Warranty contract. It was a blessing. Mike was our first contact. He knows HVAC. He gave us good advice. He and his crew installed a new AC and Furnace, thermostat, air purifier. He advise us to get an Ecobee thermostat and we've been very pleased with it! Everything they installed was of first rate quality. 1 /12 years later when we needed to re-insulate and replace all our ducting, Bill was our contact. He was stellar in service, knowledge, timeliness of the work done, quality. Most importantly we know that the work that got done by Bill and his great crew is rock solid. On top of that, Bill was VERY understanding of my husbands challenges in having a crew of people come into our house. He was very compassionate with my husband's special needs. Seaside is a blessing to us. We will only use them for any HVAC related services. These words pale in comparison to the comfort and satisfaction you will feel once they've improved your HVAC system.

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 and avoid Seaside.

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 their name and number from a neighbor who raved about the company and we can attest to the fact they delivered more than we expected and we felt we also wanted to pass the information along knowing how tough it is to find honest, ethical, highly educated service providers that sincerely want to make their customers happy👍
