He was very helpful in taking care of my furnace tuneup, pointing out updates that should be made, and making his recommendations about them. I would definitely have him service both my furnace and a/c units next year and in the future! Services HVAC system maintenance.

My air conditioning unit all of a sudden stopped cooling my house. Called integrity and Jason arrived same day to discover the cause. Turned out my unit lost pressure, so Jason recharged my a/c unit and also put dye in the line to see if we can detect if there's a leak in the system. But at this point my house is nice and cool again. Jason was professional, thorough, and helpful. I'm grateful Integrity Heating and Cooling have wonderful technicians that know there stuff.

James did a job above and beyond what any technician has EVER done for us. Thoroughly checked everything, clearly explained all issues and guided us through what to watch for in the future. Totally explained the new thermostat operation and provided real practical advice for future operation and care of the system. Great young man and excellent representative for your company.

Recently I had my air conditioner replaced. James and his crew were right on time, friendly and courteous. He made sure everything was working properly and the work areas were fully cleaned before leaving. I have been a customer for 14 years. I appreciate that they notify you who will be coming by texting you a photo of the service person. Honestly, they have been reliable and consistent in excellent service throughout the years. They truly are committed to making sure the customer is satisfied. I highly recommend them.

First I would say, I have had Integrity Heating and Cooling for many years I trust them with the safety of my family because of their knowledge and workmanship. Todd Chasse is one of the most knowledgeable experienced technicians in this field that I have ever come across. After reviewing my situation with my Central Air unit and Todd explained it in details I was very happy with his knowledge and expertise.

I would say he has the owners of the house and the families that live within it safety that comes first. I will be continuing all of my services with Integrity Heating and Cooling because of Shawn. Bob Nard jr.

The tech sent to our home, Sean, was very professional, thorough and knowledgeable. He explained what was imperative for us to replace and what was non-essential along with the consequences of what could occur if we let things get worse. He provided details regarding cost and time frame necessary to complete our installation. We were extremely happy with his expertise and patience.

It was a delight to have Todd Chase as our technician. He was kind, courteous, and thorough with his work performance. He certainly deserves a 5 star rating. Their slogan of "just a phone call away" holds true as they called at 8:15am and arrived by 10am. Thank you for your service!

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.
