"We had a leak from the ceiling and were unsure what the issue was. But we did notice that every time our air conditioner was on, it was leaking more. My friend recommended calling Jacob since he was so helpful for her house. I called him and he was able to come to our house the same day! It's a big deal when the weather is 90 degrees outside and your air conditioner was messed. He was able to diagnose the issue and cleaned out the clogged pipe. I have never met anyone so helpful and thorough with his work. I will recommend him to all my friends and family."

"Great service! I have an old heating system about 20 years old that needed repair. I called a different company and they didn't even want to diagnose the problem. They gave me a quote to replace the whole unit for multiple thousands of dollars!!!! Then I called Jacob. He came out and was so professional. He took the time to look at my system, diagnose the issue, order the replacement parts and fix it! For thousands less. He then followed up to make sure everything was good. Great service!!! Do yourself a favour and call Jacob first!"

"Our Air Conditioning went out on Friday. We called HVAC after the company that installed our system could not respond for at least 3 days and hasn't followed up after 6 days later (Quality a/c)World HVAC responded and Jacob came to our home Friday evening at 8 pm and repaired within an hour. Jacob was amazing! He called yesterday to insure everything was satisfactory! I would definitely recommend HVAC again. A special thank you to Jacob!"
