  Oleg was great! He came out last minute and knew how to find the issue and fix it. He took the time to show me where the problem was and walked me through how to clean the unit to prevent future issues. Thank you!

  I had an excellent experience with OIG HVAC. Oleg responded incredibly quickly when I needed a repair and was able to come out right away. Oleg was professional, honest, and efficient from start to finish. Oleg diagnosed the problem quickly, explained everything clearly, and completed the repair at a very fair price. It’s refreshing to find a company that combines fast response times, quality workmanship, and reasonable pricing. If you’re looking for a reliable HVAC company in Santa Clarita, I highly recommend OIG HVAC. I’ll definitely be using them again for any future heating and air conditioning needs.

  These people saved my life!!! Another company (Affordable Air) had come out to fix my heatpump. They said it would be 15k to replace it and disconnected the whole thing "for my safety". I couldn't afford that. So we went for nearly two years with no heat or air. And I had just gotten two hairless cats! I was very worried about them in the cold! My friend suggested I have these wonderful guys take a look. FOR FIVE HUNDRED DOLLARS they repaired my unit. Yes, it is old and will give out soon but I'm nearly two years now with heat and AC thanks to these miracle workers!

  I highly recommend Oleg and Igor Gladchenko and OIG HVAC for any residential and business heating and air conditioning needs! As a Ukrainian-American business owner, Oleg brings a rare combination of strong business ethics, professionalism, and deep industry expertise to his work. What truly sets Oleg and Igor apart is their respect for your home and business. They are exceptionally clean workers; when the job is completely done, the workspace is spotless and restored to its original condition. If you need reliable, honest, and high-quality HVAC repair or replacement, OIG HVAC is a must to call.

  I highly recommend OIG HVAC! Oleg and Igor repaired my HVAC system and did an outstanding job. From the very beginning, they were honest, upfront, trustworthy, and very reasonably priced. They took the time to explain everything clearly and never tried to upsell unnecessary work. Since the repair, I’ve continued using them for all of my HVAC maintenance, and the service has been consistently excellent. Their professionalism, reliability, and attention to detail give me complete confidence that my system is in good hands. My AC is now running like new, and I couldn’t be happier with the results. If you’re looking for a dependable HVAC company that truly cares about its customers, OIG HVAC is the company to call!
