I can’t say enough good things about our experience with John and James. Their level of knowledge and enthusiasm for getting our HVAC system replaced were amazing. They took their time with us to help us understand the difference between systems and efficiency, James and his team were professional and patient ,they took the time to answer my questions and explain what they were doing. They showed up on time and professionally installed 2 end to end HVAC systems in one day. Integrity team was a pleasure to work with and we will only be calling them from now on! 10/10 experience, value and timeliness.

Jason is a fabulous technician. Air conditioning went down this morning. I called at 3:30. They had a technician at my house at 5:30. He walked me through what he was doing and where the problem was discussed the benefits of a service plan and got my air conditioning up and running. I would definitely recommend this company.

I called yesterday at 4pm with my AC not working, and they had a technician here by 10am the next morning. The problem turned out to be a clogged drain that had tripped the shut-off switch – something I never would have figured out on my own. What impressed me most was how thorough and professional the technician was. He took videos to show me exactly what the problem was and walked me through the repair process. The actual fix only took about 10 minutes once he diagnosed the issue. I was especially grateful for how patient and kind he was with my 19-year-old son who has autism. He took extra time to explain everything in detail and made sure my son understood what had happened and how it was fixed. That level of care and professionalism really stood out. Fast response, fair pricing, clear communication, and genuine care for customers. I’ll definitely call them again and would recommend them to anyone needing AC repair.

Jason performed the cleaning and check on our air conditioner, clean out the dryer vent, and cleaned up afterwards. He has been very respectful to us and is respectful of our home. We have had great service from this company since they replaced our furnace and AC three years ago.
