Recognized For Delivering Superior HVAC Services

Exceeding Client Expectations in San Diego Since 1984

The difference between a “pretty good” technician and a true master of the trade may not be obvious at first, but it will be obvious over time. As the years pass by, the difference between sub-par installations and repairs and high-quality ones will show itself in your home’s average temperature, your monthly energy bills, and your increasingly-frequent repair bills. And years after you get your HVAC system installed, who will you turn to? More often than not, it’s the expert who will still be answering your calls and repairing your unit. That’s what sets the service at Oak Island Heating & Air Conditioning apart from other HVAC companies in Escondido. We will continue to be here for your home and your heating and AC system, following up our service calls with durable repairs, thorough maintenance, and installations that allow for the highest possible performance.

See What Our Customers Have to Say!

  • James M. " After 25 years of living with a poorly installed system, I finally broke down and decided to replace the whole mess. Jacob came by on a Saturday, his day off, and helped me size a new system and quoted me a fair price. His installers tore out the old system, put in a new system, did the Title 24 requirements, cleaned up and left. All in about 6 hours. The city inspector came by a few days later and signed…"

  • Rebecca G. " We called Oak Island for a quote on a new heating and air conditioning system since ours was very old and at the point where it was dangerous to run. We were pleasantly surprised at how easy the process was. Chris is very knowledgeable and personable, which made our decision an easy one. We were given all the dates and times for the duct removal to the installation of the heating and air conditioning unit and on both days they…"

  • Richard W. " Short version: Hector did me right. Previous contractor gave me a long list of stuff to repair totaling $2,500. None of which he thought I needed. Got me going again for a quarter of that. Shop around for HVAC! These guys have you at a huge information disadvantage, and a lot of the work is in places that you can't easily look for yourself. Oak Island is a reputable company that has been around for a while."

  • Forrest B. " Quietest AC unit I have ever had! These guys are TOP NOTCH and HIGH QUALITY. They pay attention to detail and they care about their work and Customer happiness. HIGHLY SUGGESTED."

  • Mark J. " Tom and his crew went WAY above and beyond to ensure my system was installed correctly and worked the way it should. Oak Island replaced an old Carrier system with a new Lennox one. After installation, they discovered several leaks in the system - in parts that had nothing to do with the part they installed. Nonetheless, they spent hours searching for and fixing the leaks at no extra charge, making several trips out, until it was right. My new…"

  • George C. " Perfect from start to finish. It was a blessing interacting with Jacob, and his recommendations for the installation was spot on. Then Randy and the crew were polite and explained all the details and installation instructions. We have been enjoying the A/C during this heat wave, and we highly recommend Oak Island. Simple the best. Please don't change anything."

  • Rebecca R. " We recommend Oak Island without hesitation. Although a smidge higher in cost than ASI, we were won over by Chris' expertise and professionalism. Once the bid was awarded, installation was scheduled/performed quickly. Ron & crew arrived when they said they would, communicated the job clearly, and efficiently retrofitted our home with a new furnace and AC unit. Our PQ home is 20+ years old so there were glitches to overcome since the house wasn't built to have AC. Ron treated…"

  • Gary-Adela G. " After having two very bad experiences with other contractors and workers on our home remodel, it was very refreshing to deal with Oak Island and heating. Jacob and his team were professional, did everything to code and on time. I've posted two negative reviews giving Yelp readers warnings, I wanted to make sure to also give credit where credit was due. I recommend Oak Island for all your Air conditioning and heating needs."
