Description of Work: Repaired leaking relief valve on hot water heater. Colt warned me that we probably will need to replace heater soon, but we wanted to buy some time to learn more about tankless heaters, so we requested the repair in the meantime. I appreciated he was honest about our options and did not want us to spend money unnecessarily.

Description of Work: Complete replacement of 2 zone Heating and A/C system, including new furnaces, and inside A/C, outside A/C components. Some re-ducting required, but new seems to work better than the old contractor system. Initial manufacturer problem was encountered, but Mann-In kept after them and got the system running like a top. Very pleased and (now) comfortble. They also integrated whole-house humidifier and filter system that I had added to the original installation.

Description of Work: They replaced the heating/AC system for our home. The owner reevaluated the duct work, and modified the duct system for better distribution of air flow. No one else had even mentioned doing this. They had the air ducts cleaned first before beginning the new installation, and they worked very cleanly. Explained everything, and have been very responsive for service in the two years we've had them.

Description of Work: I used an Angie's deal for annual inspection of two HVAC systems. The Technician arrived on time and performed the annual maintenance. During the inspection he recognized an issue with a humidifier which I knew was not working and he repaired it quickly and efficiently. This an extra charge for his labor which was a reason rate and he performed the task very efficiently. I recommend Mann-In and plan to use them again.

Response from Mann-In Inc A/C & Heating
The description left by this customer is true. Mann-In Inc. canceled their contract with Angie's List on November 30, 2014 and as a result there should not have been any deals available on Angie's List for customers to purchase for Mann-In after this date. This is a reflection of Angie's List and should have never happened had they completed their end of the contract.

Description of Work: Had Mann-In provide our winter check up for our heat. There were some scheduling issues to some uncontrollable issue on their side but we were able to get it done. The technician was incredible nice, professional and honest. I was very happy with his work and would use them again.

Description of Work: Over the last 15 years we have had 2 furnaces installed by Mann-In and our maintenance agreement is with them. They are always on time and professional. One August they even provided us with a heat pump loaner when a part was going to take weeks to arrive. We could not have asked for better service.

Description of Work: Furnish and installed a Carrier gas furnace and air conditioner system. Stan Lee, the estimator, was very professional and the only one who came to the initial appointment with brochures (left them with to read up on product in my decision making process) to show me what the products would look like. When I had problems operating the "I Pad-like" thermoset, they sent out a serviceman immediately and they were all punctual and knowledgeable about the products.
