Description of Work: Furnace died on coldest day of the year. Michigan Building and Mechanical responded quickly within a couple hours. I got quotes from a couple suppliers for furnace and air conditioner, plus installation. MB & M was flexible on their price and matched a lower bid.

Description of Work: He first checked to make sure unit was completely thawed (our AC unit had frozen up on July 4). He checked the filter and opened up a panel on the furnace and checked that out. He then went outside and checked the coolant and said it was low, Approx. 1 lb. was added. He put a new filter in , turned on the AC and checked the temperature of the air coming from a register. He told me he had found loose King caps and that could have been a source of a leak so he tightened them.

Description of Work: Michigan Building & Mechanical removed the old HVAC system in our home and replaced it with a new Carrier Infinity Modulating furnace, Two-stage Infinity Air conditioner, Infinity control, Aprilaire whole-house dehumidifier and Bradford White hot water heater. The whole-house dehumidifier was connected between the forced air ducting and return air ducting and set up for humidity level monitoring on a periodic basis. The old hot water heater was drained and removed and the newer model was installed with care not to damage the energy savings tubing in the inlet and outlet connections. Since the old furnace had been exhausted through a double walled stack which combined with the hot water heater exhaust, the technicians ran new PVC for fresh air venting and exhausting spent natural gas for the high efficiency unit. At our request the two PVC pipes were combined into a flat mount plate which improved the looks of that installation from the outside of our home. New ducting was required above the evaporator unit to connect to the existing forced air ducts. The new A/C system replaced a Freon based system and now runs on Puron, a newer refrigerant which appears to handle the outside heat wave very well. When removing the old compressor unit, the Freon was captured and the unit was sealed before transporting. The new A/C was leveled and placed on a new base. Before charging the new system, the technicians placed the system under vacuum for a period of time to insure there were no leaks at the points it was soldered. A pressure check was run on the system after installing the Puron.
