Zach came early, which I very much appreciated, and got the job done quickly. He was unfailingly polite and took care with putting on the booties and keeping my carpet clean. He managed to get the sprinkler system turned off even though I was quite uninformed about it and could help very little beyond pointing to where things were. I am always happy to have Brothers people come out to do my plumbing, heating, & electric services.

CM Heating performed an electric furnace Diagnostic - Upon investigation, I found that the sequencer has failed which is why all heat elements are not being activated (3 out of 5 work). This is the second replacement sequencer needed in less than 5 years of operation, the unit is an old model of air handler and only source of heat. Replacement of sequencer is needed, however, based on age and efficiency recommend upgrade of system.

Furnaces and thermostats are not mix-and-match appliances. Using the wrong type of thermostat with a furnace will cause operating problems and can be dangerous. Although thermostats look similar, they are designed very differently. There are numerous types of heating systems and thermostat systems and they need to be coordinated for safe and proper operation. There are three types of thermostat systems used today: millivoltage, low voltage, and line voltage.​
