    • Edgar and Sean came to check on the system we put in about 7 months ago. They always go out of their way to make sure we’re happy and that everything is still working and up to speed. Very professional and helpful. My new unit came with a service that has Haven come out every 6 months or so to check the unit. Great company

    • Very professional and responsive. My heater was not working properly and Haven was able to send out Cody the same day within 2 hours. Cody is very professional, polite and very knowledgable. Fixed the issue very quickly and the charge was minimal. Would highly recommend Haven.

    • Haven installed our HVAC system a few years ago and has done regular maintenance visits since then. Their team is friendly, professional, and very reasonably priced. Best of all, they do all of their scheduling via text. Five stars alone for no unnecessary phone calls. ?

    • Our furnace was down, so no A/C and no heat. Even before our furnace was down, our A/C stopped working. We called Mighty Ducts/Haven and they were able to send Cody to our home. Cody was very professional and friendly. He explained to us what happened and provided us with a repair estimate. He was able to repair our furnace, including getting our A/C up and running the same day. He also resolved other issues we’ve had with the vents. He is efficient and is a very hard worker. We would recommend this company to our friends and family. We really appreciate your professionalism and hard work, thank you Cody!

    • 100% Grade A service and reliability from the the customer service, repair consult, sales and installation crew. Our old unit was 23 years old and costing a fortune to run (even with solar energy). I did my due diligence and searched for a solid company with great reviews and reputation and Haven Air is the best. We live in Ontario and they are based in Anaheim. It was a big job for our 3200 sf home, taking 2 full days. They were never late, cleaned up thoroughly every time, very courteous employees, knowledgeable and professional every step. Andreas Laux was my lead sales guy and man on the job. No pressure to purchase anything and was thorough in his explanation of the different units available for our size home. He followed up with me every day and kept me informed. I was very comfortable with him and highly recommend this company for either repair or a new A/C or furnace. I dont do social media but i wanted anyone looking for help with their system to know you can trust these guys to do good honest work for you and for the years to follow maintaining the unit for you. So glad I found them ☺️ Lisa D

    FREQUENTLY ASKED QUESTIONS

    What we can do for you!

    Haven Air Conditioning has a proven track record with thousands of successfully completed projects. Haven Air Conditioning has maintained a 5-Star reputation for over 20 years.

    Call us at (714) 332 – 6302 for more information or to schedule an appointment to discuss your HVAC design project.

    Custom HVAC projects require a larger investment for the following reasons:

    • Custom HVAC projects usually have more equipment integrations like zoning systems, humidifiers, advanced IAQ products, linear diffusers, etc.
    • Crew labor days – Custom HVAC installations require a dedicated project manager and have significantly more ‘crew labor days’ allocated to them in order to complete the projects.

    Call us at (714) 332 – 6302 for more information.

    Clearly, quality equipment is an important factor, and that’s why Haven Air Conditioning only uses top brands. 

    However, the quality of the installation, driven by the expertise of the contractor and his team, is equally, if not more important!  

    Top-quality equipment and a top-quality contractor ensure a successful outcome.

    Yes, all mechanical installations require building permits and Title 24 compliance in California. No exceptions. Stiff penalties apply to the homeowner and contractor.
